IPC: B03B4/00
Filed: 1928-06-06
Abstract: 322,480. Birtley Iron Co., Ltd., Bramwell, I. L., and Holmes, C. W. H. June 6, 1928. Drawings to Specification. Pneumatic separating; pneumatic separators combined with sifting-apparatus.-A process for the separation of intermixed materials of different density and of mixed sizes, such as coal and shale, consists in first treating the mixture on a pneumatic separator and removing the large particles of the denser component, e.g. shale, in a substantially pure condition and then passing the bulk of the materials through a screen which removes the larger sized particles consisting principally of the lighter component e.g. coal in a substantially pure condition. The materials passing through the screen consist of a mixture of the same character as the original charge but comprising smaller particles and is then subjected to a repetition of the treatmet. Alternatively, a, middlings product may be taken from one or more of the pneumatic separators and returned to the beginning of the process and the material passing through the screen at any stage may be also returned for re-treatment.

Abstract: 240,566. Bevan, C. July 10, 1924. Moving-chamber apparatus.-The apparatus is adapted to traverse and to present the containers to measuring and filling means in contiguity with which the containers are raised to close the bottom of the measuring vessel and gradually lowered therefrom to effect the filling of the containers. In the reservoir 10 for the material rotate arms 11 sweeping the material towards a hole or holes 12 in the bottom below which rotates a disc 13 from which depend measuring vessels 14 open at each end. A rotating disc 15 forming with the disc 13 a turret carries vertically sliding holders 16 adapted to receive the canisters 17 to be filled. The rods 18 of the holders 16 rest on a fixed cam track having an ascending portion 20, a level portion 21 below the openings 12 and a descending portion 23 which is stepped to shape the material in the filled canisters. In a modification the disc 13 is dispensed with, the measuring vessels 14 being fixed to the bottom of the reservoir 10 which rotates, and fixed arms are provided within the reservoir to sweep material into the chambers 14 and to wipe excess from the tops of the vessels. The measuring vessel may be telescopic or may be fitted with detachable linings to vary the capacity. The material is supplied to the reservoir through a flexible pipe entering the top and extending nearly to the bottom of the reservoir. The bottom of the pipe is provided with a hinged flap which automatically closes when a predetermined amount of material has entered the reservoir. The cover of the machine may be connected to a fan to protect the operatives from dust. The port or ports through which the material is delivered to the measuring vessel may have a tubular guard adapted to be opened by the raising of the canister, the guard remaining closed if the canister is present. The canisters are conveyed to the machine by a conveyer 29 being fed on to a disc 31 geared to feed the canisters on to the carriers 16. Associated with the feed and with the delivery of filled canisters is a pivoted deflector 32 controlled by the cam 33 which simultaneously moves an empty canister from the disc 31 on to the turret and removes or aids in removing a filled container to the belt 30, the latter having a curved deflector 34 below which the deflector 32 moves.

Title: Improvements in branch connections to conduits containing two fluids which do not mix
IPC: F16L37/26
Filed: 1963-04-29
Abstract: 973,335. Pipe connections. AKTIEBOLAGET MANUS. April 29, 1963 [April 30, 1962], No. 16777/63. Heading F2G. [Also in Division A1] A device for connecting to a main conduit 1 branch conduits 19 and 21 each for admitting or withdrawing from one of two different fluids which flow without mixing in different ranges of the cross sectional area of the conduit 1 is characterized by having a block 2 clamped to the main conduit 1 upon which, at 8, may be hooked swingably a connecting member 14 having separate channels 19 and 21 opening from a contact surface 15 which by swinging the connecting member may engage with a corresponding contact surface of the block 2 into which opens the lateral channel 6 (or two channels communicating each with one fluid in the main conduit) to connect with the channels 19 and 21. As described, the conduit 1 is the main pipe from a teat cup of a milking machine. The pipe is horizontal with milk flowing in its lower half and a vacuum above it in the upper half of its cross-section. The channel 19 leads to a connector 16 for a milk discharge-tube and the channel 21 to a seat 23 upon which the teatcup pulsator 25 is removably received. A disc valve 26 and rubber seating washer 29 prevent reverse flow if the pressure in the pulsator falls below that in the conduit 1. When the member 14 is not hooked on the pivot pin 8 the channel 6 is closed by a valve plate 9, hinged at 12 on the pin 8, and normally in the position shown in Fig. 4. The member 14 is hooked on the pin 8 in an inclined position such that its left-hand long side lies along the face 31 of the valve 9 as seen in Fig. 4 and is allowed to fall to the vertical position as in Fig. 1 so that the surface 15 replaces the valve plate 9 over the channel 6 and connects its own channels 19 and 21 with it. Spring-loaded levers 33 ensure that the valve 9 and the member 14 are correctly positioned when they are covering the contact surface on the block 2. When the member 14 is swung away from the said surface it drags the plate 9 back to cover the channel 6.

Filed: 1916-11-28
Abstract: 112,962. Southey, A. W. Nov. 28, 1916. Spray carburettors. - Fuel, in excess of the quantity required by the engine, is sprayed through a comparatively large bore nozzle B, situated below the normal fuel level, into a mixing chamber A of large cross-section compared with the induction pipe. Owing to the reduction of the velocity of the mixture in the chamber A, the larger fuel particles, or those not taken up by the air, fall to the bottom of the chamber and return through an aperture G to the float chamber E and are used again, a constant circulation of fuel being set up. When at rest, fuel flows through the nozzle B and accumulates in the chamber A, choke tube C, and air inlet D to the level indicated by the dotted line. Additional air to form the explosive mixture is admitted through a valve in the end of the throttle valve F.

Title: Improvements in controlling mechanism for hydraulic motors
IPC: F41A9/03
Filed: 1944-09-06
Abstract: 591,864. Screw conveyers. NICHOLLS, K. H., TINDALE, J., GILBERT, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. Sept. 6, 1944, No. 17079. [Class 78(i)] [Also in Group XXI] In screw conveyers for feeding ammunition to a gun-loading station as described in Specifications 588,299 and 590,337, the oil driving motor 18 is controlled by a lever 25, 26, which is carried round by the conveyer shaft 16, and by an annular cam 28 secured to the stator of the motor. The hollow shaft 16 is coupled to the rotor 17 of the motor which is controlled by a sleeve valve (not shown) arranged to slide axially in a port member and having three operative positions, viz. forward, reverse and neutral. The lever 25, 26 is pivoted in a bearing 24 which is carried by a member freely mounted on an axial shank 22 provided on the sleeve valve. A roller 27 on the arm 26, when the latter is lowered, runs on the annular cam member 28 which carries a valve-operating cam 29. A pivoted link 31 connects the arm 25 to a lever 32 which is pivoted on the shaft 16 for movement about an axis parallel to that of the pivotal axis of the lever 25, 26. An operating rod 34 is slidably mounted in the, shaft 16 and its ends are provided with lugs 36, 37 for engagement respectively with the underside of the lever 32 and the upper side of a feeler arm 38 pivoted to the casing 11 about an axis normal to the axis of the conveyer. Since the sleeve valve is spring- urged downwardly towards the forward position, the arm 38 also is urged downwardly to the position it occupies when there is no charger at the loading station. When the leading charger strikes the feeler 39, the arm 38 rises and since it carries the rod 34 with it, the lever 32 rises and turns the lever 25, 26 about its pivot. When this occurs the roller 27 engages the track 28 and runs on it until it strikes the cam 29, whereupon the lever is turned about its pivotal connection with the link 31, the sleeve valve is lifted to neutral position, and the motor stops. The timing of the cam is such that the roller strikes it almost immediately after it drops on to the track. Should a slight over-run occur, the roller rides further up the cam, and the valve is moved into its reverse position with the result that a hunting motion of the motor takes place untilit stops in the predetermined circumferential position. The conveyer remains stationary until the leading charger is removed, whereupon the feeler 39 returns to normal position, the valve returns to the forward position and the conveyer starts again.

[Class 38 (iv)] Voltage; current, &c.-Two related quantities of which one is to be maintained constant so long as the other does not exceed a maximum value, are controlled by a regulator subject jointly to the said quantities, the currents controlling the regulator being derived from the respective quantities, at least one of them through a self-magnetised transductor (or saturable reactor having a retroactive magnetising winding), thus a voltage E, Fig. 1, may be maintained constant until a current I resulting therefrom reaches a maximum value to which it is limited by the action of the regulator. The regulator may itself be a transductor 3, Fig. 2, which has a selfmagnetising winding 33 and a constant current magnetising winding 32 opposed by a regulating winding 31. The winding 31 is excited by two transductors 1, 2 in parallel, the first being excited by a winding 12 in accordance with the voltage of a circuit to be regulated and the second by a winding 22 in accordance with the current in the regulated circuit. These excitations are opposed by a constant current in windings 11, 21 and assisted by self-magnetising windings 13, 23. In addition to regulation as set forth, the arrangement has an inherent tendency to positive compounding, counteracting the negative compounding due to the droop of the regulator. Specifications 462,385, 462,757 and 508,230 are referred to.
