Title: Glow-Discharge Character-Display Tube and Method of Manufacturing such a Tube.
IPC: H01J17/48
Filed: 1967-10-23
Abstract: 1,191,466. Glow discharge tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Oct., 1967 [26 Oct., 1966], No. 48028/67. Heading H1D. In a glow-discharge character-display tube having a number of electrodes 0<SP>1</SP>-9<SP>1</SP> in the form of characters arranged one behind the other, each character electrode is of chromiumnickel-steel alloy and is secured directly to a corresponding lead-in wire sealed through the base 17 of the tube and is supported by it. The lead-in wires extend through a mica centring plate 19 which is shielded by a metal plate 20 supported by two further lead-in wires (11 and 14, Fig. 2, not shown), and the character electrodes are preferably stud-welded to the ends of corresponding lead-in wires which are preferably of the same material. For shockresistant arrangements the character electrodes may be provided at their upper ends with lugs (not shown) secured in an insulating rod (not shown) which serves only to connect the electrodes together. An additional character electrode (25, Figs. 2 and 3, not shown) in the form of a full stop is preferably formed of a material of lower work function, e.g. iron or molybdenum, so that it will glow sufficiently brightly without using a higher voltage. A lead-in wire 15 has its end projecting above the plate 20 and is connected by a high resistance to the cathode supply voltage so that it does not glow but pre-ionizes the gas to increase the ignition speed of the characters. An anode (Fig. 1, not shown) is welded to the plate 20 and at its upper end carries a sheet metal support for a glass tube (23, Fig. 3, not shown) containing mercury. The metal support may be heated inductively or by radiation to release the mercury after the tube has been sealed.

Abstract: 1279449 Ion beam apparatus HUGHES AIRCRAFT CO 30 Sept 1969 [4 Oct 1968] 48059/69 Heading H1D In an ion implantation apparatus those ions which are divergent from the ion beam axis are removed from the ion beam 18 after passing through a mass separator 20 by passing it through a small aperture 30 in a filter 28, between which and the mass separator 20 is disposed a decelerating electrode 26 to minimize sputtering of the apertured plate 28, so that the reduced ion beam may subsequently be focused to a spot on a target 20. The ion beam 18 from ion source 12, which may be a duoplasmatron, surface ionization or electron bombardment source, passes through extractor and focusing electrodes 14, 16 into mass separator 22 and the selected, emergent and slightly divergent ion beam 24 passes decelerating electrodes 26 before encountering the filter 28. In some arrangements, Fig. 2 (not shown), the ion beam may be passed through two separate apertured filters, which may be made, for example, of tungsten or molybdenum. The narrow ion beam 32 is accelerated by electrode 34 and passes through the orthogonal deflecting plates 36, 36 which permit scan or spot implantation of ions, such as boron or phosphorus, in the target 20 which may be a silicon wafer or wafers arranged as an array or integrated circuit. To deliver a useful current of 10<SP>-9</SP> amp. at the target for a spot size of 1 micron the source current density should exceed 2 m.amp./cm.<SP>2</SP> of the desired dopant ion.

Abstract: 1320867 Jointing electrical connections by stamping BUNKER RAMO CORP 15 Oct 1971 [8 Feb 1971] 48161/71 Heading B3A and B3Q Apparatus for crimping electrical contacts (12), Fig. 2 (not shown), to wires comprises means 20 for supplying the contacts singly to a device 22 for correctly orientating them before they are dropped into a tube 26 which is connected at its lower end to means 28, Fig. 10, for delivering the contacts to the crimping means 31. The apparatus includes a base 40 on which a platform 43 is supported by lugs 41. The platform 43 supports a bowl 20 and a vibrator 49 for shaking contacts along a track 52, 78, Fig. 3, and into a recess 76 in a transfer plate 65 which is mounted on a pivot 67 on an inclined platform 61. A pneumatic or electric single or double-acting actuator 74 turns the plate 65 and transfers the contact to a channel 81 down which it slides, assisted by slight vibration of the platform 61 transmitted, through brackets 54, 56, from the lower platform 43. The depth of the channel 81 reduces so that the contact moves upwardly into a second  transfer slot 83 in the plate 65. Return move-  ment of the plate rolls the contact along an upwardly inclined surface 85 and into an opening 87 on the platform. The opening has narrow ends, Fig. 5 (not shown), so whichever way round the contact rolls into the slot, the wider, sleeve-end of the contact is uppermost as the contact falls through the slot into a funnel (97), Fig. 8 (not shown), connected to the tube 26. At its lower end the tube 26 enters a yoke 109, Fig. 10 with a passage 112 through which the contact falls into a feed tube 103. An actuator 116 pushes the contact into the crimping device 31 where it is gripped by a rubber ring 139, Fig. 12, at the exit end of the device. The actuator has an end socket 105, Fig. 15, and a retaining spring 122 for engaging the contact. A guide funnel 35 for wire to be inserted in the contact is adjacent the ring 139.  The crimping device is operated, through a  lever 37, by a cylinder 38, and the apparatus is started by a foot-switch. A selection knob enables travel of the dies to be adjusted for different contacts. Some parts of the feeding arrangement may be formed of a transparent plastics so that progress of the contacts may be observed.

Title: Sensing arrangement for character recognition apparatus
IPC: G06V30/10
Filed: 1968-11-01
Abstract: 1,248,465. Character recognition. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 Nov., 1968 [2 Nov., 1967], No. 51837/68. Heading G4R. Sensing of a character for recognition is performed at the centres of its vertical lines, a matrix store being available which can store the scanned elements of the character and is adapted to store intermediately the information of the first vertical line by using additional sensing points more closely spaced during this line region, successive line centres being taken at preset equal intervals from the centre of the first vertical line. Each column of a matrix store, on receiving a shift pulse, is set with the contents of the preceding column, except in the case of the first column which is set with signals from a multiline horizontal sweep across the character. A first binary counter counts clock pulses at a given frequency between the leading and trailing edges of the first vertical line of the character, and at twice this frequency thereafter. Each clock pulse is also applied as a shift pulse to each column of the matrix from the leading edge of the first line until a second binary counter reaches S, the number of columns of the matrix. The second counter was set with half the count in the first counter (obtained by ignoring the lowest order of the first counter in the setting) at the trailing edge of the first line, thereby specifying the matrix column holding the centre of the first line, and is then incremented by each clock pulse until a count of S is reached as stated. At this point the signals from the centre of the first line are in the last matrix column. Thereafter a shift pulse is applied to every matrix column except the last, every time the first counter passes through zero, thus sampling the character at positions which in fact correspond to the centres of vertical character line positions, the clock pulse frequency being controlled in accordance with the rate of reading to achieve this. The second counter can be dispensed with by using the first counter as above to identify the column holding the centre of the first line, erasing all other columns of the matrix, then shifting the matrix until data appears in the last column. Other modifications for achieving the same end result are described, utilizing ring shift and change of the shift pulse frequency at different times than above.
