IPC: C01G1/06
Filed: 1922-08-30
Abstract: 190,688. Jacobson, B. H. May 31, 1922, [Convention date]. Addition to 181,885. Aluminium, antimony, arsenic, iron, tin, zinc, and other chlorides; double chlorides.-In the production of anhydrous chlorides by the reaction of chlorine on a metal in the presence of bromine, as described in the parent Specification, a salt such as sodium or potassium chloride or bromide is added so as to maintain the product liquid without necessitating a high temperature or pressure. When a bromide is used it is not necessary to add free bromine. The invention is described with reference to aluminium chloride. In an example, aluminium chloride and sodium chloride are melted in a covered iron pot or rotating ball mill, and aluminium and bromine are then added, the temperature being suitably 125-150 C. From time to time portions of the melt are drawn off, and more aluminium and salt are added and, when necessary, some additional bromine. The product withdrawn may contain 5 to 30 per cent of sodium chloride, but is suitable for use in the Friedel-Crafts reaction. If the temperature is maintained at 200 C., aluminium chloride alone is volatilized and is recovered in a condenser.

Title: Improvements in and relating to superheaters and the like
IPC: F22G1/16
Filed: 1925-09-22
Abstract: 240,192. Akt.-Ges. Brown, Boveri, et Cie. Sept. 22, 1924, [Convention date]. Combustion products, returning to furnaces.- In superheaters, feed-water heaters, tubular boilers, &c. which have the temperature reduced by returning smoke gases to the furnace, these gases are introduced at the point of lowest pressure in a restricted nozzle through which the furnace gases pass prior to use. As shown applied to a superheater the tubes D are shielded from the direct flame of the furnace A with the travelling grate B by a nozzle-shaped part C built of refractory bricks. Waste gases taken off at H are conveyed by a fan J through a pipe K and forced at a high velocity through jet nozzles L at the throat of the nozzle-shaped part C so that a suction is caused acting on the furnace gases. Soot or dust may be removed through the door M. The superheater tubes D comprise nests of coils in which the steam travels in counterflow to the waste gases, but at high superheat temperatures the steam may travel partly in the same direction as the gases so that the tubes conveying the hottest steam are in the region of the cooler gases. Air is fed to the grate B through an air heater F and a pipe G. The central return pipe K forces the gases to sweep over the tubes D in a uniform manner but when the superheater tubes are differently arranged the return pipe for the gases may be situated outside the setting. To protect the nozzle-shaped part C from the flame, the waste gases may issue through an annular nozzle arranged below it, through the centre of which the furnace gases are drawn. Additional blowers may be provided, and the invention is stated to be applicable also to coal-dust, oil or gas furnaces.

Title: Improvements in or relating to sequence control switching devices for conveyors
IPC: B65G23/00
Filed: 1948-09-09
Abstract: 648,503. Endless belt conveyers. CLARKE, CHAPMAN & CO., Ltd., and SHORTT, J. S. Sept. 9, 1948, Nos. 23771/48 and 23288/49. [Class 78 (i)] [Also in Group XXXVII] A sequence control for causing the stopping and starting of a main belt conveyer to control a subsidiary conveyer is characterized in that a linearly moving member operated by a centrifugal governor rotated by the main belt is arranged to operate micro-switches by contacts carried by a hinged plate, the switches being in circuit with the motor of the subsidiary conveyer. The main belt f, Fig. 1, rotates a pulley g<1> which may be fixed or coupled by a free wheel device to a shaft e mounted in the casing a. Casing a is pivotally mounted at b<2> on a pair of brackets d<1> such that it is out of balance, pressing pulley g<1> against the belt f. Shaft e is hollow within the casing and the linearly moving member j slides inside. Brackets h2 on the shaft pivotally support governor weights h which have extensions h<3> extending through a slot e<4> in the shaft to engage the member j. In a chamber c a pair of brackets n pivotally support at n<1> a plate m carrying the contacts m<2>, m<3> and the brackets are joined by a pin n<2> in which is slidably mounted one end of a rod s. The other end of rod s is screwed into a pin m' mounted in brackets on the plate m. On the reverse side of plate m a mounting supports a bearing m<1>. By means of a spring s<1> between pins n2 and m' bearing ml is pressed on a rounded portion j<1> on the end of member j which in turn presses on the extensions h<3> to keep the weights h retracted. At speed weights h fly out against a flange k pushing plate m so that the contacts m<2>, m<3>, Fig. 4, engage operating levers o<1>, p<1> of the micro-switches o, p, which are pivotally mounted on brackets r and adjusted by means of a screw r<1>. Adjustment of screws r<1> and s allows different sequential timing of the operation of switches o, p. On the main conveyer being started contacts o<2>, Fig. 5, of switch o close first, supplying a starting current through the circuit u, and after a time interval contacts p<2> of switch p open, introducing resistance t into the circuit. A separate manual control switch v is also included in order to operate the subsidiary conveyer independently of the main conveyer. The circuit through switch v can only be closed when the main conveyer is stopped, by providing a contact o<3> on switch o which is disconnected when contacts o<2> close.

Patent GB-406678-A (GB)
Title: An improved method of and apparatus for electrically operating or controlling road traffic signals
IPC: G08G1/08
Filed: 1932-08-25
Abstract: 406,678. Road signals for controlling traffic. SCOTT, W. H., Gothic Works, and WOODS, R. G., 147 Newmarket Street, both in Norwich. Aug. 25, 1932, No. 23814. [Class 118 (ii).] The speed of rotation of a continuously rotating drum, which controls the signal lamps, is speeded up by traffic waiting on a blocked road, the speeding up being cut out by vehicles passing on the open road. Speeding up is effected either by increasing the stroke of the stepping pawl or by increasing the rate of impulsing to the stepping magnet or, as shown in Fig. 3, by both these methods simultaneously. The lamps are controlled by the drum 1 which is stepped by magnet 2 co-operating with pawl 5. The stroke of the pawl can be lengthened by energizing magnet 17 which swings the arm 19 to vary the effect of the adjustable ratio cams 4 on pawl 5. The operation of these cams is described in Specifications 385,618 and 387,030. The rate of impulsing is altered by cutting resistance 34 in or out of the impulsing circuit. With the drum and other apparatus in the position shewn, the green lamps are shewing along the main road containing pad 7 and the red lamps are shewing on the cross road containing pad 7<1>. The drum is driven at a slow rate, the circuit for impulsing being M1, 3c, 3b, 35, 3d, 12, M2 and then M1, 2, 3a, 35, 3b, 3c, 12, M2. Should a vehicle arrive on the cross road, pad 7<1> is operated completing a circuit M1, 71, c, e, 29, 24, M2 for operating the recording relay 20. Relay 20 locks over its contacts 23 and completes, over contacts 37, a short circuit for the resistance tapped at 35 and over contacts 22, an energizing circuit for magnet 17. Magnet 17 rocks arm 19 to increase the stroke of pawl 5 and closes contacts 40 and 21 which complete a parallel short across 35 and the circuit of winding 11 of relay 9 respectively. Relay 9 can energize only if windings 10 and 11 are both energized and when energized this relay releases slowly, the rate of release being controlled by windings 11 and 12. If no vehicles pass along the main road, the drum is quickly stepped through the amber period and gives right of way to the cross road. If however traffic is passing along the main road, each vehicle depresses pad 7 which is now effective to energize relay 9 (over b, a, 26). Relay 17 releases and the short across 35 is broken so that the speeding up is cut out. Relay 9 remains energized for its predetermined slow period and then recloses its contacts to recomplete the speeding-up circuits. The resistance 33 is cut into the impulsing circuit whilst the amber lamps are showing to ensure a constant amber period and during this period the relay 9 is cut out by the gaps in the segments b, c of the contact drum. The relay 20 is, however, changed over to be controlled by the pad in the blocked road just before the amber period commences so that vehicles may register their presence during the amber time.

IPC: G21C7/22
Filed: 1967-05-23
Abstract: 1,145,617. Controlling reactors. ATOMIC ENERGY OF CANADA Ltd. 23 May, 1967 [8 July, 1966], No. 23847/67. Heading G6C. In a nuclear reactor control system, a neutron absorbing liquid is displaceable in a U-tube, 17, within the core. The absorber 11 is contained in a reservoir 10, external to, and above, the core and is supported there by helium gas pressure in the U-tube and the tube 22. Rapid reactor shut-down is effected by gravitational movement of 11 downwards into the core, upon the opening of valve 24. Criticality is resumed by the slow pumping of the fluid 11 upwards into 10 through the small bore tube 18, the valve 24 being closed. Gas pressure from pipe 26 communicates, through tube 27, with port 14 and the liquid surface 15 to maintain the liquid within 10. Expulsion of liquid 11 during boiling is prevented by float valves 13, 23.

Abstract: 691,323. Reinforced concrete. NILSSON, A. B. Sept. 29, 1950, No. 23855/50. Class. 20(iv) [Also in Group V] Concrete is cast into a tubular mould 4 and vibrated by a vibrator 21. The moulded concrete member is then removed from the bottom of the mould, passed through a steam curing chamber and carried off on a wagon. The casting may be done in one or more stages or continuously. Reinforcing wires 14 on a drum 6 are incorporated in the members by passing them through distribution plates 11, 8, 10. The lower ends of the wires have weights 19 to keep thewires straight and to cause the wires to move downwardly through the mould. Weights may be removed as the member is cast, to compensate for the weight of themember, and the weights may be dispensed with when one member has been formed. Movement of the wires is prevented during casting by a brake on the drum 6. End plates 12 are stored above the mould and released one at a time to form a bottom for the mould, and for the moulded member. The mould is preferably of such a length that the steam curing does not take place until the concrete has partly hardened. In .a modified construction, Fig. 4, a core 26 is. provided for forming pipes. The concrete is vibrated by a vibrator 27 fixed to the mould. Adjacent members may be interconnected by chains, Fig. 7 (not shown), which are attached to bands on the member. The bands may have rollers which engage cam rails to bring the members from a vertical to a horizontal position on delivery.
