[Also in Divisions B2 and C3] A cap for a bottle, &c., has a sealing disc coated on one side with a non-tacky thermoplastic layer and liquid-filled micro-capsules, the liquid being a plasticizer and reacting with the layer to make it sticky when the sheet is compressed to rupture the micro-capsules. Thus, on securing the cap to its bottle, &c., the sealing disc which it contains is stuck to the bottle neck. As shown, a screw-threaded bottle cap 15 has an inner lip 18 around its skirt which holds in place a sealing disc 12, 13. The sealing disc comprises a base layer (11), Fig. 1 (not shown), of cardboard (which may include a metallic foil laminate) or resilient plastics, coated on one side with a weak adhesive wax, &c. layer (12) carrying a membrane (13) of glassine, metal foil, plastics, impregnated, &c. paper, in turn coated on its outside with a layer (14) of material containing liquid-filled micro-capsules. The non-sticky thermoplastic layer (14) may be, e.g. polyvinyl acetate, &c., and the liquid plasticizer diethyl phthalate, &c. Alternatively the coated layer (14) may be ethyl cellulose, cellulose acetate, or cellulose nitrate. When the bottle cap 15, Fig. 4, is screwed home, the sealing disc 12, 13, &c. sticks to the neck of the bottle, &c. 16.

Patent GB-837799-A (GB)
Title: Process for producing alcohols
IPC: C07C29/16
Filed: 1958-07-14
Abstract: Alcohols are produced by a process comprising reacting an olefine with hydrogen and carbon monoxide in the presence of a hydroformylation reaction catalyst at elevated temperature and pressure to produce a mixture containing an aldehyde having one more carbon atom than the starting olefine, unreacted hydrogen, carbon monoxide and olefine, dissolved catalyst and polymeric material; removing from the mixture the unreacted hydrogen and carbon monoxide and dissolved hydroformylation catalyst; fractionating the remaining mixture in the presence of steam to remove at least some of the unreacted olefine; subjecting the remainder of the mixture to catalytic hydrogenation to obtain an alcohol product; and thereafter recovering the alcohol from the product.  Mono-olefines or diolefines and straight or branched olefines or cyclo-olefines may be used as starting materials. Hydrogen to carbon monoxide molar ratio may vary from 0.75 : 1 to 5 : 1.  The preferred temperature range for the hydroformylation is 149-191 DEG  C. and the preferred pressure is above 105 kg./sq. cm.  The preferred hydroformylation catalyst is a cobalt salt of an organic acid, e.g. the octanoate or naphthenate. At least one mol. of hydrogen and of carbon monoxide is used for each mol. of olefine.  The cobalt carbonyl and other metal carbonyls which may be present can be removed, for example, by passing the hydroformylation product through a heated zone packed with pumice, preferably at 93-204 DEG  C. and under a pressure of 1.75-35 kg./sq. cm.  In this zone unreacted synthesis gas and carbon monoxide may be removed.  The remaining gas is then fractionated in the presence of steam, preferably at 38-288 DEG  C., and a pressure of 0.07 to 3.5 kg./sq. cm., to remove at least some of the unreacted olefine and the remainder of the product is passed to the hydrogenation zone. Preferably nickel is used as catalyst and the hydrogenation is carried out at 121-232 DEG  C. and at a pressure of 35 to 140 kgs./sq. cm.

Abstract: 766,169. Semi-conductor devices. RADIO CORPORATION OF AMERICA. Aug. 4, 1954 [Sept. 1, 1953], No. 22646/54. Class 37. A single crystal semi-conductor of germanium or silicon of predetermined type and conductivity is made by using vanadium, niobium or tantalum as the impurities. The crystal is produced by a zone-levelling process, i.e. causing a relatively narrow molten zone to traverse the length of an elongated body of semi-conductor material, the impurity material being added at one end to be progressively distributed throughout the molten zone. A small crystal of semi-conductor is placed adjacent to the impurity to guide the ingot into a single crystal. Relative quantities of pure germanium and vanadium are given for stated conductivities. N-type germanium produced as above may be made into a junction transistor (Fig. 2), by the addition of indium electrodes 7, 8 with leads 12, 14, and a connector 16 to the base material 4, or into a point contact transistor (Fig. 3) by the addition of two metal wires 30, 32 sharpened to chisel points which are pressed against the surface 25 of the germanium wafer 22.
