Title: Improvements in and relating to the concentration of dispersions or emulsions
IPC: C08C1/10
Filed: 1931-12-10
Abstract: 393,644. Centrifugal machines. RICHARDSON, E. M., 25, Woolwich Common, London. Dec. 10, 1931, Nos. 34238/31 and 26251/32. [Class 23.] Rubber latex and like dispersions having a disperse phase lighter than the continuous, are concentrated by subjecting them to the action of a centrifugal field in apparatus comprising a filter drum whereby the disperse phase moves inwardly away from the filter, and thus does not clog it, and only the continuous phase passes through. A bowl 6 having peripheral grooves 30 leading to discharge openings 31 and an inner filtering layer 15, is mounted on a spindle 2 by means of a cap 7 and nut 9. The spindle is carried in a yoke 12 having a detachable cover 13 to allow of removal of the bowl 6 and filter. Latex is fed by a pipe 26 to a chamber 22, and thence by a bore 20 in the spindle 2 into the apparatus. On rotation the rubber particles crowd inwards, and the serum passes through the filter to the grooves 30 and is collected in a trough 32. Ammonia may be introduced into the concentrate through a passage 38 in the spindle. On completion of the operation, the concentrate is withdrawn through the bore 20 and pipe 27. By providing outlets 45 in the upper cap, and a trough 47, the operation may be made continuous. In this case, a film of resin from the latex, retained on the filter, serves as a lubricant and assists the upward passage of the concentrate.

Title: Feed mechanism for transfer machine
Inventor: JACKMAN PAUL
IPC: B65G59/02
Filed: 1962-09-10
Abstract: 974,261. Feeding nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 2, 1963 [Sept. 10, 1962], No. 34510/62. Heading B8S. Nuclear fuel elements 1 in a magazine 3 are pressed upwards by piston 4 actuated by motor 6 through rack and pinion 5 and the topmost element is discharged by reciprocating pusher 11, the element falling on to discharge conveyer 14. The elements differ in thickness and their movement and position is controlled by light beam 8. Light beam 8 controls the control 7 of motor 6 such that when the light beam is obstructed the pusher 11 operates and when the light beam 8 is not obstructed the motor 6 operates to elevate the stack of elements 1 in the magazine 3. The piston 10 of pusher 11 is caused to reciprocate by rotating cam 18, the depressions b of which engage follower 17 on pivoted arm 16 connected to rod 10. Lever 16, however, oscillates under the control of light beam 8, the control being effected through solenoid 21, the armature 22 of which engages in aperture 23 formed on extension 24 of arm 16. When armature 22 is withdrawn from aperture 23 by the operation of solenoid 21 effected by light beam 8, the lever 16 is free to oscillate under the control of cam 18 and to cause the pusher 11 to operate. The oscillation of lever 16 is further governed by switch 19 included in the motor circuit, the follower 19a of which engages cam 20 concentric with cam 18. This avoids the too-sudden operation of piston 10 in the case when armature 22 is withdrawn whilst follower 17 is exactly opposite a depression b.

IPC: B21D43/00
Filed: 1954-11-30
Abstract: 785,716. Feed mechanism for presses. BLAKE, W. A., [trading as B.H.P. MACHINE TOOL CO.]. Nov. 30, 1955 [Nov. 30, 1954], No. 34602/54. Class 83 (4). A feed mechanism for a power press or the like, comprises an oscillating arm 10, Fig. 5, with a pick-up head 35 adapted to transfer a workpiece from a supply position to the press die or the like 12, the pick-up head being controlled automatically, for picking up or releasing the workpiece, in accordance with the position of the arm 10, and setting control means 49 are provided for permanently activating the pick-up head to retain a workpiece thereon during setting up or resetting of the mechanism. The arm 10 is adjustably clamped to a sleeve 14 keyed to a spindle 15, Fig. 3, but axially slidable thereon and biased upwardly by a spring 24. A lug 16, Fig. 5, is rigidly secured to the spindle 15 and is connected through a spring-biased lost-motion connection with a rod 17 connected to a slide 18 actuated through linkage 21, 23, Fig. 1 (not shown) from the main crankshaft of the press. The arm 10 is lowered at each end of its oscillating movement, which is limited by adjustable stops 32, 33, Fig. 2 (not shown), by a pivoted lever 27, Fig. 3, having rollers 26 engaging a flange 25 on the sleeve and a roller 29 actuated alternately by cams 30, 31 on the slide 18. The pick-up head may comprise a suction cup, a pair of gripper fingers operated pneumatically or hydraulically or on electromagnetic head. In the embodiment of Fig. 5 the head may be operated alternatively by suction or air pressure. Suction is effected by a pump 36 acting through pipe 39 on valve box 38; pressure air is also supplied to the valve box through pipe 41, lubricator 42 and reduction valve 43. A control handle 46 selects whether air or vacuum shall be supplied through outlet pipe 47 and shut-off valve 48 to the head 35. The supply to the head is controlled by a valve toggle 37 actuated by cams 50, 51 on the slide 18. A by-pass valve 49 enables air or vacuum to be supplied permanently to the head during setting of the mechanism. The valve 49 is preferably housed in the valve box 38. When the head is electromagnetic, it is controlled by switches instead of valves 38, 49.

Title: Improvements in or relating to an electric circuit arrangement for the simultaneous transmission of a plurality of communications
IPC: H04J3/10
Filed: 1953-02-02
Abstract: 771,059. Automatic exchange systems. SIEMENS & HALSKE AKT.-GES. Feb. 2, 1953 [Feb. 1, 1952], No. 34605/55. Divided out of 771,058. Class 40 (4). [Also in Group XL (c)] In a time division multiplex transmission system, in which communications are established over a common path by applying gating pulses to input and output gates at the ends of the path, only pulses amplitude-modulated by signals such as speech can pass through the output gate. Each subscriber Tn1 ... Tn4, Fig. 1, is connected by a four-wire termination G1 ... G4, a combined modulator and input gate PAM1 ... PAM4, an output gate ET1 ... ET4 and a demodulator T1 ... T4 to both ends ME, MA of a common path. When a subscriber, say Tn1, makes a call, a switch PZ1 associated with the caller connects gating pulses, say P1, corresponding to an idle channel to the output and input gates PAM1, ET1, respectively. In response to signals from the caller indicating the required subscriber, say Tn4, a connecting device WE sets a switch PZ4 to apply gating pulses P1 to the input and output gates PAM4, ET4. The gating pulses P1 are applied to the grid of tube RO1, Fig. 2, of the input gate PAM1 which causes small positive pulses to be fed to the grids of a normally cut-off tube RO2 and a normally conducting tube RO3, so that small positive or negative pulses according to the values of resistances Wi5, Wi6 are applied to the common path 3. These pulses may serve to signal to equipment, e.g. the connecting device WE, that the seized channel is busy. When speech from the caller reaches an input 1, it is rectified and up-biases the grid of tube RO1 so that tube RO3 transmits large positive pulses over the common path 3. The speech is also fed to the grid of tube RO2 so that the output of R03 is modulated accordingly. The negative gating pulses are also applied to the cathode of the input gate ET4, Fig. 3, of the called subscriber, the grid of which is backbiased so that only the large positive pulses cause ET4 to conduct. The output of ET4 is fed through a low-pass filter T and an amplifier V to the called subscriber Tn4. Speech is similarly transmitted in the reverse direction. The common path may be a line or a radio link. In a modification, the bias for the tube RO1 is derived from the peaks of the speech current.

Abstract: 888,817. Endless conveyers. F.M.C. CORPORATION. Oct. 14, 1959 [Dec. 10, 1958], No. 34791/59. Class 78 (1). Cartons C having outwardly-projecting end flaps F, F<SP>1</SP> are advanced by means of a feed conveyer 12 on to support surfaces 118 of a spacing conveyer 14, the leading carton thereon being advanced by the following cartons until temporarily stopped by the engagement of the leading edge of the lower flap F with a shoe 18 which is urged about a pivot 124<SP>1</SP> against plate 118 by means of a spring 133 with sufficient pressure to allow the carton past only when the carton is driven by lugs 16 which are spaced at predetermined intervals along the endless chains 74, 76 of the spacing conveyer 14. The cartons are thus fed at predetermined spacings from the conveyer 14 to the conveyer 20 of a carton closing machine 8, any cartons which are raised out of the normal position at the end of conveyer 14 being detected by means of an arm 170 secured to a rotatable shaft 172 which is provided with an arm to actuate a switch which cuts out the drive to the conveyers 12, 14, 20. The cartons are guided by means of guide plates 24, 26, and guides 116, 116a which are adjustable by means of bolts 162 and a screw 152 and which are provided with abutments 146 to arrest a carton which has been raised on top of a pair of lugs 16 until these lugs have passed from undereneath the carton and the following lugs engage the carton in the normal manner. Endless chains 56, 58 of the conveyer 12 are tensioned by means of a spring 50 which is compressed between a fixed cross member 38 provided with a splined aperture through which a splined rod 40 passes, and an abutment 52 on the rod, the rod being secured to a bearing block 42 for a shaft 44 which carries sprockets 46, 48.

Title: Improvements relating to liquid fuel burners
IPC: F23D99/00
Filed: 1921-12-28
Abstract: 191,279. Howden & Co., Ltd., J., and Hume, C. W. Dec. 28, 1921. Locking.-The hand wheel 4 on a pinching- screw 3 securing a liquid-fuel burner 1 in its holder 2 is prevented from being turned to release the burner except when the fuel supply valve 5 is closed by the engagement with its outer face of a tongue 12 on a hand-lever 11 operating the valve. When the pinching-screw has been operated to release the burner, the hand wheel prevents the operation of the hand-lever to open the valve. The hand-lever operates the valve through a spindle 6 which is mounted in a guide 7 on the holder 2 and is divided into two separable parts at 17. The lower spindle part is formed with a polygonal socket 8 engaging the polygonal end 9 of the fuel valve stem 10 and is fitted with a stop ring 15 engaging a shoulder 16 on the guide 7 to limit the movement of the spindle. The hand-lever 11 and the upper part of the spindle 6 are connected telescopically by means of a polygonal socket and projection and may be adjusted to provide for variations in the setting of the pinching-screw by means of a turnbuckle 13. The removal of the hand-lever 11 is prevented, when the valve is open, by the engagement of a pin on the spindle 6 with a perforated lug 19 fixed to the guide 7. A slot 20 in the lug permits the passage of the pin when the valve is closed. A pointer 21 on the spindle 6 indicates the position of the valve on a dial 14. An additional tongue may be formed on the lever 11 to engage the inner face of the hand-wheel 4.

Abstract: 1,004,750. Centrifugal pulverizers ; pneumatic separators. BATH IRON WORKS CORPORATION. Aug. 25, 1964, No. 34820/64. Headings B2A and B2H. A centrifugal pulverizer for reducing rock, pigments, clay, &c., comprises a cylindrical housing 20 with a cover 21, a bowl 32 rotatable by a spindle 27 at e.g. 300-450 r.p.m. and an impeller 40 rotatable at a higher speed by a spindle 26 e.g. at 2350-3600 r.p.m.; the spindles may be driven in opposite directions. An annular recess 38 is provided in an impactor ring 34, forming the inclined wall of the bowl, whose upper edge forms with the inner wall of the housing an opening 39, and the bowl has vents 37 in its floor. The casing contains lower and upper stationary cones 45, 57 axially supported by radially-disposed, spaced-apart arcuate, directional vanes 51, which direct large particles of material back to the impeller for further pulverizing. The lower portion of the. lower cone 45 extends down into the bowl, and terminates above a central opening 46 of the impeller, and the lower portion 58 of the upper cone 57 is cylindrical, extends within the lower cone and also terminates above the impeller opening. A vertically, axially-disposed feed tube 23 extends through the cover, and the upper and lower cones to a point above the opening 46 and is surrounded by a concentric outlet tube 22. Classification vanes 55 mounted below the cover 21 and spaced around it adjacent the upper edge of the upper cone, are adjustable from radial positions to positions forming an acute angle with the original radial positions. Air, forced into the housing via a duct 52 by a compressor (not shown), divides into two paths, one 60 upwards through the vents 37, along the inner wall of the bowl, and the other 61 upward along the outside of the bowl and through the annular opening 39 between the upper edge of the bowl and the inner wall of the housing, and then recombines and passes upward along the outer wall of the upper cone inward into the upper cone, then upward and out through the conduit 22. This division of the air stream keeps the housing wall above the bowl clear of clogging particles. The radial position of the classification vanes 55 controls the path of inward flow of air into the upper zone, and the particle size of material carried out of the tube 22. Particle size is also governed by adjustment of a sleeve 56 vertically in the discharge tube 22. In a modification, a double-deck impeller co-operates with an impact ring having two recesses so that particles returning to the impeller via the lower cone are returned to the upper desk and particles fed to the impeller from the feed shoot or returned to the impeller via the upper cone are returned to the lower deck.

Title: Improvements in or relating to windings for dynamo-electric machines
IPC: H02K23/38
Filed: 1932-01-08
Abstract: 394,719. Dynamo-electric machines. STRITZL, P. F., 6, Brentfield Gardens, Hendon Way, London. Jan. 8, 1932, No. 34912/31. [Class 35.] Cores; windings.-In a dynamo-electric machine a winding arranged in open or closed slots has the front or back pitch exactly or nearly equal to double the pole pitch of the field in which the winding acts or to an integral multiple (including zero) of double the pole pitch, and permeable members are disposed so as to provide a flux path between the working faces of adjacent main field poles, a part of the path having a higher reluctance than another part; both front and back pitches may be arranged as double pitch windings but the case in which both part pitches are exactly equal to an integral multiple of double the field pole pitch is excluded. Fig. 1 shows a winding in which one pitch is approximately equal to double the pole pitch of the field, and Fig. 3 shows part of the field and armature 3 of a continuous current motor. The nett effective current is zero in slots a, c, d, e, g, h and the slots b, f which have effective current are situated in the position of maximum field strength. The brushes 4 are located opposite the centres of the main poles. Interpoles 5 arranged between the main poles 2 provide an additional path for the armature flux, undue leakage being. prevented by the spacing between the poles. The interpoles may carry shunt, series or compound windings which assist the armature field. Instead of the interpoles, the tips of adjacent main poles may constitute the permeable bridge. The windings described may be applied to the stator or rotor or to both as open or closed coil windings and may be wave or lap-connected.
