IPC: F02M41/12
Filed: 1962-10-02
Abstract: 1,015,678. Fuel injection pumps. R. BOSCH G.m.b.H. Oct. 2, 1962 [Oct. 13, 1961], No. 37258/62. Heading F1A. A rotary and reciprocating piston 7 having a spill port 32 communicating with the pump chamber and controlled by a valve 31 and a distributing port 45, is slidably coupled for rotation with a valve disc 21 which controls inlet ports 27 in a disc 22 to the pump chamber. The pump is fed by a pump 41 and during the initial part of the suction stroke fuel flows through the valve 31 back to the reservoir removing bubbles from the working chamber. Delivery is terminated when the valve 31 clears the port 32 on the delivery stroke; alternatively the port 32 may be repositioned as at 32<SP>1</SP> so that output is controlled on the suction stroke only.

Patent GB-1124204-A (GB)
Title: Process for working up coal tar pitch
IPC: C10C3/00
Filed: 1966-08-23
Abstract: Coal tar pitch is treated by being mixed at elevated temperature with a petroleum fraction or solvent extract boiling in the range 250 DEG to 450 DEG  C., e.g. a furfurol extract, the undissolved sediment being separated from the mixture and, if desired, the solution remaining being distilled.  The mixture may be heated in stages (temperatures of 180 DEG  to 380 DEG  C. are mentioned) with intermediate and final cooling, and separation may likewise proceed in stages. The solution is distilled and preferably cracked at temperatures up to 450 DEG  C. to produce unspecified ores, a coke-like residue remaining. Distillation is at atmospheric pressure and may be carried out in different temperature stages. The sediment from the separation stage may be extracted, e.g. with petroleum fractions and extracts, the solutions obtained may be distilled and the insoluble components removed from the solution.  Four specific examples are described, and in one a mixture of pitch and extract after heating to 180 DEG  C. and cooling is mixed with a heavy fuel oil, reheated and cooled, before separation.

IPC: C01D3/22
Filed: 1959-11-10
Abstract: <PICT:0911130/III/1> Flake salt is produced by subjecting moist granular salt, e.g. containing 0,005 to 0,5% by weight of moisture and the majority by weight of the particles, preferably all, having a particle size of 20 to 200 Tyler mesh, to a compacting action under pressure and preferably at a temperature in excess of ambient temperature to form a sheet having a thickness less than 0,03 of an inch, cooling the formed sheet slowly and then breaking up the sheet into flakes.  The moisture in the granular salt may be augmented.  In the figure, finely ground ordinary granular salt is delivered from a measuring device 1 e.g. by gravity, to screw conveyer 3 provided with steam jacket 4, and water is sprayed into the salt at 7.  The salt thus heated to 200 DEG  to 270 DEG F. is then taken via a vibrating feeder-spreader 8 to rolls 9, the rollers of which may rotate at the same or different speeds and are preferably heated.  The sheet of compacted salt formed is placed on a conveyer 10 for at least 15 minutes prior to being discharged on to corrugated roll crusher 11 in which the sheet of salt is broken into small fragments (flakes).

Abstract: 948,677. Forging presses. B. & S. MASSEY & SONS Ltd., J. FOSTER, and P. BALL. Nov. 12, 1962 [Nov. 1, 1961], No. 39041/61. Heading B3H. In a multi-stage forging press the metal blanks are transferred between dies 14 by pairs of gripping fingers 53, Fig. 5. Three hot forging and one final trimming operation are performed on a flat blank cut from metal bar and the blank is turned through 90 degrees during transfer between the first two stages. The transfer fingers project inwardly from two parallel hollow box-section frames 16, Fig. 3, pivoted at their ends to side members 31 which are mounted on one of the arms 34 of bellcrank levers rocking about shafts 32. The other arms 33 are connected by links 36 to a lever 35 actuated by an eccentric shaft 38. Rotation of the latter causes raising and lowering of the frames 16 and simultaneously they are moved longitudinally by a cam 30 on a shaft 40, engaging a follower 43 connected to one of the arms and biased by a pneumatic piston 92. Both shafts 38, 40 are chain-driven from the eccentric shaft 30 of the press. The frames 16 are also moved towards and away from each other, for closing upon a workpiece, by hydraulic cylinders 45, Fig. 3, supplied by a cam-driven pump operated from the eccentric shaft 30 of the press. Each pair of fingers, Fig. 5, comprises a lower non-pivotal finger detachably mounted on spigot 52, and an upper finger 53 detachably mounted on a spigot 61 pivoted at 72 and connected to a push-rod 70 loaded by a spring 73 which biases the fingers to closed position. They are opened by a cam 84 on cam-shaft 20. Each of the latter is driven through universal couplings 21, 24 and a splined-rod 22, Fig. 3, from gear-boxes 26 whose input shafts 27 are chain-driven from the eccentric shaft 30 of the press. Both gear-boxes are adjustable towards and away from each other by a lead screw operated by hand wheel 49, to suit different sizes of dies. The fingers used for turning the workpiece during transfer are mounted within a sleeve 67, Fig. 5, supported in bearings 68 within frame 16. The sleeve is coupled by a link to the fixed press bolster 11 whereby it is rotated automatically during longitudinal transfer movement of the frames. Other fingers are described, Fig. 4 (not shown), which transfer the workpiece without turning it. Low-pressure air is supplied to the interior of the hollow frames 16 for cooling and to prevent entry of scale. Heatdeflector plates are also interposed between the frames and the dies. The starting blanks are supplied to the first die by a conveyer or along a shoot.

The apparatus utilizes the fact that the decimal digits c i  of the product are of the form where (1) if a i  is even p i  = 0 and if a i  is odd p i  = 5 and (2) u i  is obtained by division of a i  by 2 (rounded down). In the embodiment described AND gates 2, 7 are enabled at bit times representing digits of weight 2<SP>0</SP> and 2<SP>2</SP> so that if the first bit of each decimal digit is a "1" representing an odd digit, serial pulses representing 5 are fed to one input 10 of the adder 11. The second input u<SP>i-1</SP> to the adder 5 is derived by a total delay of three bits effected by the bi-stables 3, 5, 6 which represent a delay of one digit time with simultaneous division by 2 and rounding down of each digit.

A 5-30 wt. per cent solution of pulverized coal 10 is formed in a recycle stream 16 of molten salt (e.g. comprising mixed lithium, sodium, potassium and magnesium chlorides) and contacted with steam 22 for 0À2-5 sec. at a salt temperature of 300-600‹ C. and 1-25 atmospheres absolute to produce an overhead stream 29 comprising coal-derived hydrocarbons. The stream 29 can be subjected to a shift reaction at 31 and then cooled at 32 to condense a hydrocarbon fraction, which can be fractionated at 34, from the gaseous portion which can be further separated at 42 and 44. The molten salt stream 50 containing 2-10 wt. per cent of the remaining less volatile 15-50% of the coal is treated with air 52 to oxidize the remaining coal components and heat the salt to 600-1000‹C. Heat energy is obtained from the salt leaving the combustion zone 30 by direct heat exchange with a liquid metal (e.g. lead) at 72 which in turn is used to heat steam by direct heat exchange at 78.
