Abstract: 1481748 Fluid-pressure servomotor systems ARTHUR PFEIFFER VAKUUMTECHNIK WETZLAR GmbH 24 Oct 1975 [31 Oct 1974] 43708/75 Heading G3P A vacuum pump 17 has a pneumatically operated stop-valve 15, 16 in its suction duct, the valve being controlled by an electromagnetic valve 8 supplied with electric current from a generator 9 driven by the pump drive-shaft 10. During normal pumping the valve 15, 16 is held open by gravity and/or a spring 21, the electromagnetic valve 8 being energized to its closed position by the generator 9. If the pump ceases to operate, the fall in the generator output allows gravity or the spring 21 to open the valve 15, 16 whereby gas from atmosphere or the pump outlet 20 is admitted to a chamber 19 to act on a piston 14 and thereby close the valve 15, 16. Re-starting the pump causes closure of the valve 8, whereafter the pump evacuates the chamber 19 via a restricted clearance around the piston 14 and a passage 18 before the spring 21 and/or gravity acts to re-open the stop-valve.

Title: Improvements in or relating to an adjustable table assembly
IPC: A61B6/04
Filed: 1960-12-29
Abstract: 941,189. X-ray examination tables. LABORATORY FOR ELECTRONICS Inc. Dec. 29, 1960 [Dec. 30, 1959; Dec. 5, 1960], No. 44686/60. Heading H5R. [Also in Division A4] An adjustable table assembly such as an X-ray examination table has a supporting means connected to the table structure by a first pivotal axis and connected to a base member by a second pivotal axis, so that the table can pivot relative to the support about the first axis, and the support itself can pivot relative to the base about the second axis; both pivotal movements can be effected simultaneously, together with elevation of the table strutture. In one form, the table is a rectangular boxlike structure, having an upper surface 20 and side panels 21. It is supported above a base 15 by links 8, 9 which can extend in telescopic fashion. These links are pivotally connected to the table at pivots 2, 3, and to the base 15 at pivots 4, 5 respectively. The links are themselves connected together by links 12, 13, which are pivoted at one end to the first links at 10, 11, at the other end to a common pivot 14 which rides in the vertical part of a T-shaped slot 16 in an upraised portion of the base. The links 8, 9 are hydraulic cylinders, and are telescopically extended by hydraulic fluid pressure through supply lines 50, 51. Fig. 2 shows the table disposed horizontally in its lowermost position, with the telescopic links 8, 9 fully retracted. Fig. 4 shows the table still horizontally disposed, but elevated in height, the telescopic links 8, 9 being extended by equal amounts. This has caused them to rotate towards each other about pivots 4, 5, so that pivot 14 is driven upwards in slot 16. Fig. 5 shows how the table is tilted, by extending only one of the telescopic links; when this is extended to its fullest length (position c) the table is tilted through 90 degrees to a vertical position. Thus as the table tilts from the horizontal to the vertical position, it rotates about pivot point 3, pivot 3 itself meanwhile rotating somewhat about pivot point 5 as the link 9 is pulled inwards from position a to position c. The tilting can be initiated from the lowest horizontal position of the table (Fig. 2), by extending one telescopic link only. If it is initiated from the raised horizontal position of the table (Fig. 4), one link is retracted from its partial extension, while the other is further extended to its maximum. In the modification of Figs. 6 and 7 (not shown), the hydraulic telescopic links are replaced by a system of follower blocks operated by lead screws. A programming system can be devised for automatically causing the table to take up a preselected degree of elevation or tilt by actuating a corresponding switch.

Abstract: 1,127,780. Refrigerating. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 22 Oct., 1965 [26 Oct., 1964], No. 44818/65. Heading F4H. The cooling-down period of a cold-gas refrigerator immediately after start-up is shortened by operating the refrigerator at a higher working pressure, and hence a higher efficiency, than under normal operating conditions. As shown, the working space of a cold-gas refrigerator 10 communicates through duct 20, valve 16 and duct 30 with a container 32 and through duct 23, valve 22 and duct 25 with a receiver 24, the latter being connected to duct 30 by a duct 26 containing a non-return valve which only permits flow from duct 30 to container 24. Valve 16 is controlled by a switch 12 responsive to the cold head temperature of refrigerator 10 and is arranged to open at a predetermined low temperature to supply working medium, e.g. helium, to container 32, 24, thus reducing the working pressure of the refrigerator. Valve 22 is closed when the refrigerator is started so that working medium is prevented from returning to the refrigerator, and is opened when the refrigerator is stopped so that the medium stored in container 24 is returned and the refrigerator operates at high pressure at the beginning of the next working period. In the modification of Fig. 3 (not shown), a compressor is used to circulate a medium to be cooled over the cold head of the refrigerator, and the switch 12 has a first contact in the energizing circuit of valve 16 and a second contact in the energizing circuit of the compressor and the valve 22. At start up, valve 16 is closed, the compressor inoperative and valve 22 open and cooling at maxixum pressure takes place until a first predetermined temperature is reached, when the second contact closes to energize the compressor and close valve 22. The first contact closes, when a lower temperature is achieved, to open valve 16.

A horizontal double-twist spindle especially for use in the cabling-assembly of Specification 915,942 comprises a shaft 19, Fig. 1, axially bored at 34 for the passage of the yarn, and, at the inner end of the bore, a transverse bore 82, Fig. 2, provided with a removable cartridge containing a freely-mounted grooved roller 91 so disposed that a tangent to the roller at the bottom of the groove substantially coincides with the axis of the shaft, and leading from the bore 82, a radial bore 35 for passage of the yarn. The bore 82 is formed in a frusto-conical part 31 of the shaft to which is secured a plate 33 so that a yarn-bore 36 in its hub coincides with bore 35 and a transverse-bore 83, 84 coincides with bore 82. Bore 83, 84 is internally screw-threaded to receive plugs 87, 88 locating the cartridge which consists of a sleeve 100, and two recessed plugs 96, 97 carrying a pin 93 on which the roller 91 is mounted on bearings 94, 95. Sleeve 100 has an aperture and a flap in the region of the groove, the flap closing that part of the groove to which the yarn does not pass. A transverse pin 101 positions the cartridge axially and prevents its rotation. A second plate 48 is mounted by bearings 45, 46 on the shaft; this plate carries housings 51, 76 and supports cage-bars 50 carried at the front of the device by a ring 86. Housing 51 carries a counterweight 52 and housing 76 a brake drum 64 connected to a package sleeve 54 rotatably mounted by bearings 55, 56 on the spindle. The brake-drum 64 is associated with a yarn-feeler 103, Fig. 3, in the cage, which is one arm of a bell-crank on a pivot 104 of which the other arm has three holes 106 to one of which is connected a spring 107, adjustable according to the position of a nut 108 on a screwed-rod 110. The bell-crank is integral with a lug 105 to which is attached one end of a brake-belt 115 having an elastic portion 116. The package-sleeve 54 has a fluted recess 67, in which a grip-ring 68 rolls as the package is donned or doffed, and an extension 70 with three gaps each containing a retaining-spring 73. Guides 79, 80 are carried by one of the bars 50 and a further guide 81 by a pivoted bar 119. The shaft 19 is mounted in bearings 23, 24 and is driven by a pulley 13; when the device is used as a let-off spindle, the yarn passes over the lowermost bar 50, which is rotatably mounted to offset tension-changes as the package unwinds, over a second bar to the feeler, by which the unwinding package is braked to adjust the yarn tension, to a third bar and guides 79, 80, 81 and thence to bore 34 and roller 91 where it receives its first twist; it then travels through bores 35, 36 over rollers 41 and a ring 43 carried by plate 33, between which and an external guide it forms a balloon and is further twisted. Specification 915,943 also is referred to.
