Title: A method and circuit for detecting auto tracking find error in VCR
Inventor: OH YONG KYO
IPC: G11C8/08
Filed: 1992-11-06
Abstract: A method and a circuit for detecting an auto tracking find error in a VCR, wherein a phase control range for a capstan motor is widened as compared with the prior art so that, when a phase of the capstan motor is widely detuned, the following speed for stabilization of the phase of the capstan motor can be made fast. In an interval of - pi -  pi  of the phase of the capstan motor, first latch data is selected as a phase error signal for control of the phase of the capstan motor. In intervals of -2 pi  - - pi  and  pi  - 2 pi  of the phase of the capstan motor, second latch data is multiplied by two and is then of the same polarity as that of the first latch data. The second latch data multiplied by two is added to the first latch data. In result, the added value is selected as the phase error signal. Also, a portion of the data above double the upper limit value is cut in the interval of -2 pi  - - pi  and a portion of the data below double the lower limit value is cut in the interval of  pi  - 2 pi . <IMAGE>

Title: Backwashing filter beds
Inventor: MOORE RICHARD PIERPONT
IPC: B01D24/00
Filed: 1993-10-13
Abstract: Filtered water from a bank of separate downward flow filter beds is partly discharged at 16 and partly stored in a common reservoir 12 and used to backwash the beds in turn. A duct 2 feeds unfiltered water to each bed 23 via a space on one side of an overflow 6, maintaining normal water level 19 above the bed. When backwashing, the level is reduced to that of overflow 6, valve 16 is closed and valve 7 opened to discharge used backwash water to duct 8. Section 10 of standpipe 9 in reservoir 12 is then raised to backwash the bed under gravity. In other constructions the filtered water reservoir is located more on a level with the filter beds and is forced back through the beds by compressed air delivered into the reservoir. Compressed air is also fed through valve 20 to agitate the bed before backwashing. In Fig. 5 the water passes through a multiplate setting stage upstream of the filter beds, and used backwash water is directed to the same setting stage. <IMAGE>

Title: A Digital cellular mobile radio receiver
Inventor: DEVILE JONATHAN MARK
IPC: H04L25/03
Filed: 1994-03-10
Abstract: The digital cellular mobile radio receiver comprises a channel estimator 4 which receives on an input line 2, digital samples of I and Q baseband data in the form of a transmission burst. The transmission burst is also applied to an input of an equalising filter 8. The channel estimator generates an output signal which is an estimate of the impulse response h(n). This is applied to a filter response calculator 6 which generates an impulse response signal c(n) which is applied to the equalising filter 8. The equalising filter 8 convolves the signals c(n) with the transmission burst and cancels any inter symbol interference. The output of the filter 8 is applied to the input of a demodulator 10 from which output signals are generated on an output line 12. The receiver provides simple equalisation of a received digital sequence and high speed detection of the received transmission bursts. <IMAGE>

Title: Reactor for generating hydrogen from metal hydride and water
Inventor: ADLHART OTTO J
IPC: H01M8/06
Filed: 1995-06-28
Abstract: The reaction of metal hydride with water is utilised for the generation of hydrogen in a novel generator configuration which overcomes the problem associated with the expansion of the hydride upon its conversion to hydroxide or oxide when reacting with water. The hydride cartridge 10 is comprised of a structure of corrugated perforated sheet metal 13 and layers 12 of water wicking material having hydride granules 17 dispersed therein. The hydride cartridge is housed in a reactor to which liquid water is admitted in a controlled mode. As the water enters the reactor via tube 14 and reaches the cartridge via perforations 15 hydrogen is instantaneously generated by the hydride water reaction. The hydrogen generation continues as long as unreacted hydride remains and water is being admitted. As the reaction proceeds the volumetric expansion associated with hydride expansion is accommodated by compression of the corrugations of the sheet metal cartridge structure. The combination of the corrugated cartridge structure and the wicking material dispersed throughout the cartridge facilitate the complete utilisation of the hydride and water in a demand responsive mode. This is important in applications where intermediate hydrogen storage is impractical, as is the case in the use of these generators - e.g., for electric power generation in fuel cells in general and for Underwater Vehicles specifically because space restraints. <IMAGE>

Title: Rubber testing
Inventor: WATSON WILLIAM FERGUSON
IPC: G01N33/44
Filed: 1996-09-06
Abstract: A test sample of raw or compounded rubber is squeezed from a loading chamber 7 through selectively-aligned passages 8 and 12 to fill an annular space 1 between a coaxial stator 5 and rotor 4. Measurements of viscous torque are provided by a sensor 15, and a load cell 14 provides measurements of the force exerted axially by the sample. The torque and axial-force measurements are plotted against time (16 Fig 4, 17 Fig 5) as representative respectively of the viscosity V and elasticity of recovery E of the sample, and are compared for correspondence (within limits 19, 20) with earlier-plotted characteristics of an acceptable rubber for processing. Temperature of the sample is regulated by a heater 18 and rotation of the rotor 4 is at a speed and for a duration corresponding to that of the next processing stage.
