Title: Improvements in automatic stopping mechanism for yarn winding machines
Inventor: HOLLIDAY CLIFFORD
IPC: B65H63/036
Filed: 1955-02-22
Abstract: 796,545. Winding machines-stop mechanism. STUBBS, Ltd., J. May 17, 1956 [Feb. 22, 1955], No. 5195/55. Class 120(2) In a yarn winding machine of the type in which the yarn is laid on the yarn package by a rotating drum, a friction disc is mounted on the end of the drum and driven from a friction disc on a driving shaft, the drum being held, when yarn is present, so that the two discs are in driving contact, but, on breakage or absence of the yarn, being released so that the discs move out of contact and a brake is brought into contact with the disc on the drum and at the same time a lever carrying a brake is also released to apply the latter to a mandrel carrying the tube or bobbin on to which the yarn is being wound. In the embodiment shown, the driving drum A is carried in a cradle supported by an arm B<SP>1</SP> pivoted at B<SP>2</SP> and is driven from shaft C through friction discs a and c. The yarn is wound on a tube or bobbin carried by an expanding mandrel D carried by bracket D<SP>2</SP>. A brake pulley d is arranged at the end of the mandrel D and adjacent thereto is a brake pad e carried by an arm E and normally held out of contact with the pulley d by a pivoted quadrant F against the action of a spring. A brake shoe g adapted to engage the friction disc a is carried on an arm G pivoted at G<SP>1</SP>. The yarn is fed via a detector wire (not shown) and should the yarn break the detector releases the setting-on-lever H<SP>1</SP> which will rise under the action of spring H<SP>2</SP> causing the arms B<SP>1</SP> and G to pivot and raise the drum A away from the shaft C and towards the brake shoe g and the latter to be moved in the opposite direction towards the disc a. The spring H<SP>2</SP> also pivots the quadrant F which causes the brake member e to engage the pulley d and brake the mandrel D. Provision is made to release the brake on the package to allow for "piecing" and also to allow the mandrel D to be moved into a position for doffing.

Title: Improvements in or relating to friction clutches or couplings
IPC: F16D13/75
Filed: 1950-03-02
Abstract: 694,106. Clutches. BINDER, R. March 2, 1950, No. 5252/50. Class 80 (ii). In a friction clutch in which the coupling pressure is transmitted from a central spring, through levers 2 the wear on the friction surfaces is automatically adjusted by means of oneway locking devices 4, 5 between the pressure plate 3 and the operating levers 2 and further locking devices 9, 10 between the plate 3 and the casing 6. When the clutch is engaged the wedges 5 acted upon by springs 8 lock the members 4 to the plate 3 so that the spring pressure is applied to the plate and bolts 9 secured to the plate move frictionally through conical wedge members 10 retained by nuts 11. On disengagement the locking devices 4, 5 are freed and the plate 3 moves back under the action of springs 32 until the conical wedge members 10 engage the casing and prevent further movement. The locking devices 4, 5 and 9, 10 take up a different position relative to the plate 3 on any wear of the friction surfaces occurring. Modified arrangements utilise locking ring devices acting upon bolts connected to the operating levers or the pressure plate of the clutch and serving to take up any wear developed in a similar manner.

Abstract: 1491746 Sputter etching PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Feb 1975 [12 Feb 1974] 5303/75 Heading B3V [Also in Division B6] In a method of making a pattern in one or more layers 3 on a substrate 1 by sputter etching using a photoresist mask 5 covering an intermediate layer 4 which is selectively etched away after sputter etching so as to remove the photoresist mask 5, the intermediate layer 4 consists of metal having a thickness of less than 0À5 Ám which can be removed by sputter etching at a rate which is at least half, and preferably not more than twice, the etching rate of the underlying layer or the average etching rate (as defined) of a plurality of layers. In the manufacture of a semi-conductor device, a silicon dioxide insulation layer 2 on a silicon substrate 1 is first covered by an aluminium layer 3 having a thickness of at least 0À5 Ám. The aluminium layer 3 is itself coated with an intermediate layer 4 of molybdenum and a photoresist layer from which a mask 5 is formed, Fig. 1. The exposed parts of the molybdenum layer 4 may be etched away before the assembly is sputter etched in an argon gas discharge. The portions of the aluminium layer 3 not covered by the mask 5 need not be completely removed by sputter etching, the remaining portions 8 being subsequently removed by etching in phosphoric acid. Finally, the molybdenum layer 4 is removed by etching in nitric acid whereby the photoresist mask 5 is also removed so as to leave aluminium conductor strips 7 spaced apart by no more than 2 Ám on the silicon dioxide layer 2. The intermediate layer 4 may alternatively be of aluminium and the layer 3 to be etched of molybdenum.

Title: Process for bleaching textile materials
IPC: D06L4/30
Filed: 1958-02-20
Abstract: Textile materials, especially of cotton, are impregnated with sodium chlorite and then treated in a closed space with steam in the presence of a volatile reducing agent.  The material may be treated with a chlorite solution acidified with formic or acetic acid and then introduced into a chamber into which steam and hydrogen sulphide are introduced simultaneously at temperatures of 140 DEG  to 212 DEG F.  Sulphur formed during the reaction is discharged from the reaction chamber together with the material, from which it may be removed by washing.  In an alternative procedure, the material, impregnated with a neutral solution of chlorite, is placed in a chamber into which steam and an aqueous solution of formaldehyde are introduced, the formaldehyde oxidizing to formic acid to produce acidic conditions.  The reaction chamber may be additionally heated by steam tubes.  After the treatment the cloth may be washed in successive baths at 203 DEG , 158 DEG  F., and room temperature, and dried.  An apparatus is described in which the process is effected continuously.

Abstract: 925,233. Tube driving rams. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 23, 1960 [Feb. 24, 1959], No. 6278/59. Class 85. A tubular ram for driving tubing through soil has self-releasable jaws to grip the tubing on the forward stroke and release it on the return stroke. The ram 1, Figs. 1 and 13, is integral with its hydraulic cylinder 2 formed between concentric cylinders 3, 4 united at their forward ends by the ram head structure 5 comprising coacting screw-threads at 7 on the cylinders 3, 4 and a self-acting chuck unit comprising a thrust ring 8, jaw ring 9, jaws 10 and front end cap 11. The jaw ring 9 has inwardly inclined grooves 40, Figs. 3, 4, each constituting a seating for a complementary taper surface on the backs of jaws 10 which have forward facing teeth 41 which are also angled to impart a twisting action to the tube. The jaw is supported midway along its length by a cross-head 19 having a pair of legs 20 about which the assembly can be tilted. A pair of load-bearing struts 21, Figs. 15, 16, extend rearwards to the back wall of the trench and a pair of forward steadying struts 22, telescopic and spring- loaded serve to preload the struts 21 and clamp the assembly against axial displacement. Three open helical grooves are spaced around the periphery of the cylinder 4, each being engaged by a roller 33 so that a twisting motion is imparted to the jaws 10 on each forward stroke. The return strokes of the ram are effected by the action of four helical tension springs 35 anchored on posts 36, 37, the latter being connected to the thrust ring 8. Oil pressure is fed to the ram cylinder 2 through a drilling 46 in the well of the piston 13, opened at its forward end through the pressure seal 12 and its rearward end communicates with the automatic spool valve 47, Fig. 12. The sleeve 48 has external grooves 50, 51 communicating with pressure inlet and exhaust ports 52, 53 in the valve housing 54, and adjacent one end has a circumferential groove 55 communicating with the closed space 57. Ram transfer ports 63, 64, 65 can be placed in communication with the "ram forward" port 66, the " automatic operation " port 67 or " ram backward " port 68, respectively by rotation of the sleeve 48. The control port 70 is connected to front valve 72 which opens the circuit to exhaust and back valve 73 which opens the circuit to pressure, each valve being temporarily opened by the ram at the front or back limit respectively of its travel, serving to vent or pressurize the space 57. A helical compression spring 74 serves to bias the valve 47, and axial drilling 75 through land 62 communicates with exhaust port 53 through a radial port 76 opening at the relief 78 between lands 61, 62. The ram assembly can be reversed and so can be adapted to withdraw tubing from the soil and so can be used to lay cables.
