Polyol Compositions Polyol compositions comprising a polyol, an insoluble fluorinated compound and a surfactant composition which is the reaction product of a stoichiometric excess of a polyisocyanate and a polyalkylene glycol monoalkyl ether of formula R-A-OH, wherein R is C1-25 alkyl and A is a polypropylenoxy chain, optionally containing up to 25 % polyethylenoxy units, having a total length of...

Moulding Process The present invention provides a process for making a cured plastics moulding byintroducing a pre-heated curable resin composition to a hotter mould which is at a temperature high enough to initiate curing of the resin, and supplying further resin under pressure to compensate for shrinkage of the composition, wherein the curable resin is an epoxy resin formulation comprising an ep...

Despite the extremely flat construction, it is intended significantly to reduce the tendency of the semiconductor chip (1), which is embedded in the plastic housing (10) of the electronics module (M), to fracture. The chip is mounted on the chip island (22) of a system support (20) in the form of a sheet-metal structure (lead frame). The external contacts (21) - which can be partially covered by t...

A process for producing a saccharide carboxylic acid or a salt thereof characterized in that a microorganism belonging to the genus Pseudogluconobacter and capable of oxidizing a hydroxymethyl group and/or hemiacetal hydroxylassociated carbon atom to a carboxyl group, or an artifact derived from the microorganism, is permitted to act on a hydroxymethyl and/or hemiacetal hydroxylcontaining sacchari...

Device for the lubrication and cleaning, in particular, of chains and rails, having a plurality of saddle modules which exhibit, on the inner side, receiving grooves for the introduction of brushes. Fitted into the receiving grooves are brush modules which exhibit two brush legs and a brush web, comprising in each case brush spines and bristle clusters provided therein. The receiving grooves and/o...

The present invention provides a working fluid composition for a refrigerating machine obtained by mixing an ammonia refrigerant with a lubricating oil which is extremely excellent in solubility with the ammonia refrigerant, and a method for lubricating a refrigerating machine suitable for the use of the working fluid composition. The working fluid composition comprises a mixture of ammonia and on...

Disclosed are a method and a system for transmitting a message or data packet from a single sender (21) to a plurality, i.e. a group of receivers, usually called multicasting, within a conventional unicast transmission network, i.e. a network basically not equipped to handle such multicast transmissions, consisting of a plurality of subnetworks (22 - 24) The nodes or gateways (25 - 29) connecting ...

A veneer manufacturing process comprising placing a log within a work station, the work station having chucks at either end thereof for releasably engaging respectively ends of the log such that the log is rotatable about its longitudinal axis, and then rotating the log about its axis such that the rotating log may be brought into engagement with a blade system, The blade system extends along the ...

A method of operating a cross-fired regenerative glass furnace for melting flat glass so as to minimise emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method comprising supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is o...

FLAT GLASS FURNACES A method of operating a cross-fired regenerative glass furnace for melting flat glass so as to minimise emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method comprising supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required ...

A polymer composition containing a thermotropic liquid crystal polymer, polycarbonate and polyester. The polymer compositions are prepared by a two-step melt processing method which produces a unique microscopic morphology and improved toughness properties over conventional LCP blends.
