Title: Improvements relating to can seaming machines
Inventor: PERKINS CHARLES WILLIAM
IPC: B21D51/32
Filed: 1951-05-01
Abstract: 702,551. Seaming sheet metal. BLISS CO., E. W. Jan. 17, 1952 [May 1, 1951], No. 10174/51. Class 83 (4) In apparatus for feeding can lids from the bottom of a stack to a seaming chuck an oscillating transfer. arm beneath the stack carries the lowermost lid to a position below the seaming zone and the lid is raised by upward movement of a can body to the seaming chuck or in the absence of a can body the lid is returned by the transfer arm. A stack of lids (not shown) is supported between four vertical posts 8, Fig. 4, mounted on a base plate 9 attached to a can seaming machine. The lowermost lid of the stack rests on an oscillating transfer arm 10, Fig. 6, mounted on a pivot 11 and having a recess 13 to engage the lid and is carried by the arm 10 to a position beneath the seaming chuck. The lid is then raised by the upward movement of a can body (not shown) fed to position by a conveyer and raised through the aperture 12 on the arm, a throat 14 of the aperture then permitting the arm to return without fouling the can body. During the period in which the transfer arm is beneath the seaming chuck the stack of lids is supported by a pair of oppositely disposed knife separators 30 slidable in grooves 30a and automatically moved inwards to support the stack. These separators 30 hold the stack clear of the lid on the arm 10 so that it may be returned beneath the stack if not removed by a can body. Oscillation of the arm 10 about the pivot 11 is obtained from a crank 19 driven by a machine drive shaft 4 and connected to the arm through a link 17 having a slot 28 in which a pin 29 on the arm 10 is engaged. The drive incorporates a slipping clutch to prevent damage in the event of a lid being out of place. Movement of the knife separators 30 is obtained from a cam 37 on the link 17 which engages a projection 36 on a link 35 coupled through a link 34 to a pair of interconnected bell cranks 32 pivoted to the separators 30. A spring 40 normally holds the separators 30 in the withdrawn position. The separators are locked in position to retain the stack after the cam 37 has passed the projection 36 by a spring loaded latch 57 having a face 38 which engages a projection 39 on the link 34. As the arm 10 returns beneath the stack a projection 42 on the cam 37 engages the latch 57 and releases the link 34 so that the separators 30 retract and release the stack. In a modification the apparatus is adapted for handling different sizes of can and lid by the insertion of detachable members on the arm 10 and base plate 9 to provide recesses 13 of required dimensions and repositioned tapped holes for screwing in the vertical posts 8 to suit the lid dimensions.

Title: Improvements in methods of, and means for, reducing the lagging current on alternating current systems supplying induction motors and the like
IPC: H02M5/12
Filed: 1919-04-24
Abstract: 152,703. Barry, H. A. L. April 24, 1919. Systems depending on the use of static transformers; dynamos and motors combined for transmitting power.-Relates to a method of improving the power factor of alternating-current apparatus working under load, such as induction motors, or transformers. The method consists in impressing upon the working apparatus a current out of phase with the mains, the difference of phase being such that the lagging current is compensated, and the impressed current being taken from the station distinct from the power current. Fig. 3 shows one arrangement for carrying the invention into effect. A working three-phase transformer R receives energy along mains A, B, C. According to the invention, tappings a<1>, b<1>, c<1> on a stepup transformer T feed the primaries of a boosting- transformer V the secondaries of which are respectively in series with the secondaries of the working transformer R. In the example shown, the phase difference between the working and the electromotive force impressed by the boosting transformer is 120 degrees. Suitable positions of the tappings a<1>, b<1>, c<1>, may be chosen to give any required phase difference. In another arrangement, the secondaries of the boosting-transformer supply additional windings upon the working transformer, the out-of-phase flux produced by the additional windings affording the required compensation. In a further arrangement, the boosting-transformer is dispensed with and the phase-compensating windings on the working transformer are directly connected to the tappings of the transformer at the station. When the invention is applied to induction motors, phase-compensating windings are placed either on the rotor or stator, and the impressed current is of low frequency relatively to the working current. Alternatively to the use of static transformers at the station, other apparatus such as generators or motor-generators may be used for supplying the compensating-current.

Title: A control system including a regulating member operating in opposite directions
IPC: G05D3/14
Filed: 1956-04-06
Abstract: 816,297. Switching systems for reversing machines; transmitting mechanical power. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. April 6, 1956 [April 6, 1955], No. 10573/56. Class 38 (4). [Also in Group XXIV] A circuit for effecting the rapid braking of a reversible machine by operating the reverse clutch or contactor, consists of two valves VI, V2, controlling the current of two magnetic clutches or contactors K1, K2. Closing switch S1 drives grid G1 less negative, causing V1 to conduct and operate K1. On opening S1, V1 cuts off the supply from K1 and the collapsing field of the latter induces a voltage pulse which appears across a series combination comprising a condenser C1 and resistor R1. An adjustable tap on R1 applies part of this voltage to G2, causing V2 to conduct and operate K2. As the induced voltage across K1 falls, G2 again becomes negative, thus reducing the current through V2, K2 to zero. To increase the amplitude of the voltage pulse, a capacitor C3 may be connected across part of R 1; conversely, to limit the amplitude of the voltage pulse at G2, a rectifier T2 may be connected between G2 and the negative end of R2. A similar sequence follows for V2 when S2 is closed. Resistors R3, R4 limit the current drawn from the biasing source when S1, S2 are closed. Valves V1, V2 may be replaced by transistors by suitable circuit modifications.

[Also in Groups XXI and XXXIII] In an anti-aircraft weapon system comprising apparatus for locating an enemy missile, a ground control post, a battery of ground-to-air missiles and means for initially guiding said missiles towards the enemy missile in accordance with the position data obtained, certain components of the locating apparatus are mounted on an aerial buoy at a substantial fixed height above the ground control post so as to increase the detection range of lowflying missiles. When the location system utilizes the reception of ratio on infra-red waves emitted or reflected by the target missile, the receiver is located on the buoy and is connected to the control post by a wire or radio link; in reflection type systems, e.g. radar, the transmitter may be located on the buoy or it may be located at the control post and directed upwards to a reflector mounted on the buoy. The aerial buoy may comprise a captive buoy having powered means for transverse stabilization as disclosed in Specification 897,756. The defence missiles may be wholly guided by a " beam-rider " or command system, or alternatively the final guidance may be effected by an active homing system utilizing the reflection by the target of radio, infra-red or light waves. Figs. 4 and 5 (not shown), illustrate solid and liquid fuel missiles (see Groups XXI and XXXIII) suitable for short and long-range operation respectively.

Abstract: 1428363 Fluid filter with flowmeter SPERRY RAND LTD 26 Feb 1973 [8 March 1972] 10815/72 Headings B1D and BIT A flow meter 26 normally indicates the fluid flow through filter element 1. but if the element is removed from the casing 2 and not replaced the flowmeter will thereafter indicate zero flow. In Fig. 2 flowmeter 26 is a spinner rotated by flow past vanes 28, but removing element I opens passages 25 and fluid then by-passes the vanes and passes down through apertures 34 to urge the spinner down onto nut 22 and hold it still. In Fig. 3 (not shown) an arrester (31) normally held off the spinner by legs (32) engaging element 1 descends to hold the spinner if the element is missing. Fig. 2 shows an integral gear pump 15 and filter unit. Apertures 19 and 20 may be connceted by a by-pass valve to prevent pump damage and a non-return valve is shown at 30. This unit may continuously filter hydraulic circuit oil, drawing it from and returning it to the reservoir without passing through the main circuit. In Fig. 1 (not shown) flow from the outlet end of a filter element normally urges a valve-like member (10) away from the element end against a spring (11), and the member carries an indicator (9). At zero flow, for example when the element is clogged, the member (10) engages the element and the indicator is visible through a window. If the element is absent the member (10) assumes a similar position and the indicator is again visible. The invention is applicable to pneumatic circuits.
