Title: Synchronizing signal detection apparatus
Inventor: NAKATA HIROSHI
IPC: H04L7/04
Filed: 1995-05-12
Abstract: A synchronizing signal detection apparatus of the present  invention  comprises  a  demodulator  for  digitally demodulating input signals, a partial matching error counter for comparing every bit of the demodulated input signal bit pattern demodulated by said demodulator with a part of the known synchronizing signal bit pattern.  The apparatus further comprises a remaining bit matching counter for comparing the input  signal  bit  pattern  with  remaining bits  of  the synchronizing signal bit pattern used in the partial matching error counter, or with all synchronizing signal bit pattern, for every bit, when an error bit number, which is compared in the partial matching error counter, is equal or less than a first threshold value. When the error bit number compared in the remaining bits matching error counter is equal or less than a second threshold value, synchronizing signal is assumed to be detected.  In the apparatus of the present invention, bit pattern comparison numbers are decreased.

Abstract: L'invention concerne un kit comprenant un ensemble de pièces différentes permettant d'ériger une structure d'abri qui peut être rapidement montée et démontée à partir de tiges rectilignes flexibles, de pièces de jonction pour assembler entre elles les tiges, et de pinces pour maintenir en place une toile ou une couverture sur la structure. Le kit est facile d'usage dû à son nombre restreint de pièces différentes. Il permet d'assembler rapidement des structures de grandeurs et de formes variées. Il requiert peu de place pour le rangement dû au fait que les tiges sont toutes rectilignes et semblables. Les pièces de jonction sont cylindriques, en forme de croix et/ou en forme de T. Grâce à ces pièces et aux tiges, une multitude de formes et de grandeurs de structure peuvent être aisément obtenues. Ces structures peuvent être recouvertes d'une toile ou d'une couverture qui peut être attachée aux tiges par les pinces.

Inventor: LADIN ELI M
IPC: F16D25/08
Filed: 1996-02-23
Abstract: A control for a heavy vehicle clutch wherein control members are moved rearwardly away from an engine to disengage a clutch from an engine and engage a clutch brake disc. A pair of co-acting multiple actuators are independently mounted at fixed locations on sides of a bell housing which encloses the clutch. The actuators are spaced apart from a longitudinal axis of the clutch and produce a resultant force which is substantially collinear with the longitudinal axis of the clutch. The actuators have outward extendable push rods which move rearwardly when a foot pedal is depressed to disengage a clutch and move forwardly when the pedal is disengaged to engage the clutch.      The push rods engage a movable member which is centered on the axis of the clutch having an outer side portion for restraining the clutch brake disc from rotating when the clutch is disengaged.

Title: Wand inductor for remediation of contaminated soil
Inventor: FULTON A CARL
IPC: C02F11/02
Filed: 1996-04-04
Abstract: The invention is a batch process for biotreatment of contaminated soil according to which the material is placed with microbes and  water in a vessel such as a roll-off box with aerators.  A slurry recirculating system is used every few days at a point of microbial domination to pump material from the water column into the solid phase at high pressure through a wand inductor, whose outlet is directed around the vessel to shear and agitate essentially the entire volume of material.  The configuration of the vessel, agitation with the wand inductor and control of other conditions allows cost-effective microbial degradation of hydrocarbons to regulatory standards in soils having large amounts of clay, rocks, and debris.

Title: Field repairable shielded conduit termination system
Inventor: GOETT EDWARD P
IPC: H01R9/05
Filed: 1996-05-10
Abstract: A cable termination system for heavy duty cables having a threaded metallic or plastic shield includes only two members; a termination body and a termination nut, the former having internal threads mating with an internal thread shield of the cable and the latter having rounded internal threads mating with rounded external threads of the termination to clamp at least the outer braids of the cable between the external threads of the termination and the internal threads of the termination nut. The termination body is screwed onto the shield and provides an annular pocket to receive the end of the shield to protect the wires of the cable from burrs and sharp edges at the end of the shield. The internal threads of the termination have a different pitch from those of its external threads whereby the threads bind the termination nut and prevent it from becoming unscrewed from the cable. The termination nut is locked in place by snap rings and its end seats against an O-ring to isolate it from the environment while the other end of the nut engages a projection on the termination body to seat the outer covering of the cable between the two elements of the system.

Title: Voice/Unvoiced Classification of Speech for Use in Speech Decoding During Frame Erasures
Inventor: KROON PETER
IPC: G10L25/93
Filed: 1996-05-27
Abstract: A speech decoder includes a first portion comprising an adaptive codebook and a second portion comprising a fixed codebook. The decoder generates a speech excitation signal selectively based on output signals from said first and second portions when said decoder fails to receive reliably at least a portion of a current frame of compressed speech information. The decoder does this by classifying the speech signal to be generated as periodic or non-periodic and then generating an excitation signal based on this classification. If the speech signal is classified as periodic, the excitation signal is generated based on the output signal from the first portion and not on the output signal from the second portion. If the speech signal is classified as non-periodic, the excitation signal is generated based on the output signal from said second portion and not on the output signal from said first portion.
