Title: Improvements in and relating to the control of electrically driven soot blowers
IPC: F28G15/00
Filed: 1944-06-22
Abstract: 580,605. Control of several motors. BRITISH THOMSON-HOUSTON CO., Ltd., and JEFFERSON, H. F. June 22, 1944, No. 11887. [Class 38 (iii)] An electrically operated soot blower system, of the type wherein the heads are operated automatically in sequence, comprises an automatic multi-way switch which disengages from normal operating sequence those heads requiring infrequent operation, and causes them to be operated after a pre-determined number of operations of the other heads. The invention is described as applied to the electrically operated soot blower disclosed in Specification 526,405. A multi-contact switch PT is arranged so that, in the position shown, the whole sequence will be effected, since the break at X in a connection 11; through which is passed the impulse from the fourth head to start the fifth, is bridged by the contacts b of the switch PT. At the next cycle of operation, a press button SPB is actuated to start the first head and shift the moving contacts of the switch PT of the next set of fixed contacts, breaking the connection 11 to stop the operation at the fourth head, the system then being re-set for another cycle. On each subsequent cycle of operation, the moving contacts of the switch PT are stepped on, until the fixed contacts of row a, which are connected to a contact d, are reached, and the coil of the switch PT is energized to open the contacts d, which are then automatically closed and opened to step on the moving contacts until the position shown is again attained. A single circuit push button and a relay may replace the double-contact push button shown.
Patent GB-801743-A (GB)
Title: Extraction of plutonium and uranium
IPC: G21C19/46
Filed: 1955-04-25
Abstract: Plutonium or uranium or both are extracted from an aqueous nitric acid solution containing fission products by treating the solution, in which the plutonium is in the tetravalent or higher state and the uranium is in the hexavalent state, with tributyl phosphate which forms a water-immiscible phase containing the plutonium or uranium. For extraction of both uranium and plutonium, the aqueous nitric acid solution treated should be at least normal in nitric acid, preferably 2-7 N.  The tributyl phosphate may be diluted with an inert liquid, e.g. kerosene or benzene.  Uranium and plutonium present in the water-immiscible phase may be separated (a) by contacting the solvent phase with an aqueous N-SN nitric acid solution containing a reducing agent, e.g. ferrous sulphamate, hydroxylamine, or hydrazine in a concentration of 0.05 N, when the plutonium is reduced to the trivalent state and transfers to the aqueous phase, leaving the uranium in the solvent phase; or (b) by contacting the solvent phase repeatedly with 0.1-0.3 N nitric acid, when the plutonium passes preferentially into the aqueous phase.  Plutonium or uranium may be removed from the solvent phases by washing with water.  In an alternative process, the initial solution is made 0.1-0.3 normal in nitric acid and extracted with tributyl phosphate; only the uranium is extracted, the plutonium remaining in the aqueous phase, from which it may be obtained by increasing the acidity to 2-7 N and contacting with tributyl phosphate.

Title: Improvements in pressure-reducing devices for supplying fuel gas to internal combustion engines
IPC: F23D14/60
Filed: 1939-04-21
Abstract: 527,815. Regulating. FAIRWEATHER, W. C. (Majert, R., Majert, M., and Petry, J.). April 21, 1939, No. 11992. [Class 7 (vi)] [Also in Group XXIX] In a pressure-reducing device for supplying gaseous fuel to internal-combustion engines, a richer mixture is obtained at higher outputs by increasing the diaphragm loading of the device. Fig. 1 shows a pressure-reducing device comprising a diaphragm 9 operating through a bell crank 7, 8 a valve 5 admitting pressure gas at 2 beneath the diaphragm. The suction of the engine connected at 3 tends to open the valve 5 against the pressure of a spring 10, and the richer mixture is obtained by bringing into action a spring 13 above the diaphragm. This spring acts between the diaphragm and a plate 15 connected thereto by a chain 16, the plate 15 being normally free to move with the diaphragm. When the throttle valve is opened to a pre-determined extent, a lever 20 is brought to bear on the plate 15 through an adjustment screw 17, so as to bring the load of the spring 13 to bear on the diaphragm in the opening direction of the valve 5. In a modification, a leaf spring is brought to bear on the diaphragm by an electromagnet which is energized by a switch connected to the accelerator pedal. Hydraulic or pneumatic connection with the accelerator may also be used.

Title: Improvements in or relating to casting machines
IPC: B22D13/00
Filed: 1947-05-08
Abstract: 646,782. Centrifugal casting - machines. RUBISSOW, G. A. May 8, 1947, No. 12501. Convention date, May 9, 1946. [Class 83 (i)] Moulds.-A centrifugal casting-machine comprising a central pouring gate supplying a laterally arranged mould is driven by a single driving shaft through one or other of two clutches, one of which serves to rotate the gate and the mould about a vertical axis and the other of which serves, in addition, to rotate the mould about a horizontal axis, the engagement and disengagement of the clutches being under the control of an oil-operated piston. To the base portion of the machine frame 10 is bolted a standard 11 about which a unit comprising parts 45, 46, 48 and 49 rotates on bearings 15 and 16 when driven by a shaft 51 and gears 52, 50. The part 45 houses the refractory wall 39 of a ladle arranged on the axis of the standard and beneath a pouring funnel 35 bolted to an upper portion of the frame. Extending radially from the lower end of the ladle is a gate 42, around which, rotatably mounted in bearings 62 is a mould support comprising a body 70 with an integral gear 96 and a member 71 provided with arms 72, 73 which fit into bayonet slots 75 in the periphery of a mould 76. Gear 96 meshes with a gear 95 formed on an annular clutch member 91 rotatably mounted between the standard 11 and a surrounding part 49 of the first-mentioned rotating unit. Extending radially inwards from the member 91 are two vertically spaced sets of clutch plates, those of the upper set 97 alternating with plates 99 extending outwardly from the cap part 46 of the rotating structure and the lower set 98 with plates 100 extending outwardly from the standard 11. Operating within a bore of the standard is a piston 21 with a rod 30 carrying a cross arm which can act through an annular member 102 to engage either the clutch plates 97, 99 or the plates 98, 100 under the control of the piston which is operated by oil under pressure. Whether the oil is being supplied to above or below the piston, some of it passes through passages in the piston to a central bore in the rod and thence to the bearings and clutch. With plates 97, 99 in engagement, the mould support and the ladle and associated casing rotate as a unit about the axis of the standard, but with plates 98, 100 in engagement, the gear 95 is held fixed and as the gear 96 is moved around the axis of the standard, it rotates the mould support about the axis of the gate 42. The machine may carry two, three or four mould supports uniformly spaced. The mould comprises a casing 77 and base 79 and is prepared interiorly with patterns and sand in the known manner. When the mould is mounted by means of the bayonet joints, it is pushed into position against the action of springs 83 which act on a cover member surrounding the gate 42 which projects therethrough.

Abstract: 542,940. Catculating-apparatus. WILLENS, R. A. A. Aug. 2, 1940, No. 12506. [Class 106 (i)] An apparatus for facilitating the selection of at least three values each from a range of a finite number of distinct values to provide a given function of the values selected which shall approximate most closely to a desired value lying in a finite and continuous range, comprises two scales marked in accordance with every possible value of two sub-functions of the variables to be selected and means for moving the scales independently and together to bring the desired values into juxtaposition according to the given ratio. In one form of apparatus, as described for facilitating the selection of a set of at least two pairs of gears from a range of gears, to give a compound gear ratio approximating to a desired ratio, the scale members are constituted by film strips 3, 4, Fig. 1, carried by reels 5, 6 and 7, 8 and sprocket wheels 13, 14 and 15, 16 on a conventional type of film viewer 1 provided with a screen 9 and hinged masking flaps 10, 11. The shafts 19 ... 22 of the sprocket wheels are adapted to be driven in either direction by pairs of bevel gears 23, 24 and 23, 26, Fig. 2, working independently or in geared relationship. The bevel gears 24, 26 are mounted on shafts 25, 27 with gears 28, 29 engaging a gear 30 driven by a hand crank 31. The gear 29 is free on the shaft 27 but may be secured thereto by means of a clutch 32 operated by a hand wheel 33. A hand wheel 34 is provided by means of which the shaft 27 may be driven independently. Spring belts 35 drive the reels through friction clutches. The scales shown in Figs. 4 and 5 are designed to facilitate the selection of four gears from a range of seventy-one gears having every possible number of teeth from twenty to ninety. Each film carries two scales 42, 43 ; the scale 42 is a simple logarithmic scale and the scale 43 is formed of transparent wedgeshaped marks on a black ground a mark being provided for every possible product of any two gears in the range. The mark that represents the product of two gears of twenty teeth is opposite the unit mark of the scale 42. The marks are identified by numbers and tables of the numbers and products are used to determine the products. In operation the unity mark on one scale 42 is adjusted opposite the desired transmission ratio on the other scale and then the scales are coupled to move together until two of the transparent marks, one on each film, coincide. The numbers are noted and the tables give the products. The sensitivity of the device may be adjusted by laterally moving one of the film strips by the action of wing nuts 50 against springs on the spindles. In a modification, Fig. 6 (not shown), the scales are marked in a helical manner on nested cylinders. The upper half of each cylinder carries a scale corresponding to the scales 43. A logarithmic scale corresponding to the scale 42 is marked on the lower half of the inner cylinder and co-operates with an index finger at the lower end of the outer cylinder.

Abstract: 399,249. Switches held set and freed mechanically. AVERY, Ltd., W. & T. and LEESON, A., Soho Foundry, Birmingham. May 3, 1932, No. 12692. [Class 38 (v).] An electric switch for controlling the closure of the feed gate of a weighing machine comprises a tiltable mercury tube 12 co-operating with a tumbler 18 which in turn co-operates with the weighbeam 22 and with a locking means 19. As shown in a weigher having a sliding feed gate 4 opened by a hand-lever 7 and retained in the open position by a trigger 7b, the completion of the charge causes the weighbeam 22 to rise and displace the tumbler lever 18 thereby permitting the mercury tube 12 to'fall by gravity into the position shown in Fig. 3, the tumbler lever being temporarily retained by a spring-pressed locking lever 19. The fall of the mercury tube closes the circuit of a solenoid 11 which then knocks up the trigger 7b and allows the feed gate to close under the action of springs 16. As the gate closes, a bent arm 15a carried thereby restores the mercury tube to horizontal position thus opening the solenoid circuit. On removal of the filled bag from an outlet 6 the weighbeam 22 displaces the locking lever 19 and the tumbler lever returns to its initial position beneath the mercury tube. The end of the weighbeam is in the form of an adjustable inclined plate 21 to permit of accurate setting relative to the tumbler lever, and affords a means for compensating for the material in. suspension at cut-off.
