Title: Improvements in and relating to the treatment of artificial threads, filaments, fibres and the like
Inventor: RAKOWSKI LECH
IPC: D06M13/11
Filed: 1952-02-25
Abstract: High tenacity polythiourea threads are produced by extruding a polythiourea into the form of a thread, treating the thread with an epoxy compound to improve its stability to heat and, before, during or after the treatment with the expoxy compound, stretching the thread at least 50 per cent. at an elevated temperature, i.e. at not less than 45 DEG C.  The threads may then be further heat treated either in the relaxed state or under sufficient tension to prevent relaxation of the thread.  When unstretched thread is treated with a liquid epoxy compound such as epichlorhydrin the temperature of the bath should not exceed 20 DEG C. and temperatures between 0 DEG  and 10 DEG C. are preferred, the treatment time generally exceeding 1 hour and being preferably at least 10 hours.  The thread may be treated by immersion in a solution of the epoxy compound in an inert solvent such as toluene, for example at elevated temperatures in 1/2 -1 hour.  The expoxy compound used may be epichlorhydrin, ethylene oxide, propylene oxide or glycidol.  In an example a hank of a melt-spun polythiourea thread is immersed in epichlorhydrin at 10 DEG C. for 16 hours, removed, allowed to drain, exposed to the air to allow excess epichlorhydrin to evaporate, stretched 200 per cent. in a water bath at 58 DEG C. between two godets, and dried.  In a second example thread treated as above is wound in a former and heated in air at 100 DEG C. for 24 hours.  In a third example the thread treated as in the first example is immersed in the form of a hank for 10 minutes in boiling water and then dried in air.  In a fourth example a polythiourea thread after treatment with a solution of epichlorhydrin in toluene followed by stretching 243 per cent. in water at 70 DEG C., is immersed in boiling water on a metal reel and dried at 100 DEG C.  In a fifth example a polythiourea thread is stretched by 448 per cent. in water at 59 DEG C., dried, wound on to a bobbin, immersed in epichlorhydrin at 14 DEG C. for 16 hours, allowed to dry, heated in boiling water for 5 minutes and dried at 100 DEG C. Data are given in the examples for the shrinkage of thread on immersion in boiling water after the final treatment. Specifications 524,795, 534,699, 660,905 and 686,190 are referred to.

Title: Electrical synchronising and phasing circuit arrangements
IPC: H04N5/073
Filed: 1943-03-25
Abstract: 562,726.. Television; synchronizing circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Radio Corporation of America). March 25, 1943, No. 4864. [Class 40 (iii)] In order to ensure correct synchronism and phase relationship between a television transmitter 1 and another transmitter 3, Fig. 3, the synchronizing generator 11 of one transmitter 3 is used to control the synchronizing generator 75 of the other transmitter 1 through a phase shifting device 45. This ensures that correct synchronism is maintained at the receiver when transmission is switched from one transmitter to another, or when the outputs of the two transmitters are mixed. In the arrangement shown, the output of the transmitter 3 is radiated by an aerial 55 and received by an aerial 57 followed by a receiver detector 59, a direct current inserter 61, a skimmer 63 for separating and limiting the synchronizing signals, a wave shaper 65 to convert the pulses into a sinusoidal wave, a phase splitting network 67 for providing a three-phase sinusoidal output, a phase shifter 45 which may be a Selsyn motor, and a frequency doubler 71 which produces pulses at double the line frequency. When the synchronizing generator 75 of the transmitter 1 is to be controlled by the master synchronizing generator 11 of the transmitter 3, a switch 91 is closed to connect the synchronizing generator 75 to the frequency doubler 71. When it is desired to operate the transmitter 1 independently of the transmitter 3, the switch 91 is opened and a switch 93 is closed to connect the synchronizing generator 75 through a selecting switch 95 to a single phase or a three-phase system 83 or 79 with which are associated phase shifters 81, 77. The control circuits for the synchronizing generator 75, Fig. 4 (not shown), may include a Selsyn motor and a differential biassing circuit such as described in R.C.A. Review, July, 1940, Vol. 5, Part 1, pages 51-68. The change-over switches may be operated by hand or by a valve relay circuit operating automatically when the output of the frequency doubler 71 fails. The output of the transmitter 3 detected by the receiver detector 59 or the output of the transmitter 1 is selected for transmission by a switch 85. More than two transmitters may be connected through a selecting device to the same transmitting system. For example as shown in Fig. 2, two transmitters 1, 5 controlled by the same synchronizing generator 79, and a third transmitter 3 controlled by a synchronizing generator 11 may all be connected to a single selector 13 ; the transmitter 5 may be connected by a phase shifter 37 to the selector 13 connected directly to the transmitter 1 ; the transmitter 3, however, must not be merely connected to the selector 13 through a phase shifter 45, but must be connected to the synchronizing generator of the transmitter 1 in the manner indicated in Fig. 3.

Abstract: 1,260,746. Micro - filters. BRUNSWICK CORP. 29 Jan., 1969 [30 Jan., 1968], No. 5018/69. Heading B1D. Very small solid particles are filtered from a liquid by a filter element (Fig. 1) comprising an integral metal body structure having a pair of spaced apart surfaces 13 and a plurality of substantially rectilinear passages 12 each opening at the surfaces and having a maximum cross section dimension of under 25 microns; the maximum cross section dimension of each passage, at at least one point therealong, being reduced to under 10 microns by material attached to the structure, e.g. particles or a layer of metal or plastics material, e.g. polytetrafluoroethylene, deposited in the passages. The filter elements are formed by constricting a bundle of metal rods 15 (Fig. 7), each sheathed in a tubular metal sheath 16, by drawing the bundle through a die 18 to form a unified composite 19 (free from voids) wherein the sheaths define a matrix body 21 in which filaments 20 are distributed in parallel relationship; the composite 19 is then transverely cut into disc-like elements 23, and these are suitably treated to remove filaments 20 leaving the required filter passages. If the rods 15 are made of nickel-copper alloy and the sheaths 16 are made of stainless steel, the filaments 20 may be removed by immersing the disc elements 23 in nitric acid. The crosssection of the rectilinear passages may be reduced by sintering metal powder therein, or by forming a layer of metal partially across the upstream openings of the passages (Fig. 6, not shown) by electrodeposition.

Abstract: 115,406. Jelley, J., and Jelley, H. May 21, 1917. Saddles.-Composite rubber and fabric tops for cycle and similar saddles have the edges of the one or more fabric layers enclosed, covered, or sheathed in rubber. For this purpose, in making up the rubber and fabric blanks, either or both of the upper and under layers of rubber are cut larger than the intervening layer or layers of fabric, and during the subjection of the blanks to pressure the one or more extending rubber edges are turned or folded over the edges of the fabric. Each blank, consisting of fabric a and rubber b, c, may be placed in a tray d, and the trays are then arranged in a pile for pressure treatment between a pair of plates, such as e, in such a manner that the extending marginal edges c<1> of the rubber are turned over and pressed down into the fabric. The trays may be used as dies to impress a pattern or lettering in the rubber, and they may also have projections which mark the blanks at the points where holes for the locating-pins of the blocking-dies are to be pierced. In some cases, the turning over of the rubber magazines may be effected during the shaping or blocking of the blank. According to the Provisional Specification, the overlapping rubber edges are bound together under pressure to form around the saddle top a solid rubber edge, which can be trimmed and shaped.

The slot width may be the same as the tooth width in both stator and rotor, or the tooth may be slightly narrower than the slot at the outlet. The number of slots on both members is preferably even. If a rotary field is produced in the stator, the speed of the rotor will be given by the formula n = 120 V (Zr -Zs) #P Zs where V is the supply frequency, P the number of poles and Zr and Zs the number of rotor and stator teeth respectively. By providing a winding on the rotor, currents will be generated therein having a frequency V1 = (nf-nr)#120 P where nf and nr are the speeds of the rotary field and the rotor respectively, and the machine functions as a rotary transformer in which the secondary frequency is slightly greater or less than the primary frequency. The two frequencies may be superimposed, e.g. by means of a transformer to produce a very low beat frequency. Single-phase motors may be started by the provision of an auxiliary phase including a condenser. The machine may operate as a high frequency generator.
