Title: Process for removing alkali metals from hydrocarbon liquids
IPC: B01J39/00
Filed: 1955-11-23
Abstract: Alkali metals and organo-metallic compounds thereof are removed from alkali metal catalysed solution polymers of conjugated diolefin hydrocarbons by treating with an acidic cation-exchange resin.  The polymers which may be liquid may be prepared by polymerizing butadiene-1,3, optionally together with other polymerizable hydrocarbons, e.g. styrene, in solution in mineral spirits, naphtha, Varsol or heptane in the presence of alkali metal catalysts, e.g. sodium, potassium, lithium, rubidium and caesium, ether modifiers, e.g. dioxane, and activators, e.g. isopropanol.  The cation-exchange resin may contain phenolic, sulphonic, carboxylic and phosphonic acid groups, and may be prepared, e.g. by condensing formaldehyde with resorcinol and benzaldehyde-2,4-disulphonic acid.  Before treatment with the ion-exchange resin the bulk of the catalyst may be removed by electrical precipitation, centrifuging, settling or filtering and recycled, or by treatment with a water-containing clay as described in Specification 786,127.  Residual water may be removed from the polymers by treatment with acetone or dioxane.ALSO:Organo-metallic compounds of alkali metals are eliminated from liquid hydrocarbons containing such compounds by treating the liquid with an acidic cation exchange resin.  The cation exchange resin may contain phenolic, sulphonic, carboxylic and phosphonic acid groups and may be prepared, e.g. by condensing formaldehyde with resorcinol and benzaldehyde-2,4-disulphonic acid.  The liquid hydrocarbons may comprise mineral spirits, naphtha, Varsol, heptane and polymers of conjugated diolefins, e.g. butadiene-1,3, or copolymers thereof with other polymerizable hydrocarbons, e.g. styrene.  Specification 786,127, [Group IV (a)], is referred to.
Patent GB-895269-A (GB)
Title: Improvements in or relating to shift registers
IPC: G11C19/30
Filed: 1960-09-30
Abstract: 895,269. Shift registers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 30, 1960 [Oct. 2, 1959], No. 33637/60. Class 106 (1). A shift register comprises two groups of circuits, those of the first group including a photoresistor in series with an electroluminescent element arranged to form a bi-stable device, and those of the second group including a photoresistor in series with a fixed resistor. In a first embodiment a first storage element R 1  comprises a photoresistor u 1  in series with an electroluminescent element o 1  and is regarded as " ON " when the latter is activated. This irradiates the photoresistor u 1  and also a further photoresistor m 1 , causing both resistances to be greatly reduced in value. Since the resistor m 1  is in series with a fixed resistor r 1  across a voltage source V 1  the voltage at their junction is low under this condition, and when a shift pulse is applied by a generator 6, it causes conduction through a diode D 1 , thus developing a potential across an electroluminescent element l 1  and causing it to emit radiation which falls on photoresistors j 1  and u 2 . Irradiation of the latter reduces its resistance and causes an increase in voltage across its associated electroluminescent element o 2  sufficient to cause the latter to emit radiation and bring the storage element R 2  to the "ON " state. Irradiation of the photoresistor j 1  so reduces its resistance as to extinguish the parallel-connected electroluminescent element o 1  and so cause the storage element R 1  to return to the " OFF " state. In this manner information, which can be entered into the shift register by activating an electroluminescent element 7 which irradiates the photoresistor u 1  of the first stage, can be stepped through the register. It may be read out at any time by detecting the voltages at the junctions between resistors r 1  . . . r n  and m 1  . . . m n  or the radiations from the elements o 1  . . . o n . In a second embodiment the storage elements are regarded as " ON " when the incorporated electroluminescent element is not activated.

Abstract: 486,891. Preventing formation and accumulation of ice on aircraft surfaces. ECLIPSE AVIATION CORPORATION. Dec. 12, 1936, No. 34171. Convention date, Dec. 14, 1935. [Class 4] [Also in Groups XXIX and XXXVII] Mechanism for preventing formation and accumulation of ice on aircraft surfaces includes agitatable members actuated by means responsive to ice formation on the aircraft for automatically rendering such mechanism operative. As shown, flexible overshoes are inflated and deflated, e.g. in the manner described in Specification 439,284, by compressed air supplied from an engine-driven compressor 9 through an oil separator 12 and a distributor 11 driven by an electric motor. The motor is actuated on closure of a manual switch 20 and an automatic switch 28 from a battery 19. The compressor 9 is normally open to exhaust through pipes 29, 30. A solenoid-actuated valve 36 is normally held open by a spring 38 and is disposed between the pipes 29, 30. Deposition of sleet or ice on a gauze screen 71 at the mouth of a passage 49 carried on a streamlined support 52 reduces the flow of air through the passage and consequently the pressure on a disc 54. Reduction of pressure on the disc 54 which is mounted on a pivot 57 permits a spring 58 to close electrical contacts 62, 63, and, if the switch 20 is closed, the circuit through the solenoid 22. Energization of the solenoid 22 closes the valve 36. In order to prevent building up of pressure between the compressor and the valve 36, a non-return valve 46 is provided in a byepass to the valve 36. A signal lamp 24 may be provided in parallel with the solenoid 22. The spring 38 is connected to an adjustable sleeve 39.

Casting-machines; metal-pouring; castings, extracting.-Thin metal cups, for instance of lead or zinc for electric batteries, are made by connecting a mould with a fused metal reservoir to fill it, forcing in a core or plunger to press the excess of metal back into the reservoir, and then cutting off the metal above the top of the core to form the bottom of the cup. A series of moulds G are carried by a rotating table E<1> their open tops being flush with the table top. A reservoir I having an open bottom is held on the table by fixed arms K and can be moved into position over the moulds which it fills as the table rotates. Plungers H close the bottoms of the moulds in the position I and each is moved up in turn by pins H<1> engaging a stationary cam ring D to press out the excess metal and remains in this position 18, Fig. 2, until the metal is cool when it is raised to lift its cup 0 from the mculd and allow weighted extractor bars N, N<1>, Figs. 1 and 3, to pass below the cup 0 which is stripped from the plunger as it again descends. The reservoir is heated by a burner J<2> and has supply and overflow pipes J, J'.
