Title: Method and apparatus for reproducing television images from a  video signal
IPC: H04N5/74
Filed: 1972-01-11
Abstract: 1320292 Cathode-ray display tubes EIDOPHOR AG 11 Jan 1972 [12 Jan 1971] 1326/72 Heading H1D [Also in Divisions H3-H5] A cathode-ray tube for a television display of the type wherein the electron beam is used to produce local deformations in a target electrode so that it variably deflects an incident light beam on to a display screen, uses a plurality of beams and a focusing system which makes the beams overlap on the target to an extent which is controlled by an input signal. In Fig. 2 the beam emanating from a cross-over point 1 is split into three beams by an apertured diaphragm 3. A main lens 5 focuses the three beams into a single line image on the deformable screen 19; an auxiliary quadrupole lens 4 energized by the input video signal acts in opposition to the main lens and when fully energized causes the three beams to form three adjacent line images and thereby produce a larger total deformation area. The charge density in each of the three areas should be equal, so the centre aperture may be narrower (Fig. 4, not shown) or split into two discrete parts (Fig. 5, not shown). The lenses may both be magnetic or electrostatic.

Abstract: 871,188. Paralleling A.C. machines. PARSONS & CO. Ltd., C. A. Dec. 10, 1958 [Jan. 15, 1958], No. 1413/58. Class 38 (4). A method of allowing an alternator uncoupled from its prime mover to operate as a synchronous condenser for a supply system employs an auxiliary generator which is connected to the alternator to bring it into synchronism with the supply system. The alternator 1 is uncoupled from its turbine a through a coupling 6 and is connected through switches 7, 8 and auxiliary bus-bars 3a to a generator 9 driven by a motor 10. The turbo alternator turning gear then rotates the alternator to which the excitation is applied, and excitation is also applied to the generator either at the same time or when the alternator is rotating, hence causing the generator also to rotate. The motor 1 is then energized to bring the machines 1, 9 to the supply synchronous speed, when the alternator 1 can be paralleled to main busbars 3 and the generator disconnected. The motor 10 may be of the asynchronous type with gearing, or the generator 10 may have two more poles than the alternator 1 to ensure that synchronous speed is reached.

Title: Improvements in and relating to gas turbine plant
IPC: F02C3/13
Filed: 1933-01-18
Abstract: 413,697. Gas turbine plant. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and FORSLING, B. E. G., Highcroft, Ashlawn Road, Rugby. Jan. 18, 1933, No. 1690. [Class 110 (iii).] In a gas turbine plant comprising at least two turbines on separate shafts, one driving the air compressor and the other producing power, means are provided outside the gas cycle whereby the distribution of power between individual shafts can be altered or power transmitted from one shaft to another. In the arrangement shown in Fig. 2, an electric generator 5 is driven by a main gas turbine 4, and an air compressor 1 by an exhaust gas turbine 6. This turbine is aided by a variable-speed electric motor 9 which, on starting, is supplied with current from an external source. The compressed air passes through a preheater 7 to a combustion chamber 2 where products of combustion are formed and mixed with unburnt air and then used partly in the turbine 4 and partly for reheating the gases in the interstage pipe 20 as described in Specification 412,970. In a modification the turbines 4, 6 work in parallel, and in a further modification one turbine of the double-rotation type is used, one of the shafts driving the generator and the other driving the compressor with the aid of an electric motor. The aiding motor may be a steam turbine. In Fig. 4 the waste heat of the combustion products generates steam in a boiler 18. This steam is used in two turbines 20, 21, mounted respectively on the shafts of the compressor 1 and the main turbine 4. Air from the compressor 1 passes through a preheater 7 to the combustion chamber 2 and the products pass in series through the main turbine 4, a reheater 30, the compressor turbine 6, the preheater 7, the furnace of the boiler 18, and an economizer 19. The steam turbine 20 is governed by a speed governor 23 and the turbine 21 by a pressure governor 24. On starting up, steam from an outside source may be supplied to the turbine 20, or the furnace of the boiler 18 may be independently fired.
