Title: Improvements in or relating to opening and closing devices for sliding doors and the like
IPC: E05F15/56
Filed: 1934-03-27
Abstract: 421,433. Door-operating mechanism. KIEKERT, F., and KIEKERT, F. W., (trading as KIEKERT SOHNE, A.), Heiligenhaus, Rhineland. March 27, 1934, No. 9563. [Class 65 (i)] Sliding doors for vehicles are connected to power operating means by a device, carried on the door, which can be rendered inoperative at any time by means of a handle or the like on the door to allow movement of the door by hand. In the form shown, applied to a sliding door 1 carried on a track 3, an electric motor 6 drives a screw shaft 4 on which works a nut 8 having means to prevent its rotation ; the door carries a bolt 14, operated by a handle 13, which enters a notch in the under side of the nut 8 to connect the door to the nut for operation by the motor 6. The door can be disconnected for hand operation at any time and in any position by operating the handle 13 to withdraw the bolt 14; if the door has been moved by hand and the motor is then started, the nut 8 will automatically engage with the bolt 14 on reaching it, and the movement of the door will thus be completed by the motor. In the event of failure of the motor, the nut 8 may be brought to the position shown by means of a handwheel 7 to act as a keeper for engagement with the bolt 14 to hold the door closed ; the bolt 14 may also have a projection at the top to engage a separate fixed keeper. The nut 8 may be constructed so that the bolt 14 is free to move away from it in one direction, so that the motor serves only for opening or only for closing the door, the other movement being effected by hand. The nut 8 may be replaced by a halfnut carried on a lever pivoted on the door and operated from the handle 13, or by a pair of teeth formed in the top of the bolt 14 to engage the screw 4. In a modification, the handle 13 may close a switch controlling the motor, and in this case a half-nut taking the place of the nut 8 may be electromagnetically drawn into engagement with the screw on energization of the motor in place of mechanical operation by the handle. Double doors may be operated from a single motor by extending the shaft 4 and forming a thread of the opposite hand on the other part of it or by interconnecting the doors by a cable or other arrangement so that both are .moved by operation of one of them. In modified forms of drive, the engaging member 8 may be fixed to a long internally-threaded tube engaged by a short thread on a shaft driven by the motor, or it may be operated by endless chain or fixed to a rack with straight or skew teeth engaging a pinion or a conical worm on the motor shaft. The doors may be hydraulically operated, the member 8 being fixed to the piston-rod of a hydraulic cylinder ; double doors may be operated by separate cylinders or by interconnection.

Title: Improvements in the process of manufacturing dyes
IPC: C09B49/12
Filed: 1925-04-14
Abstract: Dyes are prepared by heating perylene or its derivatives, except dioxyperylene, with phosphorus trisulphide or pentasulphide, preferably in the presence of a diluting agent such as kieselguhr. The products on oxidation yield other dyes of a sulphonic acid nature, whilst treatment with sulphur or a difficulty-fusible metallic sulphide produces sulphur dyes. According to the examples, (1) perylene is heated with phosphorus trisulphide or pentasulphide in the presence of kieselguhr: the mass is boiled with water and then with dilute acid, filtered off, and the dye isolated by solution in alkali and precipitation with acid; the product in suspension in acetic acid dyes wool red and dyes cotton the same colour from an alkaline solution; the products obtained by the similar treatment of perylene-3 : 10-quinone and tetrachloroperylene also dye cotton and wool red; (2) the compound resulting from the interaction of perylene with phosphorus pentasulphide is oxidized in alkali solution with hydrogen peroxide and precipitated with acid; in acetic acid suspension it dyes wool an orange colour; the oxidation may also be effected on the fibre; (3) by melting the compound obtained by interaction of perylene and phosphorus pentasulphide with sodium sulphide and sulphur, a dye results which, in sodium sulphide solution, colours cotton a moss green; (4) dibenzoylperylene is heated with zinc sulphide and phosphorus pentasulphide; the product obtained after 30 minutes heating dyes wool and cotton blue, whilst that produced after 90 minutes heating dyes wool and cotton a bluish green.ALSO:The dye obtained by the interaction of perylene with phosphorus pentasulphide is oxidized upon the fibre with hydrogen peroxide in alkaline solution.

Title: Improvements in or relating to resinous ester products
IPC: C08G63/553
Filed: 1941-07-31
Abstract: 552,643. Varnishes &c. derived from resinous ester products. BAKELITE, Ltd. July 31, 1941, No. 9756. Convention date, Aug. 3, 1940. [Class 2 (iii)] Complex resinous ester products suitable for use in the manufacture of varnishes and enamels comprise the re-action product of a polyhydric alcohol, rosin or other naturally occurring acid resin and an addition compound of maleic anhydride with a low molecular weight conjugated diolefine or a mixture of such diolefines. Specified polyhydric alcohols are glycerol, pentaerythritol, mannitol and sorbitol ; other acid resins include copal (Manilla or Congo) resins or ester gum ; and specified conjugated diolefines are cyclopentadiene, methyl cyclopentadiene, isoprene and piperylene. These addition compounds are referred to in " The Chemistry of Synthetic Resins " (Ellis, 1935 ed.) chap. 40; it is preferred to use between 10 and 23 per cent. of these compounds calculated on the weight of rosin taken. The amount of polyhydric alcohol used is preferably such as will give a product with acid value below 15. The complex resinous ester product is useful in the manufacture of varnishes and enamels made from linseed, perilla or fish oils, mixtures such as soya bean with tung or oiticica oils and from dehydrated castor oil. In examples (1) a complex resinous ester product is obtained by heating in an inert atmosphere rosin, glycerol and the addition product of maleic anhydride and cyclopentadiene ; (3) a varnish was obtained by mixing the product with thickened linseed oil, petroleum thinner or mineral spirit and liquid driers ; or (4) dehydrated castor oil replaced the linseed oil; and (5) an enamel was obtained by mixing with titanium oxide, titanium-calcium pigment, zinc oxide and mineral spirit containing zinc naphthenate and other driers. In (7) the process was carried out in two stages, the addition compound of maleic anhydride and cyclopentadiene was heated with pentaerythritol to give a stable solid intermediate product on cooling ; this latter was later heated with rosin to obtain the ester product of the invention and from which (8) a varnish was obtained by mixing with linseed oil, petroleum thinner and driers. In (10) an ester product was obtained from ester gum, the addition compound of cyclopentadiene and maleic anhydride and glycerol. In any of the examples the diolefine may be replaced by a mixture of isoprene, methylcyclopentadiene and piperylene. The use of hydrogenated rosin instead of rosin yielded products of low melting point and dark colour.
