Abstract: 391,546. Protective cut-out arrangements. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine, Elektricitõts-Ges.; 2, Friedrich Karl- Ufer Berlin.) Jan. 15, 1932, No. 1273. Convention date, Jan. 15, 1931. [Class 38 (v).] Earth leakage protection of apparatus for example the generator or transformer 1 is effected by employing a wattmeter relay 4 tuned to a frequency different from the fundamental frequency of the apparatus so as to be particularly sensitive to the frequency superimposed on the apparatus by a frequency generator 7 which, as shown, may be located in the connection from neutral to earth. In this way selective protection against internal earth faults may be obtained without the use of very accurately matched summation transformers 3 which in conjunction with the transformer 5 in the earth. connection supply one coil of the relay the other coil being supplied with a current which is a measure of the voltage of the frequency generator. The resultant current from the transformers 3, 5 may be amplified by means of a thermionic valve and the amplified current supplied to the relay. Where the protected apparatus has an insulated neutral, an artificial neutral may be formed and to this neutral the frequency generator connected. The frequency generator may be brought into use only on fault.
Patent GB-1005341-A (GB)
Title: Improvements in and relating to methods and devices for applying coatings by vaporisation
IPC: C23C14/24
Filed: 1963-01-11
Abstract: <PICT:1005341/C6-C7/1> In vapour depositing coatings, e.g. of metals, semi-conductors or other materials, on a collector, e.g. heat sensitive microscope specimens, heat rays from the vapour source are prevented from reaching the collector.  As shown, heat and vapour rays from a furnace 3 are split into impulses by a rotating cylinder 1 having apertures 2.  Because of the geometry of the apertures 2, heat rays entering the cylinder are intercepted by the cylinder's opposite side, whereas the slower moving vapour rays can pass through to a collector 6 via an aperture in a diaphragm 7. Instead of a single hollow cylinder, two can be used which rotate in the same direction or counter to one another and are arranged one above the other or one inside the other.  The same end is achieved by two discs rigidly connected by a common shaft and provided with apertures staggered with respect to one another.  A further embodiment comprises apertured spaced screens which can be set in motion in phase displacement to one another.
