Title: Metal impurity removal from gaseous stream
Inventor: CENTA TIM
IPC: B01D53/38
Filed: 2009-12-17
Abstract: A method and apparatus for the removal of sodium magnesium, iron, nickel and chromium from a gaseous stream wherein the apparatus or trap comprises an unlined pipe 136 which is at least 45.7 cm (18 inches) long, a heated pipe 114, a cooled pipe 109 connected to the heated pipe and an injection point 101. In use, a gaseous stream containing sodium is conducted through the unlined pipe 136 and a neutralizing agent is injected into the gaseous stream at an injection point 101, wherein the injection point is located at a point where the sodium is in at least a partially condensed state. The gaseous stream is then conducted through the heated pipe 114 and the cooled pipe 109. The neutralizing agent maybe carbon dioxide (CO2), water, steam or nitrous oxide (NO2). The trap is connected to a carbonization furnace and the gaseous stream results from the sublimation of sodium and other impurities during a carbon fibre production process. The removal of these impurities prevents fouling and corrosion of downstream components.

Abstract: 472,416. Copying and reproducing mechanism. I. M. K. SYNDICATE, Ltd., and BYRON, D. H. April 7, 1936, No. 10248. [Class 83 (iii)] [Also in Groups XX and XXIII] A lens to be used in optical systems at or near a real image to direct the rays in the direction desired is made in the form of a large number of zones lying substantially in one plane. The zones may be separate from one another, forming a series of concentric rings or they may form a continuous spiral. The lens may be formed, as shown in Fig. 1, by cutting by means of a lathe a flat spiral in a metal disc b, using a tool c pivoted at d to a telescopic arm e pivoting about a point f on the axis of the lathe, the distance from the pivot f to the surface a being equal to the radius of curvature of the lens surface. The metal plate so cut is used for impressing a sheet of suitable material to be used as the lens. The lens may alternatively be formed as shown in Fig. 2, by placing the blank a on a floor and placing over it a ring b which can rotate in its own plane on supports c. The ring b has a diametral bridge d on which is mounted a motor e and grinding wheel f, or cutter, the inclination of which is controlled by an arm g passing through a ball-and-socket j supported by rods k.

Title: Improvements in and relating to electric motor control systems
IPC: B21B37/60
Filed: 1940-06-15
Abstract: 538,742. Electric control systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 15, 1940, No. 10420. Convention date, June 17, 1939. [Class 40 (i)] A control arrangement for an electric motor to move a member e.g. a rolling mill lowering or raising device to a number of positions, comprises a control handle the movement of which determines the movement of the member, operating in conjunction with a series of stops which pre-determine a programme of sequential operations, e.g. successive passes of a billet through the mill for reduction to the required size, the control handle being normally biassed towards a stop by means such as an auxiliary motor. As shown, the control handle 27 may be moved along the bar of a pivoted U-shaped member the arms 32 of which operate, through gearing 39-43 the primary elements 29, 47 of follow-up switches. The handle is moved along the bar step-by-step and may be positioned by notches, and is also moved over a cylindrical surface 36 carrying a series of stops 38 which determines the extent of its angular movement for each of its positions along the bar. Normally the handle is pressed against a stop by an auxiliary motor 45 the circuit of which is opened by a handle switch 93 when it is desired to move the handle along the bar from one position to the next. Movement of the handle causes the coarse control to take charge by operating relay 62 followed by 26 and 15 (or 62<SP>1</SP>, 25, 14 of the new position of the handle requires reverse movement of the operating motor 10), relay 15 or 14 being locked by relay 81 or 81<SP>1</SP> energized by the fine control. Relay 15 completes the circuits of motor 10 and relay 26 is followed in succession after delays to cut out resistances 19-21 to accelerate the motor which through a selsyn transmission 58, 59, moves the secondary elements 52, 55 follow-up switches. When the secondary element 52 of the coarse control is in correspondence with its primary element, relay 62 drops back followed by 26 which causes the re-insertion of the resistances 19-21 into the motor circuit and also the introduction of a decelerating shunt 22 by relay 23. The fine control now takes charge and when its secondary and primary elements are in correspondence, relay 81 falls back to release 15 which de-energizes the motor 10 and allows brake 76 to operate. Specification 408,408, [Group XXXVII], is referred to.

Title: A method of producing aluminium triethyl
IPC: C07F5/06
Filed: 1958-04-02
Abstract: <PICT:0834379/IV (b)/1> Fine activated aluminium powder, hydrogen and ethylene are reacted in the presence of aluminium triethyl under conditions limited by the partial pressure of ethylene as determined by the total pressure of 50 to 300 atmospheres and a reaction temperature of from 50 DEG  to 250 DEG  C.  The aluminium should have no oxide film and is preferably pulverized in a hydrogen atmosphere. The hydrogen, which should be freed from traces of oxygen by treatment with a palladium catalyst, and ethylene may be fed into the reaction vessel separately, but it is preferred to use a mixture of about 2 parts of ethylene to 1 part of hydrogen by volume.  The reaction may be carried out in the apparatus shown; a mixture of aluminium powder and aluminium triethyl (2 : 1) is pulverized by a wet micropulverizer 1 and stored in a tank 2 from which it is pumped to a reaction tower 6.  The solution leaving the tower is led to a liquid-gas separator 7, the separated gas returning via pump 5 to the reaction tower 6, and the liquids being taken to a vessel 8. From this vessel liquids are led to an evaporator 9, the refined aluminium triethyl passing via cooler 11 to a storage vessel 12, and the still bottoms being returned to the tower 6.
