Abstract: A device for simulating weapons firing by igniting various signature cartridges both singularly and in multiple burst sequences. A electronic timing source which provides the necessary control and impulses to perform said ignition. A unique cartridge design which provides safe and reliable performance.

Abstract: The cardiac patient support comprises a flat, rigid, horizontal base having an overlying torso support pivotally associated with a lower end area of said base and limitedly adjustable angularly upwardly in relation to the latter to effect and maintain a desired degree of suspension of a patient's head with reference to the patient's torso, with the patient's head extending beyond and clear of the upper end of the torso support. The disclosed means for effecting and maintaining such angular adjustment comprises a chin band and a forehead band, and a pair of manually operable screw knobs working on non-rotatable threaded studs adjacent to the upper end and opposite sides of the torso support. The screw knobs are freely turnable in bearing openings in the torso support. Also disclosed is an adjustable prop for elevating the torso support to hold the patient in a sitting posture; a novel, separable head rest being provided for use when the prop is being employed.

Abstract: A generally cylindrical, rotatable housing contains, against material axial shifting but with limited permissible lateral shifting, an approximately coaxial peening stem as a peening tool. An outer end of said tool, projecting from the housing, is formed with an encircling, continuous peening groove. The housing is formed with an uninterrupted circular series of inwardly facing projections within which the peening stem extends somewhat loosely. Upon rotation of the housing, forceful holding of a workpiece's metal edge in said groove while the workpiece is moved translationally, causes the peening tool to be rapidly hammered laterally, successively by the projections of said series; this hammering effect being transmitted by said tool to said metal edge whereby said edge is peened and deburred.

Abstract: The disclosed valve has a cylindrical, central, fluid conducting core fixed within a housing by a nut located in the housing in engagement with an integral flange of said core at the latter's inner end, an oscillatory valve element having a cylindrical wall, one end sleeve portion of which extends within a cylindrical space between the housing and the core to control fluid movement through the latter, and an opposite end sleeve portion of said cylindrical wall having an extremity formation in engagement with a knob for operating the valve, and said valve element being invertible during assembling or disassembling of the valve, in which inverted condition said extremity formation coacts with said nut to effect the latter's insertion or removal in the assembling or disassembling of the valve.

Abstract: The cardiac patient support comprises a flat base board of a size suitable for supporting a human patient and having an overlying torso supporting board pivotally associated with a bottom end area of the base board and extending angularly upwardly in relation to the latter, a transversely extending roller being mounted upon the base board in engagement with the under side of the torso supporting board and having operating means associated with said eccentric roller for adjustably turning the latter to urge the upper end of the torso supporting board upwardly and to lock said eccentric roller in an adjusted turned position. A handle is disclosed for turning the eccentric roller and a ratchet and pawl assembly is disclosed for locking the eccentric roller in an adjusted, turned position.

Abstract: The subject fuel injection means, disclosed herein with one of various types of internal combustion engines with which it may be employed, comprises a fuel pumping plunger, the pumping stroke of which is controlled by an inclined surface of a manually operable slide element. Said plunger is urged in a pumping direction by fluid pressure applied thereto from compression generated in the engine's combustion chamber and is spring biased in a non-pumping direction. A solenoid, operationally timed to the rotation of the engine's crankshaft, coacts with the pumping plunger to assure starting of the plunger's pumping stroke in proper timed relation to the compression and firing of an explosive charge in the engine's combustion chamber. In said pumping stroke, the plunger closes a fuel inlet to a related pump chamber and forces fuel from said pump chamber, past a one way check valve and into the engine's combustion chamber.

Abstract: A generally cylindrical, vertically vibrating peening tool has an integral, small diameter, cylindrical pilot at its lower end, adjoining a larger upper body portion of said tool at an annular juncture area having an outwardly concave surface at all circumferential points therearound. Supported below said peening tool is a resiliently yieldable anvil having a cylindrical top opening receptive of said pilot with a close sliding fit. The top of the anvil is flat and supports a workpiece between the tool and the anvil with a hole in the workpiece aligned with said pilot, enabling the latter to extend through said hole and into the anvil's said top opening. The workpiece is shiftable horizontally upon the anvil to enable all portions of the upper edge of said hole to be brought into peening, deburring engagement with said concave juncture area of the peening tool.

Abstract: A molded boat hull formed of bonded laminations of fiber glass sheet material is provided with longitudinally extending reinforcing stringers comprising substantially interleaved and interbonded marginal portions of plural laminations of fiber glass sheets of which the subject boat hull is generally constituted. The reinforcing stringers also serve to inseparably interconnect adjacent ones of the fiber glass sheets.
