Abstract: 1,195,468. Ore agglomerate. BLOCKED IRON CORP. 16 Feb., 1968, No. 7816/68. Heading C1A. A high strength ore agglomerate which is partially self reducing on heating is produced by admixing finely divided metal ore, at least one alkaline earth metal oxide or hydroxide, a carbonaceous material which is coal, coke, graphite, coke breeze or charcoal and water, forming this admixture into lumps and reacting the lumps with carbon dioxide. There may also be present in the admixture up to 1% by weight of the admixture of an alkali or alkaline earth metal salt of a mineral acid, and/or up to 2% by weight of the admixture of a solubilizing agent for alkaline earth metals which may be blackstrap molasses, glucose, fructose, dextrose or syrups, and/or 0À1 to 1À5% by weight of the admixture of an alkali metal oxide or hydroxide. The carbonaceous material may be coal having a fineness of 4 mesh or under and may be present in an amount of 1 to 35% by weight of the admixture. The alkaline earth metal hydroxide or oxide, such as lime, may be present in 5 to 20% by weight of the admixture. The moisture content may be less than 10% by weight of the admixture. The agglomerate gives a high percentage of elemental iron on heating to 1700-1900‹ F. The examples use hematite or tacowle ores.

Filed: 1932-03-16
Abstract: 392,707. Draining engine cylinders. SKODA WORKS, PLZEN, 37N, Jungmannova, Prague. March 16, 1932, No. 7853. Convention date, April 4, 1931. [Class 122 (i).] Draining means for auxiliary engines of locomotives comprises a cut-off member 2 mounted in a casing 1 adjoining the chamber 3 to be drained ; the member 2 carries a throttle member 6 upwardly pressed by a spring, and is controlled by a rod 4. On starting the engine at no load, the rod 4 is moved to the position of Fig. 4, in which the cut-off 2 is raised, but the throttle 6 is also raised into the constricted part of the casing 1, thus opening small drainage area between the members 1, 6 which may have incisions. When the full pressure of steam is admitted to the chamber 3 it depresses the throttle 6, so enlarging the outlet to permit complete draining. The rod 4 is then moved to the position of Fig. 2 to close the outlet. On stopping, the rod is again moved to the position of Fig. 4 to permit draining. The escaping steam passes into a receiver 8 having exhausts 9. Several draining devices may be operated by a common rod 4.

For transferring the vehicle A on to the trolley, the latter is provided at one end with hinged ramps or guides 6, 7 which are dropped to their operative position by movement of a control lever 13 and connections 22 .. 25, and in such position have brake-blocks on their under surfaces bearing upon the wheels 3 to prevent movement of the latter. In addition, the framework 1 is fitted with spring gripping-jaws 17, which are also controlled from the lever 13 through linkwork 15, 16 and are arranged to grip or to release a hook 18 on the vehicle A. The control lever 13 is also adapted by a tension member 19 to lower spring-controlled hinged spikes or abutments 20 and force them into the ground preparatory to running the vehicle A on to the trolley. Movement of the lever 13 in the opposite direction permits the ramps 6, 7 and abutments to be raised to their upper position, and the jaws 17 to close on to the hook 18, the trolley being then ready for travel. The framework 1 may be provided with springs 26 in order that it may normally bear a portion of the weight of the endless-track vehicle, and means may be incorporated whereby this share of the load may be increased. In the arrangement shown, the vehicle A bears upon the ends of arms 29 of bell-crank levers 28, 29, the other arms 28 of which are connected by rods 30 to a turnbuckle 31. In modifications, the ramps 6, 7 are stationary, but are provided with hinged terminal sections, and may be fitted at each end of the vehicle, while a hydraulic jack may be arranged to transfer a portion of the load to the framework 1.

Title: Improvements in or relating to gas analysers
IPC: G01N21/37
Filed: 1947-03-24
Abstract: <PICT:0642725/III/1> In a known system for detecting the presence of a particular gas depending on the fact that a given gas absorbs infra-red energy mainly from a characteristic portion of the spectrum, radiant energy from heaters A interrupted by a rotary shutter i is passed through similar tubes B to similar chambers C containing the gas in question and communicating with the respective halves of a third chamber divided by a diaphragm D.  One only of the tubes B contains the sample to be tested.  In the absence of the gas from the test sample, both tubes pass the characteristic radiation equally to chambers C and no effect is produced.  If, however, the gas is present, the characteristic radiation is absorbed by the sample and the associated chamber C is heated less than the other. As a result a pulsating pressure difference is caused between the two chambers and the resulting vibration of the diaphragm D which forms a condenser with a perforated plate is detected electronically.  In the present invention, the system is adapted for the detection of two or more gases by filling the chambers C with a mixture of these gases and providing filters F for the absorption of those parts of the spectrum that are characteristic of the gas or gases with which any particular test is not concerned.  A single filter only may be used since the tube B used for comparison purposes contains dry CO2 free air and may be partially blanked off to keep the energy in the two paths the same.  Liquid or solid filters may be used.

Abstract: 484,848. Variable speed toothed gearing. GES. ZUR KONSTRUKTIONUND VERWERTUNG AUTOMATISCH MECHANISCHER GETRIEBE. March 18, 1937, No. 8026. Convention date, March 18, 1936. [Class 80 (ii)] In automatic variable-speed toothed gearing for vehicles &c. in which the change of gear is speed-controlled, the driving fly-wheel 1 carries flanges 2, 3 adapted to be connected by centrifugal segment clutches 13, 5, 20, operating at similar speeds, to toothed wheels 25, 24, and the driven shaft 17, respectively. A lay-shaft 28 carries rigidly wheels 27, 31, gearing respectively with the wheel 25 and a wheel 32 connected by a one-way clutch 34 to the driven shaft, and is connected by a one-way clutch 30 to a wheel 26 gearing with the wheel 24. The speed of the engine determines the engagement of the clutch 5 with the low-speed wheel 24, which drives the shaft 17 through the lay-shaft and at the same time drives the wheel 25 at reduced speed. When the speed of the wheel 25 increases sufficiently the clutch 13 is engaged and the wheel 25 is driven by the engine, the one-way clutch 30 overrunning, and the shaft 17 is driven at an increased speed, lower than that of the engine, through the lay-shaft. When the speed of the driven shaft 17 increases sufficiently, the clutch 20 engages and a solid drive is obtained, the one-way clutch 34 overrunning. More than three speeds may be provided for.

Title: Neutron detector or dosimeter
IPC: G01T3/08
Filed: 1965-02-25
Abstract: 1,056,012. Detecting neutrons. BOEING CO. Feb. 25, 1965 [Feb. 27, 1964], No. 8242/65. Heading G6P. In a neutron detector, the property of nickel oxide, that its electrical resistivity varies in proportion to the lithium present, is used to provide an electrical output. The concentration of the lithium in the nickel oxide may be varied in accordance with two separate reactions. First, boron is added to the nickel and the reaction B10 (n, alpha) Li<7> takes place. Lithium (i.e. Li<7>) is formed within the nickel oxide mass during neutron irradiation and the resistivity of the nickel oxide changes with time as the irradiation proceeds. Secondly, lithium-6 may be added to the nickel and the reaction Li<6> (n, alpha) H<3> occurs. In this case, lithium is removed during neutron irradiation and the nickel oxide resistivity changes, as the irradiation proceeds, in the opposite sense to that of the first reaction. The detector may be incorporated in a Wheatstone bridge.

Title: Improvements in the manufacture of paper pulp
Inventor: DESORBAY GERMAINE MARIE HENRIE
IPC: D21C3/16
Filed: 1946-03-18
Abstract: Wood or other vegetable material is converted into cellulose pulp for the manufacture of paper by a process comprising a treatment in the cold with nitric acid of about 30 DEG  Baume (41 per cent), with concomitant cooling, and after removal of most of the nitric acid, a subsequent treatment with caustic alkali lye at a temperature not exceeding 35 DEG  C.  The used nitric acid and caustic alkali lye may be recovered and used for treating further batches of cellulosic material.  In an example, conifer wood is treated at 15 DEG  C. with nitric acid of 30 DEG  Baume.  After several hours, the nitric acid is substantially removed and, if desired, the material may be rinsed. The material which still contains some nitric acid is then treated with caustic soda lye, e.g. of 0.5-5 per cent strength.  If, during the caustic alkali treatment, the temperature is allowed to rise to 35 DEG  C. the mere cooling of the alkali lye to 15 DEG  C., after it has been removed at the end of the treatment, will cause alkali-metal nitrate to separate by crystallisation in an amount equivalent to the amount of nitric acid retained by the cellulose material at the end of the acid treatment.
