Title: Treatment of eczema with N-acyl-L-phenylalanine esters
Inventor: SCHALLREUTER-WOOD KARIN UTA
IPC: A61K31/216
Filed: 1995-03-06
Abstract: Non-polar, hydrolysable, N-acyl-L-phenylalanine esters are applied to the skin to treat eczema, particularly N-acetyl-L-phenylalanine ethyl ester (NALPA ester). This compound undergoes hydrolysis in the skin to yield L-phenylalanine, ethanol and acetic acid thus minimising the risk of side effects.

Patent GB-2287611-A (GB)
Title: Multimedia communications systems
Inventor: YUNOKI HIDEO
IPC: H04Q3/00
Filed: 1995-03-17
Abstract: In setting up a multimedia communication between terminals A, B involving a plurality of calls through different media, generating means, eg. at a service switching point 22, represent a call by generating "call objects" formed by connection points (CPs) connecting legs which correspond to the communications resources (physical or logical) assigned to a call request. CPs and legs are defined for each type of medium involved in the multimedia communication, and each CP is defined as a parent or child. A connection point generated at the time of a first call request is denoted as a parent CP; connection points subsequently generated in the same multimedia communication are denoted as child CPs. A multimedia communication involving a plurality of calls each requiring a different medium can be processed as a single "call object" by communications control means, eg. at a service control point 21, whereby a call processing load can be reduced. The processing is based on the relationship between connection points belonging to the same "call object". A process of charging an account on a multimedia call can be simplified by recording call history information for each connection point. <IMAGE>
Patent GB-2299798-A (GB)
Title: A device for controlling the lateral movement of the boom of a sailing boat.
Inventor: SCOTT DONALD ALAN
IPC: B63H9/10
Filed: 1995-04-13
Abstract: The boom 2 of a sailing boat is fitted with a clamping device 6 through which is passed a rope 7 fixed at both ends. When the rope 7 is clamped by the clamping device 6 the boom 2 is prevented from swinging laterally. The clamping force is increased by passing rope 7 a number of times round a non-rotating drum 19 forming part of the device. The clamping force is generated by passing rope 7 through a clamping element 20 external to drum 19 which can be drawn towards the axis of drum 19 by a mechanism which includes a toggle linkage which reaches top dead centre in the clamping position. The linkage can be operated by a remote control element 9 in such a way that pulling the remote control element causes boom 2 to be locked and releasing it allows the boom to swing freely. The device can be attached to a track formed in the underside of boom 2 by a split mounting 15 which can be inserted anywhere along the length of the track without disturbing other fittings.

Patent GB-2311392-A (GB)
Title: Data structure
Inventor: GREEN RUSSELL J
IPC: G06F17/30
Filed: 1996-03-22
Abstract: During operation of a computer system, index records and data records of a data structure are organized in a hierarchical manner, with index records being at a higher level of the hierarchy than the data records referenced by the index records. While the data structure is manipulated, the data records are stored in a random access memory. Modifications made to the data structure are chronologically written to a disk storage in a bottom-first/top-last order of the hierarchy for persistent storage as a database. A back-up copy of the database is made by storing the data and index records of the database in a top-first/bottom-last order on a sequentially readable media. A temporal and spatial view of a portion of the database can be obtained by accessing the index records and the data records of the database or the back-up media in the top-first/bottom last order.

IPC: H04B7/185
Filed: 1997-11-06
Abstract: A communication system comprises a constellation of satellites, a multi-channel unit 22 having a plurality of co-located transceivers 40, 42, 44 and 46 and a plurality of user handsets 54. When the transceivers are not in use with a call in progress they are set to monitor a plurality of spot beams transmitted from the satellites for ring alert data contained within the broadcasted channels. Ring alert data from various channels may be sampled to provide an optimum group of channels based on received signal strength, this optimum group is then monitored. The number of spot beams transmitted from the satellite may be controlled in inverse proportion to the number of channels being monitored by the multi-channel unit. The number of channels being monitored may be determined by the candidate handoff lists transmitted to the multi-channel unit.
