Abstract: A bed (10) for patients requiring bed treatment having a cut out (19) in the base (18) beneath which is a toilet pan (22, 23, 25) preferably having flowing water supply (26) and drain (27) connections. A mattress (35) having one quarter (36) removed is positioned on the base (18) with the open quadrant (36) over the pan (22). A movable mattress segment (40) is positioned on the base (18) in the open quadrant (36) of the mattress (35) and is vertically adjustable to align with the mattress top and laterally movable to expose the pan (22) and allow patients to relieve themselves without having to be moved to insert conventional bed pans. The toilet pan (22) is cleaned using the water supply which is controlled by movement of the movable segment (40). An alternative embodiment has an attachable hot and cold water supply (58) with a wash basin (53) to allow patients to wash themselves.

Abstract: A method of operating an internal combustion engine, includes adding to the fuel being supplied to the engine, a combustible oil or grease in a minor proportion of the weight of the fuel. The oil preferably is a member selected from the group consisting of petroleum oil and vegetable oil, and the grease preferably is a member selected from the group consisting of petroleum grease and animal fat grease. The apparatus for use with the internal combustion engine includes a reservoir device for storing a quantity of the fuel additive, and a mixing device which disperses small quantities of the additive, received from the reservoir device, with fuel flowing therethrough to form a fuel mixture for use in the engine.

Abstract: An auxiliary undercarriage for vehicles having pneumatic tires, one of which is flat, includes an elongated member for disposition under the vehicle adjacent the flat tire to help support its axle, a ramp at the rear end portion of the elongated member for guiding the axle to be supported upwardly therealong until it is disposed over a wheel journaled for rotation on the underside of the elongated member, and a clamping device on the front end portion of the elongated member for attaching releasably the elongated member to the nearest bumper of the vehicle. A normally engaged brake mechanism prevents the auxiliary undercarriage from rolling until a brake release device responsive to the axle being disposed above the wheel releases the brake for the wheel. As a result, once the clamping device is attached to the bumper and the brake is released automatically, the vehicle is free to be driven to a service station or other convenient location where the flat tire may be changed in a convenient manner.
