Patent GB-408670-A (GB)
Title: Improvements in and in the manufacture of flat strip electric conductors
IPC: H01B7/08
Filed: 1932-10-13
Abstract: 408,670. Weaving diagonally warped strips. WILSON, W. H., Berrynarbor, Ashcombe Avenue, Surbiton, Surrey. Oct. 13, 1932, No. 28619. [Classes 142 (i), 142 (ii), and 142 (iv).] A flat strip conductor for winding into inductance coils comprises a number of insulated wires 1, Fig. 1, lying side by side for the greater part of their length but transposed at regular intervals 2, so that in a moderate length of the strip each wire occupies for equal lengths of the strip substantially every position throughout the width of the strip. The wires may be wound directly upon a former into the form the strip has to take, the wires being secured, if desired, by an adhesive tape wound between the turns of the strip. The strip may be formed as a fabric having warp wires which are secured together by a weft thread 4 woven with them, the fabric being made on a loom in which the warp wires are transposed at regular intervals. Figs. 4 and 5 show a loom for forming such a fabric, the warp wires 1 being drawn from bobbins 11, on a rotary disc 12, through warp guides 57 and heddle frames 19 from which the wires converge to guide rollers 30 and then pass to draw-off rollers 32. A shuttle 34 which weaves a silk weft thread into the fabric operates adjacent the guide rollers 30 in the shed formed by the heddles. The warp guides 57 comprise a series of rollers 16, 17, Fig. 7, contained in a flattened oval race and which are caused to move round the race a step at a time by a sprocket 18. The wires 1 pass individually through the rollers 16 which are perforated. The sprocket 18 is mounted on a shaft 54, Figs. 1 and 2, to which a rotary step by step motion is imparted by a ratchet mechanism 50-53 operated by a cam 49 which is driven from a shaft 46 through gearing 47. The bobbin-carrying disc 12 is mounted on a shaft 58 which is concentric with the shaft 54 and is driven uniformly, through gearing 47, 48, from the shaft 46 which is driven by the main shaft 28 of the machine through gearing 45. Pairs of heddles 20, 21 and 22, 23, Fig. 10, which, to allow for the transposition of the warp wires, are so formed as to engage the wires only from above and below, are reciprocated in the frames 19 by connecting rods 24, 25 operated through gearing from the main shaft 28, Figs. 1 and 2. The shuttle 34 is reciprocated horizontally by a toothed segment 39 which is rocked to and fro by a link 40, the end of which engages a cam slot 41 in a wheel 42 upon the main shaft 28. The operation of the loom is such that the heddles are reciprocated between successive traverses of the shuttle and after'say three such traverses the warp guides are moved through a step while the warps are free of the heddles. The woven strip when wound into coils, as for instance the double coils described in Specification 266,428, [Class 37], may be impregnated with paraffin or other wax and such coils may be provided with a coil or with a closed or nearly closed magnetic circuit consisting of finely divided material of high permeability agglomerated with a binder.

Title: Improvements in connection with rotary electric switches
IPC: H01H19/11
Filed: 1948-11-04
Abstract: 648,576. Mechanical switches. REVO ELECTRIC CO., Ltd., FELTON, A. E., and PRICE, F. H. Nov. 4, 1948, No. 28630. [Class 38 (v)] A positioning tor locating device for a rotary switch comprises an operating spindle 6, a star wheel cam 8 mounted on the spindle, a pin or shaft 11 with a collar 10, a bifurcated block 12 having forked limbs 13 supporting the pin 11, a spring 15 urging the block 12 upwardly so that the collar 10 engages the cam 8 and guide plates 18, 19 having slots 17 engaged by the ends of the pin 11. The slots 17 are of inverted V-formation so that the path of movement of the pin 11 is determined by the direction in which the operating spindle is rotated. Thus whichever way the spindle is turned, the pin 11 and block 12 are thrust forwardly and away from the spindle 6 by a lobe of the cam 8 until the lobe clears the collar 10. The collar 10 then moves into the next dwell of the cam as the pin 11 returns to the apexes of the slots. The arrangement of the slots is such that the operating spindle 6 must be turned through an angle substantially equivalent to the angle between adjacent switch positions before the pin 11 and block 12 are released by the movement of the collar 10 into the succeeding dwell of the cam to locate the switch in the next position.

Title: Improvements in timers or safety cut-outs for fuel-burning appliances
Inventor: POWELL ANTHONY
IPC: F16K31/48
Filed: 1963-07-19
Abstract: 1,098,811. Valves. SEEMARK SWITCHES Ltd. July 17, 1964 [July 19, 1963], No. 28714/63. Addition to 981,751. Heading F2V. [Also in Division F4] A timer or safety cutout for a gas burner comprises an actuator which operates a valve (not shown) to shut off the supply of gas to the burner after it has been rotated a predetermined amount by a spring- driven wheel 11 whose movement is controlled in response to the oscillation of a heat conducting plate 19. The plate 19 has a bent portion 22 and divided legs 21 and is pivotally mounted at 23 on a plate 13. The legs 21 are urged into contact with a bi-metallic strip 14 when the strip is cold, by a spring. The strip 14 is mounted in a sling 15 and a screw adjusts the end pressure exerted by the sling on the ends of the strip 14. The strip carries a shaft which pivotally supports a double-pawl escapement piece, operatively associated with the teeth of the wheel 11, and an arm 36 having an end 38 engaging the plate 19. In operation the wheel 11 is rotated to wind up its drive spring and heat is applied to the end 22 of the plate 19. Heat is conducted to the strip 14 which " snaps " into an outwardly bowed position and pawls then allow the wheel 11 to rotate a half tooth-pitch distance. Arm 36 also moves the plate 19 out of contact with the flame and strip 14 " snaps " back on cooling to allow the wheel 11 to rotate a further half-pitch and the plate 19 to contact the flame. The cycle is repeated until the actuator connected to wheel 11 rotates sufficiently to close the gas supply valve. The device may be used to control oil or solid fuel appliances with a heated plate replacing the burner.

Title: A device for detecting breakage of thread or the like in a textile machine
IPC: B65H63/028
Filed: 1959-08-21
Abstract: 903,308. Detecting thread breakages. RUTI MACHINERY WORKS Ltd. Aug. 21, 1959 [Aug. 22, 1958], No. 28735/59. Class 120 (2). In a device having a feeler for each thread such that upon thread breakage a feeler cooperates with an electric contact to control a circuit, at least part of each feeler is of magnetic material and positioned in a magnetic field. Each feeler, which comprises an arm 1 and an arcuate part 3, is pivoted at 2 and biased against thread tension by the field of a rod magnet 4 so that a circuit through contact bars 2, 6 is closed upon thread breakage. Each feeler is mounted in a sector 5 with profiled ends so that a number of sections may be mounted coaxially to form a cylinder. The magnetic field may be varied by rotatable adjustment of the rod 4 and augmented by a spring or weight. Either or both of the rod 4 and part 3 may be electromagnets. A feeler may be locked in an inoperative position (shown in chain-lines in Fig. 1) by the end 12a of a spring 12. In a modification, Fig. 4, the whole feeler 13 is of magnetic material and is mounted in an insulating block to slide in contact with a conducting bar 14. When a thread breaks the feeler 13 is attracted upwards by a rod magnet 16 to close a circuit between contact-bars 14, 17. The magnetic attraction of the feelers increases with proximity to the rod magnet, thus ensuring good contact pressure and rendering the device particularly suitable for use in handling fine yarns.

Title: Process for the preparation of salts of sulpho-carboxylic acid esters of alcohols
IPC: C07C303/32
Filed: 1938-10-04
Abstract: 519,230. Metal salts of sulpho carboxylic acid esters. HARRIS, B. R. Oct. 4, 1938, No. 28816. Convention date, Feb. 11. [Class 1 (iii)] [Also in Group IV] Salts of esters derived from higher alcohols containing at least 8 carbon atoms in the molecule and sulphocarboxylic acids having less than 8 carbon atoms in the molecule are converted into different salts of the said esters by passing aqueous solutions or colloidal dispersions of the salts into contact with base exchange materials such as zeolites, greensands, glauconites, harmatones and certain synthetic resins containing the desired cation. By this means salts of heavy metals having increased solubility in cold water may be obtained. Hot solutions of the salts having low solubility are usually employed in order that they may be as concentrated as possible. The esters may be obtained according to the process of Specification 377,249, e.g., chloracetylchloride is reacted with lauryl alcohol and the resulting ester treated with potassium sulphite. In an example, in which the base exchange material used is the substance known by the Registered Trade Mark "Cristallite," laurylpotassium sulphoacetate is passed through a bed of base exchange material containing magnesium cations obtained by treating the bed with magnesium chloride. The higher alcohols from which the esters of sulphocarboxylic acids are derived comprise those obtained from oils and fats such as corn, cottonseed, sesame, coconut, sunflowerseed and soya bean oil, lard, and tallow. Sterols, e.g., cholesterol, phytosterol and sitosterol, hydroaromatic alcohols, e.g., abietol, linalool, citronellol, geraniol, branch chain alcohols, e.g., 2-ethylhexanol-1 and 2-butyltetradecanol and hydroxy fatty acid acids and esters, e.g., alpha-hydroxy stearic acid, alpha-hydroxylauric acid, dihydroxy stearic acid, alpha-hydroxypalmitic acid, ethyl ricinoleate, and cetylhydroxystearate may also be used. Alcohols obtained by oxidation of hydrocarbons and the reduction of aldehydes are mentioned. Halogens and ether, ester, sulphonic and sulphate groups may be present in the higher alcohols and derivatives of polyhydric alcohols such as sucrosemonolauric acid ester, mannitolmonopalmitic acid ester, maltosedicaproic acidester, sorbitolmonooctylether, pentaerythritolmonolauryl ether, monolaurin, monomyristin, diolein, dicaproin, glycerolmonolaurylether, glyceroldicetylether, diethyleneglycolmonostearic acid ester and ethyleneglycolmonolauricacid ester are suitable higher alcohol derivatives. Monopalmitinsulphobutyrate, dioctylmono and disulphosuccinate, distearylmono and disulphosuccinate, monopalmiticacid ester of ethylene (or diethylene) glycolsulphopropionate are specified sulphocarboxylic esters. Sulphoglutarates, sulphovalerates and sulphofumarates are also mentioned. The halogens and the following groups may also be present in the acid radicle : OH, NH2, NR2, CONR2, CHO, CO, COOH, COOR, SO3H, CN, SCN, SH, PO3 H32, PO4H2 and OR wherein R is alkyl, aryl of cycloalkyl.
