In a centrifugal mixer adapted to be immersed in liquid and comprising two relatively rotatable bodies A.C., each provided with at least one row of teeth H<SP>1</SP>, H, which in conjunction with the bodies form a central chamber, the liquid enters the chamber through inlets F<SP>1</SP>, F in at least one of the bodies and is expelled from the chamber periphery through the gaps between the teeth. In the construction shown in Fig. 1 both bodies are rotatable' but in modifications the body C may be fixed. Impeller vanes G within the chamber are carried by the body A, and their outer edges constitute the innermost row of the teeth H<SP>1</SP>. In the arrangement shown in Fig. 4, the mixer is mounted within a casing L having an outlet valve U and a valve N through which air escapes during filling of the casing. The material to be mixed passes through a pipe M to the central chamber, is expelled from the chamber periphery and returned to the chamber through the inlets F, the valve U being initially closed, then adjusted to permit continuous flow from the casing. In a modified arrangement (Fig. 5, not shown), gas or chemicals may be introduced during the mixing. The relative rotational speed of the bodies may be high enough to generate ultra-sonic vibrations.

Title: Improvements in and relating to the brewing of beer
IPC: C12C12/02
Filed: 1936-08-10
Abstract: Vegetable, in particular malt, diastase solution or extract is added at any stage from mashing to maturing, to materials which would otherwise produce normal beer.  The extract content of the finished beer is thus diminished, making it suitable for diabetic and corpulent persons.  The fermentation may also be in two stages first by ordinary yeast and then by a dextrine fermenting organism, e.g. Schizosaccharomyces Pombe.  The diastase extract may be obtained by extracting ground green malt with aqueous alcohol, and filtering, preferably including a degerminating filtration.  Specification 454,766 is referred to.

Abstract: 936,870. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. June 8, 1962, No. 22265/62. Class 39 (4). A heavy water moderated nuclear reactor for producing high flux thermal neutron beams comprises a vessel for containing the water, a removable portion containing highly enriched uranium fuel elements within the vessel and submerged in the water, inlet means above the removable portion and outlet means below the top of the removable portion for supplying and withdrawing the water, and means within and attached to the vessel for supporting the removable portion and for separating incoming and outgoing water, the reactor core being under-moderated but surrounded by a reflector so that the maximum thermal neutron flux is in the reflector. In Fig. 1 the reactor comprises a generally spherical vessel 12 closed at the top by a fuel handling cover 28 and supplied with heavy water flowing from an inlet 32 to an outlet 34. The removable portion is supported on a shoulder 36 and comprises an upper shroud 40 of cylindrical form and a lower shroud 44 which extends down to a grid plate 46 supported from the bottom of the vessel. As shown in Fig. 2 the lower shroud 44 comprises thirty rectangular cells of which twenty-eight contain fuel elements (not shown) and two contain irradiation tubes 84, 86. The core is under-moderated so that the maximum thermal neutron flux is in the surrounding reflector. Tubes 102, 104, 106, 108, 110 allow beams of thermal neutrons to be taken from the reactor and are arranged generally tangential to the core, to reduce fast neutron and gamma background, with their ends substantially in the region of maximum thermal flux. Tubes 112, 114 and 116 terminate closer to the core to obtain fluxes in the high energy levels. A cold beam tube 118 of extra large diameter permits a refrigerated moderator to be placed in the reflector region for the production of a low-energy neutron beam. An irradiation tube 88 may also be provided in the reflector region. Safety control rods 54 of L-shaped cross-section are slidable along the outside of the lower shroud 44 while auxiliary control rods 64 extend up through slots provided in grid plate 46.

Title: Improvements in or relating to high frequency electric transmission lines
IPC: H03H7/48
Filed: 1935-08-08
Abstract: 461,192. Distributing music &c. MANIFOLD, M. BOWMAN-. Aug. 8, 1935, No. 22453. [Class 40 (iv)] [Also in Group XL] In a carrier distribution system, reflection is avoided by including the load 7 at each tapping point in the shunt arm of a resistance T-network having an impedance equal to the characteristic impedance of the line. The load may be one or several receivers. Where the line is used for two carriers having widely different frequencies, e.g. À5 to 1À5 megacycles for sound signals and 40 megacycles for television, the networks are provided with tuned circuits to give the impedance of the shunt arm different values at the two frequencies, the impedance being still substantially purely resistive at both frequencies. This is necessary to ensure that all receivers at both frequencies receive signals at the same level. As shown, the circuit 14, 15 is tuned to the high-frequency and acts as a short-circuit to resistance 12 at the lowfrequency ; alternatively, a series tuned circuit tuned to the low-frequency may be employed. In further modifications, the shunt arm is constituted by a resistance in parallel with a circuit including in series a second resistance and a series resonant circuit tuned to the lowfrequency, or a parallel resonant circuit tuned to the high-frequency. Design formulae are given in the Specification.

Patent GB-1030745-A (GB)
Title: Aldehyde polymerisation process
Inventor: WARREN CHARLES KENNETH
IPC: C08G2/28
Filed: 1962-06-12
Abstract: A polymeric aldehyde is prepared by polymerizing at least one aldehyde in the presence of a polymerization initiator at a temperature below that at which the initiator would also act as catalyst for the degradation of the polymer so formed and the initiator is thereafter rendered ineffective as a catalyst for such degradation, the initiator being a compound having an alkali metal, alkaline earth metal, boron, aluminium, germanium, tin or lead atom directly linked to a monovalent group of the structure: -O-CmH2m-NR2, where m is a positive integer and R is a monovalent hydrocarbon radical or hydrogen.  The polymerization may be effected in the presence of acid contamination provided the amount of acid present does not substantially exceed 3 moles per mole of initiator.  After the polymerization and before allowing the product to heat up, the initiator is either extracted with a suitable selective solvent or a weak acid is added, if sufficient is not already present, to render it ineffective as a degradation catalyst on raising the temperature to that at which degradation of the polymer would normally occur. Aldehydes specified are formaldehyde, propionaldehyde, n-butyraldehyde, n-valeraldehyde, iso-valeraldehyde, n-caproaldehyde, cyclohexaldehyde, 2-ethyl hexaldehyde, benzaldehyde and phenyl acetaldehyde.  The polymerization may be effected in organic solvents that are liquid at the temperature of the polymerization and a number of these are specified.  In the examples, n-butyraldehyde is polymerized in pentane solution and in the presence of butyric acid with as the initiator either sodium N,N-diethyl-2-amino ethoxide or sodium N,N-dimethyl-3-amino n-propoxide at -78 DEG  C., acetone is added to the resultant polymer solution with additional butyric acid if necessary and the mixture is allowed to warm up to room temperature. Thermal instability of the polymers may be reduced by reacting the polymer with compounds to replace its terminal hydroxyl groups with more stable groups, such as carboxylate, by etherification or by the heat treatment described in Specification 980,516.  The polymers may be formed into shaped articles such as films, sheets, fibres and filaments. Conventional polymer composition additives may be incorporated.ALSO:Catalysts, used for the low temperature polymerization of aldehydes (see Division C3), consist of compounds having an alkali metal, alkaline earth metal, boron, aluminium, germanium, tin or lead atom directly linked to a monovalent group of the structure:- -O-CmH2m-NR2 where m is a positive integer and R is a monovalent hydrocarbon radical or hydrogen.  Monovalent hydrocarbon radicals specified are methyl, ethyl, propyl, isopropyl, isomeric butyl, cyclohexyl, phenyl, benzyl and tolyl radicals.  Catalysts exemplified are sodium N, N-diethyl-2-amino ethoxide and sodium N, N-dimethyl-3-amino n-propoxide.
