Patent GB-1117751-A (GB)
Title: Production of stiffening materials
IPC: D04H3/16
Filed: 1965-06-09
Abstract: Iron-on stiffening material is produced by continuously depositing filaments of thermoplastic material as a web on a continuously moving woven or non-woven textile material and causing the filaments to fuse to one another.  The filaments may be continuously extruded in say molten or dissolved form as continuous filaments immediately prior to their formation into the web, stretched and then deposited as a web, on to the textile material.  The filaments can be deposited unset, their surfaces at least still being tacky to cause them to fuse to one another, or after setting when the web is heated to fuse the filaments.  The filaments may be set by cooling or evaporation, or by completing the polymerisation in the case of a prepolymer.  Mixtures of thermoplastic filaments may be used.  The web on the textile material may be so heated that the filamentary structure of the filaments is destroyed and the thermoplastic material contracts into discrete particles giving a discontinuous and air permeable coating. Such heating may be by say hot air or infra-red radiation, and the two heating stages may be combined so that the filaments fuse to one another and almost immediately lose their filamentary structure. When a particulate coating has been formed the material may be passed through a cold calender to flatten the particles.  In one embodiment, filaments of a copolyamide of caprolactam, hexamethylene diamine adipate and benzenesulphonic acid butyl amide are extruded from the melt, stretched and set by air streams, deposited on a textile material and heated to form particles.  The nature of the particulate coating can be varied by changing the diameter of the filaments and the deposition and heating conditions.  In a modified method, the web of filaments of the thermoplastic material is formed on a carrier, the filaments are caused to fuse to one another or to contract to particles as above, and the thermoplastic material is subsequently transferred to the textile material by hot pressing. The carrier may be of paper having a silicone coating.

Title: Process for the preparation of intermediates in the synthesis of steroids and the products of such process
IPC: C07C59/90
Filed: 1951-10-22
Abstract: The invention comprises 1-hydroxy-4-methoxy-7-keto-13-methyl-5 : 6 : 7 : 9 : 10 : 13-hexahydrophenanthrene <FORM:0702012/IV(b)/1> which is prepared by reacting 5-hydroxy-8-methoxy-1-methyl-tetralone-2 with diethylamino-butanone-2 in an anhydrous organic solvent in the presence of an alkaline condensing agent.  Specified condensing agents include alkali metal alkoxides and amides, in particular potassium ethoxide.  The intermediate 5-hydroxy-8-methoxy-1-methyl-tetralone-2 is prepared as follows:-Hydroquinone dimethyl ether is reacted with succinic anhydride in presence of aluminium chloride to give b -[2-hydroxy - 5 - methoxybenzoyl] - propionic acid, which is hydrogenated to g -[2-hydroxy-5-methoxy phenyl]-butyric acid.  This upon ringclosure yields 5-hydroxy-8-methoxy tetralone-1, which on treatment with methyl magnesium iodide, followed by vacuum distillation gives 1 - hydroxy - 4 - methoxy - 5 - methyl - 7 : 8 - dihydro-naphthalene. This substance is reacted with osmium tetroxide to produce 1 : 5 : 6-trihydroxy - 4 - methoxy - 5 - methyl - 5 : 6 : 7 : 8 - tetrahydro-naphthalene, which on treatment with acid yields the desired 5-hydroxy-8-methoxy - 1 - methyl - tetralone - 2.  In an example, diethylamino-butanone-2 is converted to its methiodide, which is then treated with anhydrous ethanolic 5-hydroxy-8-methoxy-1-methyl-tetralone-2 under nitrogen.  Potassium ethoxide is added, and when reaction is complete, excess sulphuric acid 1-hydroxy-4-methoxy-7-keto-13-methyl-5 : 6 : 7 : 9 : 10 : 13-hexahydrophenanthrene is isolated with ether.  A detailed description of the preparation of the various intermediates is also given.

Title: Improvements in or relating to multiple gas discharge tubes
Inventor: BAKER GEORGE THOMAS
IPC: H01J17/48
Filed: 1956-08-10
Abstract: 828,325. Multi-gap cold-cathode tubes. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Aug. 9, 1957 [Aug. 10, 1956], No. 24594/56. Class 39(1). [Also in Group XXXIX] A multi-electrode gas discharge tube has a glass envelope in which a plurality of electrodes capable of supporting independent discharges and also interconnections between certain of the electrodes are constituted by metallic films deposited on the inner surface of the glass envelope. The tube shown in Fig. 4 is produced by taking two flat glass plates 1 which may measure 4 by 4 inches and depositing thereon by a process such as evaporation a thin sheet of metal such as nickel of such a size as to leave a margin 3 of uncovered glass on three sides of each plate and a projection of metal on the fourth side which is split and has portions removed to form a number of connecting tags 4. The metal is then formed into the pattern shown, for example by means of a resistant mask and an etching or similar process, thus producing ten rows of electrodes 6 connected by strips 7 and separated by guard electrodes 8. Alternatively, the pattern may be produced during the original evaporation operation by means of a screen. The two glass plates are then dished by heating, turned through 90 degrees relative to one another and sealed together, exhausting and filling with gas following usual practice. If the metal used to form the electrodes is unsuitable for forming a glass-to-metal seal, a different metal may be deposited thereon to form the tags 4. An " eggbox " of insulating material such as mica may be provided between the glass plates 1, each cell of the eggbox enclosing two electrodes 6, in which case it may be possible to dispense with the guard electrodes 8. The tube provides an electronic equivalent of an automatic telephony crossbar switch. The construction is also applicable to multi-electrode tubes of known type in which a single discharge is caused to move from electrode to electrode, or in which a single discharge is produced between a common electrode and a selected one of a plurality of electrodes.
