Title: Improvements in or relating to elevator control systems
IPC: B66B1/16
Filed: 1961-07-04
Abstract: 988,365. Elevator control systems. SCHWEIZERISCHEWAGONS - UND AUFZUGEFABRIK A.G. SCHLIEREN-ZURICH. July 4, 1961 [July 5, 1960], No. 24184/61. Drawings to Specification. Heading B8L. A collective control system for a plurality of elevators and in which all the switching devices are statical element switching devices comprises a single time-dependent step-by-step switching means having switching positions corresponding to the number of floors served by the elevators and adapted to be switched at definite time intervals to successive positions in one sense and then to successive positions in the other sense. Upon coincidence of the instantaneous step positions of the time-dependent switching means and of elevator position-dependent stepby-step switching means, which generate signals as a function of the directions of travel and instantaneous positions of the various elevators, additional signals are produced which, in conjunction with the cabin call, floor call and fullload signals, are operable to control the operation of the various elevators automatically. The Specification describes in detail the circuitry of one embodiment of an elevator system having two elevators serving five floors.

The tilt of the laths 28 of a louvre blind enclosed within the air space 19 between panes 15, 16 of a double glazed hermetically sealed unit are controlled individually by electrically produced fields of force which results in a torque which overcomes a restoring torque on the lath, the laths being independently turnable about parallel transversely spaced axes and restored to a preferably open position by a restoring torque exerted by shock proof torsional suspensions 29 that resiliently tension the laths longitudinally while permitting frictionless turning thereof. As shown each end of each thin aluminium lath is doubled over at 38 and welded to the spade like end 37 of a slide rod 36 which slides in a fitting 29 constituted by a pair of rectangular half shells 31, 31<SP>1</SP> of thin aluminium sheet having semicylindrical grooves 32, 32<SP>1</SP> and provides a guiding tube for the spring 33 one end of which abuts lancings 34, 34<SP>1</SP> and the other end of which presses against a cylindrical head 35 of the rod 36.

Title: New phthalocyanine dyestuffs
Inventor: POOLE VICTOR DAVID
IPC: C09B47/08
Filed: 1961-07-07
Abstract: The invention comprises phthalocyanine dyes which contain, attached to carbon atoms of aromatic rings present in the dyestuffs, from 1 to 8 groups of the formula -CH2.S.SO3X where X is an alkali metal atom or an ammonium group.  The aromatic rings may be the benz rings of the phthalocyanine nucleus or they may be aromatic rings attached to said benz rings via a direct link or a bridging atom or group. The dyes are made by treating a phthalocyanine containing 1-8 chloromethyl or bromomethyl groups with an alkali-metal or ammonium thiosulphate, or by treating a phthalocyanine containing 1-8 mercaptomethyl groups with chlorosulphonic acid or sulphur trioxide in the presence of a tertiary base.  Examples are given. Specifications 586,340, 587,636, 681,917 and 927,774 are referred to.ALSO:Phthalocyanine dyes which contain, attached to carbon atoms of aromatic rings present in the dyestuffs, from 1 to 8 groups of the formula -CH2.S.SO3X where X is an alkali-metal atom or ammonium colour cellulose textile materials such as cotton, viscose rayon and linen by dyeing, padding or printing in conjunction with a treatment with thiourea or a water-soluble sulphide such as sodium sulphide. In dyeing, the material is treated with the dye from a bath and then with sulphide at 20 DEG  to 60 DEG C. or with thiourea and optically an alkali such as sodium carbonate at 60 DEG  to 90 DEG C.  In padding, the material is padded through the dye and then through sulphide solution, or through the dye and then thiourea and alkali solution in which case a heat treatment follows.  Alternatively the material is padded through a solution of dye, thiourea and alkali and then subjected to heat treatment.  In printing, the dye is applied in a paste to a textile impregnated with thiourea and a substance which, in the subsequent heat treatment, liberates an acid-binding agent, or to a textile which is subsequently treated with aqueous sulphide. Alternatively the textile is printed with a paste containing dye, thiourea and substance which liberates an acid-binding agent, and then subjected to heating or steaming.

Abstract: 1,127,933. Accumulators activated by wateraddition. GOULD NATIONAL BATTERIES Inc. 7 June, 1966, No. 25216/66. Heading H1B. The invention comprises dry electrical storage batteries activated by addition of water. The batteries consist of (a) a casing enclosing electrode plates and defining a space for electrolyte extending above the plates, (b) a charge of electrolyte confined in a sealed container within this space the container being insoluble in water and insoluble in the electrolyte and (c) a capsule made from a water-soluble material and containing a solvent for the container also within the electrolyte space. The capsule may be made of poly (ethylene oxide), polyvinyl alcohol or methyl cellulose. It may lie above or below the container depending on whether the solvent is heavier or lighter than water. The solvent released on addition of water may be an organic solvent, e.g. benzene, toluene, CCl 4 , or petroleum. This dissolves the electrolyte container, which may be of a vinyl plastic, e.g. polystyrene and polythene, or a wax, and releases the electrolyte. In the case of a leadacid battery the electrolyte in the container may be a gelatinous concentrate prepared from MgO and H 2 SO 4 . Alternatively an H 3 PO 4 / H 2 SO 4 /water mixture may be used. The heat of solution produced when the concentrate dissolves may be sufflcent to evaporate the solvent. After addition of water the battery may be ready for use or may require electrical charging. The invention is also applicable to Pb-Cd batteries using H 3 PO 4  as electrolyte and alkaline Ag-Zn, Ag-Ni, Ni-Fe and Ni-Cd cells using KOH as electrolyte.
