  • Patent number: 6134725
    Abstract: A method of moving a person to a standing position from a seated position on a seat including the steps of providing an attachment member for engagement with the person, moving the person who is connected to the attachment member slightly upwardly and thereafter in an essentially horizontal direction, and thereafter moving the person in an essentially vertical direction to a standing position, returning the person from a standing position to the seated position by moving the person essentially horizontally to above the seat, and then moving the person essentially vertically onto the seat. The method also includes steps of counting or recording the number of times the person has been moved from one to the other of the seated and standing positions, and storing the identity of the person that has been so moved.

  • Patent number: 3978730
    Abstract: An altimeter has a rotatably-mounted index that is driven to rotate through one complete revolution around a scale for each change of 1,000 feet in altitude sensed by two evacuated manometric capsules the number of revolutions of the index is indicated by numerical markings visible through an arcuate window which breaks into the scale against a `zero` arrowhead at the top-center of the scale. The markings are distributed around the opaque circumferential-margin of a transparent disc that is mounted coaxially with the index and is driven in the counter direction to the index through step-down gearing. Successive ones of the numerical markings are rotated to the zero arrowhead to indicate the number of units of 1,000 feet appropriate to the altitude measurement, upon successive revolutions of the index.

  • Patent number: 3977015
    Abstract: A semiconductor transferred electron device of the kind which includes indium phosphide as a major constituent is provided with a cathode consisting of oxidized silver gallium. The cathode preferably contains 4 times more silver than gallium by weight, and the oxygen content is preferably from 2 to 20 atomic per cent of the gallium content of the cathode. This improved device provides high electrical to microwave conversion efficiencies for a high proportion of devices produced together in any given batch.

  • Patent number: 3976392
    Abstract: A circulation pump having a comparatively slender drive shaft is provided with an improved axial sealing arrangement to prevent the leakage of circulating liquid through the bore in the pump housing wall in which the drive shaft is supported. The sealing arrangement comprises a pair of bushing-like bodies disposed around the drive shaft between the drive shaft and the wall of the bore, and a pair of pressure elements disposed around the drive shaft and movable in the direction of the shaft abut the sealing elements and are pressed into engagement with the sealing elements by spring means located outside the bore.

  • Patent number: 3975697
    Abstract: A surface acoustic wave device comprises a substrate able to support surface acoustic waves, an input transducer for launching surface acoustic waves along a first track on the substrate, an output transducer for receiving surface acoustic waves from a second track on the substrate, and first and second reflective array structures arranged to reflect surface acoustic waves from the first track into the second track, the first and second reflective array structures each comprising numerous reflecting strips or grooves arranged parallel to one another in echalon across the first and second tracks respectively. Varying the lengths of the reflecting elements provides weighting of signals passing through the device, and varying the spacing between the reflecting elements provides pulse compression or expansion with a frequency sweep.

  • Patent number: 3971550
    Abstract: An elastic eye-bush is provided for use in combination with the eyeend of an automobile leaf spring, etc. for absorption of radially applied shock loads. The bush has its intermediate portion diametrically reduced so as to provide a space between the eyeend and the intermediate portion, which portion is made up of co-centrically stratified layers of different hardness. The eye-bush offers an improved damping characteristic exhibiting a low spring constant under smaller loads and a high one under larger loads.
