Abstract: A combination card dealing shoe and protective guard plate is disclosed. An improved card follower device is also included for more effective control of the cards when the shoe is in use. The guard plate may be formed integrally with the shoe or it may be fabricated as a separate item for retrofitting attachment to an existing shoe. The plate is bifurcated and the two parts are joined by a hinge with a coil spring which urges the lower portion of the cover plate downward and inward to substantially cover the finger opening in the front panel of the shoe to conceal the card which is in position ready for dealing. The hinged portion of the cover plate has a projecting member defining an opening which is sufficient to give the dealer's thumb and/or finger access to the shoe without exposing the card that is being dealt, thus preventing one type of cheating by a dealer.
Abstract: A passive caging system for use in gyro-stabilized sensor platforms and the like, employing a pneumatic dashpot in place of automatic caging gyro brakes, pin-locking devices, springs, fluid damped pistons, or air bladders. A pneumatic dashpot in combination with a normally closed solenoid valve provides effective damping of shock forces while the system is in the unpowered state. When power is applied to the system, the solenoid valve is open and unrestricted movement of the sensor platform is enabled.
Abstract: A decorative and durable vehicle license plate cover is a flat, rigid, relatively thick, mar-resistant plate of optically transparent stable plastic, such as acrylic plastic. The plate has a solid body, with a front surface, a rear surface and sides interconnecting the front and rear surfaces. At least one and preferably all of the sides slope at about 30-60 degrees forwardly from the larger area rear surface to the smaller area front surface. The sloped sides are smooth and light reflective to enhance the appearance of the cover. Spaced holes are drilled or otherwise formed in the perimeter of the front surface and extend to the rear surface for attaching the cover to a vehicle license plate. The plate includes at least one of laser etching or engraving and printed indicia. The laser etching is disposed on the front and/or rear surface and/or interior of the plate.
Abstract: Apparatus for holding a book or the like with its pages in an open position to permit viewing the displayed pages. The page holding assemblies on right and left sides of the book have rotatable members which facilitate the turning of a page from one side to the other without disrupting the function of holding the other pages of the open book in place.
Abstract: A chewing gum stick dispenser includes a generally box-shaped container having a slot therein for dispensing a single stick of gum. A scissoring pair of swing arms utilizes tensioning means for urging the contained sticks of gum toward an operator wall. The operator wall retains a slidable operator having a seat adapted to engage a single stick of gum and push it partially through the dispensing slot. The container further includes a pivoted cap which can be opened to provide easy refilling of the container.
Abstract: A seal mechanism for conveniently coupling bayonet-type connectors while providing stable compression of the seal therebetween. The mechanism enables a more rigid configuration providing increased resistance to deformation from lateral forces. The mechanism incorporates an internally threaded coupling nut support element which cooperates with a threaded flange projecting from the plug sleeve to maintain a hermetic seal under conditions applying lateral forces to the connection. Interaction between the support element and the threaded flange permit the support element to be installed onto or removed from the connector assembly.
Abstract: A coaxial cable structure incorporating a physical interruption in the outer jacket or sheath of the cable. This interrupts the continuity of the outer conductor and serves to block DC (direct current) and low frequency electrical signals. Also, it greatly reduces heat transmission along the cable. The interruption is achieved by placing a specially fabricated stub in series with the coaxial cable. The resulting coaxial cable assembly acts like a band-pass filter which, although blocking DC and lower frequency electrical signals, is able to transmit RF (radio frequency) signals at selected frequencies. The entire assembly, including the stub, can be made hermetic.
Abstract: Pyrotechnic actuator cover/fin release system designed for high G forces of gun-launched-systems. As safety feature, system allows the pyrotechnic actuator to be installed as one of the last steps of the final testing sequence and removed safely on disassembly. A first cam action develops initial ejection. Subsequently firing the pyrotechnic pushes both the fins and the covers outward via a second cam surface. The release system both holds covers securely latched until commanded to release and then unlatches covers prior to pushing them open. The cover eject sequence results in the flight forward edge of cover being kicked into air stream. Thereafter the cover is lifted and rotates about its aft release hinge until, at about 30 degrees of rotation, the hinge disengages. The fins then are driven into the fully deployed state by a spring and piston/wedge mechanism on the actuator shaft.

A number of mounting arrangements for simplifying selection of the desired earphone angle are disclosed.
Abstract: An integrated system for missile steering, which uses both jet reaction control (JRC) and aerofin control systems, is provided with a variable coupling mechanism for adjusting the relative responsiveness of the two systems in accordance with the pressurization state of the JRC system pressure chamber. In one embodiment, the pivoting action of a joystick which actuates the gas flow control pintles of the JRC system is permitted only under sufficient pressurization of the pressure chamber. In a second embodiment, the extent to which the pintles protrude from their controllable housings is adjusted according to the pressure in the pressure chamber. In this manner, when JRC is undesirable or is unavailable, the missile aerofins are permitted their full range of motion without being constrained by the pintles.
Abstract: An adjustable tensioning arrangement for modular security door systems has modular components interchangeable for use on either side of the door system, thereby reducing significantly the number of parts which must be manufactured for the door. The adjustable tensioning arrangement is capable of accommodating a variety of tensions desired by individual users. The adjustable tensioning arrangement may be produced with a minimal number of required parts, and at very low cost. Construction of the adjustable tensioning arrangement may incorporate readily fabricated steel components, or utilize injection molded or other plastic type materials.
Abstract: An endodontic system of shaping instruments, irrigation cannulas, filling instruments and materials designed to safely create specific tapers of root canal preparations and to clean, dry, seal, and restore them. The shaping instruments are a series of reamers, files, and handpiece burs, made of stainless steel, nickel-titanium, or other alloys, which impart several different specifically-tapered apertures in root canals. The instruments have one or more safety features to eliminate perforating curved roots, including shorter flute length as the angle of taper increases and variable sharpness along the length of the flute portion, as well as variable flute pitch along the length of the flute portion to maximize cutting efficiency and resistance to breakage, and a rounded tip to eliminate ledging. The hand instruments have a handle designed to optimize use of the instruments in apically directed, notary cutting motions.
