Patent CH-497371-A (CH)
Title: Protection of carboxyl gps. in penicillin and cephalosporin synthesis
Inventor: PROF WOODWARD ROBERT BURNS DR
IPC: C07F9/53
Filed: 1965-12-09
Abstract: Temporary protection of COOH groups by conversion into -COOCH2CCl3 groups, the COOH group subsequently being released by treating with chemical reducing agents (e.g. nascent hydrogen, alkali or alkaline earth metals in liquid NH3, or strongly reductive metal salts (e.g. CrII cpds.). Temporary protection of COOH groups in preparative chemistry and during degradation reactions. The 2, 2, 2-trichloroethyl protecting group is readily, but specifically removable by treatment with chemical reducing agents, but is resistant and inert to a wide variety of other reaction conditions. Reactions on the ester group itself (e.g. re-esterification etc. of the COOCH2CCl3 group) can, however, be carried out.

Title: Self organisation of base station frequencies in a wireless communication system
Inventor: GIBBS JONATHAN ALASTAIR
IPC: H04W16/10
Filed: 2001-04-18
Abstract: A self-organising wireless communication system (10) includes a plurality of wireless serving communication units (24-30) serving a plurality of mobile stations (12-16) with a limited communication resource (18-22). At least one wireless serving communication unit (24-30) includes a transmitter transmitting a wireless transmission message (190) including at least a yoohoo message portion (198). The yoohoo message portion (198) identifies whether transmissions from other wireless serving communication units can be received by the at least one wireless serving communication unit (24-30). This enables several BTSs or repeaters to share simultaneously a single frequency and to indicate to their respective fleets of MS's which frequency they are currently permitted to use and need to monitor for their transmissions. This is achieved partly through the concept of a 'map' of other transmissions to allow access and coordination. It also allows collisions to be detected and resolved when they are likely to occur.

Title: Timer-based traffic measurement system and method for nominal bit rate(NBR)service
Inventor: RUUTU JUSSI
IPC: H04L12/56
Filed: 1999-03-24
Abstract: A system and method for controlling cell transmission from a network source unit to network destination units across a network connection is provided. A timer is initiated upon transmission of a cell from the network source unit. A timer output value, provided at the timer output, is adjusted to reflect time lapse measured from the time of initiation of the timer. The timer output value is compared to an expected cell time interval upon transmission of a subsequent cell, to establish a rate variation indicator. The rate variation indicator generally indicates whether the cell transmission rate is increasing or decreasing at a particular time. A cell priority value, derived from the rate variation indicator, is loaded into the subsequent cell for use by the network connection.
