Title: Process and apparatus for filling containers with particulate solid substances
IPC: B65B1/16
Filed: 1965-05-31
Abstract: 1,114,454. Separating particles from gases; centrifugal separators. ST. REGIS PAPER CO. 31 May, 1965 [1 June, 1964], No. 23108/65. Headings BIT and B2P. [Also in Division B8] In a process for filling a container with a particular substance, a mixture of the substance and a gas, inert to the substance, is passed through a filling spout which comprises, inlet and outlet ports, a curvilinear channel between the ports and a gas venting channel connecting with the inner periphery of the curvilinear channel, the mixture being re-distributed, under the action of centrifugal forces produced by the changes of direction to produce a gas stream substantially free from solid particles, which is withdrawn through the gas venting channel, the remaining gas and substance being delivered via the outlet port to the container. The substance e.g. cement is delivered to the inlet port 12 from a fluidising chamber (15), Fig. 1 (not shown) of the closed type having compressed air blown through a perforate false sloping bottom (25) and through a central perforate distributor (33). In one filling spout arrangement the curvilinear channel 14 is in the form of a helical spiral, defined by a strip 38, 39 within a shell 11, and a cylindrical hub 42. A gas venting channel 44 communicates between the channel 14 and a gas discharge pipe 35, which pipe is connected via a ball valve (46), Fig. 9 (not shown) to a vacuum pump. The hub 42 and strip 38, 39 may be formed integrally. In another embodiment, several turns of the spiral channel may be formed separately, Fig. 7 (not shown) with peripheral flanges, and then bolted together. An alternative spout, Fig 12 (not shown), replaces the hub 42 with a rotatable vane. In a further embodiment, Fig. 13 (not shown), the entering fluid stream is separated into a number of parallel streams, by curved concentric vanes in a right angled pipe bend, each stream being thus subjected to centrifugal action. The vanes are hollow and connected to gas draw-off means, operated in their outer peripheries communicating with the gas streams. A gas draw-off channel is also arranged on the inner wall of the bend. On leaving the outlet port the stream is delivered horizontally from a nozzle into the container which is supported by conventional pneumatic clamp means, the gap between the nozzle and the opening or valve of the container being filled by a collar as described in U.S.A. Specification 2,955,796, Fig. I (not shown).

Title: Improvements in or relating to electrolytic cells for the production of aluminium
IPC: C25C3/08
Filed: 1963-06-11
Abstract: <PICT:0976031/C6-C7/1> An apparatus for making aluminium by the three layer process in which a hard refractory metal cathode extends through the top crust, and the intermediate fused electrolyte to the liquid metal layer, and an anode extends into the intermediate zone, is provided with a sacrificial cathode located between the current-carrying cathode and anode and extending only into the top crust, whereby current flowing from the anode through the crust is prevented from reaching the current-carrying cathode. Corrosion of the latter and deposition of sodium products on it are avoided. The latter is also of a "hard metal", i.e. nitrides or carbides of Ti, Ta, Zn, or Nb.  An electrolytic cell comprising a refractory brick wall 12, and a bottom cell lining 16 disposed on an insulating layer 14, has a layer of molten aluminium 22, electrolyte 24, and crust 26. The electrodes are the current-carrying cathode 20 of hard metal, and a carbon anode 28. The sacrificial cathode 30 is disposed between the latter and is also of hard metal, SnO2 or other corrosion-resistant material, and is connected electrically to the cathode.  A number of forms of the sacrificial cathode are illustrated, e.g. as of spike, fork, or spade shape.  In another modification it takes the form of a frame connected directly to the negative bus-bar and extending as a sheet screen between a series of main cathodes and anodes.  The screen is preferably made of a high chromium cast iron.  In a further modification, the relatively small main cathodes are mounted in a cluster centrally in the cell, the anodes on the outer edge, and the sacrificial cathodes of larger cross-section than the main cathodes are disposed between them.

Abstract: 856,125. Photo-electric devices. FOXBORO CO. July 7, 1959 [July 10, 1958], No. 23360/59. Class 40(3). A flow measuring device comprises a vertically disposed tapered opaque tube 24 through which fluid flows between an inlet pipe 14 and an outlet pipe 16 such flow causing an opaque spherical member 25 contained in tube 24 to move up and down the tube in accordance with the flow rate and so vary the amount of light from a source 26 which reaches a photo-electric device 33. The signal output of the latter, which is indicative of the flow rate, is supplied to a recording and control device 12 (which may be located at a position remote from the flow measuring device) from which a signal is derived to control a pneumatically operated valve 13 in the main flow pipe 10. To compensate for light transmission changes due to other causes (e.g. colour changes in the fluid) a further opaque tube of uniform bore is coupled into the flow circuit between the tapered tube and the outlet pipe, one end of the further tube being open to the light source and the other end provided with a photo-electric device the signal produced by which is referenced against the signal from the photo-electric device associated with the tapered tube. The fluid may be a liquid or a gas.

Title: Improvements in separating apparatus, particularly for separating stones from potatoes
IPC: A01D33/04
Filed: 1950-09-23
Abstract: 689,802. Separating solid materials. RICHARDSON, G. D. Dec. 24, 1951 [Sept. 23, 1950; Oct. 19, 1950], Nos. 23384/50 and 25466/50. Class 117 [Also in Group XXX] In an arrangement for separating solid materials and particularly for separating stones from potatoes, a framework 3, which may be mounted on wheels and attached to a potato digger or harvesting machine, carries a series of endless travelling conveyer belts 4, 5, 6, 7, which are horizontal or nearly horizontal, and whose surface is such that stones by reason of their irregular shape and greater weight tend to remain stationary on and be carried along with the belts, whereas potatoes tend to roll along the belts in advance of the stones. The potatoes and stones are delivered by an elevator to the belt 4 which discharges over an inclined shoot 8 on to the belt 5, which travels in the same direction as the belt 6 which is arranged at right-angles to belts 5 and 7. The shoot 11 is provided with inclined ribs of such small height that the potatoes roll over them without substantially changing their direction of motion a side wall 14 retaining them on the belt, but the stones slide down the shoot and are deflected by the ribs towards the middle or opposite side of the belt 6. A similar shoot 15 provided with inclined ribs 13 directs the stones and potatoes on to the discharge belt 7, some of the potatoes rolling over the edge of the belt 7 into a shoot 17 which may discharge into an inclined shcot connected with the bagging shoot 23. The stones remain on the belt 7 and with any remaining potatoes are discharged over an inclined shoot 18, provided with one or more ribs to a rotary disc 20 mounted on an inclined axis. A fixed bar 21 of such shape that the potatoes roll over it into the bagging shoot 23 diverts the stones towards the centre where they slide to the lower part of the disc and may be removed by a scraper. Any potatoes which do not roll over the edge of the disc into the bagging shoot are deflected thereinto by a scraper 24.

Abstract: 1345580 Rotary saws FRIK-SAW MACHINERY Ltd 19 April 1971 [9 March 1970] 23414/71 Heading B5L [Also in Division G3] A control system for a machine tool, such as a rotary saw blade 8 which is moved relative to a workpiece 5 by a pivoted arm 6, comprises means to monitor the power consumed by the saw and means to reverse the advance movement when the power consumed exceeds a predetermined level and to resume the advance movement when the power consumed falls below the predetermined level or another lower level. In the described embodiment a signal representative of the power consumed is provided by a current transformer 15 which senses the current taken by the A.C. electric motor 7 driving the saw blade 8. Advance and reversal of the saw blade is produced by a pneumatic system comprising a main air distributer 32, a spring-loaded valve 21 controlled by an electrically-actuated valve 18, a two-position valve 22 whose state is dependent on which of its ends S1, S2 is supplied with air, and a piston 41 which is connected to the arm 6 and is movable in a cylinder 37 in a direction dependent on the application of air to a needle valve 35 or 40, the unsupplied one of which is connected to exhaust. In a typical working stroke, actuation of a start valve 44 causes air to be applied to end S1 of valve 22 and hence to the valve 40, the piston 41 moving to advance the saw blade 8 at a speed determined by the valves 35, 40. If the motor current exceeds a predetermined value, the output of transformer 15 actuates a relay 17 so causing the valve 18 to be deenergized. This action removes the air supply to end S1 of valve 21, whose spring 31 alters the valve position to cause air to be supplied to the valve 35 and the valve 40 to be connected to exhaust, thus reversing the piston movement. When the motor current falls below the predetermined value, the previously described operation is reversed. At the end of the working stroke, an abutment 47 engages a roller valve 48 whose operation causes air to be applied to the end S2 of the valve 22, so reversing the condition of the valves 35, 40 and the piston movement. Closure of a link 52 short circuits the transformer 15 to allow manual control of the saw.

Abstract: 203,882. Martens, F. A. Aug. 29, 1922. Warp threads, uniting.-In apparatus for glueing together the threads in old and new warps as described in Specification 152,010, a glue-container 6 is used provided with a cover 8 to make the container air-tight except for an opening 7, to which the glue is fed by an arm 10 having a wide free end acting as a scoop and operated by spring-controlled lever mechanism 15, 13, 12, 11, 22. The part 22 is operated by a sleeve &c. 21 on a bar 19 operated by a finger on an arm, which is actuated by a cam disc or " heart " as described in the above-mentioned Specification. A guiding-surface 23 engaging the arm 10, which is immersed in glue, prevents escape of glue from the arm during its upward movement. A guiding- surface 25 engages the arm 13 of the lever mechanism, so that the arm 10 remains stationary momentarily in its upper position whilst a drop of glue flows out through the opening 7 into engagement with the threads 27 to be united by glueing. The threads are subsequently moved on to a catching or gripping wheel 4 and are exposed to an air jet from a spout 28. The wheel 4 is carried by a horizontal shaft 3 provided with a bevel-gear wheel 5, and a pawl wheel 35 driven by a pawl 34 on a lever 32, 33 actuated from the bar 19. Furthermore, the joined threads on the wheel 4 are deposited thereby one pair after another on to a worm 29 driven by bevel gearing 30 and a shaft 31 from the gear wheel 5. Air is blown from the spout 28 through openings in a pipe 36 on to joined threads resting on the worm. The shaft 3 is provided with a heating body for drying the glue-moistened threads.

Abstract: 665,998. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Sept. 8,1948, No. 23621/48. Drawings to Specification. Class 39 (i). The output energy of a linear accelerator is varied by varying the frequency of the applied wave. The apparatus described comprises a wave-guide having internal apertured discs, the apertures in the discs being progressively varied in diameter so that the wave always travels at the same velocity as the particle beam, for example electrons injected at 50 Kv. and emerging at 20 Mv. By varying the frequency of the applied wave from that giving maximum output energy, the output energy can be reduced to say 1 Mv. without impermissible broadening of the effective width of the energy band. The apparatus is useful for generating X-rays of variable hardness for medical purposes. The output end of the guide has a non-reflective termination for absorbing the residual energy, but with the design described most of the wave energy is converted into particle energy. Dimensions and working data are given in an example. Specifications 645,509 and 646,610 are referred to.
