Title: Improvements in the treatment of textile fabrics for imparting anti-shrink properties thereto
Filed: 1948-08-28
Abstract: Textile fabrics composed wholly or in part of regenerated cellulose fibres are rendered resistant to shrinking by treating them in two stages, first with a solution containing a weak organic acid which is substantially insoluble in water and which has one or more hydroxy groups, and ammonia, and then with formaldehyde (5-10 per cent) and antimony lactate or tartrate. Hydroxylamine or an organic amine or amide base may be added to the first bath, in which case the organic hydroxy-acid may be replaced by an organic acid derived from fats or fatty oils and being substantially insoluble in water.  Acids mentioned are ricinoleic, oleic, caproic, lauric and 1 - hydroxy - 2 - naphthoic acids.  Organic amines or amides specified are urea, thiourea, melamine, benzidine and p-phenylenediamine.  From 1.5-2.5 per cent of the organic acid may be used, but when hydroxylamine or an organic amine is present only 0.3-0.6 per cent is necessary.  In one example, morrocain cloth having a warp of 100 per cent cellulose acetate and a weft of 50 per cent cellulose acetate and 50 per cent viscose rayon, is impregnated in a bath containing urea, ricinoleic or 1-hydroxy-2-naphthoic acid and concentrated ammonia, dried and impregnated in a second bath containing antimony lactate and formaldehyde, dried and baked.

Patent GB-583809-A (GB)
Title: Improvements relating to the preparation of iron oxide reagents for the purification of gases
IPC: C10K1/20
Filed: 1943-09-06
Abstract: Iron oxide tablets for the removal of hydrogen sulphide from gases are obtained by the action of a pressure of some hundreds of atmospheres on a powder containing or consisting wholly of iron oxide containing up to 25 per cent. by weight of free moisture, the powder being of such a particle size and moisture content that it is so consolidated into tablets without the use of a material which acts as a binder in the process.  The powder may be obtained by reaction between a soluble ferrous salt and the hydroxide or carbonate of an alkali metal or of an alkaline earth metal, e.g., by mixing two aqueous solutions and drying the resulting precipitate to a suitable moisture content; or by reaction between two solid substances which are sufficiently moistened to initiate the reaction between them. The powder may also be derived from iron oxide produced as a by-product in the chemical industry.  In examples: (1) hydrated iron oxide is obtained by mixing 5 per cent. aqueous solutions of ferrous sulphate and sodium carbonate, the precipitate is dried until its moisture content is 10 per cent. by weight, graded to a suitable size, e.g., 20-mesh, and compressed in an ordinary tabletting machine under 350 atmospheres.  (2) Iron oxide is obtained by mixing dry copperas with dry slaked lime and initiating their reaction by adding about 5 per cent. of water the reagents being agitated to prevent calcium sulphate also formed from exerting any binding action. The product is dried in a steam oven so as to contain about 8 to 12 per cent. of free moisture, graded to 20-mesh and compressed in an ordinary tabletting machine or a hydraulic press under 1,000 atmospheres.  (3) The moisture content of "Lux" (Registered Trade Mark) iron oxide is reduced to 8 to 12 per cent. by drying, the material is graded to 20-mesh and compressed as in (1).  (4) Native bog ore is dried so as to contain about 20 per cent. moisture, graded to 20-mesh and compressed as in (1) or (2). Specifications 507,593 and 567,231 are referred to.

Patent GB-741599-A (GB)
Title: Adhesive bonding of surfaces
Inventor: SAUL WALTER
IPC: C08J5/12
Filed: 1952-06-11
Abstract: A composition which may be used to treat the surface of a polyvinyl chloride based composition prior to bonding it to a rubber surface consists of "Hycar" OR (Registered Trade Mark), "Bakelite" V 1112 (Registered Trade Mark), and acetone. Alternatively, either the "Hycar" OR or the "Bakelite" V 1112 may be replaced by "Vybak" (Registered Trade Mark) resin.ALSO:Adhesion between surfaces of rubber and polyvinyl chloride based compositions is effected by coating the surface of the rubber with an adhesive composition containing a natural or synthetic rubber, a mixed resinate of a strongly electropositive metal and an amphoteric metal and a solvent, coating the surface of the polyvinyl chloride based composition with an adhesive composition containing at least two of the following constituents:-(a) a synthetic rubber containing acrylonitrile, (b) a vinyl copolymer resin, and (c) a thermosetting resin of the phenolformaldehyde type, and a solvent therefor, evaporating the solvent, and pressing the surfaces together when in an activated condition.  Preferably the treated rubber face is activated by heating to a temperature between 50 and 100 DEG  C. and the treated face of the polyvinyl based composition is heated to 130 to 150 DEG C. In an example, the adhesive applied to the rubber consists of whole tyre alkali reclaim, calcium zinc resinate, toluene and petroleum ether, the mixed resinate may, however, be obtained by combining wood rosin with either magnesium, calcium, nickel or cobalt and also zinc, aluminium, manganese or lead.  In the example the second adhesive consists of "Hycar" (Registered Trade Mark) OR, acetone, and "Bakelite" (Registered Trade Mark) resin No. V.1112. Alternatively this adhesive may be either "Hycar" OR or "Bakelite" V 1112 in acetone together with "Vybok" (Registered Trade Mark) resin. The vinyl copolymer is preferably a vinyl chloride-vinyl acetate copolymer and a minor proportion of wood rosin may also be added. The treated sheets are brought together and may be heated, for example, by infra-red heat in a press or in a floating bowl calender.

Title: Improvements in or relating to the control of electrically operated lifts
IPC: B66B1/18
Filed: 1937-02-19
Abstract: 474,089. Electric control systems for lifts. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. Feb. 19, 1937, No. 14684/36. [Class 40 (i)] In a system of control for a plurality of lifts, unanswered calls above a predetermined minimum are adapted to bring additional lifts into service automatically. The system is described with reference to that described in Specification 465,480 wherein groups of similar apparatus are provided for storing the different types of calls, e.g. car, up and down landing and differentiating as to their priority in association with a two-button collector type lift. The leads 55 ..58 are connected to priority relays, and the leads 51 .. 54 to " start " leads in the "up" and "down" landing storage groups. Lead 59 is connected to a contactor control equipment of an additional lift and leads 60, 61 are connected to the holding relay circuits of the storage relays associated with the " up " and " down " landing calls. Relays UT, DT are connected in the leads 60, 61 and are normally biassed against operation by a resistance RA adjusted so that relay UT or DT only operates in response to the operation of more than a predetermined number of storage relays, i.e. more than a predetermined number of calls. A common relay T is biassed against operation by less than a predetermined total number of calls by resistance RB. If the traffic for lift No. 1 is small, relay T remains inoperative and negative battery is withheld from lead 59 to prevent operation of lift No. 2. The conditions under which lift No. 2 is brought into service are (1) that the total calls are above a predetermined minimum for lift No. 1. with calls ahead of the lift and calls behind in the opposite direction of travel exceeding another minimum or (2) that the total calls are above a predetermined minimum and calls exist ahead and behind the lift for the same direction of travel. The latter condition is the worse, since the lift requires two reversals. Relays AR, BL are " direction " relays and close contacts ar2 or bl2 according to the direction of travel of the lift. Assuming lift No. 1 is travelling upwardly and the " down " calls exceed the predetermined minimum, condition (1) produces operation of relays T, DT and the consequent application of battery to lead 59 to start up lift No. 2. Condition (2) causes operation of relays T, BR and lift No. 2 is brought into action in response to a smaller number of unanswered calls owing to the necessity for a second reversal. When the number of calls awaiting attention is reduced below the values necessary to maintain relays UT, DT, T operated, the relays release and lift No. 2 is cut out of service. Similar apparatus is employed if it is desired to extend the facilities to a larger number of lifts. In order to equalize wear between the lifts, manually operated switches may be provided in order to change cyclically the order of operation of the lifts.

Filed: 1963-04-16
Abstract: A capstan feeding device for wire, or other filamentary material is provided with a narrow groove in which longitudinally spaced stretches of the material being fed are held in radially superposed position and the tension in the outer of these stretches prevents slippage of the inner stretch relative to the capstan by pressing the material into form frictional engagement with the groove.  Wire is drawn by capstan 10 (Fig. 1, not shown), from a device 8 such as a wire-drawing die, and passes as an outer stretch 20 round the capstan to a guide pulley 12, returns to the capstan to pass around it as the inner stretch 21, and becomes disengaged finally from the capstan at the point where the outer stretch passes to the guide pulley 12.  The groove is provided with converging side walls (Fig. 3 not shown). The capstan is driven at constant rotational speed through shaft 11 by means not shown, to control the feed rate of the wire.  When used as a pay-out device the wire or filament is fed into engagement with the capstan as the inner stretch (Fig. 4 not shown).  In an alternative embodiment (Figs. 5 and 6 not shown) the grooved capstan remains stationary while the guide pulley moves in a circular path around the capstan.  In this embodiment the wire is continuously laid in the groove as the outer stretch by a further feed pulley which also rotates about the capstan.
