Title: Organosilicon compositions
Inventor: DARLINGTON MICHAEL EDWIN
IPC: H01B3/46
Filed: 1962-02-23
Abstract: A composition, capable of air-drying in the presence of moisture, comprises (1) a benzene soluble organosilicon resin (R/Si=0.9 to 1.8) containing from 0.005 to 1.5 alkoxy radicals per Si atom and in which at least a major proportion of the linkages between Si atoms are Si-O-Si linkages, any remaining linkages being Si-Si and/or Si-R1-Si (R1=divalent hydrocarbon radical), and (2) an aromatic sulphonic acid. Silicon-bonded radicals specified are methyl, ethyl, propyl, vinyl, phenyl, methoxy, ethoxy, propoxy and butoxy.  The resins are generally used in the form of solutions, e.g. in benzene, toluene or xylene.  The compositions harden on exposure to moisture.  In a typical Example (1), a methanol solution of p-toluene sulphonic acid was added to a toluene solution of a resin obtained by methoxylating the high temperature boiling products of the reaction of methyl chloride and silicon.  A glass plate was coated with a film of the mixture, which dried after 10 minutes at room temperature.  Uses: As insulating coatings for electrical components and as protective coatings or varnishes for glass, ceramics, masonry and metals.

Abstract: 939,511. Valves. EMILE EGGER & CO. A.G. March 1, 1960 [March 12, 1959; Sept. 30, 1959], No. 7137/60. Class 135. A valve consisting of elements that are movable in a plane perpendicular to the axis of a flow passage to define an opening of adjustable size but of constant shape is provided with means for preventing the lodgement of dirt &c. on the movable parts. In one embodiment, a polygonal opening is formed by e.g. six movable elements 7, Figs. 1, 2, which are guided by projections 18 slidable in rectilinear slots 19 in part of the housing and caused to move by rotary motion imparted by a screw and nut mechanism 25, 26 to a ring 13 having curvilinear slots 12 engaged by rollers 11 carried by the movable elements 7. That edge of each element 7 that forms a boundary to the polygonal opening is of convex form and has relative sliding engagement with a mating, concave edge of an adjacent element, sharp edges being provided at the corners 10 to give a scraping action along the convex edges. To prevent lodgement of dirt the slots 12, 19 are open-ended, the width of the bearing surface 14 for the ring 13 is less than the depth of the slots 12, and transverse grooves 12<SP>1</SP> are formed at the inner end of each slot 12. Straight grooves 24 in the ring 13 provide scraping edges to cleanse the elements 7. These elements, which are also scraped where they pass between annular grooves 9 in surfaces 5, 6, may themselves be grooved to scrape the surfaces 5, 6. Impurities, e.g. fibrous material, collecting in the grooves 9 ultimately form a felt-like packing. Flushing of the interior of the housing is facilitated by the provision of two nipples 23. A pointer 28 carried by the nut 26 and visible through an aperture 29 indicates the degree of opening of the valve. The co-operating surfaces of adjacent elements 7 may be shaped as at 55, 56, Fig. 4, which Figure also shows how the convex portion of each element may be formed as a separate strip 51 pressed against the adjacent element by a resilient body 53. Sealing rings 58, Fig. 5, may be used to prevent leakage between the elements 7 and the surfaces 5, 6. Further, a sealing ring 64, Fig. 6, may be provided in an annular recess 60 in the ring 13 and pressed into engagement with the elements 7 when the valve is closed by a ring 62 which has a camming engagement with the ring 13.

Title: Improvements in or relating to automatic stopping devices for gramophones
IPC: G11B17/02
Filed: 1939-03-08
Abstract: 512,403. Gramophones. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 8, 1939, No. 7540. Convention date, Feb. 27. [CLass 40 (ii)] Relates to automatic stopping-devices for gramophones, comprising two co-operating contacts, one of which is moved solely by the pickup arm whilst the other is separately driven through a slip coupling at a speed different from that of the first contact, in such a manner that the contacts remain closed during the playing of a record. According to the invention, the contact 18 carried by the pick-up arm 19 is, during record playing, in advance of the other contact 17, which is driven at a higher speed through a slip coupling 22, so that the contacts are opened only when the movement of the arm 19 is accelerated. The contact 17 is mounted on an arm 21 which is supported by a casing 22 frictionally connected to a wheel 16 which is driven by gearing from the turntable spindle 11. During the playing of a record, the contacts 17, 18 remain closed, and maintain an electromagnet 25 energized, the armature of which, 26, holds contacts 28, 29 in the circuit of the driving motor 30 closed. When the pick-up needle enters the run-out groove at the end of the record, the resulting acceleration of the pick-up arm causes the contacts 17, 18 to be opened, so that the magnet 25 is re-energized. The contacts 28, 29 thereupon open and break the motor circuit, and at the same time a tooth 31 on an end of the armature 26 engages a ratchet-wheel 32 frictionally secured to the turntable spindle 11, thus exerting a braking effect. An adjustable tension spring 36 and a compression spring 41 are arranged as shown to neutralize lateral pressure of the needle on the record groove.

Rubber boots and shoes are made by injecting a rubber mix successively into intermittently moving moulds, each reproducing the shape of the finished article, holding each filled mould closed during a period of time sufficient for vulcanising the rubber, and then opening each mould for delivery of a fully shaped article. A number of carriages 2 are driven between guideways 1 by an intermittently moving endless conveyer 10, each carriage 2 carrying a mould 3 provided with an inner core 4. Each mould receives a fabric lining or sock at station A, is closed at station B, and has the rubber mix injected at station C. The mix is poured into the hopper 9 from whence it passes through the apertures 8, when these are not closed by the piston 11a, to the underside of this piston. On the downward stroke of the piston 11a, the mix is injected through the nozzle 10a to the opening 5 in the top of the mould 3. As a carriage 2 reaches the station C, the support 15 is raised slightly by means of the piston 16 to bring the opening 5 into sealing contact with the nozzle 10a. Vulcanisation is effected at stations D-H, and the moulds are opened at station I, either by hand or automatically, finally being inspected and cleaned if necessary, at station L. In another embodiment, the injection device and moulds are horizontally disposed and a screw feed is employed in which case the mould is held against the injection nozzle by a lever acted upon by a control means, a projection on the lever engaging a corresponding projection on the mould.
