Patent GB-460181-A (GB)
Title: Improvements in and relating to roentgen-ray tubes
IPC: H01J35/14
Filed: 1935-05-20
Abstract: 460,181. R÷ntgen-ray tubes. AJKAY, F. R., and BITTERA, J. May 20, 1935, No. 14743. Convention date, May 19, 1934. [Class 39 (i)] A R÷ntgen-ray tube is provided with means for producing a magnetic field in such a manner that the path of the electron stream can be moved when desired laterally and relatively to the anticathode to change the position of the focal spot or portion of the anticathode on which the stream impinges. The focal spot can be changed before the surface of the anticathode becomes overheated or damaged. The magnetic means may be an uncored coil e surrounding the tube, or electromagnets or permanent magnets. The movement of the spot may be performed by adjusting the magnetic means in a suitable mounting, or by varying the direct current through a coil. The size of the focal spot can be varied at the same time. Specification 460,270 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of a curved anticathode c1, Fig. 3 (Cancelled), which is struck by electrons uniformly over its surface. R÷ntgen rays emitted nearly normally to the surface pass through an apertured diaphragm f situated at the centre of curvature. The cathode may be heated by induction, as described in Specification 460,270. A magnetic velocity selector may be employed in gas-filled tubes, so that electrons of only one velocity reach the anticathode. The anticathode may be rotated by the action of the electron stream, and, as described in Specification 460,271 a magnetic brake may be used to control the rotation. This subject-matter does not appear in the Specification as accepted.

Patent GB-902719-A (GB)
Title: Methods for producing fine metal powders
IPC: B22F9/30
Filed: 1957-07-15
Abstract: Fine metal powder is prepared by a process which includes producing a metal vapour by vacuum evaporation or electrical discharge and subjecting the vapour to such conditions and vacuum or low pressure that it is condensed as a fine powder.  The metal vapour may be formed by evaporation of the metal by means of an electrically-heated, heat-resistant filament, boat or crucible, by subjecting the metal in the form of a filament to an electric discharge, or by subjecting the vapour of a compound of the metal to an electrical discharge.  In the second method a metal wire and an electrode are included in a charging circuit and the distance between them is reduced until discharge occurs.  In the third method vapour of the metal compound, with or without a reducing gas, may be passed through a space between electrodes which are included in a charging circuit.  This method, in an example, is applied to the production of titanium powder from a vapour of titanium tetraiodide.  The metal may be condensed as powder by passing the vapour into contact with an inert gas at low pressure, or by passing a stream of inert gas into contact with the vapour.

An escapement for. a spring-driven predetermined counter comprises a pair of levers 17, 18 lifted alternately by cams 27, 28 to permit rotation of a numeral wheel 29 with ratchet teeth half a step each time. The required number of operations of a machine such as a copier is set by rotating the numeral wheel 29 clockwise so tensioning a spring 6 Each operation of the machine rotates cams 27, 28 through 360 degrees, so lifting arm 17 then arm 18. Ratchet wheels 12, 13 are thus freed alternately and the numeral wheel makes a complete step. As the numeral wheel turns from 1 to 0, cams 93, 38 lift arms 17, 18 free of the ratchet wheels and the numeral wheel is driven smartly by the spring so that projection 35 strikes arm 40, which rings a bell 39 and acts as a stop. In a modification, Fig. 4; the numeral wheel drives the escapement through a toothed clutch 69, 70. The numeral wheel is normally adjusted by manual rotation and pressure against spring 63, but over-adjustment is readily corrected by the yielding nature of the clutch.

Abstract: 1305993 Monitoring processes T TSUGAMI 2 April 1970 [11 April 1969 (2)] 15779/70 Heading G4H In a data processing system for use with a number of production machines, the system distinguishes the particular workpiece being operated upon and feeds the data via a processing unit to a computer in which various parameters connected with the production process such as machine operating time, may be determined. The workpiece being machined by machine tool M1 at a given time, is identified either by the setting of a rotary switch by the operator, or from the control tape for a numerically controlled machine. The code instruction from M1 operates switches C1 which in turn control the output of voltage divider unit B1 which is fed with D.C. power from A. The units C1, B1 comprise a digital to analogue converter which consists of a number of resistors arranged in the form of a ladder (see Fig. 13). The output from units B1 is a voltage level whose value is indicative of the workpiece. This voltage is fed via gates g1 through channel ch1 to gate v1. Gate g1 is open whenever a D.C. voltage is present on one input and whenever a signal from machine M1 is received on the other input. Gate vl is opened by a signal on terminal 3 derived from ring counter 2. The ring counter 2 operates in response to clock pulses generated by pulse generator 4 so that the gates vl, v2 ... vn associated with various machine tools are opened in turn. The output of gate v1 thus comprises a pulse whose voltage height is indicative of the workpiece being operated upon. The pulses from the various machine tools pass through an analogue to digital converter G. The output from G is fed to a code converter H which changes the code into a form suitable for use with a computer. The output of H is fed via an amplifier I to magnetic recording head K and tape punched unit J. Magnetic tape p or punched tape n then carries the information to computer L.
