Patent CA-2040408-A1 (CA)
Inventor: VOSS RICHARD
IPC: E21D23/16
Filed: 1990-07-27
Abstract: A pressure limiting valve (1) with flow rates of 2000 litres per minute and over has a valve piston (10) in the form of a tubular sleeve (20).  With the attached control piston (60), this valve piston (10) forms a structural unit in which the control piston (60), the diameter of which is correspon-dingly smaller, is loaded by means of a spring plate (26) and a valve spring (11) which is adjustable and predetermines the force at which the valve (1) opens.  The specially stepped construction of the valve piston (10) and its large diameter are possible because use is made of special kinds of sealing rings (19, 51 and 75) bearing on the outside on the large-diameter valve piston (10) and on the control piston (60) without hampering their movement significantly through fric-tion.  A good seal is nonetheless ensured because the sealing rings used (19, 51, 75) are very hard but create little fric-tion and lie closely against the valve piston (10) and the control piston (60) owing especially to the construction of the annular groove (50, 55 and 76) with a bevel (54, 58, 77).

Patent CA-2046709-A1 (CA)
Inventor: BEARDSLEY BRENT C
IPC: G06F3/06
Filed: 1991-07-10
Abstract: A cached DASD controller is illustrated which is attached to a high  speed  serial  channel,  such  as  an  optical  fiber channel.   The  data  rate  of  the  serial  channel  is  much greater than the data  rate  of a DASD connected to  the controller.   The  serial  channel  has  a  relatively  long propagation time such that synchronous operations between the host processor 10 and the DASD cannot be efficiently performed.   Operation of a data transfer, whether read or write  between  the  host  processor  10  and  the  DASD  is monitored.   Whenever a copy of the track contents and in cache and the DASD reaches either an index mark with or a break point from a roll mode operation or certain write operations  occur  resulting  in  predetermined  data  being stored in cache,  then a GOCACHE flag is set in a control portion of the controller.  The device operations are then momentarily idled while cache to host processor operations are enabled.

Title: Apparatus for monitoring the motion components of the spine
Inventor: MARRAS WILLIAM S
IPC: A61B5/11
Filed: 1990-04-12
Abstract: Abstract An apparatus is disclosed for monitoring the functional motion characteristics of the spine in each of three planes.  The apparatus is designed to be mounted on the back of a patient, and it includes an exoskeleton of T-shaped elements which resemble the spinous process and the transverse process of the spine.  The elements each include a central bore for receiving a cable, and three separate openings for receiving a wire therethrough.  The cable is attached to a potentiometer which measures twisting movement of the spine, and each of the three wires is attached to a separate potentiometer so as to measure flexing in the and sagittal and transverse planes.  The signals from the potentiometers are processed so as to provide, for each of the three planes, a measurement of the angular position of the spine as a function of time, the angular velocity as a function of time, and the angular acceleration as a function of time.

Abstract: ABSTRACT OF THE DISCLOSURE             A seismic logging system for VSP or cross well data capture set forth. It is comprised of M duplicate recording stations connected serially below a main structure suspended on a logging cable. Each of the recording stations preferably includes orthogonally arranged displacement transducers, and they are in turn connected with suitable amplifiers, filters and converters  to form digital words,  and  the  digital  words  are recorded in organized fashion in a memory. A telemetry unit is connected to that memory for transfer of data. This data transfer takes place over a short distance into the main unit, and the main unit includes a much larger memory for storing and holding data from M recording stations deployed along and there below in the well borehole, and further including telemetry means for transfer of data along the logging cable. The main memory and the main telemetry means operate at different rates and different capacities; each recording station has its own memory and telemetry means to individually form data words which are first stored locally and then transferred to the main memory where upon telemetry along the logging cable subsequently occurs.

Title: Speech detection circuit
Inventor: KOMATSU NORIYOSHI
IPC: G10L11/02
Filed: 1991-10-10
Abstract: A speech detection circuit includes an amplifier for amplifying an input audio signal and having a variable gain, a rectifying circuit for rectifying an output signal of the amplifier, a comparator for comparing an output signal level of the rectifying circuit with a reference level, and a control circuit for outputting a control signal based on an output signal of the comparator.  The control circuit outputs a control signal which indicates a power save mode after a predetermined time elapses from a time when the output signal level of the rectifying circuit becomes less than or equal to the reference level, and outputs a control signal which indicates a normal mode immediately when the output signal level of the rectifying circuit becomes greater than the reference level.  The amplifier receives the control signal output from the control circuit and reduces its gain when the control signal indicates the power save mode.

Abstract: A method and apparatus is provided for transmitting spread spectrum signals. The transmitter receives data bits (200) at a particular rate. Subsequently, the transmitter encodes (202) the received data bits (200) at a predetermined encoding rate into data symbols (204). Subsequently, the transmitter derives (210) predetermined length orthogonal codes (212) from the data symbols (208). The transmitter accommodates variable received data bit rates by setting the predetermined encoding rate and the predetermined orthogonal code length in response to the received data bit rate. Subsequently, the transmitter spreads (216) the derived orthogonal codes (212) with a user PN spreading code (214).      An alternative method and apparatus is provided for transmitting spread spectrum signals. The transmitter receives data bits (230) at a particular rate. Subsequently, the transmitter encodes (232) the received data bits (230) at a predetermined encoding rate into data symbols (234). Subsequently, the transmitter determines (248) a particular channel to transmit the data symbols (244) by spreading (248) the data symbols (244) with a predetermined length orthogonal code (246). The transmitter accommodates variable received data bit rates by setting the predetermined encoding rate and the predetermined orthogonal code length in response to the received data bit rate.
