Title: Signal level determining apparatus and method
Inventor: SZAJNOWSKI WIESLAW JERZY
IPC: G01S7/292
Filed: 2008-05-20
Abstract: An apparatus and method is disclosed for detecting a signal in the presence of background noise which includes impulsive noise. Each value of a signal is mapped to a point on a semicircle defined by two coordinates on orthogonal axes in two-dimensional space. A respective mean is calculated of each of the two coordinates of the transformed points, and the two means are used to calculate a detection threshold representative of the concentration of the points on the semicircle. A mean of the signal values is calculated and compared against the detection threshold. Alternatively, the mean is adjusted in dependence upon the concentration of the points on the semicircle and the adjusted mean is compared against a fixed threshold value. The apparatus is particularly suited to detecting a signal reflected from a small object in the presence of interfering signals backscattered by a dynamically disturbed sea surface.

Title: Improvements in formulations containing amine salts of polychlorophenoxyacetic acids
IPC: C07C59/70
Filed: 1951-04-30
Abstract: Herbicides comprising amine salts of polychlorophenoxyacetic acids are rendered capable of dilution with hard water without the formation of objectionable precipitates by incorporating therein a tribasic amine citrate of formula <FORM:0697686/VI/1> where X, Y and Z are each selected from hydrogen, alkyl and hydroxyalkyl containing 1 to 6 carbon atoms, not more than two, and preferably not more than one, of the three groups X, Y and Z being hydrogen.  Preferred polychloro-derivatives are 2,4-dichlorophenoxyacetic acid, 2,4,5-trichlorophenoxyacetic acid and mixtures thereof.  The amines used in the preparation of the salts are of the same general formul as those used for the preparation of the tri-basic amine citrate. Typical examples are those in which X, Y and Z are methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, tertiary butyl, beta hydroxyethyl, gamma hydroxypropyl and beta-hydroxyisopropyl.  The compositions may be aqueous concentrates containing 20 to 50 per cent of the polychlorophenoxyacetic acid, or dry compositions containing at least 50 per cent, and preferably 75 per cent, of the acid. Preformed amine salt may be mixed with the preformed tri-basic amine citrate.  Alternatively the amine, or mixture of amines, may be added to the polychlorophenoxyacetic acid and citric acid in water to a pH 7 to 9.  A powder is obtained by drying such a solution.  The citric acid is preferably 2 to 15 per cent of the polychlorophenoxyacetic acid.  Triammonium citrate may be used in place of the tri-basic amine citrate.  Solubilizers such as methyl alcohol and ethyl alcohol, and wetting agents may also be present.  In examples the following amines are used: - methylamine, dimethylamine, ethylamine, diethylamine, triethylamine, isopropylamine, diethanolamine, triethanolamine, isopropanolamine, diisopropanolamine and triisopropanolamine.

Title: Manufacture of aniline-sulphonic acids
IPC: C07C309/45
Filed: 1931-04-07
Abstract: Primary aromatic amines wherein both m-positions and one of the o or p-positions are substituted by alkyl, o-alkyl, nitro, sulphonic acid, carboxylic acid groups or halogen, one of the o- or p-positions is unsubstituted and the remaining position unsubstituted or substituted by alkyl, o-alkyl, nitro, sulphonic acid, carboxylic acid groups or halogen is sulphonated with an equimolecular proportion of a halogen sulphonic acid advantageously in the presence of a diluent, moisture being excluded.  The sulphonic group enters the p-position to the amino group if the position is unsubstituted otherwise it enters the o-position.  In examples (1) 4 : 6-dichloro-2-amino-1 : 3-xylene is sulphonated with chlorsulphonic acid to yield the 5-sulphonic acid; (2) 2 : 6-dichloro-4-amino-1-toluene yields the 3-sulphonic acid; (3) chloropseudocumidine (3-chloro-2 : 4 : 5-trimethylaniline) yields the 6-sulphonic acid; (4) bromoxylidine (2-bromo-3 : 5-dimethylaniline) yields the 4-sulphonic acid. Similarly, 3 : 4 : 5-trichloro-1-aminobenzene yields the 2-sulphonic acid, 2 : 4-dimethyl-3 : 5-dichloro-1-aminobenzene yields the 6-sulphonic acid, 2-methoxy-3 : 5-dichloro-1-aminobenzene yields the 4-sulphonic acid, 3 : 4-dimethyl-5-nitro-1-aminobenzene yields the 2-sulphonic acid, 3 : 5-dichloraniline-4-sulphonic acid yields the 2 : 4-disulphonic acid and 3 : 5-dichloro-4-carboxy-1-amino-benzene yields the 2-sulphonic acid.  Other halogen sulphonic acids such as fluorosulphonic acid may be used in place of the chlorsulphonic acid used in the examples. Specification 175,019, [Class 2 (iii), Dyes &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the sulphonation of primary aromatic amines wherein both the o-position and the p-position to the amino group are unsubstituted, the sulphonation of symmetrical m-xylidine (1-amino-3 : 5-dimethylbenzene) with chlorsulphonic acid to give the 4-sulphonic acid and the sulphonation of 3 : 5-dichloro-1-aminobenzene and 3-methoxy-5-chloro-1-aminobenzene to give the 4-sulphonic acids being described.  This subject-matter does not appear in the Specification as accepted.

Abstract: 599,925. Casting-machines. COOKE, C. March 27, 1946, No. 10460/45. [Class 83 (i)] Casting processes ; moulds ; clamping moulds.-In apparatus for casting metals under pressure and having means for the controlled heating of the wall of the mould container, the pressure in the container is regulated by an adjustable one-way valve permitting excess pressure to escape to atmosphere. A base-plate 10 carries a vertical pillar 11, Fig. 1, on which is clamped an adjustable arm 13, and is formed with a recess 15 to receive a flanged plate 16 and sealing disc 17. The mould container 19 is clamped between the disc 17 and an annular sealing ring 26 in a recess of a cover 24 carried by a post 29 which may be vertically adjusted within a bush 37 of the arm 13 by means of a handle 41 and clamped by a screw 43. In a modified form, Fig. 2, the members 16 and 24 carry adaptors 20 and 56 respectively designed to accommodate a smaller mould container 21. The lower end of the post 29 is formed with an annular gas passage connected to a gas supply pipe 33 and with a central air supply nozzle 30 connected to an air supply pipe 35. Around the mould container is a cylindrical casing 44 containing a gas ring 46 for heating the mould externally. The cover 24 carries a tube 52 through which the interior of the mould container may be vented to atmosphere under the control of an adjustable relief valve 53. In operation, the mould 57 in the container19 or 21 is placed on the apparatus and the gas ring 46 is ignited slowly to dry and heat the mould to the temperature required for the casting operation. The blast pipe flame at the end of'the post 29 is ignited, the metal to be cast is placed in the runner cup 58, the cover 24 is lowered on to the container and the metal is melted by the combined heat of the gas ring 46 and blast pipe flame. Alternatively, molten metal may be poured into the mould before the cover 24 is lowered on to the container. Pressure within the container builds up by reason of the supply of air and gas by the pipes 33 and 35 and operates a non-return valve 8 to cut off the gas supply, the air pressure being increased up to the value determined by the pre-set relief valve 53. The rate of cooling of the casting is controlled by means of the gas ring 46.
