Patent GB-869092-A (GB)
Title: Improvements in and relating to the production of regenerated protein fibres
Inventor: WALKER WILLIAM
IPC: D01F4/00
Filed: 1958-07-21
Abstract: In making regenerated protein fibres by extruding a solution of the protein into a coagulating bath, the fibres are insolubilized by incorporating sodium zirconyl silicate in the spinning solution or by subjecting the fibres to the action of sodium zirconyl silicate, preferably at 60 DEG -80 DEG C.  The sodium zirconyl silicate may be added to the coagulating bath or to subsequent treatment baths. Instead of sodium zirconyl silicate, a mixture of a zirconyl salt and sodium silicate may be used.  The fibres may be first hardened in a formaldehyde-salt bath and then treated with sodium zirconyl silicate, the fibres being stretched, if desired, before or during the hardening treatment. Alternatively the fibres may be simultaneously treated with sodium zirconyl silicate and formaldehyde, being stretched, if desired, during this treatment. The treatment liquor containing the sodium zirconyl silicate, with or without formaldehyde, may be sprayed on or otherwise applied to the fibres, which are subsequently stored or heated to effect insolubilization.  In a preferred method, fibres are immersed in a bath containing the sodium zirconyl silicate in solution for a time sufficient to give the desired insolubilizing effect, and are then removed from the bath and washed free from the sodium zirconyl silicate.  The sodium zirconyl silicate bath may contain an acid catalyst, preferably sulphuric acid, and lactic, glycollic, or citric acid as a masking agent, and the fibres, after treatment with the sodium zirconyl silicate, may be treated with an aqueous solution of a cyanate. The Provisional Specification refers to the use of zirconyl salts in general and specifies, in addition to sodium zirconyl silicate, sodium zirconyl sulphate, sodium zirconyl lactate, zirconyl acetate and zirconyl chlorides.  Specifications 565,011, 614,506, 618,925, 690,566, 692,876, 701,645, 741,497, 744,842, 778,257, and 787,588 are referred to.

Abstract: 664,006. Time switches. ORTENBLAD, S. J. V. Sept. 12, 1949. [Oct. 15, 1948] No. 23483/49. Class 38 (v). [Also in Group XXXVIII] A time switch for closing a circuit, e.g. to a wireless set, at a number of predetermined times extending, say, over a week, comprises a clockwork-driven rotary conducting cylinder 5 provided with peripheral grooves 20 in which are inserted at predetermined places conducting balls 21 adapted to engage a 'fixed' contact 22 at the predetermined times. In the form shown the cylinder rotates once every 12 hours and there are fourteen grooves 20 corresponding to the seven days and nights of the week. The contact 22 is mounted on a slide 23 which is moved step by step along a beam 24, each time a pin 29 on the cylinder encounters anyone of a series of oblique vanes 28 on the slide. Thus the contact 22 is moved opposite the next groove 20 every twelve hours. The slide 23 is also provided with a magazine 41 for the contact balls 21, which are inserted into the grooves by means of a plunger 45 actuated by rotating a shaft 48 having an operating knob projecting from the front plate of the apparatus. The balls may later be removed from the cylinder and returned to the magazine by a scraper 65 operated by an external button. The cylinder 5 is driven by a clockwork motor 7 through a friction coupling 13 which allows the cylinder to be rotated by a knob 11 during setting, i.e. while the balls are being inserted into the grooves. At the end of the week, when the slide 23 has reached its extreme position, a pin 29 on the cylinder engages a lever 36 on the slide causing the release of a spring-biased rod 31, carrying a knob, 32, Fig. 9. The leftward movement of the rod 31 carries the slide 23 with it owing to engagement at 31<SP>1</SP> and the slide is thus brought back to its starting position. The knob 32 may then be pressed in to re-strain the spring 34 and reset the rod 31 which is held by a hair-pin latch 33. When at any predetermined time a ball 21 is brought into engagement with the contact 22, a circuit is completed to a relay, which tilts its armature to operate a mercury switch to close the desired circuit. The armature may also carry a hammer which strikes a bell. The armature is later reset by a hand push, or automatically after a predetermined time by a pin 108 on an adjustable ring 107 on the cylinder.

Filed: 1944-11-28
Abstract: 596,584. Controllers. ENGLISH ELECTRIC CO., Ltd., and DOLAN, H. Nov. 28, 1944, No. 23695. [Class 38(iii)] An electric motor controller has a control lever, the movements of which are limited by a gate of " h " or " H " form, and transverse movement of the control lever across the gate effects the operation of a switch which is maintained in an operated condition during longitudinal movements of the control lever in the gate until a return transverse movement is made across the gate. Longitudinal movements of the control lever in slots 11a and 11b effect rotation of a controller drum 14, and transverse motion of the control lever in a slot 11c effects rotation of a drum 22 which is co-axial with the first. The above-mentioned switch is operated by a spring-biased plunger 16 and a tail 10a on the control lever holds the plunger against the fore of the spring during motion of the lever in a slot 11d. In an alternative arrangement, the auxiliary switch is closed by an arm extending the full length of the slot 11d. Movement of the control lever in the slots 11a and 11b provides forward and reverse motor - operation respectively, movement across the slot 11c effecting isolation of the power circuits and substituting braking circuits for the motor, and movement through the slot 11d rotating the drum 14 to afford further braking connections. A gate of " H " form may be provided instead of that shown, to afford alternative braking circuits, in which case the control handle is provided with a double tail. According to the Provisional Specification, the controller may be used in a system wherein an alternating - current motor is braked by the application of direct-current.
