Patent GB-371910-A (GB)
Title: Improvements in or relating to textile yarns or threads and the production thereof
IPC: D01H5/36
Filed: 1931-01-01
Abstract: <PICT:0371910/IV/1> Threads of continuous filaments are stretched beyond their elastic limit at intervals along their length, the remaining portions being either unstretched or stretched to a different extent, the whole being subsequently subjected to a shrinking action.  The threads may be passed round a pair of rollers, the second one of which rotates at a higher peripheral speed to cause stretching, means being provided to vary intermittently the length of path followed by the thread between the rollers, so as to render the stretching intermittent.  The means for varying the length of path may comprise reciprocating, oscillating or rotating means actuated at any desired regular or irregular intervals.  The threads may contain different kinds of natural or artificial continuous filaments of like or different deniers.  The strained threads may be doubled with other strained or unstrained threads, one or more of the components having a high degree of twist, or two intermittently strained threads may be doubled and bound together with a low twist thread to produce a composite thread suitable for the production of cr<\>zepe effects in a single box loom.  The threads may be sized during stretching or otherwise, e.g. as described in Specifications 348,589, 352,451, and 357,169, and subsequently scoured or shrunk; in carrying out the shrinking, the treatments described in Specifications 351,999, 352,000, 356,233, and 357,084 may be resorted to, to effect a swelling of the materials of the threads so as to improve the contraction obtainable.  Thread 5 from the spinning cell 6 passes round a roller 7 and round another roller 8 rotating with a higher peripheral speed, thence to a cap-spinning device 9. Intermittent stretching is effected by a vertically moving rod 11 actuated by a cam 12, which deflects the thread from the straight path.  Such an intermittently stretched thread may be doubled with an unstretched thread, e.g. by passing a separate thread 14 from the spinning cell 6 direct to the second roller 8 and cap-spinning device 9.  The unstretched thread may be delivered from a bobbin, or the whole operation may be effected during bobbin to bobbin winding. Specifications 321,762, [Class 2 (ii), Cellulose &c.], 346,354, and 370,040 are also referred to.

Abstract: 104,674. Devers, P. K. March 6, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Arc lamps; low pressure metallic-vapour apparatus.- Tungsten or other refractory electrodes are enclosed in a sealed envelope containing a quantity of vaporizable material 8 and means for vaporizing and ionizing part of this material to facilitate the production of an arc. Mercury, an alloy, or, better, an amalgam of an alkali metal, such as sodium, potassium, or rubidium, may be used. With mercury, a starting pressure of 200 volts is suitable, the working pressure in a 12-ampere circuit being, say, 15 volts. In the presence of an alkali metal, an initial pressure of 75 volts may suffice. An alkaliresisting glass envelope is required in the latter case. Inert gas, such as nitrogen, argon, neon, or krypton, may also be included at a pressure of at least several mm. of mercury: a pressure of 254 mm. is preferred. During burning of the lamp, the gas is displaced by vapour into the space above a constriction 9. The heater shown is a tungsten filament 10 designed to operate at about 2,000‹ C. and arranged just below the electrodes with a spur 11 dipping into the mercury &c. 8. One end of the heater is connected to the supporting-wire of one of the electrodes 2, the other end being attached to a separate leading-in wire 12<1>. A compensator 15, which may be one of a series, supplies current to the arc and heater circuits in parallel. Each circuit includes a solenoid operating a cut-out 26 for the heater; the core of the solenoid 18 in the heater circuit has a lostmotion connexion to the cut-out and is retarded by a dash-pot 24. In a modification, a transformer supplies both currents, and the cut-out disconnects both ends of the heater from the arc circuit. In another modification, independent transformers with primaries in parallel supply the arc and heating circuits. The solenoid in the heater circuit may in some cases be omitted.
