Filed: 1967-06-20
Abstract: 1,237,862. Monitoring switch operations. ENGLISH ELECTRIC CO: Ltd. June 17, 1968 [June 20, 1967], No.28315/67. Heading G1U. In an arrangement for monitoring the operation of switch contact arrangements connected in parallel connected electric circuits which have substantially different impedances when contacts are closed, e.g. as in a circuit breaker 22 incorporating main interrupters 26, 27 and auxiliary interrupters 28, 29 in series with resistors 30 respectively across the main interrupters, a separate monitoring circuit 16-19 is provided for connection with each such electric circuit. Each monitoring circuit includes in series relation an A.C. test signal source, a test signal response monitoring arrangement for presenting an indication of the state of the associated switch contact arrangement and rectifier arrangements 33 preventing interaction between the test signal sources. Impedance matching arrangements 32 are associated with one or more monitoring circuits to match the impedances of the associated electric circuits such that the respective impedances to the flow of current in the monitoring circuits are less than a given value when the respective contact arrangements are closed. The separate A. C. sources are provided by respective secondary windings on a transformer 2 whose primary is coupled to a signal generator 1. The monitoring arrangement incorporates respective transformers 9 connected in the monitoring circuits, with secondaries connected to styli 13, which mark a moving sensitive paper 15 when current flow in the monitoring circuits is above a given amount, i.e. when the corresponding interrupter is closed. The impedance matching arrangements are transformers 32 with full bridge rectifiers 33 in their secondary circuits providing,current isolation between the separate monitoring circuits. Due to the impedance matching, each monitoring circuit responds only to the condition of the associated interrupter.

Title: Yarn testing machine
Inventor: WARREN GEOFFREY ALLAN
IPC: G01N3/14
Filed: 1950-11-22
Abstract: 694,585. Testing physical qualities of yarn. FIBREGLASS, Ltd. Sept. 26, 1951 [Nov. 22, 1950], No. 28511/50. Class 106 (ii). A yarn-testing machine, particularly for yarn formed from glass filaments, comprises a pair of yarn-supporting rollers b spaced apart in a horizontal line on a frame a, a loadable roller d between the rollers b and movable in a vertical line, a guide roller or rollers i having braking means m, j, k, n, o associated therewith, tractive means p adapted to exert a tension on the yarn r, a vertically movable slide c carrying the loadable roller d and an index finger h operable by the slide c. The roller d is loaded by a weight e carried on the lower end of the slide c, the weight of the slide c being counterbalanced by a weight el. The index finger h is movable over a graduated scale h<SP>1</SP> on the frame a. Method of operation. A length of yarn r, drawn from a reel s, is passed over the guiderollers i and the adjacent supporting roller b, then under the loaded roller d and over the other supporting roller b, the free end being wound on the drum p. With the loaded roller d in its lower position, and the drum p in motion a braking effect is applied to the guide-rollers i to stop them and thus cause the length of yarn between the rollers b to shorten. The resulting increasing tension in the yarn r causes the roller d and its slide c to rise and actuate the index finger h. When the breaking tension for the yarn is reached, the slide c is prevented from falling by a ratchet device t on the slide engaging pawls u on the frame. The breaking tension can then be accurately read from the position of the index finger h on the scale h<SP>1</SP>. If the yarn has only to pass a minimum tensile test, the friction brake is adjusted to allow the yarn to slide past it when subjected to the said tension, the length of yarn between the rollers b then assuming a constant length.

Title: Improved manufacture of new organo-silicon oxide condensation products
IPC: C08G77/00
Filed: 1947-03-24
Abstract: A method of making a mixed organo-siloxane having similar applications to those described in the Specification 654,054, and containing silicon atoms having hydrogen attached directly thereto comprises reacting at a temperature between 0 DEG  and 5 DEG  C. water with a mixture of halosilanes comprising an organohalosilane having halogen and monovalent hydrocarbon radicals as the only substituents attached to its silicon atom, and a monoorgano-dihalosilane having hydrogen, halogen and a monovalent hydrocarbon radical containing at least two carbon atoms as the substituents attached to the silicon atom of the molecule.  The monovalent organic radicals of the starting materials may be alkyl radicals, e.g. ethyl to octadecyl or higher, phenyl, naphthyl, p-methylphenyl, or p-ethoxy radicals, benzyl, or phenylethyl radicals.  The hydrolysis is preferably carried out in the presence of a solvent, e.g. an ether, aromatic or aliphatic hydrocarbon, or a halohydrocarbon and of a weak alkali, e.g. sodium acetate or bicarbonate.  By treatment with oxidising agents, hydrogen atoms of the polymers are replaced by oxygen atoms forming cross-links.  In an example a series of the following mixtures is hydrolysed at below 5 DEG  C. (1) ethyldichlorosilane and dimethyl dichloro-silane; (2) and (3) ethyldichlorosilane and ethylphenyldichlorosilane.

Abstract: 1475621 Binding mechanisms for balers DEERE & CO 10 July 1975 [17 July 1974 (2)] 29018/75 Heading AIF A baler forms cylindrical crop bales rotating about a horizontal axis and comprises a binding mechanism with a tubular arm 84 through which twine 97 passes, an inclined or vertical rock shaft 86 connected to one end of the arm causing the other end of the arm to swing arcuately thereby moving along the length of the rotating bale so that twine is drawn spirally round the bale. A piston and cylinder 90 controls the rock shaft movement and the hydraulic circuit of the cylinder includes at least one variable orifice to adjust the rate of movement. A cutter, in housing 103 mounted on a compressor 72 of the baler, comprises a knife 118 on pivot 120 and biased by a spring 124 against an adjustable stop 122, and an anvil 110 on one end of a pivoted bell crank lever 105 pivotally connected by a link 108 to a lever on pivot 102. A spring 114 biases the cutter into the Fig. 5 position, but when arm 84 moves into a transverse position it engages lever 101 and causes anvil 110 to move against knife 118 to sever twine 97 (Fig. 4). The twine is clamped between the knife and anvil until the piston of cylinder 90 is extended to commence the swinging of arm 84 along the bale. In the fore and aft position of arm 84 (dashed lines of Fig. 5), the dangling end of twine 97 is readily picked up by the compressor rolls 26, 28 of the baler to commence the binding operation.

Title: Process for spin-dyeing polymers of acrylonitrile containing acid groups or co-polymers thereof containing acid groups
IPC: C08L33/04
Filed: 1975-07-11
Abstract: Spinning solutions of acid-modified polymers or copolymers of acylonitrile are spun-dyed with quaternary triazoleazoaniline dyes in the form of their tetrafluoroborate salt. The cation of the azo dye is a methyl- or ethyl-quaternised triazolium radical which is methyl- or ethyl-substituted in the 1-position at the nitrogen atom and may be methyl-substituted in the 5-position; the coupling component is an aniline derivative which can be substituted in the benzene ring by halogen, alkyl, alkoxy or acylamino and whose nitrogen atom can be mono- or disubstituted by lower alkyl, aralkyl or aryl groups. The fibres obtained have a deep red shade and high brightness; especially the light fastness, rub fastness, fastness to dry heat setting and pleating, wash fastness and steam fastness are remarkably high. The use of the dye causes only extremely slight staining of the coagulation and drawing baths. The molecular dispersion of the dye in the spinning solutions and filaments has the effect that these are transparent, speck-free and non-matt and rules out any blockage or mechanical wear of the spinneret as occurs with the use of colour pigments.
