Abstract: 488,776. Rope railways; brakes. STRUNK, G. Oct. 11, 1937, Nos. 27604 and 27605. Convention dates, Oct. 12, 1936 and Feb. 23, 1937. [Class 104 (ii)] [Also in Group XXXIV] Apparatus for moving or braking railway vehicles coniprises one or more endless chains mounted on pulleys 14, 15 on a frame 10 arranged in a gap in the rail track 11, so that cars running on to the chains are moved across the gap. The run of the chain engaging the wheel peripheries may be at the level of the rails 11, or it may be at the level of the tops of the wheels. The chains run by means of rollers 19 in a channel rail 20 which is pushed up by springs 28 so as to force the wheels against a fixed rail 29, and force the chains tightly against the wheels. Alternatively, the track 20 may be fixed and the rail 29 forced down by springs. The wheels in passing from the rails 11 on to the chains and from the chains to the rails run on bridge plates 27 connecting the rails to the frame 10. By applying a brake to the chains instead of driving them, they may, in co-operation with the clamp rails, be used for slowing down cars. The chains may be driven by a motor 22 through a gear box and worm gear, or by a reciprocating motor having two piston-rods provided with racks engaging pinions coupled by free-wheels to the shafts 12, 13. In another form, the chains are formed of links carrying shoes guided and supported on the upper rim by a beam of U- section. A brake drum is mounted on the shaft 13, and the brake band is connected to a piston in a compressed air cylinder with manual control means. In another form, the cars after leaving the rails 11 pass on to an inclined track up which they are moved by a chain having fingers &c. engaging the car axles.

Patent GB-363426-A (GB)
Title: Improvements in the treatment of materials made of or containing cellulose derivatives
IPC: D06M13/07
Filed: 1930-09-24
Abstract: A subdued lustre is imparted to filaments, yarns, bristles, films, and other materials made of or containing cellulose acetate or other organic derivative of cellulose, by treatment with a mixture of a solvent for the cellulose derivative and a non-solvent therefor, and allowing or causing evaporation of the mixture on the material so that its solvent power decreases. Preferably the proportion of non-solvent to solvent in the mixture is such that while the mixture is not a solvent yet it has a marked swelling power for the cellulose derivative, a marked reduction in lustre being obtained provided a considerable swelling takes place; with limited proportions of solvent, the delustring effect is confined to the surface of the materials.  It is convenient to apply only limited proportions of the mixture to the materials to be treated, for instance, 10-40 per cent of their weight.  The liquid may be applied to the materials in transit, either from the wet or dry spinning machine in-which they are made or while winding from one package to another, and the actual application may be by means of wicks, rollers, or discs or of a spray, or the mixture may be applied in the form of a printing paste by engraved or embossed rollers.  To obtain differential effects, the application may be intermittent, or local as by spraying or brushing through stencils, or by printing methods; and in the case of a fabric, either or both surfaces may be treated. Suitable solvents are acetone, ethylene dichloride either alone or with the addition of ethyl or methyl alcohol, mixtures of methylene chloride and ethyl or methyl alcohol, dichlorethylene, and dioxane; as non-solvents, xylene, benzene, toluene, mesitylene, water and alcohol may be used. In examples, to cellulose acetate yarn is applied by means of a wick, roller, &c., a mixture of 70 per cent acetone and 30 per cent xylene or a mixture of 40 per cent acetone and 60 per cent water, the application taking place either continuously with the manufacture of the yarn or subsequently thereto; fabrics, films, &c. of cellulose acetate may be covered with stencils and the above mixtures brushed or sprayed over the stencils to produce delustred patterns on the materials; or the mixture of acetone and xylene is thickened as by means of calcium or aluminium resinate or other metallic soaps with the addition of a small amount of oil to reduce the adhesive properties of the paste, which is applied by means of print rollers. Specifications 277,089, 323,790, and 336,217, [all in Class 2 (ii), Cellulose &c.], are referred to.

Title: Method and apparatus for estimating the free sulphate ion content in phosphoric acid slurries
Inventor: HALL RAYMOND FREDERICK
IPC: G01N25/48
Filed: 1965-07-08
Abstract: 1,125,287. Determining free sulphate ion in slurries. FISONS FERTILIZERS Ltd. 28 June, 1966 [8 July, 1965], No. 28961/65. Heading B1X. The free sulphate ion in a wet process phosphoric acid slurry is determined by reacting, in measured proportions, the slurry with a liquid reagent which undergoes an irreversible exothermic reaction with sulphate ion and virtually no thermal reaction with the slurry, and measuring the rise in temperature produced by the reaction. The reagent preferably contains barium, lead or strontium ions, e.g. a solution of barium phosphate in aqueous phosphoric acid of strength equal to that of the process acid, which lead to the formation of an insoluble precipitate with sulphate ion. The dermination_ is effected using a vessel 1 immersed in the slurry for batch operation. Slurry enters under hydrostatic pressure through filter 18 with valve 11 open, the vessel having been previously purged of all liquid by compressed air. During the entry of the slurry, a pre-set vol of reagent is forced slowly into vessel by meter 16, the combined mixture rising to level probe 14 which then closes valve 9. The rise in temperature is measured by thermocouples 7. With continuous operation the vessel is out of the slurry and has two inlet tubes for slurry and reagent.

Title: Improvements in or relating to oscillation generators for multifrequency signalling systems
IPC: H04M1/50
Filed: 1959-08-25
Abstract: 873,189. Substation circuits. WESTERN ELECTRIC CO. Aug. 25, 1959 [Sept. 8, 1958], No. 29043/59. Class 40 (4). [Also in Group XL (c)] A two-tone generator for replacing the dialling system of a telephone, comprises two resonant circuits of different frequency connected in a transistor circuit to determine the oscillation frequencies of the circuit, each resonant circuit being associated with a non-linear element for determining the amplitude of oscillation and each being normally coupled to a supply voltage for the circuit in such a manner that when a push-button is operated to select the frequencies to be transmitted, it breaks the connection to the D.C. supply and so initiates oscillation. The Figure shows a telephone line 11 connected to a bell 12a and through switch-hook contacts to a two-frequency oscillator and to a conventional telephone sub-set 15. A pair of resonant circuits comprising respectively inductor 36 and capacitor 37 an inductor 44 and a capacitor 45 are arranged in series and provided with push-button contacts so that the respective capacitors are connected to tappings on the inductors to cause the circuit to be resonant at two frequencies appropriate to the particular button depressed. These resonant circuits are coupled respectively to two feed-back transformers 86, 76 and 83, 73 of a transistor biased to operate a class A condition so that the circuit oscillates at the frequencies determined by the resonant circuits and at amplitudes determined by non-linear circuits 84, 87 connected across the transformers and comprising two diodes with a threshold voltage of about 0.7 of a volt connected back-to-back. The D.C. supply for the transistor is derived from two similar backto-back diodes 30 connected in series with the line to the exchange. Operation of any of the push-buttons operates a contact 26 which removes a short-circuit which normally by-passes the ring circuit and also by-passes the sub-set through a path including a resistor 28 which permits only a small amount of the tones to reach the receiver of the sub-set. The resonant circuits are normally connected across the line so that current flows in the inductors. Operation of contact 26 by any of the push-buttons breaks this connection causing oscillation to commence at full amplitude, thus avoiding the exponential build-up of the oscillation envelope. The diodes 30 could be replaced by a series resistor shunted by a capacitor. Specification 854,375 is referred to.
