Title: Process for spinning artificial threads from antimonial viscose
IPC: D01F2/22
Filed: 1936-11-27
Abstract: Viscose containing an addition of an antimony compound, is spun by a two-stage process in which it is first subjected to dry spinning with stretching and is then coagulated before or during twisting.  A suitable coagulating bath consists of a neutral or alkaline solution of salts, e.g., cold water is saturated first with salt <PICT:0466550/IV/1> and then with sodium carbonate.  The threads are rendered insoluble by heat, for example as by using boiling spinning baths by steaming the spun threads.  By the process the speed of spinning may exceed 500 metres per minute.  In the drawings, the antimonial viscose is spun through orifice 2 and stretched in the air to form fine filaments 3 which are sprayed while on the drum 4 by means of the atomizers 5.  The filaments may be wound up on the drum 4 or may be carried to a bobbin 7.

Title: Improvements in or relating to raceways for or of loose nailing machines
IPC: A43D71/00
Filed: 1931-11-24
Abstract: 392,916. Nailing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. and GOULDBOURN, J., Union Works, Belgrave Road, Leicester. Nov. 24, 1931, No. 32507. [Class 89 (iii).] Relates to means in a loose-nailing machine for preventing jamming of nails in the raceway at the point where nails enter the raceway from the nail supply, particularly such jamming as results from two nails entering the raceway with their points crossed. Adjacent the hollow 9 where nails enter the raceway from the shelf 7, the raceway groove has the cross section shown in Fig. 4. The top of the groove is bounded by very shallow surfaces 23, below which the groove widens considerably. With this construction, should two nails enter the groove with their points crossed, they are able to turn about an axis extending lengthwise of the raceway, and so fall out of the way. At a point below that at which nails enter the raceway, the groove reverts to the customary cross section shown in Fig. 5, in which the sides of the groove are substantially vertical. The invention is shown applied to a double raceway machine. Specifications 1494/93, 4471/03, 6450/05, [all in Class 89, Nails &c.], 9694/09 and 265,298, [both in Class 89 (iii), Nailing &c.], are referred to.

Title: Process for protecting nitrogenous fibre materials against attack by textile pests
IPC: D06M16/00
Filed: 1961-09-12
Abstract: 941,269. Proofing against textile pests; dyeing nitrogenous fibres. CIBA Ltd. Sept. 12, 1961 [Sept. 14, 1960], No. 32766/61. Addition to 930, 429. Headings D1B and D1P. The process of the parent Specification, for dyeing nitrogenous fibres is modified in that the fibres are impregnated with a two -phase aqueous preparation containing in addition to the assistant and wool dyestuff, or instead of the wool dyestuff, a textile protective agent. The textile protective agent has as great an affinity for the fibres as have wool dyestuffs. Preferred agents are known moth-proofing agents which are also effective against insect attack on furs and carpets, and which contain one or more sulphonic acid groups. Suitable compounds are those of the triphenylmethane or diphenyl ether series, the latter type containing chlorine atoms, a urea grouping or a trifluoromethyl group. The assistant is desirably a hydrophilic colloid capable of coacervation e.g. reaction products of higher fatty acids with more than one mole of a hydroxyalkylamine. A preferred assistant is the reaction product of 1 mol cocoanut oil fatty acid with 2 moles of diethanolamine. After impregnation with the twophase aqueous preparation, the fibres are subjected to treatment with moist heat without intermediate drying, e.g. treatment with saturated steam for 2 minutes at 120‹C. The fibres are then washed, and may be subjected to shock treatment in an acid bath. Specified nitrogenous fibres are polyamide fibres, regenerated protein fibres, silk, leather, pelts, and especially wool, if desired, blended with e.g. acetate rayon, polyester or cellulose fibres. In one example, a wool fabric is impregnated with an aqueous preparation containing a moth-proofing agent, an assistant derived from cocoanut fatty acid and diethanolamine, and a 1: 1 chromium complex of an azo dyestuff. The fabric is squeezed to 100% weight increase, treated with saturated steam for 10 minutes, washed in an ammoniacal bath at 60‹C., washed in water and dried to give a moth-proofed, orange fabric.

Title: Improvements in and relating to the manufacture of composite metal bodies
IPC: B23K35/00
Filed: 1934-11-16
Abstract: In making a composite body consisting of a portion of nickel or nickel alloy, or alloy steel welded to an iron or steel backing, the film of oxide is first removed from the face of the first portion and this face is then electroplated with iron while free of such film and prior to welding.  The surface may be first cleaned by grinding, sandblasting or pickling and is then given a final pickling in a non-oxidizing acid such as hydrochloric acid. In one form, a pair of plates of stainless steel containing 18 per cent of chromium and 8 per cent of nickel with an intervening layer of talc and sodium nitrate and with welded edges, are given a preliminary alkali or solvent cleaning, and after rinsing, the plates are placed in hydrochloric acid, preferably a 35-37 per cent solution for five or six minutes until bubbles rise freely from every part.  The plates are then removed, brushed and washed and placed in the acid again for about 15 secs.  While wet they are transferred to the plating bath. The Specification as open to inspection under Sect. 91 describes a modification in which the plates are cleaned by anode pickling for ten minutes in acid of 18 per cent strength and at room temperature with a voltage of 6.  After scrubbing and washing, they are returned to the bath for one minute and then transferred to the plating bath. In a further form, a high-speed steel containing 18 per cent of tungsten is given a preliminary alkali anodic pickle in a bath containing 150 grams of sodium hydroxide and 15 grams of citric acid to the litre and with a current density of 2,7 amperes per square decimeter.  After scrubbing and rinsing, the plate is dipped in hydrochloric acid of 18 per cent strength and then transferred to the plating bath.  This subject-matter does not appear in the Specification as accepted.

Title: Retroviewer
IPC: G02B27/02
Filed: 1973-07-11
Abstract: 1426605 Retroviewer MINNESOTA MINING AND MFG CO 11 July 1973 33143/73 Heading G2J A retro-viewer for verifying a document 20 having a retro-reflective image bearing layer comprises a condenser, e.g. Fresnel lens 14, collecting light from a light source e.g. lamp 12 and a beamsplitter 16 reflecting light from the condenser on to the document on stage 18 and transmitting retro-reflective light from the layer on the document through e.g. transparent plate 22 to an observer, the condenser producing a virtual image of the light source sufficiently large that the observer's line of sight to all parts of a predetermined document area on the stage passes through the retro-image of the virtual image of the light source over a predetermined range of distances along the optical viewing axis, and sufficiently small that the retro-luminance of the retro-reflective layer is high enough to obscure images on the document underlying the layer. Thus when e.g. an identity card carrying information and having verifying legends on a retro-reflective layer is moved through a slot on to the stage, a lamp switch is actuated by the card and the observer sees only the legends, whereas in normal diffuse light, the layer is transparent and only the information on the card is seen.
