The compression device can serve as a splint for broken bones, as a pressure dressing for the control of bleeding, or as a treatment device for minimizing the effect of snake venom or a snake bite victim.

Abstract: An optical transducer for determining the angular position of a rotating member relative to a fixed structure, comprises a notched disc 13 rotatable inside a support housing 12, a light emitter 18 and a plurality of photovoltaic cells 19 for detecting the passage of light through the disc notches. The active and passive elements of an electronic circuit connected to the photovoltaic cells are carried by a single ceramic plate 21, which also acts as a support for the cells 19. The circuit comprises trimming resistors in the form of films deposited on the ceramic plate and connected to the amplifiers by the photovoltaic cells. In order for the signals generated by the amplifiers to have constant, predetermined peak values, the values of the resistors are trimmed during the production stage by means of a laser which selectively burns away parts thereof. The ceramic plate 21 is cemented on to the transducer housing 12, which is then positioned on the laser apparatus.

Abstract: In a typewriter a carriage spacing mechanism is mounted on a support element to space a paper bearing carriage independently from a base structure and is connectable for assembly of the machine to a control means supported by the base structure. Keys, intermediate levers and type basket are assembled independently from the base structure and are fixed to the base structure only through the medium of a supporting block for the keys and fixing means for the type basket. A plate picks up the striking movement of the type bars and comprises a plurality of bearing elements disposed so as to cause the plate to rock about two pivot elements of the bearing elements and a cam portion which is dimensioned so as to regularize the stroke of a transmission element in dependence upon the particular type bar actuated for the striking.

Abstract: A cardiac prosthesis having a hydraulically actuated compressible blood pump. An actuation chamber adjacent the blood pump receives hydraulic actuation fluid from an actuator pump through a three-way ventricular dump valve to compress the blood pump during systole and eject blood therefrom. During diastole the actuation fluid is permitted to drain from the actuation chamber through the three-way valve into a reservoir. The valve includes inlet and outlet manifolds and synchronously movable valve members within each manifold for controlling the flow of actuation fluid into and out of the actuation chamber.

Abstract: Methods and apparatus for splitting substantially straight grained lignocellulosic material substantially along grain lines into slabs are provided. The apparatus may comprise: means for advancing material along a direction of travel, a plurality of splitter blades, said blades being spaced along the direction of travel, and being laterally spaced apart in a stepped row from a first splitter blade located to commence splitting at one side of the material, to a last splitter blade located to finalize splitting at the opposite side of the material, and support means to support the material when advancing the material in the direction of travel and past said splitter blades, said apparatus permitting the split slabs to separate away from the remainder of said material.

Abstract: A container suitable for fruit and vegetable produce has a lid with a multipoint friction lock for retaining the lid closed on the container body provided by a stacking tab projecting from the perimeter of the body opening having undercut side edges and an aperture facing toward such opening while the lid has a notch located for the stacking tab to engage therein when the lid is closed, the ends of such notch being spaced to engage beneath the undercut side edges of the stacking tab and the notch providing a locking portion intermediate such notch ends to engage in the stacking tab aperture in the closed position of the lid. Preferably, the material of the lid is diagonally scored to facilitate bending the lid for interengagement of the stacking tab and notch, and to accommodate moderate overfilling of the container.

Abstract: Graphics such as isometric engineering drawings needed for piping fabrication and installation in the construction of an industrial plant are generated by building a physical miniaturized design model of the plant, applying visually exposed indicia to separate segments on the model with this indicia for each segment being identifiably descriptive of the distinguishing characteristics of such segment as it is to exist in the final industrial plant after its construction, and optically scanning the exposed indicia on the design model to thereby collectively record the scanned information on an electronic storage memory. The recorded information is then integrated by utilizing a general purpose computer with a compatible computer program and the combined result is supplied as electronic plotting signals to a graphics plotter to produce the graphics for use thereafter in construction of the full size industrial plant.
