Title: Improvements in and relating to radio direction finding apparatus
IPC: G01S3/06
Filed: 1955-06-27
Abstract: 777,404. Radio direction finding. STEWART-WARNER CORPORATION. June 27, 1955 [July 12, 1954], No. 18530/55. Class 40(7) When a radio direction finding aerial system is mounted with at least the sense aerial on top of a mast, as is commonly the case on ships, errors arise in the direction indications obtained at differing frequencies due to electrical resonance of the mast. To compensate for such errors a length of co-axial cable cut to counterbalance the effect of the mast is provided and its outer conductor connected to the top of the mast. The inner conductor is electrically connected to the sense aerial and the other end of the coaxial cable left open. A suitable arrangement is shown in Fig. 4 wherein the loop and vertical sense aerial are shown both mounted on top of a mast and interconnected by a tuner unit T. The co-axial cable is adjusted to resonate as a half-wave resonator at the same frequency as the mast resonates as a half-wave resonator. This ensures the correct phase relationship and a resistor (e.g. R2) is arranged in series with the inner conductor of the cable to give the correct amplitude. As the amplitude of the mast voltage resonances and cable voltage resonances may not be balanced for frequencies of use causing resonances in several differing modes a choice of values of resistor may be required. In this case a selector switch S1 is included selecting resistors R1, R2, or R3 and controlled by connection'with the frequency selector F on the receiver R. The same selector may also control turret tuning means in tuner unit T. Where tuning over a wide range is required the electrical length of the mast may not bear a linear relationship to wavelength and it may be necssary to use different compensating co-axial cables for different parts of the frequency range (Fig. 5, not shown). In an extreme case a selection of series resistors may be required for each such cable and the various cable and resistor selecting switches can be all controlled from the receiver frequency selector (Fig. 6, not shown). The aerial system may be housed in a dome on top of the mast.

Filed: 1948-07-09
Abstract: 649,015. Moulding and shaping glass plates, BEAVEN, R. J., and CARTER, D. C. July 9, 1948, No. 18556. [Class 56] A plate glass correcting plate for an optical projection system (e.g. for correcting observation in a television receiver) is formed by applying the glass plate to a mould, preferably of metal or ceramic and ground or otherwise formed to the required aspheric figure of revolution, and uniformly heating the assembly till the glass subsides and conforms to the mould, the upper surface having the required contour, cooling the glass and grinding and optically polishing the back surface flat, the glass and mould co-operation being such that the finished plate has means for ensuring that it can be accurately centred in the optical system. The centre point in the mould may be formed by a dowel, or a tiny spike or pip, or a tiny depression, and the glass has a circular orifice to fit accurately on the dowel pin, or has a tiny depression to fit the spike or pip, or is left flat. Any distortion at or near the periphery is cut away. When the glass has a central orifice the cathode ray tube fits into this orifice so that the plate and the tube have the same optical axis. In an example giving the dimensions of the glass, the glass is first heated to 400‹C. with its edge resting on the mould at one point only and supported at the diametrally opposite point by a temporary block which is then removed so that the hole in the glass engages the dowel, and then heated till the glass is plastic and moulded, cooled slowly to 500‹C., trimmed, and the back surface ground. Specification 3444/09, [Class 56], is referred to.

Patent GB-751860-A (GB)
Title: Grease compositions
Filed: 1953-07-13
Abstract: A grease composition exhibiting high stability at elevated temperatures comprises a lubricating oil base, an inorganic gelling agent in sufficient quantity to thicken the lubricating oil base to a grease consistency, a hydrogen donor (i.e. a mono -, di - or poly - cyclic hydrocarbon, or substitution product thereof, which is capable of splitting off hydrogen at temperatures above 300 DEG F. in the presence of a hydrogen transfer catalyst and a substance capable of being reduced) and a hydrogen transfer catalyst.  The lubricating oil base may be a mineral oil or a synthetic oil such as an ester or an aliphatic polyether. Suitable ester lubricating oils are those derived from carboxylic acids, acids of phosphorus and silicic acid, particularly dialkyl esters of dicarboxylic acids, organic phosphates, phosphonates, phosphinates and the corresponding phosphine oxides. tetra-alklyl silicates and thia-alkyl silicates. Suitable aliphatic polyether lubricating oils comprise polyalkylene oxides and polyalkylene glycols wherein either or both end hydroxyl groups may be esterified or etherified.  The inorganic gelling agent may be silica, particularly in aerogel form, magnesia, lime, surface-esterified silica, clay or orium clay.  The hydrogen donor may be an aromatic or cyclo-aliphatic hydrocarbon, for example a naphthene.  The specified hydrogen donors include alkylated naphthalenes, alkylated cyclohexanes, unsaturated cycloaliphatic hydrocarbons, and hydrogenated aromatic compounds.  Where a mineral lubricating oil is employed which contains naphthenes, for example a bright stock or cylinder oil, the separate addition of a hydrogen donor is unnecessary.  Suitable hydrogen transfer catalysts are silica-alumina, silicaboron trioxide, silica-zirconia-alumina, silica-alumina-magnesia-boron trioxide, chromium sesquioxide-alumina, activated clays, zinc oxide and inorganic zinc salts such as zinc carbonate.  The hydrogen transfer catalyst may function solely in its capacity of a hydrogen transfer cotalyst or may also act as a gelling agent. Thus, the hydrogen transfer catalyst may be present in the grease in addition to the gelling agent, may partially replace the gelling agent, or may even constitute the sole gelling agent. The grease composition may contain additional ingredients such as antioxidants (e.g. aromatic amines, phenolic materials, and epoxy compounds), metallic sulphides, and surface-active agents (e.g. high molecular weight amines and partial amides).  In the examples, grease compositions are described consisting of naphthlene-containing bright stock, silica aerogel and zinc oxide, alumina, alumina-boron trioxide, or zinc carbonate.

Title: Improvements in the recovery of nitrate of soda from solutions containing it
IPC: C01D9/02
Filed: 1919-08-06
Abstract: 153,649. Hobsbawn, J. B., (Grigioni, J. L.). Aug. 6, 1919. Sodium nitrate is obtained from its solution by first separating a considerable proportion of the sulphates and chlorides present by concentration under an absolute pressure of 11 lb. per sq. in. until a temperature of 90-95‹ C. is reached, and afterwards concentrating the liquor at atmospheric or other pressure until the content of chloride (calculated as the sodium salt) is 75-80 gm. per litre. The concentrated liquor is then cooled for the production of sodium nitrate crystals. The first stage of the concentration is effected in a vacuum evaporator consisting of a heater 3 and a separator 7 connected by circulating pipes 6, 9. The crystals of chloride and sulphate that separate are discharged through a valve 11 into a settling tank 12 from which they are removed by conveyers 17, 19. The crystals may be washed by liquor from the store tank 1. A pump 2 feeds liquor from the store tank 1 to the heater 3, and a pump 21 returns liquor from the settling tank 12 to the heater. The second stage of the concentration is effected in an intermittently-working evaporator consisting of a heater 23 and a separator 24 operating under a pressure such that the steam generated may be led by a pipe 4 to the heater 3 and used as heating-agent therein. The evaporator 23, 24 is filled by adjusting a valve 22 so as to permit a portion of the liquor from the pump 21 to enter the heater 23. When the liquor has reached the prescribed concentration, the contents of the evaporator 23, 24 are discharged through a filter 29 and are pumped into a chamber 32 maintained under an absolute pressure of 12-13 lb. per sq. in., and are cooled to 70-75‹ C. by evaporation under the reduced pressure. The liquor is then transferred to a rotary cooler 37, in which the sodium-nitrate separates.

Title: A method of and means for detecting the presence in or absence from bodies of non-magnetic material of certain component bodies of magnetic material
IPC: G01V3/08
Filed: 1920-07-08
Abstract: 164,977. Jackson, G. H. July 8, 1920. Magnetic tests.-The presence in or absence from a body of non-magnetic material, for example, a fuse, of a body of magnetic material, for example, a shearing-pin, is determined by supporting the body to be tested in a magnetic field in such a manner that the supporting-means and the field are capable of relative movement. In the arrangement shown, for testing a fuse, the fuse is placed on a table 12 rotatably mounted between the pole-pieces 25 of an electromagnet 24, which is itself rotatable about the same axis as the table. If the shearing-pin is present and out of alignment with the poles, the table rotates until the pin is in alignment with the poles. If no movement takes place the elctromagnet may b rotated, whereupon the table follows the movement if the pin is present. Either the table or the electromagnet may be fixed. The polepieces 25 may be removable or adjustable, or a permanent magnet may be used instead of an electromagnet. In a modification, the magnet is replaced by coils supplied with three-phase current to produce a rotating magnet field. Ii the magnetic component is present the body to be tested follows the rotation of the field.
