Patent GB-1125766-A (GB)
Title: Soil treatment
Inventor: MORRIS RAYMOND JOHN THOMAS
IPC: C08L95/00
Filed: 1964-09-29
Abstract: 1,125,766. Consolidating soil. DUNLOP CO. Ltd. 28 Dec., 1965 [29 Sept., 1964], No. 39526/64. Heading E1F. Soil is treated with a composition comprising a latex or other aqueous dispersion of an elastomeric material blended with an aqueous dispersion of bitumen, the blend containing the elastomeric material in an amount of 1-50 per cent by weight of the total content of elastomeric material and bitumen on a dry basis, and said composition having a total solids content of 1-60 per cent. Suitable elastomers are natural rubber and butadiene styrene copolymer. The elastomers may contain softeners or extenders and the compositions may include plant nutrients, herbicides, pesticides, and selective weedkillers. In the examples the compositions also contain casein, karaya gum, ammonium polyacrylate and hydroxyethyl cellulose as protective colloids and sodium pentachiorphenate, potassium nitrate and ammonium sulphate.

Title: Error detection and correction circuits
IPC: G11B20/14
Filed: 1964-09-29
Abstract: 1,031,829. Digital data storage. SPERRY RAND CORPORATION. Sept. 29, 1964 [Sept. 30, 1963], No. 39637/64. Heading G4C. A circuit for recovering data stored in phasemodulation form in which significant and non- significant output pulses are produced, includes means providing an error signal on the occurrence of two consecutive non-significant pulses. In Fig. 1 (not shown), the output of a detector circuit 10 comprises significant pulse signals representing " 1 "s together with a non-significant pulse occurring between each two successive " 0 "s, the output of a detector 12 being similar with " 0 "s and " 1 "s interchanged. Delay flops 14, 16 are normally effective to inhibit the passage of non-significant pulse signals, but if, due for example to variations in the speed of the recording medium, the timing of the reproduced signals varies, a non-significant pulse may be erroneously gated to one of the outputs 36, 38. This is detected by a circuit including a flip-flop 34 and AND gate 41, the gate being opened in response to the detection of two consecutive non-significant pulses, thereby providing an ERROR-indicating output and, by providing a pulse on a lead O, switching over a flip-flop 20 so that subsequent pulses are correctly treated as being significant or non-significant as the case may be.
Patent GB-1479776-A (GB)
Title: Time recorder
IPC: G01D9/36
Filed: 1974-09-11
Abstract: 1479776 Time recorders SIMPLEX TIME RECORDER CO 11 Sept 1974 [11 Sept 1973] 39651/74 Heading G4T [Also in Division B6D] A time recorder for recording time data in columns by means of a time controlled printing device on a data medium, more particularly a stamp recording card, the printing device and data medium being slidable relative to each other and every recorded time having a specific mark at a given position with a device having scanning means for the data medium to prevent overprinting of time data, wherein the scanning means which is fixed in relation to the printing device is an optical tracing device which is orientated to the position of the defined mark and responds to the presence of the said mark and drives a stop abutment electromagnetically. A card 32 is slid between guide rails 28 and 30 to engage card suuport 38 on slide 36. Electromagnet 58 is positioned on the slide and has a core 60 and functions as a bolt. Actuation of the electromagnet, described below, causes the bolt to engage a flank 48b of teeth 48 on rack 46. The rack is thus entrained to move with the slide and actuates a switch 56 that initiates printing on the card. Time data recorded on a card has the hour of the recorded clock time in the form 00 to 23. The numerals 0, 1 and 2 used in the first digit of the hour recording have a cross-bar at the bottom, more particularly with hour recording in OCR-A characters. There is a printing head 62 and a tracer head 64. Activation of a printing magnet 92 causes printing head 62 to press against rubber strip 80 through inking ribbon 82 and card 32. The tracing head 64 is part of an optical tracing device comprising a light source 66, a photo transistor 68 and an optical glass fibre system 70. The end face 72 of the strand of the system 70 terminates in tracing head 64 and has the dimensions of the crossbars (aforementioned) which are to be traced and is positioned opposite the vertical slip of the column in which the first digit of the hour recording is situated. The transfer head is movable transversly of the card with the printing head but is not connected thereto. The slide 36 is biased to its top position by spring 42 and cord 40. In operation a card is inserted and engages slide 36. As the card moves downwardly the tracing head scans it until it detects a previously printed number. This triggers activation of electromagnet 58 to entrain rack 46 which in turn operates switch 56 and causes a printing operation. The printing head is positioned downstream of the tracing head so that it prints on the line below the line detected.

Abstract: 1381035 Automatic control of current WESTINGHOUSE ELECTRIC CORP 25 Aug 1972 [10 Sept 1971] 39783/72 Heading G3R [Also in Division H2] An intrinsically safe circuit 16 connected between a source of supply 10 and a load 14 includes current limiting devices 44, 50 to prevent excess current being supplied to the load which may be located in a hazardous area. The device 44 comprises a Darlington pair 62, the baseemitter voltage of each transistor 64, 66 of which is matched with the voltage drop across respective diodes 78 so that the current through a resistor 74 is limited to the value at which the voltage drop across the resistor equals that across a diode 80. The current limiting device 50 operates similarly but comprises a single transistor 60.

Title: Process for the manufacture of filaments and films of amide copolymers
Inventor: REEDER FRANK
IPC: C08F20/58
Filed: 1962-10-22
Abstract: A process for producing filaments or films of amide copolymers comprises copolymerizing a vinyl compound and an ethylenically unsaturated carboxylic acid amide bearing a substituent -CH2OR on the amide nitrogen atom, R being hydrogen, alkylol or polyoxyalkylene, in water to form a solution of a copolymer containing at least 50 mole per cent of units of the amide, and extruding the solution and reducing the water content of the extruding stream to form solid filaments, or casting a film from the solution.  Vinyl compounds specified are acrylonitrile, vinyl acetate, methyl acrylate and styrene.  The amide may be derived from acrylic acid, methacrylic acid or itaconic acid. Polymerization may be initiated with a redox catalyst, e.g. ammonium persulphate/sodium thiosulphate.  In forming filaments, the aqueous copolymer solution may be extruded into a coagulant, e.g. an aqueous solution of a salt, such as sodium sulphate, or a water-miscible organic liquid such as methanol or ethanol.  The filaments or films can be insolubilized by heating in the presence of an acidic or acidic-forming substance, e.g. ammonium chloride. Acrylonitrile/N - methylolacrylamide copolymers are illustrated in the examples.

Filed: 1973-08-24
Abstract: 1392682 Cleaning floor coverings J H CREMERS 24 Aug 1973 [25 Aug 1972] 40173/73 Heading A4F In a process for cleaning textile floor coverings, washing liquid is sprayed at pressure in the range 30-35 atmospheres above atmospheric pressure onto the covering to be immediately removed by suction. The partially dried covering may then be completely dried by the application of warm air. Non-dissolvable dirt may be treated by a detergent chemical prior to spraying. Clean liquid e.g. water is forced from a tank 20 by a double acting pump within housing 15 to nozzle 29 which is spaced from the covering 10 via pressure hose 23 which is clipped to suction hose 26 leading to tank 16. The suction nozzle 28 abuts the covering, the nozzles 28, 29 being moved, in use, in direction 31. In a modification, an array of spaced nozzles are employed, each nozzle resulting in a fan shaped spray which is inclined at a slight angle to the longitudinal axis of the array. The washing liquid temperature may be cold or raised to 60‹C.

Movement of members 32, 32', is then stopped and reversed by operation of limit switches engaged by actuator element 48 to effect reverse running and braking by unit 38 to restore the apparatus to the position shown whereat the yardage counter 23 is automatically reset.
