Title: Improvements relating to cranes and like lifting mechanisms
IPC: B66B1/04
Filed: 1941-10-31
Abstract: 554,375. Hydraulic machines. SMALLPIECE, C. D. P. Oct. 31, 1941, No. 14072. [Class 69 (ii)] [Also in Group XXX ] Mechanism for adjusting the load lifted by a crane to its final horizontal location comprises a cylinder 11 in which moves a piston 12 connected by a rod 13 to the load 14. A handlerotated valve plug 17 furnished with a bore 16 in permanent connection with a conduit 15 leading to the cylinder 11 has a radial vent 24 by which the interior of the cylinder can be put in communication with pipes 19, 20, 21, 22 at will. The pipe 19 leads to a pressure supply, the pipe 20 to a regulating valve, the pipe 21 to exhaust, and the pipe 22 to the balance chamber 26 of the regulating valve. On each side of the chamber 26 is a flexible diaphragm, one, 28, of which carries a needle valve 31 controlling an orifice 32 in a chamber 33 and the other, 27, carries a rod 29 slidable in a chamber 30. The rod 29 has a side extension forming a release valve for an opening into the chamber 30 connected to the supply pipe 19. In operation the vent 24 is first brought into line with the pipe 19 till the pressure entering the cylinder 11 is just sufficient to take up the whole of the weight of the load 14. It is then turned into line with the pipe 22 to bring the pressure inside the chamber 26 equal to that in the cylinder 11. This, if greater than the pressure in chambers 30 and 33, forces both diaphragms 27, 28 outward, the diaphragm 28 closing the valve 31, 32 tightly and the diaphragm 27 opening the inlet valve from the pressure supply. When the pressure inside the chamber 30, equalized through a duct 34 with that in the chamber 33, becomes the same as that in the cylinder 11, the inlet valve to the chamber 30, becomes closed. The plug 17 is turned to connect pipes 15 and 20 and the load 14 can then be raised or lowered by hand, in each case the change of pressure induced in the cylinder 11 being immediately compensated by opening of the valves in chambers 30 and 33 respectively, to restore the load balancing pressure in the cylinder 11. When the pressure fluid employed is a liquid, a bottle 36 provided with an air space 38 is connected to the chamber 26 to allow for proper functioning of the diaphragm 27 as liquid is forced from, or drawn into, the cylinder 11. Specification 545,318 is referred to.

Abstract: 1,179,237. X-ray analyser. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 28 March, 1967 [30 March, 1966], No. 14128/66. Heading H5R. An X-ray analyser comprises a specimen chamber 13, Fig. 4, which chamber is mounted on a first support plate 20, Fig. 5, which is adjustable along guides 22 and 23 along one lateral axis relative to a second support plate 21, which is adjustable relative to a base structure 11 along guides 24 and 25 along a second lateral axis which is normal to the first lateral axis, together with means for adjusting the specimen chamber longitudinally of its axis to assist in adjusting the specimen in the required focal plane. The X and Y lateral adjustments may be produced by rack and pinion drives as follows: the Y coupling rod 16 coupled to Y coordinate adjuster 9 in Fig. 4 drives gear-wheel 26 mounted on plate 11 and engages a rack 27 mounted on plate 21, and the X coupling rod 14 coupled to X co-ordinate adjuster 8 drives a gear-wheel 28 mounted on plate 21 and engages rack 29 mounted on plate 20. In an alternative embodiment the lateral movements are controlled by screw-threaded adjustment members acting on the support plates through bell crank levers against biasing springs. For the Z or longitudinal adjustment coupling rod17 coupled to adjuster 7 carries gear-wheel 30 mounted on plate 20 which meshes with gearwheel 31 which meshes with gear-wheel 32 mounted on shaft 33. Shaft 33, Fig. 6, carries gear 34 at its lower end which meshes with  internal teeth 35 of a rotatable annulus 36 the external face of which is screw threaded and engages a screw thread 38 on the inner face of casing 39, so that rotation of annulus 36 causes the annulus to move up or down in casing 39 against the action of springs 42. The focusing assembly 12 carrying the specimen holder is carried on annular flanged member 40 secured to the lower end of inner sleeve 41 supported by casing 39 by springs 42. The vertical positioning of the specimen holder is thus adjusted by screwing the annulus 36 up or down. A freewheel coupling is preferably included in the drive for moving the inner cylinder 41 longitudinally and it acts against a return spring so that the specimen may be moved forwardly independently of the drive. A brake which can be applied or released may be provided for rotating the specimen about its own axis and in this case the pin 46 and slot 47 in Fig. 6 is replaced by the brake. Optical means are provided for direct viewing of the specimen and a means for illuminating the specimen may be positioned either to illuminate the specimen on the same side that is viewed or alternatively on the opposite side so that it is seen with transmitted light. An optical polarizing adjustment means comprising a polarizing screen which can be rotated by the adjustment to vary the direction in which the projected light is polarized can be included.
