  • Patent number: 4343508
    Abstract: A latch mechanism (24) disclosed secures a vehicle seat (10) in a seating position and is selectively releasable to permit movement of cushion, back, and auxliary components (14, 16, 18) on a support linkage (20) to a bed position. The latch mechanism includes a first latch (26) having a latched position for securing the cushion and back components (14, 16) in the seating position. A second latch (28) of the mechanism has a latched position for securing the auxiliary component (18) in a vertical seating position at the rear of the back component. A pair of the first latches are preferably provided at opposite lateral sides of the seat with the second latch therebetween and are releasable in coordination therewith by an actuator (30) of the mechanism to permit unlatching that allows the seat movement to the bed position. A laterally extending connector shaft (96) of the actuator coordinates the releasing of the latches and is pivotally moved by a pedal-actuated member through a pair of cams.

  • Patent number: 4340635
    Abstract: In accordance with the invention there is provided a sintered monolithic ceramic substrate for fine-line electrical circuitry, the substrate comprising a base layer containing at least 90% by weight crystalline alumina or beryllia and a thin upper layer containing at least 90% by weight crystalline material the same as that of the base layer but with an average grain size less than that of the crystalline material of the base layer, the upper layer having an irregular interface with the base layer but a planar upper surface with minimal surface irregularities for improved reception of the fine-line circuitry to be applied. Further in accordance with the invention such substrate is made by first forming and firing a ceramic plate of alumina or beryllia ceramic to provide the base layer and then applying and firing a coating of fine grain alumina or beryllia, as the case may be, on the plate to provide the upper layer.

  • Patent number: 4337739
    Abstract: An internal combustion engine valve deactivator mechanism including a pair of reciprocable cylindrical members and a movable piston therein which together function as a normal tappet when pressurized fluid is fed to a chamber defined between the piston and a first cylindrical member but when the pressurized fluid is exhausted from the chamber the engine valves of the engine remain seated by their respective valve springs while the two cylindrical members are allowed to reciprocate with respect to each other by the piston. Engine oil pressure may be used as the operating fluid for the valve deactivator. An inlet passage formed in the cylinder block feeds pressurized fluid to the chamber in a first position of a control valve located within the cylinder block to move the piston away from the first member to prevent the second member from reciprocating with respect to the first member and thereby enable normal operation of an engine cylinder intake or exhaust valve by its pushrod.

  • Patent number: 4326445
    Abstract: An armored underbody for a road vehicle is disclosed as including fabricated armor plate to protect both the vehicle underbody components and the vehicle occupant compartment from projectiles such as deflected bullets or shrapnel. A plurality of armor protection plates (16, 18, 20 and 21) of the underbody provide radiator, engine, transmission, and transfer case protection from upwardly directed projectiles. The vehicle occupant compartment floor (22) includes front and rear floor sections (24, 26) of armor plate preferably connected by a laterally extending floor support member (60). A fuel tank (28) of the underbody has a fabricated armor plate construction that prevents puncturing thereof by projectiles. In its preferred construction, the underbody includes a pair of longitudinal frame members (30) spaced laterally from each other and connected by cross frame members (32, 34, 36, 38) that are used to mount the armor protection plates.

  • Patent number: 4324431
    Abstract: A vehicle seat having a seat portion, a support frame for the seat portion, a back rest portion and an independently adjustable, front thigh support slidably supported at the front of the seat portion. A pair of spaced slideways define a slide path for the thigh support extending from a fully retracted position to a fully extended position. In a first embodiment of the invention, the slide path is inclined upwardly in a forward direction at an angle which is sufficiently small enough that the sliding friction between the slideways and corresponding slide members of the thigh support prevents the weight of the thighs of a person sitting in a seat from moving the thigh support in a retracting direction. In a second embodiment of the invention, the slide path lies in an upwardly extending curved surface.

  • Patent number: 4324545
    Abstract: A recirculating processing oven heater (10) disclosed includes first and second flow paths (22,26) with an internal heat exchanger (36) located downstream from a burner (24) and upstream from a conical mixing member (28) that deflects gas from the first path outwardly for mixing with bypass gas that flows along the second path. Thermal incineration of unburned combustible gases takes place along the first path (22) after heating thereof by the burner and prior to passage thereof through the internal heat exchanger (36). Heat extracted by the internal heat exchanger (36) is supplied to the upstream end of one of the flow paths (22,26), preferably the first flow path (22) so as to provide most efficient operation of the heater.
