Filed: 1975-09-24
Abstract: 1526754 Numerical machine tool control SIEMENS AG 24 Sept 1975 [25 Sept 1974]  39200/75 Heading G3N A numerical control system for a machine tool can amend the program data e.g. for screw cutting. Data from punched tape 2 passes through de-coder 3 and channel 4 to an intermediate program store 5 with control unit 6. The data is transferred from here in sets through data classifier 7 and distributer 8 to control system 9 which controls the machine tool (not shown). Store 5 can be dispensed with or receive data from manual input unit 11, e.g. decade switches using switch 15, or from a computer. Correction values found in a test run pass to additional store 16, with control unit 17, from manual input 11. Comparator 18 compares the set number (address) of the data in store 5 with the address of the correction data in store 16 so that only the corresponding data is amended in unit 7, Fig. 2 (not shown). The corrected data can then control the tool, or be read out by magnetic or punched tape unit 22, or be indicated by unit 12.

In one form, Fig. 1, the stand 1, cast or injection moulded, has sockets 2 to receive the point sections of tubular point pens, and a space 6 to receive a water-containing tube 11, of porous material, e.g. clay. The water diffuses through the tube into the space surrounding the pen point so that the ink does not dry up. A filling opening 17 may be closed by a member made of transparent material so that the water level can be checked. In one modification (Fig. 2), (not shown) a tubular member corresponding to the tube 11 has an inwardly-extending groove at its upper part into which the pen points extend. According to another modification (Fig. 5), (not shown), the space 6 is filled with porous material, e.g. sponge. In Fig. 3, a square-sectioned water-holding space 8 is provided below the sockets 2, the upper wall 14 of the space 8 having one or more capillary holes 15 through which the water can evaporate into the space around the pen points. The whole stand may be made of porous material (Fig. 5) in which case an upper wall corresponding to the upper wall 14, Fig. 3, is imperforate, and the outside of the stand is covered with insulating material, e.g. varnish so that no moisture escapes through the outer walls. A stand 21, Fig. 6, as described may be hingedly mounted together with a lid 27 on a box 23 by means of a pivot 25. An eccentric on the pivot 25 engages a surface 30 to hold the lid in an open position wherein the pens 26 are at an acute angle to the box base 22. An additional space 32 may be provided in the box to hold a container with refill ink, and closure caps for the pens, and may be closed by a plastics plate slid into grooves.

Title: Improvements in polymerisation catalysts
IPC: C08F4/50
Filed: 1960-11-23
Abstract: a -Olefins are polymerized in presence of a catalyst obtained by refluxing a titanium tetrahalide in an inert solvent with zinc dimethyl or a zinc methyl halide, removing subsequently substantially all of the zinc compounds and converting the "prereduced" titanium compound to an active catalytic species. The removal of zinc compounds may be effected by filtration and/or distillation; irradiation or heating may be used to activate the catalyst. Cyclohexane is the preferred solvent, but others are mentioned.  In the example, ethylene is polymerized using a catalyst prepared from TiCl4 and ZnMe2 and subsequently subjected to ultra-violet radiation. The "prereduced" compounds have the formula TiXmMen (m+n=4) while in the reduced compounds (m+n) is less than 4. Belgian Specifications 533,362, 534,888, 538,782, 540,459, 543,259 and U.S.A. Specification 2,862,917 are referred to.ALSO:Compounds of formula TiXm(CH3)n wherein (m+n) is less than 4 are obtained by irradiating or heating compounds of said formula wherein m+n=4, the latter compounds having been obtained by refluxing TiX4 (X=halogen) in an inert solvent with Zn(CH3)2 or CH3ZnX and removing the zinc compounds by filtration and/or distillation.

Title: Method of producing catalytic electrodes
IPC: H01M4/90
Filed: 1961-11-09
Abstract: A catalytic electrode for electrochemical purposes is produced by pressing a metal powder <PICT:0960479/C6-C7/1> e.g. Ag, Ni, Co, Fe, Ag/Ni or Co/Fe into a cup shaped compact having a recess which is then filled with a catalytic material, covered with a layer of metal powder and finally pressed and sintered.  A gas forming agent to increase the porosity may be added to the metal powder and the catalyst e.g. ammonium carbonate and chloride, phenyl hydracene, sodium azcote.  A metal powder to improve the bending may also be added to the catalyst which may be a powder or a pressed preform to fit the recess. As shown in Fig. 2 metal powder 4 is pressed in mould 2 at 10/100 Kgms./sq.cm., the recess is filled with the catalyst 7 via tube 6, a cover layer of metal powder 4 is added and final compaction is effected at 680/1450 Kgms/sq. cm.  Sintering is carried out in H2, N2, A or NH3.  The compact may alternatively be hot pressed.  The catalysts specified are: a mixture of Ce(OH)3 and Ni(OH)2; AgMnO4; MnO2; MnO(OH); Ag, Pt, Pd sponge; Nb, Ta, Ti, Zr, U powder; mixture of Nb or Ta and Ni powder; activated carbon impregnated with AgNO3; Co/Cr spinel; Raney silver; Ni O; a mixture of nickel and beryllium hydroxides; Ce(OH)3.

Abstract: 905,015. Toothed gearing; securing together rotary parts. UNITED SHOE MACHINERY CORPORATION. Dec. 15, 1958 [Dec. 16, 1957], No. 40274/58. Classes 80 (1) and 80 (2). [Also in Group XXXII] An adjustable means circumferentially positioning an element 32 relatively to an element 20 comprises members 22, 21, respectively keyed to the elements 32, 20 and having teeth 37, 30 of equal form and size meshing only at intermittent peripheral regions, the teeth 30 being formed on a resilient, flexible sleeve 28 of the member 21 for deflection into mesh with the teeth 37 by a surrounding rigid ring 40 of non-circular, e.g. elliptical, bore, which ring when rotated relatively to the said sleeve effects a circumferential translatory movement of the meshing regions to obtain a reduced relative rotation of the members 22, 21 as described in Specification 790,171. There is a difference in the number of teeth 37, 30 equal to, or a multiple of, the number of meshing regions. The ring 40 is self-locking. The setting of the ring 40 and the circumferential relation of the members 22, 21 is indicated by graduated scales on the ring 40 and the member 22 which permit adjustment within one-quarter of a minute of arc. The means described may be used for adjustably positioning cams, such as 32 shown, levers, gears, eccentric bushings, rocker arms, bell-cranks, variable-throw cranks and stops, to take up wear, and to adjust gripping or timing elements, stress and pre-loading of springs and torque tubes or bars, particularly torsion bars on an automobile front suspension to correct for spring creep. Oil sealing is effected by a spring ring 46 retaining the members 22, 21 together, and by a flange 44 locating the ring 40. The latter may have spanner flats or, as shown, holes 47. Backlash is minimized by multiple tooth contact in the meshing regions.

The magnetic image may be applied to the document 10 by selectively actuated styli 16, or the document 10 may be in the form of selectable regions of bands (84, Figs. 4-6, not shown). The visual image is fixed at 54, and may be read automatically by an optical or magnetic pick-up device 55. The toner applicator may comprise a non- magnetic drum 34 having an adhesive surface layer to which a thin layer 42 of iron particles adheres, the toner powder 46 being magnetically attracted to the layer 42 by a magnet 48. Excess toner powder is detached by gravity and by a sweeper magnet 50 which also acts to spread the toner powder on the layer 42. A bias magnet 52 reinforces the magnetic fields of the master source document 10.
