Title: Improvements in or relating to electric switches and thermal cut-outs
IPC: H01H61/08
Filed: 1927-09-13
Abstract: 277,383. GrÚby, E. Sept. 13, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Thermal switches; switches, quick-action.-A device for regulating the temperature of electric irons &c. comprises a contact 37 co-operating with a fixed contact 52 and carried by a wheel 30 oscillated by two bimetallic strips 22, 22<1> or other thermal devices, such as fluid operated pistons. When the iron becomes hot, the strip 22 bends down, lowers a rod 21 and rotates a member 20 about an axis 19<2> and an arm 20<1> on the member 20 engages a spring 34 connected to the wheel 30, the spring 34 becoming stressed and tending to rotate the wheel 30 in a clockwise direction. The strip 22<1> also bends down, lowers a rod 21<1> and rotates a spindle 25 thereby stressing a blade spring 28 arranged between the spindle and the wheel 30 and tending to rotate the wheel 30 in a clockwise direction. The wheel 30 is prevented from rotating under the action of the springs 34, 28 bv a pawl 46 engaging a tooth 42 until the pawl is moved away by the left hand end of the member 20 engaging a pin 48 on the pawl, whereupon the wheel 30 swings round and effects a quick break between the contacts 37, 52. The moment of release is regulated by raising or lowering the pivot 19<2> by rotating an arm 11. The strips 22, 22<1> now cool and the spring 28 is stressed in a direction tending to move the wheel 30 in a counter-clockwise direction. The pawl 46 bearing on the inclines 45, 44 on the wheel 30 serves at first to retard the action and finally to give a quick make. The strength of the spring acting on the pawl 46 may be adjusted by moving a lever 50. Contacts.-The contact 37 is electrically connected to the terminal 40 by means of a crank 39 and connecting bar 38. Indicators.-The position of the switch is indicated by a pointer connected to the wheel 30 and also by a lamp in parallel with the heating circuit which lights up when the switch is closed.

Patent GB-406715-A (GB)
Title: A method of making extremely thin glass-clear cellulose hydrate films or skins
IPC: C08L1/00
Filed: 1933-09-01
Abstract: Thin cellulose hydrate films, having a superficial density of less than 15 gms. per square metre, for example, 10, 8, 6, and even 5 gms. per square metre, are obtained by extruding cuprammonium cellulose solution under pressure through narrow slots of 0.05 mm. to 0.5 mm. width, drawing out to the desired thinness through a coagulating or precipitating bath of dilute caustic soda, passing by means of suitable rotating transport appliances through the necessary after-treatment baths, and if necessary, drying on a system of heated rollers.  The structure of cuprammonium cellulose solution issuing from the extrusion appliance may be led first through an air gap of a few millimetres and then through a stretch of free precipitating bath amounting to several centimetres, after which it is allowed within this bath to run on to a drum of comparatively large diameter (e.g. 1 metre), to which it may be caused to adhere by endless bands, to prevent transverse shrinkage, and passed on to further treatment on subsequent transport appliances.  The coagulated film is preferably allowed to run on to a drum of large diameter at the point of entry into the first acid bath.  In an example, the solution comprises 7.2 per cent of cellulose, 7 per cent of ammonia, and 3.5 per cent of copper and the width of the extrusion slot is 0.15 mm.  The shaped solution passes first through air for 5 mm., and then freely through a 4.5 per cent soda lye for 16 cm. The partially coagulated film is supported on a rotating drum of 1 m. diameter during the remainder of the coagulation treatment, and then passed on to further treatment successively with water, 10 per cent sulphuric acid, water and glycerine.  The total stretch amounts to about 300 per cent, and the rate at which the film leaves the last bath, about 10 m. per minute.

Patent GB-787557-A (GB)
Title: Improvements in the production of artificial filamentary materials
Inventor: BROWN RUSSELL JACQUES
IPC: D01D5/06
Filed: 1953-09-02
Abstract: <PICT:0787557/IV (a)/1> In wet-spinning wherein the filaments are drawn through a tube through which coagulating liquid flows, the speed of the coagulating liquid in the tube over all except the final inch is arranged to lie between the extrusion speed and the draw-off speed of the filaments and to be higher at the output end than at the input end; and to be independent of the friction between the filaments and the liquid.  The rate of flow of the coagulating liquid is controlled by adjusting the rate of supply to the tube, and the increase in speed as it passes through the tube is achieved by reducing the diameter of the tube, in one or more stages, and the transition from a wider to a narrower section may be gradual.  The speed of the coagulating liquid should not exceed the speed of the filaments, except during the final inch or less, where a restricted outlet causes a local rise in speed of the liquid.  The method is stated to reduce the proportion of filament breakages when a high rate of draw-off is used.  As shown, filaments are spun from the jet 3 into a cylindrical vessel 1 containing coagulating liquid which is fed in at 5 and passes up the setting tube 2.  The vessel 1 may have a conical upper portion or may be wholly conical.  The setting tube 2 has a flared lower end which is positioned 1/4 to 4 ins. from the jet face. The tube has a diameter of 0.25-0.8 in. at its lower end, 0.1-0.45 in. at its upper end and a restricted orifice 11.  The filaments are drawn-off and stretched by the godet 16, entrained liquid being removed by pigtail guide 15 and led into the collecting head 12 by inverted funnel 14.  The filaments pass over skew rollers 18 partly immersed in a washing bath and thence over a second godet 20 to a collecting device or to further treatment means.  The invention is of particular value in the manufacture of cellulose acetate by extruding an acetone solution of cellulose acetate into an aqueous solution of diethylene glycol diacetate or of acetone, but it may be used in other wet-spinning processes, e.g. in the spinning of acetic acid solutions of cellulose acetate into aqueous acetic acid containing a high concentration of a salt such as an alkali metal acetate.  Specifications 695,559, 697,967, 787,556, 787,558, 787,559 and 787,561 also are referred to.
Patent GB-645490-A (GB)
Title: Meter for liquids flowing in pipes
IPC: G01F1/20
Filed: 1948-09-02
Abstract: 645,490. Niscosimeters. DYMOTT, E. R. Sept. 2, 1948, No. 24332/47. [Class 106 (ii)] [Also in Group XXIX] In a meter for use with flowing liquids, of the type in which a member is arranged to move within a pipe section against a resisting force, the member by itself, or in conjunction with the pipe, reducing the cross-section available for flow to a value which remains constant at all positions of the member, means being provided for measuring the force exerted on the member caused by flow, the number, length and crosssection of the passages constituting the reduced flow cross-section are made such that in the case of constant viscosity and varying rate of flow, the force on the member is substantially linearly proportional to the rate of flow. If the rate of flow of different liquids remains constant, the meter can be calibrated to measure viscosity. In the form shown in Fig. 1, a piston 6 slides easily in a meter tube 3, of glass or other transparent material, has a number of relatively small bores 7, and is controlled by a tensionspring anchored to the piston by a split pin 8 and to a stirrup 9 carried by a ring 10. The tube 3 is coupled by flexible sleeves 4, 5, e.g. of rubber, between metal tubes 1 and 2, of slightly greater bore, representing a liquid line. The liquid flow is upward and to prevent damage to the spring when the flow-rate is zero, a metal sleeve 11 is provided where shown. To prevent damage to the piston and spring at excessive flow rates, a washer 12 may be placed where shown. The position of the piston on a scale 13 gives the rate of flow. The above form can be used inverted for downward flow, horizontally or inclined when a piston of suitably chosen materials, or a hollow piston, is employed. The passages may be flutes, grooves or channels in the periphery parallel with the axis. The piston may slide on a fixed rod, to provide a shallow peripheral passage. Two or more opposing springs may be used and they may be arranged to balance the weight of the piston. Instead of a spring the piston may be made to raise a chain from a support. The position of the piston in an opaque tube could be communicated by magnetic, electrical or other methods. A remote indication can be given, for example, by having a piston carrying an electrode, which co-operates with another electrode to form a condenser, the whole being enclosed within an earthed electrostatic shield, readings of capacity indicating the rate of flow. Alternatively, the piston could carry a soft iron skirt co-operating with a winding on the outside of the meter tube, inductance readings indicating the rates of flow. In the form shown in Fig. 2, the piston 6 has inclined grooves 14 in its periphery. Due to their inclination the flow tends to rotate the piston and this is resisted by a torsion strip 15 anchored to the ring 10. The strip 15 carries a mirror 16 whereby a beam of light co-operates with a scale, the tube 11 being cut away at 17 for this purpose.
