A casing for a portable communication device having an operating face comprising a fragile input region providing recesses for operation of respective user input elements and a protection arrangement protruding beyond the fragile input region having an external profile that provides a plurality of contact points defining a contact plane such that when placed face downwards on a generally planar surface, the fragile region is spaced therefrom and impulses received on contact between the generally...

The invention relates to casings for portable communication devices. The casing is reusable with engines having different processing capabilities.

The invention relates to casing for portable communication devices and light guides for such devices. The casing (2) has a light guide for over-laying a display located in the display region (4) to deliver front lighting to the display and extending across the input region (5), the light guide providing a recess in the input region for operation of a key of the key arrangement.

The invention relates to portable communication devices and in particular to the casings of such devices. The casing has an operating face providing a key arrangement for operating face provides recesses in the input region for operation of the keys.

A casing, particularly for roll film cartridges, includes a hollow housing having a chamber for closely receiving a film cartridge and a channel which communicates with the chamber. The channel is operative for receiving a length of roll film which extends out of the cartridge when the latter is inserted into the chamber. The channel extends tangentially to the chamber and has at least one flat inner surface along which the length of roll film can extend to be held in flat condition.

A casing for an electrical apparatus having a front wall and a back wall, an electrical plug on said back wall, said casing having a base, a jacket in which said apparatus is mounted, said jacket being detachably fixed to said base, a passage in said base, a set of cables through said passage, a plug socket fixed to said cables, said back wall, said jacket and said base forming a water sealed room, said plug and said plug socket being within said room when said jacket is fixed to said base.

An electromagnetic radiation barrier (30) for a casing, particularly for a personal computer, is formed by a connecting member having a generally U-shape with one arm (31) of the connecting member being fixed between an upturned edge section (12) of an upper casing member and another part of the upper casing member. The U-shaped member is made of a resilient metal so that upon insertion of an upper portion (21) of a lower casing member (20) into the cavity (33) defined between the arms of the co...

A casing tube formed from plastic and a casing shoe formed from metal are provided for drilling in layers of earth or rock. The casing shoe is locked to the casing tube by threads, grooves or flanges provided on a reduced diameter portion of the casing shoe. A tube-formed extension is provided in the casing shoe for protecting the casing tube from damage during a drilling operation.

A casing element for excavation casing wherein all of the elements thereof are interconnected by spot welding whereby the usual warping and twisting of similar casing elements due to conventional welding practices is eliminated. The sheets and spacer bars of the casing element are secured together and to the frame of the casing elements solely by spaced spot welds which do not thermally stress the casing elements sufficiently to effect warping and twisting thereof from a planar state.
