Title: Cushioned horseshoe
Inventor: NOFFSINGER ALFRED A
IPC: A01L7/02
Filed: 1993-01-07
Granted: 1997-08-19
Abstract: The   invention   defines   a   shock-absorbing, cushioned horseshoe that substantially absorbs the shock encountered by a horse's hooves and legs when the horse is running or jumping.  The cushioned horseshoe is defined by a mounting plate which is adapted with a plurality of interlocking channel members, wherein one of the channel members includes a plurality of longitudinal locking rib members, whereby a nail may be driven through the horseshoe to engage each locking rib member so as to prevent the nail from being inadvertently loosened after the nail has been driven into the hoof of a horse.  Fixedly attached to the mounting plate  is  a ground-engaging  sole member  that includes openings which are aligned with the holes which are formed in the mounting plate.  The sole member consists of a non-slip, wear resistant, resilient material that is adapted for direct engagement with the ground surface.  The resilient material is molded to the lower surface of the mounting plate and is received in each of the channel members, whereby the resilient material becomes fixedly secured to the lower surface of the mounting plate during the molding process to prevent separation therefrom.

Filed: 1993-04-14
Granted: 1999-01-19
Abstract: An arc detector for detecting electrical arcs across a break in a line carrying a current in an electrical system. Normally, the line carries current, but when the line is broken, current doesn't flow until an arc occurs across the break.  The arc detector detects the break using a current sensor for measuring the current, a filter for filtering out unwanted frequencies, an amplifier for amplifying the remaining frequencies into a substantially square wave, a counter for counting square wave transitions, and a latch to hold a detection signal at an output node when the counter counts a preset number of square wave transitions without being reset by a reset switch or a periodic oscillator.

Filed: 1993-04-27
Granted: 1998-11-24
Abstract: An  image coding/decoding apparatus  intended  for efficient  processing  by sharing  members  in  coding, local decoding,  and decoding  processing.   Processes such as DCT and IDCT, zigzag scan conversion and inversion,  or quantization and inverse  quantization  performed in coding, local decoding, and decoding processing  are similar to each other.          DCT/IDCT, zigzag scan conversion/inversion, and quantization/inverse quantization  are provided where either of the two functions can  be selected for execution in synchronization with the  processing timing for each block.          Since the time required  for  one process for data for each block is very  short, overall processing is not affected even if  the  members  are used in a time division manner.   By sharing  processing, the hardware scale can be  made small and by using a data bus in a time division  manner, an external data bus can also be eliminated.

Abstract: A method for metallurgical enhancement of a failed bolt hole, or stud attachment, providing for replacement of service induced failed material from the female threaded area of the bolt hole. A method in accordance with the present invention is particularly suited for power plant equipment, such as a steam turbine. Failed material from the female threaded area is removed and filler metal is arc welded to the exposed base metal of the hole using a mechanized gas tungsten arc weld device employing a continuous spiral weld bead.      Proper selection of the filler metal, considering the base metal to which it is applied and, moreover, the type of failure which the base metal o! the hole has been experiencing, provides for improved structural integrity of the mechanical joint and increased service life of the associated steam turbine apparatus. Weld tempering of the filler metal reduces undesirable weakening of the weld metal in the heat affected zone, thus providing further metallurgical enhancement of the failed bolt hole.

Abstract: Our audio processing system for use in teleconferencing systems includes a microphone (1-25), receiver (1-26), and substantially the same comb filter (1-42) and frequency scaler (1-60) at each station for reducing acoustic echo and increasing the margin of acoustic stability. The comb filters and frequency scalers cooperate with one another in that the frequency scalers each induces a shift in frequency which corresponds to the peak-to-trough spacing of the transfer function of the comb filters. Our audio processing system may also include auxiliary echo suppressors (410, 510) for reducing acoustic echo and increasing the margin of acoustic stability in systems having high and low transmission delays. Other devices may be employed for reducing noise and smoothing out the operation of individual components in the system. Since the comb filters employed at each station are not complementary, but are substantially the same, our audio processing system can mitigate the effects of acoustic instability and echo in point-to-point and multipoint audio processing systems. Furthermore, since each station utilizes substantially the same equipment, the need for equipment negotiation between stations and equipment changes prior to a conferencing session is obviated.
