S P E C I F I C A T I O N "Improvements in or Relating to Instruments for Monitoring the Direction of a Borehole" An instrument for monitoring the direction of a borehole comprises an elongate casing having its longitudinal axis coincident, in use, with the axis of the borehole, an outer gimbal pivotally mounted within the casing with its pivot axis coincident with the longitudinal axis of the cas...

A vehicle gearbox has a brake for dampening idle rattling, which is in this case in the form of a conical frictional surface on the low-speed gearwheel on the output shaft and a brake cone carried by a disc fixed to the output shaft. The disc and the cone have coacting structure which presses the cone against the frictional surface when the low-speed gearwheel rotates more rapidly than the output ...

Rubber crumbs which are suitable for storage can be produced by charging the rubber crumbs with an organic or inorganic powdering agent before the final drying in the process sequence, screw dehydration, screw drying, reducing the rubber strand to crumbs and final drying.

A freely standing thin pellicle film of cellulose acetate butyrate is formed by spinning on a rotating substrate. After forming, the film is lifted off of the substrate and secured to a metallic frame. The pellicle is for use in the mid ultraviolet range of 280 to 360 nanometers, but can be used also in the deep ultraviolet range, e.g. wavelengths as low as about 240 nanometers. The pellicle preve...
