Title: Affixable corner mounts for pictures
IPC: C04B33/04
Filed: 1933-06-19
Abstract: 400,558. Picture mounts. RADO, L., 4, Herwarthstrasse, Berlin. June 19, 1933, No. 17451. Convention date, Dec. 28, 1932. [Class 11.] In an affixable corner mount for pictures which comprises a transparent upper retaining strip having its ends locked over two rightangled edges of an adhesive-carrying base and secured to the underside of the base, the rightangled corner of the base projects beyond the transparent strip in the form of a tab, and the adhesive layer extends to the tip of the tab. The base member a, Fig. 1, may be square or rectangular, and can be cut conveniently and without waste from a strip d, Fig. 5, by means of stair-shaped cuts h<1>, h<2>, g<1>, g<2>, the strip d being fed in the direction of the arrow. Either before or after the detachment of the pieces a<1>, a<2>, &c. the transparent strips are cut off in the form of a long band f from a web e advanced in a direction diagonal to the strip d, and the band f is cut at i<1>, i<2> into lengths b, which have their corners c folded over and stuck to the backs of the pieces a<1>, a<2>. The corner of the base a which projects above the band b ensures that, although the corners c cover the adhesive, the base will nevertheless be firmly stuck to the support. In the modification shown in Fig. 6, the mounts are arrowshaped and are cut from a strip k of material. The bottom corners of the base may be folded over and stuck to the back of the picture which is being mounted.

Abstract: 259,307. Barlow, A. C. July 8, 1925. Metals, depositing; preparing surfaces; treatment after electrolysis. - Aluminium or magnesium or an alloy of either, e.g. duralumin, is prepared for electroplating by treatment with hydrofluoric acid of strength not exceeding 1 per cent. It is then drained and without washing or drying introduced as cathode into a cell in which the anode is of the metal to be deposited and the electrolyte of boric acid. Measures are taken to prevent excessive deposition on the salient parts of the article. After plating the article is washed for an hour in boiling water. The plating may be for protective purposes or as a preparation for tinning or soldering. Nickel, cobalt, cadmium, or iron may be deposited. Nickel may be deposited over a light initial deposit of iron. Copper is deposited over an initial deposit of nickel. The strength of the electrolyte varies according to the metal to be deposited.

Title: Improvements in or relating to adhesive polymeric materials
IPC: C08J5/12
Filed: 1944-09-15
Abstract: Cyclised polymerized alkyl pentadienes are obtained by treating the corresponding polymers with stannic chloride, aluminium tribromide, sulphuric acid, or an organic sulphonic acid either on an open roll mill or in solution in a solvent such as dry benzene or solvent naphtha.  They may be precipitated by dry isopropyl alcohol.  The polymers may be prepared by cooling an alkyl pentadiene such as 2-methyl pentadiene-1,3; 2,5-dimethyl pentadiene-1,3; or 2-methyl-5-ethyl pentadiene-1,3 to a temperature of -20 DEG  to -160 DEG  C. optionally in the presence of ethyl or methyl chloride or other alkyl mono- or poly-halides having up to 4 or 5 carbon atoms, or carbon disulphide or its homologues and analogues, or ethylene, methane, ethane, propane, butane or pentane, or liquid or solid carbon dioxide and then polymerizing in the presence of a Friedel-Craft catalyst preferably aluminium chloride.  The catalyst may be modified by the addition of small amounts of water of hydration or by the substitution of hydroxyl or alkoxide groups for the halide groups. The polymerization is carried out in a solvent such as a hydrocarbon, an alkyl halide or carbon disulphide and is continued till a molecular weight of 20,000 to 500,000 is reached. Specification 565,974 is referred to.ALSO:Cyclised polymerised alkyl pentadienes are used as adhesives for securing together a base solid such as a metal and a non-mineral solid.  The polymerised alkyl pentadiene which may be obtained by the action of a Friedel Craft catalyst on the monomer (see Group IV) is cyclised by treatment with an agent such as stannic chloride, aluminium tribromide, sulphuric acid or an organic sulphonic acid in a soluent such as benzene or petroleum naphtha or in an open mill at elevated temperature.  The cyclised product is precipitated from the reaction solution by dry isopropyl alcohol, and after drying may be used directly or preferably is dissolved in a soluent such as benzene, toluene, xylene, cyclohexane, methyl cyclohexane or mixtures of toluene with di-isobutylene.  Small amounts of fillers and pigments may be added. The non mineral solids may be natural and synthetic rubber, such as polybutadiene, polychloroprene, polyisobutylene, interpolymers of butadiene with styrene and acrylonitrile, and interpolymers of isobutylene with an olefin prepared according to Specification 565,974, [Group IV], phenolformaldehyde and polymethacrylate resins, natural resins such as copal, copal gum, damar or shellac, wood, horn, bone and solid cellulosic products.

(1) The secondary coil 111a of the output coupling is of rectangular spiral form and of metal tubing, and is associated with two series condensers of cylindrical form as shown in plan in Fig. 3. The inner members 111b, 111c of the condensers are linked together by an insulating yoke 411 attached to a plate 511 which slides in guides 611 on the framework, so that the inner members may be jointly adjusted relatively to the outer cylinders 211b, 211c which are secured to the frame. The whole unit is adjustably carried on an earthed member 911. (2) The anode circuit coil of the push-pull pair of transmitting-valves is divided centrally and a pair of condensers, arranged as shown in part sectional elevation in Fig. 6, are interposed. Two coaxial hollow cylinders MT1, MT2 spaced a small distance apart are surrounded by a mica dielectric LM which is held by a metal clamp MBC forming the common central member of the two condensers. The outer end of each cylinder is fixed to or formed integrally with a quadrant member MM2 each of which cooperated with a clamping-band MMC1 and screw MMS1 to receive the vertical ends of the divided anode coil.
