IPC: B64C25/60
Filed: 1960-12-17
Abstract: 949,395. Hydro-pneumatic shock absorbers. FLUGZEUGWERKE DRESDEN VEB. Dec. 17, 1960, No. 43516/60. Heading F2S. An hydro-pneumatic shock-absorber for aircraft undercarriages comprises a piston-rod 5 which carries respectively detachable upper and fixed lower pistons 6, 7 which, with their sealing rings 20, work in a cylinder 2 and enclose a constant capacity control chamber 26 which is filled with hydraulic fluid through an opening 30 and which is sub-divided by adjacent orifice rings 8, 9 which are secured by three-part retaining and spring rings 15, 16 and are provided with flow orifices 27, 28 controlled respectively by exteriorly-located valves 11, 12, a control rod 17, with a transfer opening 18, being secured between the pistons 6, 7. Sealing rings 21 are accommodated in recesses in the inner wall of the cylinder 2 adjacent the lower orifice ring 8, a cover-plate 10 for a passage 29 in the ring 8 being located in a chamber between the rings 8, 9 and provided with a sealing ring 22. The cylinder ends are closed by a screw cap 2 co-operating with a washer 19 and a cover-plate 3 containing a bearing for the piston-rod 5. The rod 17 may be replaced by a spill valve and spring on the ring 9, and the chambers 25, 26 may intercommunicate through channels in the upper piston 6 in which case the pressure chamber 25 must be filled with a compressible fluid. In use, the chamber 25 above the piston 6 is filled, e.g. with compressed air, through a valve 4 to fully extend the shock-absorber under normal load, e.g. when the aircraft is stationary. When the shock-absorber is loaded liquid is displaced through the orifices 27, 28, 29 in the rings 8, 9 from the lower to the upper part of the control chamber 26 the transfer channel 18 in the rod 17 providing an unimpeded passage through the ring 19 when excessive upward displacement of the pistons 6, 7 occurs. Decompression causes liquid to return to the lower part of the control chamber 26 through the valve controlled orifices 27, 28.

Abstract: 952,578. Roll holders. P. JEND. Nov. 19, 1962 [Nov. 20, 1961], No. 43584/62. Heading A4G. A wall bracket for holding a roll comprises a roll holding member 2, 9, a securing member 3, 11 and a mounting 1 in which axles 15, 16 on both members are mounted for rotation through a semi-circle and are constructed to prevent the members being separated from the mounting when the latter is secured to a wall, the free ends of the members having respectively a projection 10 and an opening 12 whereby they may be secured together to hold the roll by resiliently bending the holding member and in which the free ends may be disengaged only in a predetermined position of the members with respect to the mounting in which the axle of the holding member, which is of non-circular section fits into a corresponding groove of the mounting. The axles each have a lateral end tab whereby they can only enter the bore 8 of the mounting with the tab passing through the groove 7, when the mounting has not been fixed to a wall. With the mounting on the wall the axles become inseparable therefrom. Axle 16 has a limited amount of horizontal movement whereby the catch 17 on the holding member snaps secure through the opening 12 in the free end of the securing member due to the flexure of the arm 2. When the roll has been used the arms 2, 3 are substantially vertical and flaps on the axle 15 permits the holding member 2, 9 to be hinged at the point x with the flattened axle entering the groove 7 whereby the catch 10 may be released from the hole 12.

Abstract: 1,071,156. Anchoring cables. CHEVRON RESEARCH CO. Nov. 5, 1963 [Nov. 5, 1962], No. 43602/63. Heading B8B. [Also in Division E1] At a submerged well a guide-line 61 may be disconnected from or connected to a submerged post 44 adjacent the well by means of a television camera and a guide arm which has frictional gripping means engaging the fitting 62 at the end of the line. When the fitting 62 has seated on the post and a pin 73 has sheared a piston 71 is forced upwardly by a spring 72 to force balls 74 to extend out of ports 75 in a sleeve 70 to engage a groove 77 on the interior of the post 44 to provide the connection between the post and fitting. The fitting is disconnected from the post by dropping a weight 80 down the line so that spring latches 481, 482 engage a flange 326 on the sleeve 70 and move the piston by compressing the spring 72. The movement of the piston frees the balls from the groove so the fitting may be disconnected by a pull on the line. In a modification (Fig. 13, not shown), the fitting has a screw connection to the top of the post and the connection is made or broken by rotating the drill string.

Apparatus for the photo-electric determination of light scattering comprises a liquid container, a light absorbing device within the container, means passing a beam of light into the container, a device within the container for sampling the intensity of light around a point in the incident beam and means for comparing the intensity of the sampled light with the intensity of the incident beam. Test liquid in a container 1 having black walls 2 angled to absorb stray light is illuminated through a window 3. Light scattered at a point 8 is reflected by a mirror 9 into a probe tube 6, so as to strike the surface of a lens 7 normally. The probe tube is rotatable about an axis 5. The scattered light is transmitted by a prism 10,or mirrors or fibre optics to a photo-multiplier on which it is incident alternately with reference light direct from the source of illumination. The A C. signal from the photo-multiplier drives an attenuator in the reference beam to balance the beams, the attenuator position being recorded against probe angle to give a polar plot of light scatter. In modifications, baffles may be provided for absorbing light, the incident light beam may be introduced by mirrors or fibre optics and the optical melt balance system may be replaced by a ratio recorder. The recorded variables can be transmitted to a computer on punched tape.

Abstract: 1378508 Rolling FORMFLO Ltd 2 Oct 1972 [7 Oct 1971] 46833/71 Heading B3M A cylindrical workpiece of constant diametral size is produced by rolling a cylindrical workpiece between at least two forming rolls 12, 14 whose innermost advanced position or the dwell time in the advanced position is varied in dependence on the variation of the workpiece dimensions from the dimensions of a nominal workpiece which would produce the desired final workpiece dimensions under standard roll advancement extent and dwell time. The rolls 12, 14 are mounted in yokes 16 operated by hydraulic piston-cylinder units 20. In one embodiment the extent of roll advancement of each roll is varied by a screwed adjustable stop 36 operated by a stepping motor 44 driven manually or by a device 40 which measures the workpiece size and computes the volume variation from the nominal size of workpiece. In an alternative embodiment the device 40 computes an appropriate dwell time from the volume variation. The dwell time is controlled by a pressure sensitive switch 50 and a timer 52 preset by the device 40.
