Abstract: 1505519 Gyroscopic apparatus ANSCHUTZ & CO GmbH 3 June 1975 [5 June 1974] 23981/75 Heading G1C Gyroscopic apparatus comprises a hollow sphere 10 containing at least one driven gyroscope, and a vessel 12 at least partially surrounding the sphere 10 so as to define a gap which varies in width from a liquid inlet 22 towards a liquid outlet 28, there being further provided a pump 14 for circulating the liquid through the gap so as to floatingly support the sphere 10. The gap width s at any given point between inlet 22 and a discontinuity 30 or 30' in the gap width being defined by the where s o  is the gap width at the inlet 22, d the diameter of a circle formed by the intersection of a horizontal plane passing through the point and the sphere, d o  the diameter of a similar circle which corresponds to the position of the inlet 22 and K is substantially constant being within the range 0À9 to 1À3. The variation in the gap width from the inlet is such that the liquid has a laminar flow through the gap with suitable pump operation, and displacement of the sphere due to gravity or acceleration produces a force within the fluid which acts to counteract the displacement. As described, there are provided electrically conductive portions of the facing surfaces of the vessel 12 and sphere 10, the liquid being an electrolyte so as to allow electrical energization of a motor driving the or each gyroscope, any resultant heat generation being dissipated by a container 20 which also defines, with vessel 12 a liquid return path from outlet 28 to the pump 14. The inlet 22 and outlet 28 may each comprise a plurality of ports lying on a circle. Various gap configurations are shown, e.g. as shown in the left and right hand embodiments of Fig. 1. The width s in the bearing zone i.e. the zone beneath 30 or 30' is 0À013- 0À0075 of the diameter of the sphere 10, and the weight of the sphere plus contents is 1À003-1À010% of the weight of the liquid displaced by the sphere 10. The internal surface of the vessel 12 is preferably in the shape of a surface of revolution. Where large accelerations are likely to be experienced, sensing means may be mounted on the vessel 12 which is responsive to relative displacement of the sphere 10. Control means, e.g. a valve or means to vary the pump 14 speed is then provided to vary the liquid velocity so as to maintain the sphere 10 at a constant position relative to the vessel 12. Also described is a gyrocompass which is substantially identical to that described with reference to Fig. 13 (not shown), of Specification 1117848 but differing therefrom by the shape of the internal surface of the vessel 12.

Abstract: 389,104. Protective cut-out arrangements. RHEINISCH-WESTF€LISCHES ELEKTRIZITATS - WERK AKT. - GES., Essen, Germany. Aug. 31, 1931, No. 24444. Convention date, Aug. 29, 19,30. Addition to 309,182, [Class 38 (v), Electric switches &c.]. [Class 38 (v).] For carrying into effect the protective arrangement described in the parent Specification the relay employed has a coil with a plurality of windings and an armature which is movably mounted between the poles of a permanent magnet and which is moved to release a switch as soon as the sum of the magnetic effects of the windings of the coil differs from zero owing to one of the current-carrying conductors being touched. As shown in Fig. 1, coils c, d in the circuits of the conductors e, f are wound in opposition on an H-armature b pivotally suspended between the poles of a permanent magnet a. Normally the effects of the coils neutralize each other and the armature is retained as shown in the central position with an insulated arm n resting against a stop g, but when the currents in the conductors e, f are unequal the resultant magnetic force of the coils b, c magnetize the core so that it swings and engages by a projection i a tripping lever k of a spring-controlled switch in the circuit e; f. If used on A.C. and the force on the armature at the moment is in a direction pressing the arm n against the stop g, tripping is not initiated until the succeeding half-cycle. More than one pair of opposing coils may be mounted on the armature b. In a modified arrangement, Fig. 3, for a three-phase circuit e, f, t a single coil o fed through the secondary p of a summation transformer v is mounted without a core between auxiliary polepieces of a permanent magnet a. An armature b<2> attached to an arm extending from the coil O is mounted between the main polepieces N, S so that as soon as the tripping movement is initiated the armature b<2> is attracted strongly to the polepiece N. A further form of relay (Fig. 2, not shown) may, alternatively, be employed, of the type comprising a movable magnetic core disposed within a stationery coil consisting of opposing windings in series with the current-carrying conductors, the core extending between the poles of a permanent magnet and being arranged to operate tripping mechanism in the manner previously described.

Title: Improvements in apparatus for observing or measuring changes in inclination of a support or for levelling the line of sight of optical instruments by means of a pendulum
Inventor: HOFMANN OTTO
IPC: G02B27/64
Filed: 1956-08-09
Abstract: 836,717. Clinometers, optical systems. ZEISS JENA C. VEB. Aug. 9, 1956, No. 24477/56. Classes 97(1) and 97(2) Weights are hung between a suspender or inverted pendulum and a tiltable member so that when the member is tilted the tension in the strings supporting the weights are varied to make the pendulum take up a new non-vertical position of equilibrium. As shown, the tensions in strings 4a, 4b and 5a, 5b due to weights 3a, 3b maintain pendulum 1 in an inverted position of equilibrium and on tilting the member 2 the pendulum takes up a new position of equilibrium. For small angles of inclination cc and #, there is a linear relationship between # and #. The inverted pendulum arrangement may be used in a pendulum level (Figs. 8, not shown, and 9) and in a sighting telescope to maintain the line of sight horizontal (Figs. 12, not shown, and 10). In one form of inverted pendulum the bob is a hollow cylinder 15, Figs. 5 and 7, containing a fixed damping piston 16 and is supported on arms 7 articulated to a fixed frame 6 by crossed band springs 8 or, alternatively, by a torsion wire (not shown). Weights 9, 10 hang between arms extending from the bob and from frame 6. The space 17 may be occupied by an optical component fixed to the pendulum such as, presumably, the two mirror 24, 25 (Fig. 9). Cross-wires 20 are imaged in the focal plane 27 of eyepiece 28 and, on tilting the casing 18, the image is displaced as the mirror carrying member 23 turns about axis Y-Y relatively to the casing and mirror 26. In Fig. 10, mirror 34 is movable to ensure that a horizontal ray in. cident on mirror 32 forms an image in the centre of graticle 31<SP>1</SP> irrespective of the inclination of the telescope casing. Alternatively the movable mirror may be arranged between the objective 30 and eyepiece 31 (Fig. 12, not shown). A suspended pendulum arrangement (Fig. 2, not shown) is used in a further example of a sighting telescope (Fig. 11, not shown).
