Patent EP-0294109-A2 (EP)
Inventor: DAVEY R J
IPC: B41M5/26
Filed: 1988-05-26
Abstract: A thermal transfer dyesheet, comprising a supportive base material coated with a composition of a thermally transferable dye dispersed uniformly throughout a polymeric binder matrix, also contains in its coating composition a crystallisation inhibitor having a molecular structure consisting essentially of a polymer backbone to which are chemically bonded a multiplicity of groups having substantially the same shape, charge distribution and hydrogen bonding pattern as the dye or substantial portion thereof. 
     Provision of such crystallisation inhibitors serves to reduce the problems of roughness on the dyesheet surface, and the dirty surfaces which both have tended to occur in previous dyesheets as the dye molecules migrate to the surface and combine to form crystals there.
Patent EP-0319133-A2 (EP)
Inventor: DUNHAM BYRON J
IPC: G01N29/024
Filed: 1988-10-18
Abstract: Hand-held apparatus for detecting presence of halogen refrigerant agents in air in which a pair of ultrasonic transducers (34, 36) are spaced from each other within a measurement probe (18) and test air is continuously drawn between the transducers by a fan (44). One transducer (34) is energized at constant ultrasonic frequency, and the other transducer (36) is coupled to a rectifier or a phase detector (72) for providing a measurement signal as a function of radiation received at and reflected by such other transducer. A reference signal level is established by selectively sampling and electronically storing of the measurement signal, such that the reference level is automatically or manually updated to reflect changes in ambient conditions. An audio/visual alarm (30, 32) is activated when the measurement signal departs from the ambient reference level by more than a preslected threshold.
Patent EP-0317135-A2 (EP)
Inventor: KEEGAN SANDRA ANN
IPC: D06M15/647
Filed: 1988-11-03
Abstract: This invention relates to fabric conditioning formulations which contain siloxanes having a Cs + alkyl subsituent and which optionally have, in addition, polyoxyalkylene substituents. The presence of C s  + alkyl substituents to improve the rewettablity of the fabrics conditioned therewith.
Patent EP-0318189-A2 (EP)
Inventor: BUSH JAMES WILLIAM
IPC: F04C18/02
Filed: 1988-11-11
Abstract: A scroll compressor is disclosed in which either or both of the spiral wraps (24,30) of the scroll members are reduced in thickness (i.e., cut away) (A, E) adjacent to the inlet port (34) defining the starting point the vanes would theoretically sealingly engage one another to initiate compression. Additionally, either or both of the spiral wraps of the scroll members may be reduced in thickness (J-K, L-M) (i.e. cut away) adjacent to the discharge port where the vanes separate and the compression chambers defined thereby communicate with the discharge port. Provision of a smooth transition (C-B) at the points of engagement cooperates to reduce noise and wear during operation of the compressor.
