Abstract: 950,758. Feeding and mixing fibres. COTTON, SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. Sept.12,1962 [June 15,1961], No. 21585/61. Headings D1F and D1N. Textile fibres are mixed by repeatedly forming a layer of fibres on a reciprocating carriage 15, while simultaneously removing from the carriage the previously formed layer to form an assembly of superimposed layers on supporting means 17. In one example as the carriage 15 travelling on rails 13 approaches a hopper 10, arms 16 on the approach side of the hopper remove the fibre layer from the carriage on to a conveyer 17 and a new fibre layer is deposited through feed rollers 11,12. Motor 18 which drives the carriage through belt 21, drum 24, and ropes 28, 28<SP>1</SP> is now reversed and the other set of arms 16 is lowered to remove the new fibre layer on to the conveyer 17 which continuously feeds the assembly of layers to spiked rollers 35. Motor 18, rollers 11,12 and each set of arms 16 are controlled by switches actuated during each traverse of the carriage 15. Alternatively the fibres may fall on to stationary supporting means 17, with the assembly of fibres thus formed removed for further mixing by a set of rollers 35. Specification 841,559 is referred to.

Title: Improvements in or relating to the manufacture of strip material
Inventor: SHRIMPTON RONALD HORACE
IPC: B29C48/885
Filed: 1967-05-10
Abstract: 1,214,631. Extruding convoluted strip material. DUNLOP CO. Ltd. 8 May, 1968 [10 May, 1967], No. 21727/67. Heading B5A. [Also in Division B8] An extruded strip having a convoluted portion as at 40, Fig. 12, is made by extruding material, e.g. rubber, through a die orifice having a first part with bevelled leading edges and a second part which is obturated, the rate of flow through the first part thereby being greater than that through the second and the convolutions being formed by the restraining effect of material passing through the second part on that passing through the first part. The die plate of Fig. 4 has an essentially L-shaped orifice with the upstream edges of limb 19 being bevelled and an obturator 22, upstream of limb 20, being adjustable towards and away from limb 20 by rotation of bolts 23. The obturator may be angled to the die plate by rotating one of these bolts more than the other. In a modification, Figs. 8-11 (not shown), for producing the extrudate of Fig. 12, both limbs (31, 32) are bevelled, the former more so than the latter. At the junction of the limbs is an enlarged portion (35), Fig. 10 (not shown), which is masked on its upstream side by a throttle (37) attached to an obturator (36), Figs. 8, 9 (not shown). Throttle (37) is adjusted to produce an unconvoluted step portion 39, Fig. 12, which buttresses both unconvoluted limb 38, produced by material passing through die limb (32), and convoluted limb 40, produced by material passing through die limb (31). Preferred materials are vulcanizable elastomers such as natural rubber and styrene-butadiene copolymers or blends thereof. In the apparatus of Fig. 1, vulcanization takes place in a bath 7, which may contain a mixture of sodium nitrate and sodium nitrite, and the vulcanized product is washed with warm water in a bath 11. Other methods of vulcanization or curing mentioned are heating by use of heated liquids such as glycol, heated gases such as air, infra-red and micro-wave heaters and fluid bed techniques. Other materials mentioned are P.V.C., ethylene vinyl acetate copolymers and polystyrene-polyisoprene block copolymers in the use of all of which bath 7 may be dispensed with. The apparatus is particularly intended for the production of conveyer-belt edging.

Title: Improved screw-cutting attachment for machine tools having reversible working spindles
IPC: B23G1/46
Filed: 1951-09-20
Abstract: 697,061. Screw-cutting attachments. ANGST, F. Sept. 20, 1951 [Sept. 22, 1950], No. 22077/51. Class 83(iii). A screw-cutting attachment for tapping or screwing rotating work has a pair of dogclutch members 28, 32 journalled on a stud 16 screwed into a tool-holder 7 and having a spring 34 tending to press them apart, a set of balls 29 fitted in conical recesses 27 in the toolholder 7 and in the clutch member 28, and spring-loaded balls 37 fitted in the clutch member 32 and engaging a conical part 35 of the stud 16. A pair of rollers 43 are also fitted on the clutch member 32 and slide in a wide recess 44 in the body 1, their forward movement, and therefore the length of thread cut, being limited by an adjustable screwed collar 45. When the tool contacts the rotating work, it is held against rotation by the clutch and by the rollers 43 bearing against one side of the recess 44 in the stationary body but feeds forward according to the pitch of the screw being cut. The tool-holder is initially supported at points 5, 11 but is tapered between these points so that, as it feeds forward, it is only supported at point 11 and by the work, and can oscillate with work which is not running true. During forward feed, the wedging action of the balls 29 in the conical recesses forces the tool-holder and clutch member 28 apart by a clearance a but, when the rollers 43 meet the collar 45, the clutch member 32 is held back while the other member 28 moves forward until it disengages. The tool-holder and member 28 are now freely rotatable and the spring 34 takes up the clearance a so that the two clutch members are definitely separated and cannot engage because of vibration. Since the stud 16 has moved forward with the clutch member 28 relative to the clutch member 32, the balls 37 now ride over grooves 36 in the portion 35, but when the work-spindle is reversed, they rotate the member 32 until the rollers meet the other side of the recess 44, where they move forward into a small cut-out 46 and allow the clutch members to re-engage and again prevent the tool rotating. The screw 41 in the end of the stud 16 holds the member 32 against rearward movement which would render the balls 37 ineffective. By moving the collar 45 so that the cut-out 46 adjoins one or other side of the recess 44, right- or left-hand threads can be cut.

Title: Preparation of esters of hyponitrous acid
Inventor: SEED LESLIE
IPC: C07C203/00
Filed: 1955-08-04
Abstract: Esters of hyponitrous acid are prepared by oxidizing or dehydrogenating an O-ether of hydroxylamine having the formula R-ONH2, in which R is an organic radical, at temperatures below 50 DEG  C.  The oxidation may be carried out with oxidizing agents such as mercuric oxide or other metallic compounds in a higher valency state; halogens, their oxyacids and salts of the latter; inorganic or organic peroxides; persalts; oxygen, alone or in the presence of a carrier; azo compounds or other dehydrogenating agents; nitrous acid and its derivatives; other oxy-acids, their anhydrides or salts. Particularly useful are the halogens and their oxy-salts formed when they react with alkaline or alkaline earth oxides or hydroxides.  The oxidation may be carried out electrolytically or the dehydrogenation may be effected catalytically.  It may be carried out under anhydrous or aqueous conditions, in alkaline, neutral or acid environments with undiluted reagents, or in the presence of an inert medium; in a homogeneous or heterophase system.  It is particularly useful to use an aqueous alkaline medium whereby the hyponitrous esters separate as insoluble oils.  In an example, bromine is added dropwise to an aqueous solution of caustic soda at 0 DEG  C., the mixture is cooled to -10 DEG  C., ethoxylamine is added dropwise and the mixture stirred for an hour at -10 DEG  C., whereby a yellow oil separates; the ethyl hyponitrite is extracted with ether, the extract is washed and then dried over calcium chloride and the ether is evaporated by rapidly drawing air through.  Specification 618,168, [Group IV (a)], is referred to.
