Filed: 1992-07-15
Abstract: A telecommunication system includes a number of radio base stations 5 connected to a telephone network 1, the base stations forming a link to the network for a number of cordless telephones 7. Each base station 5 determines which, within a number of predetermined signal strength bands, the signal strength of a signal produced by a cordless telephone 7 and received by the base station 5 lies. If the received signal strength is in the highest signal hand, the base station 5 sets up a link between the cordless telephone 7 and the telephone network 1. If the received signal strength lies in a lower band, the base station 5 stores an indication of the signal, and scans through the communication channels available between the base station 5 and the cordless telephones 7 to determine whether a new incoming signal lies in the highest signal band, or whether by increasing the band rank of a stored signal, the highest signal band is reached. <IMAGE>

Title: Digitals open-edi scenarios automation process
Inventor: FOX CHARLES MICHAEL
IPC: G06Q10/00
Filed: 1992-09-26
Abstract: EDI (Electronic Data Interchange) systems deal with messages relating to business transactions. Message-based (batch) EDI deals with individual messages. Transaction-based EDI (I-EDI, interactive EDI) deals with transactions as wholes, messages having headers identifying their transactions. Transaction types are defined by scenarios, and individual transactions by instances of the transaction scenarios. A general-purpose transaction-based EDI system requires preprocessing means (50) for passing message-based system messages through to a message-based EDI subsystem (59). In the present system, the preprocessing means attempt (56, 57), for non-transaction messages (ie messages without transaction headers), to match them with the scenarios and instances, to thereby identify the transactions to which those messages relate. <IMAGE>

Title: Barium ferrite thin film magnetic recording medium
Inventor: AHLERT RICHARD HENRY
IPC: C23C14/08
Filed: 1994-05-25
Abstract: A high-density recording media comprising longitudinally oriented polycrystalline barium ferrite exhibits large coercivity, corrosion resistance, high hardness and durability. Films are prepared by on-axis sputtering at ambient temperatures from stoichiometric targets followed by a post-deposition anneal at approximately 850 DEG C to induce crystallization. Crystallization yields a magnetic film with large in-plane remanence and a fine scale texturing that greatly improves the tribological performance of barium ferrite disks. Exceptional durability can be achieved on disks without overcoats. Grain sizes as small as 200 ANGSTROM  are produced by doping with small amounts of Cr2O3 or other additives. Coercivities greater than 4000 Oe are achieved even in small grain films.

Title: Laser nitriding
Inventor: BAKER THOMAS NEVILLE
IPC: C23C8/24
Filed: 1994-08-30
Abstract: A method of increasing the surface hardness of a metal comprises locally melting the surface of the metal by laser excitation under a stream of nitrogen and controlling the availability of nitrogen within the field wherein the nitrogen stream is diluted with an inert gas. This method of laser nitriding results in substantial hardening of the treated metal but eliminates surface defects such as cracks or pores, which occur in prior art techniques. This controlling is achieved by dilution of the nitrogen gas stream with an inert gas, adjusting the flow rate or laser traverse speed. Rotation of the laser beam also eliminates surface defects.
