Title: A method of separating electrically charged particles
IPC: H01J49/34
Filed: 1958-06-06
Abstract: 878,042. Mass spectrometers. OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE G.m.b.H. June 6, 1958 [June 6, 1957], No. 18161/58. Class 39(1). A non-magnetic mass spectrometer comprises high-frequency modulating systems M1, M2, M3, Fig. 1 and an electrostatic deflecting system formed by the plates 2, 3 and 2, 4 of a parallel plate condenser plates 3 and 4 forming an integral construction. The spacing between the modulating systems is so arranged that only ions which gain maximum energy from the high-frequency fields pass through to the collector C. The modulating systems consist of high-frequency plates 7 between grounded plates 8 and 9. Plates 7 may be asymmetrically located relative to the outer plates in order to obtain an optimum transit time for the particles as regards maximum energy gain or loss. In a modification, Fig. 3, the ions are deflected by the plates 11, 12 of three cylindrical condensers. If more than three modulator systems are used, delay lines may be inserted between them.

Title: Process for the primary clouding of enamel glazes
IPC: C03C8/20
Filed: 1933-06-26
Abstract: 403,314. Glazes; glass. EYER, P., 151, Quedlinburgerstrasse, Halberstadt, Germany. June 26, 1933, No. 18176. [Class 56.] In the production of white or coloured enamel glazes which are clouded by adding zirconium to the melt, a zirconium opacifying agent and glass, together with other opacifying agents if desired, are added to the fusion charge. Soft glass is particularly suitable, for example a glass having the composition 100 parts of sand, 10 of lime, 10 of potassium carbonate, 21 sodium carbonate, and 1 of saltpetre. Opal glass may be used, and the presence of boric acid in the glass is beneficial. If zirconium oxide is used, it should be free from iron. The proportion of glass in the charge is preferably not above 15 per cent, and of zircon or zirconium oxide, not above 10 per cent. Proportions of 5 and 3 per cent respectively are suitable. The proportions of other opacifiers, containing alumina for example, can be increased beyond the ordinary figure without adverse effect. The use of " boron mineral," which term includes purified calcium borate or boracite, either in place of or in addition to borax, and preferably in amounts up to about 25 per cent, enables large amounts of opacifiers such as cryolite, alumina, or antimony oxide to be added. The mixed opacifiers, together with an oxidising agent such as saltpetre and sodium carbonate if desired, may be precalcined, for example at 700-1300‹ C., and the product added to the fusion charge. Examples of opacifying mixtures and fusion charges are given.

Abstract: 596,167. Liquid-fuel burners. RADIATION, Ltd., and BENNETT, A. R. July 23, 1945, No. 18843. [Class 75 (i)] A spray burner suitable for use in air-heating apparatus in aircraft is provided with a fuel valve m on a spring-loaded piston n sliding in a cylinder h having one end adjacent to the nozzle c, either the cylinder or the piston being provided with an orifice or orifices permitting fuel to flow from one side of the piston to the other to set up a pressure difference, variations in which serve to vary the effective area of the valve opening k. In Fig. 1, the cylinder h is provided with orifices q, p through which the fuel may flow, an excess of pressure causing the piston to move to restrict the ports k, the rate of supply of fuel to the nozzle being thus kept substantially constant. The set of orifices q may be controlled by a piston r on a rod s connected to an extensible capsule t, another rod abutting against the inner end of this capsule and being connected to an actuating means, such as a solenoid u with push-button switches. Regulation of the air supply may be effected by mounting a fixed distributer plate d in front of the nozzle and by providing two spring-loaded slidable control plates v, w so that an excess pressure difference between the air supply chamber y and the combustion chamber a causes the control plates to move towards the distributer plates, the perforations in the two sets of plates being staggered so that this reduces the air supply. For varying the rate of air supply with the rate of fuel supply, actuation of the solenoid u may also impart a sliding movement to a part 2 provided with pins 4 engaging in helical slots in the plate w so that this sliding movement rotates the plate w relatively to the plate v which is held against rotation as by a pin-and-slot connection with the part a. A barometric capsule 3 may also be provided to actuate the part 2 in response to variations of atmospheric pressure. In Fig. 2 the fuel supply is maintained substantially constant by a needle valve 8 extending'into a bore 6 of the piston n, an excess of pressure causing the piston to move to restrict the ports k. The needle valve 8 may be carried by a piston 9 acted on by a rod 10 operable by a lever 20 or by similar means to that of Fig. 1. The air supply is regulated in a similar fashion to that of the embodiment of Fig. 1, the plate v being carried by spring blades 12, 13 so as to be axially movable with respect to the fixed plate d, both plates v, w being mounted on a helically slotted sleeve 14 engaged by pegs 18 on actuating rods 19, so that sliding movement of these rods imparts rotary movement to the plates v, w.
