Title: Improvements in and relating to the driving mechanism of machines for spinning artificial silk
IPC: B65H67/048
Filed: 1933-05-12
Abstract: 421,273. Bobbin-winding mechanism of artificial silk spinning-machines. BERL, E., Carnegie Institute of Technology, Pittsburg, U.S.A. May 12, 1933, No. 13823. [Class 120 (ii)] In machines for spinning artificial silk a single pair of cones is used for driving the bobbins to ensure a constant winding speed, four clutches 26, 27, 28, 29 being provided and operated so that each cone in turn is the driver by means of a cam 43 on a shaft 58, which at the desired time is rotated through 180‹ and by means of sprocket gearing 62, 64 operates the shaft controlling the bobbin-change gearing. The main shaft 2 is geared by chains 5, 6 with half-shafts 10, 9 of the top and bottom cones, and by a chain 66 with a shaft 68 controlling the gearing for effecting the half-rotations of the shaft 58. The half-shafts 10, 9 respectively carry one half of clutches 27, 28, and corresponding half-shafts 11, 12 respectively carry one half of clutches 26, 29 and are geared by chains 15, 16 with the bobbin-driving shaft 19. The complementary halves of the clutches 26-29 are carried by bushes to which the cones are secured. The half-shafts are moved longitudinally to effect the requisite operation of the clutches by means of levers 38, 39 actuated by coupled levers 40, 41 and the cam 43, diagonally disposed clutches being open and closed. As shown, the drive is from the shaft 2 through chain 6, clutch 28, cones 24, 25, clutch 26 and chain 15 to shaft 19 ; the reverse drive is through chain 5, clutch 27, cones 25, 24, clutch 29 and chain 16 to shaft 19. The belt fork 48 is traversed by means of a spindle 49 rotated for this purpose from the main shaft 2 by gearing 51, 64, 56, carried by a casing 50, which is given a half rotation, as necessary, by a chain 60 from the shaft 58, to reverse the direction of rotation of the shaft 49 and of the travel of the belt, by causing one or other wheel 54, 56 of the train to engage a wheel 57 on the shaft 49. The shaft 68, for controlling the half rotations of the shaft 58, actuates cams 70, 88, coupled by 2: 1 gearing 90, 89, and drives a halfcoupling 76 through a chain 79. The cam 70, in co-operation with a rod 71 and spring 72, closes the coupling 76 and thus effects the driving of a coupling 84 through gearing 81, 82. The coupling 84 is geared to the shaft 58 but is disconnected from the gearing 81, 82 by the cam 88 after half a revolution. Specification 367,370 is referred to.

Title: Improvements in and relating to the production of metal-metal oxide compositions or alloys
IPC: C23C8/10
Filed: 1946-05-09
Abstract: A method of forming a metal-metal oxide composition or alloy suitable for use as an electrical contact material, a bearing or bearing material, a brake lining or a clutch facing which comprises internally oxidizing the oxidizable metal or metals of a metal-metal oxide composition or alloy of which at least one metal has a high diffusion rate for oxygen without forming a stable oxide or oxides and the other metal or metals has or have a high affinity for oxygen and a tendency to form stable oxides, the first-mentioned metal or metals remaining unoxidized and unaffected.  The oxidizable metal or metals may have low-melting points, the unoxodizable metal having a relatively high melting-point, the body being heated to melt the low melting point metal or metals and an agent capable of oxidizing the low melting point metals is dispersed in the body under ambient pressure sufficient to prevent boiling off of the said low melting point metal or metals.  The composition or alloy may be subjected to heat and to an oxidizing agent so as to diffuse the said oxidizing agent through the composition.  The relative distribution of the metals is preferably not affected by the treatment.  The composition may comprise a silver base alloy, e.g., silver-cadmium or silver-lead or an alloy of gold, palladium or platinum group metal and cadmium, lead, thallium or copper or a silver-thorium or silver-beryllium alloy.  In the manufacture of a composition having high secondary emission the invention is applied to a silver base composition containing material consisting of one or more of magnesium, calcium, strontium, barium, thorium, uranium, titanium and zirconium.
