Patent GB-2121980-A (GB)
Title: X-ray masks
Inventor: GREENWOOD JOHN CHRISTOPHER
IPC: G03F1/22
Filed: 1982-06-10
Abstract: In semiconductor manufacture, where X-ray irradiation is used, a thin silicon membrane can be used as an X-ray mask. This membrane has areas on which are patterns to define the regions to be irradiated. These regions are of antireflection material 3. With the thin, in the order of 3 microns, membranes used, fragility is a problem. Hence a number of ribs 1 of silicon are formed integral with the membrane, and which are relatively thick, 5 to 10 microns. The ribs may be formed by localised deeper boron deposition followed by a selective etch. <IMAGE>

Patent GB-2108703-A (GB)
Title: Optical-mechanical scanning image display apparatus
Inventor: STAMPER TIMOTHY DAVID JOSEPH
IPC: H04N9/31
Filed: 1982-10-08
Abstract: An image is displayed on a screen by scanning the screen horizontally and vertically with a modulated beam of light, such as laser light, in the manner in which a television picture is constructed. The vertical and horizontal scanning of the light beam may be effected by planar mirrors which are arranged to form the sides of two regular polygons (7, 10). The first polygon (7) is positioned to reflect the light beam (6) received from the laser source (5) and is rotated about its axis at a preselected speed to cause the reflected beam (9) to scan right to light beam (6) received from the laser source (5) and is rotated about its axis at a preselected speed to cause the reflected beam (9) to scan right to left or left to right in a rectilinear path at the desired speed. This reflected beam is further reflected by e.g. the polygon (10) which is also rotated about its axis arranged at 90 DEG  to the axis of the first polygon (7) to provide a further reflected beam (3) which is scanned in a rectilinear path at right-angles to the scanning path of the first reflected beam (9). The apparatus enables large scale images to be produced relatively easily. <IMAGE>

Patent GB-2144290-A (GB)
Title: Measuring system
Inventor: GEE DR ANTHONY EDWARD
IPC: G01S17/32
Filed: 1983-07-08
Abstract: A measuring system 1 for measuring the position and movement of a point within a predetermined plane perpendicular to the plane of the figure and intersecting it at 10 includes optical apparatus for projecting a divergent beam 8 onto the plane. A portion 14 of this beam is reflected by a cube-corner retroreflector 12 whose apex is at the point the position and movement of which is to be measured. The return beam 16 is focussed on a two-dimensional photodetector array 32. The optical system is such that movement of the retroreflector 12 corresponds on a reduced scale to movement of the focussed beam over the photodetector array. A scanning technique is then used to derive the position and movement of the focussed spot and hence of the retroreflector. Three different techniques for improving the speed of operation of the array scanning, compared with scanning the complete frame, are described; one of these (Fig. 2, not shown) involves splitting the reflected beam and projecting each sub-beam onto a linear array via a cylindrical lens. <IMAGE>

Title: Telecommunication exchanges
Inventor: HARLAND GEOFFREY
IPC: H04M7/12
Filed: 1983-08-04
Abstract: In a telephone exchange network which includes a number of analogue exchanges of relatively modern type, e.g. TXE4, fully digital exchanges, e.g. System X, are being introduced. To communicate with these digital exchanges, TDM/PCM junctions (6) extend to the digital exchanges, each being made up of a number of analogue junctions. On these junctions, signalling is done in a common channel manner, using time slot 16 of the 32 channel highway. Access to this channel from the central control equipment (2) of the analogue exchange is under the control of a processor (11), via an interface (4). The interface (4) inserts and extracts call set up data. The supervisory unit (8) inserts and extracts supervisory data. Also described is an arrangement in which the mux equipment is remote from the analogue exchange. <IMAGE>
Patent GB-2124761-A (GB)
Title: Measuring position and/or dimensions of objects
Inventor: RICHTER BRUNO
IPC: G01B11/08
Filed: 1983-08-05
Abstract: A measuring apparatus 1 comprises a laser 2 the output beam 3 of which is incident on a rotating mirror 4 and is thence reflected onto a lens 7 to produce a parallel sideways displacement motion of the beam in a measuring field 8 in which an object P to be measured is positioned. The time of obscuration of the beam in measuring field 8 as mirror 4 rotates is determined and is a measure of the size of object P in the direction of displacement of the beam. The signal from detector 10 is fed to a measuring circuit 12 which is enabled by an enabling signal obtained from a photosensitive detector 15 positioned to receive light reflected back through lens 7 from a partially reflecting plate 16 positioned in the measuring field near lens 7. Plate 16 is inclined at an angle relative to the normal to the beam direction to allow detector 15 to be spaced from mirror 4 in the focal plane of lens 17. An apertured diaphragm 17 can be provided between lens 7 and plate 16 to define the width of measuring field 8.   <IMAGE>

Title: Display panel for TV tube and method of making the panel
Inventor: RIDING FRANCIS BARRY
IPC: B29C69/02
Filed: 1984-08-30
Abstract: The panel for enlarging the image on the faceplate of a TV tube comprises a plate portion (4) having a flat display face (2) on one side, and a plurality of light-conducting rods (3) projecting from the other side and converging to form a concave face (3) on the panel for attachment by adhesive to the convex faceplate of the TV tube. The rods are moulded integrally with the plate portion from a light-transmitting synthetic resin and are clad with a material having a lower refractive index than that of the moulding resin. The panel is formed in a two-part mould (7) with parallel rods and a curved plate portion which is concave on its side remote from the rods. Before the resin is fully set, the panel is removed from the mould and is first dipped in a solution of the cladding material and then placed on a flat surface with the concave side of the plate portion (4) facing this surface. The plate portion (4) is then deflected, for example by sagging, into contact with the flat surface, which deflects the light-conducting rods (5) towards one another so that they become contiguous at their distal ends to form the concave face (3) of the finished panel. <IMAGE>
