Abstract: 761,996. Making radiators. FORD MOTOR CO., Ltd. Sept. 29, 1954 [Nov. 23, 1953], No. 32452/53. Class 83 (2). [Also in Group XXX] In a method of making radiators, nests y, Fig. 2, of spaced fins having apertures for the radiator tubes x are traversed in front of stacks of tubes in hoppers a from which the lowermost tubes are succesively fed into the apertures through slots g in the fin nests y. The hoppers a are arranged in groups which operate simultaneously on successively fed fin nests to feed tubes to rows of apertures at different levels. The hoppers a are curved at the base and the lowermost tubes rest on stops b which are set at the correct angle to align with the apertures in the fins. Swords c, Fig. 3, actuated by a pneumatic cylinder e through a trolley f push the tubes through. The fins may be assembled in a nest as described in Specification 749,014 and each is initially fed by pawls on bars k actuated by an hydraulic or pneumatic cylinder l to move the nest into position. On the return stroke of the cylinder 1, racks m on the bars k are brought into engagement with pawls n on the fin nest y. Subsequent reciprocation of the racks m through an hydraulic cylinder o causes stepby-step movement of the fin nest during which tubes x are successively fed from the hoppers a. On completion of a row the cylinder l is again actuated to bring the fin nest y into the next position for operation in the next row:

Abstract: 793,072. Gas meters. RADIATION, Ltd. Nov. 13, 1956 [Nov. 15, 1955], No. 32657/55. Class 54. Adjustable means for securing the flag rod 1, Figs. 1 and 2, of a dry-gas meter to its flag arm 6 comprises a bridge member 3 spaced by the flag rod from a surface 4 provided either on the flag arm or a member rigid therewith, and means on the flag rod for preventing it from rotating relatively to the bridge member and for permitting it to perform limited rotation in relation to the surface 4 when the bridge member and surface are relatively slewed. As shown in Fig. 1, the flag rod is clamped by screws 5 between the curved surface 4 on a lug 6a on the flag arm and the bridge member 3 which engages a flat surface 2 on the flag rod; by releasing one screw and tightening the other the bridge member and flag rod are slewed relatively to the flag arm. This arrangement may be modified by providing a hole 8 in the flag arm for the reception of the flag rod which is clamped in position by nuts 7 on the screws 5 urging the bridge member 3 against the flat surface 2 on the flag rod. An alternative form of adjustment consists in mounting a T-shaped member 11, Fig. 3, rigidly on the flag rod 1 and clamping a pin 9 which depends from the flag arm between such member and the bridge member 10. Instead of providing a flat surface on the flag rod 1 or pin 9 to prevent rotation of these members relative to the engaging surface, serrations may be employed to achieve the same effect.

Filed: 1948-12-20
Abstract: 656,709. Ignition systems. ARNOLD, J. C. (Smitsvonk N.V.). Dec. 20, 1948, No. 32893. [Class 7(iv)] [Also in Group XXXVII]' In an electrical ignition system comprising an ignition condenser 5, Fig. 1, at least two spark plugs 4 of the surface-discharge type across which the condenser is either directly charged or discharged, a distributer 1 consisting of a number of circumferentially arranged fixed contacts 2 and a rotatable contact arm 3 co-operating therewith, the distributer connecting the spark plugs successively to the condenser 5 and being the only means for the determination of the moment when the igniting sparks are produced, it is arranged that the active surfaces of a fixed distributer contact 2 and the contact arm 3 extend through arcs which subtend angles at the axis of rotation of the contact arm, the sum of which angles is not greater than 10 degrees. A storage condenser 8, which is permanently connected to a direct-current source, not shown, is also connected through a variable resistance 6 to the contact arm 3 of the spark-jump distributer 1, the arm 3 being also connected to the ignition condenser 5 so that the discharge of the latter takes place through one of the sparking plugs 4 when the arm 3 is near enough to the fixed distributer contact 2 connected to that particular plug. The condenser 8 partially discharges through the plugs since the distributer also acts as a contact breaker. The burning away of the fixed contacts 2 and arm 3 is provided for either by making the contacts 2 or the arm 3 radially adjustable, so that the arm 3 may act as a blower to both cool the fixed contacts and to remove any ionized air from the distributer. In a modification the contact arm 16, Fig. 4, has a roller 17 at its end which rolls over the fixed contacts 15, the latter being earthed through spark plugs 18 and connected to a storage condenser 20 through spark plugs 19. The arm 16 is connected to an ignition condenser 21 so that plugs 19 are fired by the charging current of condenser 21 and plugs 18 fired by the discharge of this condenser. In another modification the roller acts to bridge a continuous contact ring and the fixed contacts; the continuous ring may be replaced by a ring of spaced contacts. The ignition condenser may be charged from a source other than a storage condenser and the system may operate with condenser charging current.

Abstract: 246,121. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). Jan. 17, 1925, [Convention date]. Systems depending on static transformers; regulation, automatic.-In an alternating current system 1 connected with taps 7, 8 on a transformer 3, or other supply means, through reactors 9, 10, a thermionic discharge device varies the relation between the reactances so as to regulate the effective voltage of the transformer. The system 1, Fig. 1, is supplied from one phase of a polyphase system 2 and anodes 17, 18 of a mercury rectifier 15 are connected in series with saturation coils 12, 14 on the respective reactors 9, 10 and with a tertiary winding 6 on the transformer 3. The currents in the coils 12, 14 are controlled by transformer 23 supplied from another phase of the system 2, and a vibrating device 27 responsive to the voltage, of the, circuit 1, so that when the voltage falls the effect of the winding 10 is reduced and the effective voltage of the transformer connection rises, and upon rise of voltage the effect of the winding 9 is reduced with an opposite result. This. is achieved by grids 19, 20 which are connected to the transformer 23 in the low and high voltage positions of the device 27 respectively. In a modification shown in Fig. 3, no moving part is used. The grids 19, 20 are continuously energized from transformers 36, 37, the former of which is reversed so that at no load the potential on the anodes will follow the curve c in Fig. 4, whilst the potential of the grids 19, 20 will follow the respective curves b<1>, a. In series with each transformer 36, 37 is a resister 32 and parallel connected reactor 33 to which are respectively connected current transformers 30, 31 in the load circuit 1, which effect the regulation. The voltage drop across the circuits 32. 33 is vectorially compounded with the voltage of the transformers 36, 37 so as to produce a progressive phase displacement of the potential applied to the grids in: accordance with the value of the load current, that is to say, the curves b<1>, a move towards. each other and eventually reverse their positions. The last condition corresponds to full load in which the coil 12 is energized for the maximum extent and the transformer tappings are giving the maximum effective voltage. Specification 140,285 is referred to. In the Specification as open to inspection under- Sect. 91 (3) (a) the controlling element was referred to as an electron-discharge device. This does not appear in the Specification as accepted.
