Title: Improvements in or relating to collagen threads, filaments and the like and the manufacture thereof
IPC: D01F4/00
Filed: 1947-04-08
Abstract: <PICT:0663032/IV (a)/1> A collagen strand is rendered suitable as a suture material by treatment with a dilute solution of a tanning agent, softening the resulting lightly-tanned strand with water or an aqueous acid solution, stretching the strand and setting the stretch by treating the stretched strand with a relatively more concentrated solution of a tanning agent and/or a coagulating agent.  The tanning agent used in the second treatment may be the same as, or different from, that used in the first treatment.  According to the example, a collagen solution of pH 2 to 4 is extruded through a spinerette 2 into a coagulating bath 3 containing at least 35 per cent ammonium sulphate at a pH 7.8, preferably in the presence of a lubricant, e.g. vegetable oil.  The strands 4 are stretched over the godets 5, spooled on 6 and, if desired, set in the bath 9 containing at least 35 per cent aqueous ammonium sulphate.  The set strands are pre-tanned for 24 hours in a bath 11 containing 0.05 per cent chromic sulphate (as Cr2O3) at pH 4.8, and at least 35 per cent ammonium sulphate, softened in water or dilute acid 12, stretched over godets 13, given a final tanning in a bath 14 containing 2.5 per cent Cr2O3 at pH 3.8 and 10 per cent sodium sulphate, washed in water 15, dried in chamber 16 at 60 DEG  C. and finally wound on spool 19.  Generally 0.01 to 0.50 per cent Cr2O3 may be used in the pre-tanning stage and 1.0 to 10 per cent Cr2O3 in the final tanning stage.  While any conventional tanning agent may be used, formaldehyde, ferric and aluminium salts are preferred in addition to the chromium salts specified above.  Organic coagulants such as water-soluble ketones, alcohols and ethers may be employed but inorganic coagulants such as sodium, magnesium and ammonium sulphates are preferred.  Pre-tanning solutions are substantially saturated with respect to the coagulants but lower concentrations, e.g. 10 per cent by weight, may be used in the final tanning stage.  15 to 25 per cent, preferably 20 per cent, solutions of coagulants are employed in the softening stage.  The strand may be formed by the extrusion of melted collagen.

Title: Improvements in or relating to textile sliver winding machines
IPC: D01G15/62
Filed: 1955-03-31
Abstract: 791,290. Silver winding apparatus. WILBY, G. P. April 3, 1956 [March 31, 1955], No. 9386/55. Class 120(1) A machine in which sliver is wound on to bobbins is provided with an endless flexible member adapted to support bobbins spaced apart along its length and to carry bobbins successively to the winding position on the machine. As shown, sliver to be wound passes beneath rollers 46, 47, Figs. 1, 2 on an oscillating sliver guide 44 to a bobbin resting on a building roller 31. Six bobbins are carried between bearing blocks 29 on chains 24 passing around sprocket wheels 18, 23. Sprockets 18 are mounted on a shaft 17 at the free end of weighting arms 16 pivoted about a shaft 15. Sprockets 23 are carried on brackets 21 slidable on a framework 19 as shaft 17 rises during winding, chains 24 being tensioned by springs 27. Spring- loaded rods 26 apply pressure to weighting arms 16. Roller 31 is driven via gears 33, 34 from a driving pulley 32 freely rotatable on shaft 14. Sliver guide 44 is oscillated by a cam 43 connected to a worm 37 which is loose on shaft 14 and is driven by gearing from roller 31. Worm 37 drives a worm wheel 49 connected by a link 50 and a lever 51 to a lifter rod 53. When the winding on the bobbin being wound is complete, worm wheel 49 has moved rod 53 to a position where it lifts a handle 55 from engagement with a projection 61 on a cam 62 on shaft 15, and thus releasing a fork 57, connected to handle 55 by a rod 56, and allowing a spring 60 to close a clutch 58, 59; shaft 14 is then clutched to pulley 32 and drives, via chains 65, 67, shafts 15 and 17 so that the full bobbin is removed by chains 24 from the winding position and replaced by an empty bobbin. When cam 62 has moved one complete revolution, projection 61 re-engages handle 55 to disengage clutch 58, 59. During the rotation of shaft 15, eccentrics 69, Fig. 5, cause a lever 71 to rock, engagement of an arm 72 with a guide groove 73 causing a cutter blade 77 first to swing away from the path of the full bobbin, and then to move forward to sever the sliver leading to the full bobbin and push the severed end over the fresh bobbin to initiate the new winding. When all six bobbins are full a detector mechanism operates to prevent further operation of the bobbin change mechanism.

Title: Improvements in electric current timing devices
IPC: H03K17/288
Filed: 1943-06-11
Abstract: 566,961. Control systems for resistance welding. HOLDEN & HUNT, Ltd., HOLDEN, R. W., and BASTERFIELD, H. K. June 11, 1943, No. 9397. [Class 38 (iv)] Switching control.-In a current timing device for a spot-welding machine of the kind in which the time of flow of welding current is determined by the time taken to charge a condenser to the striking potential of a neon tube shunting the condenser in series with the winding of a relay adapted to open the welding circuit when the neon tube strikes and discharges the condenser through the relay winding, the discharge current necessary to actuate the relay is reduced by passing through its winding a supplementary steady current. In the system shown, a welding circuit C is controlled by a starting circuit A and a timing circuit B, the three circuits being supplied through a common transformer 4 having three secondary windings. The starting circuit comprises a relay R2 which, upon closing the starting switch 2, is energized from the secondary winding 1 through rectifiers 8<SP>1</SP>. Actuation of this relay closes (1) a switch R2C in the welding circuit, (2) a switch R2E in the starting circuit which renders the relay self-holding, (3) a switch R2D in the timing circuit, and (4) a switch R2A, also in the timing circuit, which causes partial energization-through a resistance 9 and with rectified A.C. from the secondary winding 3-of a timing relay R1. A switch R2B is also opened by the relay R2, thereby removing a short-circuit from a timing condenser 6, which shunts the relay R1 and a neon tube 5 in series. Rectified current from the secondary winding 3 thereupon flows into the condenser 6 through timing resistances, and when the striking voltage of the neon lamp is reached the condenser discharges through the relay R1 to complete its energization. This relay then actuates to open switches R1A, RIB and R1C in the timing, starting and welding circuits, respectively, thus stopping welding current and preparing the system for the next weld. Initial actuation of the relay R1 also closes a switch R1D which then shortcircuits the resistance 9 so as to increase the steady current through the relay and ensure efficient opening of its other associated switches. Specification 551,910 is referred to.

Title: Improvements relating to the control of electric arcs
IPC: H05B7/152
Filed: 1944-05-17
Abstract: 584,007. Automatic control systems. ENGLISH ELECTRIC CO., Ltd., and ENGLISH, R. L. May 17, 1944, No. 9479. [Class 38 (iv)] . Arcs.-In a system for stabilizing an electric arc, a separately excited D.C. motor 31, which moves an electrode 11 to vary the length of the arc, has its armature supplied by a D.C. generator 20 or an exciter therefor, comprising two field windings 21a, 21b connected with two resistances 22 and 23 in a Wheatstone bridge. Two sources of E.M.F. are applied across different diagonals of the bridge, one proportional to arc current through rectifier 15 and the other proportional to arc voltage through rectifier 17. Deviations from a given proportion of arc voltage to arc current will produce a resultant voltage and excite the field windings according to the extent and sense of the deviation. This combined with a fixed winding 24 winch only becomes excited when the windings 21a, 21b are excited, as described in Specification 560,531, rapidly produces an E.M.F. in the generator which drives the motor in the appropriate direction. The generator may be arranged as described in Specification 579,570 to avoid mutual inductance between the winding 24 and windings 21a, 21b. The value of arc current which is to_be maintained for any particular arc voltage can be adjusted by the rheostat 25 or by tap changing the main transformer supplying the arc current and a scale adjustable in accordance with arc voltage may be associated with the rheostat 25. The speed of raising the electrode is made higher than the speed of lowering by means of the rheostat 30 and a blocking rectifier 32 which renders the generator E.M.F. dependent on polarity. Excessive lowering speed before the arc is struck is prevented by a current responsive relay 18 which short-circuits by contacts 18a a resistance 19. High speed when raising the electrode to full height is obtained by rectifier 34 and relay 33 which opens contacts 33a introducing resistance 35 in series with the motor field, when the generator voltage reaches a predetermined limit. Manual control is obtained by opening contactors 40a, 40b, 40c and 40d; the field winding 24 may then be separately excited from the mains 56, the contactors 41, 42 being used. Means for raising the electrode on failure of the A.C. supply are also provided.
