Abstract: 1,198,251. Moulding layered products from powders. BECKMAN-RIIC Ltd. 27 July, 1967 [27 April, 1966], No. 18434/66. Heading B5A. [Also in Division G2] In double beam absorbtion spectroscopy examination wherein one block containing a mixture of known and unknown constituents dis - persed in a transparent carrier is normally compared with a positionally adjustable wedge shaped carrier block containing the known constituent, the wedge shaped block is replaced by a parallel sided block comprising first and second coalesced wedge shaped layers one whereof comprises the known constituent in the carrier and the other only the carrier whereby deviation of the beam arising from a wedge shaped block and the use of compensating means therefore is avoided. The first wedge shaped layer 9 is formed by compressing powder in a die I to a non-coalesced state between a horizontal faced bottom die element 8 and a plunger (4<SP>1</SP>), Fig. 1 (not shown), having an inclined lower face. The second layer 10 is formed by compressing additional powder by a plunger 4 e.g. actuated by an hydraulic press, under a sufficient pressure to coalesce both layers 9 and 10, to form a block having parallel upper and lower faces, with the moulding space sealed by a resilient plunger collar 7 and O ring 6 and connected to a vaccum source via an outlet 5. In forming each layer either the plunger 4 may directly contact the member or an intermediate member may be used.

Abstract: A mixture of gasolene, lubricating oil or other petroleum distillate and an organic dyestuff which tends to separate from such oils, is stabilized by addition of a water-insoluble soap. Fatty or resinous soaps of zinc, calcium, magnesium or aluminium may be used.  In the case of basic organic dye such as spirit blue (a phenylated rosaniline), an organic acid such as oleic, stearic, or benzoic acid may be added.  1 part of stearic acid, 1 part of spirit blue and 2 parts aluminium stearate are dissolved in a little benzol and 1 part of the benzol solution added to 100,000 parts of gasolene.  Spirit blue may be replaced by arylated rosanilines, triphenyl methanes, indulines, indazines, nigrosines, rhodamines or phthaleins.

Filed: 1950-07-25
Abstract: 694,243. Wave-guides. MINISTER OF SUPPLY. July 10, 1951 [July 25, 1950], No. 18524/50. Class 40 (viii). In a dielectric loaded wave -guide the effective dielectric constants of adjacent coaxial tubular regions bounded by nodal surfaces in the guide are different. In the guide shown in Fig. 1 the dielectric forming tube 2 differs from that forming coaxial tubes 1 and 3. In Fig: 2 is shown a manner of obtaining the same result using one dielectric alone other than air. Washers are made from this dielectric, with a greater thickness in region 2 than in regions 1 and 3. Thus the proportion of solid dielectric to air is greateroverthe whole of region 2 than the other regions. The purpose of the invention is to reduce the conduction loss in the metal wall B of the guide. Specifications 647,669, 654,906 and 685,654 are referred to.

Abstract: 269,028. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 26, 1926. Chromium and iron chlorides. - Anhydrous chromic chloride is obtained by acting on ferrochromium, preferably in the form of lumps, with chlorine or gases containing chlorine in such a manner that the reaction once started is maintained by the heat produced. The reaction is preferably carried out in a revolving furnace lined with a heat-insulating substance and fireclay &c. The chlorine is passed through in a counter current and the temperature can be controlled by regulating the flow of chlorine. The iron chloride formed sublimes off at one, end and the chromic chloride is continuously withdrawn at the other. Small quantities of a reducing agent, such as carbon monoxide in the chlorine or carbon in the ferrochromium, may be used. Specification 29325/13 is referred to. Reference has been directed by the Comptroller to Specification 276,120.

Filed: 1919-07-29
Abstract: 153,085. British United Shoe Machinery Co., (United Shoe Machinery Corporation). July 29, 1919. Connecting uppers to insoles.-A manufactured ribbed insole as distinguished from one composed of a single sheet of leather cut to form a rib, is moulded and shaped in the process of making to the exact contour and size of the last bottom to which it is to be applied. The insole is built up of three layers of material, preferably a layer 5, Fig. 1, of textile fabric, such as duck, a layer 6 of leather substitute, such as fibreboard, and a leather skiving 7 which forms the sock surface; the two layers 6, 7 are clinked or died out to a size which will form a blank having the exact area of the last bottom, while the laver 5 is dinked out to a larger size to provide for the formation of the sewing-rib. This layer 5 is placed between moulds 8, 9, Fig. 3, formed, respectively, with a recess 10 and a co-operating marginal rib 11, and having their pressing surfaces of the exact size and contour of the last bottom. As a result of the moulding operation, the layer 5 is drawn in flush with the edge of the mould, and a sewing-rib 12 is formed which is of uniform cross-section and which stands at a uniform angle to all points on the sewing surface whatever the curvature of the insole may be. The moulded layer 5 is preferably left in the mould 8 and the layers 6, 7, treated with adhesive, are pressed and moulded against its unribbed surface by a mould similar to the mould 9 but without the marginal rib 11. The heel end of the insole, particularly when the heel of the shoe is to be secured by " inside " nailing, may be reinforced by a tap 14, Fig. 1, skived at its forward edge 15; this is introduced between the layers 6, 7 before the second moulding operation. In some cases the layer 6 is first moulded against the layer 7 and the two layers are further secured by seams 16, Fig. 4, laid at each side of the rib, after which the layer 7 is applied. In order to provide for the increased thickness of the upper materials at the toe of the shoe, caused by the usual stiffener, and to enable the inseam to be sewed at a uniform height relative to the face of the insole, a strip of material may be removed from the tip of the toe portion of the layer 6, leaving a recess 17, as shown in Fig. 7; alternatively, the same advantages may be obtained by condensing the materials at this part of the insole to a greater extent during the moulding operation.
