Title: Elongate electrical heaters
Inventor: MIDGLEY JOHN ARTHUR
IPC: H01C7/06
Filed: 1983-04-15
Abstract: Elongate electrical devices, comprising two conductors with electrical elements connected in parallel between them, have improved performance if the power supply is connected to one conductor at the near end and to the other conductor at the far end. Particularly useful devices are heaters, e.g. PTC conductive polymer heaters. The power supply is connected to the far end of the device through a connection means whose electrical properties can be correlated with those of the device in order to obtain a wide range of useful results. For example the connection means can have PTC, NTC or ZTC character and can be a simple conductor or another elongate device. The power supply can be DC or single-phase, two-phase or three-phase AC. A circuit of the invention is shown in Figure 3. <IMAGE>
Patent GB-2121898-A (GB)
Title: Vacuum brake booster
Inventor: TSUBOUCHI KAORU
IPC: B60T13/57
Filed: 1983-04-28
Abstract: A vacuum brake booster for an automobile braking system comprises a power piston 12 carrying a control valve piston member 22 that is axially slidable therein to control a pressure differential across the power piston. The control valve member 22 is keyed to the power piston 12 by a key 26 which is of generally W-shaped configuration. A central leg 26a of the key 26 extends through a radial slot 12d in the power piston to straddle a stem portion of the control valve member 22. The outer legs 26c extend around the periphery of the power piston 12 over an angle of slightly more than 180 DEG , and straddle shoulders of the power piston and housing member so that they overlap with the power piston by an amount e and with the housing by an amount f. Strain on the key 26 is thus taken by the outer legs 26c, rather than by the central leg 26a which limits axial movement of the control valve member 22. Actuation of the control valve member 22 is therefore not affected by distortion of the key 26. <IMAGE>

Title: Mesh structures especially for use in television camera tubes
Inventor: PETTIGREW R M
IPC: G03F7/12
Filed: 1983-11-30
Abstract: A first method of making a metal mesh comprises applying a positive photoresist (14, Fig. 1) to a substrate (10) which has a conductive surface (12), applying mask (16) having a mesh configuration over the photoresist, exposing the photoresist which is not protected by the mask, developing and washing away the exposed photoresist to leave the conductive surface exposed in the configuration of the mesh while unexposed photoresist remains in the areas which are to correspond to apertures in the mesh, and electrodepositing mesh material on the exposed conductive surface between the unexposed resist to build up the mesh. A second method of making a metal mesh comprises applying a positive photoresist 34 to a transparent substrate 30, which has a conductive surface 32 applying a mask which has a mesh configuration over the photoresist, with the mesh apertures exposed and the mesh lines obscured, exposing the photoresist which is not protected by the mask, developing and washing away the exposed photoresist to leave the conductive surface exposed in the configuration of the mesh, etching away the exposed conductive surface and removing the photoresist to leave conductive mesh configuration corresponding to the mesh, thereafter applying a negative photoresist 44 to the substrate surface, exposing the resist from the back of the substrate, developing and washing away the unexposed photoresist and electrodepositing mesh metal 48 on the exposed conductive surfaces between the exposed resist to build up the mesh. Using these methods, a mesh can be built up on a substrate which has a flat surface, thereby avoiding the problems associated with prior art methods involving deposition of metal in grooves. In either method it is referrable to apply a release agent such as egg albumen to the conductive surface on which the deposited metal will be built up. <IMAGE>

Title: Automatic exposure control in television cameras
Inventor: PYE ALLAN SYDNEY
IPC: H04N5/238
Filed: 1986-02-08
Abstract: Problems may arise if a small object is being monitored as the exposure may be suitable for the whole scene rather than the object. The invention endeavours to overcome this problem by controlling the exposure of the camera 3 by means of an optical sensor 6 positioned outside the camera which receives light, from screen 4, having substantially the same optical characteristics as the object 1. If number plates of motor vehicles (which may be yellow) are to be monitored the screen 4 is coloured yellow and exposed to the same source of illumination (e.g. the sun 2) as the scene 1. A filter 8, blocking all wavelengths except that to be monitored (i.e. yellow) may prevent overexposure of the camera 3 to light from other parts of the scene 1. <IMAGE>
