Title: Method of Forming an Array of Channels for Electron Multipliers.
IPC: H01J43/24
Filed: 1967-08-09
Abstract: 1,158,353. Glass manufacture. BENDIX CORP. 9 Aug., 1967 [16 Aug., 1966], No. 36527/67. Heading C1M. [Also in Division H1] To form an array of channels for electron multipliers, a core member such as a wire of metal, plastics or glass is coated with a glass containing reducible metal oxides; a plurality of the coated wires are assembled to form an array and heated to fuse the glass coatings; the wires are removed respectively by etching, burning out or boiling in deionized water to form a plurality of channel openings in the array and the array is treated in a reducing atmosphere to obtain a secondary electron emissive resistive coating on the interior surfaces of the channels. The wires may be coated by drawing a glass tube over the wire or, as disclosed, by passing through a slurry of glass particles which are then dried and fired. Fusing of the array is preferably under pressure to ensure the absence of voids. The glass coating may be bonded together either by an epoxy cement or by waterglass. A water soluble glass for the core is given as B 2 O 3  40-50; Na 2 O 17-20; and SiO 2  34-40; and the main glass for coating as PbO 61; SiO 2  32 and BaCO 3  7, all in weight percentages. Part of the PbO reduces to Pb to give the required interior resistive coating.

Abstract: 944,720. Fluid-pressure servomotor control systems; automatic speed control systems. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI, ACEC. Nov. 9,1960 [Nov. 13, 1959], No. 38483/60. Headings G3P and G3R. [Also in Division F1] In a power unit comprising one or more electric motors supplied by a generator driven by an engine, the field currents of the generator and motor are controlled by means responsive to the difference between the actual engine speed and the desired speed for any setting of the fuel control member. An accelerator pedal 1 actuates through a hydraulic system 2 on a spring loaded piston 3 which operates a fuel control lever 6 having a cam profile calculated to produce a desired engine speed for any position of the lever. The piston rod is resiliently connected to a servo valve 12 by a spring 8, the valve being operated by a diaphragm 14 actuated by the suction at the inlet of the generator cooling fan which is a measure of engine speed. At equilibrium the force of the spring 8 counterbalances the suction on the diaphragm 14. If the pedal is operated to move the lever 6 to a reduced delivery position, the force of spring 8 is reduced and valve 12 moves to the right to open ports 17, whereby pressure fluid from reservoir 16 operates a bellows 18 to vary the field resistances 22, 24 of the generator and motor to reduce the generator speed to that defined by cam 6, whereby the valve 12 is returned to its equilibrium position. The generator resistance 22 is reduced to its minimum value before any increase is made in the motor resistance 24. Similarly if pedal 1 is depressed to increase the delivery, valve 12 moves to the left to correct bellows 18 to atmosphere and increase the generator speed.
