Title: Process for desaccharizing syrups and molasses
IPC: C13B35/00
Filed: 1928-02-14
Abstract: 308,867. BergÚ, J. Feb. 14, 1928. Refining sugar. - Syrup or molasses is desugared by distributing it in a thin layer over pure sugar crystals so that the crystals are surrounded, for example, by a uniform coating of 15 per cent of syrup. The surface of crystallization is thereby enlarged and the thickness of the syrup layer around the crystals is reduced. By suitably controlling the conditions of storage of the crystals, such as temperature and humidity, the effect of desaccharization of the syrup may be intensified. Pure sugar crystals may be added directly to massecuite to convert the latter entirely into raw sugar; or the crystals may be added only in such quantity that the mixture can be mashed and centrifuged, the syrup removed being mixed with excess of crystals as in the first method. Syrup may also be added in larger quantity to pure sugar crystals and the excess then removed so as to produce the requisite thin coating; the syrup thus separated may be mixed with a fresh batch of crystals. Syrup which has already been centrifuged may be sprayed upon sugar crystals in mass. When the syrup or molasses coating the crystals has been sufficiently desugared, it may be separated from the sugar crystals by centrifuges of correspondingly higher centrifugal force, the crystals being utilized again for desugaring. Specifications 3782/94 and 225,221 are referred to.

Title: An improved process for making glass, enamels, glazes and the like containing lead
IPC: C03C1/00
Filed: 1932-02-18
Abstract: 378,799. Glass ; glazes ; enamels. BEYERSDORFER, P., 59, Lobauerstrasse, Reichenbach, Oberlausitz, Germany. Feb. 18, 1932, No. 4815. [Class 56.] A process for making glasses, glazes, or enamels containing lead consists in adding the lead to the batch in the metallic form together with oxidizing agents, such as nitrates, in such quantity and of such oxygen content that the whole of the lead is converted into lead oxide during the melting process. The lead is added to the batch in the form of scales, granules, or in other finely-divided state, but preferably the lead is fused and is dispersed with one constituent of the batch, for example the sand. The mixture of sand and lead is stirred for about eight hours at a temperature of 400- 500‹ C. until a large part of the lead is oxidized, and is then mixed with the remaining constituents of the batch in a rotating drum. If colouring or opacifying agents, such as antimony, tin, copper or nickel are to be added, the metal itself is used if it will alloy with the lead. The alloy is first prepared and is then added to the batch. It is stated that the colour imparted to glass by ferrous oxide is more intense when lead is added in the metallic form.

Abstract: 473,464. Discharge tubes ; light-sensitive cells. ELECTRICAL RESEARCH PRODUCTS, Inc. Feb. 18, 1937, No. 4867. Convention date, March 4, 1936. [Classes 39 (i) and 40 (iii)] A screen scanned by electrons and upon which an optical image to be transmitted is projected comprises a conducting support to which is applied a thin film of high resistance photoconductive material, for example mercury iodide, native sodium chloride or an alloy of selenium with a higher resistance material. The elemental charges created by the scanning beam are discharged by leakage to an extent dependent on the elementary illumination. The screen may be mounted in a cathode-ray tube and scanned by a beam so as to produce either positive or negative charges, and the object may be imaged either on the scanned face or on the support if this is transparent. The film should be smaller than, for example onetenth of, the diameter of the scanning spot. In a modification the film 16 is mounted on a transparent support, comprises a glass plate 41 and a transparent silver coating 31, and a member M, comprising a glass plate 42, a transparent metallic layer 43, and a photoelectric coating 44 which may be made opaque e.g. by a coating of carbon, is arranged parallel to the plate 41. A spot of light or ultraviolet radiation is arranged to scan the member M, and photo-electrons in turn scan the film 16 on which the image is projected. The spot may be produced by a rotating disc and a source or by a cathode-ray tube with a fluorescent screen.

Abstract: 1,122,913. Soldering. M.E.L. EQUIPMENT CO. Ltd. 3 Feb., 1967 [7 Feb., 1966], No. 5223/66. Heading B3R. [Also in Division H4] A mound of solder is caused to be raised in a body of liquid solder by vibrating a probe containing titanium below the surface of the body. A probe 15 comprising 11% tin, 5% zirconium and smaller amount of molybdenum, silicon and aluminium with the remainder titanium or 6% aluminium, 4% vanadium remainder titanium is coupled to the vibrating element 13 of an ultrasonic generator 14 having a winding 12 thereon connected to the secondary winding 11 of a transformer 4. The primary 3 of the transformer is connected to a current supply line 5 and to the anode 2 of an oscillator triode valve 1, the cathode 6 of which is connected to a supply line 7 and the grid 8 of which is connected to the line 7 by a grid leak resistor 10. A feedback magnetostrictive transducer forming part of the generator 14 has its winding 16 on a core 17 connected between the supply line 7 and via a capacitor 18 to the grid 8. In operation a D.C. voltage is applied to line 5 to cause the valve 1 to conduct and current to flow through primary 3 which causes current flow in the secondary 11 and thus the vibrator 13 to be energized. A feed-back potential is thus applied to the valve grid 8 to provide an automatic frequency control. The liquid solder is caused to fall with a horizontal velocity component over a lip in a curved fall and the probe is disposed radially within the fall to produce a mound over which flat printed circuits are passed. The fallen solder is pumped up to the lip again. The supply voltage to line 5 may be intermittent or alternating current as described in Specification 1,082,874.
