Title: Improvements in or relating to the treatment of keratinous fibres
Inventor: HANNAY RAMSAY JOHN
IPC: D06M13/256
Filed: 1961-12-14
Abstract: The setting of keratinous fibres, e.g. wool, mohair, cashmere, marina, angora and camel hair, alone or in admixture with other fibres, e.g. cotton is effected by treating them with an aqueous solution of ethylene sulphite <FORM:0958816/D1-D2/1> or a compound having the formula HO-CnH2nSO3M or HO CnH2nSO2M in which n is 2, 3 or 4 and M is an alkali metal.  The aqueous solution may also contain an anianic wetting agent of the alkyl aryl sulphonate alkyl sulphate type.  If the keratinous fibres are in the form of a garment the garment may be steamed with creases or pleats arranged in the desired places either during or after treatment with the aqueous solution to set the creases or pleats in the fabric.  If the fabric is not in the form of a garment it may be dried after treatment with the aqueous solution and steamed when arranged in creases or pleats at a later stage.  Similarly yarns which have been treated with the aqueous solution may be steamed after conversion into a fabric.  The process may also be applied to the setting of curl in wool yarn.

Title: Current sources
IPC: G05F3/22
Filed: 1971-09-30
Abstract: 1335289 Automatic current regulation WESTERN ELECTRIC CO Inc 30 Sept 1971 [5 Oct 1970] 45488/71 Heading G3X A current source for an integrated circuit includes a pair of low-gain transistors, and at least one high-gain transistor connected so as to couple a control voltage to the bases of the lowgain transistors while preventing the base currents  of the low-gain transistors from disturbing the control voltage. The circuit shown in Fig. 2 forms a positive current source in an NPN majority integrated circuit using PNP transistors 30, 40 with a common emitter connection to a voltage supply VS1. A control voltage is developed across a resistor 26 and is applied to the bases of transistors 30, 40 through high-gain NPN transistors 50, 60. Because of the circuit material, the PNP transistors 30, 40 are low-gain, and their large base currents are diverted to earth through the base-emitter junction of transistor 50 and a resistor 35. A constant current output from transistor 30 is obtained with a magnitude determined by the control voltage across resistor 26, which stabilizes one normal base-emitter voltage below the supply VS1. The resistor 35 may be replaced by a negative constant current source to increase the output range of the circuit Fig. 3 (not shown). In the arrangement of Fig. 4, a negative current source including NPN transistors 10, 20 is connected to share a common control resistor 16 with the positive current source 30, 40 so that the output currents from the two sources will be in a fixed ratio.

Abstract: 1286851 Fuel injection systems PETROL INJECTION Ltd and H E JACKSON 24 June 1970 [27 June 1969 17 Sept 1969] 32531/69 and 45806/69 Heading G1N [Also in Division F1] In an I. C. engine fuel injection control system, opening pulses are applied from a unit 200 to the injectors 83 at an unvarying constant frequency, the duration of the pulses being controlled by the position of an air valve 4, the pressure of the fuel at the injectors also being controlled by the position of valve 4. In one embodiment, Fig. 2 (not shown), the control unit 200 is an astable multivibrator whose pulse duration is determined by a potentiometer 205 as shown in Fig. 1. In an alternative, Figs.4-8 (not shown), the unit 200 is constituted by a sawtooth generator which produces constant frequency pulses and a signal generator producing a D. C. signal whose magnitude is controlled by the position of valve 4, e.g. by varying an inductance, the sawtooth waveform and the D.C. signal being compared to produce an injector opening signal when the sawtooth waveform exceeds the D.C. signal. As shown, the valve 4 is positioned by detecting the pressure between the valves 1 and 4, via conduit 29, to maintain the depression between 1 and 4 constant by positioning valve 4 via a unit 102 and a piston 8A. The position of valve 4 also controls the pressure of the fuel via conduit 43 and control unit 100 which controls an excess fuel control valve 112, 113. Units 100 and 102 are as described in Specification number 1254181. A valve 101A in line 43 may provide fuel enrichment during starting by controlling valves 66A, 66B.

Filed: 1975-11-06
Abstract: 1515720 Automatic exchange systems WESTERN ELECTRIC CO Inc 6 Nov 1975 [7 Nov 1974 (2)] 46015/75 Heading H4K A ring trip arrangement common to a group of lines each of which receives ringing current during a different phase, comprises a loop current detector that is selectively connected to one line at a time during the ringing phase thereof. Preferably all the lines are arranged in groups each with a common loop detector, and a common ringing generator is connected to each detector so as to apply current therethrough to more than one line during each phase (Fig. 1 not shown). The arrangement is for use in a TDM system where high voltage ringing must be applied at the line circuits rather than via the network. Fig. 3 depicts the arrangement for a single group. A not shown control system marks wires BPS, BBS of a called line and at the start of each ringing phase (there being 4 phases, each of 1 sec on 3 secs off) also marks BRBS, BRBC such that flip flop RFF sets to turn-on relay RINGO. The latter connects ringing current from generator RG via common detector D1 to the ring lead R of the called line TS1. At the end of the phase, wires BRBS, BRBC are marked such as to reset RFF and thus drop RINGO. During the "silent" portions of ringing, line relay LCO monitors the line for an answer signal and repeats the answer via gate SS to control (SS is prepared by the called line marking on BPS, BBS and the reset condition of RFF). If the subscriber replies during a ringing phase, detector D1 causes RFF to immediately reset, thus dropping RINGO and thereby permitting LCO to rise with results as before.

Abstract: 1,130,860. Preparation of alkylolated amide copolymers. DE SOTO Inc. 4 Nov., 1965 [9 Nov., 1964], No. 46768/65. Heading C3P. A process for the production of non-gelled, organic solvent-soluble, alkylolated amidecontaining thermosetting copolymers comprises copolymerizing a monoethylenically unsaturated carboxylic acid amide with other ethylenically unsaturated copolymerizable material in solution in an organic solvent in the presence of a basic compound and an aldehyde, so that copolymerization and alkylolation are simultaneously effected, at a temperature of at least 275 F. and at elevated pressure, without removal of any volatile component(s). In a preferred embodiment, the monomers are added incrementally and the organic solvent comprises a mixture of a major proportion of an aromatic hydrocarbon and a minor proportion of a C 1 -C 3  alkanol; when an alcohol is present in the solvent a limited amount of etherification of the alkylol groups occurs. Amide monomers specified are acrylamide, methacrylamide, itaconic acid diamide, maleic acid diamide, fumaric acid diamide, sorbic acid amide and muconic acid diamide, the first three of these being preferred. Suitable comonomers include styrene, vinyl toluene and methyl methacrylate (which form " hard " polymers); C 2 -C 20  alkyl acrylates (which form ''soft" polymers); and, also, vinyl chloride, vinyl stearate, butyl vinyl ether, olefins, acrylonitrile, maleic diesters, conjugated unsaturated fatty acids, and unsaturated polyester resins (see Specification No. 1,012,484). The preferred basic compounds are amines, particularly tertiary amines. Any aldehyde is suitable for alkylolation but is generally one of the type R-CHO where R is a hydrocarbyl group; preferred are formaldehyde and substances which yield formaldehyde, e.g. paraformaldehyde, hexamethylene tetramine or trioxymethylene. In examples (1) a mixture of acrylamide, styrene, ethyl acrylate, methyl methacrylate, methacrylic acid and an unsaturated polyester is copolymerized with a di-t-butyl peroxide-azobisisobutyronitrile-benzoyl peroxide-cumene hydroperoxide catalyst combination and (2) a mixture of acrylamide, styrene, ethyl acrylate and methacrylic acid is copolymerized with an azobisisobutyronitrile-di-t-butyl peroxide catalyst; in both cases alkylolation is effected with paraformaldehyde. The alkylolated polymers are particularly useful in the production of cured coatings.
