Abstract: <PICT:0378022/IV/1> <PICT:0378022/IV/2> <PICT:0378022/IV/3> <PICT:0378022/IV/4> <PICT:0378022/IV/5> Apparatus for the production of artificial filaments by the evaporative method comprises a spinning jet, a spinning chamber surrounding the jet and provided with an aperture for the emergence of the filaments, a guide-roller adapted to engage the filaments proceeding directly to it from the spinning jet and to guide them through the aperture and deflect them towards the winding device, and means for positively rotating the guide roller.  The roller may be arranged near an aperture in a wall or end of the spinning chamber through which the threads are led to a winding or twisting device, or it may be placed near the edge of one wall of an open-ended chamber, or it may be placed at some distance outside the chamber in line with a thread aperture in an end wall of the chamber.  After emerging from the cell the threads may pass over lubricating, moistening, sizing, or other devices before being wound. The threads may be collected in hanks or on reels and may be twisted by cap-spinning devices.  The process is particularly applicable to the spinning of filaments of cellulose acetate or other cellulose ester or ether.  As shown in Figs. 1 and 2, filaments 13 are extruded from a jet 12 in a cell 11 the front wall of which has a thin portion 14 screwed to a heavy frame portion 16 near the bottom edge of the wall.  The frame 16 is in sections which extend over three spinning cells and are attached to every third partition 17 between the cells by lugs and bolts. The filaments 13 pass down the cell 11 and round a roller or shaft 21 carried in bearings 22 and running in an opening 25 in the frame 16 and projecting into the cell, a gap being left beneath the shaft for manipulation of the filaments.  The gaps are normally closed by flaps 27 with notches 29 through which the filaments pass.  The flaps may be hinged or constructed in the form of sliding panels.  Instead of providing notches in the flaps, the shaft may be provided with grooves.  The filaments pass from the positively driven shaft 21 which may produce stretching, over a moistening or lubricating wick 26, round a roller 32 which may also serve to stretch them, and finally to a cap-spinning device 34.  As shown in Fig. 4, a positively driven guide roller 37 is mounted inside the cell 11.  The filaments pass beneath the roller 37 and leave the cell by an opening 41 covered by a flap 42.  As shown in Fig. 5 the positively driven guide roller 37 is disposed below the cell 11.  The filaments pass directly from the jet down the cell and through an orifice 44 to the roller 37 from which they are deflected to a feed roller 32 and cap-spinning device 34.  As shown in Fig. 6 the roller 37 is mounted with its lower edge just below the bottom of an open-ended cell 11, the filaments running round the roller and forward to the feed roller and collecting device.  Specifications 165,519, 198,023, and 304,674, [all in Class 2 (ii), Cellulose &c.], are referred to.

Abstract: 993, 665. Measuring thermal expansion. C. A. PARSONS & CO. Ltd. March 25, 1963 [April 6, 1962], No. 13280/62. Headings G1A and G1D. The coefficient of thermal expansion of a solid body 1, Fig. 1, is determined by suspending it from a torsion spring 3, starting torsional oscillations by means of an exciter 7 and measuring the periodic time of oscillation of the body 1 at two different temperatures so that the variation in radius of gyration of the body can be determined. The body 1, which is located within a furnace 6, has its periodic times of oscillation measured by attaching a plane mirror so as to oscillate therewith, collimating light from a pinhole and directing it on to the mirror and reflecting it therefrom through a small aperture on to a photo-electric device. The resulting pulses are amplified and used to start and stop a crystal controlled electronic timing mechanism. To prevent inaccuracies due to movement of the oscillating mirror 9, Fig. 3, otherwise than the angular movement intended, fixed mirrors 11, 12, 11a, 12a are arranged as shown, so that if, for example, mirror 9 moves to the dotted position the effect at the photo-electric device is unchanged. In a modification, Fig. 4 (not shown), an oscillating prism replaces mirror 9 and the fixed mirrors, a series of reflections taking place at the internal surfaces of the prism.
