Abstract: A portable antenna support structure which can be carried by a vehicle and includes an inflatable balloon and telescopic extension poles that are pivoted to the sides of the vehicle at the front and back and may be extended radially when the vehicle is at rest. The vehicle carries a storage tank of compressed helium which can be transferred to the balloon for inflating it, the balloon being equipped with an antenna. Guy lines extend from a winch on the vehicle and are passed around pulleys arranged at the outer ends of the fully extended telescopic poles and then are secured to the balloon for holding it and the antenna in a fixed position and at a desired height above the vehicle. The balloon may be pulled down to the vehicle by the winch where the helium may be withdrawn from the balloon for collapsing it and the gas may be compressed in the storage tank until its next use.

Abstract: An orthopedic device which will provide adjustable and yieldable support to the lumbar region of the spine when a person is in a sitting position. It can also provide adjustable and yieldable support to the cervical region of the spine when the person is in a supine position. It can also provide adjustable and yieldable support to the lumbar region when the person is in the supine position. The device has a semi-flexible flat backing member placed behind an air inflatable bladder so as to direct all of the varied and yielding pressures from the air inflated bladder in a forward direction and directly against the spinal column. The inflated bladder presses against a flap provided in a foam rubber front layer to permit the adjustable yielding pressure from the bladder to be distributed evenly against either the lumbar or the cervical region of the spine.

Abstract: A refrigerator water reservoir that takes the place of connecting the refrigerator to the city water supply, the reservoir being connected to the automatic ice maker and to the ice maker dispenser for automatically delivering water to either unit as soon as the ice maker starts operating or when the ice water dispenser is actuated. No alterations are necessary to be made in a standard refrigerator that is already equipped with the automatic ice maker and with the ice water dispenser. The water reservoir assembly is equipped with a motor driven pump and with a water pressure sensitive switch so that the water in the conduit leading from the reservoir to the two solenoid valves, which in turn control the flow of water to the ice maker and to the ice water dispenser, will be maintained at a desired water pressure at all times. The device also has manually controlled means for refilling the reservoir when needed.

Abstract: A laterally tiltable truck or trailer dump body with hinged side panels and hydraulically operated means for tilting the body laterally in the desired direction and for opening the side panel on the lower tilted side. The hydraulically operated means can also lift the dump body to a higher elevation in case the unloading area is at a height where this would be required. The hydraulic controls are preferably in the cab of the truck where they can be readily manipulated by the operator.

Abstract: A portable unisex urinal that can be removably attached to a bathroom fixture, such as a bathtub and can be used by both males and females. The purpose of the device is to use far less water for flushing the urinal after it is used than is required to flush a standard toilet. Also, my device has a drain tube that may be connected to a standard drain already provided, such as the drain for a bathtub to which the device is attached. The portable urinal has a perforated hose extending around its rim and connectible to a removable water containing reservoir that has a manually controlled valve for delivering the desired volume of water into the hose for flushing the sides and bowl of the urinal after each use. The bowl is so shaped as to be readily useable by both sexes.

Abstract: A portable wiping machine for removing water from a wet surface which may be manually moved over the surface and it includes a large drum whose cylindrical surface is perforated and covered with water absorbing material, such as a sponge. The sponge is compressed by its rolling contact over the surface and the expansion of the sponge portion as it leaves the surface will absorb the water therefrom. A sponge compressing roller is yieldingly held in contact with the top of the drum and a water receiving tray is fixedly mounted within the drum interior in a position to catch water squeezed from the sponge. A water retaining tank is supported by the machine and receives water from the tray. The tank can be emptied of water as desired.

Abstract: A commercial dishwasher comprising two or more modulars connected together through which dish-carrying baskets are moved for washing and rinsing the dishes, one or more of the modulars being arcuate-shaped so as to alter a straight line movement of the baskets into one where they are swung through a 90.degree. angle. By connecting two of the arcuate-shaped modulars together, it is possible to swing the dish-carrying baskets through an arc of 180.degree.. Therefore the dishwasher can be positioned in the corner of a room and thus make use of space that would otherwise not be used.

Abstract: An inner cake pan is removably receivable in an outer pan whose side walls are spaced from the side walls of the inner pan for providing a water receiving space surrounding the inner pan side walls for insulating these walls from the oven heat during the baking of the cake. Novel locking means secures the two pans together so that the bottom of the inner pan contacts the bottom of the outer pan and, therefore, the inner pan bottom will be heated more rapidly than its side walls which are kept at a lower temperature than the bottom because of the insulating layer of water encompassing the inner pan side walls. Also, the releasing of the locking means at the end of the cake baking period will cause the water in the outer pan to float the inner pan and raise it for ready removal from the outer pan.
