Title: Cold-hardenable organosilicon coating compositions
IPC: B05D7/26
Filed: 1957-06-21
Abstract: A cold-hardenable organosilicon coating composition comprises a silane of the formula RnSi(OR1)4-n, wherein each R is an alkyl or aryl radical, R1 is an alkyl radical of 1-4 C atoms and n is 1, 2 or 3, or the dimeric partial hydrolysate thereof, or a mixture of such silanes and/or dimers, and as catalytic hardening agent a salt of Fe or Zn and/or an easily hydrolysable Ti compound.

Buffers, e.g. acetic acid, iron acetate or an alcoholic solution of potassium acetate, may be added when acid-reacting catalysts are used.  The silane mixture may contain traces of HCl and/or chlorosilanes.  In typical examples compositions consist of (1) methyl- and phenyltriethoxysilanes and ferric chloride; (3) ferric chloride and zirconium oxychloride in alcohol, ethyl tri- and dimethyl di-ethoxysilanes and dimethyltetraethoxydisiloxane; (7) ethyltri- and trimethyl-ethoxysilanes, titaniumisopropylate and butyl acetate; (10) a butanol solution of a urea-formaldehyde resin, methyltributoxysilane, dimethyldimethoxysilane and butyl titanate. Pigments, other solvents and organic polymers, in amount of 1 to 70% by weight of the composition, may also be added.  Other organic polymers specified are nitrocellulose, alkyds, epoxy resins, shellac (natural and synthetic), polyesters and copal. Other catalysts disclosed are ferric octoate, titanium tetrachloride, and titanium acetylacetonate.  Uses:  For coating surfaces of materials such as glass, metal, stone, clay, ceramics, wood, lacquer coatings and plastics.
Patent GB-685950-A (GB)
Title: Improvements in or relating to a process and apparatus for the production of artificial fibres
IPC: C03B37/00
Filed: 1947-07-15
Abstract: <PICT:0685950/IV (a)/1> <PICT:0685950/IV (a)/2> A fibre-forming mass in solution or in molten state is extruded through a porous wall having irregular or tortuous fine passages from its inner to its outer face, thus being formed into artificial fibres.  The porous wall may consist of a disc of earthenware, glass or porous metal or of other natural or artificial material.  If desired it may be heated.  The extrusion may be assisted by the direct action of a pulling member or gib which may be complementary with respect to the wall and thus conform thereto, or by centrifugal force.  The fibres may be guided to a winding apparatus which, like the gib, may operate with a greater velocity than that at which the fibres are produced, thus stretching them.  The gib may be made of leather, rubber, glass or metal and may possess a smooth surface.  Suitable materials for spinning include polyamides, polyacrylates, polystyrenes, polyvinylchloride and cellulose esters.  As shown (Fig. 1), a container 1 is provided with a plug 2 having a central opening covered by a porous disc 4 held in position by a tube 5 for the supply of fibre-forming material.  A funnel 7 is fixed into the bottom of the container for withdrawing the fibres.  The container is also fitted with suitable exit and entry pipes for solvents &c.  A plate or gib 9 is mounted on a carrier 12 for movement in a vertical direction, and held in contact with the disc 4 prior to spinning. The molten polyamide or other material is supplied into pipe 5 and, on extrusion through the disc 4, the plate 9 is rapidly lowered to initiate the spinning, the fibres being passed by hand through the funnel 7 to the withdrawing reel 10 and the gib or plate 9 moved clear of the fibres.  Fig. 2 shows a modification in which the fibres are extruded by centrifugal force.  A drum 15 is mounted for rotation, and axially into it projects a supply tube 20 which may also be rotatable.  A porous wall 22 is formed in the lower part of the tube.  As the fibres are extruded through the porous wall they are entrained by the rotating drum and deposited on the circumference.  Gaseous nitrogen or carbon dioixde may be used to blanket the spinning material and prevent oxidation.  The Specification as open to inspection under Sect. 91 refers also to extrusion through wire screens with openings out of register, and to the extrusion of glass.  This subject-matter does not appear in the Specification as accepted.

Title: Closures for sealing containers and a process for making such  closures
IPC: B29C51/06
Filed: 1972-04-27
Abstract: 1361538 Heat-shrinking closures HOUILLERES DU BASSIN DU NORD ET DU PASDE-CALAIS 27 April 1972 [30 April 1971] 19685/72 Heading B8T [Also in Division B5] A closure for a container has a planar part 19 with a central zone 21 having a smaller heatshrinkability than that f of the peripheral zone 22, and a skirt 20 with a tangential shrinkability f<SP>1</SP> larger than its radial shrinkability f, so that when it is heat shrunk on to the container, it tightly grips around the mouth of the container without causing excessive tension in the central region 19. The closure is made from a thermoplastic sheet 17, on an apparatus comprising male and female mould members, 5, 6 respectively. The male member 5 comprises suction vents 7, means for evacuating or pressurizing its interior, and a heated protuberance 11, similar in shape to the container mouth (the outline 1 of which is shown by perforated lines) but with smaller dimensions. The female member 6 has suction vents 7, cooling means and an insulating ring 15, and has dimensions larger than those of the container. The male member 5 is raised above the level of the sheet, and the interior of the member is evacuated. The sheet; above its vitreous transition temperature, is shaped by the heated protuberance 11, and the female member 6 is then lowered until the ring 15 engages the sheet 17. The space between the shaped sheet 17 and the interior wall of the female member is evacuated and pressure is applied inside the male member, distending the shaped sheet against the cooled female member where it hardens. The formed closure shape, which is punched out of the sheet and placed on the container is sealed thereto by placing in a heating tunnel or oven having upper elements which supply less heat than do the side elements, and the closure shrinks on to the container, tending to regain the shape of the protuberance 11.

Abstract: 153,690. Robinson, J., Macrorie, A. K., Grenfell, G. P., and Airey, H. Morris-. Aug. 18, 1919. Wireless signalling; bearings, determining wirelessly.-The intensity of the received waves is caused to control the pitch of the note heard in the telephone. For this purpose, an oscillating thermionic valve is employed, the oscillations generated having a group-frequency which is audible in a telephone in the plate circuit, and the incoming energy is utilized to vary the grid-leak resistance of this valve, thereby varying the pitch of the note. The apparatus is particularly applicable to direction-finding systems. In the arrangement shown in Fig. 2, the oscillating valve 3 has the inductance 4 of its plate circuit coupled to the inductance 5 of the grid circuit. A condenser 6 in the grid circuit is shunted by a leak resistance constituted by the plate-filament path of a valve 8, and the value of this resistance is varied by applying the incoming energy to the grid of the valve 8. The high or low frequency receiving-circuit 13, 14 is coupled to the grid circuit of a valve rectifier 17, the plate circuit of which is connected across a high resistance 16 to the grid circuit of the valve 8. The rectifier 17 may be omitted and the circuit 13, 14 connected inductively to the grid circuit of the valve 8. A source of current may, or may not, be placed in the plate circuit of the valve 3.
