Abstract: 728,179. Luminescent screens. RADIO CORPORATION OF AMERICA. March 20, 1953 [March 25, 1952], No. 7800/53. Drawings to Specification. Class 39 (1). A luminescent screen for a colour television receiver has a multiplicity of phosphor triads, in which the red elements are zinc selenide, or zinc cadmium selenide having at least 8 parts Zn to 1 part Cd by weight, plus 0.003 to 0.03 per cent Cu activator, the blue elements are zinc sulphide or zinc seleno-sulphide having at least 8 parts S to 1 part Se by weight plus 0.005 to 0.025 per cent Ag activator, and the green elements are zinc silicate plus 0.1 to 1.0 per cent Mn activator. In the zinc cadmium selenide the ratio of Zn to Cd is preferably 25: 1. The zinc sulphide or seleno-sulphide may have 0.015 per cent Ag activator. The red and blue phosphors are prepared by firing at 750- 1250‹ C., preferably in a nitrogen atmosphere, using 2 per cent of NaCl or NH 4 Cl as a flux. The colour emission shade can be varied by varying the firing temperature and also, in the case of the blue phosphor, by varying the S : Se ratio. The green phosphor is preferably zinc orthosilicate with 0.3 per cent Mn activator. The tri-colour elements may be lines, dots or triangles, and may be disposed in one or more planes, or angularly as on the sides of pyramids, ridges or cells. The screen may be transparent, for example if elements of one colour are on one side and the elements of the other two colours are on the other side, or opaque, and may be flat or curved. The preferred red phosphor comprises 97 parts of Zn Se, 3 parts of Cd Se and 0.01 parts Cu activator. The deepening effect on the colour of increasing the percentage of Cd Se from 1-10 per cent is indicated graphically, Fig. 2 (not shown). Prior art phosphors for colour television receivers are referred to as follows: (a) blueemitting calcium magnesium silicate with 1 per cent Ti activator, (b) red-emitting cadmium borate with 1 per cent Mn activator, (c) redemitting zinc orthophosphate with 1 per cent Mn activator, (d) green zinc silicate with Mn activator (willemite).

Filed: 1953-03-23
Abstract: 726,105. Optical sighting apparatus; levels. MAZZON, C. March 23, 1953, No. 7922/53. Classes 97 (1) and 97 (3). In instruments having a telescope the axis of which is displaceable by rotation before the objective of a transparent plate having plane parallel faces, the plate simultaneously displaces the axis of a second optical system, parallel to the first, whereby the movement of the image of a fixed scale, formed by the second system, gives a measure of the displacement of the axis of the first system. The drawing shows a dumping level having a telescope O1-O1 before which is a parallel faced plate L. Attached to this telescope so that their axes are parallel is a second telescope O2-O2 through which a scale S2 is visible. The plate L is rotated by an arm M and crank F on rotation of a wheel B and causes displacement of the axis C1 of the first telescope and an equal displacement of the axis C2 of the other telescope, which displacement is measured on the reticle of the second telescope.

Title: Electric switching arc suppression circuit
IPC: H01H9/54
Filed: 1958-03-12
Abstract: 849,240. Sparking preventing in switches. AMERICAN MACHINE & FOUNDRY CO. March 12, 1958 [April 12, 1957], No. 8005/58. Class 38 (5). A rectifier (or rectifiers) 16 having minority carrier storage is in series with a biasing battery 18 across the contacts 12 of a switch in the circuit from a battery 10 to a load 14. When the contacts 12 are closed they complete a circuit for the battery and rectifier which is thus biased in a forward direction. When the contacts 12 are opened the rectifier conducts in the reverse direction for a short period, and prevents arcing across the contacts, but its resistance quickly increases to a very high value. A switch 20 may be included in the rectifier circuit and arranged to close just before the contacts 12 open and to open when the need for arc suppression is past. In an A.C. circuit the switch 12 with the rectifier and biasing source are mounted in a rectifier bridge (Fig. 3, not shown). In Figs. 4 and 5 (not shown), the bias is derived from the main supply source by suitable means.
