Title: Improvements in or relating to compasses
IPC: G01C17/00
Filed: 1934-07-19
Abstract: 430,126. Bearings. ASKANIA-WERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU, 1, Unruhstrasse, Dessau, Germany. July 19, 1934, No. 21172. Convention date, July 19, 1933. [Class 12 (i)] [See also Group XX] In a compass, the weight of the magnet system 1, 2 is supported by fluid pressure below a movable support 4 the position of which controls the size of the inlet opening to the space 9 below the support. As shown in Fig. 1, the support comprises a skirted piston 4. A magnet-supporting beam 3 is mounted on the piston 4 which is floatingly supported within a cylinder 5 by compressed air admitted by a pipe 6 to an annular chamber 7 communicating with the interior of the cylinder by three or more equally spaced holes 8. The compressed air passes into an annular groove 10 in the piston skirt and through three or more equally spaced holes 11 into the space 9, whence it escapes by slots 15, 16 and vertical bores 13, 14. As the pressure in the cylinder increases, the piston rises and takes up an equilibrium position in which the lower edge of the groove 10 more or less obturates the holes 8. The equiangular arrangement of the holes 8 ensures the piston being cushioned on all sides by the air pressure so that no frictional contacts take place. Steadying bearings in the form of stone bearings 21, 22 contacting a polished resilient steel spindle are provided. Vertical oscillations are damped by a dashpot device 18, 19. The piston skirt is recessed opposite the slots 15, 16 along half its periphery, and the control edges 27, 28, Fig. 4, so formed are utilized to cut off one or other of the outlets 15, 16. This arrangement is utilized when the escaping air pressure controls the relay of an automatic steering device. In this case the compass may be set for a given course by rotating the cylinder 5 by means of the worm gearing 29, 30. The escaping air may also be used to control a remote steering indicator, or a stabilizing or turnindicator gyroscope.

Abstract: 1352609 Electron microscope display NIHON DENSHI KK 19 April 1971 [7 Feb 1970 (2)] 21238/71 Heading H4F An image signal produced by an electron microscope 1, is displayed (on a CRT 8 for example) as a contour-type display, with each contour line corresponding to the image signal being equal to one of a plurality of reference levels. The microscope 1, Fig. 1 and CRT 8 are synchronously controlled by scanning circuit 2 and the image signal is amplified 3 and compared with a plurality of reference voltages 6a, 6b ... 6n in comparators 5a, 5b ... 5n which generate voltage pulses when the input signal is equal to the respective reference voltage, these voltage pulses being fed to the CRT display via a brightness control circuit 7 which ensures that all the pulses are of uniform level. Alternatively (a) two brightness control circuits may be employed (Fig. 3, not shown) so that every third contour line is at a different brightness, (b) each contour line may be selectively displayed (Fig. 5, not shown), (c) the contour lines may be displayed superimposed upon a conventional display of the image signal (Fig. 6, not shown), (d) the contour lines and a conventional display of the image may be displayed on separate CRT's or alternately on a single CRT (Figs. 7 and 8, not shown). In an alternative arrangement, Fig. 9, a selector circuit 13 selects a horizontal sweep signal from scanning circuit 2 and applies it to gates 11 and 12 which respectively pass a constant level signal from generator 10 via brightness control 14 to the CRT display 8, and one line of the image signal from amplifier 3 via amplifier 15 to an oscilloscope 16. Thus on CRT display 8 the contour line signal (and/or the image signal when the display arrangement is as described in the embodiments of Figs. 6-8) is displayed with a uniform brightness line superimposed thereon, and on oscilloscope 16 the distribution of the brightness modulation of the selected line of the image signal is displayed in two dimensional form. The selected line may be rotated around the image by including a scan direction modify circuit (19, Fig. 11, not shown) between the scanning circuit 2 and the microscope 1 and CRT 8. Alternatively by including the scan direction modify circuit (19, Fig. 13, not shown) between the scanning circuit 2 and the microscope 1 only the displayed image may be rotated about the selected scan line.

Filed: 1949-08-17
Abstract: 659,679. Time switches. LANDIS & GYR SOC. ANON. Aug. 17, 1949, No. 21439. Convention date, Aug. 19, 1948. [Class 38(v)] Energization of an electromagnet 1 causes a wheel 36 driven by a synchronous motor 3 to be coupled to a wheel 37 which thereupon drives a shaft 6 which through differential gearing 19, 20, 21 drives a preset arm 27 so that at a predetermined time the arm engages a pin 28 and releases a switch member 5 which, in addition to making a signalling or other circuit, breaks the circuit of the electromagnet 1; this causes the wheels 36, 37 to revert to their uncoupled state and the shaft 6 rotates backwards under the influence of a spring 8 which has been strained by the forward movement causing the arm 27 to move away from the pin 28, but this is held latched by the member 5, 32, engaging behind a projection 31 till just as the starting position of the shaft 6 is being reached a pin 13 on the shaft operates an arm 15 which by means of a pin 16 lifts the switch back into its original position. At this moment also a pin 44 on the shaft 6 moves an arm 46 away from under the end 47 of a lever 39 so that the recoupling of the wheels 36, 37, which now tends to occur owing to the re-energization of the magnet 1, is only now possible. Time setting is effected by an arm 25 which through gearing 24, 23 rotates the sun wheel 20 and thence the shaft 26 carrying the arm 27.
