Title: Measuring the calorific value of a gas using ultrasound
Inventor: HAMMOND PAUL STEPHEN
IPC: G01N29/32
Filed: 1997-04-10
Abstract: Energy meter 2 comprises a combustible fuel gas inlet 48, fuel gas outlet 50 and a central tube 12. The speed of ultrasound signals travelling through the tube 12 between transducers 52, 54 can be measured and used to calculate the volume of gas which has passed through the meter. Another ultrasound transducer 66 in chamber 32 acts as an emitter and receiver of ultrasound signals reflected by reflectors 68, 70. The measured attenuation and/or speed of signals from transducers 52, 54 and/or 66 is used to derive the calorific value and/or Wobbe index of the gas. Control 56 uses the volume of gas and the calorific value and/or Wobbe index to derive the amount of energy provided by the supply of the gas. Values for gas temperature, pressure, thermal conductivity and/or specific heat capacity from sensors 60, 62 and 72 may also be used by control 56.

Patent GB-975252-A (GB)
IPC: A43D111/00
Abstract: 975,252. Fluid - pressure brake control. AUTOMOTIVE PRODUCTS CO. Ltd. March 13, 1961 [May 24, 1960], No. 18324/60. Heading F2F. [Also in Division G3] In a liquid pressure braking system a deceleration controlled servo 16 closes a shut-off valve 29 between the master cylinder 13 and the wheel cylinders 12 and also moves a pressure balanced plunger 32 to increase the volume of the system connected to the wheel cylinders when the valve 29 is shut. Under normal braking liquid pressure passes from the master cylinder 13 past the stop valve 29, held off a seating 27 by a pin 33, forming the end of a double plunger assembly 32, 37, biased by a spring 45 of a vacuum servo unit 16, through passage 41 to the wheel cylinders 12. The liquid pressure is also transmitted through a passage 40 to a chamber surrounding the plunger 34 and impinges on the annular area of a head portion 35 which is equal in area to the plunger 32, thus balancing the plungers. On excessive deceleration the deceleration responsive means 18 closes the chamber 47 to vacuum from engine inlet manifold 21 and opens the chamber to atmosphere; the chamber 44 being open to vacuum, the plungers 37 and 32 are moved to the left by diaphragm 43 and the valve 29 is seated by a spring 31 to shut off the liquid pressure to the wheel cylinders. As the plunger 32 moves the volume of the chamber at its right-hand end increases and decreases the wheel cylinder pressure to release the brakes. The deceleration responsive means 18 comprises a double-acting valve 17 which connects a passage 68, connected to the chamber 47, to vacuum through passage 70 under normal conditions and to atmosphere through chamber 69 when a flywheel 52 runs on in relation to the casing 51 and causes camming balls to run up in radial grooves in cam plates 53, 55. The casing 51 is belt driven from a transmission shaft 20 and drives the flywheel 52 through the camming balls and a friction washer 61, the cam-plate 55 being resiliently supported and driven by a dished spring 56. In a modified deceleration responsive means a double-beat valve 17 closes one seating before opening the other, and the flywheel is driven frictionally through a sleeve driven from the casing.

Title: Fault restart routine for an icemaker
Inventor: ALLISON MATTHEW W
IPC: G05B9/03
Filed: 1998-06-10
Abstract: A fault restart routine for an icemaker with a microprocessor-based system controller provides at least a limited number of attempts at automatically restarting the icemaker after a shutdown has occurred because of a detected fault condition. If the fault is a general fault condition 52, a fault counter is incremented 70 and the routine waits a first predetermined time 80 before attempting a restart 82. If the fault is a water inlet fault 52, the routine waits for a second predetermined time 58 before attempting a restart. If after restarting, the icemaker completes one complete cycle of operation, then the fault restart routine is exited 86 and the fault code is cleared. If the icemaker does not complete the cycle, the counter is incremented once again 70, if a general fault is detected. Further automatic restarts are attempted up to a predetermined number, and then the system controller generates a fault signal 74 to an LED display, and no further restart attempts are made 76.

Title: High-speed cell search system for CDMA
Inventor: TSUGUO MARU
IPC: H04W56/00
Filed: 1998-06-16
Abstract: In a high-speed search system for CDMA, plural (M) symbols, which are subjected to spread frequency coding with a spreading code called as a short code, are prepared when synchronization of the spreading code is established before carrier synchronization is established in a mobile station used in a CDMA cellular system. Data which are obtained by forming an orthogonal code with the polarities of the M symbols are set as a down signal. When the orthogonal code concerned is detected, coherent integration is performed by a correlator 21 having combinations of the polarities which can be possibly taken by the code over the plural symbols (of M) constituting the code. Long-code identification 25 follows.

Title: Method of storing compressed sensitometry data on media to be read by the printer
Inventor: SCHILDKRAUT JAY STUART
IPC: B41J35/36
Filed: 1996-02-15
Abstract: Sensitometric information is stored with a consumable print medium having a predetermined sensitometry by compressing the sensitometric information as a set of spline coefficients for use with a printer adapted to decode the set of spline coefficients to construct a sensitometric curve. A set of spline coefficients is generated, spline coefficients are encoded, and the encoded spline coefficients are stored on the media or on a cassette containing the media which is accessible to a printer adapted to make use of the media sensitometry data for purposes of device calibration. The coefficient-generating step comprises fitting a spline curve to the sensitometry data. The spline curve may be monotonic cubic. The encoding step may include encoding a difference signal representing a difference between input values for a set of sequential spline knots. The encoding step may also include encoding a difference signal representing a difference between the output values of the sensitometry curve and output values of a reference sensitometry curve for each of a set of sequential spline knots. The difference signal may be encoded by quantizing the difference signal into a set of discrete bins.

Title: Adjustment of printhead gap by sensing the contact between the printhead and a recording medium or the contact between a carriage probe and the medium
Inventor: DIETEL KLAUS
IPC: B41J25/308
Filed: 1999-01-12
Abstract: The printhead 1 is mounted on a carriage 5 by a spring clip 13 with interposed resilient layer 12. To calculate the printhead gap, the print element end la of the printhead is moved briefly by the carriage and an associated drive into contact with a recording medium 7 whereby a displacement of the print head relative to the carriage occurs. This displacement is sensed using an LED and phototransistor assembly 14-16 on the carriage in conjunction with a reflecting surface 17 on the print head. This sets a datum by which correct positioning of the printhead relative to the medium may be achieved taking account paper thickness and the number of plies. Alternatively, the LED and phototransistor assembly may be replaced by a Hall Effect sensor and magnet. A signal processing and filtering circuit (Fig.4) is used to compensate for vibration and other disturbances. In a further embodiment, a part of the carriage has a probe (30,Fig.5) which is displaceable to produce relative movement between the two surfaces carrying the parts of the sensor.

Title: Air-gap winding impregnated with magnetic material in a binder
Inventor: EVISON PETER ROBERT
IPC: H02K3/04
Filed: 1999-03-26
Abstract: An air-gap winding, in which the magnetic flux is caused to pass through a magnetic material (40) rather than through the strands of the winding which are typically made from non-magnetic material such as copper, comprises mixture of discrete particles of the magnetic material (40) and a binder (41) impregnated into the winding under pressure, particularly in gaps (43) between individual wires (50) of the winding and in gaps between individual strands (42) in the wires (50). To avoid unsuitable deformation of the winding, the winding is non-circular in section, so that the mixture (40,41) is forced inwardly and outwardly through cavities formed between a stator (27) and the winding, and between the winding and a cylindrical inner member (32). Litz wire is used as for the individual wires 50.
