Abstract: 232,687. Rhodes, C. J., and Berry, G. W. Jan. 24, 1924. Seaming.-A machine, for seaming sheet-metal, particularly for applying bases to rectangular biscuit tins &c. comprises a press having cooperating dies b, k the upper of which is reciprocated by a crank-shaft d driven through gearing and a one-revolution clutch of ordinary construction. The lower die b is recessed at b<2> to accommodate the can body, which is previously flanged and is supported on springs e. A previously dished base is placed on the can &c. so as to rest on a ring f, Fig. 5, which is resiliently supported by spring plungers f<1> and is positioned by wedge members j urged radially outwards by springs. The work is held during seaming by internal dies h<1> which are moved radially against spring pressure, as guided by screws h', by wedges h coacting with a central wedge member g<4> under the control of a cam g on the crank-shaft. The press head c is provided with adjustable cams i which have faces engaging the outer faces of the wedges j so as to retain the ring f stationary while the base flange is flattened to form the seam. On further descent of the press head the cams i allow the wedges j to move radially outwards, thereby permitting the ring f to descend under the pressure of the upper die while the latter folds the seam against the can body. The upper die may be built up of boundary die-surfaces k<1> enclosing a resiliently mounted work pressure plate k.

Abstract: 913,991. Control systems for resistancewelding apparatus. WELTRONIC CO. Jan. 20, 1959 [Jan. 28, 1958], No. 2069/59. Drawings to Specification. Class 38 (4). Resistance-welding equipment comprising a welding transformer which is controllably energized from a source of alternating current of reversely connected pairs of ignitrons, each of which ignitrons is provided with a thyratroncontrolled firing circuit, has each of the series of sequential operations which comprise a resistance - welding operation controlled by means of a device which initiates the operation and controls its duration. The device comprises a large number of electronic multivibrators, both double and single state, and a number of multi-cathode, cold-cathode counting tubes which time the duration of each of the sequentially arranged operations by counting a series of pulses which are derived from the alternating current supply. A further device is provided which terminates the welding operation should the A.C. supply voltage deviate by more than a given amount from its nominal value. If certain parts of the equipment are pneumatically operated, the latter device may also terminate the welding operation if the air pressure is outside prescribed limits. Phaseshifting circuits are associated with the thyratron controlled firing circuits to improve the control of the welding equipment. When more than one group of ignitrons is used to control the welding equipment, means are provided to shorten the decay period of the current at the end of each half-cycle of the A.C. supply. The equipment may be arranged for full cycle welding, for positive half-cycle or negative half-cycle welding.

Abstract: 1,122,071. Continuous casting machines. ALBERT MANN ENG. CO. Ltd. 19 April, 1966 [19 Jan., 1965], No. 2370/65. Heading B3F. In a rotary continuous casting machine in which a grooved casting wheel co-operates with an endless belt 3 to form a mould cavity, the depth of the casting groove is varied progressively around the circumference of the wheel, the groove having a floor and side walls relatively movable to the floor whereby the depth of the groove at any point on the circumference of the wheel, is constant during rotation of the wheel, the point remaining fixed in space during the wheel rotation. The wheel is of composite construction formed by a cylindrical member 8 located between two outer cylindrical members 9, 10, the intermediate member 8 being of smaller diameter than the outer members so that in combination they form a peripheral casting groove the base of which is defined by the member 8. The outer members 9, 10 are respectively mounted on bushes 20, 21 on shaft portions 23, 24 on a common axis of rotation 27. The intermediate member 8 is mounted on an eccentric bush 19 on a shaft portion 22 whose axis 26 is offset from the axis 27 of the two outer members. The bush 19 is angularly adjustable so that the extent of variation of the depth of the casting groove may be varied. The wheel members are provided with respective ducts 28, 29 and 30 for the passage of coolant and coolant may also be sprayed (as shown by reference numeral 38) on the wheel and belt when casting is in operation. The effect of varying the depth of the casting groove permits the casting to always be maintained in contact with the base of the groove irrespective of any shrinkage that occurs during the cooling of the casting.

An arrangement for suppressing the excitation of one or more high-reactance polyphase synchronous alternators acting as a single alternator when in parallel, comprises relays 12-14 connected to bus-bars 6 which release contacts 15 at a determined drop in voltage, disconnecting the supply from a battery 33 to voltage regulators 36. Self-holding contacts 18-20 also open at the same time. Removal of the excitation causes the bus-bar voltage to drop which releases also relays 9-11 energizing a spring-loaded motor which closes the contacts 15-17, and connects the voltage regulators to a lower voltage tap 34 on the battery through contacts 27-29. As soon as the bus-bar voltage rises 15% above a quarter to a third of the normal value, relays 9-11 are operated which disconnects the motor 30, permitting a spring 31 to restore the circuit to normal by reconnecting the full battery voltage to the regulators through contacts 26, 27, 29. Another arrangement is described suitable for use with alternators having shunt-excited exciters. Specification 823,798 is referred to.
