Patent GB-2020215-A (GB)
Title: A Method of Rolling Angular Sections
IPC: B21B1/08
Filed: 1979-05-08
Abstract: An angular metal section is produced by rolling a rectangular elongate metal blank to form a lengthwise triangular ridge having an apical angle equal to that at which flanges of the section are to be set with respect to each other, and bending portions of the blank about this apical angle to form the flanges. The triangular ridge is formed by rolling from a rounded protuberance previously rolled on the blank. In each rolling pass, the thickness of the blank is reduced by about one third.

Title: Lighting control systems
IPC: H05B37/02
Filed: 1979-07-02
Abstract: In a system for controlling an array of lamps arranged in rows or columns or concentric circles, solid state switches e.g. triacs may be connected in links connecting the live terminals of the lamps to a live bus bar and the neutral terminals of the lamps to a neutral bus bar. Control circuits are provided for selectively closing the switches so as to produce different patterns of illuminated lamps. Where the number of lamps exceeds the number which can safely be connected to the power supply the system is programmed so as to eliminate any possibility of connecting more than the safe number of lamps to the bus bars at any particular time. By switching from one set of lamps to another very rapidly, the visual effect of all lamps being used can be obtained. A pulse generator can be used to run through a programme of lamp connections from a memory. Alternatively the amplitude of an electrical signal derived from an audio source can be used to vary the production of control pulses.

Patent GB-2046467-A (GB)
Title: Holographic digital data recording
IPC: G11C13/04
Filed: 1980-03-12
Abstract: Pages of digital data, e.g. 50 to 100 bits each, are recorded as holograms formed by modulating individual digit- beams of coherent light, combining the digit-beams and a reference beam and scanning the holograms relative to a film to record each hologram in a different position. The digit beams pass simultaneously, parallel to each other through a page composer where they are modulated. In order to keep the spatial frequency bandwidth of the holograms low with low variance in the light intensity distribution at the hologram plane, the digit beams (squares with crosses) are clustered around the reference beam axis (open square) so as to be irregularly arranged in two coordinates in all four quadrants and with no point symmetry between beam pairs. The Figure shows a 50-beam arrangement with digit-beams of cross- sectional dimension d at a minimum pitch of 2d and randomly located on a grid of points defined by the (x,y) coordinates 2(m+1 DIVIDED 2)d, 2(n+1 DIVIDED 2)d, where m.n are integers. The beams are preferably converged through a focus where a field stop delimits the radiation, allowing close hologram packing on the film. The scanning movement is compounded of continuous film movement and transverse deflection of the combined beams by an electro-optical device, which moves the image position stepwise, allowing use of a continuous wave laser as the coherent light source.   <IMAGE>

Patent GB-2118208-A (GB)
Title: Method of making an alloy
Inventor: MEETHAM GEOFFREY WILLIAM
IPC: B22F9/10
Filed: 1982-03-31
Abstract: In a method of making an alloy in which superior cyclic properties may be achieved by avoiding the presence of oxide inclusions and of Titanium Carbo-Nitride stringers, the alloy constituents are first melted in a way which avoids contact with the refractory material from which the oxide inclusions normally derive, for example, by electron-beam melting in a water-cooled copper crucible in a vacuum or protective atmosphere. The thus formed alloy is then powdered, again in a refractoriless process, by melting the end of a spinning ingot, so that the physical separation of the powder particles prevents agglomeration of the stringers. The clean powder is finally consolidated. <IMAGE>
