Title: Battery-powered electric vehicle D.C. motor control
IPC: F02B1/04
Filed: 1981-09-17
Abstract: A battery-powered electric vehicle d.c. motor control includes a first potentiometer (17) actuable by an accelerator pedal and a second potentiometer (18) actuable by a brake pedal. The motor current s controlled in accordance with the signals at the sliders of these potentiometers and contactors determine the connection mode of the motor under the control of a comparator (A1004) which is sensitive to the signal at the slider of the first potentiometer (17) only. This causes regenerative braking mode to be selected except when the accelerator pedal is depressed. A resistor (R1001) is connected in series with the second potentiometer (18) to ensure that a minimum braking demand signal is always present, but means (P1002) is provided for cancelling this minimum braking demand signal in certain vehicle operating conditions and further means (P1003) is connected to the comparator (A1004) for overridingly selecting motoring mode in these conditions. <IMAGE>

Patent GB-2089032-A (GB)
Title: Device for Detecting Specific Gravity of Liquid
IPC: H01M50/569
Filed: 1981-10-27
Abstract: In one embodiment of the present invention, a change in the critical angle of total internal reflection is utilized to determine the index of refraction of the liquid to be measured. It is shown that the index of refraction of the liquid is a function of the specific gravity of the liquid. In applications for measuring the state of charge of a battery, the specific gravity is proportional to the state of charge of the battery. A change in intensity of rays intersecting an interface surface indicates the critical angle which is a direct indication of the specific gravity of the liquid and the state of charge of a battery. In another embodiment, a light beam is projected through a transparent medium and then through a portion of the liquid to be measured. A change in refraction due to a change in the index of refraction of the liquid produces a deflection of the beam which is measured by a detector. The magnitude of deflection of the beam is directly proportional to the specific gravity of the liquid and the state of charge of a battery. It is also possible to detect the level of the liquid. <IMAGE>

Patent GB-2091431-A (GB)
Title: Exposure control system for a photographic or television camera
IPC: H04N5/235
Filed: 1981-12-01
Abstract: A pick up element 11 receives light passing through a lens 9 and a diaphragm 10 and converts same to an electrical signal which is amplified by an amplifier 12 and then fed to a level detector 13. A comparator 14 compares the signal level detected by the detector 13 with a reference signal set by a potentiometer, and the diaphragm 10 is adjusted in accordance with the difference between the two signals to achieve automatic exposure control. A hold circuit 16 is operable by means of a switch 17 between a first mode wherein it merely passes onto the comparator 14 the signal from the detector 13 and a second mode in which it holds the signal level from the detector 13 when the switch 17 is activated, thereby locking the exposure. When the exposure is thus locked, manual adjustment of the diaphragm 10 can be performed by means of a potentiometer. The invention is also applicable to ASC exposure systems (Figure 5, not shown). <IMAGE>

Title: Remote monitoring of the position of a member
Inventor: WHITE DAVID GLYNDWR
IPC: G01D5/30
Filed: 1982-02-10
Abstract: To avoid electrical disturbances and fire risks which may occur when electrical position sensors are used, the position of the member is determined using the movement of a spatial distribution of radiation of different wavelengths in response to movement of the member. The radiation is provided by a broad band source such as an array of LEDs 2 and is transmitted along a common optical fibre 4 to the location of a shaft 6. A diffraction grating 7, attached to the shaft 6 to move with it, produces a spatial distribution of radiation of different wavelengths which is collected by an output fibre 10, the wavelength picked up depending on the position of the grating 7, hence the position of the shaft 6 can be determined. Signals front spectrometer 11 comprising a diffraction grating 14 and a CCD array 15 are sent to a controller 17 where they are compared with desired position signals for control of the position of the shaft 6 by means of hydraulic line 18. <IMAGE>

Title: Assembly using ultrasonics
Inventor: TAYLOR FRANK
IPC: H01F41/00
Filed: 1983-02-04
Abstract: A plastics cover plate 6 is assembled to a plastics shell 1, e.g. to form the main portion of a moving coil electro-acoustic transducer of which the shell contains the magnet assembly 2, 3, 4, the plate 6 having a number - six in one case - of inwardly-extending studs 7. The assembly involves placing the cover plate 6 in position when the magnet assembly 2, 3, 4 is in the shell 1, and then applying ultrasonic vibrations and pressure to the cover plate. This causes the studs to collapse around the magnet assembly 2, 3, 4 and the inside of the shell 1, thus effectively locating the magnet assembly in the shell. There is also an energy concentrator 11 on the shell 1, and this, in addition to the function of concentrating the applied energy acts as a seal, since it also collapses to secure the shell 1 and the cover 6 together. Although the method has been described as applied to the assembly of a particular transducer, it should be noted that it is not so limited. <IMAGE>
