IPC: H03J5/24
Filed: 1936-09-18
Abstract: 478,831. Wireless receiving circuits. GENERAL ELECTRIC CO., Ltd., and BLIGH, N. R. Sept. 18, 1936, No. 25435. [Class 40 (v)] A wireless receiving-set of the kind adapted to receive both on frequencies substantially greater than 30 megacycles (e.g. television frequencies) and substantially less than 30 m.c. (e.g. the normal broadcast range) comprises two electrically separate tuned circuits L1, C1, L<1>1, C<1>1, R1 and L2, C2, L<1>2, C<1>2, R2 the tuning elements C1, C2 of which are unicontrolled, and a switch S by which the circuits are alternatively placed in circuit. By this means the ultra-high-frequency circuit may be wholly and carefully screened as at 13, while merely the inductances L2, L<1>2 of the lower frequency circuit require screening. The triode-hexode frequency changer 1 may be common to the two circuits as shown, or a 'separate valve may be used for each circuit in the latter case the higher frequency valve will be housed within the screen 13. The usual waveband switching arrangements may be additionally provided for the lower frequency unit L2, C2. Specification 454,188 is referred to.

Abstract: 1537364 Transferring chocolate slabs SAPAL SOC ANON DESPLIEUSES AUTOMATIQUES 18 June 1976 [30 July 1975] 25483/76 Heading B8A Slabs T (Fig. 1) of chocolate are picked up by suction heads V carried by arms 22 which are movable axially as well as rotatably on a fixed hollow shaft 13. The slabs are carried upwardly and delivered on a surface 28 whence they are delivered by conveyer pushers 30 (Fig. 4) and tapered guide surfaces (29) (Fig. 5, not shown) to carriers 31 of an endless conveyer. The rotatable movement of the suction heads V on the arms 22 is varied from uniform rotation about the axis of the shaft 13 to produce the changes in attitude of the slabs shown in dotdash lines in Fig. 1. This variation results from the movement of a planet wheel 16 connected by a shaft 5 to the suction heads V (Fig. 2). The planet wheel 16 meshes with a sun wheel 15. The latter has a reduced-diameter toothed portion meshing with teeth on a sector 7 pivotally mounted on a member 8 carried by a plate 4 integral with a drive sprocket 3 in the drive to the arms 22. The sector 7 also has a cam follower (10) (Fig. 3, not shown) which co-operates with a fixed cam groove 11. Thus by the cam groove 11 displacing the sector 7 relative to the plate 4, the sun wheel 15 is rotated and thereby rotates the shape 5 and suction heads V relative to the normal rotational movement of the latter. Another cam follower 20 on a member 21 freely pivotally mounted on the shaft 5 (but axially fixed relative thereto) engages a cam groove 19 to produce axial movement of the shaft 5 and the suction heads V carried thereby. As shown, there are two sets of suction heads V mounted 180 degrees of rotation apart each set being carried by a respective mechanism as described above.

Title: Improvements in the manufacture of artificial filaments, yarns, films and like products
IPC: D01F2/28
Filed: 1931-09-11
Abstract: Artificial filaments, yarns, straw, ribbons, &c. of improved pliability and flexibility are made by incorporating therein a small quantity of a finely divided inorganic or organic solid. The quantity must be insufficient to affect the lustre of the material.  The method is particularly applicable to the manufacture of products made from organic derivatives of cellulose, but it may also be applied in the case of those of the reconstituted cellulose type.  The finely divided material may be added to the spinning solution; or it may be incorporated in the formed products by treatment with a suspension, preferably in the presence of a swelling agent.  Suitable substances to be so incorporated are metal oxides, carbonates, borates, phosphates, silicates such as china clay, talc, and mica; and organic substances such as diacetyl benzidine, diacetyl tolidine dibenzyl benzidine, naphthyl urea, anthraquinone, anthracene, and natural and synthetic resins; and to obtain the best results, the substance is preferably finely divided, for example, the particles thereof should be less than 0,1 to 10 microns.  To the spinning solution there may also be added diethylene glycol, oils or fatty acids; and the solution containing the insoluble material is preferably thoroughly mixed and subjected to the usual filtrations.  In examples, diacetyl benzidine, china clay or zinc oxide is added to a spinning solution of cellulose acetate, and a cellulose acetate yarn after treatment with a swelling agent is introduced into a heated bath containing freshly precipitated aluminium oxide and slightly acidified with hydrochloric acid.

Title: Improvements in taps and valves for controlling the flow of fluids
IPC: F16K31/524
Filed: 1945-10-02
Abstract: 637,364. Manually - actuated valves. KNIGHT, J. T. A. Oct. 2, 1945, No. 25558. [Class 135] A tap or valve comprises a valve body 1 divided into front, intermediate, and rear chambers A, B, C, and has an inlet 4 to the rear chamber, an outlet 3 from the intermediate chamber, and a valve member 9 in the rear chamber mounted on a valve rod 8 adjustably connected to an operating rod 16 in the front chamber which rod 16 is formed between its ends with a part such as the U-shaped part 19 which is engaged by a finger 21 or the like depending from a transverse axle 20 operable by an external lever 22, Fig. 4. As shown, the valve body 1 has a central tapered portion with an apertured rear wall 2 which forms the seat for the valve member 9. The rod 8 has guides 7, 13 formed in the inlet 4 and on a partition 11 respectively. A shield or baffle 14 engages over the guide 13 to minimize leakage past the latter. Any such leakage passes out through an orifice 15 adjacent the outlet 3. The valve rod 8 is adjustably connected by screw means 26 to the rod' 16. The latter is guided in an apertured partition 18 in the front chamber A which is closed by a cap 5. The rod 16 has a downward projection 16b engaging a groove 16c to prevent it from rotating. The axle 20 is rotatable to operate the valve by the U-shaped lever 22, Fig. 4, secured to its ends and straddling the valve body 1. The lever 22 is movable between stops 25, 23, corresponding to the open and closed positions. The horizontal part of the lever may be forced past the stop 23 to hold the valve closed. The valve may also be halted in intermediate positions by serrations or studs engaged by the springy side arms of the lever 22. In a modification the valve rod 8 carries a second valve to close a seating on the partition 11 when the main valve is open and so prevent leakage at the ends of the axle. According to the Provisional Specification the valve may be spring- loaded towards its seat. Another modification is -described in which a conical baffle on the valve rod fits over a conical partition in the valve body. Further, the short lever or finger may be connected to the valve rod by a coupling wire or rod which, when the valve is closed, is substantially axially aligned with the finger and the valve rod. The operating lever may be forked and pass through a gap in the front chamber where its ends are connected to the ends of the transverse pivot rod. The finger lever may be replaced by a U-shaped extension of the operating lever.

Patent GB-891086-A (GB)
Title: Razor blades
IPC: A61K8/58
Filed: 1959-07-27
Abstract: A safety razor blade is treated to facilitate shaving therewith by providing on a cutting edge thereof a coating of an organosilicon polymer (see Group IV(a)) and then air-curing the polymer at an elevated temperature to form a gel.  The initially liquid polymer, e.g. an organopolysiloxane, a silylpolyester or an organostanno-siloxane polymer, may be applied per se or as a solution e.g. in carbon tetrachloride, dioxane, xylene or hexamethyl-disiloxane, to the clean faces of the blade edge, as by dipping, immersion, spraying, flowing from a capillary or by stropping.  The polymer may also contain additives, e.g. molybdenum disulphide and finely divided silica, and siloxane curing catalysts. In Example (1) the blades to be treated are cleaned, dried and mounted on an advancing conveyer band and carried through an applicator station wherein both cutting edges of each blade are advanced longitudinally through laterally open narrow channels supplied with a CCl4 solution of a methylhydrogen siloxane; the treated blades are then advanced to a heater maintained at 320 DEG F., wherein the solvent is evaporated and the siloxane cured to a gel, and thence allowed to cool in air.ALSO:A safety razor blade has on a cutting edge thereof a coating of an organosilicon polymer which has been cured in situ to form a gel and so provide an easier shave than an untreated blade.  The polymers may be used per se or in solution in a solvent, e.g. carbon tetrachloride, dioxane, xylene or hexamethyldisiloxane.  A material such as octamethylcyclotetrasilazane may be applied to the blade and converted in situ to the siloxane.  The coating may also include an additive, e.g. MoS2 or finely-divided SiO2, and may be cured to the gel by heating with or without a curing catalyst, e.g. choline bicarbonate, ammonium hydroxide, piperidine, dibutyl tin dilaurate and zinc naphthenate.  Organo silicon polymers disclosed in the examples have the unit formula: (1, 2, 3, 4, 8, 13, 16) (CH3)H-SiO; (5) (CH3)2SiO; (6) (C2H5)HSiO; (7) (C3H7)HSiO (n-propyl); (9) RRSiO, 13% of the R's are ethyl, 40% are methyl and 47% are H; (10) RRSiO, 29% ethyl, 23% methyl, and 48% H; (11) RRSiO, 30% ethyl and 70% methyl; (12) (C4H9)HSiO (n-butyl); (14) RRSiO, 15% phenyl and 85% methyl; (15) (CH3)HSiO terminated with -OCH2(CF2)CF2H groups; (17) (CH3)2SiOCH2CH2O-; (18) (CH3)2SiO and (CH3)2SnO to provide a ratio of Si:Sn of 19:1; (19) RRSiO, 0,5% vinyl and 99,5% methyl; (20) RRSiO, 0,5% allyl and 99,5% methyl; (21) RRSiO, 50% n-amyl and 50% methyl; and (22) RRSiO, 30% isopropyl, 20% methyl and 50% H.
Patent GB-950216-A (GB)
Title: Reversible material and process for the manufacture of same
IPC: D04H11/00
Filed: 1961-07-17
Abstract: A reversible material comprises a backing fabric, one side of which presents a hairy surface and the other or reverse side presents a non-smooth surface, a layer of filling compound applied to the non-smooth usrface, the layer of filling compound presenting predetermined hollows and raised parts, an adhesive layer applied to the layer of filling compound, and a layer of hairy or thread-like elements applied by a continuous electrostatic flocking process.  The backing fabric may consist of a velvet fabric on one side and the thread-like elements applied to the other side consist of fibres of a synthetic material.  The backing fabric may be composed of threads of various thicknesses capable of producing an effect of relief in the layer of hairy or thread-like elements applied thereto.  The thicker threads of the backing fabric may be laid out in such a manner as to produce the effect of any desired effect, e.g. as corduroy.  The adhesive or filling compound may be a fluid product which hardens in the open air, e.g. compounds of latex.  The hairs of the hairy surface of the fabric backing may be either curly or otherwise. Opposite surfaces of the fabric backing may have respectively hairs of different natures, of different thicknesses, or of the same or of different colours.  The backing may be stretched, e.g. by mechanical means, to avoid the formation of creases therein, at least one layer of a filling compound which hardens in the open air is applied to the non-smooth surface in such manner that predetermined hollows and raised parts remain in this layer and the surface thus treated is coated with an adhesive prior to applying hairy or thread-like elements by continuous electrostatic flocking.  The coating of the reverse side of the backing fabric is carried out so as to provide the desired surface irregularities for that side of the material when completed by the flocking process.  In order to obtain a uniform aspect of layer produced by flocking, the filling coating is applied to obstruct completely all spacings or interstices present in the reverse side of the backing fabric, the continuous surface thus obtained being coated with adhesive and flocked.
