Title: Circuit arrangements for use in data display devices
IPC: G06F3/153
Filed: 1976-09-24
Abstract: 1529098 Cathode-ray tube display data processing SIEMENS AG 24 Sept 1976 [25 Sept 1975] 39645/76 Heading H4T A circuit for use in a data display device to supply data store addresses of data words, e.g. DZ1, DF1, DZ2, ... DZ5 assigned to representable characters Z1, Z2, ... Z5 and to "field control" characters e.g. DF1, DF2, DF3, comprises an address register BAR for storing an address word BA which represents the position of a representable character Z the data word of which, or of a field control character F pertaining thereto, is to be addressed, a second address register DAR for storing a second address word DA representing the address of the data word which is to be addressed relative to that of the corresponding representable character, an address counter A which emits a data store address AD and whose count increases by 1 after each read-out, a counter ZZ which counts read-out of data words assigned to representable characters, and means including a subtractor SUB for modifying the count of address counter A by the address DA stored in the register DAR in the event of identity, established by a comparator VG, of the address word BA and the count of the character counter ZZ, thereby to form the address of the data word to be addressed. As shown, field-control character F1 pertains to, and determines the nature of, representable characters Z2, Z3, and F2, F3 pertain to Z4, Z5 etc. The addresses A0 . . . A7 of characters F and Z are stored in the same data store. If Z4 is to be addressed, BA=4 and DA=0. Switch SS2 issues, upon each read-out, a signal LE to the data store which returns SZ = 1 when the address is that of a control character F and SZ = 0 when the address is that of a representable character Z. Decoder DC issues a 1 for each character Z and these are counted in ZZ. When the count of ZZ is 4, VG issues S8 = 1 (no signal otherwise) and subtractor SUB subtracts DA = 0 from the count corresponding to A6. If DF2 is to be addressed, BA = 4 and DA = 2. Thus, DA = 2 is subtracted from the address A6, so that an address A4 is issued to the store by the address counter A.

Title: Ultrafine boron nitride and process of making same
IPC: C01B21/06
Filed: 1968-08-22
Abstract: 1,241,206. Boron nitride. A. P. GREEN REFRACTORIES CO. 22 Aug., 1968 [5 Sept., 1967], No. 40295/68. Heading C1A. [Also in Divisions B3 and C5] A boron nitride consists of particles composed of primary crystallites having stacked graphite type lamellµ with the layers arranged at random with respect to each other, the average crystallite thickness on the " C " direction perpendicular to the layers being 14 to 25 A and the " C " spacing (for the 002 planes) being 3.36 to 3À64 A. The crystallites may be 45 to 100 A broad. The particles may be equiaxed and less than 1000 A, and may be partly present as agglomerates. The boron nitride which may contain boron oxide as impurity is greater than 50% pure, preferably above 90% pure and has a bulk density of 0.015 to 0.031 g/ml. A product of substantially 100% purity and composed of platelets several microns broad and 1000 A thick may be formed by nitriding the boron nitride with ammonia. The boron nitride is prepared by introducing an inert gas into a bed 12 of a porous medium, introducing boric oxide, orthoboric acid, metaboric pyroboric acid, condensed boric acid or mixtures thereof into the bed which is maintained at 1500‹ C. to 2400‹ C. to produce boric oxide vapour and reacting the boric oxide vapour in an adjoining reaction zone 10 at 600‹ C. to 2400‹ C. with anhydrous ammonia. The inert gas may be nitrogen, helium or argon, and the porous medium of the bed may be boron nitride, carbon or graphite, the last two of which become coated with boron nitride under the prevailing reaction conditions. The porous bed may be heated by induction, plasma or electrical resistance heating. Alternatively the bed may be dispensed with and the boron oxide vaporized directly by a plasma jet (Fig. 4, not shown). Vacuum may be applied to the reactor outlet to speed up the gas flow, and the product may be nitrided with further anhydrous ammonia in a further reactor to convert boron oxide impurity into boron nitride.

Abstract: 1,105,382. Metal coated wire. ROEHR PRODUCTS CO. Inc. 2, March, 1965 [2, March, 1964], No. 40339/67. Divided out of 1,105,381. Heading E1K. [Also in Division B3] Work hardened solid or tubular metallic filaments having a maximum diameter of .0005 inches (solid) or .015 inches (tubular) are made by sheathing each of a plurality of elongated elements from which the filaments are to be formed with a material having physical characteristics differing from those of the elements to permit separation of the sheath material from the elements when desired; bundling the sheathed elements in parallel relationship; hot forming the bundle to reduce the cross-section thereof; drawing the elements therein to a preselected filament cross-section; and removing the sheathing material. As described stainless steel wires are sheathed with copper or monel metal, a bundle of the sheathed wires are assembled in a cylindrical housing which is then evacuated and sealed and compacted e.g. by compression or extrusion to form a billet. The billet is then hotformed by extrusion or rolling and is then cold-drawn to the required cross-section. The material of the housing and sheathing is then removed e.g. by immersion in nitric acid. Tubular filaments can be similarly made by providing tubular elements of stainless steel with cores and sheathing of copper or monel metal and repeating the above procedure.

Title: Improvements in and relating to the drawing of metal tubing
Inventor: RICHARDS SAMUEL HUGH
IPC: B21C1/02
Filed: 1963-10-14
Abstract: 1,094,751. Drawing. MARSHALL RICHARDS MACHINE CO. Ltd. Oct. 13, 1964 [Oct. 14, 1963], No. 40371/63. Heading B3P. A method of drawing metal tubing comprises leading a coil of tubing from a rotating paying- out spool through a drawing die, laying the tubing, as it leaves the die, in a helix on the surface of a rotating drawing block and collecting the tubing as it leaves the block on a rotating take-up spool, said take-up spool subsequently serving as the paying-out spool when, in a later operation the tubing is drawn in the opposite direction through a further die. An apparatus for carrying out the method comprises a rotatable drawing block driven in either direction by a motor 3. To the left of the block are spool supporting members 5, 6 and to the right are spool supporting members 7, 8, the members having means for reciprocating the support in a direction parallel to its axis, means for driving a spool thereon in a take-up direction, and a slip clutch to act as partial braking means when the spool is rotating in a paying out direction. The block 1 has a pulling in dog 9 pivotable through more than 180‹ to receive tubing from spools 5 and 6 or 7 and 8. Associated with the block 1 are two die boxes 10 and 11, each movable in a direction parallel to the axis of the block by an hydraulic ram 15. Operation.-The end of a length of tubing is drawn from a swift and after lubricating, inserting a floating plug and pointing is passed through the die in box 10, gripped by the dog 9 and drawn on to the block 1, which is rotated slowly as the die is moved back towards the flange 2 of the block. When a number of turns are on the block the leading end of the tubing is released and is secured to either spool 7 or 8. The take-up spool and block are rotated at speeds which maintain tension in the tubing until the whole length is coiled on the spool 7 or 8. Maximum utilisation of the machine is achieved by drawing alternately from one side to the other, one pair of spools being used for drawing while the other is prepared. The support members are movable to line up with whichever of the dies is being used.

The facing layer 16 and backing sheet 12 are coextensive and secured together by adhesive or heat-sealing. The diapers are formed by feeding compacted wood pulp 41 to a grinding mill 42 where short fibres are formed and blown on to a belt 43, the resultant layer 44 being compacted by rolls 46, 47. Moisture is sprayed on to the web at 48, the web then passing between rolls 49 whereby a paper-like skin 51 is formed on its upper surface. The thickned portions 19 are formed on passage through roll 53 and embossing roll 52 having spaced circumferential projections 54. A cutter 56 divides the web into individual batts 14. Polyethylene film 12 is fed from roll 58 and supplied with adhesive at 59. The facing layer is formed by feeding a supply of short cellulosic fibres 70 and staple fibres 71 to a mixing apparatus 72, comprising two rotating lickerins, which suspends the fibres from each source in separate gas-streams directed towards each other and combining to form a single stream wherein the fibres from each stream cross over one another to form the facing layer. The web 73 passes from apparatus 72 to station 75 where a bonding agent is supplied and is thereafter dried on passing between rollers 76. The web then passes upwardly for bonding with the batts 14 and film 12. Individual diapers are cut off by cutter 62.

Title: Television receivers

Filed: 1972-09-06
Abstract: 1399498 Protective arrangements LOEWE OPTA GmbH 6 Sept 1972 [8 Sept 1971] 41281/72 Heading H2K [Also in Division H3] A horizontal deflection circuit 4 of a television set, supplied from a rectifying unit having a rectifier 1 and a capacitor 3, is protected by a control thyristor 2 connected in series between the rectifier and capacitor and normally triggered by a feedback voltage taken from the anode of a switching thyristor (20,-Fig. 3, not shown) in the deflection circuit such that should a fault occur the resulting drop in the voltage causes the control thyristor to cease conducting. A shunt, e.g. a resistor 9, is connected across the control thyristor so that when the condition causing the fault ceases, or has been removed, the capacitor 3 can charge through the shunt until the increase in voltage at the switching thyristor causes the triggering of the control thyristor. As shown, the anode of the switching thyristor is connected through a diode 5 and a resistor 6 to the firing electrode of the control thyristor 2 and to a capacitor 7 which is charged by the voltage. Fig. 2 illustrates an arrangement in which transistors are used in the firing circuit of the control thyristor. In the normal operational state, ignition current for the control thyristor 2 is derived from the capacitor 7, transistor 12 being turned off and transistor 15 turned on. When a fault occurs and the feedback voltage from switching thyristor 20 falls, capacitor 7 discharges rapidly through resistors 16, 17 and the gate-cathode path of thyristor 2. Consequently transistor 15 is turned off, transistor 12 is rendered conductive through resistor 14 and thyristor 2 is blocked. Also, capacitors 3 and 11 are discharged through resistor 10 and since the current flowing through resistor 13 and the collector-emitter path of transistor 12 is smaller than the firing current of thyristor 20, the latter remains blocked until the fault is removed and capacitors 3, 11 can re-charge through transistor 12 to provide the feedback voltage from thyristor 20.
