Abstract: A kit for retrofitting a door with a remotely controllable locking mechanism having a combination key-operated deadbolt lock and door knob latching lock for a door. A housing for the operating parts is insertable in a mortised pocket or cavity in the latch edge of the door or it may be attached to the exterior surface of the interior well of the door. The electronics to operate the mechanism sends a signal to a receiver installable in the wall near the locks. Power is supplied to solenoids to simultaneously activate the locking and unlocking mechanisms of the deadbolt and the door knob latching lock when the kit is assembled in the door. Manual key overrides are provided for the deadbolt and for the latch.

Abstract: An apparatus for mixing and dispensing particulate-laden liquid or immiscible liquid, samples from a container or vessel. The apparatus is attached to the top of the vessel with a mixing tube extending downwardly into the liquid sample. A valve piston disposed in the tube may be moved from a closed position to an open position while the liquid sample is continuously agitated and circulated through the mixing tube. The agitation system lifts a portion of the liquid sample through the valve piston and out a discharge port for eventual assaying.

Abstract: A portable cabinet for effecting the cooling of beverage containers by utilization of a thermoelectric cooling unit comprises a rectilinear cabinet having spaced inner and outer walls formed of plastic and having the space between filled with a foam plastic. An upper container insertion opening and a lower container removal opening is provided in the front wall of the cabinet. A core block is inserted within the inner walls of the container and cooperates with the inner wall surfaces of the cabinet to define a channel extending in a downward direction between the insertion opening and the discharge opening, thereby permitting an inserted cylindrical container to roll through the channel under the influence of gravity.

Abstract: A jet pump system is shown that utilizes waste heat to provide heating and/or cooling. Waste heat diverted through a boiler causes a refrigerant to evaporate and expand for supersonic discharge through a nozzle thereby creating a vacuum in an evaporator coil. The vacuum draws the refrigerant in a gaseous state into a condensing section of a jet pump along with refrigerant from a reservoir in a subcooled liquid form. This causes condensation of the gas in a condensation section of the jet pump, while moving at constant velocity. The change in momentum of the fluid overcomes the system high side pressure. Some of the condensate is cooled by a subcooler. Refrigerant in a subcooled liquid state from the subcooler is fed back into the evaporator and the condensing section with an adequate supply being insured by the reservoir. The motive portion of the condensate is returned to the boiler sans subcooling. By proper valving start-up is insured, as well as the ability to switch from heating to cooling.
