Filed: 1946-05-24
Abstract: 613,083. Winding &c. wire &c. ARNOLD, J. C. (Vaughn Machinery Co.). May 24, 1946, No. 15879. [Class 120(ii)] Also in Groups XXVI and XXXV] Wire is wound on a driven take-ur spool 4, at substantially constant lineal speed, by mechanism including a centrifugal governor 38, driven by a pulley 39, about which the wire travels, the governor, through a micro-switch 37 energising a solenoid 35 when the speed of the wire increases, tc depress a spring. urged rod 30 to move a ball-valve 19 from its seating in the partition 16 of a liquid containing cylinder 15 to allow a strong compression spring 26 to move a piston 23 upwardly. In its motion upwardly the piston rod 24 takes with it an arm 14 so that belts 8, 9, driving the spool shaft 5 from the drawing drum shaft 7, shift in regard to conical pulleys 12 to lower the rotary speed of the shaft 5. Upon the speed being lowered, the shaft of the governor 38 moves from the micro-switch 37 to allow the valve 19 to close and so lock the pulleys 12 in the adjusted position. In a modification, Fig. 4, the governor 38 is dispensed with. the wire being drawn around a pulley 55 on a spring pressed arm 56 which, on the wire tension increasing, is depressed to actuate a link and lever system 58 to depress the rod 59 to unseat the valve 19 and so allow the arm 14 to adjust the drive ratio to the spool shaft 5. The governor 38 comprises a bar 46 split longitudinally intermediate its ends in a median plane to provide two limbs and provided with journals 47, 48. Shoulders on the governor rotor and a spring 53, allow only of movement of the rotor end 54 which, upon increase of speed, moves to the left away from the micro-switch 37. A foot pedal 29 through a link and lever system 28, 27 enables the operative to reset the piston 23 in the cylinder 15 for a fresh wind. U.S.A. Specification 2,243,480 is referred to.

Abstract: 576,329. Percolating filters for sewage and other foul liquors. HARTLEY, C. J. Oct. 2, 1943, Nos. 16191 and 21512. [Class 46] A percolating filter for sewage or other foul liquors or trade wastes is aerated by a fan or other means blowing air into, or exhausting air from, a covered channel centrally arranged in the bottom of the filter and communicating with the under-drains of the filter which channel serves also as the effluent discharge channel, being provided at the discharge end with a liquid-trap air seal. Alternatively the aerating air may be supplied to a peripheral pipe communicating with the outer ends of the under-drains, the effluent discharge channel being as above. As shown in sectional elevation. Fig. 1, and plan, Fig. 2, sewage is distributed by a rotating arm 27 over bricks 32 laid honeycomb fashion in a circular tank 20 to provide filtering clearances and the filtered liquid drains away through under-drains 29 formed by half-round tiles to a covered diametral channel or well 28, closed at one end and having a liquid-trap air seal 34, Fig. 3, at the other end. The usual rotary distributing arm 27 is supported on a hollow central pedestal 21 which is formed over and in communication with the covered channel 28 and into which air is blown by a fan 30 to pass to the under-drains 29 and so upwards through the liquid being filtered. The ducts are shown extending at right angles from the diametral channel 28 but may be arranged radially or in herring bone manner The liquid seal is of such height that it is not broken by the air pressure and the filtered liquid passes away by the effluent pipe 38. The top of the filtering tank may be enclosed by a roof, heating arrangements provided,-and the air may be re-circulated with any necessary air admitted by a valve to make up for the exhaustion of the oxygen. The. percolating tanks may be subdivided with valve arrangements to control the air supply to the separate sections.

Patent GB-627799-A (GB)
Title: Improved means for controlling automatically the speed of take-up of an electric cable or other member undergoing a manufacturing process
IPC: H01B13/00
Filed: 1947-06-20
Abstract: 627,799. Automatic control systems for positioning. SOUTHERN UNITED TELEPHONE CABLES, Ltd., and MACKENZIE, W. A. June 20, 1947, No. 16365. [Class 38 (iv)] [Also in Group XXIV] Relates to apparatus in which a long continuous member such as an electric cable is fed from a machine, and the speed of take-up is' controlled by relays so that the depth of the hanging loop is constant. According to the invention, the speed is controlled by axial movement of a shaft which is rotated at a constant speed, and has a right-hand and a left-hand worm, each engaging an associated. worm-wheel which normally runs free but may be restrained by a brake under the control of one of the relays, thereby imparting an axial movement to the shaft. A system is described in which two light rays and co-operating photoelectric cells are placed at the limiting positions of the hanging loop of cable, so that when the cable obscures one of the cells an associated relay is operated. Rollers are provided to prevent the cables passing through the light rays. In Fig. 2, the shaft 13 which is movable along its axis, is rotated at a constant speed by means of motor 12. The right-hand and left-hand worms 16 and 17 drive wheels 18 and 19 which are normally free running. The two relays associated with the photo-electric cells energize one of the solenoids 25 which applies a brake 23 either to wheel 18 or wheel 19 according to which relay is operated, and thus moves shaft 13 axially in one direction or the other. This causes wheel 28 which is engaged with circular rack 27, to rotate and this is used to control the speed of the hydraulic motor or other device used to take up the cable, in a direction such that the depth of the hanging loop is restored to the required value. The gear ratios of the two worm gears may be made different, to reduce any tendency to hunt.

Filed: 1926-06-29
Abstract: 278,076. Standard Telephones & Cables, Ltd., (Deakin, G.). June 29, 1926. Automatic and semi-automatic exchange selectors and associated apparatus.- In a rotary switch of the type in which one of several sets of brushes is selected to engage a corresponding row of terminals, resilient brushes which, when free, are out of the path of the terminals, are selectively forced into the said path by cam-means mounted to rotate co-axially with the brush-carriage both relative thereto and together with the said carriage by a single driving wheel. Arrangements of terminal banks and multipling are also described. The brushes 21, Fig. 3 are mounted in a vertical row on a frame 4 rotatably mounted on the shaft 3, and have cam-terminal- and stop-engaging points 59, 61, 60. The cams 24 are mounted in staggered relation on a frame 5 fixed to the shaft 3, which is driven by a flexible gear wheel 10 from a driving- shaft 8, under the control of the armature 53 of a magnet 6. The cams 24 of insulating material each carry wires 26A, B, C which contact with the brushes and are multipled to the commutator 28, which engages brushes 121. In operating the switch, the magnet 7 is first energized, so that its armature 45 operates a catch 40 pivoted to the brush-carriage 4 to engage a slot in the switchframe and to remove it from engagement with a gear-wheel 30 fixed to the shaft 3. The magnet 6 is now energized so that the shaft 3 and the cam-frame 5 are rotated. When the required brushes are operated by their cams. the magnet 7 is de-energized so that the catch 40 locks the brush-frame to the shaft 3, and the selected brushes are rotated in engagement with their contacts to the required position, when the magnet 6 is de-energixed. Commutator segments 29, 52 and their brushes 122, 123, are used to send back revertive impulses as required. To return to normal, magnet 6 is again energized and the frames 4, 5 are rotated until the brushframe 4 reaches normal, when the magnet 7 is energized, and the frame 5 continues alone round to its normal position again, when both magnets de-energize. The brush-blocks may be staggered instead of the cams, and the brush-frame may perform the brush-selecting movement. The brushes themselves may be multipled to a commutator on the frame 4. The brushes may be hinged and normally retracted by springs, while push-rods or the brushes themselves may engage cams on the shaft 3. The Provisional Specification also describes the method of mounting the shaft 3 and means for automatically spacing the cam units when assembling. Terminal banks. The terminals may comprise metal strips 102, Fig. 7 having lugs which engage slots in an insulating block 100 and are bent or riveted in position. The brush-engaging ends of the terminals may be bent down to give a larger surface, while the 'test terminal may be narrower than the line terminals. Ribbon cable 106 may be attached to the terminals in a reversed position. so that the outside edge of the folded-over portion meets the terminals.
