Abstract: 1419357 Drill chucks METABOWERKE KG CLOSS RAUCH & SCHNIZLER 3 July 1974 [14 July 1973] 29415/74 Heading B3B [Also in Division B4] A chuck for a percussive drill comprises a setting sleeve toothed rim unit 15 having a tapered thread 8 which co-operates with threads 7 on clamping jaws 5, a dished spring 23 non- rotatably mounted on the chuck body 1 which frictionally engages the upper shoulder 26 of toothed rim unit 15 during the final tightening of the clamping jaws to prevent rotation of the toothed rim unit. When a tool is mounted in the chuck rotation of the toothed rim unit 15 causes, through threads 7, 8, the jaws 5 to clamp the tool. Further rotation of the toothed rim unit, due to axial play in its mounting, causes it to move upwards relative to the chuck 1. Spring 23 which normally engages an edge 20 on the chuck body is engaged by the rising toothed rim unit which then takes the whole spring force which frictionally locks it against rotation during use.

Abstract: 1,164,688. Detecting atmospheric turbulence photo-electrically. NORTH AMERICAN AVIATION Inc. June 27, 1967 [Nov.16, 1966], No.29673/67. Heading G1A . Atmospheric turbulence is detected by a radiometer which scans a 90 degree field in front of the aircraft carrying it and indicates changes of temperature associated with turbulence. A filter is provided to limit the radiation received to a 1 micron wide band centered about 13À5 microns which is on the edge of the 15 micron emission/absorption band of CO 2 , with the result that the radiometer measures the temperature of the atmosphere in a column extending about 50 miles from the radiometer. A chopper is provided whereby the radiometer receives radiation alternately from the atmosphere and a black body at a reference temperature. The radiometer signal is rectified and filtered to provide an atmospheric temperature signal which may be applied to the Y deflection of a cathode-ray tube, the X deflection being synchronised with the radiometer scan, Fig. 4, (not shown). The atmospheric temperature signal is sampled at times corresponding to 45 degrees left, dead-ahead and 45 degrees right by a circuit 40, Fig. 12. The dead-ahead signal is fed to a storage circuit 44 which compares the signal with its value one minute previously and displays the difference on the meter 46. If the difference is sufficient to indicate turbulence a lamp 51 flashes to apprise the pilot. The dead-ahead signal is also fed with the left and right signals respectively to comparators 62, 63 and any differences are displayed by meters 47, 48 and warning lamps 52, 53. A comparator 68 compares the atmospheric temperature signal with a probe 80 measuring the atmospheric temperature in the vicinity of the aircraft, and if the difference is greater than 2‹C the gain of amplifiers 45, 64, 65 is reduced and lamp 55 is lit to indicate the presence of ice crystal clouds. A wider angle detector is provided to sense when the sun is near the field of view of the radiometer and close a shutter in front thereof to prevent damage.

Filed: 1955-10-27
Abstract: A mixture of liquid hydrocarbons suitable for use as an aviation fuel component, is obtained by separating a fraction having an initial boiling point of 65 DEG  to 85 DEG  C. and a final boiling point of 130-140 DEG  C. from a naphthenic straight-run gasoline, catalytically reforming the fraction and removing from the reformate by fractional distillation, a fraction boiling between 85 DEG  and 105 DEG  C. consisting principally of C7 paraffins.  In an example, a gasoline fraction boiling between 65 DEG  and 135 DEG  C. was separated from a naphthenic gasoline by fractional distillation. This fraction which contained about 51 per cent by weight of naphthenes was passed over a commercial platforming catalyst at a rate of 2.1 litres per litre of catalyst per hour together with a recycle gas containing 95 per cent by volume of hydrogen per mol. of gasoline fraction, at elevated temperature, and at a pressure of 26 atmospheres.  After stabilizing the platformate, it was then split in a column into a fraction boiling above 105 DEG  C. and a lighter top product which was then split into a product boiling up to 85 DEG  C. and the two fractions blended, optionally with the addition of an alkylate prepared from isobutane and a mixture of butenes and pentenes.
