A slide-out or retractable room for a mobile living quarters, such as a recreational vehicle, is provided with actuating assemblies mounted on opposite side walls of the slide-out room and the adjacent wall of the main living area. The actuating assemblies include a pair of parallel gear racks mounted on the side wall, which are engaged by pinions rotated by torque shafts mounted on the main living quarters. Each torque shaft is rotated by a separate motor. A roller engages a bearing surface on the lower portion of the gear racks. Accordingly, the slide-out room is extended and retracted by rotating the torque shafts to cause the gear racks and the attached slide-out room to extend and retract. The weight of the slide-out room is supported by the rollers, thereby supporting the slide-out room off of the floor of the main living quarters as it extends and retracts.

A synchronizing control operates the motors.

A leveling jack for a vehicle, such as a recreational vehicle, includes a leveling piston and cylinder, a bi-directional, reversible pump, and a reservoir within a common sealed housing that does not require exterior fluid connections. The piston is extended from the housing to contact the ground and effect leveling by operating the pump in one direction, and is retracted into the cylinder by operating the pump in the other direction. Accordingly, the leveling jack is a self-contained unit, and does not require a central hydraulic unit and the necessary hoses between the jack and the central hydraulic unit as needed in the prior art.

An adjustable watercraft awning includes a first base, a second base, a first frame member, a second frame member, an actuator, and a flexible cover. The first base is adapted to mount on a first side of a watercraft, and the second base is adapted to mount on a second side of the watercraft. The first frame member is pivotally coupled to a rear region of each of the first and second bases, and is movable between a lowered position and a raised position. The second frame member is pivotally coupled to a front region of each of the first and second bases, and is continuously movable between a lowered position and a first raised position and also between the first raised position and a second raised position. The actuator is coupled to transmit mechanical power to the second frame member only.

An anodized aluminum hydraulic leveling cylinderfor a vehicle includes an extruded hollow bodyhaving a vehicle attachment portionfor attaching the body to the underside of a vehicle. A pistonis slidably fitted into the interior of the body. The piston is formed of ductile aluminum capable of being machined to a desirable shape and dimensions. The piston is hard anodized and PTFE coated for durable and silent operation. Hydraulic oil passage meansis formed in the body, and a capwith a pair of dual flow-through passagesis attached to the top endof the body for permitting the flow of pressurized hydraulic oil into and out of the interior of the body to effect axial movement of the piston. Hydraulic fluid may be transferred through one or more hollow mounting bolts.

A configuration of heat engine, a stirling engine, is presented that utilizes an even number of axially opposed, axially aligned cylinders and that can be made using almost unlimited variations in the number of cylinder pairings, size, length, operating temperatures and pressures, materials, heating and cooling sources, etc. The axially opposed configuration of the cylinder pairs maximizes engine efficiency by minimizing dead space, maximizing thermal isolation of the hot and cold sides, maximizing regenerator efficiency, maximizing the free flow of the working fluid and allowing the engine speed (rpm) and power output to be rapidly and precisely altered and controlled. When driven, the engine acts as a heat pump, with all of the aforementioned improvements and advantages over previous kinematic heat pumps and wherein the piston timing can be varied for precise temperature control and to provide a method of defrosting that requires no additional parts or heat source.
