Title: Battery charging and discharging system
IPC: H02J7/00
Filed: 1974-07-22
Abstract: 1462916 Systems for charging and discharging batteries TADIRAN ISRAEL ELECTRONICS INDUSTRIES Ltd 22 July 1974 [3 Aug 1973] 32408/74 Heading H2H A system for charging and discharging a battery B comprises a circuit for charging the battery from a mains supply, a switching circuit responsive to failure of the mains supply to discharge the battery through a lighting load L1 and a control circuit which stops the discharge of the battery when the battery voltage falls to a predetermined level. When the mains supply is present, a relay RL1 is energized so that its contacts RL1-C engage contacts 10, 12 thereby enabling the energization of a relay RL2 via movable contact PC1 and fixed contact 62 of a three position switch PSW which is set in its "automatic" position and a series resistor R3. The contact RL2-C of the relay RL2 engages a contact 24 so that the battery B is charged by a bridge rectifier BR. On failure of the mains supply the relay RL1 is de-energized so that the contacts RL1-C engage contacts 14, 16 but the relay RL2 remains energized by the battery. The load is therefore energized by the battery until the battery voltage falls to a level which is insufficient to maintain the contact RL2-C in its actuated position. This contact therefore engages a contact 22 to disconnect the battery from the load. In another position of the switch PSW in which contacts PC1, PC2 engage contacts 50, 60 respectively, "non-automatic" operation of the system occurs such that on failure the battery is not automatically connected to the load until the switch has been momentarily actuated to a third unstable position from which it returns to the "automatic" position.

As shown a spray device generally indicated at 1 is mounted beside and above a conveyor 2. The traversing device comprises a portal structure 3 on opposite sides of the conveyor and interconnected by crossbeams 5 and 5'. A guide beam 8, along which the spray head travels is connected to the lower cross-beam by bearing 6 and swivel shaft 7. The guide beam carries a pair of horizontal, parallel hardened rods 18 and 19 along which the mixing head support 21 is movable by means of ball bushings. The mixing-head support is driven by a traversing motor 22 mounted on beam 8, via a multiple sprocket which drives a three-fold chain. The speed of the :motor is adjustable. The guide beam is swivelled by a pair of pneumatic cylinders 9 and 10. These cylinders are pivoted at 11 to guide beam 8 and at 12 to support 13. The angle between the cylinders is adjustable by a worm driven by rod 15. The lower beam is adjustable relative to the upper beam by worm transmission 16 and rod 17. The swivelling of the beam is controlled at the top of the mixing head 21 by stops which acuate adjustable end switches 46 on opposite sides of beam 8. These end switches actuate cylinders 9 and 10 by impulse-operated valves not shown. To prevent material spraying beyond lateral edges of the web, a pair of airscreen boxes 37 are disposed on opposite sides of the web. From these boxes air jets are directed to the centre of the web which consequently gives at the outer edges of the web a slightly thicker coating. The boxes 37 and a trough 38 for testing feed supply of the sprayer are supported on a carrier structure movable on wheels 38. The swiveling movement may also be controlled by photocells, approach switches or rods. Different web widths may be used.
