Abstract: 1515372 Master-slave control system COMMISSARIAT A L'ENERGIE ATOMIQUE 11 June 1975 [19 June 1974] 25113/75 Heading G3N A control system has a master assembly a and a slave assembly b with effort return. Master lever 1a rotates about pivotal shaft 2a which is driven by motor 3a via gears 4a and the slave assembly is similar, the two being separated by a barrier 6. Respective detectors 5a, 5b, e.g. optical or magnetic, transmit position signals to summer 8 which gives the instantaneous position difference between levers 1a, 1b. This difference is passed via preamplifiers 10a, 10b and power amplifiers 11a, 11b to control the motors and reduce the difference to zero. If lever 1b encounters resistance, and lever 1a is displaced, motor 3b supplies a torque to overcome the resistance, and motor 3a supplies an equal torque to motor 3a and thus a resistance to lever 1a. This also operates from master to slave. Summer 8 can also receive auxiliary pulses via line 9 to allow shift of lever 1b without movement of lever 1a. In another embodiment, Fig. 2 (not shown) the motion detectors 5a, Sb feed respective counters whose contents are sampled using mutliplex techniques on a single connecting line between the master and slave assemblies, difference in velocity and position being measured. In a further embodiment, Fig. 3 (not shown) acceleration differences are also used and both these embodiments can be controlled by a mini or micro computer. In another embodiment, Fig. 4 (not shown) the signals pass through D/A converters before summation and an analog control loop can be used. The slave assembly is in a deleterious medium so most of the circuit elements are adjacent the master assembly.

Abstract: 518,554. Electric endosmose; electrodeposition of oxides. BARLOW, R., and CLAYTON, W. Aug. 26, 1938, No. 25184. [Class 41] A metal surface, particularly the interior or interior and exterior surface of a food container is coated with a naturally occurring hydrophilic colloid of animal or vegetable origin by electrodeposition from an aqueous solution containing sodium aluminate. The colloidal substance may be unmodified or soluble starch, egg albumin, pectin, gum arabic, gum tragacanth, gum ghetto and gelatin or those contained in milk. An alkaline solution of the colloid containing sodium aluminate with or without sodium silicate is employed; alumina or silica is simultaneously deposited this promoting adherence of the colloid. Such a solution may be brought to the verge of precipitation by addition of sodium bicarbonate; this reduces the initial lag before deposition sets in. Alternatively sodium bicarbonate may be added to a solution of the aluminate with or without silicate and the resulting precipitate filtered off before addition of the solution to the colloidal material such as starch paste. Specifications 455,810, 479,681, and 492,160 are referred to.
