Title: Vinyl composition tile heating system
Inventor: CHOBOTER GEORGE E
IPC: B26D7/10
Filed: 1995-08-10
Granted: 1999-02-02
Abstract: A method and apparatus is provided for heating vinyl composition tiles which are then amenable to cutting with a knife along complex contours without damaging the tiles. A stack of heating trays are located within a protective housing. The housing is supported on wheel means for ease of transport about the worksite and has one open side so that tiles can be loaded onto each of the trays. A discrete electrical heating element heats each tray and tile to a uniform temperature which renders the tile sufficiently elastic to be cut along any desired contour without fracturing. The trays are spaced appropriately so that tiles can be individually seized for cutting by the installer. The combination of the number of trays and the heating element's heat transfer capability enables an installer to repeatedly seize a sufficiently heated tile, re-load the vacant tray, and then seize another heated tile from the next sequential tray on a cyclical, sustainable basis. For added convenience, it is preferable that each tray be provided with a mechanical tile extractor and that the housing contain a cold tile storage compartment.

Title: Magnetic coupling of a waveguide switch to a coaxial switch
Inventor: CAPPELLI GUIDO G
IPC: H01P5/08
Filed: 1996-02-08
Granted: 1999-08-24
Abstract: A dual switch for coupling a waveguide microwave switch to a coaxial microwave switch. The waveguide microwave switch has a waveguide hollow member and a waveguide rotating section rotatably mounted about a rotational axis within the waveguide hollow member at one end. The coaxial microwave switch has a coaxial hollow member adjacent to the one end of the waveguide hollow member and a coaxial rotating section rotatably mounted within the coaxial hollow member about an axis coaxial with the rotational axis. The waveguide microwave switch is coupled to the coaxial microwave switch by at least one set of cooperating magnets fastened at a given radial distance from the rotational axis to the waveguide rotating section and the coaxial rotating section respectively, such that any rotation of the waveguide rotating section about the rotational axis will be followed by a corresponding rotation about the rotational axis of the coaxial rotating section. The set of magnets includes two magnets located radially opposite each other on the waveguide rotating section near its end and two pairs of magnets located radially opposite each other on the coaxial rotating section so that the magnets are centered between the pairs of magnets and repulse each other. This eliminates any openings between the waveguide microwave switch and the coaxial microwave switch and thus any radio-frequency leakage between the two switches.

Title: Sprayer suspension and steering
Inventor: MAIWALD MARVIN ANTHONY
IPC: B62D21/14
Filed: 1996-04-25
Granted: 1999-11-02
Abstract: An agricultural sprayer suspension includes four generally identical independent strut suspension assemblies each having a pneumatic spring supported above a strut shaft which is received within a strut journal connected to an adjustable axle. A scissors assembly located above the axle maintains wheel steer while facilitating vertical movement of the strut shaft within the journal. On non-steerable wheels, the lower end of the scissors assembly is connected to the journal to maintain a preselected wheel orientation. For steerable wheels, the lower end of the scissors assembly is connected to a hydraulic steering structure which allows axle adjustments for varying wheel tread. Similar construction of the steerable and non-steerable wheel assemblies reduces the number of different parts required and facilitates selective construction of sprayers with either two-wheel or four-wheel steering. A centrally located cab and sloping hood structure provide good visibility and direct viewing of all four wheels.

Abstract: A laundry washing machine in which a suitable level of water is automatically determined for any particular load size. The machine is operated to first determine an initial estimation of the clothes load and to then fill to a water level suitable to the initial load estimation. The machine is then operated in such a way to check if the estimated water level is actually sufficient for the clothes load, essentially by determining the resulting load on the laundry machine motor. If the water level is found to be insufficient then more water is added before the checking routine is carried out once again. When the water level is determined to be suitable for the clothes load, washing is commenced.

Abstract: A load-bearing structure having a set of uniform voids (12) functions to resolve the forces imposed by developing compression in the material having the voids (12) and minimizing the amount of tension developed in the material. For the voids (12) to have this function, they must be deployed in a particular fashion. The voids (12) are deployed to encompass a particular set of points. The set of points are such that each point in the matrix is spaced an equal distance from twelve and only twelve adjacent points of the matrix. The distance between the points does not matter as long as all are uniformly distanced in accordance with that rule. If the structure is considered to be composed of a closely packed set of hypothetical rhombic dodecahedra (RD) and the four-edge vertices of each of those hypothetical RDs are truncated, the result will be a set of cubic voids (12). The center of each of those cubic voids (12) will define the matrix referred to above, and the cubic voids (12) will serve to provide the optimum resolution of stress which minimizes the development of tension in the material. One in four of the hypothetical or mathematical RDs can be eliminated achieving the same force resolution result in a structure that contains less material. The shape and size, but not the position, of the voids (12) can be varied with only slight loss in optimum stress resolution. Some voids (12) can be omitted with only slight loss of optimum stress resolution.

Abstract: A simple joining process for members of passive microwave structures is described which reduces passive intermodulation. The process forms an aperture (28) in a first member (22) and forms a second member (24) to have dimension which exceeds the aperture dimension by a dimension differential. The members are joined by initially causing them to have a temperature differential that is sufficient to permit the second member to be positioned across the aperture. The dimension differential is selected to generate mutually-induced radial stresses in the members, after the temperature differential is removed, which enhance the metal-to-metal contact between the members and, thereby, improve passive intermodulation (PIM) performance. Preferably, the dimension differential is selected to cause the second member to elastically buckle and exert a buckling stress against the first member. Additional interface structures are provided to resist operational axial forces, e.g., vibration, that tend to dislodge the members.

Abstract: A system for enhancing steam distribution in a thermal stimulation phase, and for reducing the production of particulate matter with hydrocarbon fluids in a production phase, has a base pipe with a limited number of spaced-apart holes. The spaced-apart holes are sized and located so that steam is uniformly distributed in the reservoir. A collar is disposed around each hole to deflect the steam into an annulus between the base pipe and a wire-wrap screen section to avoid erosion and deterioration of the wire-wrap screen, which is required in the production phase. Mobilized hydrocarbon fluids flow to the wire-wrap screen section, which acts to filter particulate matter so that the production of particulate matter with hydrocarbon fluid is limited. The open area in the base pipe is significantly reduced, as compared with conventional methods, so that at the design injection rates, the pressure drop through the spaced-apart holes is larger than the pressure drop along the base pipe. During hydrocarbon fluid production, the pressure drop from the reservoir to the spaced-apart holes is low due to the presence of the wire-wrap screens. The open area in the base pipe while significantly reduced at the design production rates, as compared with conventional methods, should not unduly limit production rates.
