Abstract: A method and system for selectively fully displaying additional content in a browser window, without requiring scrolling in more than one direction, based on an available display area. For example, additional advertising content is thus selectively displayed in an otherwise unused area of the browsing window to the right of a primary content of a Web page. The size of the available display area is automatically detected, and a determination is automatically made as to whether the additional content and primary content can both be fully displayed in the available display area under the scrolling constraint. If so, both the additional content and the primary content are displayed. Otherwise, only the primary content is displayed. The additional content is downloaded only when it can thus be included within the display area.

Abstract: A serial interface for interfacing communications traffic, e.g. frame based voice traffic, with a cell or packet based communications network, the interface comprises; a transmit unit and a receive unit, the units being coupled via a first serial line and one or more further serial lines. The transmit unit has packetising means for packing the communications traffic into micro-packets, each having a header portion containing control information and a payload portion. The payloads and control information are transmitted in parallel respectively over the first and further serial lines to the receive unit The receive unit has means for receiving the transmitted payloads and for relating the corresponding control information thereto.

Abstract: In a mineral mining machine of the shearer drum cutter loader type, a system for supplying water at the required pressures includes an intensifier to which in use mine supply water is fed, the pressure being enhanced in the high pressure chambers and the high pressure water being fed to jets on the end of the cutting drum. Water exhausting from the low pressure chambers is fed to the dust and frictional sparking suppression sprays arrayed along the surface of the cutting drum. The method of the invention consists of generating in a simple and effective manner the requisite water pressures utilizing an existing main supply.

Abstract: Lenses (10,11) , e.g. for a camera for a video conferencing system, have divergent optical axes and focus real images via prisms (20,21,22,23) on to a focal plane f. A prism (20) in one path introduces an additional reflection to invert the image while that (22) in the other path causes lateral inversion, so that the two images do not suffer either type of inversion relative to one another. The final reflecting surfaces 211,231 abut in the plane f so that the real images are closely juxtaposed.

Abstract: The machine comprises a rotatable cutting head and a high pressure water nozzle. The nozzle directs a jet of high pressure (up to 2,100 kg/cm.sup.2) water at the rock adjacent the cutting head. The jet of water provides an auxiliary cutting and breaking action, thus easing the load on the head. The water jet also suppresses dust formation.
