Title: The production of artificial filaments by melt-spinning
Inventor: THOMPSON ALFRED BROWNBRIDGE
IPC: D01D5/08
Filed: 1955-10-26
Abstract: Molten synthetic linear polymers are extruded through a spinneret and the filaments obtained are passed through a hot liquid whereby they are subjected to increased tension and attenuated and given a degree of molecular orientation such that further stretching is not required, the treatment being effected prior to winding or forwarding to the next operation and no tension being applied to the filaments between the spinneret face and that part of the filament path where solidification takes place.  The filaments are preferably pulled unsupported through the liquid bath, which may be water or a high-boiling liquid having no deleterious effect on the filaments and is preferably maintained at a temperature above the second order transition temperature of the polymeric material.  The liquid level should preferably be positioned so that substantial quenching of the filaments does not occur and so that the filaments enter the liquid without being heated or cooled.  If the hot liquid is in a horizontal container waves on the surface of the liquid may be suppressed by providing a broken-up surface, e.g. glass spheres or corrugations, on the bottom of the liquid container.  The filaments may be wound on a bobbin rotating below a surface speed of 3,000 yards per minute or forwarded by a wheel, roll or fluid stream for further processing, e.g. heating, relaxing, crimping or cutting, excess liquid carried by the filaments being blown off with a rapid transverse fluid stream, e.g. air, or by centrifugal force produced by passing the filaments, with a substantial change in direction of their path, over small idler rolls.  The filaments may be passed through another heating zone, e.g. a flat electrically heated hot-plate or oven fitted with radiant heaters, at a temperature higher than that of the hot liquid and at least 60 DEG  C. below the melting-point of the filaments, after leaving the liquid bath and before winding up or forwarding. Suitable synthetic linear polymers are polyethylene terephthalate, containing if desired, some polyethylene isophthalate, polytetramethylene terephthalate and polyamides.

Title: Improvements in or relating to transistor gating circuit arrangements
Inventor: HART BRYAN LEONARD
IPC: H03K17/68
Filed: 1958-09-26
Abstract: 861,263. Transistor gating circuits. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. June 1, 1959 [Sept. 26, 1958], No. 30834/58. Class 40 (6). In a transistor gating circuit in which the gating signal is applied to the base and the waveform to be gated is applied to, and also an output taken from, either the collector or emitter, the collector and emitter, the collector and emitter are clamped to each other when the gate is closed and the transistor is cut off when the gate is open so that in this condition the output electrode follows the voltage of the signal to be gated and no " pedestal " is produced in the output from the gating signal. The Figure shows a gate using a PNP transistor 5, the signal to be gated being applied at input terminal 1 to the collector electrode from which also the output is derived at terminal 12. The transistor is switched on and off by the gating signal applied from terminal 9 to its base. In the gate closed condition the gating voltage at 9 is negative with respect to the emitter and the transistor conducts and is bottomed so that the collector potential is close to that of the emitter and is effectively clamped to it, the signal output at terminal 12 being negligible. In the gate open condition the gating signal at 9 is positive with respect to the emitter the transistor is cut off and no collector current flows. The collector is thus no longer clamped to the emitter since the collector-emitter impedance is high. Provided that the voltage at terminal 9 is large compared with that from terminal 1 the signal will pass through to output terminal 12. Any " pedestal " is eliminated because in the absence of an input signal at 1 the output at 12 is at a voltage determined by the source 8 whether the gate is open or closed. The signal to be gated may be applied to the emitter and the gating signal to the base, Fig. 3 (not shown). The position of various circuit elements may be transposed. Figs. 4-7 (not shown), the gate functioning in the manner described in connection with Fig. 2.

Title: Improved method of and apparatus for the separation of particles
IPC: B21C23/00
Filed: 1948-11-29
Abstract: 668,628. Centrifugal machines ; washing granular materials. TEDMAN, D. June 10, 1949 [Nov. 29, 1948], No. 30948/48. Classes 23 and 82(ii) Solid particles of different specific gravities or sizes are separated by centrifugal action by introducing a fluid containing such particles tangentially into a helical space confined both circumferentially and axially and communicating with a central axial space having one or more axial outlets, causing the suspension to flow along said helical space to develop forces for separating the particles both axially and radially, utilizing the radial force to drive the particles towards the periphery of the helical space, continuously removing the particles of high specific gravity or large size from the helical space, and utilizing the axial force to remove the particles of relatively low specific gravity or of relatively small size on entering said central axial space. The separating apparatus comprises annular tubular members 7, 8, joined by a tubular helix 9, each turn of which has a circumferential opening on the inner face. Inlet tubes 16-23, 25, delivering tangentially, are sealed into the convolutions of the helix and a similar tube 24 in the members 7. Oppositely disposed tubes are constricted as at 28. The suspension is forced into the helix through some of the tubes 16-23, near its centre, plain water being forced through the other tubes, the fluid pressure increasing progressively from one end to the other. Alternatively, the suspension may be fed through the tubes 22, 23 and water through 16, 17, 24 and 25 or through 16-21 and 24, 25. Heavier material is discharged at one end, lighter at the other, or heavier material may be discharged through 26. Instead of using a suspension in a liquid, the materials to be sparated may be forced into the apparatus as a dry powder in an air-stream.

Title: Improvements in or relating to bottles or the like and closures therefor
IPC: B65D41/34
Filed: 1937-11-11
Abstract: 497,388. Closures for bottles. CHERRY-BURRELL CORPORATION. Nov. 11, 1937, No. 30996. Convention date, Nov. 12, 1936. [Class 125 (iii)] A bottle 10 or other receptacle is sealed by a pliable skirted cap 20 of metal foil moulded on the receptacle to engage parts which secure the cap but permit its intentional removal with an indicating mutilation. The bottle has a lip 11 with an external screw - thread 12 having a flat underface 13 and a bevelled or rounded upper face 14. A cross groove or depression 16 is formed near the lower end of the thread, and the face 15 of this groove is deep and substantially radial to the bottle neck while the opposite face 17 is inclined. The cap 20, which may be of aluminium foil, is caused by pressure to conform to the contour of the bottle lip. The cap is drawn tightly against the top edge of the lip 11 to form a seal, and part of the foil enters the groove 16. This locks the cap against accidental removal, but the application of a turning force tears that part and removes the cap without deforming the screw-thread. The tear 30 serves as an indication that the bottle has been opened, but the cap can be used again as a seal. The thread may have more than one cross groove, and more than one thread may be used. The bottle may have a circumferential bead just below the threaded lip 11.
