Abstract: A support clip particularly adapted to removably support a first article, such as a holster, magazine pouch, badge or identification holder, canteens, and other equipment, relative to a second article, such as a belt or other article of apparel, comprises an integrally formed injection molded plastic body of generally U-shaped configuration, wherein first and second leg portions are resiliently interconnected by a connecting portion, the first leg portion is attached to the first article and the second leg portion carries a hook portion, which defines a concave surface arranged to face the connecting portion and has a free end portion normally biased into engagement with the first leg portion.

Abstract: A dispenser for controlling the dispensing of a liquid from a container, such as a bottle having an opening through which liquid may be poured, is provided in combination with a bladder insertable within the container and expansible incident to dispensing of liquid for occupying a volume corresponding to that of the dispensed liquid in order to prevent air contamination of any liquid remaining in the container. An improved bladder construction and method of forming same is disclosed.

Abstract: An open mouth receptacle adapted for mounting on a vertically disposed surface, such as a door or wall, is provided for receipt of articles, such as newspapers and packages, delivered to a residence. The receptacle is fabricated from flexible material and has its mouth bounded by facing strips of a relatively rigid and elastic material; the rigid strip assisting in the mounting of the receptacle and the elastic strip tending to normally retain the mouth of the receptacle in a closed condition.

Abstract: A panel of flexible but resilient material is supported on a post along a vertical axis in such a fashion that those portions of the panel extending beyond the post are permitted to flex under a given wind load.

Abstract: An improved low specific speed pump is disclosed, which provides for greater consistency of pump operating efficiencies obtainable by pumps of any given group of like size pumps. In the present pump, the internal dimensions of the pump chamber and discharge passage are enlarged to provide for a reduction in flow velocities therewithin compared to a conventional pump of a given design flow capacity and a controlled size restrictor is arranged adjacent the pump discharge in order to reduce the resultant increase in flow capacity to such given design value.

Abstract: An arm constraint particularly adapted for use as an aid in the self-feeding of a person afflicated with tremors. The constraint generally includes a base adapted for mounting on a suitable support, such as a table or hospital bedside tray; a forearm rest defining a forearm rest surface; means for supporting the forearm rest on the base for rotation about a first vertically disposed axis and for arranging the rest surface in a horizontally disposed position selectively vertically adjustable relative to the base; a hand rest; mounting means for connecting the hand rest to an end of the forearm rest for rotation relative thereto about a second horizontally disposed axis; a constraint for removably retaining a forearm in engagement with the rest surface with a hand arranged for overlying engagement with the hand rest; a plate supporting table; and mounting means for mounting the plate supporting table on the base to underlie the hand rest and for vertical adjustment relative thereto.

Abstract: A valve features a valve member adjustably fixed to a mounting member during assembly of the valve to provide for accurate repetitive seating of the valve member in fluid sealing engagement with a valve seat.

Abstract: The propeller shaft fairing is U-shaped in vertical section, and is partitioned to provide two separate sea chests from which water may be drawn for engine cooling purposes. The wall of the fairing in the region of the foremost sea chest is slot-wise apertured parallel to the propeller shaft and adjacent to the uprising side of the shaft when it is rotating to propel the craft forwardly, whereupon water is both rammed and pumped into the forward sea chest. The wall of the fairing in the region of the rearmost sea chest is apertured so that when the craft is moving in reverse water is rammed thereinto. Thus, under all conditions an adequate source of cooling water is available via at least one of the sea chests. The cooling water pump intake conduit includes separate branches drawing from the sea chests, and these branches are valve controlled automatically by means of the craft's operating control system.

Abstract: A mechanism for automatically winding a weight driven clock includes a common traveler member mounted for reciprocating movement between a rest and reversal position, a pulling member associated one with each weight of the clock and adapted to exert a pulling force on its supporting chain, a latch mechanism for each pulling member for selectively coupling same for movement with said traveler member, a weight sensing mechanism for sensing the arrival of each weight of the clock in a clock unwound position thereof for operating the latch mechanism of the pulling member associated with such weight and for initiating movement of the traveler member from its rest position, whereby a pulling force is exerted by the pulling member on the chain of its associated weight when placed in the unwound position thereof for lifting such weight into a clock wound position thereof coincident to the arrival of the traveler member in its reversal position, and a device for sensing the arrival of the traveler member in its revers

Abstract: A zoom lens system for optical instruments incorporates a crank and linkage mechanism which is adjustable to alter the conjugate length between at least a pair of zoom lens assemblies of the zoom lens system.

Abstract: A safety latch mechanism for use in connection with a pressure vessel of the type having a shell, a closure for removably closing an access opening defined by the shell and a locking ring rotatably supported by the shell adjacent the access opening for releasably locking the closure in access opening closed position. The mechanism features a first latch member mounted by the shell for releaseably preventing unlocking rotation of the locking ring relative to the shell and a second latch member mounted by the locking ring and responsive to movement of the first member for releasably preventing relative rotational movements of the locking ring and closure. The first member is operatively associated with a vessel exhaust valve, which tends to constrain unlatching movements of the first and second latch members, when the pressure within the vessel exceeds a safe level at which the closure may be operated without the possibility of injury to person or property.

Abstract: A straight line motion mechanism is formed from a pair of parallelogram linkage mechanisms in combination with motion control means interconnecting the linkage mechanisms to provide for uniform angular displacement thereof. The mechanism is particularly adapted for use in supporting an object, such as a table top, for vertically directed stepwise movement or one step shifting between lower and upper reference positions corresponding to table top heights convenient for use alternatively by a person in seated and standing positions. In a preferred embodiment, means are provided to enable a user to selectively make fine adjustments of the height of the table top after it has been shifted into either of such lower and upper reference positions.

Abstract: An expansion joint strip seal for use in roadways, bridges, buildings and the like to seal across a gap defined by a pair of parallel, elongated edge or frame members, which have generally C-shaped cavities opening towards the gap for purposes of supporting opposite lengthwise extending edges of the strip seal. The strip seal is formed of a suitable resiliently deformable material and defined by a web portion sized to span the gap and a pair of mounting bead portions joined to opposite edges of the web portion and adapted for insertion within the cavities of the edge members. Each mounting bead portion includes a solid or non-apertured main mounting portion, which is joined to the web portion and provided with a height essentially corresponding to the height of the cavity and a width less than the width of the cavity; and a tongue portion cantilever supported by the main mounting portion to project in a direction away from the web portion.
