Title: Improvements in hydrostatic tube testing equipment
Inventor: BELL GEORGE
IPC: G01M3/28
Filed: 1963-09-02
Abstract: 1,021,725. Testing hollow tubes. HIGH PRESSURE COMPONENTS Ltd. Dec. 1, 1964 [Sept. 2, 1963], No. 34605/63. Heading G1S. Apparatus for testing by pressure the strength of a flanged tube comprises a closure device for sealing the end of the tube 1, the closure device comprising a tapering core 4 which has a divided gripping ring 5 mounted on its tapering surface and a stem 3 extending from its smaller end, an L-sectioned closure ring 20 with a seal 23 around one face which is arranged to seat against the face of a flange or other end face on the tube, a closure plate 14 fitting on the stem 3 and having a peripheral seal 20a fitting in the closure ring, and a clamping device 25 for moving the plate on the stem towards the core so that the closure ring is pressed against the end face and the core is forced through the gripping ring to anchor the device in position, the pressure introduced into the pipe tending to move the plate, and with it the core, outwards so that the grip of the ring 5 is increased, but the closure ring remains firmly sealed against the end face as the plate moves relatively to the closure ring. In use, a nut 25 is first unscrewed to contract the nut fully and the core 4 and ring 5 are inserted into the tube until the rubber rings 23 contact the flange 2. The nut 25 is then tightened transmitting a thrust through the packing ring 26, the closure plate 14, the rubber ring 18, the shoulder 19 and the spacer tube 11 to the ring 5 which moves the ring inwards thus expanding it to grip the internal surface of the tube. Further tightening of the nut causes compression of the ring 18 and a tighter contact between the rings 23 and the flange 2. Both ends of the tube are sealed with similar devices except that one is adapted to allow for the insertion of the water and the device shown is adapted for the removal of the air. The water under pressure produces an outward thrust on the core 4 tending to jam the gripping ring tighter against the tube wall. The water also passes around the square-sectioned ring 6 into a space 21 between the closure ring and closure plate where it provides an additional force to maintain the seal between the closure ring and the flange.

Title: Improved Patterning Mechanism for Circular Knitting Machines
Inventor: WIDDOWSON ALBERT HENRY
IPC: D04B15/66
Filed: 1967-07-28
Abstract: 1,160,100. Knitting-machines. WILDT MELLOR BROMLEY Ltd. 22 July, 1968 [28 July, 1967], No. 34776/67. Heading D1C. Needle selection is achieved in a circular machine by the provision of a jack 7 beneath each needle having an outwardly sprung end 7c containing a butt 7d on its extremity adapted to engage a needle clearing cam 8 when permitted to remain in its projected position from the needle cylinder trick. In front of each jack is positioned a fulcrummed presser member 11 pivoted at 12 and carrying a butt 11b at its lower end which when engaged by a cam 24 prior to a selecting station urges the lower end of the presser member inwardly and simultaneously presses on the jack 7 to urge its butt inwardly away from interaction with the cam 8. The upper ends of the presser members are provided with butts 11a selectively broken away to leave a contrasting arrangement of butts 11a over the whole series of presser members. Adjacent the butts 11a at each selecting station is a 'bank of electro-magnets 15 one at each height of the butts 11a. The electro-magnets are energized under the dictates of a punched film permitting light to influence a corresponding series of photo-electric cells which in turn actuate the electro-magnets. Consequently any electromagnet 15 so energized will cause its magnet to hold the presser members by their butts 11a as the latter engage the magnets after the presser members have been deflected by the cam 24. Those electro-magnets not energized fail to retain the corresponding presser members and the end 7c of the jack 7 is allowed to spring out after the pressers have passed the cam 25 whereupon the butt 7d engages the cam 8 and the corresponding needle is raised to clearing height.

Title: Scale for calibrating electron beam instruments and method of fabricating the same
IPC: H01J37/26
Filed: 1977-08-23
Abstract: A microscopic length scale typically about 50  mu m long and graduated in several intervals ranging from 1  mu m to 20  mu m. The scale is useful in calibrating the magnification of scanning electron microscopes (SEMs) and other electron imaging instruments. The scale comprises alternating layers of two metals deposited on a substrate. The two metals have substantially different electron emission coefficients to provide contrasting emission signals when scanned by an electron beam. One of the metals, preferably gold, is deposited in uniform layers about 40-80 nm thick. The other metal, preferably nickel, is deposited in several layers ranging from 1  mu m or so thick near the substrate to 20  mu m thick in the outermost layer. The resultant multilayer composite is cut into one or more samples and each sample is mounted on edge. The exposed edge is ground and metallographically polished and a microscopic indentation is made in the substrate near the first gold layer. The indentation defines a reference region, and the distances between the first gold layer and the subsequent gold layers in the reference region are measured. The measurement is made using a similar sample which was previously calibrated with the aid of a polarizing laser interferometer.

Abstract: 1471750 Oil sump DAIMLER-BENZ AG 13 Aug 1974 [16 Aug 1973] 35644/74 Heading F1B [Also in Division F2]  An oil sump 10 comprises a central chamber 14 with apertures 23, 24 located in sidewalls 15, 16 of the chamber near its end-walls 18, 17, the endwalls being joined to the sump sidewalls 31, 32 by baffles 27, 28, thereby forming outer chambers 29, 30. A baffle 35 divides chamber 29 into sections 29a, 29b, which communicate via an opening 37, a similar baffle being located in chamber 30. Oil is extracted from the sump via a suction cage 21 by a pump 20. If oil within the sump surges toward end-wall 33, the oil within central chamber 14 rises against wall 17 and that within outer chamber 29 rises against wall 28; a pressure difference results owing to the greater length of chamber 29 over chamber 14 resulting in oil passing through aperture 24 into chamber 14 thereby reducing the chance of air entering the lubrication system. Similarly, oil enters chamber 14 via aperture 23 if it surges toward end-wall 34. Similarly, transverse surges result in a pressure difference preventing oil from leaving chamber 14 and may result in oil entering the chamber. These effects also occur if the sump is tilted about either a longitudinal or transverse axis.
