Abstract: A radio frequency switch assembly (120) is mountable between an antenna port (110) and a detachable antenna (130) of a radio communication device assembly (100) to provide an interface for a radio frequency accessory. The switch assembly (120) has a radio interface port (123), a radio frequency accessory port (125), and an antenna interface port (127), and associated contacts (207, 216, 223). A mechanical switch alternatively interconnects the radio interface port (123) with the radio frequency accessory port (125) or with the antenna interface port (127). Preferably, the switch includes a conductive probe (213) that continuously engages the radio interface port contact (207) while being slidable to electrically interconnect with the antenna interface port contact (223) or with the radio frequency accessory port contact (216).

Abstract: A radio housing (101) includes first and second retention mechanisms (216, 218) on both its back and bottom surfaces (104, 106) for selectively retaining a variety of battery form factors and providing a variety of radio configurations.

Abstract: A simulator handgrip is connected to the shaft of a slip clutch which offers resistance to handgrip displacement, thereby simulating the "feel" of an actual thrust control for aircraft. Linkages are provided for measuring the amount of handgrip displacement as an electrical signal that may be utilized by a simulator computer. Adjustment devices are provided for moving the handgrip and clutch devices along a diagonal direction to accommodate pilots of different height.

Abstract: A sidestick grip is slidably mounted to achieve adjustable fore-aft displacement. Separate spring devices are linked to the grip for simulating break-out force and force-deflection characteristics. Each spring device is linked to a damper for damping grip movement in the pitch and roll directions. The spring devices have (1) variable spring pre-load bias thereby enabling adjustments of the breakout forces; and (2) adjustable stick neutral position. Transducers measure grip deflection in roll and pitch for utilization by a computer.

Abstract: A folding machine having a horizontally elongated input plate with front and rear horizontal edges, a mechanism including input wheels disposed at the rear edge, the mechanism having a first position at which the wheels are disposed above the plate and a second position at which the wheels are lowered to said plate, a horizontally elongated roller rotatable about its own axis and disposed at the rear edge, the wheels being engaged with the roller when the mechanism is in the second position and a motor for rotating the roller. The machine also includes first and second spaced apart photoelectric circuits, each circuit producing a vertical light beam, which, when not interrupted, passes the rear edge, said beams defining a vertical plane, as well as a third photoelectric circuit producing a horizontal light beam which, when not interrupted, passes horizontally along the rear edge parallel to said plane.

Abstract: An apparatus for making cushioning, shock absorbing, insulating or packaging material formed of webs of plastic material sealed together to make fluid or air filled cells in a quilted fashion. A tube forming roller forms tubes of the material. Heat sealing elements seal the webs into tubular formation and additional heat sealing elements seal the webs transversely across the tubular formation to form a series of cells. A fluid blower maintains fluid or air within the tubes during the cellular formation.

Abstract: An apparatus for the fabrication of battery separator sleeves in which two sheets of microporous plastic material are bonded to intermediately-disposed sealing strips by solvent welding or solvent adhesive bonding. Dispensers continuously apply solvent or solvent adhesive to the interfaces between continuous lengths of parallel, superposed sheet material and two, continuous lengths of sealing strips disposed between and along the lateral edges of the sheet materials. Bonding is achieved by subjecting the assembled materials to pressure applied by a series of pressure rollers and to heat applied to the lateral edges of the sheet materials by heating elements. The continuous length of formed battery separator sleeve is cut to the appropriate length.
