Title: Improvements in control systems for x-ray tubes
IPC: G05F1/42
Filed: 1946-12-12
Abstract: 629,619. Automatic control systems for X-ray tubes. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 12, 1946, No. 36726. Convention date, Sept. 20, 1945. [Class 38 (iv)] In a control system for stabilizing the exciting current of an X-ray tube, the cathode heating current is varied, by means of a saturable reactor, in correspondence with changes in the exciting current. As shown, the X-ray tube 5, is supplied from the high voltage transformer 9 and rectifiers 7, 13, with D.C. exciting current which passes through the potentiometer network 40 to produce a proportionate D.C. voltage on the grid of valve 37, the anode current of which excites the control winding of the saturable choke 35. The latter is in series with the A.C. heating supply to the tube cathode which is therefore varied in accordance with changes in the exciting current. By control of the screen-grid voltage of tube 37 the X-ray tube filament current is automatically raised at the commencement of an exposure and reduced at its termination. Instability due to feed-back between the filament and the exciting circuit is precluded by the damping transformer 74 which injects a stabilizing voltage into the grid circuit of 37. The control circuit is not operable until after a time delay, i.e. the time taken for the cathode of rectifier 60 to rise in temperature. Reference has been directed by the Comptroller to Specification 636,357.

Title: Improvements in or relating to coherent dispersion hardened composites
Inventor: PERONA GIOVANNI
IPC: B23K20/00
Filed: 1968-08-05
Abstract: 1,216,387. Composite metal components. G. PERONA. 5 Aug., 1968 [18 Oct., 1967], No. 37239/68. Heading E1K. [Also in Division B3] A coherent dispersion hardened composite material comprises a plurality of layers of a basic material, or of parallel wires of the basic material diffusion welded to one another with the interposition of a substantially uniform layer of a metal or a metallic compound capable of preventing the movement of dislocations in the basic material, the thickness of the layers or the diameter of the wires being about 1 micron. Fine aluminium wires are passed through a furnace with controlled temperature and atmosphere to form a surface oxide layer. Aluminium is then plasma sprayed to form a second layer and the wires are formed into a bundle, which is inserted in an aluminium tube having an oxidised inner surface. The assembly, which has an overall diameter of 4cm is reduced to 2mm diameter by rolling at 600‹C and finallly reduced to 0.5mm by drawing. The bundle of wires is compacted by diffusion welding and the oxide layer inside the tube acts as a stopweld. The tube is then removed by etching. In an alternative embodiment, the interior of the tube is only slightly oxidised and the wires are partially welded thereto. The tube remains on the wires and the assembly is heat treated after reduction. Tubes are made by forming alternate layers of axially directed wires and helically wound wires on a bar, the assembly being heated to diffusion weld the wires together. Sheets are made by assembling the coated wires into layers and the wires in adjacent layers may lie at .right angles to each other. Alternatively, starting with sheet material, this is coated with material for preventing dislocations, a plurality of sheets being stacked together and hot rolled. Wire is made by rolling up a coated sheet, which is then rolled or drawn a number of times to the required diameter.

Title: Improvements in or relating to tachographs
Inventor: REIGGER PAUL
IPC: G01P1/12
Filed: 1956-12-06
Abstract: 816,127. Speedometers; recording apparatus. KIENZLE APPARATE G.m.b.H. Dec. 6, 1956, No. 37323/56. Classes 106 (3) and 106 (4). A tachograph carrying a record sheet on which the speed of the vehicle is recorded comprises a first driving means for rotating the record sheet at a slow rate during the normal operation of the vehicle, and a second fast-driving means that can, when desired, by manually brought into operation when the vehicle is accelerating or retarding so as to give a large time base to the record of the acceleration or retardation. A second marking means is adapted to indicate over what portions the time base has been increased. In Fig. 1 one end of a spiral spring 4 is coupled to a shaft 5 on which is freely mounted a disc 7 for supporting the record shaft, the speed of the shaft 5 being controlled by gear means 11 cooperating with a conventional clockwork escapement mechanism that is not illustrated. A spring-pressed ball 8, Fig. 2, interconnects the shaft 5 and the disc 7 so that when the shaft 5 turns in the direction a the disc 7 is forced to turn with it but if the disc 7 is rotated in the direction " a "by the second driving means at a speed greater than that of the shaft 5 then it is free to do so. The other end of the spiral spring 4 is coupled to its housing 3 which is rotatable about the shaft 5 to drive a chain of gear-wheels geared to the disc 7. This chain of gear-wheels is normally held against rotation by means such as a displaceable pin 27, Fig. 2, extending into a hole in one of the gear-wheels. Ratchet means are provided in this gear-chain to permit the disc 7 to be rotated by the shaft 5 even though the gear chain is locked by the pin 27. When the pin 27 is displaced this gear chain is driven by the spring 4, and controlled by an escapement mechanism 23-25, such that the disc 7 is rotated at a speed greater than that of the shaft 5. Figs. 4 and 5 show an arrangement in which when a brake pedal 40 is depressed to slow down a vehicle, a part 42 thereon automatically displaces the pin 27 to allow the speed of the record sheet to increase. At the same time electrical contacts 46, 47 are closed to cause a solenoidoperated marking means 51 to engage the record sheet and draw a line 58 to indicate over what portion of the record sheet the velocity line 59 is drawn to a different time base. In an alternative construction a fluid-pressure circuit responsive to the operation of a brake of the vehicle closes a switch to cause a second marking means to move from an idle position to a second position to indicate over what period the record sheet was rotated at the higher speed.
