Filed: 1919-06-17
Abstract: 140,944. Haddan, A. J. H., (Textile Utilities Corporation). June 17, 1919. Warp machines. - Comprises improvements in the operating and controlling mechanism for the needle-bar whereby the pattern of the laces, nets, fabrics, or cloths being knit can be readily changed, in the pattern control mechanism, and in the means for tensioning the warps. The needle-bar 55 is slidable horizontally on rails 43 and vertically in guides 53. The vertical movement is obtained from a slide-cam 60 on the main shaft 17 which operates a rock-sbaft 21 and lifting-levers 69, the slots 70 of which receive cam-rollers 71 carried by the lower ends of the needle-bar supporting brackets 58<1>. The horizontal movement of the needles is imparted through the guides 53 which are connected to bolsters 44 reciprocated on rails 43 by links 46 and arms 45 on a rock-shaft 19. The shaft 19 is actuated by a crank-arm connected to an eccentric 29 on the shaft 17. The threadguide bars 76 are provided at their upper ends with lugs 77 carrying pins 78 which are horizontally slidable under pattern control in the lower ends of vertically adjustable hangers 75 contained in fixed hanger brackets 73. The bars 76 are maintained against lateral displacement due to undue tension on the warps, by slotted steadier brackets 87 which work on pins 83 adjustably bolted in an arcuate slot 82 of a fixed arched member 81. The bars 76 are shifted longitudinally, according to the kind of work being made, by horizontal slides 97 which are acted on directly by the links 89 of a number of pattern chains.

Title: Improved process of producing magnesium sulphate
IPC: C01F5/12
Filed: 1944-08-14
Abstract: Magnesium sulphate is produced by treating calcined magnesium oxide-containing materials with sulphurous acid containing sulphur trioxide to form a solution of normal magnesium sulphite and sulphate, oxidizing by a gaseous oxidizing agent to the sulphate, and crystallizing.  Suitable magnesium oxide - containing materials are serpentine, magnesite and brucite.  The sulphur dioxide employed may be obtained by roasting pyritic material, enough being used to dissolve all metals and a small amount of the silica present. Oxidation may be effected by the passage of, or spraying the solution into, air or ozonized air.  Manganous sulphate may be present as a catalyst.  Oxidation may be completed by ozone, chlorine or a hypochlorite.  Iron sulphate may be removed as hydroxide from the oxidized solution by the addition of magnesium oxide or original calcine.  Silica and calcium sulphate may be removed by concentration and filtration.  The insoluble matter after treatment with sulphurous acid need not be removed until after precipitation of the ferric hydroxide.  Specifications 597,028, 603,779 and U.S.A.

Abstract: 967,251. Digital data storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 24, 1961 [May 3, 1960], No. 15542/60. Heading G4C. [Also in Division H3] In a storage matrix of groups W1 to W9 of magnetic cores 1, each group being connected in series with a diode D1 to D9 across co-ordinate conductors taken one from each of two sets 3 to 5 and 6 to 8, a group is selected by energizing a pair of conductors, one from each set, and means are provided to apply a biasing potential to all the conductors of one set to prevent the voltage developed across the selected group producing current flow through unselected load circuits (and thus increasing switching time). The groups of cores each store one word and each core is provided with individual readout coils (not shown in Fig. 1). Selection of group W1 is made by closing switches S1 and S4 when a current path exists through conductor 6, diode D1, the winding on group W1, and conductor 3 to ground. A voltage will appear between conductor 6 and ground which could be applied across a number of capacitive shunt paths associated with unselected groups. One such path is through D7, W7, W8, D8, D2 and W2 to ground. To prevent diodes D4 and D7 conducting a bias of -V2 volts, larger than the largest voltage which can appear across a group of cores, is provided by a source 10. The shunt capacitance is then provided only by diodes D4 and D7. Fig. 3 shows how reading and writing pulses may be applied to a selected group of cores by using two column conductors each connecting a group of cores through a diode to the row conductor. The switches are magnetic cores and transistors. To read out group W4 circuit 17 sends transistor T4 conductive and switches core C2 resulting in current through D4a. Bias is provided from source 18. Writing is done by sending T2 conductive and switching core C4 resulting in current D4b. Appropriate half write currents are applied to windings 19 on cores of group W4. The common return conductor 20 may be replaced by a network of return conductors connected to the common junction of each transistor-core pair T2, C2 &c.

Abstract: 351,687. Blasting detonators. GLÍSSL, K. SCHAFFLER-, 138, Lerchanfelderstrasse, Vienna. May 23, 1930, No. 15924. [Class 9 (i).] An electric blasting fuze, of the kind composed of two flat metal conducting strips which are bridged at one end by a high resistance wire and a priming tip, has a binding clip of sheet metal, insulated on one side, for holding the strips together. The conductors are formed from a metal sheet slotted transversely to form strips 3, as shown in Fig. 1. The blinding clips 5, Fig. 9, are formed from lengths cut from a tape and comprise metal strips 51 with insulation strips 5<2>. Each length of the tape is bent first into a channel section form and is then applied to a pair of strips 3 and subsequently bent into the shape shown in Fig. 9. The marginal edge 1 of the conductor sheet is then cut off leaving free ends 8 to the strips 3 which ends are bent over to form hooks in which is held and soldered an incandescent wire 7. The strips 3 may have enlarged ends 4 which are bent to form channels into which the conducting wires are placed and secured when the marginal edge 2 of the sheet has been removed. The ends 8 are provided with an igniting head in known manner. The clip tape and conductor strips in band form are fed automatically to a machine by rollers 23, Fig. 12, and a feeding finger 24 respectively, the latter engaging perforations 6 in the conductor strip band. The tape 5 is led over an anvil 29 and beneath a plunger 25 and two punches 26, 28. The plunger 25, which is forked, first descends and holds the tape, whereupon the punches 26, 28 descend to sever a desired length from the tape and to bend the same into a channel section. This is retained in its position on the anvil 29 when the punches and plunger are raised by means of an arm 10 (not shown), which is advanced between the forked ends of the plunger. The clip is moved into position over the strip 1 by a slide 11, Fig. 14, and is applied thereto by the resilient arms 12 of a plunger 13, Fig. 15. The conductor strip band with the clips applied to the pairs of strips is then fed in succession to a number of dies and is finally led to a die 20, Fig. 18, arranged below a plunger 19 to complete the attachment of the clips to the conducting strips.
