Title: Improvements in or relating to the manufacture of artificial silk
IPC: B65H54/42
Filed: 1936-11-26
Abstract: In a process for the production of artificial silk by the wet spinning process, the silk is wound while still wet, to form a substantially cylindrical package having flat ends, by feeding the thread to a bobbin of wood or synthetic material driven by means of a friction roll having a continuous helical thread guide groove formed therein, the bobbin being provided with a substantially cylindrical core comprising at least two parts capable of being p  detached from one another and removed from the wound bobbin, the core then removed from the wound bobbin and the package subjected to treatment with liquids, e.g. washing under pressure to <PICT:0485933/IV/1> <PICT:0485933/IV/2> remove salt and acid, desulphurization, bleaching or brightening. The thread is preferably wound under slight tension and may have the desired twist imparted to it subsequently, e.g. by the double twist machine described in Specification 369,433, [Group XI].  In an example, thread spun in the bath 11 from nozzle 12 passes around thread guide 13, positively driven draw-off guide 14, thread guide 15, and again roller 14, then under thread guide 16 and under tension to the positively driven friction roller 17 with continuous helical groove 18 which lays it on to bobbin 19 secured on pivoted arm 20 and rotated from roll 17.  The bobbin may consist of three portions 22, 23, 24, Fig. 3, connected by dovetails and grooves.  The assembled bobbin core may be cylindrical or tapering slightly, and certain constituents of the bobbin may also be slightly tapered. Before winding on the core it is preferably covered with fabric or other protective covering.  By the invention, spun packages containing a large weight of thread (200-500 gms. or more) may be produced in one operation.

Patent GB-327094-A (GB)
Abstract: 327,094. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 17, 1928. Fats and fatty oils, oxidized or sulphuretted.- Products resembling linoxyn or oil substitutes for rubber are obtained by heating with oxygen or gases containing free oxygen, or with a vulcanizing agent the mixture of esters produced from glycerol, sorbitol, or other polyhydric alcohol and the unsaturated fatty acids obtained by splitting off water from oxidation products of paraffin hydrocarbons, waxes, or the like. The esters may first be heated with a drier or a metal compound forming a drier with the acids of the esters. Mixtures of the above esters with esters of other unsaturated or hydroxy-carboxylic acids, e.g. cotton oil, rape oil, or linseed oil, or with both may be treated. An inert organic diluent, e.g. petroleum fractions, carbon disulphide, or carbon tetrachloride, may be present. The products may be mixed with linoxyn or other oil rubber substitutes. In an example, 20 kg. of the unsaturated acids obtained by distilling the acid portion, insoluble in petroleum ether, of oxidized paraffin wax are esterified with 2.9 kg. of glycerol while the temperature is raised from 150-200‹ C. 10 kg. of the ester and 0.2 kg. of lead oxide are heated together at 180-200‹ C. for several hours.

Filed: 1937-11-30
Abstract: 491,183. Wireless receiving circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 30, 1937, No. 33093. Convention date, Dec. 3, 1936. [Classes 40 (iii) and 40 (v)] The selectivity of a radio receiver is varied automatically or manually by means of one or more conductors the resistance of which varies with temperature, shunted across the coupling element of a band-pass filter. In its simplest form, Fig. 1 (not shown), the coupling condenser of a two circuit filter is shunted by a 4-volt pocket lamp bulb which glows with a strong signal thus increasing the coupling by virtue of its large increase in resistance. Automatic volume control cannot be used with this arrangement. Alternatively the lamp brightness may be controlled manually or automatically from a separate source, Fig. 2 (not shown). In the preferred arrangement three small lamps G1, G2, G3 are heated in series from source Er which may be controlled manually or in dependence on received signal or interfering signal. Increase of control voltage Er increases the effective capacity of circuits L1, C1, C4 and L2, C2, C5 and increases the inductance of circuit L1, C1, L3, C2, L2 ; the resonance frequencies are thus shifted outwardly to widen the band, without moving the centre frequency.

[Class 38 (iv).] In frequency regulating apparatus in which the actual value of the frequency of a system is compared with a standard frequency the element responsive to the former or that responsive to the latter is influenced in addition in dependence on the difference existing between the actual sum of the alternations in a given period and the standard number. In the form shown the member 6 controls a reversible motor (not shown), operating upon the governor of the prime mover, by intermittent contact with members 4, 5 driven by a motor 3 through an electromagnetic clutch, which is periodically de-energized, at a speed depending upon the frequency. The member 6, so long as the member 9 of a differential gear is stationary, is driven at a standard speed by a clockwork &c. motor 7, but is additionally influenced in the manner set forth by a motor 11 driving the member 9. A member 16 travelling over contacts 18 .. 21 determines the direction of movement of the member 9 and is moved to one side or the other of the position shown by a member 15 between members 13, 24 running at speeds proportional to the actual frequency and to the standard frequency respectively. Resistances 22, 23 arranged as shown cause the degree of additional influence to be dependent on the extent of difference between the actual and standard number of alternations.
