Abstract: 1,025,589. Selective signalling. P. MILLER, and W. MILLER. Feb. 14, 1964 [March 21, 1963], No. 6316/64. Heading G4H. A burglar alarm system is characterized in that each of a plurality of units is connected to each other whereby an alarm at any of the units is displayed at every unit. As described an alarm at a unit 10, Fig. 2, results in one of a set of contacts 19 being closed whereby a relay 23 in the unit 10 and a relay 62, 95 in each of the other units 40, 70 being energized to sound and indicate the alarm at unit 10. Alarms at the other units cause similar indication. Each alarm buzzer is tuned to correspond to the location of the alarm and each can be switched out of circuit at any unit which is left unattended.

Title: Improvements in or relating to the electrolytic refining of copper
IPC: C25C1/12
Filed: 1926-03-06
Abstract: 264,116. Siemens & Halske Akt.- Ges. Jan. 6, 1926, [Convention date]. Copper and other metals, depositing.-In the refining of copper and alloys of copper with nickel, cobalt, zinc, tin, or other metals, the electrolyte consisting of cuprous chloride solution is either continuously or from time to time removed from the cell and led to a vessel where it is converted into cupric chloride by blowing in air or chlorine, the cupric chloride thereupon dissolving copper contained in the vessel in the form of granular or strips. The electrolyte is passed through a further vessel containing copper to complete the reduction of the cupric chloride before return to the cell. A small quantity of hydrochloric acid is added to the electrolyte during oxidation. A colloid such as gelatine is added to the electrolyte in order to obtain good deposits. The invention is particularly applicable to the refining of copper alloys containing considerable proportions of foreign metals, e.g. an alloy containing 70 per cent copper, 20 per cent nickel and 10 per cent zinc. The voltage may be 0.3, the current density 100 amps. per sq. metre, the electrode distance 5 cms. and the temperature 45-50‹ C. The electrolyte contains a little free hydrochloric acid and a little common salt. After the greater part of the copper has been deposited the remainder is removed from the electrolyte by chemical precipitation. The nickel and zinc or other metals are then removed successively by electrolysis or by chemical' methods.

Abstract: 520,223. Tobacco-feeding mechanism. MOLINS, D. W., BUAU, F. F., and MOLINS MACHINE CO., Ltd. July 14, 1938, Nos. 6392/40, 6393/40 and 6394/40. Divided out of 520,178. Drawings to Specification. [Class 130] In a cigarette-making or other machine in which cut tobacco is fed by a carded endless conveyer or roller, surplus tobacco is separated from the conveyer or roller by a blade adjacent to the carding of the conveyer and is deflected away from the conveyer in the same general direction of movement in a path which diverges from that of the conveyer. The tobacco thus separated may be returned by a raking device to the surface of the conveyer at a position in advance of the edge of the separating blade. The apparatus described is the same as in Specification 520,178. Specification 441,433 also is referred to in the complete Specification and Specification 385,210 in one of the Provisional Specifications.

[Class 110 (i)] The impeller comprises a disc 52 with upstanding pumping vanes extending inwards from the periphery, some of the vanes ending short of the hub while others extend inwardly to give the fluid ar initial swirl. In the embodiment shown, in an electrically-driven pump unit fixed in an aperture in the base of an aircraft petrol tank, the inner ends of the longer blades extend to the hub and terminate in deeper portions 54 to engage the incoming liquid. The impeller extends outwardly into the volute 16 to assist the movement of liquid in the volute, and the extension may have blades on the urderside also. Liquid enters the pump throngh a filter 29 and a throat-ring 21, passing a propeller 55 which beats out any entrained gas to be guided away from the incoming liquid by a guide 27 ; the shorter impeller-blades extend just within the diameter of the throat-ring aperture.

Abstract: 1379904 EVR recording system RANK ORGANISATION Ltd 8 March 1972 [15 March 1971] 6866/71 Heading H4F In a storage retrieval system using a driven storage medium on which information is stored in blocks relative to timing signals, e.g. EVR film, wherein the blocks comprise picture information frames and the timing signals field synchronizing pulses, (a) retrieval of the information is controlled by a periodic reference signal (e.g. field scanning of the flying spot scanner is triggered, 16, by a 50 Hz mains signal on line 10), (b) timing signals derived from this reference signal are incorporated into the retrieved information output signals (e.g. the field sync. pulses are derived, 18, from the mains signal), and (c) the retrieved timing signals (e.g. field pulses from the film on line 22) are phase compared, 30, with the reference signal and in response thereto the retrieval (e.g. the flying spot scanner) is additionally controlled so as to reduce the effects in the output signals of variations in drive speed of the storage medium. Phase detector 30 gives a short duration output during the field blanking period which represents in polarity and magnitude the extent of any phase error representative of film speed error. This short duration output is stored, e.g., in a box-car lengthener 32, so that it may be applied as additional field deflection to the flying spot scanner during the raster scanning of the subsequent picture frame. The effect is to vary the scanning raster position from frame to frame to compensate for film speed variations. Conventional film transport drive synchronization is effected by phase comparison 20 of the retrieved field pulses and the reference signal.

Title: Improvements relating to the treatment of synthetic fluoaluminates
IPC: C01F7/54
Filed: 1943-05-03
Abstract: 571,596. Double fluorides. ARNOLD, J. C. (Pennsylvania Salt Manufacturing Co.). May 3, 1943, No. 6927. [Class 1 (iii)] A sub-divided solid synthetic fluoaluminate, after separation from the solution in which it is prepared, is mixed with an alkaline material (in an amount of not more than 15 per cent. by weight calculated at Na2O) so that on heating (e.g. in the electrolytic production of aluminium) the treated product will not lose an appreciable quantity of fluorine. Alkali metal fluoaluminates of the cryolite or chiolite type may, for example, be so treated. The quantity of alkali used is normally below 10 per cent. and preferably 2-5 per cent. calculated as Na2O, and may be in the form of hydroxides or carbonates of the alkali metals, sodium or potassium aluminates, activated alumina, aluminium hyroxide, or calcium or magnesium oxides. The two substances may be mixed dry, as in Example 1 where synthetic cryolite is treated with soda ash, but it is preferred to have some moisture present, as in Examples 2 and 3 where moist synthetic cryolite is mixed with strong soda ash and sodium hydroxide solutions, and the product dried, e.g., at 100‹-200‹C. More alkali than is necessary for complete fixing of the volatile fluorine may be used when desired, to raise the alkali metal content of the fluoaluminate, and the product then heated at 100‹-125‹C when an alkali metal hydroxide has been employed, and at 400‹-700‹C with a carbonate. A final heating of the product obtained by any modification of the method to 400‹- 700‹C serves to ensure that later heating to these temperatures will involve no substantial ignition loss.
