A laminated lead accumulator is composed of several to hundreds of unit cells in sheet or cylinder shape, each of which has a shell of enhanced plastics for protection and electric insulation. All the grids, one for each unit cell, are connected together and a shockproof material is between casing and unit cells. Terminals and air holes are on the casing.

A fluid dispensing system for delivering sterile preservative free solution is disclosed. The system uses double self-sealing valves mounted in series inside a tip compartment which fits on the outlet of a multiple dosage squeeze container to prevent undesirable retrograde flow of the dispensed liquid back into the bottle during the decompression cycle. The valves used are positive acting, normall...

Rigid mould for moulding rubber tyres, constituted by a core 3 for defining the inner shape of the tyre, lateral portions 2 and a ring 1 of sectors. So as to be able to close such a mould, all the parts are designed to slide over each other during the final phase of their closing movement.

A vial connector has a circular array of detents that snap-engage behind the head of a vial to prevent its withdrawal. In a unitary injection moulding, the detents could not lock completely or the product could not be removed from the mould. Therefore the connector employs independently displaceable detent elements (40), with independent resilient urging means (42).
