Abstract: A wheelchair assembly includes an occupant seat having a central shaft for mounting the seat on an undercarriage for universal tilting movement, for vertical movement along the shaft axis and for rotation about such axis. The undercarriage has a plurality of ground engaging wheels driven together by a driving mechanism which includes a drive motor and steered together by a steering mechanism which includes a steering motor. The steering motor may be operatively connected with both the seat and the wheels for turning them together by operation of a control assembly, or the steering motor may be operatively connected with only the seat or with only the wheels for independent operation. Otherwise, the steering mechanism may couple the seat with the wheels while the steering motor is disconnected so that wheel steering may be operated by a manual turning of the seat. An analyzer assembly compares the direction of travel chosen by the seat occupant to the actual orientation of the wheels and then directs the steering motor to align the wheels to the direction chosen, without turning the chair. And, the seat is automatically tilted toward a direction opposite that to which, it tends to lean when the wheelchair moves up an incline or down a decline.

IPC: F02M37/18
Filed: 1980-11-20
Abstract: Loss of valve opening pressure (VOP) attributed to wear of contacting portions in fuel injection nozzle valves (22) is limited due to provision of a valve tip (38) having a lower portion (38a) which repetitively engages only a lower portion (40a) of a valve seat (40). Advantageous wear of the engaging portions increases the seating area but reduces the effective differential area for fuel pressure to act against, thus reducing the need for increased pressure to open or unseat the valve (22). Increased clearance results in less wear between a reciprocating valve (36) and a cooperating guide (34) which also contributes to reduced VOP loss during the life of such nozzle valves (22).

Abstract: When coating the inner surfaces of a furnace with strips of refractory mineral material of synthetic material such as felt, one often uses anchors which are welded to the shell of the furnace, which anchors are provided with recesses such that little plates can be secured to the anchor after having made a quater of a revolution. These anchors represent energy loss and it is a time consuming job to weld all those anchors. 
     This is eliminated by using metal strips (5) with recesses (8) which are punched out to at least one side. One can make now felt packages and some strips are provided with slots (10) so that they can simply be attached to the furnace frame (2). If the side walls are coated by vertical packages, there also is no sag under the influence of the own weight.

Abstract: A simplified method of waterproofing masonry walls such as basement walls subjected to water from the outer surface by coating the inner surface with an anionic silicone emulsion that dries to produce an elastomeric film is disclosed. The silicone emulsion consists essentially of an anionically stabilized hydroxyl endblocked polydiorganosiloxane, amorphous silica, and an organic tin salt, the emulsion having a pH of 9 or greater. 
     The emulsion coating when dried provides an elastomeric film that bonds to the surface with sufficient force to resist the pressure of any water that may diffuse through the wall from the outer surface. The method of this invention provides a waterproof coating that also resists the effects of cracks in the substrate, temperature extremes, molds, fungus, or mildew, as well as possessing a long useful life.
