The terminals 36 of an electricity meter, time switch, or other apparatus are contained within cavities 35 formed between two inter-fitting insulation-members 33, 34 which are engaged together in a direction parallel to that of the axes of the terminals, those parts of the inner member lying outside the apparatus housing being surrounded on all sides by the outer member. As described, the electrical part of a meter is placed inside the base portion 2 of its housing with the winding ends 31 projecting through a slot adjacent a reinforcing web 40. An inner insulating member 33 is then introduced into the slot until it abuts shoulders 41, the winding ends 31 passing through apertures 42 made by knocking out thin walls left during manufacture. An outer insulating member 34 containing jacket terminals 36 is slid over the inner member 33 and is secured in position from inside the housing by screws 4 engaging a footplate 5 which is fixed to it by rivets 39. The winding ends 31 are held, together with external lead wires 32, in the terminals 36 by screws 37 which are fitted with pressure plates 38. The rivets 39 may be provided with internal threads to enable a terminal cover 7 to be fixed by screws, Fig. 1 (not shown). The cover 3 of the meter housing may be similarly secured, using a lead sealable screw, with a gasket 43 between the cover and a limb of the web 40. It is stated that the shoulders 41 function as a labyrinthine seal preventing the entry of dust. Socket terminals may be used instead of the jacket terminals 36.

A circulator for electromagnetic wave energy for use in communications in which waves applied at port a are transmitted to port b, application at port b leads to port c and application at c to d and at d to a is designed for use in the optical wavebands so that lasers may be used. As shown linearly polarized light from source 23 has its plane of polarization parallel to the optic axis of a Glan-Foucault prism 11 so that it passes therethrough to a Faraday rotator 14-which rotates the plane of polarization through 45‹ in a clockwise sense viewed from prism 11 regardless of the direction of propagation along axis 13. The beam then enters a second Glan-Foucault prism 12, which is orientated 45‹ with respect to prism 11, so that the beam passes therethrough to port b and transducer 24. If a beam having a plane of polarization parallel to the optic axis of prism 12 is applied at port b it passes through prism 12 is rotated 45‹ by rotator 14 and has now a plane of polarization rotated 90‹ with respect to that of the beam from source 23 and the direction of the optic axis of prism 11 and so is internally reflected in prism 16 where it abuts the air gap 17 separating prism 16 from prism 15 and emerges at c to transducer 25. Similarly a beam introduced at port c with a polarization normal to the optical axis of prism 11 is internally reflected to pass through rotator 14 and thus, having a plane of polarization normal to the optic axis of prism 12 is internally reflected to emerge at port d and transducer 26. Similarly a beam may pass from d to a. If only three ports are required reflection may be introduced at one port e.g. the prism face associated with port c may be silvered. A four port circulator-amplifier may be provided, Fig. 5 (not shown), by inserting a laser (50) between the rotator (53) and either prism (51) or prism (52).
