Abstract: An assembly for product support and deployment for a vending machine includes a product chute, a pusher, a pusher drive assembly, and a controller. The product chute is configured to receive a plurality of products stacked on one another. The product chute includes an exit opening through which a respective product of the plurality of products is dispensed. The pusher drive assembly is operatively connected with the pusher and is configured so as to move the pusher in at least two mutually perpendicular axes. The controller is in communication with the pusher drive assembly. The controller is configured to control operation of the pusher drive assembly such that the pusher pushes the respective product being dispensed towards the exit opening and supports or lifts the remaining products in the chute against the force of gravity prior to the respective product fully exiting the product chute through the exit opening.

Abstract: A vending machine includes a refrigerated enclosure including a housing for storage of an associated pre-packaged food product. The housing has a sidewall with a sidewall opening. A door is mounted to the sidewall for closing and opening the sidewall opening. A drive mechanism is operably connected to the door and adapted to mechanically move the door between a closed position and an opened position. The drive mechanism includes at least one sensing device adapted to determine whether the door is in one of the closed position and the opened position. A door rail is mounted to the sidewall and has a guide track. The door is movably received in the guide track.

Abstract: A massage table for supporting a person during a massage above a surface includes a leg assembly that engages the floor, and a table top that includes six foldable wings, four staging feet and a handle. The frame is made up of rectangular aluminum sections that are welded together to make up the frame and the wings frame. The frame includes a frame base that supports at least a portion of the person above the surface with two legs, the wings are connected to the base of the frame by piano hinge and can fold down independently while still connected to the frame base, the frame sections are made of aluminum but can be made up of various materials. A T-bar face cradle inserts into the head of the table.

Abstract: A drilling fluid for use in high oil viscosity formations containing tar, sand and oil entrained therein. The drilling fluid can be comprised of a polymer in an amount from between 0.05% and 5% by volume, a solvent in an amount from between 1% and 20% by volume and de-emulsifier in an amount from between 0.05% and 10% by volume.

Abstract: A computer controlled rotary piston engine includes a blower housing containing a rotatable impeller assembly, for pushing ambient air into the housing, and forcing the air to pass through a normally open valve mechanism into a combustion chamber. A plurality of fuel injectors are selectively operable for injecting fuel into the combustion chamber, followed by selective operation of at least one spark plug for igniting the fuel/air mixture, thereby causing the valve mechanism to close, and the combustion gases to pass through a plurality of spaced apart intake manifolds into always open input ports of a piston chamber for rotating a vaned or bladed rotary piston therein, followed by spent combustion gases being forced out of a plurality of spaced always open exhaust ports into an exhaust manifold. The distance the piston travels during a power cycle is adjustable, and inversely proportional to the frequency of combustion or number of combustion cycles within a given period of time.

Abstract: Water based drilling fluid compositions which contain at least one viscosity builder and at least one rheological control agent wherein the rheological control agent is an amphoteric polymer, the cationic groups of the amphoteric polymer being quaternary ammonium groups.

Abstract: An isokinetic resistance apparatus includes a motor having an output shaft and a motor controller adapted to control power to the motor to maintain a first constant rotational speed of the output shaft. The output shaft of the motor rotates a driven shaft in a first rotational direction at a second constant rotational speed. A force receiving member is coupled with the driven shaft by a force transmitting linkage having a unidirectional clutch. A force exerted upon the force receiving member in the first rotational direction is transmitted through the driven shaft and the drive linkage to the output shaft of the motor. The motor controller adjusts power to the motor to compensate for such force and proportionately increase resistance to maintain the first constant rotational speed of the output shaft.

Abstract: The fire extinguisher includes a container filled with a fire extinguishing liquid and having a normally closed main outlet and support structure extending through an opening of the container wall. A compressed gas cartridge located in the container is supported by the support structure. The support structure has an opening formed therethrough which leads to the end of the compressed gas cartridge. A plunger, an explosive charge, and a heat sensitive fuse, the latter of which has a portion is exposed to the exterior of the container, are located in the opening of the support structure. In the presence of high temperature, the fuse causes the explosive charge to explode and force the plunger to rupture the cartridge which release the gas into the liquid in the container by way of a normally closed gas outlet formed through the wall of the support structure. This causes the liquid to be forced out of the container by way of the normally closed main outlet.
