Patent GB-480914-A (GB)
Title: Improvements in and relating to the preparation of bleaching and sterilising agents
IPC: C01B21/09
Filed: 1937-02-23
Abstract: Bleaching and sterilizing agents consisting essentially of chloramines are obtained by reacting nitrogen trichloride or products containing nitrogen trichloride with ammonia in the dissolved or gaseous state.  The ammonia may be wholly or partially replaced by urea.  According to an example, an aqueous solution containing ammonium chloride, common salt and hydrochloric acid is electrolyzed, carbon rods being employed as electrodes.  During electrolysis, air is blown into the vessel, the resulting gases containing nitrogen trichloride being conducted into a dilute solution of ammonia.  In the milling of grain, gases coming from a source of nitrogen trichloride are directed into two pipes, one proceeding direct to the mill in order to treat the flour with nitrogen trichloride and the other being conducted to a vessel filled with a dilute solution of ammonia, so that the resulting solution may be used for treatment of the water used in washing the wheat.  Specification 468,684, [Group I], is referred to.ALSO:Bleaching and sterilizing agents consisting essentially of chloramines are obtained by reacting nitrogen trichloride or products containing nitrogen trichloride with ammonia in the dissolved or gaseous state.

Title: Improvements in or relating to radio signalling systems particularly for radio beacons
IPC: G01S1/02
Filed: 1945-03-05
Abstract: 604,920. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. March 5, 1945, No. 5512. Convention date, June 12, 1943. [Class 40 (vii)] In a system supplying energy carrying two types of modulation, such as course-identifying signals and voice signals, to a common load in a predetermined phase relationship, this relationship is maintained despite changes in the circuit characteristics of the carrier source by loosely coupling the carrier output, at a point in advance of the modulator for the first type of signal, to an electronic modulator for the second type of signal, this latter modulator operating substantially at saturation so that any of the first modulation which may be present in the carrier at this point will be substantially eliminated. The invention is described with reference to a four-course beacon. system similar to that described in Specification 603,568 in which aerials 1, 2, 3 provide a two-tone overlapping-beam system with the carrier from the source 15 mechanically modulated in lines 26, 27 and aerials 7, 2, 9 provide a keyed overlapping-beam system controlled by a change-over relay 61. Bridge 28 with a cross-over in one arm supplies the tonemodulated side-bands to aerials 1, 3 in antiphase, the carrier being suppressed, and also supplies carrier and side-bands through bridge 40 to aerial 2. Carrier-frequency from the source 15, which at point 21 will contain some tone-frequency modulation from modulators 24, 25, is fed through a loose coupling 16 to a pair of balanced thermionic modulators 52, 53 which are biassed so that the energy supplied will drive them to saturation. Voice frequency from source 51 is supplied to both modulators and 1020-cycle tone frequency from source 50 to modulator 52 only, anode modulation being used in each case. The outputs of modulators 52, 53 are supplied through a bridge 57 so connected that only the tone-frequency sidebands pass over circuit 58 to aerials 7, 9, whilst the tone-frequency and voice-signal side-bands and also the carrier pass through bridge 40 to aerial 2. Specification 538,036 also is referred to.

Abstract: 907,599. Knitting. M.K.M. KNITTING MILLS Inc. Feb. 15, 1961, No. 5703/61. Class 74 (2). A panel, for a woman's garment, having selvedges which are vertical when worn, has two breast cups in the lower and upper portions of which the wales respectively diverge and converge with respect to the vertical centre line of the cup. The panel is shaped by four sets of narrowing fingers 10, 12, 14, 16 with narrowing points 20 each directly above a needle 22 which shift the loops one needle along. The fingers are operated by buttons on a pattern chain and movement of the fingers is limited so that bands 40, 42, 44 are not touched and are knitted continuously. The operation of the a button on the pattern chain alone causes the fingers 10 and 12 to drift inwardly one needle space. Operating with buttons a, c and f fingers 10 and 12 move outwards after dipping. Button f alone causes fingers 10 and 12 to shift inwards during the knitting of a course and without transferring loops. When knitting the breast cup area, commencing at A and A<SP>1</SP> and forming new wales to the left and right of bands 40, 42 by means of the a, c, f buttons. On completion of this part of the swim suit and most of a plain part up to C, D, C<SP>1</SP>, D<SP>1</SP> a button b stops the machine for inspection. When a, d and e<SP>1</SP> buttons operate together fingers 10, 12 and fingers 14, 16 move, respectively, inwardly and outwardly one space whereas buttons e<SP>1</SP> and f individually shift the fingers 10, 12 and 14, 16 outwardly and inwardly one space. This pattern is suitable for nylon-covered rubber yam. Alternatively, a bulkier yarn, e.g. five ends of a blend of crimped and uncrimped nylon filaments may be employed e.g. in a pattern such as shown in Fig. 5.
