Abstract: An absorption cycle based system is disclosed for using waste heat from a vehicle and providing selective heating, cooling, and dehumidifying to a vehicle compartment. The system includes a waste heat loop in thermal communication with a power generating unit of the vehicle, and a vapor absorption subsystem. The vapor absorption subsystem may include a thermal compressor in thermal communication with the waste heat loop, a radiator unit, a condensing unit for heating the vehicle compartment, an evaporating unit for selectively cooling and dehumidifying the vehicle compartment, and a plurality of valves configured to selectively direct refrigerant through the vapor absorption subsystem. The vehicle compartment may include at least one of a passenger cabin, an electronics housing, a battery pack, an engine compartment, and a refrigeration compartment.

Abstract: A fuel dispensing nozzle is provided with fuel activated levers that engage the vehicle fill pipe to prevent drive-off without paying. Fuel pump pressure acts on plungers to pivot fill pipe levers, against spring pressure, to lock the two together. Movement of the levers is initially prevented by a trigger that is spring biased forward on the nozzle spout. Since the fill pipe is not large enough to pass the trigger, insertion of the spout into the fill pipe moves the trigger against spring pressure to uncover the levers. The levers are locked to the fill pipe as long as pump pressure is present. Removal of fuel pressure allows the levers to be withdrawn by spring action. A breakaway joint is provided to stop fuel flow in the event of drive-off with the fuel nozzle in a fuel filled pipe.

Abstract: A building block includes ends having recesses and ribs. Each block end has a recess about ½ the width of a stud in the upper portion so that when blocks are placed end to end they can support a stud. The front and back of the blocks ends have vertical braces or protrusions that form vertical recesses for mortar and a mortar overflow area. The front of the block can have a facade with its ends extending around its front corners.

Abstract: An engine is cooled using high pressure water injected into the piston with the water converted to high pressure steam by the heat from combustion with heat transfer taking place in passages in the piston and in and between grooves in the piston and the cylinder sleeve. The high pressure steam is conducted between the piston and cylinder walls to lubricate, so there will be no need for piston rings, with a part of it passing into the crankcase, and a part of it going into the combustion chamber where it contributes to power production. The piston skirt has a spring-loaded washer access to a void in a lower passage for balancing pressures.

The piston body has a spring-loaded valve in a passage to balance pressures and control steam flow into the upper piston and combustion chamber.

Abstract: Drive off is prevented by having a grasp assembly engage the restrictor plate of the fill pipe of a motor vehicle when the nozzle spout is inserted. After the fuel pump is started and pressure is placed on the fuel, fuel is admitted into the nozzle by pressing on the hand lever to open the poppet valve. Fuel pressure in the nozzle activates a lock actuator system, to prevent removal of the spout from the fill pipe, by a lock system that prevents a grasp assembly latch from retracting from the fill pipe restrictor plate.

Abstract: Molded composite polymer construction blocks are made that are easily assembled, using alinement pins and apertures, with channels for insertion of sealant and vertical passageways for pipes, wires, etc. Stud supporting cavities in one side of the block extend into the ribs or end walls. The cavities can be provided with a protective metal insert. Studs or wooden blocks can be inserted into the cavities. The wooden studs or wooden blocks of various lengths provide spacing for insulation and/or drywall installation.
