Title: Improvements in the process of bleaching organic materials
IPC: D06L4/13
Filed: 1934-12-27
Abstract: Organic materials, chiefly fibrous materials are bleached by hydrogen peroxide in a bath in which the pH value is kept below 7 by the addition of an aliphatic acid, in the absence of free sulphuric, nitric or hydrochloric acid.  Sulphuric acid may however be used indirectly in that it may be added to the bath together with a salt which is converted in the presence of the acid so that an aliphatic acid is produced, together with a sulphate.  Acids which may be used are oxalic acid, formic acid, cetyl alcohol sulphonic acid, stearyl alcohol phosphoric acid, and oleylaminomethane sulphonic acid. Oxydases and other enzymes may be added as activators, and softness may be imparted to the products by protective colloids such as glue or tanning matter. The feel may be improved by a pretreatment with aldehydes.  The bleaching process is not limited to fibrous materials but may also be applied to horn, bone, resin, artificial resin, legumes, maize flour, and the like.  It is stated that the advantage of using an aliphatic acid is to reduce yellowing of the product and in the case of textiles to result in less weakening of the fibres than is the case with other acids.  The bleaching may be effected in a series of baths of increasing strength, and the bleaching liquor may be continuously pumped through the bleaching tank and kept up to strength by the continuous or intermittent addition of ingredients. Two examples are given in which oxalic acid is the aliphatic acid used.  Specifications 28115/97, [Class 15], 362,352, and 404,019 are referred to.  The Specification as open to inspection under Sect. 91 includes subject-matter contained in Specification 37083/34 (as open to inspection under Sect. 91).  This subject-matter does not appear in the Specification as accepted.ALSO:Organic materials including fibres, horn, bone, resin, artificial resin, legumes, maize, flour, and the like are bleached by hydrogen peroxide in a bath in which the pH value is kept below 7 by the addition of an aliphatic acid, in the absence of free sulphuric, nitric or hydrochloric acid.

Abstract: 840,237. Electrical circuit assembly; bending posts; terminal boards. STANDARD TELEPHONES & CABLES Ltd. Nov. 28, 1958 [Dec. 3, 1957], No. 37591/57. Classes 37 and 38 (1). An electrical circuit is manufactured by forming a series of co-planar hairpin loops in a length of wire, and mounting the length of wire on an insulated support by passing the loops through holes in the support to form terminals, at least one of which is bent over, to which component leads may be connected. In the embodiment described with reference to Fig. 1, coplanar hairpin loops 4 are formed in the wire 1, and the end portions are then bent down perpendicular to the plane to form the terminals 3. An insulated board 5 is pierced with holes 6, the spacing of the holes corresponding to that of the terminals which are then pushed through the holes. Further lengths of wire may be produced in a similar manner and may be arranged parallel to each other on the board or may extend to part of their length in one direction and then be bent through an angle. Component leads may be connected to the terminal by binding with thin wire (Fig. 3), clenching the terminals round the wire (Fig. 4) or by inserting the lead in the hole with the terminal and soldering (Fig. 5).

Title: Improvements in the stepwise forging of multi-throw crank-shafts
IPC: B21K1/08
Filed: 1968-08-07
Abstract: 1,201,692. Forging crankshafts. SCHLOEMANN A.G. 7 Aug., 1968 [14 Sept., 1967], No. 37674/68. Heading B3H. A crank-shaft is made from a forged bar 7 with constrictions 6 for journals separated by thickened portions by clamping the shaft between supports 1, 2 and forging the crank-pin 8 between a die 3 and punch 5. Lateral spread of the crank web formed by metal displacement is prevented by die-bars (4), Fig. 2 (not shown), but the breadth of the punch is less than the diameter of the thickened portions so that metal is allowed to flow between the punch and the bars. This metal flow forms bridge-pieces (10) between the crank webs. The punch and die are shaped to the curvature of the crank-pin. The forged crank-shaft is tempered before removal of the bridge-pieces by a gas torch and the machining of the crank-pin and journals.

One or both of the projectors may be of the contour projecting type or alternatively one may be a line locating projector. An image 36 of the cutting tool edge is projected on to a screen 22 of the contour projector 12 which is adjusted to a graticule on the screen and to a graticule on the projector 14. The position of the projector axes is adjusted by the displacement of the carrier 10 along the axes X and Y according to operative data provided, the cutting tool edge being accurately positionable in three perpendicular directions directly related to known parameters of the machine tool on which it is to be used and from which the operative data is established. The use of the projectors also permits the orientation of the cutting tool to be adjusted to obtain the required rake and clearance angles. Although the screens of the projectors 12 and 14 are separate as shown in Fig. 1, an alternative embodiment shown in Fig. 2 indicates the use of a common screen when two contour projectors are used.

Apparatus for continuously mixing liquids in flow in proportionate quantities comprises at least two containers, each holding a different liquid at the same level, and a primary suction conduit branched off into suction branch conduits each branch conduit having the same hydraulic resistance as each of the other branch conduits one or more of which is or are immersed in the liquid of one of the containers, one or more of the other branch conduits being immersed in the liquid of the other container(s). As shown, a pump 15 transfers liquid fertilizer 4 from a container 3 to a container 13 floating in a water container 1, the supply of water through a feed pipe 18 being controlled by a float 17. A pump 5 draws liquid from suction conduits 6, 7 from each of which are branched eight branch conduits 9, 10 respectively, a conduit 10 being connected with a suction conduit 11 from which are branched eight conduits 12, one of which depends into the containers 13. Fertilizer 4 will thus be added to the water in a preparation of 1:128 or, with the conduit 6 cut off by a valve 8, in a proportion of 1: 64.

Each end of the member may be independently adjusted vertically by an associated pair of sensors, 5, 6 arranged respectively in front of and behind the end of the blade. Time delay is incorporated in the system to permit of the system tolerating minor variations of capacitance. A cross fall device, such as described Specification 1338572, may be incorporated in the system. Specification 1372271 is referred to.

Abstract: 360,720. Gas - washing process. MELCHES, H., 153, Bredeneyerstrasse, Bredeney, Essen, Germany. Dec. 16, 1930, No. 37951. [Class 55 (ii).] In a process for obtaining light benzol from distillation gases, the latter freed from naphthalene and phenol by spraying with water are treated with a quantity of washing oil exceeding the usual quantity by at least one third, so that heavy benzols are washed from the gases, the light benzol going with them. The quantity of oil used is such that not more than 1À6 per cent of benzols are extracted and the viscosity of the oil does not exceed 2‹ Engler at 20‹ C. The enriched washing oil, after preheating to 150‹ C., is treated with steam in a separator. In an example, a coal distillation gas containing 12700 grains of light benzol per 1000 cubic feet of gas is washed with 12À4 gallons of washing oil, which allows for a benzol enrichment of 16 per cent.
