Title: An improved machine for filling bottles or other receptacles by suction
IPC: B65B1/16
Filed: 1936-02-08
Abstract: 470,410. Filling bottles &c. BROADHURST, S. F., and ALBRO FILLERS & ENGINEERING CO., Ltd. Feb. 8, 1936, No. 3938. [Class 125 (ii)] In a suction bottling- machine having an interceptor between the filling head and the pump, a non - return valve is arranged between the filling head and the interceptor, and a second non- return valve arranged between the interceptor and and the main supply container, a control valve being provided by means of which, after the filling operation, compressed air is supplied to the interceptor to blow the trapped material through the second non-return valve into the main supply container. The control valve is preferably arranged to have two positions, in one of which the receptacle is filled under suction, and in the other, the interceptor is cleared. A machine adapted for use with powder comprises a supply 3, Fig. 1, from which powder passes to the filling head 1 and receptacle 69 mounted on a platform 4 connected to the cylinder 7 so that the table can be raised pneumatically. An air pump 11 has a suction chamber 13 and a pressure chamber 15. With the control valve 18 in the position shown, see also Fig. 12, suction is applied to the port 22 and cylinder 7 to raise the bottle into contact with the filling head 1, and to the port 19, pressure reducing valve 47, powder trap 43, and filling head 1. The filling head, Fig. 7, has a rubber cushion 30, a powder supply tube 36, and a filter 37 leading to passages 40, 41. By applying suction at 41, as above, the air bottle is partly evacuated and powder drawn in. When the bottle is full, the control valve 18 is rotated, by foot pedal, to the position shown in Fig. 11, whereby ports 21 and 22 are opened to atmosphere so that the vacuum is broken and the bottle lowered, and pressure is applied to port 19, pipes 64, 65 to the powder trap 43. The trap 43, Fig. 6, contains a filter 44 and non-return valve 42, so that air pressure at 45 causes any trapped powder to pass via 46 through the non-return valve 63 into the supply 3 ; the excess air passes through the filter 61 and 3-way cock 60 to the atmosphere. The supply 3 is provided with a mechanical agitator, and may be replenished by dipping the pipe 71 into a bulk supply, turning the cock 60 through 90‹ and operating the control valve 18 to fill a bottle ; a partial vacuum will thereby be created in 3 and powder drawn in through 71 ; a vacuum relief valve 72 prevents the partial vacuum in 3 becoming too high. The pressure reducing valve 47, Fig. 5, is adjustable by the hand wheel 52. A safety valve 70 is provided on the pressure chamber 15.

Title: A method of rolling stock in a continuous rolling mill for division into equal lengths without a reminder, and apparatus for performing the same
IPC: B21B37/70
Filed: 1963-02-01
Abstract: 1,009,238. Rolling. SCHLOEMANN A.G. Feb. 1, 1963 [Feb. 16, 1962], No. 4172/63. Heading B3M. In a method of rolling stock to a definite finished length in a finishing mill the roll clearance and rolling speed of the final stand are determined from the speed of draw-in of the stock into the finishing mill, its incoming length, and its desired final length. Before a length of stock 1 enters finishing stands 2-5 its length is measured by heads 7 and 8, and its speed by a roller 13. These values, together with the required final length of the stock, as indicated by a reference generator 15, are fed to a computer 11 whose output gives the desired speed of the stock leaving stand 5. The desired value can be displayed to allow manual control of the speed of stand 5, or it can be compared at 21 with the actual speed, measured by a roller 14, and the difference fed to a controller 24 which determines the screwdown of the stand. A loop controller, 26, which is sensitive to a change in the size of the loop, reacts to a change in screwdown in stand 5 and changes the roll speed appropriately through a motor 27. The rollers 13 and 14 may be replaced by photo-electric sensing devices. Since the above system only operates when the front of the stock 1 has reached the roller 14, the leading end of the stock has no connection made to it. To correct this shortcoming, a memory device 30, which has fed to it the roll adjustments for the previous two lengths of stock rolled, passes a value to a proportionalizing computer 32 which in turn actuates a roll adjuster 24.

Title: Improvements in or relating to the purification of titanium tetrachloride
Inventor: MAS ROBERT JEAN
IPC: C22B34/12
Filed: 1959-02-09
Abstract: Titanium tetrachloride "sludge", left as a still residue when crude tetrachloride is distilled in the presence of purifying agents, is contacted with hot chlorination gases, produced by the chlorination, in the presence of a reducing agent, of a titanium ore with elemental chlorine.  The titanium tetrachloride is vaporized and the normally solid constituents of the sludge are deposited in the dry state and separated from the tetrachloride vapours.  The sludges, preferably homogenized, may be sprayed into the hot gases as they pass through a tuyere or through a cooling chamber.  Additional cooling may be effected by injecting crude titanium tetrachloride into the hot gases in amount sufficient to bring normally solid constituents to settle out, as in Specification 679,537.  Indirect cooling may also be employed. The sludges to be treated may result from distillation in the presence of mineral absorbing agents, sulphur, sulphides, oils and soaps, metals and metal hydrides.  According to Examples (1) rutile chlorination gases were passed through cooling chambers where the temperature was reduced from 970 to 550 DEG C., then after cooling to 170 DEG C. by recycled tail gas, through electrostatic precipitators.  Titanium tetrachloride was thereafter condensed by contact with cold liquid tetrachloride and the resulting crude vanadium oxychloride-containing condensate was distilled with 0.3% mineral oil.  A substantial pure titanium tetrachloride was recovered overhead and the still residue sludge was sprayed into the cooling chambers to reduce the gas temperature from 550 to 500 DEG C. before recycle of the tail gas.  (2) Hot chlorination gases were cooled from 600 to 180 DEG C. by passage through a cooling chamber into which crude titanium tetrachloride and a purification sludge were fed.  The sludge resulted either from distillation in the presence of a mineral oil or from refluxing titanium tetrachloride with minor amounts of sodium stearate and antimony sulphide.  Specification 796,967 also is referred to.
