Title: Apparatus for supporting the rotor of a vertical gyroscope when the gyroscope is not in use
IPC: G01C19/44
Filed: 1920-07-09
Abstract: 148,309. Krupp Akt.-Ges., F. Nov. 18, 1915, [Convention date]. Gyroscopic apparatus is provided with means for supporting the rotor when not in use so as to take the load off the bearings. The rotor A is carried by the vertical shaft C within a casing B which is mounted in gimbals in an outer casing E. At its lower end the casing B has a cylindrical extension around which is a sleeve F capable of movement against a spring G. The sleeve F has four lugs f<1> passing through apertures in the casing B and faced with leather &c. f<2>. The sleeve is prevented from moving downwards by stops b<2> secured to the casing, and is held in its normal position by right-angled pawls H<2> pivoted to the sleeve and engaging with shoulders b<1>. The operating-device carried by the casing E comprises a plunger J having a collar i<1> and surrounded by a sleeve K, within which is a sleeve Q abutting against the collar i' and capable of sliding against a spring P. The sleeve K has rack teeth k<1> gearing with a pinion M operable by a lever M<1>. To stop and support the rotor A the lever M<1> is turned downwards, causing the plunger J to enter the bore b<3> and the sleeve Q to turn the pawls H<2> and release the sleeve F, which is then pushed upwards by the sleeve K. The surfaces f<2> are thus pressed against the rotor and bring it to rest. When the lever M<1> is pressed into its lowermost position, the force exerted by the spring P is sufficient to support the whole weight of the rotor and thus relieve the bearings of pressure.

The fixing treatment may be applied for periods varying from one to ten seconds. Subsequent treatment may include developing the colour e.g. treating with 2 per cent sulphuric acid for ten minutes at 60‹C., rinsing and drying and doubling yarns of opposing twist.

Abstract: <PICT:0443759/IV/1> A moulded reflector comprising a single reflecting unit, for example an auto-collimating unit of tetrahedral form or a series of such units as shown, is made from a material, such as a mouldable artificial resin, having the property of finally setting and conforming accurately to the reflector-forming surfaces of a matrix without sinking or becoming fragile.  The material may be a thermosetting resin such as urea-formaldehyde, a thermo-plastic artificial resin such as styrol or polymerized vinyl alcohol, chloride or acetate.  The material and the mould are heated to the required pressing temperature and pressure is then applied and continued until the material finally sets and accurately conforms to the matrix.  In the case of a thermo-setting resin the material is removed from the mould without cooling to room temperature, and in the case of resins of the thermo-plastic type the material is cooled to room temperature before pressure is removed. Specification 269,760, [Class 56], is referred to.

Class 98(1) An X-ray apparatus having means for radioscopy and/or radiography of dorsal regions of the human body and/or organs of the body located at or near the dorsal regions without varying the position of the body throughout the whole operation of radioscopy and/or radiography, comprises mechanical support means for a patient's body, said means being shaped so as to give the longitudinal axis of an extended body an arcuately shaped form which is concave in relation to the focal spot of an X-ray tube with the patient facing the focal spot of the tube, thereby substantially cancelling out the curvature of the lumbar vertebrae, and means for arranging a fluorescent screen and/or a radiographic film in a position parallel or approximately parallel to and near the place of the dorsal region. As shown the support comprises a frame of tubular steel carrying a canvas sheet 36, and having a footrest 35 at one end. The support is releasably attached to the table 1 of a conventional X-ray apparatus by means of bars 2, 3 having spring claws gripping the edges of the table. Member 2 carries a deformable parallelogram linkage 11 to which a support 21 fixed to the frame is pivoted. A handle 19 engages nuts at opposite pivot points of linkage 11 so that the frame may be raised and lowered. Memberhas an extension 23 to which a support 22 fixed to the frame is pivoted. Support 22 carries a sector 24 with holes engaged by a slidable plunger mounted on extension 23 and operated through a Bowden cable 27 by a handle 28 mounted on the frame. By this means the frame can be tilted with respect to table 1. Pads 54 are carried on arms 49 releasably clamped to the frame, and can be adjusted to bear, through rubber sheets covering apertures 55, 56 in the sheet 36, against the patient's body to compress certain organs. In use, the table 1 is brought to a vertical position, handle 19 is turned to bring the support close to the table, and the support is rotated. The patient then steps on footrest 35 and leans on 'the support, which is then rotated so that the patient is brought to a position facing the table between the table and the fluorescent screen and cassette carrier (not shown). Table 1 is then brought to a horizontal position, and handle 19 turned to raise the support to the required height. The patient is then face down with his body bowed upwards, the curvature of the lumbar vertebrae being substantially cancelled out. In this position a fluorescent screen or film cassette can be brought close to the kidneys, and radioscopy or radiography of the kidney region can readily be carried out by means of an X-ray tube below the table.
