Title: Variable colour light source
IPC: G03B27/54
Filed: 1973-12-20
Abstract: 1413435 Light guides; projection printing POLAROID CORP 20 Dec 1973 [4 Jan 1973] 59127/73 Headings G2A and G2J A variable colour light source (10) e.g. for use in a photographic printer, see Fig. 1 (not shown), comprises a plurality of lighting units each providing light of a different colour, e.g. via coloured filters (44, 46, 48) and each receiving light from an individual lamp (36 .... 41) which has means (52, 54, 56) for varying the intensity of the light. Each lamp is optically coupled, through the filters, to the input ends (64, 66, 65) of optic fibre bundles 58, 60, 62 which thus each transmits light of a particular colour to its output end, which is integrated with the output ends of the other bundles to form a mosaic 77 comprising the individual fibres from all the bundles inter-woven in a systematic manner. The fibres in each bundle are randomly arranged, see Fig. 3 (not shown), so that the image of each lamp filament is scrambled during transmission along the bundle. The ground and polished mosaic 77 may form a shallow pyramid, having an apex 84, so that emanating light is dispersed in a wider solid angle. The colour of the composite light emanating from the mosaic 77 is adjusted by operating the means (52, 54, 56). In the modification, Fig. 4a (not shown), two light sources (100, 102) are used, the source (102) having a subtractive coloured filter (110). In another, Fig. 4b (not shown), are four light soruces, of which three have coloured filters.

Title: Circuit arrangement for the low-loss control of a pulse- operated motor
IPC: H02P6/08
Filed: 1972-12-23
Abstract: 1416150 Control of stepping motors ELEKTROMAT VEB 23 Dec 1972 59595/72 Heading H2J A control circuit for a pulse-operated electric motor with phase windings M1-M3 comprises corresponding amplifying systems VS1-VS3, each of which comprises two amplifier V1, V2, and a circuit ES comprising an energy-storing capacitor C1 and a discharging resistor R2 connected in parallel with the motor windings via an OR-gate. Amplifier V1 is actuated by squarewave pulses El and operates with negative feedback to maintain the motor winding voltage at a predetermined value. To reduce the time constant of the leading edges of the square current pulses applied by V1 to the phase winding M1, amplifier V2 operates to apply a higher voltage to winding M1 under the control of a timer ZG which is also fed with the pulses E1. The operating period of the timer may be varied by a variable voltage U3, or the timer may be reset automatically when the supply to winding M1 is switched off. The time constant of the trailing edges of the motor current pulses is determined by capacitor C1 and resistor R2. The outputs of amplifiers V1, V2 are decoupled by diodes Gr1, Gr2.

Title: Water Pollution Monitor and Alarm
IPC: G01N27/22
Filed: 1978-11-03
Abstract: Oil on the surface of water may be detected by a floating monitoring device, comprising a sensing element, connected to an electronic tuned circuit. The operating principle is that of attachment of viscous substances to plastic surfaces forming the outer coverings of metal element conductors. Replacement of water by oil in the space surrounding a pair of elements, causes changes in permeability and dielectric strength, detected as changes in frequency of the tuned circuit oscillator to which they are connected. The frequency of the pollution sensitive oscillator is compared with that of a fixed, reference oscillator over a time interval allowing signal averaging to eliminate spurious alarms. An important feature of the electronic detection circuit is that it may be constructed entirely from Complementary Metal Oxide Semiconductor (CMOS) devices having very low power consumption.

Title: Peak current limiting circuits
IPC: H02H9/02
Filed: 1979-03-06
Abstract: The invention is concerned with peak current limiting circuits for use in a.c. supply circuits susceptible to waveform distortion as a result of excessive peak current demand. Such problems may arise where a standby inverter a.c. power supply is used to feed a supply rectifier having large capacitance.

The inductor additionally has a unidirectional free-wheel current path in the same direction as the load current so that the instantaneous value of the free-wheel current imposes a limit on the maximum value of a peak current. Single phase and three phase arrangements are described. <IMAGE>

Title: Animal feed supplements
IPC: A23K1/00
Filed: 1979-08-02
Abstract: An animal feed stuff supplement is bound together in cake form by a self-setting chemical binding agent, such as aqueous urea-formaldehyde. Feed stuffs such as molasses and cereals, together with additional vitamins and trace elements, salt, and medicinal treatment agents, such as worming compounds, are fed to animals in the form of a bound cake which the animal licks. The binding agent holds the cake together in adverse weather conditions which would cause known supplement cakes to break up. This enables a more controlled dose to be given to the animals without supervision.
