Abstract: 1436497 Flowmeters METCO Inc 29 July 1974 [7 Nov 1973] 33358/74 Heading G1R A flowmeter of the variable-orifice type for fluids such as gases has an inlet 28, a piston-like float 20 fitting slidably within a tube 16, which tube has a slot 18 providing the variable orifice from which the fluid passes to the chamber 30 outside the tube and hence to the outlet 14. The float 20 is extended through a closely-fitting guide 12 in the housing 10 into a sealed sight glass 32. This, in addition to providing an indication of the height of the float and hence of the flow, forms a shock absorber to damp the oscillations of the float which result from sudden changes in the flow. The tube 16 and the sight glass 32 are sealed by O-rings 9. The tube 16 can be adjusted vertically by means of a collar 26 and the zero position of the float can be varied by using different-sized stop collars 29 to provide zero adjustment. In an alternative embodiment a by-pass controlled by a valve connects the inlet 28 with the chamber 30 for zero adjustment.

Abstract: 934,417. Semi-conductor amplifiers. PYE Ltd. Sept. 25, 1961 [Sept. 29, 1960], No. 33470/60. Class 40 (6). An amplifier circuit comprises a silicon controlled rectifier arranged to control the switching of a D.C. power source to a load, the siliconcontrolled or like rectifier being controlled by a switching signal consisting of a train of pulses whose width or time duration depends on the instantaneous amplitude of the signal to be amplified. In the Figure an audio signal and a triangular waveform, derived from multivibrator 1 which runs at twice the maximum audio frequency, are fed into combiner 3. The combined output is fed to a Schmidt trigger circuit 5, amplified at 6 and used to switch on a PNPN silicon controlled rectifier X 1 , in series with the primary of an output transformer T. A differential output from the amplifier is applied to a further S.C.A. or to a transistor to extinguish X 1  at the end of the pulse. The secondary of the output transformer T feeds the load L, which may be a modulator or a loudspeaker, via a filter F which removes the switching frequency.

Abstract: 1430682 Fused silica doped with phosphorus CORNING GLASS WORKS 29 March 1973 [30 March 1972] 33531/75 [30 March 1972] Divided out of 1430681 Heading C1M A method of making articles of fused silica of high optical quality which are optically transparent, water-free and free of gaseous occlusions, in which a silicon-containing soot doped with phosphorus alone or in combination with other doping agents is deposited upon a mandrel comprises the steps of depositing on to a non- metallic mandrel a soot formed by flame hydrolysis of a silicon compound so as to form a preform, the burner used in said flame hydrolysis being sufficiently close to the mandrel that the said mandrel is within the outer cone portion of the flame from said burner, and said mandrel being translated and rotated for depositing a uniform dense soot, and gradually inserting said mandrel with said soot deposited thereon into a furnace at a rate sufficient to sinter the soot and at a rate which permits entrapped gas to escape through portions of the soot not in the hot zone of the furnace as soot is sintered and shrinks around the mandrel. Suitably PCl 3  is mixed with SiCl 4  and the mixture flame hydrolysed. Layers up to 1 inch may be deposited. The mandrel may be of graphite, refractory or crystalline ceramics, e.g. Al 2 O 3 , mullite, BN or SiC, glass or glass ceramic. An induction furnace having a temperature of 1400-1700 C. is particularly suitable and the preform is preferably passed into the furnace at 0À1-1À0 inches per minute. An inert dry atmosphere, e.g. nitrogen, helium, neon or argon, is preferably maintained in the furnace to avoid oxidation of the graphite mandrel. As the preform is gradually inserted into the furnace it generally has air entrapped in it. As it moves into the furnace this is replaced by the inert gas which is then easily dissolved in the glass during its sintering. In the embodiment specifically described the mandrel is inserted downwardly into the furnace. After the preform is consolidated it is quickly removed from the furnace. Optical waveguide blanks which are tubes having a 1 inch outside diameter, a  inch inside diameter and a 4 inch length may be produced.

Title: A process for the removal of impurities of an organic nature from aqueous solutions of sugars
IPC: C13B20/14
Filed: 1945-12-12
Abstract: Impurities of an organic nature are removed from aqueous solutions of sugars by treating the solutions with water-insoluble synthetic resin gels which have been obtained by the condensation of aldehydes with phenols or with aromatic amines in an aqueous medium, and which have undergone no or substantially no after-treatment by drying, any proteins present in the sugar solutions being removed as far as possible before the solutions are treated with the gels, preferably by precipitation with bentonite at a pH of between 4 and 7.  The treatment with the resin gels may be combined with one or more treatments with cation- or anion-exchanging substances, preferably with hydrogen- or hydroxyl-exchanging substances, these treatments preferably comprising a pre-treatment with a cation-exchanging substance and a subsequent treatment with an anion-exchanging substance.  The gels may be used both in suspension and preferably in fixed layers, if desired, together with other adsorbents or with filter aids such as diatornaceous earths or activated carbon; they can be regenerated by treatment with alkali followed by treatment with acid.
