Patent FI-922734-A (FI)
Inventor: STENKVIST SVEN-EINAR
IPC: H05B7/18
Filed: 1992-06-12
Abstract: In direct-current arc furnace the arc is deflected in a direction away from the current supply means (19) through the action of the high-current lines (18) extending under the furnace vessel. This leads to the thermal overloading of a part of the furnace vessel walls. If the high-current lines (18a) are for the major part laid in a plane above the furnace bottom, on or below the furnace platform (20), and are taken downwards to the connection fittings (10) on the furnace bottom only on the side of the furnace vessel (1) opposite the current supply means, the arc will again burn symmetrically.

Abstract: Large format TV tubes must produce a high peak brightness in order to be acceptable to the user. This results in a large beam current in bright areas of the picture and in a subsequent defocusing of the resulting spot on the display and in a loss of the sharpness of vertical and horizontal transitions. The apparent sharpness of a vertical transition is gained by modifying the deflection of the TV receiver such that, at vertical transitions, the line on the bright side of the transition is deflected away from the transition region. Advantageously, the amount of vertical scan modulation corresponds to a multi-level control signal and depends on the grey levels of the transition.

Abstract: Liquid ring pumps with rotating liners supported by a bearing fluid (pressurized liquid or compressed gas) have a bearing fluid distribution system that compensates for the radially unsymmetric load on the rotating liner. If the liner bearing fluid is compressed gas, the axial ends of the liner may be either open and unsealed so that expended bearing gas escapes into the liquid ring in the pump, or the axial ends of the liner may be partly closed by radially inwardly extending end plates. Various mechanical and/or liquid seal structures may be used in conjunction with the end plates to seal the axial ends of the liner and/or to flush the clearances adjacent the axial ends of the liner.

Abstract: An ammonia-free reducer is added to cupric ions to achieve reduction to cuprous hydroxide in a process for the deposition of metallic copper on a catalytically activated surface by rapidly reducing cupric ions in aqueous solution to cuprous hydroxide, without substantial reduction to elemental or metallic copper, and thereafter effecting controlled disproportionation of the resultant cuprous hydroxide to bring about the deposition of metallic copper. The ammonia-free reducer is preferably hydroxylamine or its salts in the presence of a water soluble alkali metal- or alkaline earth metal- hydroxide, more preferably sodium hydroxide. The process of reduction of cupric ions is further effected by adding to the solution an antiagglomerating agent for controlling the dispersion of the cuprous hydroxide, preferably a polyol such as sorbose or invert sugar. The process of disproportionation of the cuprous hydroxide is further effected by adding an activator comprising a hydroxycarboxylic acid or salt thereof, preferably citric acid or malic acid with sulfuric acid, to bring about the deposition of metallic copper principally on the catalytically activated surface, wherein the hydroxycarboxylic acid or salt activator is present in solution in an amount no greater than about one mole per mole of cuprous hydroxide.

Filed: 1941-01-27
Abstract: 542,520. Silicon carbide. NORTON GRINDING WHEEL CO., Ltd. Jan. 27, 1941, No. 1064. Convention date, Jan. 26, 1940. Drawings to Specification. [Class 1 (ii)] [Also in Groups XXXV and XXXVI] A granular composition for use as a resistance in lightning arresters comprises 97 per cent. by weight silicon carbide and from .4 to 2.5 per cent of a reduction product of one or more of the oxides of aluminium, titanium, or zirconium (calculated as free metal). One method of production comprises the addition of the oxides to the usual charge in an electric furnace in stoichiometric proportions, the product being crushed into rounded grains and sifted to 40 to 120 mesh size. Another producing grains of carbide coated with the said reduction product which has penetrated partly into the grain, consists in roasting the grains in contact with the oxides in pulverized form, the coating being from 2 to 10 per cent. calculated as oxide. The process of manufacture does not reduce all the oxide, but is believed to produce a large amount of pure metal. The composition is free from uncombined silicon and free silica whereby clinkering when in use is avoided.

Title: Improvements in or relating to brake systems for tractor and trailer vehicle combinations
IPC: B60T11/10
Filed: 1946-01-11
Abstract: 600,949. Fluid-pressure brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and CHOUINGS, L. C. Jan. 11, 1946, No. 1081. [Class 103 (i)] A brake system for a tractor-trailer combination comprises a pedal-operated master cylinder 16 connected to slave cylinders operating the tractor brakes 13 and also to a valve 25 controlling a normally open byepass between a reservoir 24 and the output side of a pump 23 which is driven by the transmission and connected to the slave cylinders of the trailer brakes 21 by piping including a flexible hose 52 and quick-release couplings. Actuation of the master cylinder operates the valve 25 to restrict the byepass and thus cause pressure to build up and apply the trailer brakes. The valve, Fig. 2, comprises a body 33 formed with bores 34, 35 and a conical valve seat 36, the reservoir being connected to a port 26, the pump to a port 38 and the slave cylinders of the trailer to a port 27. Pressure-fluid from the master cylinder is admitted through a passage 48 and acts on a cup packing 46 to move a valve element 41 having a conical surface 42 co-operating with the valve seat 36. When the byepass is restricted, the pressure built up in the bore 35 reacts on the valve member so that the trailer brakes are applied in proportion to the amount of depression of the master cylinder pedal. The smaller end 44 of the valve member has a small clearance in the bore 35 to give a dash-pot action to damp the movements of the valve member. The tractor brake system may include a mechanical, hydraulic or pneumatic servomotor. The pump, reservoir and valve may be on the trailer, the pump being driven from the trailer wheels and the flexible hose provided in the connection between the master cylinder and valve. Specification 600,902 is referred to.

Abstract: 431,481. Ventilating mines. CARRIER ENGINEERING CO., Ltd., 24, Buckingham Gate, London.-(Lindsay, D. C. ; c/o Thompson & Co., Ltd., Johannesburg, South Africa) Jan. 11, 1934, No. 1134. [Class 137] A method of cooling and conditioning air in deep mines consists in discharging air so treated in one of lower levels of the mine into working passages at this level, and then passing it through passages at a higher level where it is mixed with air freshly conditioned at that level. The main, or downcast shaft 5 passes parallel to but beneath the gold bearing reef 6. Footwall drives 7a, 7<b>, 7<c> extend at right angles from the shaft 5, and cross cuts 8<a>, 8<b> and 8<c> extend into the reef. Various stopes 10<a>, 10<b>, 10<c> follow the reef from one reef drive 9<a>, 9<b>, 9<c> to another, the reef being honeycombed with stopes, the workings being in the form of an arrowhead pointing downwards. Air is drawn from the surface through shaft 5 into the lowest footwall drive, and is conditioned in a unit 11<a> in chamber 12<a> in cross cut 8<a>. A fan 14<a> draws air from shaft 5 through drives 7<a>, 8<a> and a portion passes through the conditioner and a portion is byepassed by damper 13<a>, its condition being thus controlled. The fan blows the air into reef drive 9<a> and upwards through stopes 10<a>, leading by stopes 10<b>, 10<c>, &c. to the surface, the space increasing at each higher succeeding level. To meet the increased requirements, a conditioner 11<b> is operated at the next level, drawing fresh air from shaft 5 through drive 7b and cross-cut 8<b>, this conditioned air being added to that from the lower level. A further conditioner 11<c> is shown operating in a similar manner. Thermostats 15<a>, 15<b> and 15<c> may be used to control the air temperature of the corresponding units. A part of the air from stopes 10<a> may be led through tunnel 16a into chamber 12b where it will be conditioned, mixed with untreated air from shaft 5, and discharged into reef drive 9<b> and stopes 10<b>. If desired, a mixture of air from any of the stopes with air from shaft 5 may be conditioned and passed into the shaft drives. It may be desirable to condition only re-circulated air, and allow fresh air to enter by infiltration or otherwise.

Abstract: 582,246. Inclinometers. PRICE, D. R., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Jan. 20,1944, Nos. 1164/44 and 4202/45. [Class 97 (ii)] [Also in Groups XXXVIII and XXXIX] A thermo-electric instrument (see Group XXXVIII) for use on ships, military tanks, aircraft, &c., utilizes the change of electric resistance produced in a wire by the variable cooling effects of air convection currents as the inclination of the wire is changed. As shown in Fig. 1, a nickel wire grid 4 heated through leads 5 is located in a mica chimney 3 supported within a metal casing 1 by means of wires 2. The air convection -currents set up vary in intensity as the inclination of the chimney varies and, by their cooling effect on the grid 4, vary its resistance and the current passing therethrough, the greatest rate of change occurring when the chimney is at about 30 degrees to the horizontal. In a modified arrangement the grids of two inclined chimneys are externally connected in push-pull circuit to give an enhanced response to tilting. In a further modification, Fig. 4, inclined grids in the form of helices 4a are arranged in closed tubes 9 within a casing 1c and are connected to a thermionic amplifier 11 and across a balancing resistance 10 fed with alternating or direct current. To give greater sensitivity to the instrument, the casing may be lined with copper thermally connected to an external heat radiator. False response of the instrument due to spinning may be minimised by locating the heated grid near the top of its enclosure. The device may be used for electric amplification (see Group XXXIX).

Abstract: 485,124. Turning -gear. HIRTHMOTOREN GES. Jan. 15, 1937, No. 1228. Convention date, Jan. 15, 1936. [Class 7 (v)] A starting-apparatus for aircraft or other engines consists of a starting and lighting dynamo-electric machine c, an auxiliary internal-combustion engine b, and clutching means for first enabling the machine c to start the engine b without driving the main engine a, then enabling the engine b and the parts rotating therewith to start the engine a, and finally enabling the engine a to drive the dynamoelectric machine. As shown in Fig. 1, the machine c comprises a field frame d fixed on the crank-shaft of the engine b and an armature f connected to the engine a through gearing o giving a different gear ratio according as the engine or the armature f is the driver. A friction clutch i is interposed between the armature f and the engine b. On closing a switch n supplying current to the machine c, the armature f is held stationary by the main engine and rotation of the field frame d starts the engine b. When the engine b is running under its own power, the machine c may supply current to a device s for heating the lubricating oil, the carburetter, or the air inlet of the main engine. The device s is then switched off, and the field frame d is allowed to attain a high speed of revolution and then connected by the clutch i through the gearing o to the main engine. When the latter starts, the clutch i is disengaged and the machine c is driven as a generator. In modifications, the field frame d is stationary, a disengageable clutch is interposed between the armature f and the engine b and an adjustable friction clutch between the gearing o and the armature f or the engine a. In a further modification, Fig. 4, a disc r coupled to the shaft of the auxiliary engine carries the field d and a coil u connected to slip rings, and the armature v carries an armature ring x for the coil u. When the auxiliary engine is being started, the coil u is without current and the field d acts as a flywheel. On supplying current to the coil u, the armature v is coupled to the field d by the magnetic field between the coil u and the ring x, and is set in rotation, so that its momentum is added to that of the parts d, r. A clutch q is provided between the gearing o and the main engine ; or the clutch may be electromagnetic and may connect the armature v to the gearing o by holding fast a planet pinion or a planet carrier.
