Abstract: ABSTRACT          GENETIC MARKER FOR DAIRY CATTLE PRODUCTION SUPERIORITY         An assay for determining the presence in bovine genetic material of a genetic marker located on the bovine somatotropin gene indicative of an inheritable trait of increased milk production is provided.  The marker is a polymorphism in the gene encoding somatotropin at amino acid position 126 which results in two forms of somatotropin existing in bovine. The assay comprises analyzing a bovine to determine its genotype with respect to the somatotropin gene.  Bovine with the desired marker can be selected for inclusion in breeding programs or for milking.  The desired marker indicative of superior milk production is dependent upon the breed of cattle.  Holstein cattle that are homozygous for the leucine forms of somatotropin are desired.  Jersey cattle that are homozygous for the valine form of somatotropin are desired.  A kit for performing the assay is also provided.

Inventor: WEBB WILLIAM T
IPC: H04L7/033
Filed: 1992-07-02
Abstract: A method of recovery timing information and a clock recovery system for digital data signals are described, in which a digital data signal is assessed to determine the occurrence of a peak in part of the signal and the suitability of that peak for providing timing information. In the clock recovery systems described a peak evaluator has a maximum peak detector (11) for determining the maximum oversampled value in a symbol period and the sampling point at which that maximum occurred; and peak score calculator (t2) for establishing a measure of the suitability of the peak by assessing the gradients of parts of the peak. The peak score associated with a maximum in the signal is compared with a similarly established minimum peak score by a comparator (3) and the larger provided to a switch (4) which, if the selected score exceeds a threshold; updates a phase lock loop (5), with the sampling point at which that peak occurred.

Title: Liquid dispensing apparatus
Inventor: WESTON COLIN K
IPC: B05C17/01
Filed: 1994-01-18
Abstract: A liquid dispensing apparatus is adapted to accurately dispense known volumes of liquid onto the receiving surface a workpiece, and comprises a cartridge having a reservoir for containing an amount of liquid. The cartridge has an outlet of known cross sectional area, and a piston adapted for longitudinal translational movement. There is a driving means for effecting movement of the piston, control means for operating said driving means, and means having a threaded portion for mechanically interconnecting the piston and driving means, so as to drive the piston within the cartridge. One of a first and second retaining means is securely connected to the piston and the other of said first and secondretaining means is securely connected to said cartridge, and the interconnectionmeans is longitudinally rigid between the first and said second retaining means so as to preclude unwanted relative movement of the piston with respect to the cartridge. Thus, when the piston is advanced along the cartridge towards the outlet, a known volume of liquid is dispensed. There is a feedback loop whereby the rate of liquid dispensing from the reservoir is substantially proportional to the rate of change in displacement of the outlet with respect to the workpiece, and varies proportionally as the rate of change in displacement varies.
