Title: Improvements relating to the manufacture of artificial silk
IPC: D01D10/04
Filed: 1933-03-02
Abstract: Artificial silk which has been washed free from acid and dried is twisted and wound on to a bobbin of variable diameter, and the wound package of threads, after diminishing the diameter of the bobbin, is irrigated with the after-treatment liquids.  The bobbin is preferably made of elastic material and slit along its longitudinal axis.  The bobbin is expanded by introducing a core of somewhat greater diameter than the normal internal diameter of the bobbin.  The core may be formed of two parts one of which is introduced into each end of the bobbin thus causing the slit to be widened.  The centre of each part of the core carries a pin adapted to rotate in a slot in the twisting machine.  The bobbin may be driven by a rotating shaft against which the bobbin presses by its own weight.  Parts of the core which extend into the bobbin may be conical.  The bobbin may be of aluminium, or other metal coated with lacquer, or of an artificial material reinforced by embedded metal rings or cloth.  The bobbin may be of much larger diameter than is usual.  The core may be of wood, metal or an artificial substance.  The after-treatment and drying may be effected with the lap still on the bobbin of reduced circumference or after removal.  To protect the threads, a permeable or non-permeable textile, felt, rubber, or other covering may be placed over the bobbin before winding on the thread.  If the covering is permeable, it may be employed to protect the threads during the subsequent wet treatments and the ends may be drawn over the wound lap.  It <PICT:0398738/IV/1> <PICT:0398738/IV/2> <PICT:0398738/IV/3> <PICT:0398738/IV/4> may serve to prevent the lap from being soile by solid impurities in the liquids used.  As shown in Fig. 3, an expansible bobbin 1 is expanded by means of core members 3 with pins 4 which rotate in slots in the twisting machine.  As shown in Fig. 5, a covering of tricot-cloth 7 has been placed over the surface of the bobbin 1 before winding on the threads to form the lap 6.  The core member 3 maintains the slit 2 in its open position and keeps the bobbin expanded.  As shown in Fig. 6, the cores have been removed and the bobbin has resumed its reduced diameter as shown by the slit 2. The fabric 7 is wrapped round the thread lap 6.  As shown in Fig. 7, a number of bobbins 1 with their thread laps 6 are placed on rods 9 and sprayed with liquids.  The threads may subsequently be wound on to cops or spools.

Title: Method and apparatus for generating gas from solid fuel
IPC: C10J3/00
Filed: 1950-03-14
Abstract: 682,267. Gas-producers. HUMPHREYS & GLASGOW, Ltd., and WILLIAMS, N. H. Feb. 13 1951 [March 14, 1950], No. 6412/50. Class 55 (i)' In a generator for making producer or water gas from solid fuel containing a proportion of fines, the fuel bed is divided into two parts placed one above the other with a space between them, the lower bed being fed by dislodgement of fuel from the upper bed which is supported partly by a peripheral shelf and partly by a central support. In the form shown, the generator has an upper chamber 12 separated by a throat formed by a peripheral shelf 20 from a lower chamber 15. The upper fuel bed 19 rests in part on the shelf 20 and in part on a central support 21 and is dislodged from shelf 20 to feed the lower bed 18 by inward blasts of steam or air or by mechanical rams or pushers. In operation, the velocity of flow of blast air or of steam in the lower bed is adjusted to be sufficient to gasify the larger lumps of fuel in that bed. Any fines which are blown from the bed are filtered out in the upper bed, the gas velocity in this bed being lower because of its increased crosssectional area so that little or no fuel is carried over into the gas offtake 14. It is stated that the process described in Specification 654,280 can be carried out in this generator.

Part 7 is a terminal box hinged to part 8 and has grooves 7a permitting limited movement to take up manufacturing discrepancies so that element 6 always lies flat on spider 4. Spring clips 5 retain the bezel.

Title: Improvements in protecting devices for gas-or vapour-filled, controlled discharge tubes
IPC: H02H7/127
Filed: 1949-03-10
Abstract: 659,914. Protective arrangements; converting. NAAMLOOZE VENNOOTSCHAP PHILIPS GLOEILAMPENFABRIEKEN. March 10, 1949, No. 6592. Convention date, March 13, 1948. [Classes 38 (ii) and 38 (iv)] Protection against overload or back-firing of a rectifier or other grid-controlled discharge tube 1 is provided by a two-valve D.C.-coupled trigger circuit adapted, under fault conditions, to render effective a blocking potential for the control grid 2 of the tube. Under normal conditions valve 8 of the trigger circuit passes anode current, supplied by a source 15, thereby causing a voltage to be developed across an anode-load resistor 14 opposing that of a blocking voltage 13, so that the A.C. control circuit 11, 12 is effective to fire the tube. The second valve 18 passes little or no anode current. Under fault conditions valve 8 is cutoff by large negative pulses applied to its grid by a current transformer 3, 4 (or condensers 9, 10) through the network 5, 6, 16, so that the voltage across resistor 14 disappears and the tube is blocked by voltage 13. The grid voltage of valve 18 rises simultaneously; this valve, therefore, now conducts, depressing the grid voltage of valve 8, which is thus maintained cut-off. In a modified circuit, both of the anode-load resistors of the valves are connected in series in the grid circuit of the tube. The valves 8, 18 may be in the form of a double triode having a common cathode and heater.

Title: Method of and apparatus for producing tufted product having unsevered and severed loops

Filed: 1959-02-26
Abstract: 873,032. Tufting machines. McCUTCHEN, J. K. Feb. 26, 1959, No. 6678/59. Class 112 A machine for selectively producing severed and unsevered loops in a tufted material, comprises needles 27 which reciprocate to insert loops of yarn 28 in a fabric base 32. When uncut loops are to be formed the bill 40 of a first looper 39 moves clockwise about its rockshaft 34 to enter the loop as the needle is at the bottom of its stroke. As the needle rises a second looper 37 moves anticlockwise about its rockshaft 33, the looper bill 37 passing below the loop, (see Fig. 10) and thus failing to enter it. The first looper then swings back and the fabric is fed to the right carrying with it the unsevered loop. When a severed loop is to be produced the first looper again swings to enter the loop just inserted by the needle, and a cable 47 is pulled downwards either manually or automatically to cause the looper 39 to rock about its pivot 41 on the looper arm 43, the bill 40 descending to pull down the loop so that the bill 37 of the second looper 36 may enter that loop. The looper 39 then swings back, transferring the loop to the second looper 36 where it is cut by a cutter 54 which may be mounted on the second looper. The severed loop then passes away to the right as the fabric is fed prior to the insertion of the next loop. U.S.A. Specification 2,143,678 is referred to.
