Abstract: 1451460 Casting processes SUMITOMO METAL INDUSTRIES Ltd and AIKOH CO Ltd 9 Nov 1973 [24 March 1973 31 July 1973] 52117/73 Heading B3F [Also in Division C3] A method of casting an ingot comprises placing a float 4 within the mould prior to pouring, top pouring metal into the mould, and covering the surface of the molten metal between the float and the mould wall with a flux. The float is maintained in a central position by rods 42 having one end attached to the float and their other ends bearing against the mould walls and the flux is contained within inflammable bags (6) placed at the bottom of the mould or suspended by wires from the top of the mould prior to pouring. The float prevents splashes 21 of molten metal from reaching the mould walls and may be formed from a mixture of a refractory inorganic material, e.g. a mixture of oxides such as SiO 2 , Al 2 O 3 , Fl 2 O 3 , ZrO 2 , Cr 2 O 3 , MgO and CaO, an inorganic fibrous material, e.g. asbestos, rock wool, slag wool or kaolin, an organic fibrous material, e.g. paper, pulp or wood fibre, and a binder, e.g. a resin, or starch. Its surface may be impregnated with an aqueous solution of colloidal silica, sodium silicate or aluminium phosphate, and/or with a suspension of powders of zirconia, aluminium oxide and silica to impart fire resistance to the float.

Patent GB-530383-A (GB)
Abstract: 530,383. Calculating apparatus. MARCHANT CALCULATING MACHINE CO. June 8, 1939, No. 16830. Convention date, June 11, 1938. [Class 106 (i)] A carriage positioning mechanism, for a motor driven calculating machine having a transversely shiftable carriage, comprises a series of keys each settable to control movement of the carriage to a pre-determined operating position, a member movable in synchronism with transverse movement of the carriage, and mechanism under the joint control of the keys and the member for causing the motor to shift the carriage to the operating position corresponding to the set key. The carriage shifting mechanism is of the usual type used in the Marchant machine. The driving motor drives a gear wheel 362 which operates epicyclic gearing 1303. If the planetary gears 1315 are held stationary the wheel 1324 is driven in one direction while if the sun wheel 1327 is held stationary the gear 1324 rotates in the opposite direction. The gear 1324, through shaft 1331, bevel gears 1342, shaft 334 and gears 357, shifts the carriage through a rack 355 secured thereto. The machine is provided with a row of tabulator keys 200 which are provided with swinging members therebetween to prevent the depression of two keys at once and each key operates a lever 215 carrying a roller 216 engaging in a rocking member 280. A member 270 movable in synchromism with the shifting movement of the carriage also engages in the recesses of at least three adjacent members 280. The members 280 are provided with interlocking projections 283 and are keyed for limited rotation on shaft 285 and the member 270 is stepped so that the member 280 on the central step is positioned midway of its range of travel while those on one side of this member are situated at their extreme point of travel in one direction and those at the other side are at their extreme point of travel in the other direction. When a key 200 is depressed it rocks its particular member 280 back to middle position and thus rotates shaft 285 in a direction dependent on which side the member 280 is of the controller 270. The shaft 285 can thus regulate the action of the gearing 1303 to cause the shift mechanism to bring the carriage always towards the actuated key position. Initial depression of key 200 sets the above processes into action and further depression of key 200 operates a further lever system which starts the driving mechanism for tabulating. This latter step may be effected by a single master key after the apparatus has been set by a key 200. If no key 200 is depressed depression of the master key will cause tabulation to an extreme position. When the control member 270 moving in synchronism with the carriage reaches the depressed key and its middle step engages with the held member 280 it can be seen that the members 280 beyond this held member are pushed forward to their extreme position and the shaft 285 is restored to its middle position and tabulation ceases. Specification 229,642, [Class 106 (i)], and U.S.A. Specification 3,316,659 are referred to.

Title: Improvements relating to vehicle headlamps
IPC: B60Q1/115
Filed: 1968-11-13
Abstract: 1,241,819. Vehicle headlamps. ROBERT BOSCH G.m.b.H. 13 Nov., 1968 [17 Nov., 1967], No. 53824/68. Heading F4R. The attitude of a vehicle headlamp is adjusted by a motor acting through an eccentric pivot on the headlamp. A motor 18. is mounted on the reflector 30 of the headlamp and drives gearwheel 33 through worm 32. Gear-wheel 33 is secured to the reflector by a rod (34, Fig. 2, not shown) and has an eccentric pin 36 mounted thereon. The pin is linked 35 to a fixed pin 38 (42) secured to a screw 46 by a support 43. The link 35 is greater or less by half the total adjustment provided for the headlamp than the distance of the pin 36 from the axis 31 of the worm 32. A screw 46 provides for initial adjustment of the headlamp. Linked to pin 38 is an arm 24 pivoting at 49 on cranked member 50 which is connected to the edge 51 of the reflector. The arm 24 carries a conductive portion (25, Fig. 4, not shown) which makes electrical connection between the motor 18 and switches sensing the vehicle load. In operation, a sensor on the vehicle springs closes one of four switches according to the size of the load thereby supplying current to one of the four conductive tracks 19, 21, 22, 23 associated with the conductive portion (25) of arm 24 (Figs. 3 and 4, not shown). The motor is actuated and moves the adjusting mechanism including arm 24 until the conductive portion meets one of the non-conductive portions 26, 27, 28, 29 and thereby stops the motor. A switch may be provided to allow the adjusting mechanism to work only when the vehicle is stationary. In another embodiment (Fig. 5, not shown) a Wheatstone bridge having two variable resistors one varied by the motor and the other by the suspension, is used to adjust the inclination of the headlamp. Manual alteration of the headlamp may be achieved by a switch located on the dashboard.

Conjugated dienes free from allenic impurities are obtained by treating impure conjugated dienes with iodine and subsequently removing the iodinated allene from the mixture. The reaction is preferably carried out in the absence of oxygen, at -10‹ to +80‹ C. in daylight, fluorescent light or radiation from a mercury lamp. The iodine may be added as a solid or in organic solution. The iodinated allene may be removed by treatment with a metal alkyl, Grignard reagent or alcoholic potash, by absorption on an alumina column or by distilling off the conjugated diene. Examples describe the purification of butadiene and isoprene.
