Title: Electrophoretic analysis of carbohydrates using 2-aminoacridone label
Inventor: JACKSON PETER
IPC: C12Q1/44
Filed: 1991-12-20
Abstract: The present invention provides for the use of the fluorescent label 2-aminoacridone for use in separating carbohydrate mixtures and analyzing the structure of carbohydrates. Carbohydrates for analysis may be labelled by 2-aminoacridone and subsequently separated from one another by electrophoresis. The electrophoresis may be in one or two dimensions. Band produced by the electrophoresis may be visualized and quantitated directly by UV illumination or by means of a charge coupled device for photoelectric detection. 2-aminoacridone labelling of carbohydrate may also be used to analyze the structure of carbohydrates by cleaving (or adding to) various 2-aminoacridone labelled carbohydrates by carbohydrate modifying enzymes of known specificity, and subsequently separating the carbohydrates by electrophoresis in either one or two dimensions. The subject invention also provides for kits for performing 2-aminoacridone labelling and electrophoresis.

Title: A valve assembly
Inventor: THOMAS STEPHEN WESLEY
IPC: F16K1/46
Filed: 1993-10-08
Abstract: A valve assembly, suitable to fit to a rising stem tap in which flow lifts the valve member, comprises a tubular member (20) having a bore which provides a path for the fluid flow. An annular seal member (25) is retained in a channel (28) around the inside of the tubular member (20).

IPC: F02D41/02
Filed: 1995-08-26
Abstract: A multi-cylinder spark ignition internal combustion engine is described having two banks of cylinders 10a, 10b. One bank of cylinders may be selectively disabled by cutting off its fuel supply while continuing to receive air.

IPC: H01Q13/22
Filed: 1996-04-18
Abstract: A radiating waveguide comprises an elongated waveguide 10 with a transverse cross-section dimensioned to carry only a dominant mode at a selected operating frequency.
