Title: Improvements relating to rectifier/inverter equipment
Inventor: KEMP HENRY
IPC: H02H7/12
Filed: 1959-07-30
Abstract: 894,563. Protective cut-out arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 24, 1960 [July 30, 1959], No. 26196/59. Class 38 (o). [Also in Group XXXV] In a rectifier/inverter equipment having polyphase voltage transforming means T1, T2 in combination with a plurality of grid-controlled gaseous-conductor valves V1  . . . V10, means are provided for deriving an electrical quantity which varies in dependence upon the algebraic difference between currents flowing simultaneously in at least two anode - cathode paths of the equipment, switching means responding when the quantity reaches a value signifying a " breakthrough " fault in one of the paths when the equipment is inverting. The switching means may also respond when the quantity reaches a value signifying a " backfire " fault in one of the paths when the equipment is rectifying. In Fig. 1 the six output phases of each of the transformers T1, T2 are applied to the anodes of five six-anode mercury-arc valves V1 . . . V5 and V6 . . . V10, respectively, the valves being arranged in pairs, one from each group of five. The cathode connections of the two valves in each pair provide differentially arranged D.C. control conductors CC of a saturable core reactance device RD having A.C. windings AC1, AC2 supplied from a transformer T3 in series with a bridge rectifier RF connected to the trip coil TC of circuitbreaker XB. Under normal conditions the currents in each pair of control conductors CC are of the same magnitude so that the core of each device RD is not saturated and the associated A.C. windings AC1, AC2 have a high impedance preventing the energization of the trip coil TC. In the event of a fault in either valve of a pair of valves, the currents in the associated control conductors CC will differ, causing the core of the device RD to be magnetized so reducing the impedance of the A.C. windings AC1, AC2 and causing the tripping of the circuit-breaker XB to cut-out the affected pair of valves. Fig. 2 (not shown) illustrates an arrangement for a small number of valves in which only the faulty valve is disconnected. In this case the control conductors CC are located in the anode connections of the valves.

Title: Apparatus for making vehicle tire casings
IPC: B29D30/36
Filed: 1926-10-21
Abstract: 260,282. Morgan & Wright, (Assignees of Abbott, A. O.). Oct. 22, 1925, [Convention date]. Moulding wheel tyres.-Relates to vacuum apparatus for shaping tyre casings from a " pulley band " as described in Specification 220,290, and comprises an annular vacuum chamber having on one or each of its inwardly-extending walls a radially-adjustable ring of variable girth adapted to centre the tyre and to form an initial seal and obviate the preliminary bulging step. Figs. 2 and 5 show one form of apparatus comprising a cylindrical casing 15 supported on a framework and co-operating with a counterweighted, hinged cover 21. A bottom wall 23 is adjustably supported within the casing upon screws 25 operable simultaneously througn handwheels 28 and a chain 29. A table 32 for supporting and centering the tyre 100 is supported by slots 31. Mounted upon the cover 22 are a series of overlapping sectors 39 having a cut-away portion 41 engaged by a depending rib on the adjacent sector. The sectors are guided radially by a pin 44 and groove 43 and are operated by a ring 45 furnished with cam slots 46 engaging pins 47, the ring being guided by posts 48 and furnished with an operating-handle 49. A similar series of sectors and operating-ring are mounted below the bottom wall 23, the ring being furnished with an operating-handle 62 which works in a reverse direction to the handle 49. In operation, the bottom wall 23 and table 32 are adjusted and the tyre placed in position after which the handles 49, 62 are moved towards each other forcing the sectors into contact with the tyre, thereby forming a seal. The vacuum chamber is then exhausted through a pipe 63 and as the tyre is drawn into the chamber, the sectors are forced back until the tyre contacts with the lips 50. A core is then introduced as described in the prior Specification. Fig. 8 shows a modification in which the hinged upper wall 73 is fitted with sectors 82 pressed radially inwards by springs, the bottom wall 72 being connected by a bellows 84 to a table 86 supporting the tyre 105 and adjustable by a screw 87 to centre the tyre. A casing 88 supports the chamber, apertures 89 being formed in the table 86 so that the space beneath it remains at atmospheric pressure. Either the spring sectors or the bellows may be used on the top and bottom walls.

Abstract: 407,417. Treatment of growing plants; grafting. CASE RESEARCH LABORATORY, Inc., 203, Genesee Street, Auburn, New York, U.S.A.-(Assignees of Case, T. W., and Crysdale, S. A. ; Auburn, New York, U.S.A.) Sept. 29, 1932, No. 27042. Convention date, Aug. 25. [Class 6 (ii).] A method of treating a tree having a section of bark removed consists in inserting scions or living twigs in the space from which the bark has been removed with their ends in intimate contact with the edge of the bark, and enclosing the scions in a jacket which is water-proof and air-proof and preferably light-tight. The ends of the scions 5 are made wedge-shaped and are fitted into corresponding recesses in the edges of the bark, the scions and the junctures being coated with grafting wax and the scions being secured in position by nails &c. The bark of the scions is slit longitudinally on opposite sides to encourage the growth of calouses, the edges of the bark of the tree also being slit. The whole is washed with a formaldehyde solution or other sterilizing fluid, and then covered with layers of cheese-cloth 9 or the like wound round the tree, with taping 10 at the upper and lower edges. The cover is finally impregnated and coated with an emulsion of asphalt material 12 or other waterproof material. A thin layer 11 of damp surgical cotton or the like may be inserted between the scions and the cheese-cloth. In another arrangement the wedge-shaped ends of the scions are forced under the adjacent edges of the bark. Suckers on the tree may be used instead of scions, their upper ends being cut and brought into intimate contact with the bark. Specification 407,416 is referred to.

Abstract: 620,169. Counting-apparatus. PRODUCTION INSTRUMENT CO. Sept. 11, 1946, No. 27311. Convention date, Oct. 16, 1945. [Class 106 (i)] [Also in Group XXXVII] Articles to be counted are carried by a conveyer belt movable in an open channel and are forced through a restricted passageway formed in the channel by means of a drive member or wheel and a yieldable control member, the displacement of which serves to actuate a counting mechanism. The control member operates a switch (see Group XXXVII) to send impulses to the counting device that controls a distributer means to direct predetermined numbers of articles into one or the other of delivery shoots. As applied to the counting and packaging of bottle caps 40, Figs. 1 and 2, the caps are deposited on a conveyer belt 13 in a trough-like channel and are directed by an adjustable deflector plate 31 to a passageway formed by a drive wheel 17 and a spring control member 36 adapted to operate a switch 35. The wheel 17 is driven by a belt or chain from a flexible drive shaft 29, the unit being mounted in a strip 21 on an extension of the channel member 11 for lateral and angular adjustment depending on size of cap. The control member 36 is anchored to the switch housing and extends through a slot in the side wall 12 into the feed channel and is formed at its free end with a hook 38 to permit lateral movement. On depression, the member 36 closes contacts 57, 58, Fig. 8, in a circuit 41 to transmit an impulse, on the passage of each cap, to a counting device P.C. After a predetermined count, a relay 100 operates contacts 101 to energize one or other of a pair of solenoids 50, 51 to deflect a gate 46 to discharge the caps through one or other shoot 44, 45, Fig. 1.
