Fluid transfer device may be configured as a vacuum pump, including blood and blood constituents. Fluid transfer device used for assisting in the pumping of blood through a patient's heart for reducing the load on the patient's heart, sheer forces and blood pressure on the inner walls of the heart are reduced. Pump may be used as an implanted cardiac assist device, such as an aortic assist device, a ventricular assist device, or as a complete artificial heart. By use of a vacuum, the inventive fluid transfer device may be operated at no more than atmospheric pressure. A pre-charged pressure tank may be used dependent on the application requirements, such as in the case where fluid pressure of the pumped fluid, including the backpressure of body fluids, in the case where pressure greater than atmospheric to sufficiently expel pumped fluid.

Nondestructive fluid transfer device

Fluid transfer device configured as a vacuum pump particularly suited for nondestructive transfer of fluids, including blood and blood constituents. Fluid transfer device used for assisting in the pumping of blood through a patient's heart for reducing the load on the heart, reducing forces and blood pressure on the inner walls of the heart is reduced. Examples are aortic assist device, a ventricular assist device, or artificial heart. Industrial applications include the pumping of fluids, including destructible fluids such as foodstuff with or without food constituents of various sizes within the foodstuff. Food and other fluids may be stored until they are dispensed. By use of a vacuum, the device is operated at no more than atmospheric pressure. A pre-charged pressure tank may be used, such as where fluid pressure of the pumped fluid, including backpressure of body fluids, where pressure greater than atmospheric is required to expel pumped fluid.

Tool includes a fixed handle and a movable, lockable handle. A working end of the tool includes an upper jaw and a movable lower jaw. A passage may be provided in one or both of upper and lower jaws. A sealing device may be provided in the upper jaw, the sealing device being disposed adjacent to the passage. Lower jaw may likewise include a passage therein. In use, an elongated object such as a tube may be inserted into the passage in the lower jaw and then into the passage in the upper jaw adjacent the sealing device. When the lower jaw is engaged with the upper jaw, the lower jaw compresses the sealing device and sealingly engages the sealing device, the passage, and the tube disposed therein. In that manner, a seal is achieved. In the case where an opening having a coupling is fluidly connected to the upper jaw, a sealed, fluid connection may be established between the coupling on the upper jaw and the tube engaged by the seal.

Quick release tool for engaging elongated objects, particularly suited for use with tubing

Fluid decontamination device includes a base having a fluid passage in it. An observation window is provided in the base for allowing a user to observe a fluid in the fluid passage. A differential pressure indicator, such as a vacuum indicator, is operatively connected to the fluid passage for indicating the relative pressure in the fluid. An indicator light which turns on when the differential pressure in the fluid passage is less than a predetermined differential pressure may be provided on the differential pressure indicator. A filter may be fluidly connected with the fluid passage for filtering out one or more contaminants present in the fluid.

Contaminant flushing device, system, and method, particularly suited for refrigeration system servicing

A reciprocal type of pump structure wherein a piston has a linear function actuated by a pair of coils energized alternately and includes a plurality of tapered flutes. A check valve in an outlet of the structure which stretches to open said outlet under the impact of expelled fluids and of its own volition retracts to the closed position immediately upon the cessation of fluids being expelled.

A game apparatus is disclosed in which a playing piece such as a ball, puck and the like is adapted to move over or strike a playing surface in turn formed by one of a pair of flexible sheets on which electrical circuitry is disposed. Another sheet having openings at preselected areas is disposed between the flexible sheets so as to normally maintain pairs of contact portions of the circuits in opposed spaced relationship to each other. As a playing piece moves over such preselected areas, its weight causes the first flexible sheet to become downwardly depressed such that a contact pair of circuits is electrically closed and a game event is signalled thereby. The game may be a pinball machine including electronic/microelectric circuitry, as a game processor input subsystem, and an alpha-numeric score-keeping readout and may also include audio and visual signals.

Pinball machine and flexible sheets with circuit therefor

A doll which is adapted to simulate kissing by leaving a lip imprint of marking material on objects contacted therewith is disclosed. The head of the doll is provided with an inwardly directed cavity in the oral region thereof which in turn is adapted to receive a pad of porous material in which the marking material is impregnated. The end of the pad is provided with a lip shaped extension adapted to project outwardly from the face of the doll so that when the doll's face is impressed against an object, an imprint of marking material in the shape of the lips is produced. In one form of the invention the pad is received in a closed cavity and in an alternate form of the invention the pad is mounted at the forward end of a pushing member slidably mounted in the doll's head so that a more positive 'kiss' imprint may be made.

Kissing doll

A child's riding toy of an overall 'scooter' type configuration. A longitudinally orientated vehicle body having supporting wheels at the forward and rear ends thereof is adapted to support one of the knees of the child riding thereon. An outrigger portion extends laterally from the side of the body and is provided with a third wheel so as to enable three-point rolling support for the vehicle. Separate handles are provided above the forward and outrigger wheels such that the child may simultaneously grasp both such handles while supporting his body in a forward leaning position above the vehicle while the unsupported leg is available for propulsion. The forward wheel is capable of limited pivoted movement with respect to the vehicle body such that the child may steer the vehicle through a variety of exciting turning maneuvers.
