Patent GB-232927-A (GB)
Abstract: 232,927. Prentice, G. E. April 28, 1924, [Convention date]. Sliding-clasp fastenings.-In a fastener for garments, shoes &c., of the kind wherein two strips 13, 14 are locked together and unlocked by a clasp 12 sliding on interlocking members on the strips, the interlocking members consist of two helically-wound springs 10, 11, one coiled in a right and the other in a left-hand direction. The strips 13, 14 are permanently united at one end by a clip 15 and the springs 10, 11 terminate in stops 16, 17 at the other end. The coils of the springs may be flattened after winding to decrease the thickness, or made egg-shaped, and the forward ends 33a, Fig. 7, may be bent downwardly so that they interlock more positively. The springs may be attached to the strips by threading them spirally through the material of the strips just within the selvages, or they may be united to the strips during the manufacture by weaving. The change in elevation from one convolution to the next of each spring is preferably wholly or mainly confined to those parts 35, Fig. 7, which engage the strips so that the parts 36 which project, beyond the edges of the strip lie substantially perpendicular to such edges. The slider 12 is bent up from sheet metal to the shape shown in Fig. 4, with flanges 28, 29 to form side channels, and the wings are held together by a rivet 30 to which the pull device 32 is pivoted, or the rivet may be formed by a narrow extension 44, Fig. 9, of one wing 38, bent back to pass through holes in the wings.

Title: Means for ensuring fluid-tightness between two gases separated by a wall through which passes a rotating shaft
IPC: F04D5/00
Filed: 1957-07-23
Abstract: 820,348. Stuffing-box substitutes. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. July 23, 1957 [Feb. 12, 1957], No. 23344/57. Class 122 (5). Sealing means for a rotary shaft 1 passing through a wall 2 separating two gases comprises a sleeve 3 closely surrounding the shaft and secured in fluid-tight manner to the wall and forming around the shaft a central annular chamber 4 in which terminate two helical grooves 5a, 5b of opposite hand, the grooves being formed either in the sleeve, as shown, or in the shaft and having a depth which progressively decreases away from the chamber, auxiliary packing means, such as the sealing ring 9, being provided to prevent leakage when the shaft is at rest and arranged to come into operation when or just before the shaft comes to rest. In operation, when the shaft 1 rotates, the helical grooves 5a, 5b operate as pumps to form a vacuum in the chamber 4 and oppose leakage of gas from each side of the wall. The sealing ring 9, which may be of polytetrafluoroethylene, closely surrounds the shaft and has a conical exterior surface which is forced against a corresponding conical seating 8 on a plate 6 secured to the wall, the ring being thereby pressed on to the shaft, by a control mechanism when the shaft stops or its speed falls below a predetermined value. The ring is moved axially out of contact with the seat when the shaft begins to rotate or when its speed exceeds the predetermined value. The internal surface of the sleeve and the portion of the shaft surrounded thereby may be bi-conical with a maximum diameter in the vicinity of the chamber 4. The invention is described as applied to sealing the shafts of rotary compressors circulating hexafluoride of uranium in a nuclear reactor, the wall 2 separating the hexafluoride of uranium at low pressure from nitrogen at substantially the same pressure. As an alternative to the sealing ring 9, leakage of gas from one side of the wall to the other when the shaft is stationary may be prevented by a vacuum pump coupled to the chamber 4 and arranged to operate as soon as the shaft stops or when its speed falls below a predetermined value.

Title: Measuring apparatus for setting the work in cylinder reboring machines
IPC: B23B29/034
Filed: 1933-08-23
Abstract: 404,581. Cylinder - boring machines. KRAUSE & CO. AKT.-GES., E., 13, Franzosische Strasse, Berlin. Aug. 23, 1933, No. 23459. Convention date, Dec. 27, 1932. [Class 83 (iii).] A cylinder boring machine is provided with a rotatable and axially movable gauging device the centre line of which is maintained parallel to and at a fixed distance from that of the boring spindle, while the work table is adapted to be fixed at two positions, the distance apart of which correspond to the distance between the boring spindle and gauging device. The gauging device is housed in a tube 20 carried by brackets 1, 2 in a position parallel to and at a fixed distance from the boring spindle 3, a pin 4 projecting from the end is connected by rack mechanism to a dial gauge 9 so that by rotating the tube 20 and moving it axially within a cylinder bore the latter may be set up on the slidable worktable in such a position that only a minimum of material will have to be removed to true it. The work table is then moved along a distance determined by the notched bracket 12 thus bringing the work into exactly the same position relative to the boring spindle as it previously stood in relation to the axis of the gauging device.

Title: Improvements in or relating to electronic valves
IPC: H01J19/42
Filed: 1959-07-08
Abstract: 874,723. Thermionic valves. SIEMENS & HALSKE A.G. July 8, 1959 [July 8, 1958], No. 23466/59. Class 39(1). In an electronic valve comprising a cathode 1 with two parallel flat emissive surfaces, a control grid 2, a screen grid 3 and an anode 5, at least one beam-forming plate.4 is located between grid 3 and anode 5 in a plane parallel to the flat surfaces of the cathode. The control grid is under tension on two supports so that each part of the control grid extending between these supports is parallel to the flat cathode surfaces. As shown, the screen grid, not under tension has portions disposed at an angle of 45 degrees to the flat cathode surfaces. The electrode spacings and various grid dimensions are specified. The electrode assembly is supported by two mica discs, one of which is fixed in a constriction of the valve envelope. In order to reduce the capacitances to the end turns of the grid and to increase the mechanical stability of the cathode, its. dimension perpendicular to the flat surfaces is smaller over its end portion than over its middle portion. The inside of the valve envelope is coated with metal by vaporization in order to exclude effects which would cause the valve to exhibit a frequency dependent internal resistance. The contact pins of the valve are gold-plated.

Title: New textile resist printing process
Inventor: WYLD ARTHUR HUTCHINSON
IPC: D06P5/12
Filed: 1960-07-06
Abstract: A process for resist-colouration of cellulose textile fabrics comprises applying locally to one surface of the fabric a thickened printing paste which contains (a) a nitrogenous resin precondensate, (b) a curing agent and either (c) a reactive dyestuff or (d) a dyestuff which contains one or more isothiouronium salt groups attached to the nucleus through a methylene group thereafter heating to cure the resin and thereafter applying to the same surface of the fabric by, for example, "nip-padding" an oxidation, vat, solubilised vat, "onium" or preferably an azoic dyestuff.  Alternatively more than one coloured or white resist may be applied.  Many precondensates (a) are specified including dimethylol-melamine and 1, 3-dimethylol-4, 5-dihydroxy-2-imidazolidone; also specified are many curing agents (b) including ammonium nitrate and diethanolamine hydrochloride.  Normal thickening agents may be used preferably carragheen moss extract and other usual additives may be included. The reactive dye (c) may be of the anthraquinone, nitro, phthalocyanine or azo series, the preferred reactive group being the dichloro-s-triazine group.  Suitable onium dyes (d) are described in Specifications 576,270, 587,634 and 613,980.  According to the type of dye used for the ground shade superior resists may be obtained by adding citric, tataric or glutaric acids or a mixture of acetic acid and sodium acetate to the resist paste.  Examples of resist-colouration are given. Specifications 209,723, 781,930, 785,120, 785,222, 826,405, 826,689, 838,311, 838,335, 850,599, 859,989 and 939,243 also are referred to.

Title: Improvements in or relating to control systems for electric motors
Inventor: FRIEDLANDER ERICH SIEGFRIED
IPC: B66B1/12
Filed: 1955-08-16
Abstract: 803,224. Rectifying. GENERAL ELECTRIC CO., Ltd. Aug. 7, 1956 [Aug. 16, 1955], No. 23627/55. Class 38 (2). [Also in Group XXXVII] A hand-lever 1, which selects a signal voltage across resistor 8 for feeding into the speed control circuit of a winder motor, is mechanically coupled to the rotor 2 of a three-phase induction regulator 3 having its stator 4 connected to supply 5. The rotor winding is connected across two supply lines through saturable reactor 6 and rectifier 7 and its output voltage is opposed by the line voltage applied to one of the stator phases. In this manner, zero output voltage is obtained for a given angular position of the rotor 2, and a substantially linear rise for angular displacement in either direction from the zero position. Such displacement operates contactors for determining the direction of rotation of the winder motor, and, initially, the impedance of the saturable reactor 6 is large whereby only small signal voltages are derived from the rectifier 7 for application to the resistor 8. Thus, at low speeds, only small changes in the motor speed are obtained for relatively large movements of the hand lever 1. During the later rotation of the rotor 2, the reactor 6 becomes saturated and its impedance approaches zero. Relatively small movements of the hand lever, therefore, produce large changes in the signal voltage at or near maximum speed. The saturable reactor may have an adjustable air gap for varying the relationship between the angular rotation of the rotor 2 and the speed of the motor. The reactor coil may be tapped.

Title: Methods and apparatus for use in electrolytic machining
IPC: B23H3/10
Filed: 1962-06-19
Abstract: <PICT:0970436/C6-C7/1> In the electrolytic machining of metals using a high flow rate of electrolyte and high current density between the workpiece and electrode, the electrolyte is regenerated and freed from dissolved metals by plating these out in an electrolytic cell in circuit with the electrolyte supply and withdrawal flow line. Insoluble materials may also be filtered off, or centrifuged. A suitable electrolyte, e.g. potassium chloride and nitrate with Rochelle salt and potassium citrate as complexing agent, is fed from a tank 26 by a pump 24 to the gap between the workpiece W and electrode 10, from which it flows down a pipe 29 to a plating-out cell 28, and then returns to the storage tank 26.  The plating-out cell has mounted therein anodes alternating with cathodes of relatively large area compared with the workpiece/tool and by bringing the plating cell in the same electrical supply circuit as the electro-machining unit, the current supply to the latter is maintained constant.  Voltage regulators and spacing of the anodes and cathodes in the plating cell also maintain this constant current. The cathodes may be circular rotating discs bearing against bar scrapers to remove the deposits.  The graphite anodes may have a corrugated surface.  Acid may be fed in from a tank 56, and flow is governed by a pH probe 53. Similarly the regenerated electrolyte flowing into the storage tank 26 is rendered neutral by addition of alkali also controlled by a pH probe.  The solid deposited metal residues which may contain Fe, Cu, and Ni are removed as sludge in a centrifuge 66.  U.S.A. Specification 3,058,895 is referred to.
