Title: Apparatus for the controlled delivery of liquids
IPC: G03D3/06
Filed: 1965-04-09
Abstract: 1,089,035. Regulating fluid-flow. AGFA A.G. April 9, 1965 [April 9, 1964], No. 15224/65. Heading G3H. When a storage tank 1 and connected intermediate chamber 4 are filled with liquid and the filling cap 3 is fitted, a vent pipe 6 from the chamber 4 is filled with liquid to the same height as that in the tank 1. Each time an electromagnetic valve 10 is opened by an impulse device controlled by material introduced into a treatment tank 9, a quantity of liquid flows into the latter from the chamber 4 via an exchangable restriction 12. Until the pipe 6 is empty the quantity of liquid delivered is greater than normal, the liquid head then remains substantially constant. When the liquid in chamber 4 uncovers a pipe 5 air flows from the chamber into the tank and an equal volume of liquid enters the chamber from the tank. The restriction and valve may be replaced by a small-bore tube, and a number of plastic tanks and chambers may be welded together to form a multiple unit. The tanks may be opaque and include sight-glasses.

Title: Improvements in or relating to the treatment of steel
IPC: C21C5/36
Filed: 1957-05-14
Abstract: The basicity and fluidity of a steel making slag is controlled by the addition of a basic product containing at least 60 per cent by weight of free and combined lime and at least 10 per cent of silica, at least one-third of the lime being in the form of calcium silicate, the remainder being alumina or other alkali or alkali earth bases or a mixture of such bases.  A cement clinker of said composition is ground to dust and added to the bath in bulk or injected by means of a gas such as air and/or oxygen, or carbon dioxide.  The product may be used to form the second slag in the double slag process for dephosphorizing Bessemer steel, or during the refining phase in the open hearth furnace.  When added to a ladle it is preferable to heat the product to 950 DEG -1050 DEG C. and also it may be mixed intimately with a recarbonizing agent before its addition to the bath.

Title: Improvements in and relating to injection moulding machines
IPC: B29C45/50

Abstract: 760,480. Injection-moulding machines. BAIGENT, K. H. June 4, 1954 [June 5, 1953], No. 15573/53. Class 87(2). Two or more longitudinally-slidable rotating screws 10 urge heated plastic material forwardly from the injection cylinder 13 through the nozzle 16 into a mould 78. The resulting back pressure pushes the screws rearwardly. Then the screws stop rotating and are pushed forward to act as pistons to fill the mould. The screws are rotated by a hydraulic motor 52a and are reciprocated by a hydraulic piston 11. The screws, motor and piston are interconnected and slide as a whole in a way 34 on a base 15. The connection between the motor 52a and the screws includes a shaft 51 carrying a worm 50 that drives a worm gear 49 having on its interior gear teeth 48 that mesh with pinions 47 keyed to the worm shafts 30. The worms rotate in the same direction. Fig. 9 shows the screwsmotor-piston assembly in its forward position. A hydraulic pump 81 feeds motor 52a through line 88 or piston 11 through line 75, the fluid supply being switched by valve 86. In the (idle) Fig. 9 position a time switch has moved valve 86 to a neutral position in which the hydraulic fluid is circulated in a closed circuit comprising line 85, valve 86, line 87, reservoir 83 and line 84. Operation :-(1) A mould being in position to close the nozzle, a time switch energizes a solenoid to move valve 86 to direct fluid to motor 52a whereupon the screws rotate and the assembly slides back (2) A stop 79 on the motor operates limit switch 80 which energises a solenoid to shift valve 86 to transfer the fluid supply from the motor to piston 11. (3) The assembly is pushed forward to exert pressure on the material in the mould, and remains there for a period determined by the time switch. (4) The time switch moves the valve 86 back to the neutral position.

Purifying saccharine liquids.-Liquids of progressively decreasing purity all derived from liquid of the same character are passed successively through a filter containing a certain amount of finely-divided decolorizing carbon; the carbon is finally mixed with the most impure liquid and then separated from it. The Figure shows suitable apparatus diagrammatically. The carbon may be supplied initially to a filter G or mixed with the purest liquid in a tank E. In the latter case, the carbon is separated in the filter, the pure liquid passing away through a pipe e<2>. Liquid from 1) is then passed through the filter to tank E and so on successively. After liquid from tank B has passed to tank C, the carbon is discharged to tank A and mixed with liquid therein, separation afterwards taking place in filter G through which the liquid passes to tank B. Each liquid instead of being passed once through the carbon in filter G may be circulated through it. The tank E is preferably provided with agitating means and with steam coils for heating. The liquid may receive preliminary treatment in a decanting-apparatus or a centrifugal separator F<3> or with a purifying agent in a tank F. Kieselguhr, fuller's earth, charcoal, lime, carbonate and phosphate of lime, sodium phosphate and calcium sulphate are mentioned as suitable purifying agents for this preliminary treatment. A preliminary filter f may also be used.

[Class 135] A water-cooled valve for controlling the flow of hot gases, in for example a furnace, comprises an open-ended tank 1, Fig. 1, one face of which cooperates with a valve seating around the passage 4, of a sufficient water capacity to keep the metal cool by boiling for a considerable time in the event of the supply of cooling water failing. An apron 6 is arranged round the top of the tank and dips into an annular water trough 5 to provide a seal around the top of the casing whilst allowing free movement for the valve to bear firmly on to its seat.

Abstract: 695,250. Barrel locks. VILLALBA, P. DEL. P. July 5, 1951 [July 19, 1950], No. 16005/51. Class 44 A lock comprises a stationary casing having a rotatable barrel carrying a toothed wheel or equivalent in mesh with a rack on the bolt, and a series of variably settable locking elements capable of being released by means of a key having within its shank variably settable wards, projected from the shank after the key has been inserted, and engaging and displacing the locking elements. As shown in Fig. 1, a barrel 29, with a rear extension 27, is rotatably mounted in a casing. The key, Fig. 15, which is of flat box-like form, is inserted through a rectangular opening 1a, Fig. 1, in the barrel 29, and contains a number of toothed racks 43, Fig. 15, secured in predetermined positions to a sliding plate 50, which, after the key has been inserted, is projected from the shank of the key by operating a sliding band 33. The plate 50 and associated racks pass into a keyway 2, Fig. 1, and the racks engage toothed segments S pivoted tumblers 11, lifting the heads 11 a of the tumblers out of slots 26a formed in the bolt 26 of the lock. The bolt 26 can then be moved by rotation of the barrel through a pinion 16, Fig. 7, meshing with a rack on the bolt. The pinion 16 has slots through which the heads of the tumblers 11 project. A number of weights 7, Fig. 1, sliding on fixed rods 8, bear on noses 12 of the segments S. A brake 9 adapted to hold down the weights 7 is connected to a pair of sliding rods 10 which have at their rear ends a finger piece 25. Sliding in the extension 27 of the barrel is yoke 22, the forward end of which is adapted to engage the upper parts of the tumblers 11 when the yoke is pushed in against the action of a spring 14. By this means the bolt can be operated from inside by pushing in the yoke 22 so that its end 13 lifts the tumblers, and then rotating the yoke. The tumblers can be held raised and inoperative by pulling out the finger piece 25, so that the weights 7 are held down, and holding it out by a wedge. The key,'Fig. 15, is in the form of a shallow box, the front wall having holes 34 into which project pins 5, Fig. 2, on the plate 3 in the barrel when the key is inserted, displacing spring- pressed plungers, 42, Fig. 16, housed in a compartment at the front end of the key. Displacement of the plungers 42 brings into alignment transverse grooves in the under sides thereof, and a rod 37, which normally blocks the opening in the front of the key, can then be lifted into the aligned grooves by the chamfered front ends of the key racks 43 on operation of the sliding band 33, Fig. 15. The racks are held on the plate 50 by means of a member having a transversely serrated lower surface engaging the teeth of the racks and secured to the plate 50 by a spring pin; the racks can thus be set to suit the lock tumbler setting.
