Title: Preparation of morphinan derivatives comprising N-demethylation, reductive amination and O-demethylation steps
Inventor: RD ANNE METTE NYG
IPC: C07D489/08
Filed: 2006-05-25
Abstract: A process for the preparation of a compound of formula (I) wherein R is a cyclopropyl, cyclobutyl or vinyl group, X is O or an optionally linked diC1-4alkoxy group comprises N-demethylating a compound of formula (II) by reaction with   a  -chloroethylchloroformate to form a compound of formula (III). The residue CH2-R shown in formula (I) is then introduced by reacting the compound of formula (III) with an aldehyde RCHO to form an intermediate with an iminium ion double which is reduced to form a compound of formula (IV), i.e. CH2-R is introduced by reductive amination.. The compound of formula (IV) is then reacted with BBr3 or other reagents capable of demethylating an aryl methyl ether to form a compound of formula (I). Preferably R is cyclopropyl and X is O, the compound of formula (I) then being naltrexone. N-Demethylation may be carried out in an aprotic solvent, e.g. 1,2-dichloroethane or acetonitrile and the reductive amination may be carried out in tetrahydrofuran, ethanol, isopropanol, dimethylformamide, dimethylsulfoxide, dichloromethane or 1,2-dichlorethane with reduction being carried out using a triacetoxyborohydride, a cyanoborohydride or hydrogen and a catalyst, e.g. palladium. The O-demethylation may be carried out in an aprotic solvent, e.g. toluene, tetrahydrofuran, chloroform, dichloromethane or 1,2-dichloroethane.
Patent GB-2440757-A (GB)
Title: Controlling fuel supply to a combustor of a gas turbine engine
Inventor: PASHLEY NICHOLAS CHARLES
IPC: F02C9/28
Filed: 2006-08-10
Abstract: A system for limiting the minimum fuel supply to a gas turbine engine includes a processor 2, a calculating device 24 and a divider 10. The processor 2, which may include a look-up table, is adapted to derive a first value from a first set of engine operating parameters. The first value represents a minimum fuel flow requirement of a combustor multiplied by a factor, and the factor is derived by measurement of the engine inlet temperature and the engine inlet pressure. The divider 10 then divides the first derived value by the calculated factor to generate a second derived value at output line 14, which is multiplied by the combustor inlet pressure P3 to then generate a limiting minimum fuel flow requirement WFEMIN based on the second derived value. The minimum fuel flow to a combustor of a gas turbine engine is limited in response to the engine inlet temperature T1 and a coefficient X dependent on engine configuration and engine entry pressure P1, in order to provide a fuel air ratio (FAR) limit which responds to both factors. This enables the fuel flow to be limited such that the FAR is set to avoid unintentionally extinguishing the combustor flame and the rate of deceleration is maximized, regardless of ambient temperature and engine altitude.
Patent GB-2441554-A (GB)
Title: Ultrasonic anemometer
Inventor: PARKER SIMON TOBY
IPC: G01P5/24
Filed: 2006-09-11
Abstract: An ultrasonic anemometer capable of providing fluid (e.g. air or gas) velocity and direction data comprises at least one pair of ultrasonic transducers 5,6 which operate at a frequency less than 200 kHz (e.g. between 20 kHz and 150 kHz) and which are separated 7 by up to about 20 metres (e.g. between about 0.5 m and 10 m). The anemometer operates on the transit time principle. The anemometer allows velocity measurements in environments such as restricted spaces since the spacing between the transducers allows the transducers to be placed at either end of the space thus avoiding physical obstruction of the space.

Patent GB-2439451-A (GB)
Title: Retrofit TDI Stack Filter which intercepts Callback Commands and replaces them with Receive Commands allowing packet delays and traffic shaping
Inventor: DOUGLASS TOBY
IPC: H04L29/08
Filed: 2007-06-21
Abstract: Some computer network communications stacks use the Transport Dispatch Interface (TDI) protocol. This protocol provides two methods for moving data from the Transport Provider (TP) to the TDI Client (TC). The first (Fig. 1) is Callback whereby the TC gives the TP blanket permission to send any data it receives. The second (Fig. 1) is the Receive Command whereby the TP is given permission to send specific data, and must then wait for a further receive command before sending more. Some stacks do not provide the receive command functionality. This invention adds a TDI Filter between the TC and the TP, which intercepts the Callback registration sent by the TC. It then sends Receive Commands to the TP. The Receive Command can be used for introducing delays into the passing of data up the stack, and thereby can permit bandwidth shaping. Using the TDI Filter avoids the need to alter the existing programs.

The frame material 12, comprising plies 12<a>, and a plywood strip 5 are positioned on the core-half 8 by means of a peg 8<a>, and are bent around the core, preferably in the manner described in Specification 418,982 ; the frame material 12 is thereby bent into racket shape and the strip 5 is simultaneously bent into the form of an insertion, that is, a reinforcing piece adapted to extend around the inside of the racket head adjacent the throat thereof. Paper 9 prevents the adhesion of the strip 5 to the frame material 12, and paper 10 wrapped around the core-half 8 prevents the strip 5 adhering thereto. An insertion 6 previously made in the manner described above may be incorporated into the frame concomitantly with the bending of the latter into racket shape, the insertion 6 and wedge 11 being positioned on the core-half 7. The wedge 11 may be as described in Specification 418,985 or the wedge may be omitted. The insertion 5 may be temporarily secured to the core-half 8 on which it is made, by small, readily-disengageable spikes on the surface of the latter, or by adhering to the paper 10 ; the core-halves 7, 8, are interchanged for the next bending operation, when the insertion 5 will be incorporated into the frame as described above. Preferably, however, the insertion 5 is removed from the core-half on which it is made, and a stock of insertions kept for subsequent incorporation into frames.
