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: 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.
