Title: Method and apparatus for shaping metal workpieces by electrolysis
IPC: B23H3/10
Filed: 1960-03-04
Abstract: A method of removing metal or metalloid material, e.g. tungsten carbide, form a workpiece 90 comprises supplying electrolyte at a pressure of several atmospheres to the space between the work 90 and a cathode 82, and heating the electrolyte, at 78, while it is under pressure and before it escapes from the interspace, to a temperature above the atmospheric boiling point but below the boiling point at the higher pressure, and recirculating the electrolyte. The electrolyte is delivered by a pump 70 from a reservoir 72 to the hollow interior of the cathode 82, a bypass 98 being provided. Valves 80, 100 enable a desired pressure, e.g. 120 p.s.i., which is indicated at 88, to be achieved at the electrode 82, an overflow 94 leading back to the reservoir 72. The electrode 82 is automatically advanced, e.g. as described in Specification 943,101.  The heater 78 is thermostatically controlled. Gases escape from the enclosure 106 or are vented to atmosphere, steam condensing and being returned to the reservoir 72 via the overflow 94.  Cooling coils 102, 104 may be provided. In a modification, the return flow is from the base of the enclosure 106, so that the work is not submerged, and the by-pass 98 leads directly to the reservoir.  Further, an exhaust duct leads from the top of the enclosure 106 through a motor driven blower to a heat exchanger where steam is condensed and from which the condensate is returned to the reservoir.  The electrode 82 may be as described in Specification 943,101.

Title: Preparation of carboxyalkyl polysiloxanes
IPC: C07F7/12
Filed: 1958-03-12
Abstract: Carboxyalkylsiloxanes are made by hydrolysing a cyanoalkylsilane of the formula:- <FORM:0864681/IV (a)/1> where R is an alkyl radical of less than 4 C atoms, m is 0 or 1, n is 2 or 3, m+n being equal to at most 3, and x is an integer of at least 2, in the presence or absence of at least one alkylchlorosilane, in a hydrolysing medium of aqueous HCl of at least 20 weight per cent concentration.  The dual hydrolysis of the chlorine and cyano groups may be effected at 20 DEG to 50 DEG C. with aqueous HCl of 20 to 40% by wt. concentration the water being present in amount of 1 mol for each Si-bonded Cl atom plus 2 mols for each cyano group.  Examples are given of the hydrolysis of (1) cyanoethyltrichlorosilane alone, and with (2) (CH3)3 SiCl, or with (3) (CH3)2SiCl2.  Uses: in making gaskets and electrical conductors; they can be reacted with long-chain alcohols to give esters which can be used as plasticizers for siloxane resins and rubbers and P.V.C. resins; they can also be converted into Cu salts, e.g. by effecting reaction between aqueous HCl, cyanoethyl trichlorosilane and copper nitrate to give copper salts for use as insecticides and for treating materials to render them mildew resistant. Cyanoalkylsilanes as disclosed in French Specification 1,116,726 may be made by reacting (1) an olefinic hydrocarbon having a cyano group attached thereto, e.g. acrylonitrile, methacrylonitrile, allylcyanide, crotylcyanide and a -chloroacrylonitrile, and (2) a silane containing Si-bonded hydrogen, e.g. SiHCl3, CH3H SiCl2 and C2 H5 H Si Cl2, in the presence of a secondary or tertiary amine, or sodium methylate, as disclosed in French Specifications 1,118,495 and 1,118,496.

Title: Improvements in or relating to automatic multiple arc welding methods
IPC: B23K9/18
Filed: 1956-03-14
Abstract: 815,607. Welding by fusion. UNIONMELT, SOC. ANON. FRANCAISE. March 14, 1956 [March 18, 1955], No. 8009/56. Class 83 (4). In automatic multiple arc welding, e.g. flux submerged or gas shielded in which the ratio of the feeding rates of a plurality of electrodes is maintained constant, the feeding rates are varied together in accordance with an arc characteristic of one of the electrodes which is supplied from an independent current source. Seam welding or hard surfacing may be carried out in this way. As shown in Fig. 1, electrodes 1, 2 are fed by a single motor 6, the speed of which is controlled by apparatus 10 responsive to the voltage across the arc of the pilot electrode 2. Separate generators 4, 5 supply direct current of like or opposite polarity to the electrodes 1, 2. Alternatively, one or both of the electrodes may be supplied with alternating current. Thus the electrodes may be connected to the same or different phases of a 3-phase supply. For seam welding the pilot electrode 1 preferably leads one or more controlled electrodes 2a, 2b, Fig. 6. Specification 475,709 is referred to.

Title: Engine-driven hydraulic pump control
IPC: F16H61/46
Filed: 1969-02-14
Abstract: 1,209,412. Hydrostatic transmission control. GENERAL MOTORS CORP. 14 Feb., 1969 [28 Feb., 1968; 22 March, 1968], No. 8131/69. Heading F2D. In a vehicle hydrostatic transmission in which the inclination of the pump swashplate 51 is adjusted manually by a rod 71 moved in opposite directions for forward and reverse, an automatic control is operative to override the manual control if the ratio selected causes engine overload or overspeed. As shown, the swashplate is moved by servomotor 58, 59 controlled by a rotary valve 17 positioned by a lever 47. The rod 71 is operative on the lever 47 through a central pin 79 fast with rod 71 and a rod 68 connected to the lever. The pin 79 is received in a cylinder portion 75 of the rod 68 and is connected thereto by a spring 92. Under normal conditions, movement of rod 78 is transmitted to rod 68 via spring 92 to rotate the spool 48 of valve 17 to adjust the swashplate. A feedback to the sleeve 49 of the valve 17 disconnects the valve from the swashplate when it reaches its selected position. In the event of engine overload as determined by the force exerted by a rod 35 connected to the engine throttle, e.g. accelerator pedal, and acting on one end of a valve spool 31, and governor pressure in line 44 from an engine-driven governor 12 acting in opposition on the spool 31, an overload signal 41 is delivered from valve 16 to either chamber 85 or 86 defined between the pin 79 and cylinder portion 75 of rod 68 to move the rod 68 relative to the rod 71 to downshift the transmission and reduce the overload. Overspeed of the engine, e.g. on downhill coasting is prevented by governor pressure 44 forcing spool 31 up to connect engine-driven pump pressure 15 through the valve 16 to the apply line 45 of vehicle brakes 46. Engine braking on overspeeding may be provided by connecting line 45 to exhaust ports 97, 98 to upshift the transmission. Again, Fig. 3 (not shown), overload line (41<SP>1</SP>) is connected to equal sized chambers (115), (116) to provide equal response times to downshift the transmission in forward and reverse. The overspeed line (45<SP>1</SP>) is connected to the respective chamber (115), (116) on overspeed to upshift the transmission.

Abstract: 165,201. Wise, E. A., and Merton, H. March 22, 1920. Testing balance of rotary apparatus. - Comprises a scale beam device for testing the balance of engine cylinders or other elements about a given plane. The beam B passes through a. standard A<1> projecting upward from the base A and is pivoted on knife - edges B<1> mounted in the standard. One arm of the beam is surrounded by a split ring C, the split being at the top, and the ring being supported from a stirrup D embracing the arm and resting upon it by a knife-edge D<1>. A lever E pivoted to the arm at E' carries a knife-edge E<2> at rightangles to the beam knife-edge. A balance weight B<2> is hung from the opposite arm of the beam from a point at a distance from the fulcrum B' equal to the distance of the knife-edge D'. A vertical pointer B<4> carried by the beam registers with a fixed mark B<5> while an horizontal pointer C<3> carried by the ring C registers with a fixed mark C<4>. Stops A<2> limit the movement of the beam, and stops E<4> limit the movement of the lever E. In practice, the ring is pushed into the cylinder to be balanced by means of a gauge until the knife-edge. D<1> is in the plane in which the centre of gravity is desired to lie. The cylinder and ring are then placed in the beam with the knife-edge D<1> in its notch in the beam. The cylinder is usually too heavy. Weights are added above the weights B<2> until balance is restored. The additional weight represents the weight of metal to be removed from the cylinder. If now the pointer C<4> indicates lack of balance about the knife-edge D', the lever E is pressed and held down by a catch until the axis of the cylinder is parallel with the beam; and the additional weight previously added is now spread out over the beam to balance the beam with the cylinder in the new position. The positions then occupied by the weights represents the positions from which metal should be removed, due consideration being given to the form of the cylinder and to positions along the cylinder at which material can easily be removed. If it is also desired that some particular portion of the cylinder shall be at the bottom when the cylinder is in a given angular position on the balance arm, the weight of the cylinder is lifted off the knife-edge D<1> entirely on to the knife-edge E<2> by depressing the lever E far enough. It can then be seen whether the cylinder hangs as desired.
