Title: Means for indicating load eccentricities in presses
IPC: B30B15/00
Filed: 1954-07-13
Abstract: 755,896. Electric indicating systems. LOEWY CONSTRUCTION CO., Inc. July 13, 1954 [July 15, 1953], No. 20448/54. Class 40(1) Eccentricity of the load in a forging or other press is determined by measuring the differential strain imposed by the load on frame members located on opposite sides of the main axis of the press. and indicated, e.g. on a cathode ray tube, or audibly. The press may be controlled automatically by the eccentricity value. Fig. 1 shows a "pull-down" forging press in_ which a movable platen 12 is pulled down towards the fixed lower platen 10 by hydraulic rams 32 acting through a lower cross-head 31, columns 30 and upper cross-head 14. If the force applied to the work between the supports 11-15 is eccentric to the press central vertical axis, Fig. 3, bending movement is applied to the column 30. in addition to the normal linear strain. Strain gauges A-B-C-D located at the outside corners of the columns are connected to measure the strains (A-B)+(D-C) and (A-D)+(B-C). The differential connections cancel out the effect of the linear strain and the. two measurements correspond to the bending movement about the minor and major axes, respectively. The gauge outputs are fed through respective transformers A-D, Fig. 4, having double wound secondaries so connected to transformer primary coils A3-D3, A4-D4 as to produce in the secondaries E, F voltages proportional to (A-D) +(B-C) and (A-B)+(D-C). These outputs are applied to the quadrature deflecting plates of a cathode ray tube whereby the spot O is deflected in accordance with the load eccentricity. A mask may be applied over the "safe" area of the tube screen so that appearance of the spot outside this area warns that the bending movement has reached a dangerous value. A recorder may be operated instead of the indicator.

Abstract: 637,258. Rotary tool heads. GIDDINGS & LEWIS MACHINE TOOL CO. July 30, 1947, No. 20628. Convention date, April 24, 1941. [Class 83 (iii)] [Also in Group XXIV] The rotary tool head of the horizontal boring, drilling and milling machine described in Specification 531,759, is modified by arranging the housing 26 for the head so that it is axially adjustable on the power-driven spindle 23, mounting the annular gear 39 for effecting feed of the tool slide 30 in freelyrotatable manner on the housing, and providing means for releasably retaining the gear against rotation. The housing 26 is fixed to the spindle 23 by an adaptor 33 which is bolted to the housing and is adapted to be connected in adjusted position on the spindle by a key 34 and setscrew 38. The annular gear 39 is fixed to the hub of a hand-wheel 40 freely rotatable on the adaptor and adapted to be held against rotation by a chain. The gear 39 meshes with a gear 43 rotatably mounted in the housing 26 and the drive therefrom to a screw 56 for operating the tool slide 30 includes a change-speed unit 46 and clutch mechanism 52 for controlling the direction of feed of the tool slide. The speedchange unit provides six speed settings under the control of a manually-operated rack and pinion drive 84, 85, and reversing clutch mechanism 50 is automatically operated from this drive to ensure that the drive to the mechanism 52 is always in the same direction despite the fact that alternate speed settings of the speed-change unit causes its output shaft to drive in opposite directions. In addition to the power feed of the tool slide when the hand wheel 40 is held stationary and the spindle 23 rotated, the slide may be traversed manually either by turning the hand wheel 40 when the spindle is at rest or by a hand crank inserted into a socket 106 carrying the bevel gear 103 of the mechanism 52; a micrometer dial 107 is mounted at the outer end of the shaft to provide a continuous indication of slide-feed both during power and manual drive.

Title: Gyroscopic compass
IPC: G01C19/38
Filed: 1920-07-10
Abstract: 148,967. Ges. f³r Nautische Instrumente. March 27, 1919, [Convention date]. Gyroscopic compasses.-Relates to damping- means for compasses of the floating type having a follow-up device. The gyroscope 1 is carried by a float 3 in a vessel 4 containing mercury and is centred by an upper pin 9 secured to the vessel 4 and passing through an eye 11 in a cup 10 formed in the floating system, and by a lower pin 12, carried by the gyro-casing and passing into a. slot 12<1> formed by cheeks 13, 14 carried by an arm 15 secured to the vessel 4. The vessel 4 is turned to follow the movements of the gyro-axis 2 by a motor 16 operated by contacts 6, 7 carried respectively by a disk 5 secured to the floating system, and by the vessel 4. The length of the slot 12<1> consequently remains parallel to the axis 2. According to the invention, damping is effected by causing the cheek 13 which lies to the west of the pin 12 to press constantly against the pin. This pressure is obtained either by loading the floating system on the east side, as by a weight 26 secured to the disk 5, or by loading the slot on the west side either directly or indirectly, e.g. by loading the vessel 4. Specifications 10382/08 and 11028/11 are referred to.

Abstract: 1,246,907. Light modulators. EIDOPHOR A.G. 24 April, 1969 [24 April. 1968], No. 21092/69. Heading H4F. In light modulating apparatus utilizing a medium which is deformed by a scanning electron beam, the conventional bar and slit Schlieren optical system is replaced by a plurality of mirrors arranged in a checkerboard pattern and so mounted that as seen from the illuminating light source they appear to be contiguous, whilst as seen from the deformable medium they appear to be spaced apart, the spaces between the mirrors having substantially the same area as the surface area of the mirrors. Thus the illuminating light beam is split into individual contiguous rays by the mirrors and reflected on to the deformable medium. As seen from the deformable medium the mirrors in every other row and in the same column appear to be spaced apart so that when the medium is in the undeformed state light from the source is reflected by the medium (preferably backed by a concave mirror) and mirrors back to the source, whilst deformation of the medium deviates the light reflected therefrom to pass through the spaces between the mirrors. The mirrors have at least one non-reflecting surface.
