Title: Direction indicator system for a vehicle and a trailer
Inventor: PALMER NORMAN HAROLD GEORGE
IPC: B60Q11/00
Filed: 1985-11-22
Abstract: A trailer has direction indicators 18 and 19 which operate synchronously with direction indicators 16 and 17 of a vehicle to which the trailer is attached. Operation of a pilot indicator 20 is controlled by a transistor 23 of a sensor unit 13 in accordance with the voltage drop generated across a monitor resistance 22, such that an L.E.D. 30 emits light whenever the trailer indicators 18, 19 are energised. Fluctuations in this voltage drop are smoothed out by a smoothing circuit formed by a capacitor 28 and a resistor 24, and a diode 29 is connected in parallel with the monitor resistance 22 to reduce the initial voltage peak across the latter. A series resistor 31 integrated with the L.E.D. 30 protects the latter from damage in the event that full battery voltage is applied across the indicator 20, and a further series resistor 32 protects the transistor 23 in the event of the output terminal 21 of the sensor 13 being shorted to earth. Where a sensitive L.E.D. 30 is used, a resistor may be connected in parallel with the indicator 20 to prevent it glowing due to leakage current through the transistor 23 when only the vehicle lamps 16, 17 are connected. <IMAGE>

Title: Method and apparatus for optically testing the ends of rod-shaped articles of the tobacco processing industry
Inventor: RADZIO ANDRZEJ
IPC: A24C5/34
Filed: 1986-06-11
Abstract: Cigarettes 3 whose ends 3a are to be tested for density, the presence or absence of cavities and/or other defects are transported by a peripherally fluted drum-shaped conveyor 1 sideways past the narrow slit-shaped aperture 9 of a stationary diaphragm 11. Radiation from a light source 13 is conveyed to the aperture 9 by a first bundle 16 of fiber optics, and a second bundle 17 of fiber optics conveys reflected radiation from the aperture 9 to a transducer 14 which transmits signals to an evaluating circuit 18. The aperture 9 is surrounded by a surface 7 which contacts the ends 3a of cigarettes 3 during testing of the respective ends to ensure that such cigarette ends are located at an optimum distance from the uniformly distributed ends of the first and second bundles 16, 17 in the aperture 9. The evaluating circuit 18 integrates the signals generated during testing and the integrated signals are modified 24 as a function of the selected speed of the conveyor. <IMAGE>

Title: Generating a coherent beam of bosons
Inventor: LO SHUI-YIN
IPC: G21K1/00
Filed: 1986-07-25
Abstract: A macroscopic baser (boson equivalent of a laser). Bosons such as deuterium particles generated by an ion source (2) are injected into a vacuum tube (1), so as to execute motion on a circulatory path therein. Movement of the bosons in this path may be effected by the use of bending magnets (3) and (4) and focusing of the bosons into a circulating stream is assisted by quatropole magnets (5) and (6). A coherent light beam from a laser is directed into the stream of bosons within the vacuum chamber to effect induced scattering of the bosons within that stream whereby to cause the stream to develop as a coherent beam of bosons which is directed outwardly from the baser by suitable deflection of the circulating stream, such as de-energization of the bending magnets. In other embodiments, the bosons may be reflected in linear fashion.

Title: Switch actuator of variable orientation
Inventor: RAYBOULD MARTIN JAMES
IPC: H01H13/70
Filed: 1987-06-26
Abstract: A membrane-type electrical control panel has a switch (5) beneath a membrane cover (3) and a switch actuator button (7) which is operable through the membrane. The actuator button is preferably in the form of a prism having a triangular or other cross section and, in a first orientation (see Figure 1b), extends through a complementary aperture (6) in a frame member (1) to operatively engage the switch (5). At the mouth of aperture (6) the frame member comprises a recess (8) for retaining the button (7) in a second orientation (see Figure 2b) flush with the frame member out of operative contact with the switch, hence disenabling the switch. Thus, the button may be stored under the membrane (3) within the control assembly so that it can be reused for enabling the switch subsequently, if required. <IMAGE>

Title: Controlling a video recorder by a coded broadcast signal
Inventor: BLAXTAN PETER WILLIAM
IPC: H04N7/16
Filed: 1988-03-22
Abstract: A control system for a video recorder involves the transmission of numerical codes associated with different programmes and the generation of control signals for turning the video recorder on and off in response to detection of predetermined numbers in the received television signal, whereby predetermined television programmes may be recorded without the need for setting into the video recorder the date and time at which the programmes are expected to be received. The decoder unit includes an infrared transmitter which transmits the received numbers to a remote control unit which compares the received numbers with prestored numbers representing the programme to be recorded and transmits a start instruction, by infrared, to a video recorder when the received and prestored numbers match. The remote unit is programmable to render it compatible with different video recorders. The apparatus may include a decoder unit which has means for descrambling encrypted television signals and means for extracting the programme numbers from the received signal. <IMAGE>
