Patent GB-2283678-A (GB)
Title: Cryosurgical probe
Inventor: REEVES SIMON RICHARD
IPC: A61B18/02
Filed: 1993-11-09
Abstract: A cryosurgical probe comprises a probe head operable to be cooled by the expansion of a refrigerant gas within the probe head; a probe handle having means for precooling the refrigerant gas; and a flexible catheter linking the probe handle and the probe head, the catheter defining a channel for carrying precooled refrigerant gas from the probe handle to the probe head, and an exhaust channel for carrying expanded gas from the probe head to the probe handle. The refrigerant gas is precooled in the handle by allowing a major portion of the gas supply to expand through an aperture 120 into an expansion area 130. This expanded and hence cooled gas is then directed by a helically-vaned heat exchanger 140 in a helical path around a conduit 100, connected to the supply channel in the catheter and carrying the remaining portion of the gas supply. The probe also includes a sensor for detecting a sudden increase in the temperature of the probe head and a control arrangement, responsive to such a circumstance, for shutting off and venting the flow of the refrigerant gas to the probe head. <IMAGE>

Title: Eddy current detection of defects on metal components
Inventor: FLORA JOHN HARRIS
IPC: G01N27/90
Filed: 1993-12-07
Abstract: Defects such as corrosion on either the inner or outer surface of a covered metal component 44 are detected through eddy current inspection, using at least two magnetising yokes 10a, 10b held fixed with respect to each other by a common excitation coil 20. The yolks are scanned over the cover of the component 44. A magnetic flux sensor 30 preferably on the leg of each yoke 10a, 10b detects changes in the magnetic flux that penetrates different depths into the covered metal component 44, depending on the relative position of each magnetizing yoke 10a, 10b. Sensors 30 may be located on one or both legs of the yolks, and each yolk may have more than two legs, each leg having its own sensor. Sensor coils may be differentially connected. <IMAGE>

Title: Self-cleaning liquid screening apparatus with level sensor
Inventor: HARRIS LEONARD
IPC: B01D29/11
Filed: 1995-07-27
Abstract: A drum chamber 10 has a liquid inlet 44 for water containing solid waste. A rotatable screening drum 12 is mounted in the chamber with a substantially horizontal axis, to allow inward filtration. The drum is stationary while filtration occurs. The side wall of the drum 12 is formed by screening mesh 20 supported on external axial bars 22. One end of the drum is sealed against a side wall 26 of the chamber containing an opening 28 to form a weir that determines the level of filtered liquid in the drum.
