Patent CA-1317372-C (CA)
Inventor: EDEL STEPHEN F
IPC: G11B21/10
Filed: 1988-09-16
Granted: 1993-05-04
Abstract: ABSTRACT     A disk file digital servo control system incorporates means for measuring the time between samples of read/write head position error signals (PES), and uses a value of that measured time as part of the computation of the digital control signal. The digital servo control system has a microprocessor which runs a control signal algorithm, a portion of which is a state estimator for estimating the position, velocity and acceleration of the head. The state estimator requires the use of estimator constants determined from physical parameters of the disk file, including the PES sampling time. By using the actual measured PES sampling time, rather than a constant value of nominal PES sampling time, the estimator constants can be modified to improve the accuracy of the computed control signal. This results in improved performance of the control system to move the head to the target track whenever there are variations in the nominal PES sampling time caused by variations in the disk file drive motor speed.

Abstract: ABSTRACT DISPOSABLE DIAPER HAVING SHIRRED EARS         The back ears of a contoured disposable diaper are shirred to become stretchable and elastically retractable.  Because of this, the diaper can be pulled snugly around the buttocks and the waist merely by applying ordinary fingertip pressure to the fastening tabs.  The shirring can be provided by incorporating into the back ears of a flat diaper-forming blank a piece of heat-elasticizable material and then heating each diaper that is cut from the blank to shrink the piece.  A preferred heat-elasticizable material comprises a substantially flat inelastic web to which is heat bonded a plurality of parallel elastomeric strands extended to at least about three times their relaxed length.

IPC: B29D5/00
Filed: 1988-12-08
Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE           A method  for continuously producing an elongated strip-like fastener member is disclosed which facilitates highly efficient formation of the fastener member with a great multiplicity of resiliently flexible hook-like projections.  The method comprises the formation of an extrusion of plastic material which is shaped between a pair of coacting first and second rollers. Notably, one of the rollers is formed of a series of plates and defines a plurality of hook-forming cavities about its periphery within which the hook projections of the fastener member are formed.  The forming roller is suitably cooled so as to effect substantial reduction in the temperature of the molten plastic extrusion form which the fastener member is formed.  In this manner, the fastener member may be removed or stripped from the forming roller without opening of the hook-forming cavities, thus promoting highly efficient formation of the fastener member without resort to unduly complex equipment processes.  The fastener is uniquely configured and includes upstanding hook-like engaging elements having stem portions of at least partially arcuate configuration to produce a combination of properties previously unknown in such fasteners.

Title: Pressure sensor
Inventor: SORRELLS DAVID F
IPC: G01L11/04
Filed: 1989-01-04
Granted: 1992-04-28
Abstract: PRESSURE SENSOR           ABSTRACT OF THE DISCLOSURE       A  pressure sensor for accurate readings of low pressures utilizes an ultrasonic transmitter which sends a signal to a movable diaphragm via a waveguide.        Pressure changes across the diaphragm causes changes in the signal path length from transmitter to receiver which are translated into pressure readings via electronic circuitry employing phase comparator circuitry.  The received signal is split into two signals one of which is shifted in phase.  A temperature responsive controller selects which received signal is used in a comparison with the transmitted signal thus greatly extending the temperature range over which the sensor operates.  The use of an ultrasonic waveguide with a length of at least twice the frequency of the transmitted signal coupled to the transmitter eliminates echoes and reflections and provides for enhanced accuracy in reading even very low pressures .

Granted: 1993-03-30
Abstract: Abstract The invention relates to drilling equipment, particular-ly for drilling shot holes, comprising a carriage for advancing and withdrawing the drill pipe formed from a plurality of drill stems, an advance system, a pressure-operated drive system for the drill pipe, a flushing head that is arranged on the carriage and which can be moved either with or apart from the drill pipe, and an hydraulically operated in-hole hammer arranged on the front end of the drill pipe.  To provide drilling equipment of the afore-named kind which allows the rods to be changed simply and quickly when using an hydraulically operated in-hole hammer arranged at the front end of the drill pipe, it is proposed in accordance with the invention that the pressure-operated drive system (15) of the drill pipe transmit a back and forth swivelling movement to the drill pipe.  The pivoting angle of the drill pipe is 180 - 360°.          An oscillating motor with a gear system (16) is used for the drive system (15).  It is thus possible to accommodate the lines required for acting on the in-hole hammer in the annular space between the drill pipe and the wall of the drilled hole or in indentations of the drill pipe itself so that they need not be disconnected when the rods are changed.

The plates are separated from each other by a preferably elongated gap (18) and the upper surfaces of said plates are largely covered by upper electrode surfaces (24-26). The thermistor plates (14-17) are arranged within a limited area of the carrier (10) so that the maximum aggregate area of the thermistor plates (14-17) is constant, whereas the size of each individual thermistor surface is variable by displacement of the position of the gap(s) (18) within the said limited area of the carrier (10), for adjustment of the total resistance of the thermistor to different values.            The invention also relates to a procedure for manufacturing a thermistor.

Abstract: An automatic correction system for the servo-circuit of a device with optical scanning of a rotating information support, with a known servo-circuit, for detecting anomalies in the scanning system (1) to whose outputs is connected a gate circuit, providing as necessary a mute control signal at the decoder (2) connected to the scanning system (1) and thus ensuring the mute control of its outputs. According to the invention, anomalies in scanning caused by external faults and/or disc faults, such as scratches, can largely be reduced, in terms of the disturbance caused by this phenomenon, by the fact that a triggering criterion for correction signals can be produced, in the event of anomalies, by sequential address comparison. This is achieved by the fact that a comparator (6) compares any newly read data with the preceding information, which is temporarily stored in a latch circuit (7) and by the fact that a preliminary indication is made available, in the form of a measurement window $g(D) D in order to determine whether the comparison lies outside the measurement window and in order then to emit a correction signal from the comparator (6) to the servo system (3) and by the fact that the scanning system (1) refers back to the last valid scanning point.
