A modulated steam cooker in which food to be cooked is received in an oven chamber having an access door associated with a door switch, steam being fed directly into the oven by a steam generator having an electric heater immersed in a pool of water. The heater is connected through the door switch to a power source whereby the generator is powered only when the door is shut. The pressure of steam draining from the oven is sensed by a pressure-responsive switch interposed between the heater and the power source, the pressure switch intermittently interrupting the power supplied to the heater only when the sensed pressure exceeds a predetermined level somewhat above atmospheric pressure, thereby modulating the generation of steam supplied to the oven as a function of the quantity and temperature of food therein to effect efficient cooking of the food. Mounted on the steam generator is a spray head supplied with water only when the door is opened. The head then emits a spray of water which quenches the steam in the generator, the resultant pressure drop causing steam to be sucked back from the oven into the steam generator whereby little steam escapes from the opened door and the person opening the door is not subjected to hazardous steam.

A waste compaction and liquid extraction system and method are provided. The system includes a tank for containing liquid and solids, and a tray that seats on the tank. The tray includes a feeding mechanism for moving bags of waste across the tray, and a stuffing mechanism for pushing the bags down into the tank. A rotary disc impeller is mounted in the tank for grinding the solids to form a mixture of liquid and solids. The impeller has a rotating blade with inclined and bevelled cutting members. A stationary helical screw is horizontally mounted to the output port of the tank. The screw has a receiving end adjacent to the output port and a discharge end. The tank conducts the mixture to the receiving end of the screw. A sieve is provided having a cylindrical sieve surface surrounding the screw. The liquid drains through the sieve. The sieve is rotatably mounted to the output port of the tank. The sieve rotates about the screw to move the solids longitudinally towards the discharge end of the screw. A restrictor at the end of the sieve maintains backpressure to squeeze liquid out of the partially dried solids. A housing surrounds the sieve. The housing is mounted to the input port of the tank for communicating liquid that drains from the sieve back to the tank by way of the input port.

A flag display device for mounting a flag or pennant to the exterior surface of a vehicle, such as a windshield, window, or roof includes a flag staff having a flag affixed at one end and an annular base member at the opposite end. A suction cup depends from the base member for securing the flag display device to the surface. The base member also has a plurality of flexible legs radially extending from the annular ring to the surface which engage the surface at individual, separate and distinctly spaced contact points adjacent an outer perimeter of the suction cup when the suction cup is depressed, so that a force applied to the flag staff is transferred to the surface through the individual leg contact points and the suction cup and the flag staff remains stable even when wind forces are applied to the flag and flag staff. The flag display device further includes a mounting member for securing the flag staff to the base member. The mounting member provides an adjustment mechanism for adjusting a position of the flag staff relative to the base member.

A modular 'knock-down' type shelving system having adjustable height shelves includes a plastic support post having a generally right equilateral triangular cross-section. The support post is composed of pultruded thermosetting plastic having unidirectional E Glass fibers extending therethrough and a thermoplastic coating bonded to the outer surface thereof. The inner surface of the interior side of the support post is bowed outwardly. As a result, when a wedge member is disposed on the interior side of the post and the support post and wedge member combination supports by wedge action a sleeve comprising an end beam and a collar, the interior side of the support post is urged outwardly and is supported by the wedge member. The collar is locked to the end beam when a tongue of the collar passes through a slot in the end beam into a rotatable lock in a blind hole in the bottom of the end beam. A plurality of shelves are adapted to be snap-fit over a rectangular support structure comprising two end beams, and two side beams and a center beam connecting the two end beams. In this manner the shelf can be easily assembled and disassembled and supported on a support post at a predetermined height.

A safety hypodermic needle and shielding cap assembly attachable to a standard syringe adapted to prevent the needle after it has been injected in a patient and then withdrawn, from accidental sticking the operator. The syringe includes a fluid chamber provided at its front end with a projecting nozzle surrounded by a cylindrical socket. The assembly includes a hollow hub receivable in the syringe socket and a needle mounted on the hub and extending along its longitudinal axis whereby the nozzle projects into the hub to deliver fluid to the needle. Mounted adjacent one side of the hub is a short track on which is slidable a flexible push rod on whose upper end is laterally attached a shielding cap having a center bore in alignment with the needle. In the operating mode of the assembly, the push rod is retracted and the cap is then telescoped on the hub to expose the needle for injection into a patient. In the shielding mode of the assembly, in effect after the needle is withdrawn from a patient, the push rod is extended by the operator to raise the cap bore above the tip of the needle whereby the cap then shields the tip. Should pressure be applied accidentally to the shielding cap seeking to force it toward the needle, the cap which is cantilevered from the track by the flexible rod will then swing to an offset position in which the bore is out of line with the needle tip.

A dental X-ray aiming device adapted to place an X-ray film packet having sharp edges at a proper position in the oral cavity of a patient. The device includes a packet holder that serves to shield the sharp edges of the packet to avoid direct contact with tissue within the oral cavity and the resultant discomfort, pain or trauma. The holder is formed by a rectangular frame of resilient plastic material within which the packet is socketed, and a bite block joined to the front of the frame which, when clenched between the teeth of the patient, then places the held film packet behind a tooth region to be examined. The device also includes a distance-calibrated guide rod which is detachably coupled to the bite block, and a sighting ring adapted to receive the nose cone of an X-ray unit, the ring being slidable along the rod to a desired position thereon, whereby an X-ray beam is projected from the nose cone in accurate relationship to the film packet.

A two-piece mobile bar which may house a beverage cooling and dispensing system for dispensing cold beverages through a multi-valved gun operated by a bartender stationed behind the bar. The first piece is a base unit defined by vertical end walls bridged by upper and lower sections, the upper section being joined to the end walls at corresponding positions below the upper edges of the end walls. The space between the upper and lower sections is divided into open cells which receive beverage and other containers. The upper section is provided with a sink in which a cold plate is seated, the cold plate having coils embedded therein in heat exchange relationship with ice covering the plate. The coil inputs are coupled to the containers and the outputs to the gun, whereby beverages passing through the coils are cooled before being dispensed. Coupling is effected by a network of hoses which extend through a shallow region contiguous with the front side of the unit. The second piece of the bar, which is detachable from the first, is an integrated serving counter/apron assembly whose counter rests on the upper edges of the end walls and whose apron covers the front side of the unit and conceals the network of hoses and the containers.

A safety hypodermic needle and shielding cap assembly for a standard syringe whose fluid chamber is provided at its front end with a projecting nozzle coaxial with a coupling socket. The assembly includes a needle-supporting hub whose hollow base is coupled to the socket of the syringe, the nozzle then communicating with the needle. Encircling the hub and attached thereto is a resilient actuator collar defining an annular space within which is received the lower end of a helical spring surrounding the needle extending from the hub. The upper end of the spring is received in the cavity of a shielding cap having a center bore therein through which the needle is passable. The cap is tethered by opposing lines of unequal length to the collar. In the retracted mode of the assembly, the spring is compressed by the cap, which is provided with a pair of opposed lugs that are inserted in corresponding slots in the long sides of the collar, thereby latching the cap and exposing the needle, so that it can be injected into a patient. After the needle is withdrawn, the assembly is put in its operative mode by squeezing the collar at its short sides to disengage the lugs and release the cap which is carried by the expanding spring to a position covering the needle point, the tether lines of unequal length acting to cant the cap to offset its bore with respect to the needle point.

A cold plate for cooling different beverages drawn from supply cylinders, the cold plate being formed by a rectangular base over which is a run-off roof defined by sloping end and side sections. Embedded in the cold plate are cooling coils terminating in input and output terminals that project from the underside of the base, the coil inputs being coupled by upstream lines to respective supply cylinders, the coil outputs being coupled by downstream lines to a soda gun to selectively dispense the beverages. The cold plate is received in the well of a thermally-insulated sink having an open bottom bordered by a rectangular ledge. The base of the cold plate is seated on the ledge in spaced relation to the sides of the well to define a gutter in which there is a water drain. The sink is filled with ice cubes that cover the exposed surfaces of the cold plate and are in heat-exchange relationship with the cooling coils to cool the beverages flowing therethrough. As ice cubes melt, the resultant water runs off the roof and is collected in the gutter from which it is drained, thereby avoiding the formation of a water barrier thermally isolating the ice cubes from the cold plate.
