Filed: 1966-06-22
Abstract: 1,177,811. Filter bed. PERMUTIT CO. Ltd. 21 June, 1967 [22 June, 1966], No. 27985/66. Heading BID. The reverse-flow washing cycle of a filter bed and restoration thereafter of normal downward filtration flow are controlled automatically by four float operated valves 4, 6, 8, 10 which respectively control inlet and outlet of water being filtered and inlet and outlet of backwashing water. Clogging of the bed 2 raises the water level to 17 which starts siphon 16, filling chamber 19 and hence opening valve 10 and draining off the water above the bed to waste 15. Pipe 9 exceeds pipe 15 in crosssection, and chamber 13 is able to overflow, so float 14 is raised and closes inlet valve 4. As the water in filter tank 1 falls, floats 11, 12 successively close the filtrate outlet and open backwashing inlet valve 8. The bed is then backwashed upwards. Chamber 19 has a small outlet 20 and acts as a timer for the backwashing cycle. After 5 minutes backwashing, float 21 has fallen sufficiently to close valve 10, so that the water level above the bed rises again to restore valves 6, 8 to open and closed positions. As chamber 13 empties valve 4 is opened again by descending float 14.

Title: Tube electrode
IPC: H01J19/00
Filed: 1963-07-15
Abstract: 1,033,369. Winding electron tube grids. SYLVANIA ELECTRIC PRODUCTS Inc. July 15, 1963 [July 20, 1962], No. 28000/63. Heading B3E. A method of producing a helix of wire, wound around at least two spaced side members and having a final tension in the wire which is substantially the same in all turns includes the step of applying to the wire during the winding of the helix a back-tension which is so programmed that in each turn at a position where the side members will be displaced by a subsequent turn or turns, the tension applied during winding is greater than the said final tension by an amount sufficient to compensate for the subsequent slackening of the turn being wound due to the said subsequent displacement of the side members. A frame 5, having side members and cross-straps, is mounted on a mandrel 25 and rotated by heads 21, 23 while wire 41 from a supply spool 63 is wound thereon, a wire guide 39 being moved longitudinally of the mandrel by a cam 29. The spool 63 is frictionally held by a shaft 65 of a back tension motor 55 driven through an amplifier 57 having a voltage control 59 having a variable contact arm 61. The arm 61 is moved by an arm 47 under control of a cam 51 so that the back tension on the wire so varies along the length of the mandrel 25 as to result in turns of constant tension being wound on the side rods 7 even when bowed inwards under the wire tension. The wire 41 being wound passes over a foil 67 disposed above an air exhaust vent 79, the wire supply being thus damped during each turn wound. Damping may be effected by electrostatic or magnetic force. The side members may be of molybdenum 0À02 to 0À055 inches thick and the wire of tungsten 0À001 to 0À006 inches in diameter.

Abstract: 454,815. Centrifugal separators. HERMANN, C. E., 813, Montgomery Street, St. Louis, Missouri, U.S.A. Oct. 11, 1935, No. 28119. [Class 23] A separator for pulverized material has inner and outer shells 27, 26, Fig. 4, mainly conical in form and having a common cover 35 ; the stream passes up the space 28 between the shells and passes through a series of adjustable vanes 44 to the inner shell, the vanes being arranged to form narrow and deep tangential inlets. The heavy material drops to the outlet 30 at the bottom of the shell 27 and the fine material is carried up to the discharge pipe 15. An extending sleeve 37 inside this pipe may be lowered into the separator, to vary the degree of separation, by means of the handles 39 on the supporting bars 38. As the sleeve is moved upwards it passes under a fixed sleeve 41 which is secured at its upper end to the pipe 15. The bars 38 are perforated to receive locking pins 40 so that the extending sleeve 37 may be fixed in any desired position. Stiffening rings 45, 46 are provided at the cylindrical parts of the shells and are connected by a number of spacers 47. A flanged ring 48 is secured to the ring 45 and has a number of apertures which receive the lower pivots of the vanes 44. The upper pivots 50 project through the top plate 35 and are fixed to the outer ends of arms 52. Each arm has a slot 54 through which extends a pin 55 attached to a ring 56 mounted on bearings so that its rotation swings the arms 52 and varies the positions of the vanes 44. Operating arms 58 attached to the ring 56 carry brackets 59 engaging one end of a doublethreaded screw 62, the other end of which engages a fixed bracket 60. The central part of the screw is hexagonal to permit adjustment and has holes 67 so that it can be locked by a pin forming part of a latch 64. Access to the interior of the separator can be obtained by removing a closure plate in the top plate. The flow through the apparatus may be maintained by a suction fan on the pipe 15, and the gas withdrawn may be passed to a cyclone separator for the separation of the fine material. In the modification shown in Fig. 9, the apparatus is enclosed by a casing 74, while the inner and outer shells 79, 75 are supplied with material from the funnel 84 and the hollow shaft 81. The shaft is rotated from the belt 87 by means of the auxiliary shaft 85, and carries a fan 80 for withdrawing air and fine material through the pipe 78, to discharge it through the outlet 77 at the bottom of the casing. The material from the hollow shaft passes to the rotating disc 99, then moves upwards between the shells, and between the adjustable vanes to the inner chamber. The separated heavy particles drop to the outlets 86 and then pass to the rotating cup 91 and outlet pipe 94. An annular space 104 is formed between the two walls 101, 102 of the outer shell and is provided with radial vanes 106.

Abstract: 408,665. Coin-freed article-delivery apparatus. SHERMAN, H., 40, Bancroft Road, Mile End, London. Oct. 12, 1932, No. 28449. [Class 27.] Coin action, mechanical - connection. -In a coin-freed vending machine in which the bottom article of a stack is delivered by a recessed roller, the roller shaft 33, Fig. 2, has fixed to it a four-armed spider 61, the part 63 between the arms being arcuate. A coin 67 inserted in a shoot 5 rests between two arms 77, 79 as shown, so that when the shaft 33 is turned by hand in the direction of the arrow, the arm 79 presses the coin against a lever 65. The lever 65 is rocked and through a link 75 rocks a detent 69 out of the path of another arm 73 of the spider, thus allowing the shaft 33 to be rotated through a quarter-turn, to deliver a packet. The coin is forced by the arm 79 down to a money-box 81 and the detent 69 again locks the shaft. A pawl engaging a ratchet wheel on the other end of the shaft prevents backward rotation. Returning coin.-A rocking lever 87 with a sloping top 89 is moved by the coin 67 into the shoot 5 so that if a second coin 90 be inserted before the first is discharged, this second coin is deflected laterally out of the shoot 5 to the goods delivery opening. Articles stored in piles.-The machine has two delivering rollers, one with four recesses to deliver an article at each quarter-revolution of the shaft 33, and the other with one recess to deliver an extra or '' gift " article from a second stack at every fourth actuation of the machine. Each recess in the roller has a rear wall 41, Fig. 4, at right angles to a bottom 43, this wall 41 pushing the lowest packet 27 past a spring-pressed flap 23, into a shoot 49 leading to a delivery opening 7.
