Filed: 1924-04-28
Abstract: 237,029. Newbon, H. A. Aprii 28, 1924. Projectors and projectiles.-A toy projector firing a rod or arrow, and of the kind in which the propelling agent is in the form of a loop distended round the end of the rearwardly projecting end of the projectile, is furnished with a stop or holding device for the projectile comprising a spring-influenced pivoted member e, Fig. 1, which jams the projectile c in the barrel b. The member may be integral with the trigger as shown, or a separate trigger may be provided. The holding device may take the form of a member sliding transversely to the projectile, or in an inclined direction and acting as a wedge ; it may also be formed as a pair of movable gripping jaws. The tail feathers r, Fig. 7, are slidably mounted on the arrow so as to allow it to be placed in the barrel for firing, the tail feathers slipping back to their normal position when the arrow is fired.

Title: Method of shrinking fabric
IPC: D06C21/00
Filed: 1976-03-17
Abstract: 1527933 Shrinking fabric P ALBERTO 17 March 1976 [3 April 1975] 10793/76 Heading D1S A fabric 5 is shrunk by overfeeding the fabric into a chamber I or 10 so as to cause it to take up undulant form in which the undulated fabric substantially fills the chamber with the peaks and troughs of the undulations bearing against opposed longitudinal walls of the chamber whereby the undulated fabric is mechanically compressed, and injecting steam into the chamber. In one embodiment, Figs. 1 and 1a, steam is injected into the chamber 1 by nozzles 2. Rollers 3, 4 continuously overfeed and compress the fabric into the chamber 1 which has a cross-section decreasing in the direction of advancement of the fabric. A gate 6 pivotable about a hinge 7 is provided at the chamber outlet and is operable either by the pressure of the fabric thereon reaching a predetermined limit and overcoming the force of a spring 8, or by an independent control operating at regular time intervals according to the feed rate of the fabric at the chamber inlet. Instead of the spring 8, a compressed-air device may be used. In a modification, Fig. 2 (not shown), the outlet gate is omitted and the cross-section of the chamber decreases sharply towards the outlet. In another embodiment, Fig. 3a, the fabric 5 is over fed by rollers 12, 12' and is compressed intermittently within the chamber 10 by a reciprocating piston 11 which moves from the left, Fig. 3a, of the rollers 12, 12' to the position shown. A gate 6, similar to that of Fig. 1, is provided. Instead of being horizontal, as shown, the axis of the chamber 1 or 10 may be inclined to the horizontal or vertical.

A fuel assembly consists of sleeves 7 which contain clusters of fuel rods 14, have spigots 12 which fit sockets 11 on adjacent sleeves, and are locked together by parts of grids 18 which locate the fuel rods. Each grid has radial arms and concentric rings. Some of the arms are inserted through slots 9 into holes 8 in the sleeves and are locked in by collars 33, their ends being split and bent over as shown at 60 (Fig. 6); the other arms bear on the inner walls of the sleeves. Each arm and ring is made from two stainless steel strips of plano-convex cross section joined on their plane sides; the strips are indented to form sockets 17 for the ends of the fuel rods and are notched where arms and rings cross. An auxiliary grid 20 spaces the rods during assembly; space is left between the grids and in sockets 17 for fuel expansion. The assembly also includes a neutron scattering plug and is fastened to a steel tube by which it can be lifted from a reactor; it can be lifted in tension by a tie rod passing through ferrule 21 in the grid 18.

Title: Improvements in the esterification of fatty acids and mixtures containing fatty acids
IPC: C11C3/02
Filed: 1930-04-05
Abstract: In the esterification of long-chain fatty acids or mixtures thereof with dihydric or polyhydric aliphatic alcohols, the acids are treated with a quantity of alcohol exceeding that required for complete esterification, then a quantity of fatty acids exceeding that required for esterification of the alcohol remaining is added, and finally the remainder of fatty acid is removed by a method which is not injurious to the esters obtained, e.g. by extraction with ethyl alcohol, by distillation with steam or other vaporized inert liquid, preferably in vacuo, as described, for example, in Specifications 213,267 and 235,792, [both in Class 32, Distilling &c.], or by washing with dilute aqueous alkali.  This process is very useful in the treatment of acids containing a considerable proportion of "abnormal" acids, such as hydroxy carboxylic acids and acids of very high molecular weight, such as are formed by fermentation and decomposition of such initial materials as seeds and residues from the pressing of olives, for fractionation into "abnormal" acids and esters of "normal" fatty acids is avoided, and the alcohol used is completely esterified. The treatment of the fatty acids of train oil, sulphur olive oil, and sanza olive oil is referred to, and examples are given of the production of esters of sanza olive oil acids with glycerol and of sulphur olive oil acids with ethylene glycol.

It is stated that the resulting product is stable in air and that the electropositive metal can be liberated by heat.  In preparing the material, oxides of barium, strontium, calcium, and lithium are preferable and p  carbonate of sodium.  The process is not practically possible for caesium and barely so for potassium.  When oxides are employed they may be heated in vacuo instead of in hydrogen, and at a temperature of only 700 DEG  C. gas being continually pumped out.ALSO:Relates to the production of deposits of alkali and alkaline earth metals within sealed vessels for photo-electric cathodes, gettering and other purposes.

Title: Improvements in or relating to articles comprising silicon carbide
IPC: H01B1/04
Filed: 1938-04-11
Abstract: 513,728. Electric resistances. TENNANT, W. J. (Carborundum Co.) April 11, 1938, No. 11100. [Class 37] [Also in Group. III] Articles such as electrical resistances are formed of a plurality of silicon-carbide-containing parts by integrally uniting the parts by means of welds containing silicon carbide. The silicon-carbide-containing parts may be formed by placing a part preformed from carbonaceous material adjacent one containing silicon carbide with a layer of carbonaceous welding material between them and heating the article in the presence of silicon so that silicon permeates the joint to weld the parts together and permeates the carbonaceous part to convert it into a siliconized silicon-carbide body. A suitable carbonizable welding material is a paste formed of casein and water, another comprises a paste of cereal flour, carbon and charcoal of a consistency of thick mortar for large and robust bodies or of a consistency of paint for smaller articles. The surfaces to be joined should be generously wetted with casein' glue and the excess wiped off. When the parts are joined together by the paste they are dusted with silicon powder and on heating to over 1800‹C. the joint is permeated by the silicon while if one of the parts is of carbonaceous matter it also is permeated by silicon and since it is of lower specific resistance than parts formed of recrystallized silicon carbide it is suitable as a terminal, and where the latter is used as a heating element. Examples of assemblies according to the process are shown in Figs. 1 and 2. In Fig. 1, 10 denotes recrystallized sillicon carbide parts, 11 denotes the terminal ends produced according to the process and 12 the welds. In Fig. 2 parts 13, 14 and 15 are welded together at 16. Specifications 366,605 and 513,265 are referred to.

Abstract: 543,707. Surfacing moulds and dies. BOWEN, E. WINDSOR-. July 4, 1940, No. 11250. [Class 87 (ii)] [Also in Group XXXVI] An aluminium or aluminium alloy mould or die for plastic materials has its working surface anodized, i.e. coated with an integral film of aluminium oxide by an electro-chemical pro-. cess. The surface prior to anodizing may be smoothed, or roughened as by etching. The latter will enable the anodized surface to increase its heat conductivity, and will give a microscopic porosity which will absorb gases. When made porous the surface may be impregnated with inhibitors or lubricant, such as graphite. Alternatively the oxide coating may be sealed by treating with salts or high temperature water thus imparting to it a non-adhesive condition. For extrusion or drawing dies the electrolyte &c. is chosen to give a hard coating. The exterior of the mould or die may also be anodized, and may be furnished with cooling fins &c.
