Abstract: 1463317 Laminated electric heater S HORIKI 20 Dec 1973 [20 Dec 1972 26 Dec 1972 15 April 1973] 59216/73 Heading B5N [Also in Divisions B2 C1 and H3-H5] A heating element comprises a substrate 11, an electrically conducting layer 12 and an electrically insulating protective layer 13, the conducting layer being made by mixing a glass powder a metal powder and a binder composed of an organic solvent and a polymer, and firing to decompose the binder and to partially oxidize the metal, the metal being present at between 20 and 97% of the conductive layer and selected from copper, silver, gold, zinc, cadmium, aluminium, indium, thallium, tin, lead, antimony and bismuth. The polymer is natural or synthetic and a list of polymers and classes of polymers is given in claim 1. Because oxidation of the metal is desired, no protective atmosphere is provided during firing. The protective layer may be applied after firing in which case it may be a polymer of the same type as selected for the binder in making the conductive layer, or heat resistant plastics such as melamine resins urea resins benzoguanamine resins fluorinated polyethylenes, silicone resins aminoplast resins, polyimide resins, epoxide resins or polydiphenyl ether resins. The protective layer may alternatively be of inorganic materials such as glass, gypsum, ceramics, calcium carbonate, as boards, foamed if required, adhered to the electrically conducting layer. If the protective coating is applied before firing it may consist of glass. The substrate may be an enamelled metal, ceramic, glass, brick, pottery material, gypsum, calcium carbonate calcium silicate or asbestos formed as a sheet, dish tube or cup. Knitted, woven or non-woven inorganic fibres (glass or ceramic) may be used. The glass may have a silica or phosphate or borate basis with alkali metal or alkaline earth metal, e.g. lead or zinc. Firing takes about 1 hour in air at 600-1000‹ C. The conductive layer may be spread on the substrate, silk screen printed or applied by means of a transfer sheet to which the resistor is attached by a water soluble adhesive which is subsequently dissolved away. It may be attached by means of a pressure sensitive or heat sensitive adhesive. The heating conductor may be a single sheet between electrodes 14 (Fig. 2, not shown) or the sheet may be divided, as shown in Fig. 3 into parallel conductive strips 12.

Filed: 1970-12-17
Abstract: 1334388 Treating I. C. engine charge; purifying exhaust gases SUN OIL CO 17 Dec 1970 [29 Jan 1970] 59898/70 Heading F1B To reduce the emission of oxides of nitrogen from a motor vehicle engine the mixture produced by the fuel supply system, e.g. a four-barrel carburetter 7, is, during off-idle and low-flow main metering operating conditions, enriched as compared with the mixture which would be produced by a carburetter set to the manufacturer's recommended settings for the conditions. Above a predetermined engine or vehicle speed, e.g. 35 m.p.h., additional air is fed to the engine intake. The exhaust gases from the engine are acted on to convert at least part of the CO and HC therein to harmless substances, e.g. by flow through afterburning reactors 4, 4'. The additional air is fed into a carburetter bore 7 through a port 10 or ports upstream of the throttle valve 8 or to the bore of a plate immediately downstream of the carburetter. The air inlet pipe 11 contains a valve 12 closed by a solenoid 19 and a calibrated restriction 13 or an adjustable needle valve. The solenoid 19 is deenergized and the valve 12 opened when the normally-closed switch 18 is opened by a signal from the electrical tachometer-type unit 15. The signal operating the relay 17 may be supplied by the unit 15 when the number of ignition pulses received corresponds to the predetermined engine speed or the number of pulses supplied by a device associated with the vehicle transmission corresponds to the predetermined vehicle speed. The solenoid 19 may be controlled by a mechanically-operated switch responsive to automatic transmission pressure or r.p.m. Air may be fed to the exhaust gases immediately downstream of each engine exhaust valve by an engine-driven pump.

Abstract: 1417696 Non-woven fabrics LANTOR LTD and AUTOMOTIVE PRODUCTS LTD 22 Dec 1972 [23 Dec 1971] 60004/71 Heading D1R A non-woven web usable as a filter medium at temperatures in excess of 200‹C comprises a web of poly-(m-phenyleneisophthalamide) fibres preliminarily bonded by chemical and/or physical means and then further bonded by a resin condensation product of an aralkyl ether and phenol. The web may be corded, garnetted, or air-laid and. the fibres may be cross-linked, randomly laid or parallel laid. Preliminary mechanical bonding may comprise needling or stitching with or without yarn. Preliminary chemical bonding may use 12-20% by wt. of a natural rubber latex, a styrene-butadiene rubber latex or vinyl acetatevinyl acrylate copolymer. Excess binder may be removed by squeezing rollers or suction and the web dried. Drying on one side only displaces binder producing a binder gradient. The fabric may then be pressed. The fabric is then passed through a solution of the resin then either through nip rollers and along a horizontal lattice support with hot air directed on the top surface so as to produce a resin gradient, or passed up a vertical drying tower so that the resin migrates to both surfaces. The resin is preferably cured at a high enough temperature to decompose and remove any preliminary binder and thus produce a filter in which the porosity varies through the thickness. The resin may comprise 20% by weight of the fibres.

Title: Crt display editing circuit
IPC: G09G1/06
Filed: 1968-12-23
Abstract: 1,211,420. Cathode-ray tube display. SPERRY RAND CORP. 23 Dec., 1968 [26 Dec., 1967], No. 60973/68. Addition to 1,108,401. Heading H4T. In a cathode-ray tube display arrangement in which Alpha-Numeric characters are displayed in lines and columns means are provided for selecting an array of characters having predetermined line and column boundaries and for shifting predetermined lines of characters in the array upwardly or downwardly by one or more line positions. The invention is described in term of a modification of the cathode-ray tube display arrangement disclosed in parent Speci fication in which an electronically generated cursor is positioned over a single character to be deleted or at a position in which a character is to be inserted the arrangement operating to "close the gap" when a character is deleted or to make a space when a character is to be insertee by suitably shifting the position of all characters following such deletion or insertion. As shown in Fig. 4a, the operator selects the array (window) by positioning the cursor, firstly over the character (in this case the letter b) at the intersection of the last line 6 and the last column 5 of the array the address of which is stored and then positions the cursor over the character, (in this case the letter z) at the intersection of the first line 3 and the first column 1 the address of which is also available. The arrangement then operates to remove the data representing the letter z from the main memory of the system (which stores data representative of all characters in addressable location corresponding to the locations on the CRT screen) and to store "zeroes" at such location to produce a blank at the corresponding location on the CRT screen. The removed data which, initially, is temporarily stored in a first register (register CR of parent Specification), is now transferred to a second register (register ZR of the above noted Specification) and the data in the memory at the location corresponding to the character H is read into register CR. The data representative of the character z is now read out of register ZR and replaced in the memory at the location which previously held the data corresponding to the character H so that the character z is shifted down by one line position and is now displayed at the intersection of column 1 and line 4. This mode of operation is now repeated for the characters H and P which are shifted downwardly to lines 5 and 6 respectively the data representative of the character X being deleted from the memory and similarly for column 2 to 5 (with the deletion of the characters in line 6) so that line 3 is blank (Fig. 4b) and a new line of characters may then be inserted. For line deletion the operation is similar except that the steps described above commence at the last line in the array (window) and each line is moved upwardly when the top line has been deleted. Block circuit diagrams of the logic circuitry and flow diagrams of the sequence of operations are given.

Patent GB-710798-A (GB)
Abstract: 710,798. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Jan. 27, 1953'[Feb. 9, 1952], No. 3457/52. Class 40 (4) An incoming V.F. relay set determines whether or not through V.F. signalling may be used by testing for the absence or presence of battery on the outgoing speech loop. When relay X, in the voice-frequency receiving equipment VFR, operates at the beginning of a short seizing pulse it brings up E and EA. At the end of the pulse release of X brings up high speed relays A, AA, AB, AD. Relays AB, AD, switch through the speaking leads and remove the line terminations YA, YB. AA brings up BG. When X reoperates to the first digital impulse, relays AB, AD fall back and to effect line-splitting and remain disconnected by the dialling relay C for the rest of the train. Relay A repeats the impulses over the forward loop to set the selector GS in known manner. If the selector is set to a local outlet or a trunk using d.c. impulsing, battery and earth is present on the + and - wires and brings up relay I when C releases. Subsequent digits received by relay X are repeated by A to the outgoing loop as d.c. impulses. When however GS switches through to a V.F. trunk, no battery is present in the outgoing loop and I fails to operate so that TC comes up when C releases. TC holds A, AB, AD operated and removes the attenuation pad PA. In the outgoing relay set, 1TC operates over the P-wire and brings up ET. Further V.F. signals may now pass straight through the connection. On release a long X pulse releases EA (by means not shown) which is followed by E. AA operates C. When X falls back TC, BG, A, AB. AD, and AA release. AA releases C during whose release time a release guard signal is reverted in known manner. An operator may have access to the V.F. trunk over jack OJ, sleeve relay S bringing up ET to busy the trunk to the selector GS.

Title: System for generating line drawing of a scanned picture
IPC: G06K17/00
Filed: 1978-07-07
Abstract: A digital system detects edges in a full tone picture by scanning and reproduces them in solid lines of controllable width to provide an outline drawing of the picture. Each line of video information produced by scanning the picture is digitised by an A-D converter. Each digital sample is compared to a digital sample delayed by a predetermined amount to generate a difference signal which is indicative of a change in the gray scale in a direction perpendicular to the scanned lines. The digitised samples of the video signal are stored in shift registers having capacity sufficient to store data representing a plurality of scan lines. Selected digital samples from the stored data are compared to samples of the line being scanned to detect changes in the gray scale in a direction parallel to the scanned lines. These detected changes in the gray scale are combined to generate a signal which operates a printer to generate a line drawing of the scanned picture.
