Abstract: The feed tube for the gun has an inlet with an outlet transverse to the inlet and which is adapted to be coupled to the ball inlet of the gun barrel. The feed robe wall opposite the outlet effectively is closed. The feed tube also has a gas outlet in the feed tube opposite its outlet for directing gas toward the feed tube outlet for enhancing movement of a ball in the feed tube out of its outlet into the gun barrel.

Abstract: A jewelry box has plural racks, plural covers and retaining bands. Each rack has a board with openings formed therethrough. The openings receive jewelry. A variety of opening sizes are provided. Each rack also has a standoff wall projecting out in front and in back of the board. The racks are pivotally coupled together with hinges in an accordion manner so as to allow the opening and closing of the box by opening and closing the racks. The standoff walls provide gaps between the boards when the box is closed. The covers cover the endmost racks. The covers have projections for receiving the retaining bands, which maintain the box in a closed condition.

Abstract: A tubular body supports an insulator member at its front end which carries a center contact. An electrical lead is connected to the center contact and extends through the tubular body rearward and out of the apparatus. The insulator member and support structure supports a shell or wall spaced from and surrounding the tubular body with an opening facing rearward. A plurality of angularly spaced apart latch openings extend through the shell. A plurality of latches are pivotally supported to the front portion of the tubular body for movement through the latch openings. A sleeve with a cam movable between forward and rearward latching and unlatching positions is located around the tubular body. In the forward position of the sleeve, the cam and a spring move the latches outward through the latch openings and in the rearward position of the sleeve the latches are moved inward through the latch openings. An electrical lead is electrically coupled to the latches by way of the tubular body.

Abstract: The test apparatus of the present invention tests the power supply on a military aircraft, which power supply provides power to missiles carried by the aircraft. The apparatus tests for an overvoltage condition, wherein the power supply output exceeds the maximum allowable voltage of the missiles. The test apparatus includes an electrical connector for interfacing the test apparatus with the aircraft power supply, and an electrical comparator that compares the voltages from first and second inputs. The first input is clamped to a voltage which is representative of the maximum voltage limit of the missiles and the second input is tied to the output of the aircraft power supply so as to vary with the power supply output. The comparator activates a warning lamp when the second input voltage exceeds the first input voltage to warn an operator of an overvoltage condition.

Abstract: A solenoid has a coil with an outer core and an inner core. The cores provide the magnetic circuit around the coil. The inner core includes a rotor which has radially extending armatures. The armatures are positioned in gaps between radially extending poles of the outer core so as to form air gaps between the poles and the armatures. When the coil is energized, the armatures are attracted to the poles and cause the rotor to rotate, thereby closing the air gaps. The shaft is coupled to the rotor through a drive mechanism so as to rotate with the rotor. The shaft is made of a material with a relatively high magnetic permeability, as are the inner and outer cores, so that the shaft is magnetically coupled to the inner core rotor. When the rotor stops rotating, the shaft also stops. A return spring returns the rotor to its deenergized position when the coil is deenergized, recreating the air gaps. The drive mechanism allows the shaft to remain stationary while the rotors return to the deenergized position.

Abstract: The test probe has a tubular body member with a fixed sleeve secured to its front end such that an annular space is formed between the tubular body member and the fixed sleeve rearward of the forward portion of the test probe. A plurality of forward apertures are formed through the fixed sleeve in a plane transverse to the axis of the tubular body member and a plurality of rearward apertures are formed through the fixed sleeve in a second plane transverse to the axis of the tubular body member. A slideable sleeve is located around the tubular body member and is adapted to be moved to rearward and forward positions in the annular space relative to the tubular body member. Centering balls are located partially in the forward apertures and partially in the annular space and latching balls are located partially in the rearward apertures and partially in the annular space.

Abstract: A current potential indicator for connection with electrical contacts for detecting with a minimum event indicator the presence of a minimum electrical energy potential available at the contacts, and a threshold indicator for sensing a selected quantity of electrical energy above said minimum energy level. The apparatus is specially adapted for insertion into a pyrotechnic cartridge well or breech cap of a weapons system using pyrotechnically discharged weapons by utilizing a housing with retainer means for releasable connection with the well or breech cap. No electrical power supply is required for operation of this current potential indicator, thus producing essentially fail sale reliability.
