Title: Casting metals

IPC: B22C9/04
Filed: 1966-01-17
Abstract: 1,132,361. Casting processes. MONSANTO CHEMICALS Ltd. 19 Dec., 1966 [17 Jan., 1966], No. 2116/66. Heading B3F. [Also in Division C3] A metal casting is made by pouring molten metal into a ceramic shell mould, the casting and shell then being allowed to cool while surrounded by particulate active carbon. The metal may be poured into a mould surrounded by the C. The C may have specific surface area of at least 500 m<SP>2</SP>g<SP>-1</SP>, residual volatile content of not more than 5% wt, and particle size 30-200 B.S.S. The C may be produced by carbonization and activation of bone, wood, peat, or nut shells, e.g. coconut shells. The C may be fluidized durring immersion of the shell. The C may be a component of a mixture with one or more particulate refractory solids, the C forming at least 5% wt; refractory solids may be e.g. molochite, zircon sand, or metal ball-shot. The shell mould may be produced conventionally, e.g. using coatings of powdered refractory, e.g. sillimanite, in a liquid binding agent derived from ethyl silicate, with intermediate stucco layers. The mould is preferably immersed in the C immediately on withdrawal from the firing furnace, and the metal poured in without delay. The C combines with O 2  in the vicinity of the mould, thus preventing access of O 2  to the metal. The metal may be low-carbon steel, low-alloy steel, or high-carbon, high-alloy steel.
Patent GB-943648-A (GB)
Title: Device which automatically stops a reversing strip cold rolling mill when the rolled strip is approaching its end
IPC: B21B37/54
Filed: 1961-01-19
Abstract: 943,648. Automatic speed control. ZAVODY V. I. LENINA PLZEN, NARODNI PODNIK. Jan. 19, 1961 [Jan. 21, 1960], No. 2138/61. Heading G3R. [Also in Division H2] The D.C. drive motor 4 of a reversing cold strip rolling mill is caused to decelerate uniformly to rest as the strip approaches its end. The motor armature is supplied from a generator or rectifier 6 which is controlled by the voltage from a tachogenerator 8 compared with a reference derived from a potentiometer 9. For stopping purposes this potentiometer is moved by a servometer 10 supplied from a magnetic amplifier 11 having a  control winding 12 which is energized when the arms of two selector switches 17, 18 are coincident, by the difference between a voltage proportional to strip speed from a tacho-generator 14 and another voltage derived from a rotary potentiometer 15 driven by the strip reel 2. The potentiometer 15 is wound so that its output voltage is proportional to the square root of the strip length wound on the reel 2 and it is shown that this results in the deceleration being constant. The strip is first run through the mill in one direction and stopped manually, during which selector 17 will have been advanced a number of steps corresponding to complete revolutions of rotary potentiometer 15. The mill is then reversed, when the other selector 18 advances until it is coincident with 17 and the circuit through control winding 12 is completed. The output of potentiometer 15 initially exceeds that of the tacho-generator 14 and the polarity is such that a rectifier 13 blocks, so that the mill runs on unchecked. However, as soon as the decreasing voltage from 15 drops below that of 14 the control winding of the magnetic amplifier is energized in a way to cause the servometer 10 to move the potentiometer 9 in a direction to decrease the speed of the mill motor 4. The decrease will continue until the output of 15 is zero, which will occur when a similar length of strip has been rolled as that during the original, manually controlled, operation. The unrolled ends of the strip are increased in length after each pass (to ensure they do not enter the rolls) by providing a successively increasing biasing voltage from a tapped potentiometer 19. The potentiometer 15 is reset to zero  when required by de-energizing a magnetic coupling 29 and energizing a second one 30, at the same time running a resetting motor 33. The selector 17 and 18 are driven electromagnetedly by a pulsing switch coupled to the rotary potentiometer 15 and the circuit includes a time delay cut-out which operates if the reel stops with the pulsing contacts closed, and the arrangement is duplicated for passes in the reverse direction.

Abstract: 538,617. Steam' superheaters. SUPERHEATER CO., Ltd. (Campagnie des Surchaurfeurs.). Feb. 7, 1940, Nos. 2367 and 8628. [Class 123 (iii)] To maintain the super-heated steam supply to the engine of a locomotive at constant temperature, the super-heater is designed to give a pre-determined minimum steam temperature when the locomotive is running under conditions least favourable to super-heating, and under other conditions, part of the steam in the superheated steam pipe 3a, Fig. 1, is directed by a valve 5 through a de-super-heater 15 in the boiler water and then returned and mixed with the other part of the steam from the steam pipe before passing to the engine valve chest. The valve comprises a member 25, Fig. 4, having spaced arms 29, 30 and rotated by a thermostat 31 in the path of the mixed steam. The arm 30 closes the entrance 13 to the pipe 15 leading to the de-super-heater and allows all the steam to flow from the pipe 3a through the valve and an annular space 11 around a sleeve 6 to the engine supply pipe 12. The arm 29 directs part of the steam into the de-super-heater from which it returns through a pipe 16. -The de-super-heater steam may be sprayed into the super-heater steam. In further modifications, the steam is de-super-heated by a heat exchanger between pipes 3a and 12. Boiler water is circulated through the de-super-heater and either the water or steam flow through the heat exchanger is regulated to control the final super-heat.

The derivative may be de-oiled by separation from an ethylene dichloride solution.ALSO:A paraffin or microcrystalline wax derivative substantially non-reactive with urea, which has been isolated from at least a portion of the urea-reactive constituents of the wax, is used for coating or laminating base sheets.  The wax is melted at 200 DEG  F., excess urea and 2 per cent. water are added, and the mixture stirred and held at 170-190 DEG  F. until the urea-wax complex separates as a white precipitate. The mixture is filtered and the resultant derivative consisting of branched chain paraffins and cyclic compounds substantially free from normal paraffins is heated to drive off water.  The derivative may be de-oiled by separation from an ethylene dichloride solution. Alternatively, the paraffin or microcrystalline wax may be treated with urea to remove only part of the reactive components.  The non-reactive derivative alone, or added as a minor proportion to paraffin wax, which may have no components melting in excess of 150 DEG  F. and may be de-oiled, may have modifying agents, e.g. polyisobutylene, rubber, polyethylene, or butyl rubber, added thereto.

Sulphonic acids; dye preparations. - The products obtained by oxidizing sulphite cellulose pitch with aqueous nitric acid, hydrogen peroxide, chromic acid, permanganates, air in the presence of ammoniacal copper sulphate &c. are used in the production of dyestuff preparations, both as powder and as paste, the effect of their presence being to keep the dyestuff in easily dispersible form and to prevent coagulation and settling of dyestuff pastes. When added to an already dispersed dyestuff paste they enable the paste to be dried at moderately high temperatures to a powder which retains its power to disperse readily in water. In an example, an aqueous paste of 1-methylaminoanthraquinone is mixed with a solution of the oxidation product of cellulose sulphite pitch which has been made alkaline and filtered. The product is dried, preferably after the addition of a small quantity of sodium hydroxide solution, and powdered.
