Patent GB-2221769-A (GB)
Title: Improvements in electric motor control
Inventor: HUTTON GREGORY THOMAS
IPC: H02H7/085
Filed: 1988-08-09
Abstract: An electric windowlift system is disclosed in which a window 22 is moveable between an open position and a closed position by an electric motor 11 and associated actuator mechanism 19. A control system 10 for the electric motor 11 monitors the back electromotive force pulses generated by the electric motor 11 and uses this information to produce signals indicative of window position and speed. If the control system 10 senses that the window speed has dropped to zero while the window 22 is being closed it acts so as to switch off the electric motor 11. Serious injury to vehicle passengers by the entrapment of one of their limbs is thereby prevented. <IMAGE>
Patent GB-2211952-A (GB)
Title: Radiometers
Inventor: WILLIAMS BERNARD
IPC: G01K11/00
Filed: 1988-10-31
Abstract: A radiometer has a reference noise source provided by a local oscillator 22 which is modulated at the Intermediate Frequency by a sine-wave source 23 of very stable amplitude. A dual-channel superheterodyne receiver 10 receives the reference VA at one input of its mixer 11 and at the other input receives either a standard Y or an unknown X noise signal, the two inputs being combined by the action of an RF hybrid within the mixer. The second channel contains a phase- reversing switch 17. The sine-wave source 23 must be adjusted so that a phase-sensitive detector 21 shows a zero reading, whereupon the reading on a power meter 24 is noted. A computer 25 monitors the output of the phase-sensitive detector 21, adjusts the sine-wave source 23, takes power readings from the power meter 24 and calculates a value for the unknown noise source Y. Since all control and data signals are purely electrical the system is very fast, and no external attenuator is necessary. <IMAGE>

Patent GB-2233117-A (GB)
Title: X-ray mask
Inventor: KANG HO-YOUNG
IPC: G03F1/22
Filed: 1989-06-29
Abstract: An X-ray mask for producing micro scale images on semiconductor substrates is constituted such that a grounded charge conducting film 30, e.g. Al, is deposited between X-ray transmissive base plate 20 e.g. SiC or SiNx and an X-ray absorbing image 40, e.g. metal to absorb the charges accumulated around the X-ray absorbing image, thereby making it possible to correctly inspect the line width and defects of the pattern of the mask. The charges accumulated around the X-ray absorbing image in the prior art make the scanning electron beams deflected so that correct measuring of the pattern of the mask becomes impossible. Therefore, the charge conducting film which is grounded absorbs the produced charges before they accumulate, thereby keeping the scanning electron beams from being deflected, and ultimately making it possible to measure the pattern of the mask correctly. <IMAGE>

Title: Separating farm slurry
Inventor: MEDDINS C E
IPC: B01D29/60
Filed: 1990-05-11
Abstract: Farm slurry is agitated in a tank 1 and pumped via a two-way valve 7A to a filter 8, from which its liquid content is fed to a tank 3 and its solid content 10 is discharged. The solids content of the slurry in tank 1 is monitored, and if it is too high some liquid is recycled from tank 3 to reduce it, thereby ensuring that filter 8 works efficiently and reducing power consumption. The solids content can be monitored in terms of the torque or power consumption of agitator drive motor 5, or an ultrasonic or infra-red sensor 7C monitors the slurry flowing through pipe 7. If the solids content is high, valve 7A diverts it back to the tank, possibly via a venturi pump 13 to convey the diluting liquid. Level monitors A, B allow the system to work only when tank 1 is sufficiently full, while monitor C actuates an alarm. <IMAGE>

Patent GB-2258051-A (GB)
Title: Determining propagation delays in signal paths
Inventor: PYE RICHARD
IPC: H01L21/66
Filed: 1991-07-24
Abstract: Propagation delays in signal paths leading to respective pins (21,22) in an array of test system pins are determined using a probe which is wiped across the pins. Alternate timing signals (19) and pin identifying signals (18) are applied (20) to each of the signal paths in parallel such that each signal path and the pin to which it is connected receives a different pin identifying signal. When the probe (Fig 2 not shown) is wiped across the pins, it detects the signals on each of the pins and each pin is identified by the appropriate pin identifying signal. The propagation delay in the signal path to the identified pin is then calculated from the detected timing signals e.g. by comparing the timing signals with signals (26) from a clock of a different frequency. <IMAGE>
