Abstract: A cushioned tow bar for connecting a drive trolley to a load carriage in a power and free conveyor system includes a particulate shock absorber with a damping chamber which is partially filled with particulate material, such as small ball bearings, which act to dampen the movement of a piston through the damping chamber.  The damping chamber comprises a portion of a sleeve which includes a threaded end cap which mates with threads on an open end of the sleeve.  The threads in the sleeve extend along the longitudinal axis of the sleeve to an extent which allows the end cap to be threadably adjusted, changing the portion of the sleeve forming the damping chamber, and thus adjusting the cushioning effect of the tow bar.

Title: Pressure sensitive switch
Inventor: NEWHAM PAUL F
IPC: G08B21/22
Filed: 1995-07-25
Abstract: A pressure sensitive switch has upper, middle and lower laminar elongated members, the middle member having an opening therethrough defining a cavity between the upper and lower members. A first array of substantially parallel, spaced-apart electrically conductive bands is fixed to a lower surface of the upper member and traverses the cavity. A second away of substantially parallel, spaced-apart electrically conductive bands is fixed to an upper surface of tire lower member and traverses the cavity. Selected lower member bands are discretely connected to an electrical input lead and other lower member bands are discretely connected to an electrical output lead. An array of substantially parallel, spaced-apart dielectric bands narrower than the conductive bands is fixed to one of the lower and upper members and traverses the cavity between the arrays of conductive bands at alternate overlapping points thereof and partially separates the arrays of conductive bands from electrical contact therebetween at said alternate overlapping points. The upper and lower members are resiliently flexible to permit the overlapping points of the arrays of conductive bands to close into and open out of electrical contact therebetween upon exertion and removal, respectively, of a threshold external compressive force to the cavity.

Title: Speech signal encoding system capable of transmitting a speech signal at a low bit rate without carrying out a large volume of calculation
Inventor: TAGUCHI TETSU
IPC: G10L19/113
Filed: 1994-07-06
Abstract: In a speech signal encoding system comprising a maximum similarity series extracting unit (50) for producing a series of excitation pulses appearing at an equidistant time interval and an identical amplitude, the maximum similarity series extracting unit sums up, as a waveform, a series of autocorrelation coefficients to produce a series of summation result coefficients.  The autocorrelation coefficients correspond to polarized pulses which are equal to one another in pulse interval and pulse amplitude.  The polarized pulses form a plurality of pulse sequences which have phases different from one another.  The maximum similarity series extracting unit extracts a polarity of each of the polarized pulses by the use of a dynamic programming method using a degree of an accumulated similarity as an evaluation measure and selects, as the excitation pulse series, one of the pulse sequences which has a maximum waveform similarity between the summation result coefficient series and a series of cross correlation coefficients.

Patent CA-2220733-A1 (CA)
Inventor: CHAMBERLIN JAMES B
IPC: F16C11/06
Filed: 1996-04-18
Abstract: A connector assembly (12) with a connector body (24) molded directly about a captive ball (26) formed on a separate shaft (22), where the shaft (22) and connector (24) are attached to separate bodies which move relative to each other. This assembly retains an essentially zero clearance fit between the ball (26) and the connector (24) so as to prevent rattling between the parts from vibrations. This zero clearance fit is achieved at a much lower cost than comparable quality connectors due to higher diametric tolerances for the ball component (26).      Higher diametric tolerances do not affect the final fit because the connector (24) is molded directly about the ball (26).

Title: Cdma chip synchronization circuit
Inventor: SATO TOSHIFUMI
IPC: H04J13/00
Filed: 1997-11-28
Abstract: A CDMA chip synchronization circuit is provided for a mobile communications system employing a wide band CDMA method, especially direct spread code division multiple access (DS-CDMA) method, and is designed to have a capability to certainly perform detection of multipath receiving timing, particularly synchronous tracking, under a low Eb/No environment where multipaths are received in an overlap manner. Herein, a radio receiver (101) converts radio frequency signals to digital base band signals, whilst a search section (111) detects receiving timing with respect to multipath components contained in the digital base band signals. The detected receiving timing is used as a center position for receiving on a time axis. The radio receiver is connected with multipath receivers (112), each of which contains a number of correlators (102) which produce correlation values between the multipath components and dc-spreading codes which are delayed by different delay times respectively. Herein, the correlators correspond to prescribed intervals of time which deviate from the center position for receiving on the time axis. Correlator outputs are temporarily stored in a memory (103). Then, the multipath receiver selects a correlator output having a best receiving quality from among the correlator outputs by every prescribed interval of time corresponding to a pilot period, so synchronous detection is performed using the selected correlator output. Outputs of the multipath receivers are combined at a maximum ratio, so that receiving data are produced.

Abstract: The support of the transducer (5) comprises an active surface on which piezoelectric elements (6) are arranged juxtaposed in one direction at least of the active surface of the transducer. A mirror (7) having a surface (7') reflecting the ultrasounds is directed towards the active surface of the transducer (5). The reflecting surface (7') is oriented so as to transmit to successive zones of the surface of the elongate part (2) the ultrasounds coming from each of the piezoelectric elements (6), and to send back the ultrasounds reflected by the surface of part (2) towards the piezoelectric elements (6). The transducer (5) is connected to the mirror (7) so that the distance between the transducer and mirror can be adjusted in an axial direction. The invention applies particularly to the control of tubes from the outside or the inside and more particularly to the control of steam generator tubes of nuclear reactors, or sheath-tubes of fuel assemblies.
