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.

Abstract: A pin hole type star globe of a planetarium is provided with star identifying means for intermittently interrupting light projected through a pin hole of the star globe to form a star image on a viewing screen, thereby causing a perceptible, identifying blinking of said star image. The star identifying means includes an occluding arm which may be caused to swing back and forth into and out of interference with reference to the projected light; such swinging being caused by electrical, radio frequency means, controlled by step operating switching means.

Abstract: One or both opposite side portions of an edge of a workpiece of sheet material are peened to smoothness by two coacting peening tools in the form of collars oppositely acting upon said side portions through coaction with a rotary hammer resiliently carried within a housing. The two collars are slidably and rotatively carried on a stem rigidly depending from the housing and are held on the stem by an adjustable nut at the bottom of the stem. A first one of said collars is vibratorily actuated through direct action of said hammer to peen one of said side edge portions of the workpiece while the other of said collars is actuated indirectly to support and/or peen the other of said side edge portions through vibratory reaction of the hammer to its direct actuation of the first collar, which reaction is effective through said housing and its said stem.

Abstract: A pulley arrangement is operable by a person located adjacent to a table to lower a food holding container into a refrigerated well in the table and to raise said container with respect to said well sufficiently to render the contents of the container readily accessible to said person.

Abstract: A single punch head is slidable along a multi-faced, rotatable, horizontal bar having different arrays of detents on its several faces; a spring-pressed ball coacting successively with the detents on any selected face of the bar to position the head for punching holes spaced correspondingly to the detent spacing on the selected face. The ball also serves to hold the bar somewhat yieldably in any of the plural face positions to which the bar may be turned.

Abstract: A relatively rigid linch pin having a portion of serpentine shape extending loosely through a transverse bore in a bolt, serves to oppose sliding of a collar or the like from the bolt; the serpentine character of said portion of the linch pin permitting easy sliding of said pin into said bore while opposing dislodgment of the linch pin from the bolt.

Abstract: An inverted, manually operable, cylindrical, inverted-cup-shaped valve element is turnable axially back and forth between an open position in which an aperture in said element's side wall registers with a fluid passage of a fixed central core of the valve and an opening in the housing of the valve to permit fluid to flow therethrough and a closed position in which a non-apertured portion of said element's side wall registers with the valve's said fluid passage and said opening to close said passage against flow of fluid therethrough. An operating knob is provided for manually turning said valve element, and means are provided for limiting the turning of said valve element to considerably less than a full turn.

Abstract: A drive shaft for turning wheels of a vehicle or for operating other devices requiring rotary driving motion, has a pair of diametrically opposed compressors non-rotatively mounted upon it and also a dual channeled turbine mounted upon it with a rotor of the turbine keyed to the drive shaft to cause said shaft to turn with said rotor; separate duct means being provided between the two compressors and diametrically opposite points of the turbine's two channels for conducting ignited gas from the compressors to the turbine to drive said rotor and the drive shaft. Each compressor includes a piston, gas intake and exhaust valves, and means for igniting compressed gas in the compressor to charge the ignited gas into the turbine.
