Title: Torque sensor for expanding pulley transmission has two plenum chambers
Inventor: FRIEDMANN OSWALD
IPC: B62M9/04
Filed: 1995-12-06
Abstract: A hydromechanical torque sensor 14 for an expanding pulley has cam discs 18, 19 with conforming cam faces between which are located spreading elements 20 to tend to move the cam faces apart under high torque to act in use on one half of the expanding pulley via first and second plenum chambers 22, 23 connected to a source of hydraulic fluid under pressure. Supply to the chambers 22, 23 is via a throttle. The plenum chambers 22, 23 of the torque sensor 14 can be connected to or sealed from each other preferably as a consequence of change in the effective diameter of the pulley to change the ratio of a transmission including the pulley. The connection between the chambers may be allowed by one-way action of a lip seal 67 or by a valve. <IMAGE>

Title: Rolling road vehicle vibration testing
Inventor: MARSHALL DAVID BRYAN
IPC: G01M17/007
Filed: 1996-02-01
Abstract: Apparatus for measuring vibrations in a wheeled vehicle 20 comprising at least one roller 10,12 having a contact surface 18 thereon, formed from four shells 16 for contacting a wheel 22 of the vehicle. The computer (14, Fig 2) which analyses signals from the sensors 24, 26 controls the drive means for driving the roller to vary the speed of the roller gradually over said test period about a nominal speed. The vibrations induced by the repeating nature of the contact surface therefore change in frequency over the test period and produce less interference with the vibrations of interest which are produce by the contact surface irregularities. This enables narrow band data processing techniques such as road noise path analysis to be carried out on a rolling road.
Patent GB-2300777-A (GB)
Title: Printhead having data channels with revisable addresses for interleaving scan lines and pixel replication
Inventor: HAAS DANIEL DILLON
IPC: H04N1/23
Filed: 1996-05-08
Abstract: A multiple-source array for use in thermal printing uses source interleaving to avoid overlapping of the dye-transfer tracks upon the donor material in a single pass. This prevents the formation of artifacts in the image because of thermal interaction among either the sources or printing spots. This also permits the thermal array to be oriented predominantly perpendicular to the first-scan direction so that any arcuate shape of the array causes minimal spacing variations of the scan lines and minimizes spacing variations in focus or document source separation for resistive-head thermal printing. Interleaving also allows multiple printheads to be used even when they have different printing characteristics. The array includes independently addressable printing element data channels 64 and a data distributor 62 allowing interleaving to be accomplished in the printhead. The printhead also includes pixel replication circuitry that allows pixel replication in both the fast and slow scan directions.

Title: A transparency sensor
Inventor: MULLENS RICHARD ANDREW
IPC: G01S17/04
Filed: 1996-12-18
Abstract: A transparency sensor 10 which uses Brewster's Law to detect the presence of sheets of transparency material 20. The sensor comprises a light emitting diode (LED) 12 and two photodiodes 14, 16 arranged to receive light reflected from the material. The LED supplies incident light at angle * small Greek theta * which is around the Brewster angle for most transparency material to be detected. A polarising filter 18 is associated with one of the photodetectors and is orientated to cut out substantially reflected polarised light entering that photodiode. Output signals from the photodetectors are processed in a comparator 40 which provides an output signal 42 indicating the presence or otherwise of transparency material. Further, the sensor may distinguish between paper and a transparency, and in addition both detectors may have associated polarising elements.

Title: Constant rate discharge pump and method
Inventor: SAKAYORI TOSHIMASA
IPC: G05D7/06
Filed: 1997-03-10
Abstract: A pump unit 15 is provided which sucks a material M having a high viscosity contained in a container 13 and pumps it at a constant rate to a nozzle 16 under pressure. An axial member 17 for operating the pump is driven axially by the pressure of air or hydraulic fluid supplied to a cylinder 18. The material which is sucked into the pump unit is discharged from the nozzle by the increase in pressure which occurs when the axial member descends. A sensor 30 is provided in the vicinity of the axial member 17 to determine the speed of the axial member. A reference speed when constant rate delivery is performed is preset in a controller 33. Correction of the pressure supplied to the cylinder is conducted by comparing the actual moving speed of the axial member with the reference speed.

Title: Channel searching and fine tuning in a digital TV receiver
Inventor: MAEDA SHUNJI
IPC: H04N5/44
Filed: 1997-10-24
Abstract: In digital satellite TV broadcasting the frequencies are not always fixed and so a channel search may be necessary. Fine tuning in such digital systems has used demodulated information but this is time consuming. Here discrimination before the demodulator is used to gather fine tuning information which is then stored for future use. During the search the demodulator may be switched off and the gain may be fixed. Various discrimination procedures are described.
