A multiple switch in accordance with the present invention comprises a plurality of pushbuttons that are movable between an extended and a depressed position and are biased toward the extended position. The pushbuttons are paired and each pushbutton pair is associated with an individual lockout, a releasing-latching bar (RL bar) that is common to all of the pairs, and an individual releasing-nonlatching and releasing-latching bar (RNRL bar). Each pushbutton interacts with all three members when …

A hot gas engine of the Stirling type is disclosed. The engine has a heater head assembly provided with a plurality of separated regenerators connected in series in the heater tube labyrinth. The regenerators may be cascaded in size and mass to meet predetermined heat exchange design conditions. The temperature of exhaust gases exiting directly from the heater head assembly can be optimized at less than 800.degree.F, but more practically at about 1,000.degree.-1,200.degree.F.

A transducer system comprising, a multiple capacitive transducer having a flexible dielectric sheet of elastic nonconductive material, a first plate of flexible conductive material defining a region located adjacent a first surface of the sheet, and a plurality of second plates of flexible conductive material located adjacent a second surface of the sheet, with the second plates defining areas aligned with the region of the first plate. The system separately forms signals responsive to the capac…

A multiple hanger for garments such as blouses, shirts and the like, includes a plurality of generally parallel hanger elements on which the garments are hung. A connecting rod is pivotally connected to each of the hanger elements, and a guiding rod is pivotally connected to each of the hanger elements parallel to and spaced from the connecting rod to thereby provide a parallelogrammatic linkage such that the hangers are pivotal simultaneously in parallel array.

A multiple windmill in which three fan wheels are mounted on a common rotatable frame and are each rotatably linked to a common fixed wheel or gear. The fan wheels are each rotated by the force of the wind and in turn rotate the common frame in which they are mounted. The device may be in the form of a display device such as an ornamental lawn device, with the exterior of each fan blade marked so as to create ornamental patterns when the blades and the frame are rotated by the wind. The common s…

This invention can be used as an accessory to many different types of machines, mainly cut-off saws. It makes it possible to cut a quantity of material to different lengths in one operation per set-up, compared to one length per set-up in past inventions. The gauge operates by pushing the material to be cut alongside the guide bar, up to the desired stop. By pushing the material against the guide bar and side of the desired stop-pin, thus depressing the undesired stop-pins into the housing. The …

A multiple pipette has inside its body a piston mover rod which is provided with a push button at its upper end and surrounded by a spiral spring. Once the rod has been pressed downwardly, the spring returns the rod to its original position so that liquid is sucked into containers connected with the lower ends of the cylinders and provided with points. The rod can be pressed down again against the spring force for discharging the liquid from the containers.

The improved mattress of the present invention is adapted to sleep two or more people in side by side relation, each person being supported on resilient means defining a separate area of preselected firmness, the two areas being deposed lengthwise of the mattress in essentially parallel relation and being of different firmnesses. The mattress also includes resilient means defining an intermediate area between and integrally connecting the first two areas, and also disposed lengthwise of the matt…

The present invention is directed to a multiple compartment, multiple seal container particularly adapted for packaging plural portions of foods or the like. The device comprises a first container formed of polymeric material or the like and a second container adapted to nest within the first container. A lid member having a skirt extending into the second container provides a seal therefor. The lid and first container, and preferably also the second container, include flange portions disposed i…

A piezoelectric cone-type speaker having a multiple structure in which a plurality of piezoelectric elements and speaker diaphragms individually coupled to them are coaxially or multi-axially arranged. It has a wide frequency range. A cushioning member is interposed between one diaphragm and another so that each element is isolated from the vibrations of another element.
