Title: Improvements relating to the treatment of filaments, threads, yarns and like textilematerials
IPC: D06M11/155
Filed: 1931-09-01
Abstract: In the process for conditioning natural or artificial yarns, filaments, tapes, straws, artificial hair or bristles, &c. described in the parent Specification, there is employed as the hygroscopic substance to be applied in an alcoholic medium, the following salts:--Ammonium citrate and acetate; magnesium, calcium, zinc, iron, strontium and other chlorides; nitrates of magnesium, calcium, zinc, iron, cobalt and nickel; ammonium, sodium and potassium formates; sodium and ammonium phosphates; amines and amides and their salts; for example, acetamide and methylamine hydrochloride; and salts of quaternary ammonium compounds.  By this treatment, the yarn &c. is rendered more amenable to weaving, knitting, &c.  The salts or mixtures of them are applied in alcoholic solution or suspension; and as the alcoholic medium there may be used methyl or ethyl alcohol, or their aqueous solutions, or di- and polyhydric alcohols, advantegously containing such an amount of water as their natural hygroscopicity causes them to take up.  These latter media have a softening effect on the yarns &c. particularly in the cause of cellulosic materials and to a less extent those of cellulose acetate, and this softening effect may be enhanced by the addition of softening or swelling agents appropriate to the yarn &c. under treatment.  The application of the hygroscopic substance to the yarns, particularly those of natural silk or those containing cellulose acetate overcomes or reduces electrification troubles. A suitable solution contains 2-10 per cent of magnesium chloride in ethyl alcohol, 40-60 per cent aqueous alcohol, or diethylene glycol. A wetting agent may be added to the treatment liquid, or the yarn &c. may be pretreated with such agent.  In some cases the treatment liquid has lubricating properties; but a lubricant such as an oil or fatty acid may be incorporated in the liquid, or the materials may be separately treated with a lubricant.  The treatment may be applied continuously with the production of cellulose acetate &c. yarns by the dry method; or it may be applied during a winding or twisting operation; and it may be applied continuously with an operation in which the yarn is being used, as for example in a knitting machine, or to the weft yarn as it is being led to the weft-inserting means of looms having stationary weft supplies; or the yarns in hank, bobbin, &c. form may be immersed in the treatment liquid, or such liquid may be forced therethrough; or it may be applied to beams or sectional beams either by immersion of the yarn or by means of liquid-applying rollers, and such operations may be continuous with sizing.  For the application of the liquid, a wick or pad particularly of the form described in parent Specification may be used; or a drip tube or rotatable roller or disc preferably mounted at an angle to the path of the thread &c. may be employed; or the liquid may be applied as a spray.

Title: Improvements in or relating to method and apparatus for crimping shells
IPC: B21D39/04
Filed: 1947-09-10
Abstract: 643,740. Spinning. ATLAS POWDER CO. Sept. 10, 1947, No. 24843. Convention date, Sept. 14, 1946. [Class 83 (iv)] A machine for crimping a number of shells simultaneously has means for holding the shells, a member containing a number of crimping edges each surrounding one shell and means for simultaneously pressing the edges against the shells and moving the member relative thereto through a path similar to the crimping edges. Crimping grooves are formed in the shells 26, Fig. 5, e.g. of blasting caps, held in wells 24 in a body 20 by ridges 67 in holes of a plate 62 through each of which a cap projects, the plate being moved in a spiral path by two variable-throw cranks 58. These are each moved radially of their shaft 30 by a screw 46 which is rotated by bevels 90, 92 from a sleeve 86 loose on the shaft 30 and driven at a slower speed by gearing 88, 82, 78, 41, thus moving the plate 62 in a gradually increasing spiral path. In a modification the screws 46 are each rotated through a small angle at one point in each rotation of the shaft 30 by the lowest pin 50, Fig. 3, of a pinwheel 48 on the screw engaging a fixed pin 52, thus moving the plate in a path comprising a series of gradually increasing and connected circles, Fig. 7. The shafts 30 are driven through gearing 41, 38, Fig. 5, by a handle 34 and after crimping this is turned in the reverse direction to bring the cranks back to their original position. Each hole in the plate may have a number of ridges, e.g. as shown in Fig. 9, to crimp a shell 26 about a plug 94 containing wires 96 or a number of separate plates 102, 104, Fig. 10, may be used. A fixed plate 69, Figs. 3 and 5, or a number of such plates 106, Fig. 10, may be used to support the shell. To reduce still further sliding of the tool on the work the ridge may be carried by an annulus 162, Fig. 11, mounted by a ballbearing 110 to turn freely in the plate 62. The Specification as open to inspection under Sect. 91 comprises also the application to shells having oval or other non-circular section and to machines in which the plate 62 is fixed, the proper relative movement required being obtained by moving the shells to be crimped. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to refrigerating plants
IPC: F25B43/04
Filed: 1931-09-04
Abstract: 387,028. Refrigerating. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 4, 1931, No. 24861. Convention date, Sept. 12, 1930. [Class 29.] Vacuum machines and systems.-Air is removed from a vacuum machine by an ejector operated by refrigerant vapour. In an apparatus comprising a compressor 1, condenser 2 and evaporator 4, a mixture of air and refrigerant vapour is withdrawn from the condenser 2 through the pipe 10 by the ejector 9 and discharged, together with the operating vapour for the jet, through a condenser coil 12 to a separator 13 from which the air passes off through the non-return valve 15 while the condensed refrigerant returns through the float-controlled pipe 16 to the evaporator. The operating vapour for the ejector is supplied through a pipe 8 from a vessel 5 heated either by the vapour passing through the pipe 6 or by an electrical resistance heater. Refrigerant liquid may be supplied to the vessel 5 during interruptions in the operation of the machine through a pipe 18. The current to the electrical heater may be cut-off by a float in the vessel when the liquid level therein falls below a predetermined level to permit the entry of liquid refrigerant through the pipe 18. In a modification, in which the feed of liquid refrigerant to the vessel 5 is continuous, the ejector withdraws air and vapour from the upper part of the condenser and liquid refrigerant from the sump 3 and liquid is returned directly from the separator 13 to the vessel 5. In this case, when the liquid level and the pressure in the vessel are sufficiently high liquid is returned through the pipe 18 to the sump. In another arrangement, the vessel 5 is dispensed with and the ejector is operated by the vapour from the condenser and withdraws liquid refrigerant from the pipe connecting the sump and the evaporator.

Title: Improvements in and relating to hand grenades and the like
IPC: F42C15/21
Filed: 1934-08-31
Abstract: 443,438. Hand grenades. LEBENSART, S., 43, Untere Weissgarberstrasse, Vienna. Aug. 31, 1934, No. 25131. [Class 9 (i)] Relates to hand grenades of the kind comprising two momentum members A, E normally locked by a plurality of safety members which operate automatically in series during flight to release the momentum members. According to the invention, the safety member which operates last is a contractile spring ring C arranged between the momentum members. The momentum members A, B are kept apart by the spring ring C lying between shoulders on the momentum members, and are held in oblique position in their chamber Z by a pin E retained by an external lever K pivoted at K<1> and fastened by a wire clip S. When the clip S is removed and the grenade thrown, the lever K swings round and the pin E is ejected by centrifugal force and a spring H. The spring ring C then gradually rolls down a series of stepped cones A<2>, A<3>, A<4>, and the momentum members A, B extend and move to the axial position with their tapered ends bearing in the concave ends Z<1>, Z<2> of the chamber Z. This arming operation cannot, however, take place until acceleration or excessive centrifugal force has ceased, these forces tending to keep the members A, B together against the action of the spring ring C. On impact, the members move towards each other and a firing-pin a on one strikes a percussion cap b in the other. The pin E is sealed by a ring F. A spring may be provided between the pin E and the lever K. The pin may be attached to the lever. Specifications 260,318 and 275,224, [both in Class 9 (i)], are referred to as prior grenade fuses having contractile spring rings.

Patent GB-594141-A (GB)
Title: Improvements in or relating to methods of splitting fatty materials
IPC: C11C1/04
Filed: 1944-12-18
Abstract: <PICT:0594141/III/1> Fatty materials such as garbage grease, tallow, palm oil, coconut oil, and other animal and vegetable oils or mixtures of them are hydrolysed by contacting the fatty material with water counter-currently at temperatures below splitting temperatures and elevating the temperature of the fatty material and water to splitting temperature intermediate the zones of initial contact. If desired, the splitting may be catalysed through the presence of hydrolysis catalysts such as soaps.  Fatty material and water may be contacted counter-currently in a tower by introducing the fatty material adjacent to the bottom of the tower, introducing the water adjacent to the top of the tower and applying heat to the tower intermediate its ends.  It may be necessary to apply pressure to the tower in order to maintain the water in the liquid phase at splitting temperature.  Both water and fatty material may be heated to a certain extent before their introduction into the tower in order to remove air from the water and to render the fatty material completely fluid.  The amount of heat which is applied intermediate the ends of the tower may be reduced to a minimum by introducing the fatty material and water in a ratio substantially corresponding to the specific heats of the two bodies.  The hydrolysis is catalysed by the presence of free fatty acid, which may be naturally present as in the case of garbage grease or may be introduced by recycling split or partially split fatty material.  In Fig. 2 water enters tower 1 through line 3 and glycerine water is removed through line 24 while fatty material enters through line 8 and fatty acid is removed through line 9.  Heat is applied to the tower through direct steam coils 14 and 15, although outside heating jackets may be employed either in place of or in addition to the steam coils. Additional heat may be applied by introducing superheated water at points in the heating.  A series of trays or baffles 17 may be provided to aid heat exchange and provision may be made for recycling both fatty acid and glycerine water.  The Specification as open to inspection under Sect. 91 refers to a method of hydrolysing a deteriorated fat containing free fatty acid which comprises heating the fat in the presence of water to a splitting temperature and contacting it countercurrently with the water to hydrolyse its remaining fatty glycerides.  This subject-matter does not appear in the Specification as accepted.
