Title: Improvements in or relating to the production of metallic designs on non-metallic materials
IPC: B44C1/22
Filed: 1943-06-02
Abstract: 567,503. Photographic processes. KERRIDGE, F. E., and JOHNSON, MATTHEY, & CO., Ltd. June 2, 1943, Nos. 8821/43 and 7144/44. [Class 98 (ii)] [Also in Group XV] A metallic design is produced on a non- metallic material by a process comprising the following steps : (a) coating the non-metallic material with silver, gold or palladium; (b) coating this metal surface with a film of lightsensitized glue or gelatin and processing said film by photographic methods to produce a positive image in glue or gelatin of the desired design ; (c) hardening said image to give a resist ; (d) removing the metal not covered by said resist by etching with a solution of bromine or iodine in a liquid alcohol ester not readily attacked by these halogens, thus leaving the design in metal below the resist ; and (e) firing the article to burn away the resist and cause the metallic design to adhere firmly to the non-metallic material. The metal in step (a) is applied by spinning a film of " liquid metal " on to the surface and then firing it. The " liquid metal " consists of solutions of sulphoresinates or resinates of the metals in essential oils and liquids such as cyclohexanol and benzyl alcohol. The glue or gelatin of step (b) is rendered light sensitive by the addition of a soluble chromate or bichromate and may contain a wetting agent such as " Perminal " (Registered Trade Mark). The resist is formed by heating or by treatment with formaldehyde or chrome alum. Etching agents used are solutions of bromine or iodine in non-aqueous solvents, while fine sawdust or levigated alumina may be incorporated in the bath. Adherence of "liquid metal is improved by the presence of bismuth or other metal resinate. A final step (f) of applying an electro-plated coating of a metal may be carried out if desired. Rhodium is the preferred metal for this step.

In the arrangement shown in Fig. 3 alternating current is first rectified by discharge tubes 4, 5 the anodes 11 of which are connected to the secondary windings 7 of a double transformer and the cathodes 12 are heated by transformers 14; the pulsating current taken from the common terminals 8, 13 for the load 2 is then smoothed by passing it through discharge tube 52, the grid 57 of which is connected through a resistance 60 and battery 59 to the positive lead 58; grids 22, 23 in the tubes 4, 5 may also be connected to the battery, and condensers may be added as shown to increase the steadying effect. In a modified arrangement the tube 52 is omitted. the tubes 4, 5 themselves being controlled so as to smooth as well as rectify the current bv connecting their grids to the battery as before. The Specification as open to inspection under Sect. 91 (3) (a) comprised also an alternative arrangement shown in Fig. 3, (Cancelled) wherein the grids 22, 23 are connected between a simple discharge tube 41 of corresponding breaking-down voltage and a resistance 42 across the direct current leads.

Patent GB-906464-A (GB)
Title: A cyclic process for the production of alpha olefins
IPC: C07C2/88
Filed: 1960-03-15
Abstract: Alpha olefins are produced in a cyclic process which comprises (1) thermally decomposing a complex of the formula K[AlR2X2], in which R is an alkyl radical or substituted alkyl radical of at least two carbon atoms and having no branching or unsaturation on the carbon bonded to aluminium and X is chlorine or bromine, to produce a distillate comprising R2AlX and AlR3 and a residue of KX and K[AlR2X2] and possibly K[AlRX3]; (2) reacting the distillate from (1) with ethylene at 90-150 DEG C. and elevated pressure to build up the alkyl groups of the aluminium compounds; (3) displacing the higher alkyl groups with ethylene or other alpha olefin in the presence of nickel, cobalt or platinum; (4) mixing the product with the residue from (1) to reform the complex; (5) separating the olefins containing nickel, cobalt or platinum from the complex K[AlR2X2] which is recycled to step (1).  Steps (3) and (4) may be reversed or part of the residue from step (1) may be added to the product of (2) and the remainder added after the displacement (3).  If desired the process may be begun at step (2) with a mixture of R2AlX and AlR3 and after step (3) KX with AlR3 if necessary is added to form the complex which is then decomposed in step (1). Separation of the complex from the olefins in step (5) may be by running off the lower liquid complex phase or by allowing it to cool to form a solid mass and the olefins poured off.  The complex may be extracted with an aliphatic hydrocarbon to remove traces of olefins.  The olefins are distilled to separate them from the nickel cobalt or platinum.  Suitable displacing olefins are ethylene, propylene and butene-1; the first and last yield eventually olefins with an even number of carbon atoms, propylene yields olefins with an odd number.  If desired different displacing olefins may be used from cycle to cycle. Specifications 770,707, 777,152 and 879,269 are referred to.

The surfaces of the walls 2a and 3 are covered with layers 4 of metal having a high reflective power for the radiation emitted by the hot sheet. Aluminium or highly-polished steel are suitable metals for the layers 4, and the aluminium may be sprayed on to the wall surfaces. In another construction, shown in Fig. 2, the walls 6 are supported by cables 13, so that they can be lifted with the sheet while the latter is passing from the furnace to the cooler, and then removed to allow the sheet to be cooled. In another construction, the walls are provided with top, bottom and side pieces to form a bin-like casing which encloses the sheet. This casing is heated in an auxiliary furnace, so that the glass sheet is surrounded by heated walls while moving from the furnace to the cooler.

Filed: 1975-03-07
Abstract: Novel 2-tetrahydrofurfuryl-6-7-benzomorphans of the accompanying formula I, in which     R<1> denotes methyl, ethyl or propyl;   R<2> denotes hydrogen, methyl or ethyl;   R<3> denotes hydrogen or methyl; and R<4> denotes hydrogen, alkyl having 1 to 4 carbon atoms or acyl having 2 to 5 carbon atoms, are prepared by introducing the tetrahydrofurfuryl radical into appropriately substituted norbenzomorphans by the methods of N-alkylation. The resulting bases of the formula I can then be converted into their acid addition salts. The compounds of the formula I and their acid addition salts are distinguished by a therapeutically utilisable action on the central nervous system. Particularly to be emphasised is their analgesic action, which frequently exceeds that of morphine, without exhibiting the undesired side effects of morphine, e.g. the addictive action. <IMAGE>
