Abstract: A cleaning device for a cassette-type tape recorder wherein a cassette shell (1) is provided with a longitudinally reciprocating bar (25) adjacent the edge of the shell normally aligned with the heads of the recorder in use, the reciprocating bar being provided with a number of cleaning pads (19) which contact and clean the heads and drive rollers in the tape recorder in a reciprocating manner. In the preferred form of the invention three cleaning pads (19) are provided to clean the erase head, the record/playback head, and the capstan and pinch roller respectively. 
     The bar is reciprocated by a cam drive (14, 15, 16) from a hub member (3) rotated by a drive spindle in the tape recorder. In the preferred form of the invention two hub members (3, 8) are provided, one being engaged with the forward take-up spindle and the other with the reverse take-up spindle of the tape recorder so that the cleaning device can operate either way up or in conjunction with an auto-reverse tape recorder regardless of the playing direction engaged.

Title: End plug for a fiber optic in-line splice case assembly
Inventor: ANDERTON JOHN J
IPC: G02B6/38
Filed: 1984-12-18
Abstract: An end plug has a pair of rounded surfaces (21) complementary to the interior of a splice case housing (3) and a pair of flat surfaces (22) to which torque bars (2) are fastened. The end plugs (1) exhibit two pairs of apertures (23, 24) extending in an axial direction the length of the end plugs (1). The larger diameter apertures (23) accommodate the coated glass fibers which may be surrounded by woven protective layers. In practice the protective layers are dressed back and away from the fibers, positioned in lateral cutout portions (25), and secured by a pair of tie-off screws (26). In addition, the fiber optic cable will be customarily provided with a reinforcing «wand» running the length of the cable. The wand may be comprised of a strand of steel, fiberglass, copper or other material of suitable tensile strength. The wands are to be dressed through smaller diameter apertures (24) and severed at the other side of the end plugs (1). A pair of fasteners (25) is provided each of the end plugs in order to secure the wands thereto. The fasteners are in the form of a pair of setscrews (27) that are threaded into bores extending generally radially from the rounded surface towards the interior of the end plugs.

Abstract: ® The invention relates to an electric circuit breaker with an improved undervoltage release device. 
     The undervoltage release device (410) includes a non-ferromagnetic tube (436), a trip plunger (418) and a reset plunger (416) both of ferromagnetic material and disposed in the tube, an electric coil (414) for producing a magnetic holding force between the plungers which holds the trip plunger (418) inactive while the voltage across the coil remains normal, and a bias means (compression spring 424) which biases the reset plunger toward its lower position and becomes effective, when said voltage drops abnormally, to drive the trip plunger (418) to a trip position. The reset plunger (416) is manually operable (reset button 420) after each tripping movement of the trip plunger (418) to restore the latter to its home position, and is manually operable under normal voltage conditions to effect a tripping movement of the trip plunger for the purpose or manually tripping the circuit breaker.

Abstract: A device for indicating the presence of unacceptable levels of noncondensable gas, such as air, in a steam sterilization chamber. The device (10) includes an insulated heat sink (12) having an upper end (14) and a lower end (16). The upper end of the heat sink is in such open communication with the sterilization chamber that the steam enters the heat sink. The device also includes a chamber (34) proximate the lower end of the heat sink. The heat sink defines a path (18) through which the steam travels from the upper end toward the chamber. The path is adapted to provide sufficient exposure of the steam to the heat sink so that the steam condenses within the path, releasing any noncondensable gas associated with the steam and forcing it toward the chamber. The chamber includes means (40) for indicating the presence of noncondensable gas accumulated therein. The device also includes means such as the air in the chamber for preventing the condensate from affecting the indicating means.

Abstract: A valve stem position sensor (46) measures the stem position and a load sensor (48) measures the load on the valve stem (40) of a valve (25) operated by a motor (24) coupled to the stem (40) through a worm-shaft (42) and gears (44). A programmed microprocessor (32) periodically tests the status of the valve (25), and turns off the motor (24) if valve stem position and valve stem load criteria are not satisfied. The testing includes comparing the valve stem position with a preselected open position during opening; and comparing the valve stem load with a preselected maximum desirable stem opening load during opening, and with a preselected maximum desirable stem closing load during closing. During opening, the position of the valve stem at a predefined time in the future is predicted and the motor (24) turned off it is beyond a preselected position. During closing, the load on the valve stem at a predefined time in the future is predicted and the motor (24) turned off if it exceeds a preselected maximum load. Motor overload protection is provided by periodically measuring (70) the actual load on the motor (24): comparing the motor load with a preselected maximum value during opening and closing of the valve (25) and turning off the motor (24) if the measured motor load does not meet predefined criteria.
