Abstract: 1,032,248. Character recognition. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 13, 1964 [Dec. 19, 1963], No. 46263/64. Heading G4R. A function 42 (Fig. 6, not shown), is detected 44 by a matrix of photo-cells connected to a vector generating unit 46 which generates signals corresponding to vectors extending from each of the function occupied zones to selected unoccupied zones. In a first embodiment the vectors extend in four orthogonal directions into every adjacent unoccupied zone. In a second embodiment the vectors may extend in any of eight directions to unoccupied zones having those adjacent zones nearest the occupied zone also unoccupied. The vectors are represented by potentials on different lines corresponding to the direction and obtained by comparision of the states of adjacent photocells (Figs. 8 and 12, not shown), generating potentials through transistors (Figs. 7 and 11, not shown). All the potentials in a common direction may be summed 100 to give the total potentials in each direction and these may be compared 102 in pairs to determine the one of greater magnitude (Fig. 15, not shown).

Abstract: 1490561 Control of printers CENTRONICS DATA COMPUTER CORP 29 Oct 1974 [12 Nov 1973] 46650/74 Heading G4H A dot matrix printer comprising two print heads for simultaneously printing respective halves of a line of print, successive lines being printed in alternate directions, is controlled by the following sequence of operations: (a) loading binary signal groups representing characters into a recirculating register, (b) shifting the groups until the one representing the first character to be printed by the right hand print head is shifted into the output stage of the register, (c) temporarily storing that group, (d) shifting again until the group representing the first character to be printed by the left hand print head is in the output stage, (e) converting the stored group into dot matrix form and storing the converted signal, (f) converting the group in the output stage into dot matrix form, and (g) simultaneously applying the dot signals for both characters to their respective print heads for printing. Each pair of dot matrix characters is transmitted column by column, corresponding columns of the two characters being printed simultaneously. The above process is then repeated for the next character for each print head and so on for the whole line, at the end of which a new line of characters is stored in the recirculating memory and accessed in the reverse order as printing now takes place from right to left. The third line is treated in the same way as the first, and so on. Each character may be printed in 'expanded form' when each dot column is printed a plurality of times (this feature is claimed in Specification 1,490,562. Circuitry for affecting the above and other operations (e.g. line feed) is described in detail with reference to Figs 2-6 (not shown).

Abstract: 1518566 Seals CRANE PACKING CO 9 Nov 1976 [2 Jan 1976] 46680/76 Heading F2B A rotary end face seal comprises relatively rotatable seal rings 14, 17 having radially contacting sealing surfaces 16, 29 respectively, the ring 17 being located and held against rotation relative to a gland plate 19 and being axially supported in the gland plate 19 with limited contact via a land 33 located at the radially outer region of the ring 17, the design of the seal rings 14, 17 being such that the centroid 31 of an axial section through the ring 17 is located radially inward of the land 33 so that sealing pressures on the contacting surfaces 16, 21 provide a clockwise turning moment about centroid 31 as shown, whilst the centroid 30 of an axial section through the ring 14 is located such that fluid pressures on selected portions of the ring will develop counterclockwise turning moments of force about the centroid of the ring 14. The arrangement is such that the combined effect of each ring 14, 17 tending to twist about its centroid 31, 30 will pinch off face leakage at the outer diameter of the sealing faces 16, 29 and also counteract distortion of the faces 16, 29 caused by pressure and temperature gradients across the surfaces thereof whereby the necessary sealing flatness of the faces 16, 29 is preserved. To achieve the above results, two further conditions are also required. (1) The ratio of the radial sealing faces width to the inner radius of the faces must be in the range of 0À085 to 0À30, and (2) hydro-pads, in the form of lubricant recesses 28, must be provided, and as shown are arranged around the periphery of the seal face 16.

Title: Apparatus for blocking the dialling operation of a subscriber telephone set
IPC: H04M1/677
Filed: 1972-10-16
Abstract: 1371120 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 16 Oct 1972 [17 Dec 1971] 47540/72 Heading H4K A substation includes a logic circuit which in the event of a prohibited first digit, e.g. "0" or "9" being dialled or of dialling being attempted before the arrival of dial tone or of a short pulse being dialled, causes further impulse transmission to be inhibited. The short pulse of typically less than 35 msec. duration would not be recognized by exchange equipment but could trigger the local digit counter into believing that a permitted first digit has been dialled thereby permitting an unauthorized code to be subsequently transmitted. Short pulses also occur if the user dials a digit 10-N and then actuates his switchhook N times in an attempt to dial "0". The exchange would probably recognize the digit "0" even though the "N" portion thereof comprises relatively short makes and breaks. If the logic responds to any of the above eventualities it operates a bi-stable circuit which causes a locally generated busy tone to be injected into the subset circuit and connects a low impedance chain across the live wires during impulsing. A busy tone detector includes a guard circuit responsive to a speech or noise frequency, e.g. 1600 Hz so as to enable the subset to dispense with the handset shortcircuiting arrangement disclosed in Specification 1,360,038. Impulses applied to line by the subset dial are squared and integrated (thereby eliminating impulses of less than 8 ms.) before being applied to the logic circuit. Impulse transmission is prevented if the subscriber simulates a so-called "users-tone" by juggling his hook switch (this in effect clears the exchange register first seized but does not clear the logic circuit's impression that a permissible first digit has been dialled). At the substation the temporary break in the current supply as a new register is switched into the connection is recognized by the logic so as to inhibit further transmission. On the other hand, the failure of current supply which sometimes occurs after a full dialling sequence is not effective to trigger the logic into turning on the local busy tone.

Abstract: 1359780 Semi-conductor device SIEMENS AG 16 Oct 1972 [28 Oct 1971] 47569/72 Heading H1K A semi-conductor device is manufactured as follows: an epitaxial layer 2 is deposited on a substrate 1, e.g. an N-type gallium arsenide, the layer 2 being of the same conductivity type but greater resistivity than the substrate; an opening is made through the layer 2 into the substrate and ohmic contact 4 made thereto, the contact being of a gold-germanium alloy or a silver-indium alloy; a Schottky contact 5 is made to the layer 2, the contact being of chromium; metal seed layers 6 are applied to contacts 4 and 5, layers 6 being of silver, gold or nickel; an insulating layer 7, e.g. of a baked photosensitive varnish, SiO 2 , Al 2 O 3 , or Si 3 N 4  is formed over the device, and holes 8, 9 are opened to the seed layers; subsequently conductive tracks 10, again of gold, silver or nickel, are deposited on the layer 7 to the holes, and the device electrolytically treated in order to fill the holes 8 and 9 with conductive material 14 of the seed layer, and subsequently when contact is established with the tracks 10 these are also built up to form beam leads; finally an insulation layer 12 is used to protect the surface while the device is etched in an H 2 SO 4 , H 2 O 2  and water solution to produce the unsupported beam leads which are suitable for direct connection in a circuit. The thickness of the insulating layer 7 reduces capacitance between the leads 10 and the layer 2, without causing steps in the conductive track due to infilling with material 14. Material 14 is not deposited on tracks 10 until the tracks make electrical contact with the filling material 14 since the tracks are electrically isolated on the layer 7.
