Title: Improvements in or relating to numerical control systems
IPC: G05B19/418
Filed: 1964-08-25
Abstract: 1,029,362. Drilling; punching; machine tool details. SOC. PROMAT S. a.r.L. Aug. 25, 1964 [Aug. 31, 1963; July 8, 1964], No. 34812/64. Headings B3B, B3C and B3W. [Also in Division G3] A machine tool, arranged for automatic control, comprises a work-piece carriage 1 driven by a built-in hydraulic motor, not shown, moving a workpiece 100 borne by rollers 104 associated with a bed 103. The carriage is moved along a longitudinal member 101 by a pinion engaging a rack 4. A frame 105 carries a process group 110 comprising machines such as punches 135- 138 and a cutting ram 139 arranged in three planes transverse to the direction of workpieee travel. After processing, the workpiece is disposed on a delivery bench 108. The process group is hydraulically operated through a pipeline 112 from an hydraulic station 106 and the group may include drills. The carriage motor is fed from a control station 107 through lines 61, 62 supported, to allow free carriage movement, by a cable-bearing chain 111. The carriage movement is determined photo-electrically by a photo-diode scanning holes in the motor pinion to generate electric pulses which are fed along a cable 127 to the control station. At the control station are provided counters, equal to the number of transverse planes, and controllers, equal to the number of machines, which are interconnected through display panels. The display panels comprise cross-bar selectors having sliding markers whereby any counting stage output of a counter can be connected to a controller. The counters receive the movement pulses in parallel and count from a reset value dependent on the displacement of the transverse planes. At counts selected by the markers a system of trigger circuits and Or-gates (see Division G3), causes the carriage to be slowed, then stopped and the machine associated with the controller actuated through an electro-hydraulic valve. When all the simultaneously selected operations have been completed in the transverse plane, the carriage is released and moves at fast or slow speed to the next operating position.

Patent GB-472463-A (GB)
Title: Improvements relating to motor fuels
IPC: C10G50/00
Filed: 1935-12-18
Abstract: Gases containing isobutene are treated in the liquid phase with 50--65 per cent sulphuric acid, the gases and acid being cooled before and during the treatment so that the temperature does not exceed 40 DEG  C., and the treatment continuing until the specific gravity of the acid liquor is reduced to a degree substantially short of that at which all the water has been used, the resulting acid liquor after settlement and separation being heated to yield a mixture of di- and tri-isobutene which separates as a supernatant layer and is freed from acid and re-distilled.  The product, if desired after hydrogenation, is used as a motor spirit or blended with other spirit or butane.  A liquid C4 fraction of boiling range -10 to 0 DEG  C., containing butenes, butane, and butadiene may be freed from sulphur and mixed with the acid for a period of 15 mins. or less with 60 per cent acid, or 45 mins. with 55 per cent acid. The same acid may be used for a number of batches, the time of contact being gradually increased. Alternatively counter-current washing apparatus may be used until the acid liquor has a specific gravity of 1,2--1,1.  The hydrocarbon may previously be diluted with a petroleum distillate, e.g. of boiling range 40--80 DEG  C., or crude di-isobutene.  The acid liquor after separation is heated at 60--110, preferably about 90 DEG  C., to decompose the butyl alcohol to di- and tri-isobutene, e.g. in the proportion 80 : 20, B.P. 100--185 DEG  C.  Lower temperatures, e.g. 68 DEG  C. with or without increased pressure may be used, or higher temperatures such as 120 DEG  C. with increased pressure. Dilution with fresh acid reduces gas loss during heating.  The product is soda washed and re-distilled and may be hydrogenated with a nickel catalyst at 180--200 DEG  C.  The acid liquor may be fed continuously to the central zone of a heated polymerization vessel having draw off pipes at top and bottom through which the polymer and acid are withdrawn respectively.  The latter is cooled and re-used, while the polymer may be washed with water or aqueous acid to remove dissolved butyl alcohol.  In an example, a C4 cut containing 20,5 per cent isobutene is treated in a counter-current mixer having two pairs of mixing and separating vessels with acid of specific gravity 1,465, the inlet temperatures of hydrocarbon and acid being 1 and 28 DEG  C., respectively, and time of contact 25 mins. in each stage. Temperature rises to 33 DEG C., the acid layers forming having specific gravities of 1,37 and 1,20.  Polymerizing temperature is 60 DEG  C., and the pressure on the plant 35 lb./in<2>. Further examples using somewhat different reaction conditions are given.ALSO:Gases containing isobutene are treated in the liquid phase with 50--65 per cent sulphuric acid at a temperature not exceeding 40 DEG  C., the resulting acid liquor being heated to yield di- and tri-isobutene.  The product is freed from acid and re-distilled, and is used if desired, after hydrogenation, as a motor, spirit, or blended with other spirit or butane.

Title: Method for controlling carbon black furnaces
IPC: G01N25/18
Filed: 1966-08-05
Abstract: <PICT:1122909/C1/1> In a carbon black furnace of the type in which fuel, hydrocarbon make stock and air are reacted, the supply of air being insufficient for complete combustion, samples of the combustion gases are taken continuously and their thermal conductivity compared with a reference nitrogen gas and any variation from the correct setting causes a signal to be transmitted to a valve to maintain the correct ratio of fuel &c. for producing carbon black of the desired properties. In one embodiment, Fig. 1, a combustion chamber 13 having gas burners 20, a feed pipe 21 for the hydrocarbon make stock and an air supply 25 to a plenum 19 is arranged above a reaction chamber 14 from which the carbon black passes via a conduit 15 to a collection system.  A manually operated valve 27 controls the air supply and a valve 31 in a by-pass 28 is controlled by the signal dependent upon changes in the thermal conductivity of the gas sample.  A sampling probe 32 extends into the chamber 14 and a sample of combustion gas passes through a cyclone separator 45, a filter 49 to a gas flow measuring device 52 and then to the thermal conductivity cell 55 connected to a D.C. source 56.  Changes in an electric signal produced in the cell 55 pass to a controller 69 which produces a pneumatic signal in line 71 whereby the valve 31 is operated.  The valve 31 may control the total air feed if desired or alternatively may control a by-pass in the oil supply or may control the total oil supply.  In a further embodiment the valve 31 may control the gas supply by being positioned in a by-pass line or in the main supply line.  The control can be applied to any two of the three components fed to the furnace.

Patent GB-814934-A (GB)
Title: Method for producing melamine
IPC: B01J3/04
Filed: 1957-11-12
Abstract: Melamine is produced by reacting dicyandiamide, previously heated to between 100 DEG  C. and its melting point, with gaseous ammonia under pressure, the pressure of ammonia being maintained throughout the reaction so as to be at least 50 kg./sq. cm. at the end of the reaction, this pressure being maintained during the cooling of the reaction product as long as its temperature is higher than about 250 DEG  C.  Preferably the pressure is maintained so as to reach about 80 kg./sq. cm. when the temperature of the melamine reaches 350 DEG C.  It is advantageous for the dicyandiamide and the reaction vessel to be pre-heated as uniformly as possible, so that no point of the reaction mixture is at a temperature lower than the condensation temperature of ammonia under the operating pressure.  It is also desirable that the size of the reaction vessel be such that the heat of reaction is dispersed without raising the temperature of the melamine substantially above 350 DEG  C.  Auxiliary compression means may be employed for attaining the final pressure of 50 kg./sq. cm. The reaction may be effected intermittently, e.g. inside a digester which may be enclosed in a container, the cooling being carried out in the digester, or continuously, e.g. by passing pre-heated dicyandiamide and gaseous ammonia into a first closed chamber, transferring the product in a liquid state into a second closed chamber, and feeding the product continuously or periodically into a third closed chamber where it is cooled.  If desired, the final melamine product may be purified by recrystallization from hot water. The process is described with reference to drawings (not shown) illustrating the batchwise and continuous procedures.
