Title: Improvements in methods and apparatus for microscopically examining the profiles of surfaces
IPC: G01B11/25
Filed: 1933-03-06
Abstract: 395,649. Gauging-apparatus. SCHMALTZ, G., 79, Frankfurterstrasse, Offenbach-on-Main, Germany. March 6, 1933, No. 6701. Convention date, March 10, 1932. [Class 106 (ii).] A surface is examined or tested by imaging a knife edge or a slit on the surface and examining the luminous boundary line thus produced by a microscope the axis of which is inclined to that of the light pencil incident on the surface. If the part of the surface under examination is truly plane the boundary line is straight, and any deviation from a plane surface is indicated by waviness of the line. In the form of apparatus shown, the means for illuminating the surface is carried by a bracket a secured to the microscope tube b so that the axis of the illuminating device is at right-angles to that of the microscope. The illuminating means comprises a light source d, a converging lens e, a slit diaphragm f, and an imaging system g which forms on the surface h to be examined an image at the focus of the microscope objective. The surface h is slightly inclined to the axis of the microscope. Different parts of the surface may be examined by moving the microscope tube and illuminating means up and down. A number of slits may be used so that several luminous lines are obtained for successive examination. There may also be projected on the surface a number of plane pencils crossing each other at right-angles so that two intersecting series of lines are obtained. The examination may be effected microphotographically instead of by viewing. In a modified form of apparatus the axis of the illuminating-device is parallel to that of the microscope tube, the surface to be examined being placed below the illuminating-device and a mirror being arranged below the microscope objective to receive light from the surface and direct it into the objective.

Abstract: 249,124. Soc. Anon. A. Saurer. March 10. 1925, [Convention date]. Letting-off warps ; warps, tensioning ; warp beams.-The warp passes from the beam 2 over a back rest 3 supported by arms 9, 10 connected by bars 20, 21 and cranks 18, 19 to a shaft 17 furnished with levers acted upon by springs 26, 27. The arms 9, 10 are mounted on stud shafts 7, 8 carrying the warp beam, which can be driven by a member 16 on a worm wheel 15 geared to a worm 14 on a shaft 11 carried by the arm 9, so that the warp beam participates in the oscillating motion of the warp beam. A continuously-driven friction disc 28 is situated opposite a friction disc 13 on the shaft 11, but normally does not drive it. When, however, the warp is used up and the arms 9, 10 move to the right, the disc 13 contacts with the disc 28 and the warp beam is rotatable and continues to rotate until more warp is delivered than is required. When this occurs, the back rest 3 and arms 9. 10 move to the left under the action of the springs 26, 27, and the rotation of the warp beam is stopped until the excess warp is used up.

Abstract: 1513562 Touch responsive control of receivers; analogue-to-digital conversion FIDELITY RADIO Ltd 10 Feb 1976 [19 Feb 1975] 7094/75 Headings H3Q and H3H [Also in Division H1] Electrical apparatus e.g. for control of radio receivers or lighting or power circuits has an elongate input control 2, 3 providing a continuously variable output signal which is dependent on the position of an operator's finger along the control and a digital store 10 which stores information representing the output signal and the stored information is up-dated when sensing means senses the presence of the finger on the input control. By touching a resistance strip 2 and conductor strip 3, each of conductive ink printed on a panel (1, Fig. 2, not shown) of a radio receiver (1A), a selected voltage from 3 is applied via an amplifier 5 to cause a counter 10 to count up or down until the output voltage 9 from a D/A converter 11 equals an output of a signal processor 6 as determined by comparator 8. The counter 10 is driven from a pulse generator 12 and when the finger is removed from 2, 3 the output from the amplifier falls to a value which operates a switching device 13 which lowers the output of amplifier 5 further and de-activates generator 12. The output 9 is used to control the volume of the receiver. The output 9' is used for control of the tuning and can be set by switching 7 to the other position and touching 2, 3 so as to control counter 10<SP>1</SP> and D/A converter 11 similarly to before. Both strips 2, 3 could be resistive. They could be arranged in a spiral and can be printed on curved surfaces. The strips 2, 3 could vary in width or by printing several layers of conductive ink over one another could vary in thickness to give non-linear characteristics. The strips could be supplied with A.C. Two resistive strips can be connected across sources of potential of different values and two other strips are then connected to a differential amplifier so that any common A.C. components of the sources of potential are disregarded.
