Title: Process for the production of valuable hydrocarbons by treatment with hydrogenating gases of high boiling carbonaceous materials, which contain high molecular substances, such as asphalts and resins
IPC: C10G47/00
Filed: 1937-04-12
Abstract: In the treatment of high-boiling liquid or fusible carbonaceous materials which contain high-molecular substances, e.g. asphalts and resins, with hydrogenating gases under pressure and at high temperature to produce oils, e.g. benzines and diesel oils free from asphalt, in which treatment fractions of higher boiling point than the products required are recycled to the reaction space, the high-molecular substances are removed before hydrogenating the mixture of initial materials and recycled fractions.  The asphaltic substances may be removed by mixing the recycled fractions with the initial material whereby the asphaltic substances are precipitated and removed by sedimentation, filtration, or centrifuging, or by subjecting the initial material to a refining hydrogenation.  The initial materials may be used as pasting agents for solid carbonaceous materials in which case the asphaltic materials are removed from the pasting oil by admixture with the recycled fraction and separation of the precipitated impurities the purified mixture being then used as pasting agent. Catalysts for the hydrogenation comprise oxides and sulphides of metals of the 5th to 7th groups preferably mixed with metalloids, metalloid halides or organic halogen compounds or organic tin compounds.  Browncoal tar freed from dust is passed with hydrogen under 200 atmos. pressure through a unit comprising three reaction vessels, in which a tungsten sulphide catalyst is arranged, with a throughput of 0,6 kgs. tar per litre catalyst per hour.  The temperature at the inlet of the first reactor is 340 DEG  C. and at the outlet 385 DEG  C. and is maintained at this level in the succeeding vessels by addition of cold hydrogen. The reaction products are separated by distillation into benzine, diesel oil and residues which latter are preheated to 375 DEG  C. and injected into the second reactor where the tar coming from the first reactor is already freed largely from asphalt.  Alternatively the residues may be injected as cooling agent at several points in the reaction space after the second half of the first reactor. Specification 484,127 is referred to.

Title: Improvements in knitting machine pattern control mechanism
IPC: D04B15/66
Filed: 1946-04-04
Abstract: 644,986. Knitting-machines. TEXTILE MACHINE WORKS. April 4, 1946, No. 10449. Convention date, April 4, 1945. [Class 74 (ii)] Additional courses may be inserted in a stocking by an arrangement in which an auxiliary pattern chain 9, triggered off by the main pattern chain 7, (a) stops the main chain, (b) starts a " course counter," which re-starts the main chain after a predetermined and variable number of additional courses; and (c) stops itself after it has controlled any narrowing operations necessary during the knitting of the additional courses. When a button on chain 7 rocks lever 23 a lever 70 is rocked (via rod 26) to hold a bluffing-wheel 74 temporarily and so cause relative movement between it and a ratchet-wheel 86 to expose the teeth of that wheel to the action of a pawl 87 operated by the main camshaft 5; whereupon the pawl commences to rack round the auxiliary pattern chain 9. A suitably placed button on chain 9 then operates one or other of two levers 106, 107 (not shown), to move a rod 61 to the right and, at the same time, through a rod 120 or 121 (not shown), to release a latch lever 115 or 116 (not shown). The rod 61, in moving, causes the rotation of a lever 51, to render inoperative the pawl racking the chain 7 and carries with it a rod 110 which rotates counter-clockwise a lever 113 to a position in which it is latched by the released lever 115 or 116. The lever 113, in so rotating, acts through a link 200 to cause the nose of a pawl 192 to push on one arm 184 of a U-shaped lever 180 and so move its other arm 182 from beneath a pawl 170 operated from the main cam-shaft. The pawl 170 is thus able to rack round a wheel 178, loose on shaft 152 and, every sixth tooth of that wheel being deep enough, to advance, at every sixth stroke, a wheel 176 fast on shaft 152. The lever 180 is carried round with the wheel 176 and stops racking after one revolution of the shaft. A counting-wheel 150 fast on the shaft 152 bears levers 208, Fig. 20, 209, Fig. 22 (not shown), which can be adjusted therearound to trip lever 115 or 116, after a predetermined part of a revolution of shaft 152, and so release lever 113 to restart the main chain 7. Meanwhile, auxiliary chain 9 continues to advance to control such shogging of cam-shaft 5 as may be required and then stops when a button on the chain swings a lever 93 counter-clockwise to permit a pawl 98 to engage bluffing-wheel 74 and cause it to move again relatively to ratchetwheel 86 to interrupt the racking thereof. The cam-shaft 5 may be shogged by the main chain 7 acting directly on a lever 27, or by the auxiliary chain 9 acting on the lever 27 through a rod 33 and lever 29; the shogging is effected through lever 35, bell-crank 38, spring 39, lever 42 and axially movable, spring-urged shaft 45 bearing a follower which coacts with one or other of cams 47, 48 on shaft 5.

Title: Process for the production of titanium
Inventor: FOLLOWS ALAN GREAVES
IPC: C22B34/12
Filed: 1959-03-26
Abstract: 870,560. Titanium production. ALLIED CHEMICAL CORPORATION. March 26, 1959, No.10675/59. Class 82(1) Titanium tetrachloride is reduced by sodium in a two stage process, in the first of which liquid sodium is dispersed on a finely divided carrier in the absence of titanium tetrachloride, the dispersion then being reacted in a separate zone with titanium chloride vapour, the whole process being carried out in an inert atmosphere. The carrier may be metallic titanium, sodium cholride, or more usually a mixture of the two as obtained by the reaction of sodium with titanium tetrachloride. The process may be operated continuously, part of the product being withdrawn and the bulk recycled as a carrier. To minimize formation of titanium subchlorides an excess of sodium of at least 15% over that stoichiometrically required for complete reduction is maintained in the reaction zone, so that the product contains at least 0.1% of sodium. The proportion of recycled carrier to the combined feed of sodium and titanium tetrachloride, which are added in stoichiometric amounts, lies within the range 25:1 to 60:1. Potassium, or an alloy of sodium and potassium, may replace sodium in the process. The withdrawn product is heated to 850-950‹ C. for 2-4 hours to convert the titanium to a stable form, and to remove some chloride, the remainder being removed by crushing and leaching. Suitable apparatus for carrying out the process is shown in Fig. 1, and a modification, in which dispersion and reaction zones are in separate vessels, in Fig. 5. Specification 828,374 is referred to.

Title: Improvement in or relating to high-frequency current spot welding machines
IPC: B23K11/10
Filed: 1953-04-20
Abstract: 733,951. Welding by pressure. DOYEN, L., and DOYEN, L. April 20, 1953 [April 19, 1952], No. 10778/53. Class 83 (4). In a high-frequency current spot - welding apparatus the pressure of the movable electrode on the fixed electrode is applied by a motor-rotated screw 3 engaging a nut 12 vertically slidable without rotation in a piston 6 with a spring 15 between the bottom of the piston and the nut, the piston carrying a support 7 for the movable electrode and being vertically slidable in a fixed cylinder 2 and the displacement of the nut relatively to the piston is used to effect stopping of the screw-driving motor. Keys 8 and 13 on the piston 6 and nut 12 engage slots 9 and 14 in the cylinder 2 and piston 6 respectively. A cap 10 closes the top of the piston so that on rotation of the screw the piston and nut descend until the moving electrode touches the work-piece. Continued rotation of the screw causes movement of the nut relatively to the piston and compression of the spring 15 to exert pressure on the work-piece. When a predetermined pressure is reached a projection 16 on the key 13 engages a nut 17 adjustably mounted on a spring-urged rod 18 to lower the rod and break a circuit between it and a contact-plate 22 connected via a compression spring 25 to a circuit for the motor and thus stop the motor. After welding the screw is rotated in the opposite sense to withdraw the movable electrode and a member 37 on the piston strikes a knob 38 to break contacts 32, 34 in the motor circuit to stop the motor when the electrode has been sufficiently raised. The two motor-controlling circuits are associated with reversing means so that the motor when re-energized rotates in a direction opposite to the previous direction.
