Abstract: 1304731 Triggering thyristors BORGWARNER CORP 17 June 1970 [3 July 1969] 29463/70 Heading H2F [Also in Division H3] A thyristor triggering circuit comprises a capacitor 87 charged via a variable semiconductor device 88 and arranged to trigger a bi-stable circuit 107 when charged to a predetermined voltage, the bi-stable circuit being coupled to the thyristor via a semi-conductor output switch 118 arranged to produce continuous gate drive when conductive and having means 98 for discharging capacitor 87 and thus removing the gate drive. Terminal 46 of the circuit is connected to the gate of the thyristor which may be used as a D.C.-D.C. converter. Alternatively as in Fig. 1 (not shown) three circuits of the type shown may provide trigger pulses to three thyristors which, with three diodes, form a three-phase bridge for controlling a reversible D.C. motor. The firing point is determined by unijunction transistor 100. Line 72 is connected to the A.C. supply via an auxiliary transformer so that the discharge transistor 98 is turned on at the end of each operative half-cycle so as to terminate the triggering pulse. The three triggering circuits may be interconnected so that gate pulses are only supplied when the anode of the appropriate thyristor is positive. Fig. 1 (not shown) also includes a retro-active control circuit 32 for the motor and reversing switches.

Abstract: 323,812. Tyrer, C., and Mahood, G. H. Oct. 13, 1928. Connecting continuously delivered material to the winding-means.-To facilitate the starting operations in twisting artificial silk by means of ring or flyer spindle apparatus, one end of a " starting-thread " 6 of any suitable material is threaded through the traveller or flyer and secured to the bobbin and the other end is then lapped at a suitable point 7a around the material passing from the metier to a waste roller 4 or the godet, and the material simultaneously severed at 7<b>, the spindle being started immediately before these operations to effect an appreciable pull on the material.

Cops, treating; cops. - Cop tubes a are perforated after being wound by points 83, 84 on levers 77, 78 working in slots 81, 82 in a mandrel 63, the levers being forced outwards by conical surfaces 78, 74 on a plunger 70 connected to a piston-rod 69 driven by a piston 68. Compressed air, admitted by a disc valve under the control of a handle 91<1>, is employed to propel the piston. The return of the plunger withdraws the points by the engagement of the parts 71, 72 with the heels of the levers, thus allowing the cop to be withdrawn. The plunger 70 is adjustably. mounted on the rod 69 but is prevented from rotating by a key 76. Dye dropped on the surface of the cop by nozzles is sucked in direct lines through the yarn, so that the cop is dyed in circular sections extending from the centre to the surface.

Patent GB-891651-A (GB)
Title: Transparent polyethylene films and method for production thereof
Inventor: DOYLE ROBERT
IPC: C08L23/02
Filed: 1958-09-18
Abstract: <PICT:0891651/IV (a)/1> A transparent, non-blocking polyethylene film of density at least 0,94 at 20 DEG C. is made by melt extrusion at a temperature less than 325 DEG C., followed by quenching to a temperature in the range of 135 DEG -160 DEG F.  Homopolymers of ethylene may be used, or copolymers with minor proportions of other olefins, e.g. propylene and the butylenes, provided the copolymers have a density of at least 0,94.  The polyethylene preferably has a density from 0,94-0,98, a crystallinity of at least 80%, a melt index according to ASTM D-1238-52T. of at least 0,5, preferably 0,9-25, a thickness from 0,1-10 mils. and a "seethrough rating" (vide Specification) of at least 18 feet.  Preferably the quenching temperature range is from 140 DEG -155 DEG F. and the quench bath is not more than 1/4 inch from the die outlet, but sufficiently spaced therefrom to prevent vaporization of the bath fluid.  Specified quench bath liquids include water, ethylene glycol, polyethylene glycols, e.g. diethylene glycol and/or their lower alkyl ethers.  The extruded film may be drawn prior to quenching to a draw-down ratio in the range 5:1 to 100:1, preferably 20:1-60:1.  Film so made is of lower density than the original polyethylene, and has enhanced permeability to moisture vapour and gases.  The density can be restored to its original value and the permeability to vapours and gases decreased, without adversely affecting the transparency, gloss and sparkle of the polyethylene film, by annealing the quenched film at from 212 DEG -300 DEG F. for from 0,01-30 seconds or more, e.g. in an ethylene glycol bath.  As shown, polyethylene granules from hopper 8 are conveyed through the melt-extruder 3, surrounded with a jacket 4 through which a heat-transfer fluid is passed, to the inner cavity 11 of die 10, heated by a heater 12 and extruded through slot orifice 14 into quench bath 15.  The quench bath is maintained at a uniform and constant temperature by the mixer 17, heater 18 and thermo-regulator 21, 22, 23.  The film passes around idler rolls 24 and 25 and is wound up at roll 26, which may be used to effect stretching of the film if desired.  Annealing may be effected by modifying the apparatus, the film passing over roll 25 into an annealing bath containing an idler roll before passing to wind-up.

Filed: 1927-11-08
Abstract: 305,610. St. Stephens, R. de H., and Climax Rock-Drill & Engineering Works, Ltd. Nov. 8, 1927. Percussive drills.-In apparatus for enlarging the bores of hollow drill steels &c. of the kind comprising a feed plunger working in a cylinder and moved towards the drill whilst the bore is being enlarged by a punch and away therefrom when the punch is being withdrawn the feed plunger has two hammer pistons mounted therein, one for driving the punch and the other for withdrawing it according to the direction of movement of the plunger. The! hollow plunger a mounted in the end plates b of the casing b<1> is divided by a central partition e into two cylinders f, g in which the hammer pistons h, k are fitted. The front anvil l carrying the punch m and the rear anvil n are mounted in end covers o secured together by bolts p. Movement of the valve c in one direction admits air or other pressure fluid into the casing moving the plunger a to the left. At the same time air passes through a passage q in the plunger and through a passage r in the hammer piston h to the rear of the latter moving it forward to drive the punch m into the bore of the drill steel; at the end of its forward movement the air behind the hammer piston h exhausts through the port u and passage q<1> and more live air passes through the passage q and annular groove v and second passage r to the front of the hammer piston h to effect its rearward stroke. Tha advance of the plunger a and reciprocation of the hammer piston h is continued until the enlargement of the drill steel bore is completed, whereupon the valve c is reversed admitting air to the passage w to move the plunger a backwards, air also passing through passage q<2> and passages s in the hammer piston k for reciprocating the latter so as to strike the rear anvil n as the punch is withdrawn.
