Patent GB-357630-A (GB)
IPC: C01B25/18
Filed: 1930-06-26
Abstract: 357,630. Electrolytic purification of liquids. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. June 26, 1930, No. 19463. Convention date, June 28, 1929. [Class 41.] Liquids, such as acids or salt solutions, containing dissolved inorganic impurities in very low concentrations, are purified by slow passage through perforated electrodes. In an example, phosphoric acid of strength 80-90 per cent, containing 20 mgm. per litre of arsenic trioxide and traces of heavy metal salts is passed at the rate of 4 cms. per hour through cathodes of single or multiple copper gauze of mesh 450 per sq. cm. which occupy the cross section of a trough. The anodes are of platinum wire. The cathode current density is 0À0001 amps per sq. cm., and that at the anode is between 0À01 and 0À1, e.g. 0À06, amps per sq. cm. Arsenic is deposited in spongy metallic form and is filtered off. The finer the mesh the higher the degree of purification. Small amounts of phosphorous and hypophosphorous acids contained in phosphoric acid are oxidized by passage through anodes of mesh 5000 per sq. cm with an anodic current density of 0À001 amps per sq. cm. Detailed examples are also given of the de-arsenification of sulphuric and acetic acids and also the removal of mercury from acetic acid. In these, cathodes of mesh 10000 per sq. cm. are employed. Lead may be deposited from nitric acid or nitrate solutions as metal at the cathode and as peroxide at the anode.

Abstract: 503,954. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE. July 15, 1937, No. 19630. Convention date, July 16, 1936. [Class 39 (i)] Cathode-ray tubes with intensity control of the ray have a cylindrical 'cathode 3 provided with a sleeve-like projection 5.extending beyond the circular end face in which the emissive spot 4 is inlaid. Heating of the spot 4 may be improved by heat-conducting wires inlaid therein. The projection 5 amounts to about one-half of the diameter of the cathode. The diameter of the control grid aperture is approximately equal to that of the cathode and the distance between the spot 4 and the control grid 1 is approximately the same. The anode 2 has an aperture of larger diameter than that in the grid 1. When a positive or negative bias is provided on the control grid, electrons are refracted towards the axis and all the electrons of the beam are thereby caused to pass through the dia: phragm apertures. A cross'-over in the neighbourhood of the cathode is focused on the luminous screen by a main lens system comprising the cylinder 8 and the anode 7, while the cylinders 9 and 8 constitute a condensing lens. The electrodes 9 and 2 may be connected together, the electrons then following the path 10. Alternatively electrode 9 and cathode may be connected, anode 2 being variable or connected to the cylinder 8, the rays 'then following the path 11. Suitable dimensions for the electrodes are specified.

Abstract: 968,925. Pulse modulation systems; transistor pulse circuits. PYE Ltd. May 20, 1963 [May 23, 1962], No. 19770/62. Headings H3T and H4L. In a television system an audio waveform is sampled at predetermined intervals of time to produce sound-modulated pulses which are sequentially stored and released in the same sequence from the store by means of a pulse train whose duration is less than the interline blanking period and occurs within the interline blanking period. At the transmitter, Fig. 1, an audio signal supplied via amplifier 1 is applied via gates G1, G2, G3, opened in succession by timing pulses from 3, to storage devices 4, 5, 6. Each storage device comprises a transistor TR1 through which a capacitor C is charged to a voltage proportional to the amplitude of the input signal pulse and the capacitor C will discharge only when a transistor TR2 conducts, Line synchronizing pulses from 7 are supplied to a network 8 producing three time-spaced pulses which all occur within the interline blanking period and cause transistors TR2 to conduct in succession. The resulting amplitude modulated pulses which are now compressed in time and appearing within the interline blanking period are supplied to a circuit 9 comprising a transistor TR3 with a high resistance R in its emitter circuit. This circuit acts as a constant current device so that the amplitude modulated pulses are converted into duration modulated pulses which are combined at 10 with the vision signals for transmission. The co-operating television receiver uses similar pulse storing and releasing devices.

Abstract: 421,199. Variable - speed gearing. PULS, E. F., 48, Middleton Hall Road, King's Norton, Birmingham. July 17, 1933, No. 20121. [Class 80 (ii)] Relates to variable-speed gear of the type, such as described in Specification 227,460, [Class 80 (ii)], in which two or more epicyclic gear trains are interposed between a driving and a driven member, and the engagement of any train is effected by a movable member co-operating with a cam on a shaft and connected to the ends of a brake band engaging a brake drum forming a part of the epicyclic train. According to the invention a pedal operating an engine clutch and a top-gear clutch in the gear-box is adapted when depressed to relieve or reduce the pressure exerted on the cams by the movable members connected to the brake bands so that the cam shaft can be rotated by a pre-selector lever or the like to pre-select any particular gear. A pedal 1 pivoted at 2 is connected to the engine clutch by a fork 3 and to a spindle 7 by links 5, 6. The spindle 7 carries an arm 8 to which is pivoted a stop member 16. The arm 8 has teeth 9 meshing with a worm on a shaft 11 having fingers 44 which when lifted engage brake levers 39 and relieve the cams 43 of pressure. The cam shaft 24 is geared to a spindle 22 which is connected by members 29, 30, a spring-controlled follow-up device 31 .. 35, as described in Specification 416,424, and a link 36 to a pre-selector lever. The spindle 22 carries a disc 25 having a block 28, shallow notches 26, and a deep notch 27. A cranked pawl 13 pivoted on a spindle 12 is connected by links 17, 18, to a lever 19 carrying a fork 21 for operating a top-gear clutch. The pawl 13 has a peg 14 engaging a slot 15 in the stop member 16. The operation is as follows:- When the vehicle is at rest the parts are positioned as shown, the stop 16 engaging the block 28 holding the pedal 1 depressed and the engine clutch disengaged, and the pawl 13 engaging in the first notch 26 to hold the cam shaft 24. The pre-selector lever is then moved to the gear required, and the clutch pedal is fully depressed to disengage the pawl 13 and rotate the shaft 11 so that the fingers 44 engage the brake levers 39 and move them to take the pressure off the cams 43. The springs 35 then move the link 31 so that the flat 33 thereon lies against the lever 34 and the cam shaft is rotated into the position corresponding to the gear pre-selected. The pedal 1 is then released and as the stop 16 no longer engages the block 28 the engine clutch is engaged and the pawl 13 enters a notch 26 to hold the cam shaft 24 fixed. When the mechanism is set to top-gear, the pawl 13 enters the deep notch 25 and the lever 19 then moves to engage the top-gear clutch. Specification 238,240, [Class 80 (ii)], also is referred to.
