Title: Electrical signal transmission
IPC: G08B21/04
Filed: 1981-10-28
Abstract: A system for transmitting and receiving electrical signals employs a receiver (5 to 8) having a loop aerial (4) extending around a space in which signals are to be received. A transmitter produces inductive signals which can be picked up by the receiver within the space bounded by the aerial. This system can be used to monitor the activity of a person by connecting the transmitter to a sensor, such as an arrangement of mercury switches, so that recurrent signals are transmitted during normal activity of the person. Departures from such normal activity give rise to changes in the pattern of transmitted signals which can be detected by the receiver. <IMAGE>

Title: Improvements in power- operated boosters
IPC: B60T13/14
Filed: 1982-01-08
Abstract: An hydraulic booster has a housing (1) with a bore (2) in which a boost piston (4) works. Pressurisation of a boost chamber (8) by fluid from a pressure source under the control of valve means (9) advances the boost piston (4) to augment a force applied to an input member (5). The augmented force is transmitted to an output member (7) which acts on a master cylinder (74) of a braking system. The output member (7) works in a bore (13, 100) in the boost piston (4) and is movable relative to the boost piston (4) in response to pressurisation of an auxiliary chamber (14). Initial movement of the input member (5) causes the valve means (9) to pressurise the auxiliary chamber (14), moving the output member (7) relative to the boost piston (4) through a distance determined by limiting means (15), to take up the lost-motion in the system. On further movement of the input member (5) the output member (7) and the boost piston (4) move together in response to pressurisation of the boost chamber (8). The limiting means (15) may be an auxiliary valve (16) or a stop member (103) on the boost piston (4). <IMAGE>

Title: Detecting surface defects
Inventor: WEST ROBERT NOEL
IPC: G01N21/47
Filed: 1983-03-03
Abstract: A method and apparatus for detecting discontinuities in a radiation diffusing surface 100 in which radiation from the surface is collected 118A 119A from an angle 123A other than normal. In one arrangement, used to detect creases, if no creases are present, then according to Lambertian law, the maximum radiation will be radiated normal to the surface 100 and so if there are creases in the surface there will be an increase or decrease in the amount of radiation radiated at that angle  delta  to the normal. In an alternative arrangement, used to scan an image on a sheet which might include discontinuities 101 in the sheet, the above method is applied in two separate directions 123A, 123B, and the signals from the two separate directions compared 121, the signals being passed if they are identical or substantially identical and being attenuated if they are different. <IMAGE>
