A coating composition for use in a mold coat coating process wherein the coating composition is previously coated on the molding surface of a mold for polyurethane resin, prior to molding of the polyurethane resin in which the coating composition is transferred onto the surface of the molded polyurethane resin. The coating composition is comprised of a principal component including a resin constit...

Samples are taken from the tissues thereby that certain parts thereof are pyrolysed punctiform and the pyrolysate so obtained is collected and its composition is examined and the results of this examination are compared with reference data. Thereby the character of the tissue is determined, whereafter samples are taken repeatedly and the boundary of the tissues is indicated and the separation is p...

A vehicle guidance system for a tractor has a horizontal scanning laser on the tractor and a target arranged to return the laser beam along its path. When returned laser light is detected, indicating alignment of the beam with the target, the angle of the beam relative to the tractor axis illustrates the steering correction required. The target has an array of beam reflecting elements patterned to...

Packages 10 on a conveyor 152 are photographed as they pass a camera 156 and the image is displayed by liquid crystal display screen 30. Laser 158 illuminates the two-dimensional image which is focussed by a cylindrical lens 42 to a line image on a linear detector 160. Peaks in the intensity of the line image represent by position and amplitude lines in the two-dimensional image which extend trans...

Borehole surveying methods and apparatus for surveying the true longitudinal magnetic field within a substantially non-magnetic drill collar occupying the part of a borehole being surveyed, despite the collar being of insufficient length to provide longitudinal magnetic field measurements which are uncorrupted by the longitudinal magnetic influences of adjacent magnetic drill string and bottom-hol...

A composite material of low dielectric constant is produced by subjecting a mixture of polytetrafluoroethylene and minute hollow spheres of insulating material such as glass to shear stress to impart a fibrous structure to the polytetrafluoroethylene and optionally thereafter sintering the material.

A differential engagement friction clutch (5) with an axially displaceable actuating element (8) and a spring (11) for opening the friction clutch (5), in which the actuation element (8) is controlled by a viscous coupling (6) operating in paralled to the friction clutch (5), with a torque which increases with the difference in rotation speed. The torque of the viscous coupling (6) produces, via c...
