Title: Improvements in sewing machines
Inventor: LESLIE IVAN ALEXANDER
IPC: D05B55/14
Filed: 1959-09-05
Abstract: 892,898. Sewing machines. SANKEY & SONS Ltd., JOSEPH. Nov. 30, 1960 [Sept. 5, 1959], No. 30373/59. Class 112 In a sewing machine in which the needle bar is slidably mounted in a member so as to rock with the latter in a vertical plane, said member is carried by a slidable part which is adjustable between an upper position in which it rocks about an axis situated above the plane of the work support, and a lower position in which it rocks about an axis situated below the planes of the work support. A needle bar 8 is slidable in a block 10 and is driven by a crank 7 on the arm shaft 6 of the machine. Block 10 is formed with an arcuate rib 11 slidably disposed between a pair of arcuate ribs 12, 13 on a stationary block 38, whereby block 10 oscillates on reciprocation of the needle bar. A presser bar 16, slidable in block 10, is biased downwardly by a spring 18 and carries a presser foot 17. A bar 15 is pivoted at one end, at 22, to the machine frame, its other end is forked, as at 23 to straddle the presser foot 17, and it is biased upwardly by a spring 24. Bar 15 is connected by a link 31 to one arm 30 of a bell-crank lever pivoted at 28 to the presser bar. A pin 25 on the needle bar is adapted, during the upward stroke of the latter, to engage the other arm 26 of the bell-crank lever, whereby the presser bar is raised and bar 15 is lowered. End 23 thereby engages the work while the needle and the feeding presser foot 17 are disengaged therefrom. Block 38 may be raised or lowered by a lever 39, pivoted at 41 to the machine frame and biased upwardly by a spring 50, to position the centre of curvature of rib 11 either above the work for normal feeding, or below the work for reverse feeding. A block 47, formed with a notch, the respective edges 45, 46 are engageable by a pin 44 on lever 39, is movable horizontally by rack and pinion means 48, 49 to regulate the stitch length.
Patent GB-966755-A (GB)
Title: Improvements in or relating to circuit arrangements employed in telegraphy
IPC: H04L25/22
Filed: 1960-09-02
Abstract: 966,755. Telegraphy. BUDAVOX BUDAPESTI HIRADASTECHNIKAI VALLALAT. Sept. 2, 1960 [Sept. 2, 1959], No. 30394/60. Heading H4P. The invention provides a doublesingle current converter for connection between a two-way simplex line and a single-current teleprinter, wherein the circuit including the teleprinter receiving magnet includes a network which compensates for the impedance of the magnet. The teleprinter transmitting relay A and receiving magnet EM are in independent circuits so that the receiving magnet cannot cause characteristic distortion of the signals when the teleprinter is transmitting. Operation of teleprinter transmitting contacts SK causes polarized relay A to reverse contacts a, thereby sending doublecurrent signals over the simplex line. Receiving magnet EM provides a local record. When receiving double-current signals from the other simplex line, relay B causes receiving magnet EM to operate. The receiving magnet is connected to the transmitting contacts SK by way of a network which compensates for the impedance of the magnet and which includes a relay U. By means of diode G and impedances C2, R2, R3, it is ensured that C2 can charge rapidly during space bits but discharge only slowly during mark bits, so that the relay will switch only when a mark of long duration, i.e. a switching signal, is received. For duplex operation the network no longer connects to the transmitting contacts but connects direct to the supply.

Title: Improvements in textile fibres and yarns and in fabrics made therefrom
IPC: D03D27/00
Filed: 1934-10-24
Abstract: Cellulosic textile fibres or yarns or similar unwoven textile materials are given a permanent or semi-permanent series of local distortions which are set in the deformed position by the solidification within or upon the fibres or yarn of a substantial quantity of a synthetic resinous material; the deformation may be rendered resistant to washing by insolubilizing the condensation product and fabrics woven from the treated yarns or from yarns spun from treated fibres may be mercerized and/or subjected to acid treatment.  Yarns for pile fabrics are produced by untwisting treated yarns and then twisting them in the reverse direction. The distortion of the yarn or fibre may be effected by fluted rollers or the yarn may be spirally wound and the distortions set by heat and pressure. Two examples of setting mixtures are given. Specifications 291,473 and 291,474, [both in Class 42 (i)], are referred to.
Patent GB-698996-A (GB)
Title: Process for purifying the polychlorophenoxy-aliphatic monocarboxylic acids
IPC: C07C51/487
Filed: 1951-12-31
Abstract: Technical polychlorophenoxy-aliphatic monocarboxylic acids may be purified by mixing an alkali metal salt of the acid with an alkali metal hypochlorite in aqueous dispersion; decomposing any excess hypochlorite in the mixture and acidifying the mixture to precipitate the polychlorophenoxy-aliphatic monocarboxylic acid, the hydrogen ion concentration of the mixture being maintained at a pH of at least 0.5 throughout the precipitation.  The excess of hypochlorite in the mixture may be decomposed by heating the dispersion at boiling-point, preferably at a pH from 7 to 8; alternatively, it may be decomposed by the addition of a small amount of hydrogen peroxide.  After the decomposition of the excess hypochlorite, the hypochlorite-free dispersion is acidified at a pH of 0.3 or higher with hydrochloric acid to precipitate the polychlorophenoxy - aliphatic monocarboxylic acid.  In the examples: (a) technical 2,4-dichlorophenoxy acetic acid is dispersed in water and neutralized with potassium hydroxide, sodium hypochlorite is added, the excess being decomposed by heating, and after filtering, the filtrate is acidified with hydrochloric acid at a pH greater than 0.5 to give purified 2,4-dichlorophenoxyacetic acid; (b) potassium 2,4-dichlorophenoxyacetate is prepared by neutralizing the technical acid with potassium hydroxide; potassium hypochlorite is added, the excess is decomposed by boiling and the salt solution is acidified with hydrochloric acid to give purified dichlorophenoxyacetic acid; (c) sodium 2,4-dichlorophenoxy acetate solution is treated with sodium hypochlorite, the excess of which is decomposed by the addition of hydrogen peroxide; the resulting mixture is acidified to give purified 2,4-dichlorophenoxyacetic acid; (d) technical 2,4,5-trichlorophenoxyacetic acid is neutralized with sodium hydroxide and a dispersion of the sodium salt in water is treated with sodium hypochlorite, the excess being decomposed by heating; the resulting solution is acidified with hydrochloric acid to give purified 2,4,5-trichlorophenoxyacetic acid; (e) technical 2,4-dichlorophenoxy acetic acid is converted to its sodium salt which is mixed with water and treated with sodium hypochlorite solution; the excess hypochlorite is decomposed by treating with hydrogen peroxide, the resulting solution is acidified with hydrochloric acid to give purified 2,4-dichlorophenoxy acetic acid.  Other technical polychlorophenoxy - aliphatic - monocarboxylic acids such as b -2,4-dichlorophenoxypropionic acid, a - and b -2,4,5-trichlorophenoxy propionic acid, 2,3,4,6-tetrachlorophenoxy acetic acid and pentachlorophenoxy acetic acid may be purified similarly.

Title: A device for measuring liquids and gases
IPC: G01F23/14
Filed: 1937-11-11
Abstract: 511,176. Fluid meters, switches. GIRTEN, J. Nov. 11, 1937, No. 31049. Void. Convention date, Nov. 23, 1936. [Classes 54 and 69 (i)] [Also in Group XXXVII] An apparatus, stated to serve for the measurement of liquids and gases and intended in the form shown for the measurement of liquids, comprises a container 27 into which the liquid is introduced through a tube 2 the perforated lower end of which is surrounded by a cup 3 forming a liquid seal. The air expelled during filling is conducted by tubes 5, 6 to chambers 7, 8, from which it escapes by a pipe 9 having an outlet controlled by a valve 10. The pressure produced in the chamber 8 by the air flow depresses a diaphragm 11 and causes a needle 12 secured to it to contact with mercury in a cup 13, thus completing the circuit of a motor 26 which operates a counting mechanism 20. On withdrawal of liquid, air is drawn into the tank, and the suction thereby produced in the chambers 7, 8 depresses the diaphragm 15 which closes the chamber 17, thus causing a mercury switch similar to the first to close the motor circuit. The motor then operates the counter 20 in the reverse direction, owing to its polarity having been reversed by a switch 21 which is operated by an arm 25 which engages under the head of a closure inserted into the top of the tube 2 when the container has been filled. It is stated that gases may be measured by connecting the gas conduit to the chambers 7, 8 of the mercury switches, and that the gas may be supplied from a container by displacing it with water.

Title: Moulding machine
IPC: B22D17/32
Filed: 1975-07-25
Abstract: 1509036 Injection mould filling control BUCHER - GUYER AG MASCHINENEFABRIK 25 July 1975 [7 Aug 1974] 31165/75 Heading B5A In an injection mould closing unit operated by a hydraulic piston and cylinder 6-9, the degree of mould filling is measured by an electrical displacement transducer A or B comprising two components attached to the piston 7 and the cylinder 6 respectively. One form of transducer B comprises a housing 29 attached to the cylinder 6 and a member 32 positioned on a rod 28 attached to the piston 7. The member 32 is held to the rod 28 by magnets and during mould-closing it moves with the rod 28 until the gap 34 is closed and it contacts the housing whereupon it is forced to slide along the rod until the mould is closed. The injection pressure then causes a slight opening of the mould which results in a reverse movement of the rod 28 and the member 32 to open gap 34 and reduce gap 33. Coils 30 in the housing 29 produce signals coresponding to the changes in the gaps 33, 34 and since they are connected as the arms of a bridge circuit produce an out of balance signal which is amplified for control of the machine parameters, e.g. injection and after pressures, holding time, and shot volume. A similar transducer A may be positioned with its housing magnetically fixed to the cylinder flange 5 and a member 20 (Fig. 2, not shown) magnetically attached to the piston rod 8 and moving within the housing (15) which carries the gap sensing coils (20a). An alternative C, Fig. 3, to transducer A comprises a member 38 bolted to the cylinder flange 5 and a member 45 magnetically retained on the piston rod 8. Member 45 is movable between stops 46 on the member 38 and during mould closing contacts one of the stops and slides along the piston rod. When the mould halves separate slightly during injection the member 38 moves off the stop 46 causing a change in the deflection of a spring 42 extending between the members 38, 45. The resistance of strain gauges 48 is thereby altered and as before an out of balance signal is produced in the bridge to which they are connected for indication or control purposes.

Filed: 1971-07-02
Abstract: 1351837 Punching; shearing; bending EXCEL MFG Ltd 2 July 1971 [9 July 1970] 31215/71 Heading B3W and B3E In a punch press, a main beam 34 is pivoted on the press frame at 33, the shorter portion 35 of the beam supporting a punch 79 and the longer portion 36 actuating one or more further tools such as a shear 56, a shear 64 for cutting angle iron and a press brake 65. Fluid cylinders 37 and 38 mounted in trunnions 39, 40 on the frame are connected to the portion 36 and a valve (93) and manually operable valves 1-4, Fig. 11 (not shown), enable hydraulic fluid to be fed selectively to either side of either piston. To actuate the shears &c. with normal power a pedal 91 is depressed which causes piston and cylinder device 37, which is preferably of larger volume than the device 38, to lower the beam portion 36, the underside 66' of the beam actuating the shear 64 &c. The shear 56 is actuated through a secondary beam 49 pivotable about trunnion 50. The stroke length of the beam when shearing is determined by the position of an adjustable stop 151 on a control rod 148 which when the beam portion 36 reaches the lowermost position reverses the position of the valve 93 to supply fluid to the underside of the piston of cylinder 38 for quick return of the beam. For actuating the shears, &c. with maximum power the cylinder devices 37 and 38 are coupled. For punching with normal power, a pedal 121 is depressed and fluid is supplied to the underside of the piston of device 37. An adjustable stop 152 determines the stroke length. The device 38 may be coupled to the device 37 for maximum power. Spindles 83<SP>1</SP> at the end of the beam portion 34 engage under detents 84 in links 82 pivoted to the punch spindle 78. A handle allows the links to be pivoted against spring bias out of engagement with the spindles 83<SP>1</SP>. A hold down 60, Fig. 16, is rotatable to bring a selected strip 61 into operation.
