Abstract: 1,192,544. Metal working press. SAMUEL GRIFFITHS (WILLENHALL) Ltd. 3 Aug., 1967 [17 May, 1966], No. 21863/66. Addition to 1,103,599. Heading B3H. [Also in Divisions B5 and F2] A flywheel press having a tool carrying ram (21) (Fig. 1, not shown) reciprocated by a crank, cam, or eccentric on a shaft (22) includes a planetary change-speed gear (25) between the flywheel and the shaft (22), the shaft (22) being braked automatically when the gear (25) is not engaged. The gear (25) comprises an input planet carrier 33 which is belt driven from a motor (28), forms the flywheel, and carries at least three sets of planet pinions 43, 44, 44a meshing respective sun gears 54, 58, 58a, one sun 54 being secured to an output shaft 29 connected to the shaft (22) by gears (14, 15) and the other suns 58, 58a being secured to respective shafts 59, 59a coaxial with the shaft 29. Suns 58, 58a are holdable by respective pneumatically applied disc brakes 16, 16a to form reaction members for different gear ratios, while shaft 29 is holdable by a spring-applied disc brake 11, only one brake being engaged at any time. Pressure air supplied to one or other of brakes 16, 16a also releases the brake 11, a two-way valve (105) (Fig. 5, not shown) being used to select one or other of the brakes 16, 16a. The ratio may be changed during a cycle of operation, e.g. for rapid advance of the tool to the workpiece, slower forming action, and rapid withdrawal, by controlling the two-way valve from a cam switch (109) (Figs. 1, 2, not shown) driven from the shaft (22). Brakes 16, 16a are identical. Pressure air supplied to an annular space 82 of a cylinder 80 urges a piston 81 leftwards (Fig. 4) to act via pins 90 to grip discs 66, splined to a hub 65 secured to the shaft 59, between discs 73 splined to a casing section 68. Springs 88 act on a flange 87 of piston 81 to release the brake when air pressure is removed. Brake 11, comprising a disc 76 splined to a hub 74 which is splined to the shaft 29, between a pair of discs 93 splined to a casing section 190, is applied by pairs of compression springs 102 reacting on a flange 95 of casing 190, and acting on a pressure plate 101.

Title: Material loading apparatus
IPC: E02F9/02
Filed: 1947-08-08
Abstract: 643,732. Load-handling machines. JOY MANUFACTURING CO. Aug. 8, 1947, No. 22060. Convention date, Feb. 16, 1940. [Class 78 (iii)] [Also in Group XXI] A material loading-apparatus of the kind having a vertically and horizontally swinging shovel or the like is characterized in that the shovel is centred or slewed by means which, though operating independently of the vertically swinging means, is controlled by the vertically swinging means in that an element of the latter means controls the application of power to the centring or slewing means. The shovel 13 of a mine car loader is swung vertically on rockers 15 by means of flexible chains 20 wound on flanged drums 21 on a shaft 28. The rockers are compelled to roll in trackways 17 in a frame 4 by means of pairs of guiding cables 18 and 19. Shaft 28 is driven from a fluid motor 24 controlled by a reversing valve 29 operated by a lever 31, Fig. 7. Shaft 28 has a screwed collar 72 keyed to it, Fig. 9, which engages a nut 69 held against rotation by and slidable along a rod 70 secured to a valve casing 59 fixed to the frame member 37, Fig. 7. A cam member 67 is slidable in member 69 and adjustably secured such that after a predetermined amount of rotation of shaft 28 during which the shovel is being raised, the cam surface 66 raises valve stem 64 to admit fluid pressure to two centring cylinders 44 and a cylinder 51, Fig. 4, secured to the base of the frame 4 which is freely pivoted on the frame 1 of a supporting truck for horizontal swinging. The application of fluid pressure to cylinder 44 causes pistons 45 to act through links 47 on pins 49 on the truck frame 1, thus causing frame 4 to be centred, while the piston-rod 53 of cylinder 51, Fig. 5, when fluid is applied, presses down through a slot in frame 4 on to a guide on truck frame 1 until when centred it registers with and thrusts into a recess 54, thus locking the frame 4. In the discharge position the shovel is stopped by shock-absorbing springs 38 having associated with them a cylinder 40 operated on reversal of the motor 24 through a valve 43, Fig. 7, to thrust its piston-rod 41 against a cross-plate 39 secured to rocker arms 14 so as to push the shovel forward to a position where it will fall under gravity, the descent being controlled by again reversing motor 24.

Filed: 1930-07-24
Abstract: 360,357. Centrifugal machines ; ball or tube mills. HARDINGE CO., Inc., 122, East 42nd Street, New York, U.S.A.- (Assignees of Hardinge, H.; York, Pennsylvania, U.S.A.) July 24, 1930, No. 22366. Convention date, Aug. 31, 1929. [Classes 23 and 59.] The joints of a rotary, pulverizing mill of the type described in Specification 263,820, [Class 23, Centrifugal machines &c.], are surrounded by chambers in which the pressure is reduced by means of a pump to below atmosphere and to below that in the mill, to prevent the escape of elastic fluid which is used for conveying the product from the mill. The air or other fluid is circulated continuously through the system by a blower 10 and passes from passage 12 through an annular, conical passage in the mill and returns through a conduit 13 to a classifier 15 and thence by passage 16 to a dust collector 17. The air returns through a conduit 18 to the blower 10. The pressure is controlled by a vent 19 and a butterfly valve 20. The material of undesired coarseness drops to part 21 of the classifier and is returned for further pulverization, as is also the contents of the cone 23. An annular box 28 is arranged around the rotary joint 31 of the mill and air is evacuated therefrom through a conduit 29 leading to conduit 13. The pressure in box 28 is less than that in the mill and atmospheric air enters at the.joint 31. In a modified application to a mill feeding coal to a furnace, Fig. 3, the discharge end of the mill is sealed by a chamber 38 connected by a conduit to the suction side of the blower 33. Sealing-means are also provided at the feed end of the mill. Coal passes from a bin to a hopper 44 and through a valve gate 46 to the mill. Chambers 48, 40 around the joints are connected to the suction pipe 42 or to a venturi restriction in the discharge pipe 37. In another application, the air goes through the mill from end to end. An annular box at the discharge end of the mill is connected to the blower suction. A bucket is connected to a flange on the mill and rotates in the box and carries around particles which leak through the joint to the top of the box from where they drop into the air withdrawn from the box and are returned to the mill. Similar joints may be used in rotary dryers using hot gases.

Abstract: 1,072,171. Filter beds for water. PERMUTIT CO. Ltd. May 23, 1966 [May 26, 1965], No. 22399/65. Heading B1D. In a water filtration plant in which a filter bed 4 is backwashed by filtered water from a tank 2 above and downstream of bed 4, the head of water upstream of bed 4 during filtration builds up in a vertical riser 14 and eventually overflows branch 15 when bed 4 becomes clogged, thereby filling a float tank 16 and opening a valve 13 which connects the upstream side of bed 4 to waste 21. Tank 16 is divided by a weir 17 into chambers 18, 19, chamber 18 having a bleed hole 22 and a float valve 23 opening into chamber 19. Water overflowing from branch 15 into chamber 18 lifts valve 23 to close it, flows over weir 17 into chamber 19 and opens valve 13. Thereafter bed 4 is backwashed by water from tank 2 (arrows), and as the pressure above bed 4 falls flow from branch 15 ceases and chamber 18 begins to empty through hole 22. Finally valve 23 opens, chamber 19 partly drains and valve 13 closes to restore normal filtration flow. In Fig. 1, two filter beds 4, 4' are located in separate compartments of a tank 1, with common tank 2 and false floor 5, so that forward flow water from one bed assists in backwashing the other. Fig. 2 (not shown) illustrates an arrangement whereby each float tank 16 of a multi-bed system has an electric depth probe (28) controlling drain cocks (27) on other float tanks, whereby when one float tank 16 is full and the corresponding bed 4 is being backwashed, the cocks (27) of other float tanks are held open, so that only one bed can be backwashed at once. Tank 2 has an overflow 8 for filtered water. A plurality of beds could be located in separate housings.

Title: Improvements in or relating to sulphur infusers
Inventor: RICHARDS JOHN HARVEY
IPC: B04B15/06
Filed: 1963-06-06
Abstract: Sulphur is introduced into molten metal e.g. copper-containing lead, by passing molten sulphur at a temperature below 160  DEG C. into an enclosure open towards, and closed by, the <PICT:1002495/C6-C7/1> surface of the metal or a matte layer overlying the metal; the enclosure is maintained at such a temperature that sulphur introduced is vaporized and thus readily taken up by the metal. As shown, molten sulphur at 130-140  DEG C. is pumped continuously through lines 7, 7a from a melting pot (not shown).  A needle valve 8 bleeds some sulphur from the lines into a cylinder 9 whose open lower end extends into the matte layer 12-14 overlying molten lead in a vessel 11.  The sulphur reacts with matte-forming metals in the lead to produce mattes of the desired composition.  Further impure lead is charged continuously through the matte layer and pure lead is run off from the bottom of the vessel.  The lower tapering walls of the vessel are chilled to cause accretions of solid lead which trap copper and copper arsenide and from time to time these are melted off. The cppper and copper arsenide then float up to join the matte layer. Specification 1,002,494 is referred to.
