Title: Improvements in or relating to the manufacture of grid electrodes for electric discharge devices
Inventor: GAGER PETER GEORGE GRANT
IPC: H01J19/00
Filed: 1957-04-10
Abstract: 822,972. Making grid electrodes; brazing. M-O VALVE CO. Ltd. April 10, 1958 [April 10, 1957], No. 11759/57. Classes 83 (2) and 83 (4). [Also in Group XI] In making a grid electrode for an electric discharge device, the wires of the electrode are soldered to a supporting frame 1 by eddy current heating, the expansion of the wires being arranged substantially to match that of the frame, at least at the time when the supply of heat ceases, by virtue of heat radiated and/or conducted to the wires from a metal body disposed adjacent the frame so as to be heated by the eddy current heating.

Title: Methods and apparatus for checking measurements made in image  analysis systems
IPC: G01N15/14
Filed: 1971-04-28
Abstract: 1392442 Image analysis IMAGE ANALYSING COMPUTERS Ltd 21 April 1972 [28 April 1971 18 May 1971 (2)] 11823/71 15677/71 and 15678/71 Heading G4D [Also in Division G1] A line scanning image analysing apparatus for examining surface faults in sheet metals is provided with means for inserting a standard test field, for comparing measurements made on the field with the same measurements made when the apparatus is known to be operating correctly and for operating an alarm if incorrect operation is indicated. A sheet of metal 10 is moved about by electric motors (not shown), so that small fields 104 are successively viewed by a television camera; the video signal is converted to a binary signal at 46; a counter 54 counts clock pulses during each intercept to indicate the area covered by the surface faults; a counter 80 counts the number of intercepts: and a counter 90 counts the number of surface faults, all in conventional fashion. When the sheet 10 has been fully scanned (e.g. after 500 small fields 104 have been examined), a mask 14 is moved so that the camera sees a test field 100 and comparators 56, 82, 92 compare the resulting output of the three counters 45, 80, 90 with the correct values, d, n 1 , n 2  stored in shift registers 59, 85, 95. (The correct values of a new standard can be read into registers 59, 85, 96 by changing over switches 55, 55<SP>1</SP>, 81, 81<SP>1</SP>, 91, 91<SP>1</SP> to connect the registers to the counters). If the comparators detect a significant difference a signal appears at 62 to operate an alarm or to alter in some way a print out of test results, e.g. the printout may change from black to red to signify that the results may be erroneous. During examination of a sheet the comparators are used to set limits to the measured values. Various limits can be selected by switches 57, 83, 93 and the alarm signal 62 will again appear if the limits are exceeded. The apparatus may for instance reject any fields 104 such as 112 which intersect the mask 14; normally the surface faults occupy only a few per cent of the surface area of the metal but the mask would cover a much larger portion and operate the alarm. A scratch on the metal surface (Fig .4, not shown), will produce an excessive number of intercepts while rust on the surface will produce a very large number of small faults and these conditions can be indentified by comparators 82, 92 respectively. Specification 1,324,323 is referred to.

Title: Microwave transmission line
IPC: H01B7/00
Filed: 1953-05-01
Abstract: 761,764. Transmission line arrangements. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1953 [May 8, 1952], No. 12113/53. Class 40 (8). The lateral extent of the dielectric layer in a microwave strip transmission line is adjusted to promote propagation of the TEM mode with minimum loss. The transmission line is of the type described in Specifications 704,050 and 708,601 and comprises two conductors 1, 2 printed or otherwise disposed on either side of a dielectric layer 3b a small fraction of a quarter line-wavelength thick. It is shown in the Specification that coupling with undesired modes of propagation can be minimized by making the dielectric layer 3b, Fig. 4, extend to either side of the line by a distance #e/2, where #c is the free-space wavelength in the dielectric. The same object may be achieved (Fig. 5) by making the lateral extent equal to #s/2, where #s is the wavelength of TM mode surface waves propagated parallel to the surface of a plane conductor coated with a thin layer of dielectric. For practical purposes #s=#o, where #o is the free-space wavelength. In this case the conductor 2a is arranged to extend the full width of the dielectric. In a further arrangement (Fig. 7) the dielectric extends for a distance #s/4 and is provided with conductive coatings 14 on its outer edges. In a modification of this arrangement the conductor 2b extends to the outer conductive edges 14. The same effect can be obtained where the lateral extension equals #e/2 by replacing the conductive strips 14 by strips of ferrite material. Fig. 10 shows an example of a double line based on the arrangements shown in Figs. 5 and 7. A multiple line may be formed by arranging dielectric layers on either side of a tubular copper braid 21 forming a common conductor for the inner and outer lines 23, 27. The spacing of the lines is similar to that shown in the arrangement of Fig. 10.

Title: Towing winch
IPC: B63B21/56
Filed: 1972-03-15
Abstract: 1343750 Winches E A PETERSON 15 March 1972 [12 Aug 1971] 12120/72 Heading B8B [Also in Division F2] A towing winch 10 mounted on a towing vessel 11 for towing a member 14, includes a cable drum 12 driven through a continuously slipping clutch 16 whose torque transmission is controlled in response to the tension in the towing cable 13 to maintain a predetermined tension value, the interval between the vessel 11 and member 14 also being automatically maintained through the tension controlling arrangement. The clutch 16, having a power input from a unidirectional multi-speed motor 15 comprises water-cooled slipping friction discs whose degree of frictional engagement is controlled by an inflatable annular air bag having its air supply pressure controlled by a cable tension measuring apparatus 20. The latter 20 comprises three sheaves between which the cable 13 runs, the centre sheave being associated with an hydraulic load cell producing a signal corresponding to the cable tension, the signal passing to a transducer from which corresponding air signals are transmitted to be compared with a manual pre-set pressure and any deviation causes increased or reduced friction in the clutch to change the drive torque of the winch until the system is again balanced. When the interval between the vessel 11 and member 14 has been manually established, a clutch on the apparatus 20 is engaged to cause a potentiometer to be driven by one of the sheaves to indicate linear displacement of the cable 13 and therefor change in the interval. Movement from a zero position of the potentiometer, causes a mechanical change in the presetting valve of the tension regulating system, whereby the cable 13 is payed in or out until the zero position is again reached with the associated pre-set interval.
