Title: Crankshafts and a method of hardening the same
IPC: C21D9/30
Filed: 1963-04-17
Abstract: <PICT:0959886/C3/1> A crank-shaft has at least one crank-pin 2 with a hardened peripheral layer 11 the volume of which is greater on the side 13 nearer the shaft axis 12.  The hardened layer may be thicker and/or wider on the shaft axis side and may extend into the web radius.  The hardening is performed by electro-inductive heating on a revolving or stationary shaft to prevent distortion and the heating may be varied by control of the inductive current, by varying the gap between the pin and the inductors or by varying the size of the inductor by laminar iron stacks.

Abstract: 379,333. Carbon papers &c. CARIBONUM Ltd. and FRANCIS, F. G., Laura Road, Leyton, London. May 23, 1931, No. 15281. [Class 100 (iv).] Non-smearing transferable coloured coatings on paper or like sheets or webs, remaining transferable in storage, are produced by applying in the cold, by normal printing methods, a composition substantially free from volatile components, and subsequently heating and cooling the applied coating; the composition comprises fluid components in which are suspended one or more solid components which melt when the coating is heated, and on relatively rapid cooling form a homogeneous solid. A typical composition comprises the usual oils and fats, such as petroleum jelly, wool grease, and sesame oil, a synthetic resin, such as resin AA (glyceryl di-aceto abretate), pigment or dye, and a finely-divided wax, such as carnauba wax, which is substantially insoluble in the cold basis. The wax mav be finely divided by spraying the molten wax into a cool chamber, or by heating the mixed components and cooling slowly. The coating may be heated by passing over a heated plate or roller, or by radiant heat.

Title: Removal of bacteria from fluids
IPC: C02F1/461
Filed: 1943-09-20
Abstract: Bacteria are removed from liquid or gas by contact with an anion active material which is, or has been, subjected to a high potential direct current, e.g. 2000 volts.  Resinous products suitable as anion active materials are m-phenylene diamine aldehyde resins polyaminealdehyde resins, alkyl and aryl substituted bigunanide- and guanyl-urea aldehyde resins.  Where such resins do not form insoluble condensation products, these may be insolubilised by treatment with urea, aminotriazines or guanamines.  The resins may be prepared as described in Specifications 561,896 and 562,402.  A suitable resin is prepared by reacting 24 parts urea, 26 parts guanidine nitrate, and 98 parts 37 per cent formalin under reflux in presence of soda ash as catalyst.  The product is heated to 90 DEG  C., 3.6 part HCl added and then cooled to 70 DEG  C. thereby gelling the mixture.  The gel is broken into small pieces, spread on trays and then ground.

Patent GB-835794-A (GB)
Title: Method of dearsenicating arsenical oxidic iron ores and roasted ores
IPC: C22B1/14
Filed: 1957-05-16
Abstract: Arsenical oxidic iron ores and roasted iron pyrites are dearsenicated by subjecting them to a reducing roast at at least 800 DEG  C. exclusively with solid reducing agents, in which the atmosphere above the material being roasted is as nearly neutral as possible, and in which the reducing agent consists of a sulphidic reducing agent present in an amount equivalent to between 1% and 4% FeS2, and a carbonaceous reducing agent, in the form of anthracite or coal, present in an amount equivalent to between 1.8% and 3.6% carbon, exclusive of any solids added as fuel to provide heat for the process by being burnt.  The ore may be mixed with the reducing agent, and if desired pelleted, and this may then be in addition sintered, either by using more of the reducing agent, or by supplying the extra heat by hot gases.  The throughput of air is preferably between 5 and 10 cubic metres per square metre of suction surface per hour at least during its first stages of the treatment, and may after about half the duration of the treatment be raised to above 50 and preferably above 80 cubic metres per hour.  If the ore contains sulphur as sulphate, this sulphur may be used to form some of the sulphidic reducing agent in situ.  Suitable carbonaceous reducing agents include anthracite, brown coal, or charcoal.

Abstract: 889,614. Slat and lath fabrics. HOENIG, L. L. May 19, 1958 [May 17, 1957(2)] Nos. 15757/57 and 15758/57. Class 45. [Also in Group XXII] A flexible sheet comprising a plurality of laths 75 secured together edge to edge by transverse wires 71 is formed by drilling each of the laths at spaced positions determined by reference to one end of the lath, assembling the laths edge to edge with their reference ends and the holes in alignment, feeding a wire through each series of aligned holes and securing the ends of each wire with the outermost laths of the assembly. The touching edges of adjacent laths are respectively concave and convex, or have spaced regions where there is no contact between the edges. A pack of laths is first drilled in the machine shown in Fig. 1 and comprising drilling assemblies 6 which may be placed on any of stations 5 to give the required spacing of holes in the laths. The machine also comprises clamp assemblies 8 which in operation are mounted on stations 7 corresponding with the stations 5 mounting the drilling assemblies. The pack is laid on members 11, the laths being supported on edge and being pressed by shoes 14 of feeding devices 12 against faces 13, Fig. 3, on the drilling assemblies. The lath adjacent the drilling assemblies (the first lath) is pressed downwards to rest on plates 22 which are urged towards the drilling assemblies. Plates 24 are entrained with the plates 22 and press the first lath against faces 26. A locating device 10 moves the first lath so that its reference end engages a reference edge 29. The drilling of the first lath proceeds, self-feeding pneumatic drilling machines 32 feeding their drills through bushes in plates 33, the bushes being arranged to stop the machine should a drill break. After drilling the plates 24 are retracted and the drilled lath is ejected downwardly by devices 9 to permit the feed and drilling of subsequent laths. Shoes 14<SP>1</SP> of the feeding devices are retracted whilst the shoes 14 are urging the laths towards the drilling assemblies. When the gaps between the shoes 14, 14<SP>1</SP> are sufficient a further pack is placed between the shoes and the feed taken over by the shoes 14<SP>1</SP> whilst the shoes 14 are retracted. Sufficient drilled laths to form a sheet are placed on the machine shown in Fig. 5, each of the series of holes in the assembled laths overlying an adjustable cross-member 42. The reference ends of the laths are aligned against a surface 45 by a movable rail 46. A toggle mechanism 53 is operated to grip the laths between clamps formed by members 42, 48, the members 48 being pivoted to the members 42 at 51. The laths are compressed by cylinders 56, and rollers 62 feed wires through guides in the ends of the members 42 to the holes in the lath assembly. After the wires are cut and tensioned nipples 71 are fixed to the ends of the wires and the compression on the laths is released.
