Title: Electro-magnetic drain gage
IPC: G01L1/14
Filed: 1949-06-22
Abstract: 659,963. Electric indicating systems. GWATKIN, J. S. (Black & Decker Manufacturing Co.). June 22, 1949, No. 16568. [Class 40 (i)] In an electromagnetic strain gauge (Figs. 1, 2), mounted on a base element subjected to stretching or bending stresses, an arm 2 spaced parallelly to the base and screwed thereto at 3 carries two facing E-shaped electromagnets 5, 6 having coils 10 on the centre limbs and arranged with the long edge of each E extending across the base, which are mounted separately on non-magnetic brackets 7, 8 screwed to the arm 2. An armature 12 moving between the magnet poles is carried by an arm 14 which is screwed to the base member adjacent the free end of the arm 2. Thus bending or stretching the base differentially varies the air-gaps 16, 17 and the inductances of the coils, which are measurable in known manner to indicate the strain variations. All the gauge members may be of material having the same thermal, coefficient of expansion, to minimize errors due to temperature changes.

Title: Improvements in and relating to the manufacture of rubber threads
IPC: C08J5/02
Filed: 1934-09-18
Abstract: Relatively inextensible rubber thread is made by incorporating glue or gelatine with a coagulable rubber dispersion, coagulating the dispersion, and simultaneously with coagulation or later rendering the glue &c. at least in part insoluble in water by treatment with formaldehyde or other insolubilizing agent.  The inextensibility of the thread, or yarn spun or fabric woven or knitted from the thread may be partly removed by treatment with hot water containing dyestuffs, which treatment dissolves out the glue &c. not insolubilized and dyes and vulcanizes the thread. Specifications 441,002, [Group IX], 442,931, 442,935, 442,936, and 443,284, [all in Group V], 447,973; 448,098, [Group V], and 449,314 are referred to.ALSO:Relatively inextensible rubber thread is made by incorporating glue or gelatine, with or without casein, albumen, water-soluble natural and synthetic gums and resins, cellulose esters and ethers, sodium silicate or sugar, with a coagulable rubber dispersion, and simultaneously with coagulation or later rendering the glue &c. at least in part insoluble in water by treatment with formaldehyde or other insolubilizing agent.  The dispersion may be extruded into a bath of liquid coagulant containing the formaldehyde &c.  The inextensibility of the thread, or yarn spun or fabric woven or knitted from the thread may be partly removed by treatment with hot water to dissolve out the glue &c. not insolubilized; this dissolving-out-e.g. with hot water containing dyestuffs-may also vulcanize and dye.  The inextensible thread may be steamed with simultaneous stretching, dried, and then in the stretched inextensible condition woven or knitted with other textile fibres into fabric-e.g. lace-before the partial dissolving-out.  The rubber dispersion may contain also viscose or cellulose, glycerine to prevent the outer surface of the thread becoming brittle when dry and linen, or cotton or artificial silk fibres.  Specifications 441,002, 442,931, 442,935, 442,936, 443,284; 447,973, [Group IV], 448,098, and 449,314 are referred to.

Title: Synergistic mixtures of antioxidants for natural and synthetic rubber
IPC: C08K5/13
Filed: 1957-05-27
Abstract: A synergistic antioxidant composition for natural or synthetic rubber comprises a mixture of an aralkyl monohydric phenol and a tertiary alkyl monohydric phenol wherein the phenol ring of the latter contains at least two tertiary alkyl groups having from 4 to 9 carbon atoms.  Preferably the composition comprises (1) an aralkyl phenol of the formula:  <FORM:0843853/IV(a)/1> wherein R is hydrogen or an alkyl radical having from 1 to 9 carbon atoms, n is 0, 1, or 2 and x is 1, 2, or 3, n being always at least 1 less than the value of x, and (2) a tertiary alkylated phenol of the formula: <FORM:0843853/IV(a)/2> wherein x is 2 or 3, n is 0, 1, 2 or 3, R is a tertiary butyl or tertiary amyl radical, and R1 is a tertiary octyl or tertiary nonyl radical, R and R1 being attached to the benzene ring in any of the 2, 4, and 6 positions.  The aralkyl phenols specified are mono-, di- and tri-alphaphenyl-ethyl phenol, mono-, di- and tri-alphatolylethyl phenol, mono-, di-, and tri-phenylmethyl phenol, and the corresponding mono-and di-cresols and xylenols.  The components need not be used in an absolutely pure condition so that the composition may comprise (1) the reaction product of a phenol and styrene, vinyl toluene, or a benzyl halide, and (2) the reaction product of phenol and at least two tertiary olefines, one of the olefines being a tertiary octene or nonene and another being isobutylene or a tertiary pentene, and the major proportion of the alkyl radicals in the reaction product being tertiary octyl or nonyl. As synthetic rubbers that may be preserved by the antioxidant mixture are specified polychloroprene, Butyl rubber (isobutylene-butadiene or isobutylene-isoprene copolymer), and butadiene-styrene and butadieneacrylonitrile copolymers.  The antioxidant mixture may be added to the natural or synthetic rubber in the form of latex, or may be milled into the rubber coagulum, the mixture being added alone or in the form of an emulsion, using an emulsifier such as a monovalent metal hydroxide, fatty acid, or organic soap. Alternatively, the components of the antioxidant mixture may be added to the rubber separately.  In one example, there is compounded in a vulcanizable composition of an oil-extended butadiene-styrene copolymer, an antioxidant mixture consisting of equal parts by weight of the reaction product of 1 mol of phenol and 2 mols of styrene and the reaction product of 1 mol of phenol and 2 mols of di-isobutylene plus 1 mol of isobutylene.  The preparation of the reaction products is described.  Reference has been directed by the Comptroller to Specification 758,474.

Abstract: 1,212,264. Automatic speed control. INTERNATIONAL COMPUTERS Ltd. April 2, 1969 [April 11, 1968], No.17562/68. Heading G3R. [Also in Division G1] The speed of a motor 10 energized through a variable switching device is measured by sampling the back e.m.f. of the motor armature during the off periods of the switching device. A 10 KHz oscillator 16 triggers a sawtooth generator 15, the output of which is clipped at 14 to a level set by the speed error signal from an amplifier 12. The clipped sawtooth triggers a generator 18 to provide a series of pulses, of width dependent on the speed error, which are amplified and fed to the motor 10. A mono-stable circuit 21 is also triggered by the 10 KHz oscillator 16 to provide 90 microsecond pulses, a generator 22 providing 5 microsecond pulses at the end of each 90 microsecond pulse. These 5 microsecond pulses, which normally occur during the periods when the motor is not energized serve to trigger a gate 23 which applies the motor armature voltage to a capacitor. The average voltage across the capacitor represents the speed of the motor. This value is fed back to the amplifier 12 where it is compared with a desired speed signal. The motor is a printed circuit permanent magnet type such as may be used to drive a magnetic tape machine. To ensure that the back e.m.f. is only sampled during the off periods a pulse width timing circuit may be inserted after the generator 18.
