Title: Improvements in apparatus for the mechanical upkeep of railroad tracks by the filling method
IPC: E01B27/18
Filed: 1933-11-21
Abstract: 434,096. Delivering measured quantities of granular materials. LAMBLIN, G., 89, Rue de la Carnoy, Lambersart, Nord, France. Nov. 21, 1933, No. 32441. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 30, 1934]. [Class 106 (v)] [See also Group X] Ballast is delivered in measured quantities beneath the ties 50, Fig. 2, of a railway track by a wheeled machine comprising a hopper 5, a measuring device 4, and two discharge spouts 6 disposed one on each side of the rail 3. As shown in Figs. 6 and 7, the measuring device comprises two concentric hollow cylinders 9, 11. The inner cylinder 11 is secured to a shaft 7. and has a cut away portion bounded by two radial walls 12. The outer cylinder 9 also has a cut away portion having one radial end wall 10. By relative adjustment of the two cylinders the capacity of the measuring compartment between the wall 10 and one of the walls 12 can be varied. The two cylinders are then interlocked and rotated by a handle 20 on the shaft 7 to deliver the ballast to the spouts 6. The capacity of the measuring chamber is varied by a spring-controlled catch 16 carried by the handle 13 on the hollow spindle of the outer cylinder and adapted to engage between the teeth of a toothed segment of a member 17 secured to the shaft 7. This catch serves to interlock the cylinders for simultaneous rotation by the handle 20.

Abstract: 366,094. Valve generating circuits. DAVID, P. B. F., 56, Rue de Vaugirard, Paris. Oct. 29, 1930, No. 32537. Convention date, Nov. 23, 1929. [Class 40 (v).] To obtain oscillations of constant frequency, a twogrid valve is employed and both grid circuits are coupled to the plate circuit, the grid circuits including either biasing batteries, or leak resistances shunted by capacity. As shown in Fig. 2, the tuned plate circuit 3 is coupled to a coil 6 which has separate adjustable tappings connected to the grids 4, 5 through grid leaks and capacities 10, 11. In one modification. Fig. 1 (not shown), biasing batteries replace the elements 10, 11 whilst in another modification, Fig. 3 (not shown), the two grids are directly connected to each other and only a single resistance-capacity element is used. Either grid coil may be tuned instead of the plate ; and an additional space-charge grid may be used.

Patent GB-764314-A (GB)
Title: Phosphorus-containing polymers of the alkyd resin type
IPC: C08G63/692
Filed: 1954-11-11
Abstract: The invention comprises liquid and solid polyesters of one or more polycarboxylic acids and one or more of the compounds: tetrakis hydroxymethyl phosphonium (THP) salts, tris hydroxymethyl phosphine oxide (THPO) and their derivatives containing two or more methylol groups linked directly to a phosphorus atom. Suitable THP salts are the chloride, bromide, acetate, sulphate and phosphate.  The derivatives may be obtained by reaction with a nitrogen compound containing at least one hydrogen or one CH2OH group attached to a trivalent nitrogen atom, e.g. melamine, methylolmelamine, acrylamide, diacetamide, lysine, diethanolamine, cetylamine, ethylamine, ammonia and hydrazine. Suitable polycarboxylic acids are oxalic, malonic, sebacic, methyl-succinic, malic, tartaric, maleic, itaconic, aconitic, pinic, hompinic, phthalic, terephthalic, benzene tricarboxylic, diphenic and chlorendic acids and their anhydrides, acid halides and esters.  The reaction may be effected in the presence or absence of solvents such as ketones, ethers and hydrocarbons, or catalysts such as sulphuric, phosphoric and benzene sulphonic acids, alkali metal alkoxides and granulated magnesium. The preferred phosphorus reactants are THPO and mixtures of THP salts and THPO predominating in the latter.  The polymers are resistant to burning and are compatible with other polymers, e.g. alkyds. They may also be used in the partially polymerized state to modify other partial polymers by copolymerizing.  Examples of such polymers are polyesters, cellulose esters and other phosphorus polymers described in Specifications 740,269, 761,985 and 764,313.  A modified alkyd resin may also be produced by reacting the phosphorus compound and polycarboxylic acid compound with a polyhydric alcohol.  A number of examples is given including such features as a final heating of the polymers with triethanolamine, the production of filaments from a chlorendic anhydride-THP chloride reaction product, and the preparation of a polyester from dimethyl terephthalate, ethylene glycol and THPO which can be cast into films or extruded into fibres.

Abstract: 737,846. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 30, 1953, No. 33163/53. Class 38 (2). In a D.C. power transmission line connecting a rectifier and inverter, associated with each smoothing inductor is a second inductor of the same order of magnitude to which is connected a resistor and, if desired, a capacitor, whereby overvoltages due to oscillations following a disturbance of operating conditions are kept to a sufficiently low value. The second inductor 5 may be connected in series with the smoothing inductor 4, and have in parallel with it, resistor 6, and capacitor 7 and resistor 8, Fig. 1. The capacity C of capacitor 7 should be of the same order of magnitude as the line capacitance, and the resistance of resistor 6 should be of the order of magnitude #L/C, where L is the inductance of either inductor. Alternatively as shown in Fig. 2 the second inductor 10 may be connected in parallel with smoothing inductor 9, and have in series with it resistor 13 and capacitor 11 with its parallel connected resistor 12. The two inductors 9, 10 together have the value of the desired smoothing reactance. So that the values of the other components and of the insulation may be selected as desired, they may be connected in auto-transformer (Fig. 3, not shown) or full transformer (Fig. 4, not shown) connection.

Title: 4-aminosalicylaldehyde derivatives and the manufacture thereof
Inventor: SEYMOUR DONALD EDWIN
Filed: 1949-12-29
Abstract: The invention comprises 4-aminosalicylaldehyde derivatives of the formul  <FORM:0684616/IV (b)/1> and <FORM:0684616/IV (b)/2> in which Ac is an acetyl group.  The invention also comprises the preparation of the second compound by acetylating a compound of the formula <FORM:0684616/IV (b)/3> which may then be subjected to mild alkaline hydrolysis to produce the first compound.  In an example, 4-nitro-2-acetoxybenzal-diacetate is hydrogenated to give the 4-amino compound which is then acetylated with acetic anhydride and sodium acetate to give the tetracetate.  On treatment with thiosemicarbazide, the tetracetate yields 4-acetamido-2-acetoxybenzaldehyde thiosemicarbazone, which may then be hydrolyzed in cold alcoholic caustic soda solution to give 4-acetamido-2-hydroxybenzaldehyde thiosemicarbazone.  The latter compound may also be made by hydrolysing 4-acetamido-2-acetoxy-benzal-diacetate, acidifying with sulphuric acid, and condensing the 4-acetamido-2-hydroxy-benzaldehyde which separates with thiosemicarbazide.  Specification 683,392 is referred to.

Title: A process for the production of vinyl chloride-vinylidene chloride graft polymers
Inventor: HARDT DIETRICH
IPC: C08F255/02
Filed: 1964-08-18
Abstract: Graft polymers are made by polymerizing, in the presence of a free radical catalyst, vinylidene chloride or a mixture thereof with vinyl chloride while in contact with a preformed copolymer of ethylene and a vinyl ester of a C1-C8 monocarboxylic acid, the preformed copolymer containing 20 to 80% by weight of the vinyl ester, preferably vinyl acetate, and the ratio of monomer to preformed polymer being from 5 : 95 to 90 : 10.  Also present may be other monomers, such as unsaturated carboxylic acids and their alkyl, alkenyl, hydroxyalkyl, aminoalkyl and isocyanatoalkyl esters, and also their amides and N-substituted amides, vinyl esters and maleic anhydride. Free-radical catalysts specified are organic and inorganic peroxides, azo compounds and redox systems.  The grafting reaction may be carried out in organic solution or aqueous emulsion, but is preferably effected in aqueous suspension by first dissolving the copolymer in the monomer with the addition of initiator and dispersing the mixture in water with the aid of dispersing agents.  The resulting graft copolymers may be cross-linked by the action of peroxides or high energy irradiation, or, if reactive groups are present in the products, by reaction with polyfunctional compounds reactive with said groups.
