Title: Grain refiner for aluminum containing silicon
Inventor: SIGWORTH GEOFFREY K
IPC: C22C21/00
Filed: 1986-03-06
Abstract: Disclosed is an Al-Ti-B master alloy consisting of 0.1 to 9.8% Ti, 0.1 to 7% Boron balance Aluminium plus impurities designed to grain refine cast aluminum alloys containing silicon. The alloy composition goes contrary to present known art. Present commercial master alloys contain a ratio of Ti to B exceeding 2.2 to promote a mixture of TiB2 and TiAl3 crystals. This invention provides an Al-Ti-B alloy wherein the Ti to B ratio is between 0.1 and 2.1. It contains a preponderance of mixed boride crystals. The optimum composition of the alloy of this invention is Al-3Ti-3B.

Title: Electromagnetic transducer assemblies and means for determining relative speed and/or configuration using such assemblies
Inventor: HORE DONALD LIONEL
IPC: E21B47/12
Filed: 1986-05-06
Abstract: A first component is caused to produce a varying magnetic field. At least one second component detects this field and from the nature of the variation, information about the relative position, configuration or rotation of the components is derivable. The first component may have a rotary shaft 10 carrying a magnetisable bar 14 fixed at an angle; and an exciting coil 16 for inducing magnetism in the bar. If the coil carries an a.c. current and the shaft rotates, the bar produces a gyrating field. This induces in a detector coil 22 a varying EMF whose characteristics depend on the rotation rate and on the relative disposition of the coil. With a plurality of detector coils, detailed information about relative positions and orientations is derivable from the EMFs. Either the detector coil or coils, or the arrangement for producing the gyrating field may be mounted on an earthworking mole. <IMAGE>
