Title: Abrading machines
Inventor: FIELD ANTHONY GERARD
IPC: B24C7/00
Filed: 1968-03-21
Abstract: 1,246,132. Blasting. ABRASIVE DEVELOPMENTS Ltd. 19 June, 1969 [21 March, 1968], No. 13669/68. Heading B3D.  An abrading machine wherein air-borne abrasive is directed at a workpiece includes abrading means provided with air/abrasive input conduits 22 and a suction conduit (21), Fig. 2 (not shown), leading to means for recovering reusable abrasive, an upper hopper 37 for collecting the recovered abrasive, a lower hopper 43 for feeding it to the conduits 22, an intermediate middle hopper 38, and automatic pressure-controlled means for cyclically passing accumulated abrasive from the upper to the middle hopper, and then the middle to the lower. The suction conduit (21) leads to a cyclone 26 via a duct 27, re-usable abrasive being separated by the cyclone to enter the upper hopper 37. A pivotable flap 41 closes an outlet to the middle hopper 38, a similar flap 46 being disposed between the middle and lower hoppers 38, 43, of which the latter is open to atmospheric pressure. On applying operative suction from a fan 34 through a filter 31 and dust extractor 12 the pressure in the upper hopper 37 becomes subatmospheric, and air is drawn from the middle hopper 38 via pipes 75, 64, Fig. 4. When the pressures in the hoppers 37 and 38 have equalized, the flap 41 pivots under the weight of any abrasive above it, which abrasive enters the middle hopper 38, the flap 46 being held closed by atmospheric pressure. As the pressure in the hopper 38 falls, air is exhausted from a space 97 in a diaphragm housing 57 through a pipe 77 at a rate controlled by slots 87 in the seating 86 of a ball valve 82, Fig. 5, the ball valve 82, and a vent 81 being closed by the reduced pressure in the pipe 77. When the pressure in the space 97, and the corresponding pressure in the pipe 64 fall sufficiently, atmospheric pressure in a part 59 of the housing 57 deflects the diaphragm 63 from its seating 70, allowing atmospheric pressure to enter the hopper 38 through the pipe 64, so that the upper flap 41 is closed and the lower flap 46 opened, abrasive from the hopper 38 entering the hopper 43 to reach the conduits 22, Fig. 3 (not shown). Atmospheric pressure in the pipe 64 enters the pipe 77, opening of the vent 81 allowing rapid return of the space 97 to atmospheric pressure so that the diaphragm 63 returns to its seating 70 and the cycle is restarted. In a modification the lower hopper 43 may be maintained at a superatmospheric pressure.

Filed: 1928-05-10
Abstract: 317,345. White, A. E., (Bates Valve Bag Corporation). May 10, 1928. Paper and like bags; securing bags, special means for.-In closing a filled bag, the valve is spread to its greatest extent along one plane and whilst. it is extended it is subjected to the pressure of the contents of the bag to maintain it in the extended position. Thus', the valve which lies in the plane of the empty bag is spread transversely to that plane before it is subjected to the contents of the bag. Normally the spreading is effected by a plug formed of card and coated on both sides with adhesive, but if necessary a metal peelplate may prepare the valve for the reception of the card. A paper valve bag 10 is formed from a rectangular tube and one corner of it is folded inwards to form a valve 12, the mouth of the bag being then sewn over. The bag is filled through the valve and when the filling is complete a. peel plate is thrust into the valve to spread it laterally. The peel plate is replaced by a sealing card 18 and finally the bag is inverted to cause the contents to press the card against the flaps of the valve.

Title: Centrifugal casting process and apparatus for glass and like materials
IPC: C03B19/04
Filed: 1961-04-19
Abstract: A centrifugal casting apparatus comprises a mould support movable in a horizontal plane and a mould mounted upright on the support for axial rotation about a vertical axis, means for rotating the mould and means for concurrently moving the support laterally between two positions whilst the molten material is fed to the mould, termination of lateral movement being calculated to coincide with the discontinuance of feeding and commencement of centrifuging. The process is characterized in that the stream of glass feeding the mould impinges on the mould wall along the line of juncture with the pool of molten glass therein. The stream of glass 12 (Fig. 1) issues from forehearth 11 into mould 42 carried on the shaft of a variable speed rotating motor 41, arranged on a carriage 40 adapted to move over track 46 by fluid operated cylinder 50. Motor 70 rotates cam 65 180 degrees during the feeding cycle. The contour of the cam is such that it controls the rate of travel of the carriage 40 through the medium of valve 55 so as to maintain the stream 12 directed in the predetermined position. At the outset of the feeding cycle the glass stream 12 and mould 42 are in axial alignment, Fig. 3. After a small pool has accumulated in the mould its lateral travel is initiated, the mould rotating at slow speed, the stream being interrupted at the juncture of the pool and the mould wall. This relationship is maintained (through the control exercised by <PICT:0946137/C1/1> <PICT:0946137/C1/2> <PICT:0946137/C1/3> cam 65) until a sufficient quantity of glass has accumulated (Fig. 5).  High speed spinning of the mould is then initiated.  The stream is pinched off after feeding (and before commencement of feeding when the free end of the stream is pinched off) by shear blades 13 and 14 carried in piston shafts of pneumatic cylinders 16 and 17, held in a retracted position by springs 18 and 19, arranged in the same horizontal plane and butted against one another at the stream axis.  The blades are operated to pinch off the stream at the appropriate time in the feeding cycle.  A shoot 30 can be projected by air cylinder 31 into the path of the stream 12 to divert the stream.  An electric circuit for controlling the apparatus is disclosed.

[Class 51 (i).] In a steam-generator furnace of the kind in which the ashpit is divided by an horizontal partition H into an upper compartment C through which primary air is supplied to the grate a<2> and a lower passage D traversed by secondary air on its way to the flue beyond the bridge a<3>, the secondary air is heated before delivery to the gases in a refractory arch B disposed behind the bridge a<3> and formed with circumferential passages' b<4>, Fig. 5, with which the radial delivery ports b<5> communicate. In the construction shown in Fig. 1, the supplies of primary and secondary air to the compartments C, D are controlled by a single sliding damper K interconnected with the fire-door T in such a manner that, when the door is opened for firing, the damper is moved to a position in which the primary air inlet is substantially closed while the secondary air inlet is fully open. A three-armed lever, pivoted at r<4>, has one arm R<2> connected to the damper, a second arm R<3> carrying a counterweight r<5>, and a third arm R<1> projecting into the path of a stop F<1> on a shaft J. The latter is so arranged that it is moved longitudinally by the opening and closing of the door T, and is secured at its outer end to the piston of a dashpot E<1> which regulates the speed at which the damper K returns to normal position after the door T is closed. Fig. 10 shows a modification in which the two air supplies are controlled in constant proportions by dampers C<1>, D<1> adapted for automatic operation by a pyrometer or pressure gauge P arranged within the furnace, or alternatively by the opening and closing of the firedoor T. The movable member p<1> of the device P is arranged to contact, on any deviation from the normal temperature or pressure, with one or other of a pair of contacts to start up an electric motor M which rotates in a direction to open or close the dampers C<1>, D<1> as the case may be. The connections between the motor M and the dampers comprise worm gearing m<2>, m<3>, shaft G, rods f<1>, adjustable lost-motion devices F, and dashpots E. The shaft G is connected by a clutch t<2> to the spindle t<1> of the fire-door T, the clutch being operable to cut out the control by the motor M and connect the shaft G directly to the spindle t<1>. A device is provided to enable, when fire-door control is being employed, the shaft G to be disconnected from the worm wheel< >m<3>. The normal positions of the dampers C<1>, D<1> are determined by the angular adjustment of a member d<4>, Fig. 13, which is fitted with compression springs d2, d<3>, connected to the damper rod d<1>.

Filed: 1917-10-04
Abstract: 119,678. Shaw, G. A. Oct. 4, 1917. I'),ojccti[C,3 projectile fuses.-Consists in a hand grenade in which the casing has a separate compartment for the explosive charge and detonator, and also has loosely arranged within it a number of projectiles, which by their movement when impact occurs effect the detonation of the explosive. In the construction shown, the grenade has a dish-shaped casing formed of sheetmetal members joined together at their edges. The inner compartment is formed by a tube 3 for receiving the detonator-holder, and a charge-container 4 connected thereto. The space between the inner compartment and the outer casing is filled with convex disk-shaped projectiles 20, having sharp edges. The tube 3, shown separately in Fig. 4, has holes 11 through which can pass firing-pins 10 mounted on flexible plates 9 secured at their ends to the tube. The detonatorholder 12, Fig. 5, is a tube with holes 13 corresponding to the holes 11, and when inserted in the tube 3, can be turned so that the holes 13 are either in or out of register with the holes 11, the tube 12 being held either in the safe or the opera-. tive position, as required, by the engagement of a hook 15 with notches 8, 7 in the head 5 of the tube 3. Before throwing, the tube 12 is set to the firing position, and, when impact occurs, the crowding of the projectiles 20 against the plates 9 forces the pins 10 through the holes 11, 13, thus causing the detonator to explode.
