Patent GB-907184-A (GB)
Title: Melt-spinning apparatus
IPC: D01D11/00
Filed: 1961-02-17
Abstract: As shown in Figs. 1 and 3, a melt-spinning apparatus comprises a spinneret 11 through which a molten polymer is extruded downwards along a vertical extrusion line at a predetermined extrusion rate in the form of filaments 12 through a spinning chamber 14 in which the streams of polymer are solidified to form filaments by directing against them a flow of a cooling gas from the compartment 64 through the fine mesh wire screen 30 and the filaments (which may be grouped into two separate bundles 15) pass through two yarn converging guides 16 and are laid by means of the reciprocating traverse guides 17 on the bobbins 18 on which the filaments are collected at a predetermined rate to form packages 20.  Between the filament bundles 15 and the wire screen 30 there is positioned a rotating cylindrical member adapted to catch the filaments coming into contact therewith and to entangle <PICT:0907184/IV(a)/1> <PICT:0907184/IV(a)/2> <PICT:0907184/IV(a)/3> same thereon so that the filaments will be retained thereon and that the filaments will break between the member and the bobbins. The member may be a cylindrical brush 32 mounted on a shaft 34 having a chuck 36 keyed to the output shaft 38 of an electric motor 40.  The peripheral speed of the brush 32 is controlled to be less than the extrusion rate and the collection rate of the filaments.  The cooling gas urged through the screen 30 is directed against the filament bundles 15 with sufficient force to cause the filaments to follow an arcuate path out of contact with the brush 32 in normal operation when filaments of satisfactory denier uniformity are being produced.  When for some reason a reduction of denier occurs in the filaments being formed, they no longer follow the arcuate path and instead descend directly downwards from the spinneret 11, come into engagement with the bristles of the brush 32 and break between the brush and the bobbins 18.  They then spill along the floor of the chamber 14, as shown in Fig. 3, and on to the platform on which the chamber is supported, warning the operator that a reduction in the denier of the filaments has occurred and that this must be remedied.  Means are described for enabling the brush 32 to be easily withdrawn from the chamber 14 and also its position adjusted therein, the motor 40 being mounted so that it can be pivoted upwards and the brush 32 swung out from the chamber 14 through the opening 53 (Fig. 2).  A filament accumulating brush may be positioned so that they are collected on the brush in the event of the filaments billowing outwards further than normal due to an excessive increase in filament denier, the filaments in this case also spilling on the floor of the chamber 14.

Abstract: 1,131,893. Transistor pulse circuits. SINGER CO. 11 Feb., 1966 [15 Feb., 1965], No. 6023/66. Heading H3T. [Also in Division H2] A frequency divider comprising a rectifier circuit 20, Fig. 2, connected in series across a supply 10 and a control circuit 30 which switches the conductive direction of the rectifier circuit 20 in synchronism with the load voltage is characterized in that a change of state is delayed for a predetermined time after the leading edge of a pulse applied to the circuit 30 and occurs at the leading edge of the first pulse after this delay period. With an input f in,  Fig. 6a, the output to the load 18 is as shown in Fig. 6b which may be smoothed by a smoothing circuit 15 to improve the waveform, Figs. 5 f , 5g, 5h (not shown), and the signals fed to the inputs 12, 13, Fig. 4, of control circuit 30 are shown in Fig. 6d. These two inputs are added, clipped by diode 50 and sharpened by a Schmitt circuit 56, 57 to produce a pulse train, Fig. 6f, which is applied to a bi-stable circuit 32 to change its state. Change of state of circuit 32 feeds a pulse to ramp circuit 33 which, after a predetermined time, switches unijunction transistor 87 to produce a reset pulse for the bi-stable circuit 32, Fig. 6; so that the next pulse in the train 6f can re-trigger it. The resulting output from circuit 32 is a pulse train 6j at an odd submultiple of the source frequency f in  which is used to trigger a further bi-stable circuit 34 to produce push pull switching signals 6k, 6m for the SCR's 21, 22 in the rectifier circuit. The output frequency is determined by the delay time of the unit 33, and varies only within a small predetermined range for a large range in input frequencies, Fig. 7 (not shown). In a modification, Fig. 8 (not shown), capable of dividing by an even number the input to the control unit 30 is taken from across the supply 10.

Filed: 1955-03-02
Abstract: 765,280. Colour photography. AGFA AKT.-GES. FUR PHOTOFABRIKATION. March 2, 1955 [March 5, 1954], No. 6189/55. Class 98(2) Yellow styryl dye masking images to correct for unwanted blue absorption of magenta images in photographic layers produced by colour development of magenta couplers having active methylene groups, such as the 5-pyrazolones or cyanacetyl compounds, are made by reacting untransformed coupler with pyrrole, indole or carbazole aldehydes or functional, derivatives thereof such as the anils. Such aldehydes provide masking images whose absorption is more restricted to the blue part of the spectrum than masking images made similarly with aminobenzaldehydes and derivatives thereof. In Example 1 a multilayer film of conventional sensitivity sequence containing from the support (1) 1 - hydroxy - 2 - naphthoylamino - 2<SP>1</SP> - (methylheptadecylamino) - benzene - 5<SP>1</SP> - sulphonic acid as cyan coupler, (2) 1 -(4<SP>1</SP> - phenoxy - 3' - sulphophenyl) - 3 - hepta - decyl - 5 - pyrazolone as magenta coupler, and (3) p-stearylaminobenzoylacetanilide- 3':5'-dicarboxylic acid as yellow coupler is exposed, colour developed, rinsed, bathed in the m-methoxy-anil of #-indole-aldehyde-2-carboxylic acid, bleached, fixed and washed to give negative colour images with the yellow wash in the middle, magenta, layer. In Example 2 the m-dimethyl-amino-anil of N-ethyl-carbazole-3- aldehyde sulphonic acid replaces the anil of Example 1, and Example 3 uses, similarly, the m-hydroxy-anil of a-pyrrole aldehyde. Examples 4, 5 and 6 are for falsecolour materials in which uppermost unsensitized layers with unspecified pyrazolones as magenta colour formers are washed with the m-sulphanil of N-ethylcarbazole-3-aldehyde, a sulphanil of 1- methyl-2-phenyl-indole-3-aldehyde and the m-hydroxyanil of 2-4-diphenyl-pyrrole-5- aldehyde respectively; and Example 7 is for a somewhat false colour duplicate negative printed from black and white separation records in which the p-sulphanil of #-indole aldehyde produces a yellow wash in the magenta coloured layer. Aldehydes as distinct from anils for use in the invention are listed. Specification 651,059 is referred to.
