Filed: 1929-01-30
Abstract: 315,259. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Howard, L. F.). July 10, 1928, [Convention date]. Arresting grips or friction apparatus on permanent way.-In brake apparatus for railway vehicles of the kind comprising a series of spring urged non-articulated brake bars arranged on the track for engagement with the sides of the wheels, the entering end of each bar is at a greater distance from the rail than the leaving end. As shown, a series of brake bars 6, 7 disposed respectively on the two sides of the track rail 1 are connected to a fixed bar 70 by springs G. The ends of the bars at which the wheels enter are as shown normally at a greater distance from the rail 1 than the leaving ends. The bars are arranged to be moved longitudinally so as to bring them to their operative position near to the rails by means such, for example, as are described in Specification 289,459. The springs G are so adjusted or designed that although each one of the series associated with a given bar is compressed to a greater extent than the preceding one as the wheel passes along, substantially the same pressure is exerted on the wheel at all points of the bar.

Patent GB-940660-A (GB)
Title: Improvements in and relating to the production of 5-nucleotides
IPC: C12P19/30
Filed: 1962-01-29
Abstract: 51-Mononucleotides are obtained by enzymically degrading nucleic acids by treating them with an aqueous extract of a vegetable material which extract shows 51-phosphor-diesterase activity, and separating the 51-mononucleotides formed from the reaction mixture. The extract may contain an organic solvent, e.g. chloroform and/or toluene.  The vegetable material is defined as consisting of plants, parts of plants which when growing are disposed above and/or below ground, e.g. fruits, seeds, tubers, roots and/or root crops and also plant embryos and mixtures of different plants or plant parts, if desired with embryos.  Crude extracts of seeds, germs and/or germ components of di- or mono-cotyledons, e.g. legumes, wheat, rice, barley and/or grasses, and the sprouts or germs obtained in the preparation of malt are particularly suitable and partially purified extracts, e.g. those obtained by calcium phosphate gel treatment followed by elution with ammonium sulphate and phosphate buffer solution and subsequent precipitation by acetone, methanol or ethanol are also suitable and the 51-nucleotidase present may be removed from the extract by chromatography prior to treatment of the nucleic acids. In a particularly preferred form of the invention the aqueous extract is exposed to a brief heat treatment, preferably in the presence of a heavy metal salt, before use in the process.  In carrying out this treatment the aqueous extract may, if desired, be treated with an organic solvent sparingly soluble or insoluble in water, e.g. toluene and/or chloroform and then heated at from 45 to 75 DEG C for e.g. 5 to 40 minutes in the presence of a heavy metal salt, e.g. a chloride, sulphate or nitrate of zinc, nickel or copper. In carrying out the enzymic degradation the r H of the aqueous extract should preferably be adjusted to a value of from 4 to 7 and if desired the process may be carried out in the presence of a buffer solution, e.g. a phosphate, phthalate, acetate or tris-(hydroxymethyl)-aminomethane buffer and such buffer may also be present during the extraction process to obtain the enzyme. In carrying out the degradation process the extract is added to a solution or suspension containing nucleic acids and the 51-mononucleotides formed are suitably precipitated as alkaline earth metal salts.  A simple yeast extract may be used as nucleic acid-containing material.  The reaction product obtained is a mixture of the nucleotides of adenine, guanine, uridine and cytosine and the individual nucleotides can be separated by anion exchanges.  The corresponding desoxyrisonucleotides can also be obtained when desoxyribonucleic acids are used as starting materials. Examples are given in which the extracts used are obtained from spinach leaves, carrot roots, potato tubers, linseeds (from which the oil has been removed), rose hips, the flour of defatted groundnuts, wheat oil germ, cleaned barley germs, and vacuum dried embryo roots of the broad bean.

Title: Improved means for reproducing sound
IPC: H04R3/14
Filed: 1923-02-05
Abstract: 215,104. Round, H. J. Feb. 5, 1923. Adjusting relative strength of different ranges of speech frequencies; magnetic instruments.- For transmitting or reproducing sound a number of magnetic, electrostatic, piezo-electric or other telephones with differently tuned diaphragms are connected in series with a variable shunt across each instrument. A suitable form of magnetophone is shown in Fig. 2 in which a central core F carries a magnetizing coil H and a line coil G, the magnetic circuit being completed through the diaphragm E and the case D. Adjustable rubber pads J are arranged adjacent the diaphragm. The diaphragms of different pitches may be constructed of iron of different thicknesses. A very good reproduction of the human voice is stated to be obtained by using two diaphragms tuned to frequencies of 6000 and 600, and for the reproduction of music in which bass is present five diaphragms are used tuned to frequencies of 200,. 500, 900, 2000, and 8000. Where sufficient mechanical damping cannot be obtained, the shunt may consist of inductance, capacity, and resistance. In a modification, the winding of a telephone having a diaphragm pitch about 2000 is connected with a plurality of filter circuits Q in parallel, each adapted to select a different range of frequencies, these ranges being amplified to the desired degree by thermionic valves R, S, and the results synthesized. A plurality of diaphragms differently tuned or a single diaphragm to which is applied a current distorted bv parallel filter circuits may be used in a loud speaker with a single horn of great effective length so that it is practically equally resonant to all frequencies above 100.

Abstract: 809,983. Charging sintering machines. UNITED STATES STEEL CORPORATION. Feb. 5, 1957 [April 19, 1956], No. 3995/57. Class 51 (2). [Also in Group XVIII] An apparatus for compounding sinter feed comprises an endless belt 21 passing beneath the outlets of hoppers 22, 23, 24 containing ore, scale and scrap (subsequently referred to as " ore "), hoppers 27, 28, 29, 30 containing coke, anthracite, flue dust and sized returns (subsequently referred to as " additives "), and a hopper 32 which contains " hot recycle " in the form of dust or unburned sinter not suitable as a sintered product; means for continuously summating the feeding rates of " ore " and " hot recycle "; and means for varying the feeding rates of " additives " in accordance with this summation. The rates of feeders 25 on the " ore " hoppers 22-24 and feeder 33 on the " hot recycle " hopper 32 are controlled manually through devices 51 and 57 and the operator maintains a substantially constant total weight of these constituents. A summator 38 receives inputs from a scale 26 which measures the weight of " ore " on the belt, and a summator 62 which measures the weight of " hot recycle " by calculating the difference in weight registered by two scales 60, 61, and feeds its output, which is proportional to the total weight of " ore " and " hot recycle," to ratio devices 39-42 which control the quantity of " additives " fed by feeder 31 in accordance with the output of summator 38 and the manual setting of proportion controls 52-55. A further ratio device 43 receiving signals from summator 38 and a manual control 56 controls the feeding of a predetermined quantity of water to the sinter feed as it reaches a pug mill 34. Control 57 operates controller 58, which varies the speed of feeder 33 through a time delay 59 which is such that an increase in the " hot recycle " feed occurs only when the section of the belt which has received. less " ore " reaches feeder 33. Indicators 63- 67 respectively give an indication of the level of " hot recycle " in bin 32, the weight of " ore " plus " hot recycle," the weight of "hot recycle," the weight of filter cake additive measured by a scale 68 and the total weight of feed passed from the pug mill 34 over a scale 69. In a modification (Fig. 3, not shown) the setting of the " hot recycle " feed rate automatically changes the ore feed rate. The weighing summating and ratio devices are not described but are stated to be either electronic or pneumatic devices such as those described in Specification 725,494, [Group XIX], and U.S.A.
