Title: Improvements in and relating to circuit breaker systems
IPC: H02H3/06
Filed: 1923-01-02
Abstract: 213,020. British Thomson-Houston Co., Ltd., (General Electric Co.). Jan. 2, 1923. Cut-out arrangements. - In an amtomaticallyreclosing circuit-breaker system for a load circuit supplied at a plurality of points, the circuitbreaker is re-closed by a relay controlled by the voltage across an impedance in shunt across the circuit-breaker, in conjunction with a second relay (which may be controlled by an electron discharge tube) arranged to insert an impedance in series with the shunt coil of the first relay, when the voltage across the load circuit diminishes below a predetermined value, and thereby to alter the setting of the first relay and adapt it to single source and multiple source conditions, respectively. In the arrangement shown, the reactance 13 is connected across the automatically-reclosing circuitbreaker 3 which is closed and retained closed by the coil 4 connected across the supply through the control relay 6. The relay 6 is moved to the open position by the series overload coil 8 acting on the slow-return core 10 and bv the coil 11 connected across the reactance 13. The second relay 21 is connected across the load and serves, when operated, to short-circuit a reactance 20. If, on overload, both circuit-breakers 3, 3<1> open, the voltage across the load is very small; consequently, the second relay 21 opens, inserting the reactance 20 into the circuit of coil 11 whereupon armature 12 drops closing the relay 6 and completing the reclosing circuit. If circuit-breaker 3<1> does not open, the voltage across the load remains sufficiantly high to maintain the relay 21 closed. Consequently, the current through the winding 11 is adequate to maintain the control relay open until the voltage across 12 decreases, with the increase of the load resistance, sufficiently to allow the control relay to reclose. In a modification, the coil 11 is connected in shunt with .an electron-discharge device normally shortcircuited by the relay 21 when its operating coil is de-energized. The operation is the same as in the arrangement shown in Fig. 1. Specification 1146/10 is referred to.

Title: Improvements in fluid cushion vehicles

Abstract: 1,215,372. Air-cushion vehicle. BRITISH HOVERCRAFT CORP. Ltd. 2 Jan., 1969 [3 Jan., 1968], No. 366/68. Heading B7K. An air cushion vehicle has a longitudinally extending skirt assembly, which may be either the longitudinally extending parts of the main skirt 11 or a longitudinal compartmentation skirt 13 or both, composed of a number of U- shaped segments 14, concave when viewed from the rear each segment overlapped by both arms of the segment in front. When the invention is applied to a compartmentation skirt, an upper flexible sheet 13 is attached to the structure of the vehicle and a number of segments 14 are attached thereto by attachment strips 18 and fasteners 19. The cushions are contained by a peripheral skirt which comprises an upper flexible sheet 10 with a number of segments 11 depending therefrom and additionally divided by lateral stability barriers 15. The segments of the peripheral skirt at the bow extend the full height of the skirt. The centre segment 20 is sufficiently wide to accommodate the forward end of the stability barrier 12 and the full length segments on either side are progressively narrowed to merge with the width of the dependent segments. The space between the flexible sheets 10 and 13 is supplied via ducts from fans and in turn supplies air through orifices to inflate the segments. The longitudinally extending parts of the peripheral skirt may be constructed similarly to the longitudinal barrier described. while the segments at the bow parts are turned inwardly. The segments may be attached directly to the structure.

Patent GB-587722-A (GB)
Title: Production of butadiene
IPC: C07C1/24
Filed: 1945-01-09
Abstract: 1,3-Butadiene is produced by dehydration of 1,3-butylene glycol by feeding it to a chamber containing a phosphoric acid or phosphate dehydration catalyst and continuously introducing a volatile basic material for contact with the catalyst.  Suitable basic materials are ammonia, primary, secondary or tertiary ethyl, propyl or butyl amines, aniline, pyridine or materials such as urea which decompose to give volatile bases.  They may be added to the glycol feed or introduced separately.  With aqueous ammonia solution, 28 per cent NH3, ratios of NH3 to glycol by weight may be 1 : 43-3000, generally 1 : 50-100.  Partially reacted glycol or butenol may be used in place of butylene glycol. The preferred catalyst is ammonium phosphate, including the tri-, di-or mono-ammonium salt or mixtures or decomposition products thereof, which may be suspended or dissolved in an inert organic liquid at 220-350 DEG  C. as described in Specification 584,601. Alternatively, vapour phase dehydration may be effected using the catalyst on a carrier such as "Celite" (Registered Trade Mark) or silica bonded with feldspar at 200-400, preferably 280-320 DEG  C.  Phosphoric acid or other phosphate catalysts may, however, be employed.  The process may be effected as in the aforesaid Specification with refluxing of the vapours obtained, condensation of water and partially reacted glycol, and recycling of the latter.  Examples show the effect of adding ammonia to the feed using as dehydration catalyst di-ammonium phosphate on "Celite," "Filtercell" (Registered Trade Marks), or feldspar-bonded silica, a mixture of CaHPO4 and (NH4)2HPO4, or "cyclic C18 alcohol" containing orthophosphoric acid.  An aqueous glycol containing .5 per cent urea is also dehydrated with di-ammonium phosphate on coke suspended in a wash oil.

Abstract: 583,842. Light polarizers and filters; goggles. INTERNATIONAL POLAROID CORPORATION. Jan. 19, 1942, No. 776. Convention date, Jan. 21, 1941. Drawings to Specification. [Class 97 (i)] A light polarizer and filter, suitable for use in sun-glasses, comprises a plastic layer carrying, in a single stratum, two materials, one of which substantially completely polarizes light in at least one wave band, whilst the other is -isotropic and forms a filter for light in a wave band adjacent the visible spectrum. Preferably, the polarization is effected throughout the visible spectrum, and the combination is such that uniform transmission over the visible spectrum occurs. The polarizing sheet material may be of the kinds comprising oriented polarizing particles in a transparent plastic, dyed or stained sheets of molecularly oriented linear polymeric plastics, or plastics containing oriented dichroic molecules, such as are described in Specification 548,759, [Group IV]. .As an infra-red absorbing material, Naphthol Green or Suxol Fast Green B may be incorporated in polyvinyl alcohol which is to be used for the polarizing material. For ultraviolet absorption p-hydroxybenzaldehyde may be added, this being, however, unnecessary with the crystal suspension type polarizing material, which itself absorbs ultra-violet radiation. The plastic layer may be bonded between sheets of glass, transparent plastics, or other transparent material.
