A latching mechanism selectively maintains a first member and a second member in secured engagement by the interposition of a striker plate, mounted upon the second member, between spaced apart arms carried by a latching cam mounted on the first member for pivotal movement and locked in a latching position against such movement by a locking member, and moves the first member away from the second member upon selective release of the secured engagement by the actuation of a push-button assembly which unlocks the locking member and allows the latching cam to be moved out of the latching position by a biasing spring so that one of the spaced apart arms pushes against the strike plate to move the first member away from the second member. Selective movement of the first member toward the second member engages the one of the spaced apart arms with the strike plate and moves the latching cam against the biasing force of the biasing spring until the locking member locks the latching cam in the latched position, with the strike plate interposed between the spaced apart arms of the latching cam. In the event of a jam, an auxiliary latch retains the locking member in an unlocked position independent of the push-button assembly.

A novel thermoplastic manifold and thermoplastic fluid fittings for the distribution of fluids, such as pressurized carbonated water, has an elongate tubular thermoplastic conduit with a plurality of apertures spaced along its length for receiving the thermoplastic fittings. Each fitting has a spud extending from one end thereof with a sonic energy director around the perimeter thereof. The fittings also include a saddle portion having a pair of arcuate sonic energy directing ridges thereon spaced on each side of the spud. Each fitting is fastened and sealed to the conduit by the sonic welding of the spud perimeter to the conduit aperture perimeter followed by the sonic welding of the saddle to the exterior surface of the tube.

The present invention discloses a method and apparatus for maintaining cold carbonated water in a beverage dispensing device so that unacceptably warm water is not dispensed therefrom. A modified beverage dispensing apparatus is shown including a carbonated water supply, a cold plate, a cabonated water supply line extending through the cold plate, and in fluid communication with a carbonated water plenum immediately adjacent and in fluid communication with a plurality of beverage dispensing valves. An electronic control device connected to a temperature sensing thermostat located in the plenum and to a solenoid discharge valve of the plenum. The control device is also connected to a temperature sensing thermostat in the cold plate and to a pressure sensor located in the line between the source of compressed carbon dioxide and the carbonated water reservoir. In operation, the control device provides for sensing of the temperature in the plenum so that the solenoid valve can be operated to discharge carbonated water from the plenum if the temperature thereof rises above a predetermined value. So that the water therein can be replaced by water of a suitable lower temperature. The control device also senses cold plate temperature and CO2 pressure so that unacceptably high temperature or low pressure respectively thereof is indicated to the operator and so that the control device can interrupt beverage dispensing.

A refrigeration control system having a temperature sensor responsive to condenser temperature. The sensor turns a condenser fan on and off in order to maintain the condenser temperature within pre-determined limits and also shuts down the refrigerant compressor in response to a predetermined maximum temperature.

An ice cube makes has a generally upright gridded evaporator, a hot gas defrost for harvest of cubes, a storage bin below the evaporator, a hinged cube and water curtain between the evaporator and the bin, a new and improved control for the freeze cycle, and a new and improved control for the harvest cycle. The freeze cycle control has a temperature sensor, on a backside of the evaporator, circuitry to count down a predetermined time after a predetermined plate temperature has been sensed, the circuit terminates the countdown if the plate temperature exceeds the predetermined temperature and restarts the countdown when the predetermined temperature is again reached, and the circuit switches the refrigeration from freeze to hot gas defrost when the countdown is completed for harvest of the ice cubes; the harvest control has an ice curtain sensor connected to the refrigeration control, and a lever between the ice curtain and the sensor, when the curtain is opened by ice cubes the sensor picks up the lever movement and the control switches the refrigeration from the defrost to the freeze cycle.

A rigid thermoplastic manifold for the distribution of pressurized carbonated water has an elongate tubular thermoplastic body with a plurality of apertures spaced along its length, a plurality of identical thermoplastic outlet fittings which each have at inlet spud with a sonic energy director and a pair of arcuate sonic energy directors spaced one on each side from the spud, each outlet fitting being fastened and sealed to the tube with three discrete sonic welds. A method of making the manifold is also provided.

A method of and apparatus for dispensing both particulate ice and cold beverage wherein a common supply of ice is used firstly for dispensing and then secondly for cooling of the beverage. A pair of co-axial rotors are co-rotated about a common vertical axis by a single motor, the upper rotor dispenses particulate ice off of an annular upper bottom. All ice that falls through the open center of the upper bottom irreversibly falls down upon a cold plate and the lower rotor moves the fallen cooling ice on the cold plate for enhanced cooling.

An improved commercial cube/crushed ice making machine includes a refrigeration unit having a water-to-refrigerant heat exchange condenser operatively connectible to an external water supply for heating water therein. The condenser provides for improved efficiency in the refrigeration unit over a conventional air-cooled condenser. Also, the water heating capability of the ice-making machine preferably functions as a secondary heat source for the external water supply, thus providing savings in energy costs for the primary water heating source. Further, the heat exchange relation between the refrigeration unit and the external water supply is determined by an improved control system which is responsive to both a refrigerant pressure at the condenser refrigerant outlet, and the water temperature at the condenser water outlet for controlling water flow through the condenser while maintaining a pre-determined refrigerant pressure in the heat exchange means.
