Abstract: 1,256,788. Electric battery. ESB Inc. 1 May, 1969 [2 May, 1968], No. 22289/69. Heading H1B. A single cell or multi-cell battery comprises a container which is formed in two portions each including one of two opposite end walls and at least one strap connector is secured in the upper part of the container and after the electrodes are inserted at least two electrodes are connected to the strap before or after the two container portions are sealed. In the multi-cell battery shown in Fig. 1 each container portion is divided into cell compartments 16 by partitions 14, into each of which is placed an electrode stack 18 including alternate positive 20 and negative 22 electrodes. The electrodes are connected by intercell strap connectors 28 which extend through partition 14 and end cell strap connectors 34 each of which has a terminal post 36 or 38 projecting upwards and extending through separate lid 27. Alternatively the end strap connector can extend through an outside wall of the container to provide an external connection. The strap connectors have open ended slots to receive the electrode lugs which are brought into the slots in a horizontal direction, and the straps are preferably in the form of inserts around which the partitions 14 are moulded. Thus the two ends of the intercell connectors 28 may be anchored in recesses or projections 44 on the opposite walls of the two cells, Fig. 5. In the embodiment shown the open slots in the two container portions face each other. Each intercell connector has a positive end 30 connected to the positive electrodes in one cell compartment 16 and a negative end 32 connected to the negative electrodes in the adjacent cell. In a modified arrangement the joint dividing the container into two portions is very close to one side edge of the partitions and can be in a vertical or oblique plane. Thus all the strap connectors are in the larger container portion and the open slots of both face in the same direction. A lid may be formed integrally with the two portions, and it can have one or more openings which give access to the strap connectors for effecting the electrode connections.

In Fig. 3, the leading edge 12 of an aircraft wing, has a windowed conducting strut 132 bridging the U- shaped leading edge profile, the strut 132 carrying a plurality of transformer assemblies 151, each of which comprises a primary winding on an annular core passing through adjacent windows 133. The strut 132 and leading edge profile therefore form secondary windings for the transformers. A further windowed strut 131 carrying spaced transformer assemblies 153, 154 is arranged to cyclically heat successive spaced areas of the wing between the struts 131, 132. Struts 22 extending fore and aft carry transformer assemblies 152 which continuously heat spaced strips of the wing between the cyclically heated areas. Heat insulation may be provided on the inner surfaces of the wing and the transformer cores may be made of spirally wound magnetic strip or from two C-shaped laminated sections. The nose ring of an air intake (Fig. 6, not shown) forms the secondary of an annular transformer assembly contained therein. In Figs. 7 and 8 (not shown) an engine intake has three transformer assemblies energized from a three phase supply. Each core has a helical or single turn secondary whose terminals are connected to part of the intake to be heated. To avoid the necessity for large switchgear to control energization of the transformers, they are constructed as twin core arrangements (Figs. 9 and 10, not shown) each carrying a primary winding. In one arrangement (Fig. 9) a reversing switch enables the primary windings to be energized in bucking and boosting relationship. In the other arrangement (Fig. 10) a switch enables one primary winding which is merely a control winding to be switched on to oppose the magnetization of the other primary power winding. In Fig. 11 (not shown), one limb of the oval core of a transformer is divided into a plurality of sub-limbs carrying primary windings which may be switched to control the magnetization.

In one embodiment the body is in the form of a disc and each finger has a tongue 23 on which is detachably and adjustably mounted the workpiece engaging members 12. The tongue 23 is stabilized by a leaf portion 26 formed by slots 24, 25 that also form the tongue 23. The operating force is applied pneumatically or hydraulically to an annular piston 29 which acts through toggle arms 30 to radially deflect the free ends 17a, 18a, 19a of the fingers and release a workpiece. The fluid pressure is applied by means of a stationary pressure box 33 which extends arcuately of the rotatable chuck sufficiently to ensure that when the chuck comes to rest at least one of a plurality of inlet ports 32 are covered. This embodiment may be modified by providing hydraulically actuated thrust pads in each of the slots 21 to act directly on the free ends of the fingers. In a second embodiment (Fig. 3, not shown) the workpiece holder is adapted to internally grip hollow tubes. The free ends of the fingers (40) are connected to a disc piston (42) by means of a laminar flexible link (45) so that longitudinal movement of the radially inner end of the link causes slight radial movement of the outer end of the link to deflect the fingers and move the workpiece engaging members (38). In a third embodiment (Figs. 4 and 5, not shown) the body (50) is in the form of a tubular housing through which a workpiece extends. Two axially spaced sets of fingers (54) are formed by slots and the free ends of which are deflexted radially by levers (57) which pivot about a fixed fulcrum (59). The levers are pivoted by sliding axially a cam ring (64) by means of pistons (63), (65). The cam ring engages rollers (60) on the ends of the levers (57).-
