Abstract: A linear abstract includes a cylinder part and a piston part. A spring connects the cylinder part and the piston part and operates in the direction of reciprocation of the piston part relative to the cylinder part. The piston part includes a radially compliant but axially stiff linkage and a piston. The cylinder part includes a cylinder and a cylinder liner therewithin. A bore runs through the cylinder liner and the piston reciprocates in the bore. Gas bearing passages are formed between the cylinder and the cylinder liner leading to openings through the wall of the cylinder liner to the bore. A gas bearing manifold receives compressed gases and supplies the compressed gases to the gas bearing passages. The gas bearing passages follow a tortuous path to the openings.

Abstract: A method of operating a drain pump in a laundry washing machine during the drain phase of the wash cycle to reduce pump blockages is disclosed. The method includes the steps of (a) starting the pump and running it for a first period of time to produce a discharge of a given flow rate, (b) stopping the pump and leaving the pump stopped for a second period of time, and repeating steps (a) and (b) for the duration of said drain phase, said second period of time being such that the flow rate reduces substantially to zero.

Abstract: A refrigerator has a fresh food compartment (3) adapted for maintaining the contents at a temperature above freezing. A vapour compression refrigeration system is operable in one mode so that an evaporator (7) is operated at a temperature within 10° C. of the temperature desired in the fresh food compartment (3) and a supply of air is maintained over the evaporator (7) and in to the compartment (3). The vapour compression system is used in a defrost mode in which the vapour compression refrigeration system is stopped or allowed to operate without significant heat extraction at the evaporator (7), and a supply of air above 0° C. is past over it. Operating the fresh food compartment evaporator (7) at such a high temperature (close to 0° C.) reduces the rate of frost build up and the under cooling of frost. Frost may be adequately removed by an ambient air flow without heater supplementation.

Abstract: A process for the preparation of a compound having the formula R3R4P—Ar—CO—X wherein Ar is an aryl group bearing the PR3R4 and COX groups in a 1,2-relationship, and optionally bearing also one or more non-interfering groups, R3 and R4 are each a hydrocarbon group optionally substituted by any non-interfering group, and X is OH or a non-interfering group, comprises (i) the reaction of NaPR3R4 with F—Ar—COX, or (ii) when X is an amine group, the reaction of R3R4P—Ar—COOY, OY being OH or a leaving group, with a solution of the amine obtained in situ by adding a base to a salt thereof. Certain ligands prepared by such a process are in a novel, crystalline form.

Abstract: An enantiomerically enriched compound of formula 1, wherein Ar is phenyl optionally substituted with one or more groups selected from haloalkyl, alkyl and halide. This compound can be isolated in crystalline form, and used in the preparation of (+)-16-[3-trifluoromethyl)phenoxy]-17,18,19,20-tetranor PGF2&agr; isopropyl ester.

Abstract: The invention provides nucleic acids that encode a first glycosyltransferase that competes with a second enzyme for a substrate, thereby reducing the formation of a product of the second enzyme. The nucleic acids are useful in producing cells and organs with reduced antigenicity and which may be used for transplantation.

Abstract: The present invention pertains to a process for the preparation of an arylphosphine of the formula R1OC—Ar—PR2R3 wherein Ar is aryl or heteroaryl; R1 is an alkoxy or amine group; and R2 and R3 are each any organic group; and each of the respective groups may optionally be substituted with any non-interfering group; which comprises the reaction of a sulfonyloxy compound of the formula R1OC—Ar—OSO2R4 wherein R4 is alkyl, haloalkyl, perhaloalkyl, aryl, aralkyl or alkaryl, with a phosphine of the formula HPR2R3, in a solvent and in the presence of a palladium catalyst and a base. The arylphosphine can then readily be converted to a chiral phosphine ligand.
