Patent GB-889383-A (GB)
Title: Improvements in or relating to coupling devices
Inventor: VALENTINE NEVILLE
IPC: H01R13/66
Filed: 1957-05-23
Abstract: 889,383. Operating single-indication receivers. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 20, 1958 [May 23, 1957], No. 16462/57. Class 118. [Also in Group XXXVI] A coupling part for fluid hose or, as shown, a plug for a cable 3, incorporates a variable impedance which is adapted to provide a remote indication as to whether the part is attached to or detached from its co.operating coupling part. The plug body 15 is adapted to be secured to a co-operating socket 1 by a screw-threaded sleeve 17 enclosing ring-shaped housings 9; 10 carrying respectively an electromagnet 4 and an armature 11 and surrounding the rear end of the plug body. The coil of the electromagnet is connected in an indicator circuit by leads 6, 7 and is wound on an E-shaped core 5. In the disconnected state of the coupling, springs 12, 13 urge the housings together so that the armature 11 bridges the ends of the core 5, the spring 13 being retained in the sleeve 17 by a stop plate 19 and circlip 20. As the coupling parts are connected the end of socket 1 presses the housing 10, and hence the armature 11, away from the core 5 against spring 13 and through the intermediary of an inner sleeve 23. The impedance of coil 4 is thus decreased and an increase of current takes place in the indicator circuit, such increase taking place after the coupling contacts have engaged each other and being employed either to operate a switch controlling the supply to cable 3 or to give an indication that the coupling is made. As the coupling parts are disconnected, the core 5 and armature 11 engage each other and a corresponding decrease in current in the indicator circuit takes place before the coupling contacts can be separated.

Title: Improvements in or relating to polymer compositions and articles
IPC: C08L33/20
Filed: 1956-05-31
Abstract: A composition comprises a stable dispersion of viscose and "acrylonitrile polymer," the latter covering not only polymers of acrylonitrile itself but also copolymers of it with one or more monomers, e.g. ethylenically unsaturated monomers with the proviso that acrylonitrile units predominate in the copolymer chain.  Small quantities of other materials, monomeric or polymeric, may be added to the acrylonitrile polymer.  Preferably, the composition comprises a stable aqueous dispersion containing up to 25 per cent by weight of polyacrylonitrile with viscose containing up to about 7.5 per cent by weight of free caustic alkali.  Agglomeration of the disperse phase of the polymer dispersion can be avoided by decationizing, using a cation exchange resin with subsequent adjustment of the pH to 9-10 with ammonium hydroxide.  The described compositions may be wet spun to form filaments or films.  In an example, viscose containing 2.4 per cent by weight excess caustic alkali, 5 per cent by weight cellulose and having a degree of xanthation of 0.62 is stirred into a polymer dispersion containing 20 per cent by weight polyacrylonitrile.  After deaerating the dispersion is extended into an aqueous bath containing sulphuric acid, zinc and sodium sulphates and the filaments formed passed into another bath containing calcium thiocyanate solution.  Finally' the filaments are washed and stretched.

Filed: 1967-04-13
Abstract: 1,176,949. Electroluminescence. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 28 March, 1968 [13 April, 1967], No. 17095/67. Heading C4S. [Also in Division H1] An electroluminescent device of variable or restricted light-emitting area comprises two regions defining a junction across which chargecarriers can be injected to produce luminescence by the application of a first unidirectional voltage between a first electrode on the first region and a second electrode on the second region. The first region also carries a third electrode, and a second unidirectional voltage, of the same polarity as the first voltage, applied between the third and second electrodes produces a potential distribution in the first region which controls the location and area of the junction across which injection occurs to cause luminescence. The second voltage may be variable, and may be less than the cut-off voltage required to produce luminescence. The first voltage must, in this case, be greater than the cut-off voltage. A particular embodiment comprises a SiC body containing a PN junction, with a Mo electrode (second electrode) brazed to the P region by an Au/Ta/A1 alloy and two spaced Au/Ta/Sb electrodes (first and third electrodes) alloyed to the N region. A PN hetero junction may alternatively be incorporated in the device. In a further form a metal or semi-conductive layer is applied to an electroluminescent phosphor, the emitted light being transmitted either through the face of the former layer or through a part of the edge of the device. The body may be ring-shaped with the first and third electrodes located on opposite ends of a diameter, or may be disc-shaped with a central first (third) electrode and a peripheral annular third (first) electrode. Two or more third electrodes may be provided, carrying either the same or different control voltages.

Title: Improvements in or relating to the reforming of petroleum naphthas
Inventor: POTTER EDWARD BARRIE VERNON
IPC: C10G59/02
Filed: 1957-05-31
Abstract: A naphtha is catalytically reformed by contacting with a platinum catalyst in the presence of hydrogen under a pressure of 100-300 p.s.i.g. to cause aromatization, separating a heavy fraction boiling above 230 DEG  F. from the liquid reformate and catalytically reforming this heavy fraction in the presence of hydrogen and a platinum or molybdena catalyst under a pressure of 300-800 p.s.i.g. to cause dealkylation.  The feed is preferably a C5+ naphtha boiling below 480 DEG  F. and is treated in the first stage with a fixed or fluidized bed of catalyst containing 0.2-2% of platinum on alcoholate alumina, activated alumina, silica gel, zinc alumina or zinc alumina spinel, and containing if desired zinc, calcium oxide, ceria or potassia.  Suitable conditions are 800-1000 DEG  F. with 2000-6000 SCF of added hydrogen per barrel of feed.  The liquid reformate is separated from gaseous effluent which may be recycled or used in the second reforming.  The heavy reformate led to the second reforming preferably boils between 230 DEG  and 400 DEG  F. and may be mixed with fresh naphtha if desired; the light reformate is removed as product.  Conditions in the second reforming may be 880-1100 DEG  F., with 2000-6000 SCF of added hydrogen per barrel.  In this stage hydrogen is consumed and light hydrocarbons formed and the normally gaseous effluent cannot be used as recycle gas without at least partial removal of light hydrocarbons.  The product may be fractionated, if desired in the same fractionator as the reformate from the first stage, product boiling below 250 DEG  F. being removed as product and higher boiling material being recycled to the second stage.
