Title: Improvements in or relating to apparatus for measuring or indicating the roughnesses or undulations of a surface
IPC: G01B5/28
Filed: 1943-08-17
Abstract: 579,003. Measuring surface-roughness. KAPELLA, Ltd., and REASON, R. E. Aug. 17, 1943, No. 13365. [Class 106 (ii)] In apparatus for measuring the surface-roughness of a body of circular section, a pick-up head carrying a stylus is caused to traverse a circular path, means responsive to relative movement between head and the stylus operating an indicating or recording instrument. A bar D, Fig. 1, is caused by known means to reciprocate in a casing A, the bar being moved for setting purposes by a cam A4. A supporting member E detachably fixed to the bar carries the pickup head B by means of two spring ligaments E2, E3 and a plate F. The stylus B1 engaging the test body C3 operates a known electromagnetic device controlling an indicator or recorder. A screw F3 in the plate F bears on a two-part radius bar G, G1, the lower end of the bar engaging a thrust block H, H1 adjustable in vertical slides H2 on a bracket H3 carried on the casing A. The bracket H3 is steadied by a foot H7. As the bar D is moved to the left, the radius bar G, G1 rocks anticlockwise and, through the ligaments E2, E3, causes the stylus to follow a convex path. The stylus can be moved in a concave path by arranging for the radius bar to' bear on the top of the screw F3. In a modification, the pick-up head is adjustable horizontally on the plate F. In a further modification, Fig. 6, the pick-up head B is attached to the supporting member E by a single spring ligament K and is pressed into contact with the radius bar G, G1 by a spring K1. Specifications. 539,273, 556,975, [Group XXXVIII], 567,918 and 579,002 are referred to.

In one arrangement, Fig. 1, the saturable reactor 7 is provided with assisting control windings 5 and 4 energized respectively according to the load current and voltage. An opposing winding 6 energized by a current derived across the carbon resistor of a voltage regulator 8 included in the load circuit is also provided in order to reduce the charging current as the load voltage tends to increase. An isolating switch 11 in the load circuit when opened short circuits a resistance 10 included in the circuit of winding 4, thereby increasing the charging current. A switch 9 also included in circuit with winding 4 is opened by an ampere-hour meter when the battery is fully charged. In another arrangement (Fig. 2, not shown), two parallel connected reactors are provided respectively with windings 4 only and 5 and 6. In a further arrangement (Fig. 3, not shown), two rectifiers are parallel connected on the output side, each associated with a transformer and reactor, one of the latter having control windings 5 and 6 only. The circuit containing the non-saturable reactor is controlled by a relay under the control of switch 9. In a still further arrangement, Fig. 4, the reactor 40 is saturated over rectifiers 21, 31 by auxiliary reactors 20, 30 connected across the output terminals of transformer 3. Each auxiliary reactor is provided with internal self-magnetization and control windings 25, 24 respectively are energized in accordance with the load current whilst each is provided with a further control winding 26, 34 connected respectively across the output of rectifier 1 and the resistor of regulator 8. Winding 24 providing fewer ampere turns than winding 25 is opposing to reduce the charging current as the load increases so as to maintain the loading on the rectifier substantially constant. When the rectifier providing the charging current is connected to a separate alternator such as an axle driven generator, the rectifier may be included in the exciting circuit of the generator to provide the generator excitation.

Abstract: 812,953. Automatic current control systems. BRITISH THOMSON-HOUSTON CO. Ltd. June 27, 1956 [May 12, 1955], No. 13773/55. Class 38 (4). [Also in Group XL (c)] The part of the beam current that passes between the apertured accelerating anode and the screen of an electrostatically focused cathoderay tube is maintained constant by automatically controlling the control grid bias. The system is particularly applied to multiple tube radar displays. The potential of the graphite coating G of the tube is used as a measure of the beam current and is applied to the control grid of a transitron oscillator VI so that as the beam current increases the amplitude of oscillation decreases. The output of the oscillator is rectified at D1, D2 to provide the bias for the grid of the cathode-ray tube and is in the sense to reduce the beam current as the bias decreases. For a multi-tube display, Fig. 1 (not shown), each tube is provided with its own bias oscillator, and individual brightness control, e.g. RV1, these controls being tapped in parallel off a master control RVM whereby the brightness of all the tubes may be adjusted simultaneously.
