Patent GB-338976-A (GB)
Title: Process for the manufacture of improved shuttles for weaving
IPC: D03J5/00
Filed: 1929-08-30
Abstract: 338,976. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Aug. 30, 1929. Shuttles.-Wooden shuttles for weaving are made by impregnating the wood before or after working with an indifferent solid chlorinated organic material. When the impregnating substance has a high melting point, it may be mixed with a lower melting addition as paraffin or mountain wax. Suitable substances are solid higher chlorinated hydrocarbons such as solid chlorinated naphthalenes with a chlorine content of 45-60 per cent and solid chlorinated diphenyl. In an example, ash is dried at 120‹ C., covered with melted chloronaphthalene, heated under pressure, and then worked up. Shuttles so made are stronger, have a smooth surface, are insensitive to moisture, and are of twice the weight of those made from the untreated wood. In another example, shuttles are made from horn beam treated with a wax prepared according to example 1 of Specification 309,421, [Class 22, Cements &c.]. Shuttles produced from very dense persimmon wood may also be improved by the impregnation. In another example, redbeech wood for making shuttles is introduced into twice its weight of molten chlorinated diphenyl in an autoclave which is then evacuated, the wood being removed while the diphenyl is still liquid.

Abstract: 380,261. Mercury-vapour rectifiers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 24, 1931, No. 26644. Convention date, Sept. 30, 1930. [Class 39 (i).] In a rectifier having a metallic or a glass container, two or more grids which are disposed in different planes in anode sleeves or arms, one above the other, are heated by means independent of the discharge. Grids g, Fig. 1, formed of wire mesh or consisting of concentric cylinders may be heated by an auxiliary transformer h. A grid of wire mesh and a grid consisting of surfaces extending in the direction of the sleeve axis may be mounted one above the other. Grids consisting of concentric cylinders may be inclined to the sleeve axis, Fig. 5 (not shown). In a modification, a liquid or gaseous heating medium is passed through hollow grids g, Fig. 2, connected in series or in parallel. The grids may be formed of conducting or of semiconducting material, such as graphite, and may be connected to transformer tappings f, Fig. 1, to prevent back-ignition. Reference has been directed by the Comptroller to Specification 352,389.

Title: Metallic wire bars
IPC: B23C3/14
Filed: 1935-09-30
Abstract: 443,828. Making wire bars. AMERICAN SMELTING & REFINING CO., 120, Broadway, New York, U.S.A. Sept. 30, 1935, No. 26971. Convention date, Sept. 29, 1934. [Classes 83 (ii) and 83 (iii)] Milling-machines.-A process for producing a metal casting such as copper, brass or aluminium wire bar consists in casting the wire as usual in a horizontal mould, milling off the oxidized surface of the cast bar and further milling the sharp edges along the sides of the milled surface to produce rounded or bevelled edges extending along the entire length of the casting. The cast bars 4 with tapered ends are mounted in pairs on a reciprocating table 2 provided with pneumatically-operated clamping and straightening devices 3. A pair of motors 5, 5 are carried on mountings 13 slidable in inclined guides on the base and adjusted to and from each other by means of a hand-operated crossshaft 10 and worm gearing 8, 9. The milling- spindles 18 are driven from the motors by reducing gears 16 and carry cutters 19, which during automatic reciprocation of the table remove the scale from each of the bars 4. The edges of the bar adjacent the milled surface are rounded off by means of a pair of cutters 20, Fig. 4, splined on a cross-shaft 21 driven by worm gearing 34, 37 from the milling spindles 18. The chips from the operation drop into troughs 25 and may be removed by conveyers (not shown). The bar clamping means include serrated members 26, 27 and a pneumaticallyoperated yoke 29 carrying pins 28 which engage the upper surface of the bar. The rounding cutters 20 may be slid along their supporting shaft by forked members 40 to enable these cutters to follow the taper of the bar ends.

Title: Strip tensioning apparatus
IPC: B21D1/05

Abstract: 1,113,667. Stretching; rolling; improving physical properties. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (St. Chamoid, Firminy, St. Etienne, Jacob-Holtzer). 25 June, 1965 [3 July, 1964], No. 27064/65. Headings B3E, B3M and B3V. Strip-tensioning apparatus comprises two sets of rollers arranged to have a strip pass in a sinuous path in friotional engagement with the roller surfaces of first one then the other set; positive drive means for rotating a roller in each set at accurately determinable different speeds so as to feed a strip past said first then past said second set while imposing a prescribed elongation to the strip as determined by the difference between said speeds; and means for rotating the remaining rollers of both sets by way of yielding connections whereby said remaining rollers will participate in feeding and tensioning the strip in a substantially slip-free manner. Strip is tensioned by passage in a sinuous path around rollers a 1 -a 5  and then around rollers b 1 -b 5 , being treated, e.g. rolled, alternately bent or otherwise worked, as it passes in stretched condition between the rollers a 5  and b 1 . The rollers are driven by a motor h through differential gearing i and gears d, e and f, and powder magnetic slip clutches m. The spider of the differential i is driven by a worm j so that the speeds of the rollers a relative to the speeds of the rollers b may be varied. The clutches m are set to disengage at a predetermined torque. The torque, on the shafts of the rollers a 5  and/or b 1  is measured and the resulting control signal varies the energizing currents of the slip couplings m. The gears driving rollers a 5  and b 1  may be of smaller and larger diameters, respectively, than the remaining gears of the rollers of their respective sets.

Abstract: 376,562. Pipe joints. STAVELEY COAL & IRON CO., Ltd., Staveley, near Chesterfield, and FAWCETT, P. W., The Homestead, Hope, both in Derbyshire. Oct. 2, 1931, No. 27458. Addition to 372,669.

Title: Pulse Amplitude Measurement Technique.
IPC: H03K9/02
Filed: 1967-06-14
Abstract: 1,193,104. Measuring pulse amplitude. HOFFMAN ELECTRONICS CORP. 14 June, 1967 [14 June, 1966], No. 27541/67. Heading H3T. [Also in Division G1] In a circuit for measuring the amplitude of the second of a pair of pulses, the pulses are applied to a switch, e.g. an FET 15, Fig. 2, which is opened, when the second pulse is substantially at its maximum amplitude, in response to a signal derived from the first pulse, and the switch output is connected to a storage device, e.g. a capacitor 28 which indicates the maximum amplitude of the second pulse. A level detector 12 produces standardized pulses 42, 43, Fig. 3, corresponding to the pulses 40, 41 and a delay circuit 17, which may be a clocked counter, having a delay slightly less than the spacing of the pulses 42, 43 provides pulse 45 which, with pulse 43, causes an AND gate 19 to feed pulse 46 to delay circuit 21 to produce a pulse 47 starting just before the peak of the pulse 41. The pulse 47 triggers a monostable circuit 22 to generate a pulse 48 which passes through amplifier 24 to cause the FET to conduct. To overcome undesirable triggering of the monostable circuit by noise signals another level detector and AND gate may be included after the delay 21 and these only trigger the monostable circuit when the second pulse 41 has reached a high proportion, e.g. 90%, of its maximum value. In an alternative system, Fig. 4 (not shown), where the spacing of the pulses 40, 41 is accurately known, the delays 17, 21 and the AND gate 19 are replaced by a delay circuit (57) having a delay slightly greater than the pulse spacing so that the leading edge of the delayed first pulse which triggers the monostable circuit occurs just before the peak of the second pulse. The source impedance connected to the terminal 10 is low to permit rapid charging and discharging of the capacitor 28.
