A magnetic theft detection system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) have selected tones that provide the marker with signal identity. The marker is an elongated, ductile strip of amorphous ferromagnetic material having a value of magnetostriction near zero that re...

A system for heat-sealing thermoplastic conduits involves a thermoplastic sleeve surrounding an electrically conductive heating wire arranged in a coil. A bridging conductor is located adjacent the heating element, but is separated from it by an insulation layer of predetermined thickness. When the sleeve is heated by supplying electric power to the heating element, the entire heating element gene...

Metallic silver is deposited from a silver salt solution onto a support by reduction, and thus a catalytically active electrode material for oxygen-consuming electrodes is obtained. For this purpose, (a) an aqueous dispersion of a hydrophobic polymer, in particular a dispersion of PTFE, (b) a silver salt solution and (c) reducing agent for silver ions are mixed. During this, a pH at which the disp...

The core is spray coated with a metal or alloy having a melting temp. T1. This is coated with an insulation layer of melting temp. T2. The core is then put in a mould and metal added at a temp. less than T1 or T2. Finally, the core is cleaned out to leave the finished component.

The apparatus comprises securing units which each comprise a supporting device 4 for the upper jaw of a split hog-head and the associated skull portion as well as a supporting device 5 for the lower jaw of the split hog-head in question. The upper jaw supporting device and the lower supporting device are mutually turnably connected by means of a hinge 15 and comprise securing means 6, 26 and 11, 3...
