When all the nuts are released the ring 1 together with the nuts is lifted away.
Patent GB-392185-A (GB)
Title: Improvements in artificial silk and like products and processes for their manufacture
IPC: D01F2/28
Filed: 1931-11-05
Abstract: Artificial filaments, threads, ribbons, &c. made of cellulose acetate and other organic derivatives of cellulose, are brought into the highly softened condition required for stretching by subjection to one or more softening treatments leading up to a final softening treatment.  By this means deleterious action on the filaments &c. is obviated.  Generally the softening treatment or treatments preceding the final softening treatment will produce a degree of softening that is less, preferably slightly less, than that effected in the latter. Thus, the materials may be subjected to a succession of treatments of progressively increasing strength, although usually two such treatments suffice to bring the materials into a condition for stretching.  The strength of the softening treatments is determined by the nature, quantity, concentration, and temperature of the softening agent, and by the duration of the treatment.  Higher concentrations and higher temperatures may be employed in the treatment preceding the final softening treatment, provided that the duration of the treatment and other conditions are such that deleterious action on the materials does not result.  The solvents and softening agents are conveniently applied in aqueous solution or diluted with appropriate organic liquids; and to such solutions may be added salts, sugars, &c. as described in Specifications 391,158 and 391,480.  The softening treatments may be applied to the materials while travelling or in package form; and similarly the stretching may take place with the materials travelling as described in Specification 323,790, [Class 2 (ii), Cellulose &c.], or in the form of warps as described in Specification 371,461, and it may be applied very gradually or in stages as described in Specification 370,430 with or without subjecting the materials to the whole succession of treatments at each stage.  The process is of particular value in the treatment of high denier filaments, and of materials made of cellulose derivatives of medium and high viscosity.  The stretched materials may have an improved tenacity. Specifications 277,089, 336,217, [both in Class 2 (ii), Cellulose &c.], and 359,971 also are referred to.

Title: Improvements in or relating to insulated electrical conductors
IPC: H01B3/10
Filed: 1934-10-26
Abstract: 447,754. Glass manufacture. BLUMLEIN, A. D., 7, Courtfield Gardens, Ealing, London, and HOLMAN, H. E., 4, Fairway Avenue, Garden City, Yiewsley, Middlesex. Oct. 26, 1934, No. 30817. [Class 56] [See also Group XXXVI] An electrical wire is insulated by surrounding a part of the wire with a glass tube and then evacuating and drawing the tube. The evacuation may take place after drawing and the tube may be re-drawn whilst it is in an evacuated condition. As shown in Fig. 1, the wire 28 to be insulated is contained on a spool 12 in a casing 6 which is connected to a vacuum pump 10 and which has a neck 7 adapted to be closed by a plug 13. A glass tube 14, which is to form the insulation of the wire, passes through the plug 13 into the casing and surrounds a portion of the wire which is fished through the tube. The wire is sealed to the outer end 15 of the tube by heat, and the sealed end, whilst still plastic, is fixed by a clip 16 to lath 17 having a slot which loosely engages a stud 18 on an endless belt 4 which is adapted to be driven by a motor 5 through a clutch mechanism, not shown, housed in a pulley 3 over which the belt passes. The covering of the wire with glass is effected by heating the projecting portion of the tube by a burner 19 until it becomes soft; the burner is then removed and the clutch in the pulley 3 is engaged so that the lath is carried to the right and deposited in a trough 20, during which movement the lath draws out the tube into a fine capillary, having inside it the wire which has unwound from the spool 12. The glass covering is now evacuated by the pump 10 and the sealed end of the covered wire attached to a drum 21, the covering being then re-drawn, whilst evacuated, by slowly rotating the drum and heating the covering locally by a nickel trough 24, Fig. 2, which is heated by a burner 23 and provided with a handle 25 whereby it may be moved slowly by hand along the covered wire. The whole drawing operation may be carried out in a vacuum, in which case the stage of redrawing may be dispensed with. Specification 447,824, [Group XL], is referred to.

Abstract: 1,032,386. Cooling internal combustion engines. MECANO-BUNDY G.m.b.H. Aug. 4, 1964 [Aug. 5, 1963], No. 31118/64. Heading F4U. [Also in Division F2] A thermostat valve, particularly for the cooling system of an internal-combustion engine, comprises an inlet 1 connected to the water jacket, a conduit 2, clamped to the inlet 1, which leads to the radiator, and a by-pass 16 which leads back to the water jacket. A casing 4 is filled with a temperature-sensitive material 4a<SP>1</SP> and volume changes of the latter produce displacement of a plunger 5 relative to the casing 4. This plunger acts on a bridge 3c clamped between inlet 1 and conduit 2. Water from a cold engine returns directly through the by-pass 1b, but as its temperature increases the casing 4 moves downwards against a spring 7 and carries the closure member 6 from its seat 3 to open the conduit 2. Continued expansion causes the end of the casing 4 to move into the passage 1b permitting a sealing ring 13 carried thereon to close the end of this passage. In modifications, the casing 4 has an integral end instead of a separate plate 11. The sealing ring 13 may be of square section.

Title: Improvements in or relating to electrical resistances, heaters and the like
IPC: H05B3/00
Filed: 1931-11-10
Abstract: 392,549. Grid resistances. EXPANDED METAL CO., Ltd., Burwood House, Caxton Street, WILLIAMS, E. T., 5, Meadway Close, Golders Green, both in London, and MELSOM, S. W., 28, Lansdowne Road, West Hartlepool. Nov. 10, 1931, No. 31179. [Class 37.] A resistance element comprises a sheet of metal slitted so that the current path is a zig-zag passing to and fro across the sheet and stiffened at its edges. The metal sheet is slit in the manner shown in Fig. 3 by passing under a punching tool having an angle of movement making about 45‹ with the sheet so that the sheet is formed with a succession of V's both in plan and end elevation. The sheet is then passed through rollers or put under a press so as to press it into one plane. The end portions 1, 2 are left unslitted and may be stamped as hooks &c. 4, 5 to take connecting members. The edges are stiffened by U -section channelling 6, 7, insulating material 8, 9 being inserted between the channelling and the resistance sheet. Holes 10 .. 13 may be formed in the resistance sheet and the channelling is deformed so as to lock into these holes. A number of units may be assembled together by prolonging the U-section carrier clamps and cutting away half of the U so as to leave flat projections, which are then bolted together. A number of elements in series may be constructed from a single piece of metal so as to avoid joints. The connecting pieces are bent so that the elements are in parallel planes, in which position they are held by insulated bolts and spacing collars. Alternatively, as shown in Fig. 10, the elements are formed separately, and the tops and bottoms of the unslitted end portions Y are bent over and welded. Instead of edge channelling, central plates 19, 20 are employed for stiffening. Rods 16 in insulating tubes 17 are passed through holes in the unslitted end portions, the elements being spaced by bent-up members 21, 22 and clamped together by nuts 23. To protect against deformation due to expansion by heat, the units may be bent so that the zigzag path lies in a curved surface. A number of elements as shown in Fig. 3 may be mounted in a box having grooved or corrugated sides, the grooves or corrugations receiving the stiffening members 6, 7. The resistance may be made from stainless steel, silicon iron, &c., or from metals of higher specific resistance such as nickel-chromium alloys. Hot spots at the corners of the zig-zag path may be avoided by making the distance Z, Fig. 3, relatively large. The invention is particularly applicable to motor-starting resistances, but is also applicable to heating resistances. According to the Provisional Specification. the adjacent strips forming the zig-zag path may be bent in opposite directions out of the general plane of the path.

[Class 141.] A brassiÞre particularly for nursing mothers comprises two breast - supporting pockets adapted to be opened separately to expose either breast without removing the garment, is shown in perspective in Fig. 2, and may involve seaming together the sections shown in Figs. 4-11. The-breast sections are in the form of pockets comprising layers of ordinary fabric, waterproof fabric and absorbent material. The outer layers of the breast pockets are made by seaming together sections 11, 12 and 11<1>, 121 so that the seams emanate in each pair from a single point, which results in shaping the pockets with a minimum of seaming. The pockets are seamed together and to back sections 2, 3 and a front section 1. Suitable cuts 6, 7 are used for shaping the back sections, and in a slot in the front section is placed an elastic strip 8. Behind the outer layers of the breast pockets are arranged shaped pieces of netting 20 which cover the seams. A rubberized lining 24, with absorbent material 22 secured thereto, prevents escape of moisture to the outside of the garments, the rubberized material being shaped by folding without cutting. Supporting strips 26 are provided for the attachment of absorbent dressings.
