Title: Compass theodolite
IPC: G01C1/02
Filed: 1933-07-29
Abstract: 402,027. Theodolites. VERKAUFS-AKT.- GES. H. WILDS GEODATISCHE INSTRUMENTE, Heerbrugg, Switzerland. July 29, 1933, No. 21400. Convention date, Aug. 5, 1932. [Class 97 (ii).] The azimuth reading of a theodolite is obtained by reflecting into a single eyepiece diametrically opposite portions of the scale on a pivoted, graduated disc, which is fixed to a magnet and may be lifted from its pivot when desired. In the form shown the telescope 1 rotates about a horizontal axis 2 in a frame 3 rotatable about the vertical axis 4 on a base 5, a fine adjustment device 7 and clamp 8 being provided. Part of the frame 3 forms a casing 9 in which a graduated disc 10 fixed to a magnet 14 pivots on a pin 12 supported in the base 5 by the pillar 15 and foot plate 16. The disc 10 may be clamped against the inturned edge 17<1> of a basket 17, fitted to the base 5, by a lifting plate 19 which is mounted to slide up and down the pillar 15 and may be raised to the clamping position against the action of the spring 26 by a bell crank lever 23 operated by a screw 22. Diametrically opposite portions of the scale on the disc 10 are illuminated through windows 27 and 28 and reflected by prisms 29, 31 and 30, 32 respectively into prism 33 and eyepiece 34. The graduation marks of the two images may be brought into coincidence by rotation of a parallel sided glass plate 35 which is arranged between the prisms 29, 30 and 31, 32 and fixed to a pointer 39 moving over a scale 40. The latter gives the correction to be applied to the mean of the two graduations brought into coincidence. The eyepiece 34 may be arranged in the plane of revolution of the telescope 1 and may be tiltable together with the prism 33 about a horizontal axis.

Title: Shadow mask colour cathode ray tube and method
IPC: H01J29/07
Filed: 1965-05-20
Abstract: 1,089,154. Colour television tubes. RADIO CORPORATION OF AMERICA. May 20, 1965 [June 12, 1964], No. 21412/65. Heading HID. The rectangular, domed shadow mask electrode of a colour television tube is formed by a multi-apertured sheet-metal masking member mounted across a rectangular frame, the sides of the frame being formed of a member which is of substantially uniform cross-section along its length, whereby to minimize distortion produced by temperature fluctuations. The masking member 30 is mounted around its edge on the frame 32, each side of which is formed by a member having axial and peripheral flanges 50 and 48, the sides being bowed both outwardly away from the tube axis (Fig. 2, not shown), and towards the faceplate 20, as shown, such that their curvature conforms to that of the faceplate. The frame is of thicker material than that of the masking member, to act as a heat sink, and the peripheral flange 48 is preferably formed, at an angle # to the axial flange, such that it lies parallel to the faceplate, whereby a smaller peripheral flange width suffices to shield the axial flange 50 from the incident electron beam. The frame is manufactured from L- angle stock by bending into a planar rectangular shape having outwardly bowed sides, welding the two ends together, and pressing on to a spherical surface.

Filed: 1961-06-14
Abstract: 939,622. Speedometers. L. BOLKOW, [trading as BOLKOW ENTWICKLUNGEN KOMM.-GES.]. June 14, 1961 [June 28, 1960], No. 21480/61. Class 106 (3). [Also in Group XX] For measuring, or regulating, the speed of a slowly moving member such as a machine tool, the translational motion of a member 1 fixed to the tool is converted to rotary motion by a friction wheel 2 to pivot the outer Cardan frame 4 of a gyro unit about the axis 3 (a rotational movement to be measured may, of course, be applied directly), thus causing precession, about the axis of shaft 5, of the inner frame 6 supporting the gyro rotor (a reversible A.C. motor with an external rotor). The precessional deflection is opposed by a spring 27 or 28, depending on the direction of deflection, and in equilibrium, a conducting arm 15, rotating with the shaft 5 to scan a potentiometer 13, 14 will establish a definite voltage applied, via some of the slip rings 10, to an indicating instrument 12, which may be calibrated, for example, in mm./min., and/or to an amplifier 19, coupled to a servomotor 20, and responsive to variations of speed of the tool to regulate the speed and maintain it constant. A separate stable voltage source 11 is used for the potentiometer 13-14. A further potentiometer 17, coupled to the input of the servo-amplifier, can be manually adjusted to vary the desired feed-speed of the tool. The switches 22 allow rotation of the gyrostat in either direction at two different speeds. The springs 27, 28 opposing the precession may be replaced by hydraulic, pneumatic or magnetic devices.

[Class 81 (ii)] [See also Group XXXVI] In apparatus for recording an electrocardiogram by taking three voltage readings between any two of the points right arm R, left arm L and left foot F simultaneously, two of the readings are separately amplified and the third reading is obtained from the other two as a difference of the voltages or currents in the output circuits of the two amplifiers. Fig. 2 shows an arrangement in which voltageoperated oscillographs B1, B2 and B3 are used. The anode resistances R1 and R2 of the two amplifiers are in the form of a potentiometer by which the gain of the amplifiers is balanced. The adjustment can be checked by applying a voltage at point S : on correct adjustment the oscillograph B3 gives no reading. In the arrangement shown in Fig. 3, current recording oscillographs O1, 2 and DS are used. The sensitivities of the two branches of the differential oscillograph DS are adjusted inversely to the gains of the amplifiers by a potentiometer having branches p1 and p2. A calibration voltage applied at point S should not affect the differential oscillograph.
