IPC: F21V19/00
Filed: 1982-07-15
Abstract: A vehicle light assembly includes several incandescent lamps which are inserted in lamp holders of a plastics supporting member (35) and rest with their cap (31) against bent lugs (25) near to the lamp holders, which lugs are punched from a steel sheet billet in the same way as a common first lead (16) for several incandescent lamps and at least one further lead (11, 12, 13, 14, 15) for each incandescent lamp.

Title: Electronic sleepmaker
Inventor: WILLIAMS CARADOC
IPC: A61M21/00
Filed: 1982-07-26
Abstract: An electronic instrument for promoting sleep, by relaxation rhythms induced through the eyes or ears into the nerve system. Sleep is induced through the use of a earpiece, providing low level audio tones, intermodulated at very low frequency and adjusted by the user to sustain a comforting bio-rhythm. Alternatively, a very low intensity modulated light is used to induce a rhythm through the closed eyelids. The earpiece or light is conveniently located on the head pillow and the outputs are normally used separately or they may be used together. The instrument is powered by two small self-contained batteries and may be used for many hundreds of hours without appreciable battery power loss.

Title: Arrangement for determining the value of AC power or AC consumption energy
Inventor: HALDER MATHIS
IPC: G01R21/00
Filed: 1984-11-16
Abstract: A multiplication product consisting of voltage and consumption current and produced by means of a first multiplier (1) normally includes, as an alternating error component, a term of angular frequency 2 omega . That term causes an error which cannot be disregarded on a percentage basis when making short- term measurements. In order to eliminate that error and thus permit accurate measurement values to be rapidly determined, the voltage and the consumption current are also additionally phase-shifted by means of respective phase shifters (4,5) through angles (90 DEG - alpha ) and (90 DEG + alpha ) respectively, and are then multiplied together by means of a second multiplier (2) to form a second multiplication product. The two multiplication products are finally added together by means of an adder (3) to eliminate the alternating error component. Fig. 3 shows a modification wherein error components are removed from a three-phase power meter. <IMAGE>

Title: Multiple loop feedback systems
Inventor: MILLER GARY
IPC: G05B6/02
Filed: 1985-01-09
Abstract: A multiple loop feedback system arrangement as typically shown in the diagram which may be used to construct a control system, electronic amplifier or electronic regulator. The input signal combiners G1(s) and G2(s) are selected to be either summing, summing inverting or differential and G3(s) is selected to be either inverting or noninverting so that the signal loop formed by G1(s), and G2(s) has a net phase shift of zero degrees and the signal loop formed by G1(s), G3(s), B(s) and G2(s) has a net phase shift of 180 degrees. By setting the gain of the zero phase shift loop to unity a balanced condition occurs where the error signals generated in G3(s) do not appear at the output  theta o. Other embodiments of this invention include an arrangement where the input of G3(s) is coupled to the output of G2(s). <IMAGE>
Patent GB-2169398-A (GB)
Title: Optical sensors
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G08B13/18
Filed: 1985-01-09
Abstract: A leaky optical fibre is used to radiate light into the environment and the radiated light is detected at one or more places along the fibre. Smoke or an intruder, for example, blocking the transmission path between the fibre and a photodetector will produce a loss of photocurrent which can be used to trigger an alarm. The same principles can also be employed in a spectrometer, since for example, different gases absorb at different wavelengths.

Title: Multi-input electrical switch
Inventor: GRANT JOHN T
IPC: H01H3/46
Filed: 1985-03-29
Abstract: A personal attack or panic switch such as used in security systems in which an actuator (22) is displaceable to a switching position in response only to two or more operating devices such as push buttons (12, 14). The operation of one button only, produces insufficient (or no) displacement of the actuator (22) to reach the switching position. The switch is less susceptible of accidental operation since to effect switching two (or more) buttons have to be depressed simultaneously, or successively i.e. one is depressed while the other(s) is (are) held down. In the preferred embodiment the actuator (22) carries a magnet into or out of close proximity with a magnetic reed switch, the actuator (22) including a linkage (50) having portions that are flattened by respective pushbuttons (12, 14). <IMAGE>
