Title: Bandwidth allocation on DPNSS networks
Inventor: BENISTON GRAHAM
IPC: H04Q3/66
Filed: 1993-03-29
Abstract: A DPNSS (Digital Private Network Signalling System) link between two switching nodes comprises a number of trunk lines. These are grouped into trunk groups. Trunk Access Class (TAC) is a code used to differentiate different classes of traffic. In the switching nodes, a table exists which defines to which trunk groups access is allowed or barred by TAC. This means that bandwidth (or trunks) in the DPNSS link can be allocated by class of traffic. The present application relates to the dynamic allocation of bandwidth using the above technique. The grouping of trunks into trunk groups and the table which allows or bars access to trunk groups by TAC may be altered from time to time in the switching nodes at each end of the link by management command, to vary the allocation of bandwidth between classes of traffic in the DPNSS link. <IMAGE>

Patent GB-2292905-A (GB)
Title: Blow moulded plastics bottles
Inventor: BRITTON CHARLES JONATHAN
IPC: B29C49/48
Filed: 1995-08-31
Abstract: Plastics bottles (1) of oblong cross-section are blown in mould cavities (11) defined in blow mould halves (9, 10) such that the split line (12) of the cavities extends along wider sides of the formed bottles. The arrangement enables more bottles to be blown in a moulding operation in a given size of mould than would be possible were bottles of similar cross-section and size to be formed in the mould with the split line along the narrower sides of the formed bottles. Because of the higher production rate bottles may be produced from more expensive plastics materials, such as p.e.t., at prices competitive with glass bottles of similar sizes and shapes. Parisons may be formed with screw-threaded necks before stretch blow moulding to the final shapes of the bottles. <IMAGE>

Title: Adapting printer drivers
Inventor: STOKES DEVERL N
IPC: G06F3/12
Filed: 1996-08-19
Abstract: The present invention allows for field changes of the function of a print driver based on the application requesting print driver services. First, a utility is activated. Using the utility, the application is selected and a flag is set that indicates the problem function. The flag and information about the associated application are stored in a data structure. Finally, the data structure is stored in a storage device (21, 18). When the application (15) requests services of the printer driver (22), all the data structures are scanned (202) looking for an entry for the requesting application. If an entry is found, then the function flag is used to direct a change (206) in the function of the printer driver (22). If an entry is not found, then a permanent list is searched (204) for an entry of the application (15). Again, if an entry is found in the permanent list it is used to direct a change (206) in the function of the printer driver (22).
Patent GB-2304522-A (GB)
Title: Injection of identifying chip
Inventor: WEBBER RICHARD SYDNEY
IPC: A01K11/00
Filed: 1996-08-23
Abstract: An identifying chip is installed reliably, e.g. in the base of an animal's ear, by inserting a tubular needle containing the chip to a depth less than the length of the chip, e.g. about half the length. Operating a plunger then pushes the chip out and serves to push the chip forward between the cartilage of the ear and the skin nearer the base of the ear. This action, therefore, allows the use of the rounded end of the chip to find its location without fear of the needle going through the ear. Even young animals can be tagged in this way. Thereafter the animals can be easily monitored and data can be logged on a computer.
