Title: Mechanical fastening prong
Inventor: THOMAS DENNIS A
IPC: A44B18/00
Filed: 1990-01-31
Granted: 1998-04-16
Abstract: An improved releasably securable fastening system for attaching to a complementary receiving surface is disclosed. The fastening system features an engaging means in the form of a hook-shaped tine. The engaging means (30) is longitudinally spaced away from, or above, a substrate (24) by an upstanding shank (28). The engaging means (30) forms an included angle, relative to the perpendicular from the plane of the substrate, which is greater than 180 DEG  so that the engaging means (30) has a reentrant segment (31). The reentrant segment (31) of the engaging means provides for more effective securing of the fastening system to a receiving surface. An engaging means having an included angle greater than 180 DEG provides improved resistance to forces which cause separation of the engaging means from the receiving surface.

Title: Interrupter switch with coordination of disconnect and interrupt linkage
Inventor: ROGERS EDWARD J
IPC: H01H33/02
Filed: 1991-09-30
Granted: 1999-06-15
Abstract: An arrangement is provided that includes a coordinating input (e.g., via 62 to 64 to 54) for a mechanism (18) of an interrupter switch (10); the coordinating input being derived from sensed movement of an element (e.g., 32) away from a first position (FIGS. 3 and 4) and toward a second position (direction 67). The coordinating input is utilized to trip the interrupters if they are closed. In a specific arrangement, a stored-energy mechanism (18) is tripped to provide opening and closing of the interrupters via a high-speed interrupter drive train (20). The tripping arrangement (34) is operable via a first input (at 56 via 58,60) to cause movement of a latch member (40) to release the stored-energy mechanism (18) to operate the interrupter drive train (20). The first input may be actuated via open or close instructions, including both local and remote capabilities. The latch (40) for the stored-energy mechanism ( 18) is reset after each actuation. An output shaft (19) of the mechanism is connected to drive the interrupter drive train (20). Both opening and closing are accomplished via rotation of the output shaft (19) in the same direction. An open/close sensing input for the interrupter drive train (20) is derived from the position of the output shaft (19). In a specific embodiment, the sensed movement of the element (32) corresponds to the movement of a disconnect linkage (22) away from a closed position. <IMAGE>

Abstract: The sewage outlet comprises an upper member(1) having first and second strainers(11,12) and a lower member(2) whose upper portion is fitted to the lower outside periphery of the upper member. The sewage outlet is produced by the following processes of I) mixing 5-15 wt.% feldspar, 10-20 wt.% silica, 15-20 wt.% pottery stone, 15-25 wt.% agalmatolite, 3-5 wt.% limestone and 25-40 wt.% clay with water, II) forming the upper member and the lower member with the above mixture, III) primarily burning them in a kiln at 700-800 deg. centigrade for 8 hrs., IV) and secondarily burning them in the kiln at 1250-1300 deg. centigrade for 13-15 hrs.

Abstract: AD converter(14) outputs the digitalized signals of internal and external reflecting signals which are analog ones. CPU(15) computes strength of two signals, outputs signal according to their difference. DA converter(17) changes CPU output signal into analog signal and outputs DC level signal. Oscillator for temperature compensation(1) generates original oscillating frequency. Automatic strength controller(2) generates modulated frequency input mixing DC level signal and original oscillating frequency. Light source driving part(3) outputs the signal of laser diode oscillating modulated beam strength using modulated frequency input. Laser diode(4) generates and lets out the laser beam according to the signals input from Light source driving part.
