Abstract: A portable electric lamp including a body 1 mounting a lens 2, a lens holder 3, a reflector 5, and a bulb holder 6 is provided with a translucent diffuser sleeve 7 which has slots 8 which extend lengthwise thereof. The diffuser sleeve is coaxial with and surrounds the bulb holder and is associated with drive means 10-13 operable to effect axial movement of the diffuser sleeve relative to the bulb holder between a retracted position at which a bulb held in the bulb holder is arranged to direct a spot beam through the lens and a forward position at which light from the bulb is diffused by passage through the diffuser sleeve.

Abstract: An electric storage battery having a plurality of cell compartments separated from each other by wall means formed of thermoplastic plastics material, each cell compartment containing a plurality of plates electrically connected together, the plates of one cell compartment being electrically connected to the plates in an adjacent cell compartment by an intercell connecting rod which provides a direct connection between adjacent cells through the wall means, the rod having been embedded in position in the wall means by deformation of the wall means when the thermoplastic plastics material was softened by heat.
