Abstract: 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.

Abstract: A mobile device operable with keys 14 having characters 16 engraved onto the surface of the keys. To provide back illumination, visual traces of the characters are provided by a plurality of holes 18 made to the keys to provide spot light outlets adapted to collectively define the traces. The holes can be drilled and the key caps can be made of steel or other metals. The grooves 16 can be closed by a translucent material such as resin to block the ingress of dirt into the holes 18.

Abstract: A mobile telephone (1) comprising keys (5 to 10, rows 11 to 14) hinged from the end opposite to a display (2) so as to allow positioning of the keys partly over the display (2) to place soft keys (5,7) next to respective legends (3,4) shown on the display (2).

Abstract: The invention relates to a casing for a portable communication device. The casing has an operating face carrying user input elements and a display, and rails are provided along an intersection between adjacent housing elements to obscure the edges of the housing elements, on the exterior of the assembled housing.

Abstract: The invention relates to a method of customisation of portable communication devices. A plurality of casing elements capable of individual formation are designated. The character of these elements is selectable by a commissioning party. The characters selected are communicated to a production facility for realisation of the customised casing.

Abstract: The invention relates to personal communications devices and housings for such devices. The casing includes a front face that needs protection and is supported by a substrate that is gripped between an overlaying any underlaying part to secure it in position.

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

Abstract: The invention relates to a casing for a portable communication device. The casing has an opening face carrying user input elements and a display, and rails are located against movement relative to a spacing element to strengthen the casing against flexing.

Abstract: 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 planar surface and the operating face are substantially dissipated away fom the fragile region.

Abstract: The invention relates to the customisation of portable communication devices. The casing is formed from a number of elements capable of individual formation. The materials of the individual elements are selected from a preselected set by a commissioning party. The selected elements are utilised in manufacturing a casing.

Abstract: A portable telephone assembly comprising first and second portions arranged to be mutually detachably interconnectable is disclosed. The second portion is arranged to be removably attachable to a user. The first portion comprises a body portion and an extendible portion movable between a relatively extended configuration and a relatively contracted configuration. The extendible portion is biased towards the relatively extended configuration, such that when the first portion is detached from the second portion, the extendible portion is urged towards the relatively extended configuration.

Abstract: A portable telephone assembly comprising first and second portions is disclosed. The first portion comprises a primary power source, is independently operable as a portable telephone and is arranged to be detachably connectable to the second portion. The second portion is arranged to be removably attachable to a user and comprises an auxiliary power source operable to supplement the primary power source when the first and second portions are connected.

Abstract: A communication apparatus having a first portion, a second portion and an extendible antenna is disclosed. The second portion is movable relative to the first portion. Such movement causes a corresponding movement of the antenna.

Abstract: An egg breaking knife used in an egg breaking device which increases the yield of the egg breaking device. The upper edge of the egg breaking knife is in a “V” shape. The “V” shape creates a lower drainage point to eliminate any “damming” of egg shell contents which may occur in the egg shell halves. The knife edge of the egg breaking knife of the present invention may also include a vertical slot or opening, preferably at the vertex or intersection point of the “V” shape, which assists in preventing “damming” of egg contents and enhances the drainage of egg contents from the egg shell halves. The lower edge of the egg breaking knife of the present invention may include a drip point, preferably located below the vertical slot, which serves to collect all egg content drippage at a single location, to ensure that a minimal amount of egg content drippage remain adhered to the egg breaking knife during egg content dumping.

Abstract: An improved flood lighting fixture for a horizontally mounted HID lamp is disclosed. Relamping is accomplished by removing an access cover to expose an access opening, pivoting a reflector to a relamping position, exchanging the lamp through the access opening, pivoting the reflector back to its normal position and replacing the access cover.

Abstract: A mining machine of the type comprising a body, a driven cutter mounted on the body, and an air-cleaning system comprising ducting for conducting dust-laden air, a scrubber for applying liquid to the dust-laden air, and a demister for thereafter removing moisture from the air. The demister comprises a moisture separating station having a flow inlet, a flow outlet located rearwardly of the flow inlet, and moisture separating louvers forming air channels which receive air flow from the inlet and causing moisture in the air flow to separate-out and gravitate toward a lower collecting surface to be conducted rearwardly. A moisture accumulating section is located adjacent a rearward end of the collecting surface to receive the rearwardly conducted moisture. The accumulating section includes a floor, an end wall, a top wall, and a forwardly facing entrance for admitting the moisture.
