Abstract: End bearing assemblies are provided for articulating links, especially for articulating control links associated with helicopter rotor mechanisms. The end bearing assemblies comprise at least two elastomeric bearing sections connected by a load-transmitting member and arranged to react to loadings and accommodate motions along and about at least one of three mutually orthogonal axes.

Abstract: A storage cabinet is provided which comprises at least one pull-out frame with a book support for supporting books so that they can be opened and read without removing them from the frame. The book support is in the form of a hanger bar from which the books are hung for storage. The hanger bar is adapted to permit the books to be easily pivoted up into a reading or use position and also to permit the books to be removed easily if pivoted to a selected book-releasing position.

Abstract: A flexible coupling comprises first and second torque transmitting members capable of being rotated about first and second axes, respectively. The coupling also includes connecting members associated in pairs. The connecting members are connected together and to the torque transmitting members through suitable bearings, preferably of the elastomeric type, for carrying pure compressive stress loading for torque transmission and for providing shear motion and restoring forces when said axes become misaligned.

Abstract: A machine that quadrates documents comprising a stationary plate having along one edge a plurality of transversely-spaced cutting edges defining a cutting area, a rotor having axially thereof and radially-spaced from its axis a plurality of complementary cutting edges supported for rotation with the rotor about an axis parallel to the edge of the stationary plate for movement of the cutting edges in shearing relation to the cutting edges on the stationary plate and sheet-feeding rolls for advancing the documents to be quadrated along the surface of the stationary plate onto the cutting area to present a portion thereof to the cutting edges in timed relation to movement of the cutting edges into cutting relation with each other.

Abstract: A snubber apparatus having a pair of elements telescopically interconnected for relative movement with respect to each other through a ball nut or lead screw device, a braking surface on one of the elements, an inertia mass driven by the other of the elements, a support for the brake shoe and a lever coupled to the inertia mass and pivotally coupled to the support for urging the shoe against the braking surface.

Abstract: A novel loose-leaf holder is provided for binding documents such as multi-leaf computer printouts and mounting the same in a suspension-filing and/or storing system. The holder is of the type described in U.S. Pat. No. 4,056,296 and comprises a plastic body which is molded as an integral unit and comprises two side sections which are connected together by a hinge section so that they can be swung toward and away from one another. The improvement comprises document mounting pins carried by one side section and engageable by the other side section, one or more of the pins being adjustbly mounted on the one side and movable toward and away from the other pins. Manually releasable locking means are provided for locking the two side sections together so as to captivate documents which are mounted on the pins.

Abstract: A screw having its head shaped to prevent its removal by unauthorized persons, characterized in that it has peripherally thereof an odd number of sides arranged symmetrically with respect to the center of the head and inclined to the axis of the screw to prevent removal of the screw by the use of pliers. The screw is removed by the use of a matching socket wrench.

Abstract: A record keeping system comprises (1) a multiple sheet assembly including a label with an adhesive backing and registration means including an adhesive backed flap and (2) a master ledger sheet for recording a plurality of entries. The multiple sheet assembly is used with the master ledger sheet by securing the flap of the assembly to the back of the master ledger sheet in proper registration so that information provided on the label assembly will simultaneously be transferred to the master ledger sheet.

Abstract: Apparatus is disclosed for supporting a document-holding cartridge in a position that permits the documents to be read easily. The cartridge is held on its spine in a position reversed from its normal document-supporting position and means are provided to keep it from tipping sideways by appropriately engaging one of the cartridge hooks by which the cartridge is held in its normal upright position.

Abstract: A novel stand is provided for supporting reference manuals of the type comprising a loose leaf holder with a hook located intermediate its end. The stand features means for preventing the holders from moving side-to-side and means adapted to interlock with the hooks of the holders to secure the latter in place. As added features, a key-operated locking device may be provided to prevent removal of the holders from the stand and two wire "flyleafs" may be attached to the stand to support the pages of the attached manuals when they are opened.

Abstract: Fluidic vibration isolation system which includes an isolator having a chamber, liquid and the vapor of the liquid in said chamber, heater means for heating the liquid and regulating means for controlling the heater depending upon the isolator relative height.

Abstract: A novel loose-leaf holder is provided for binding documents such as a multi-leaf computer printout and mounting the same in a suspension-filing and/or storing system. The holder comprises a plastic body which is molded as an integral unit and comprises two side sections which are connected together by a hinge section so that they can be swung toward and away from one another, and document mounting posts carried by one side section and engageable by the other side section. Manually releasable locking means are provided for locking the two side sections together so as to captivate documents which are mounted on the binding posts.

Abstract: A snubber apparatus which is constructed to present a high resistance to acceleration of the end fittings with respect to each other such as might occur due to seismic motion. The snubber apparatus preferably comprises a device which converts linear to rotary motion such as a ball screw and ball nut assembly which drives an inertia mass through a brake set and which when rotating causes braking to occur to increase the resistance force on the ball screw and ball nut assembly thus translating rotational resistance to linear resistance. The snubber apparatus is useful in restraining power plant piping, etc., in locations where earthquakes would be expected to occur.

Abstract: A cabinet is provided which comprises a pull-out shelf, means for supporting books on the shelf so that they can be opened and read without removing them from the shelf, and means for automatically closing the books at the ends of the shelf when the shelf is pushed back into the cabinet.

Abstract: A self-positioning shock and vibration isolating suspension system is disclosed which incorporates one or more pneumatic mounts for supporting a load on a base. Each pneumatic mount comprises a hollow elastomer body with a diaphragm at each end, means for connecting one diaphragm to a base and the other to the load, means for pressurizing the elastomer body with a fluid so that the diaphragms and the fluid acting thereon form a pneumatic spring having a spring stiffness less than that of the hollow body, and means for varying the fluid pressure within the elastomer body in accordance with changes in the magnitude of the load.

Abstract: A one-piece spring fastener for connecting two members is disclosed which is useful as a replacement for a spring-biased hinge. The fastener has a body section with spring clips and a tab for locking the body section to one member and a leaf spring section that projects from one side of the body section and has means for attaching it to a second member.

Abstract: An improved air nozzle is provided which produces high thrust amplification over a relatively wide range of input flow rates while maintaining relatively low noise levels. The nozzle is adapted to provide flow amplification by inducing flow of ambient air with high pressure air.
