Abstract: Compounds having the general formula: <FORM:0969045/C1/1> wherein R3 and R4 are hydrogen, alkyl, aryl or hydroxyalkyl groups, are prepared by reacting 4-cyanoacetyl-aniline with cyanuric chloride and treating the product with an amine of the formula NHR3R4. Examples of this reaction are given wherein the amine used is methylamine, ethyl-, amine, n-propylamine, isopropylamine, n-butylamine, n-hexylamine, octylamine, dodecylamine, dimethylamine, diethylamine, diethanolamine, g -propanolamine, 4-amino -nbutanol, N-methyl-glucamine and aniline. Alternatively, cyanuric chloride is reacted with 2 molecular proportions of the amine and the product condensed with 4-cyanoacetyl-aniline. An example is given of reacting 2; 4-diamino -6- chloro -striazine with 4-cyanoacetyl-aniline.  2; 4-Bis -nbutylamine-6 [-41- (cyanomethylsulphonyl) anilino]-triazine is prepared by refluxing acetanilide -4- sulphinic acid with chloroacetonitrile in ethanolic KOH, and hydrolysing the product by refluxing in hydrochloric acid to give 4-(cyanomethylsulphonyl) aniline. This is then reacted with cyanuric chloride in acetone in the cold to give 2; 4-dichloro -6- [41-(cyanomethylsulphonyl) anilino] -triazine which is then reacted with n-butylamine. 4-N;N-Dicarboxyethylamino-benzaldehyde is obtained by reacting N;N-di(b -cyanoethyl) aniline with phosphorus oxychloride and N-methyl formanilide to introduce the aldehyde group, and the cyano groups are then hydrolysed to the acid with dilute alkali. The product is converted to its anil. Similarly, N;N-di(carboxymethyl) aniline is treated with phosphorous oxychloride and N-methyl formanilide and the free acid obtained by hydrolysis of the ester. The product may be converted into the anil by reaction with aniline.

Title: Method of controlling full load injection fuel injection particularly compression ignition engines using different fuels and apparatus for performing the same
IPC: F02D19/06
Filed: 1958-12-03
Abstract: 868,228. Regulating. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Dec. 3, 1958 [Dec. 5,1957], No. 38957/58. Class 7(6). The full-load delivery position of a fuel injection pump control rod is varied for different fuels by means responding to the density or viscosity of the fuel being used. In Fig. 1 the fuel is passed through a float chamber 8 containing a float 7 connected to an auxiliary stop 6. When a light fuel, such as petrol, is used the fullload delivery is fixed by a stop 4 but when diesel oil is used the float 7 rises to move the stop 6 in front of the stop 4 to limit the maximum delivery to a lower value. In a modification, Fig. 2, the float is replaced by a container 17, through which the fuel passes, carried by a pivoted arm 18 with a counterweight 20. The container, which is connected to the auxiliary stop 6, is positioned against an upper stop 21 when using light fuel, heavy fuel causing it to move down against a stop 22. The container may actuate the stop 6 through a solenoid. In Fig. 4 the auxiliary stop 6 is connected to a spring-loaded piston 35 in a chamber 34 connected in the fuel line 40 returning leakage fuel from the injectors to the fuel tank. When using light fuel a large amount escapes through pipe 40 and a restriction 42 therein produces a pressure build-up which depresses piston 35 to move the stop 6 away from stop 4. When using heavy fuel, very little fuel escapes through pipe 40 and no pressure build-up occurs so that the piston 35 positions the stop 6 in front of stop 4 to reduce the full-load delivery. In a modification, Fig. 5, the fuel flows to the engine through a clearance space around a piston 44 connected to the stop 6, a high viscosity fuel causing the piston to rise whereas a low viscosity fuel leaves it undisturbed.

IPC: G01G11/06
Filed: 1962-10-16
Abstract: 1,044,009. Endless conveyers. SIMONACCO Ltd. Sept. 27, 1963 [Oct. 16, 1962], No. 39061/62. Addition to 983,082. Heading B8A. [Also in Divisions G1 and G3] Apparatus for controlling the selective disposal of a variable mixture of solid materials, such as coal, comprises a conveyer belt 18 for the material and devices 128, 130, each having plates 138 which, when lowered divert the material to opposite sides of the conveyer belt. A number of resilient fingers 22 secured to a spindle 20 contact the surface of the material and the spindle is rotated an amount proportional to the mean depth of material across the belt. Rotation of the spindle adjusts the position of a valve member 44 which cooperates with a flexible seat 40 loaded by springs 46 52 to provide an outlet signal at 48, as described in Specification 722,993, proportional to the depth of material. The weight of material acts on an idler roller 56 against fluid.pressure in a chamber 62 which is adjusted by a valve 75 to provide a fluid pressure signal in conduit 71 proportional to the weight. The depth and weight signals are fed through conduits 126, 128 to two ratio controllers 80, 82. Each controller comprises two piston-cylinder devices 104 in which the cylinders are adjustably secured to a fixed member 105 and the pistons are adjustably secured to arms 86, 88 of a cruciform lever 84. One piston is subjected to the depth signal and the other to the weight signal whereby the lever 84 is rotated about a pivot 94 with variation in the differential of these signals to actuate a valve 100 controlling the supply and exhaust to a piston 134 of the devices 128, 130. The adjustment of the piston-cylinder devices provides diversion of the material to one side or the other of the conveyer when the differential in the pressure signals, i.e. the bulk density of the material falls below or exceed a predetermined range. With this range the material is carried along by the belt.

Abstract: 816,367. Zone-refining. WESTERN ELECTRIC CO. Inc. Dec. 18, 1957 [Dec. 27, 1956], No. 39372/57. Class 82(1) [Also in Group III] Electrically non-insulating materials such as Fe, Mo, Ti, Zr, W, Re, Bi, Ge and Si are zone-refined by passing through an ingot of the material, an electric current of sufficient magnitude to melt the material, the amount of melting being restricted to a small zone between two cooled portions at the extremities of the ingot, and movement of the molten zone being effected by varying the degree of cooling exercised by the two portions relative to each other. As Shown, an ingot of iron 1, is held between water cooled clamps 2 and 3 which are connected to a source of current 8 by connections 10 and 11. The molten zone 13 is moved along the ingot e.g. from left to right, by increasing the rate of cooling by clamp 2 and decreasing the rate of cooling by clamp 3. Modifications of the apparatus describe (i) a heat reflector surrounding the molten zone to reduce heat losses by radiation, (ii) additional cooling coils on either side of the molten zone which move with the zone and (iii) a device for allowing expansion of the ingot during heating; the ingot may be arranged with its longitudinal axis either vertical or horizontal in which latter case the molten zone is retained in position by interaction of the electric current and a magnetic field applied in a direction at right angles to that of the current. A theoretical treatment is included by which it is possible to calculate the temperatures required at the two cooling points to produce a molten zone of a desired length at a specific point in the ingot. Specifications 769,673, 774,270 and 810,448 are referred to.

Title: Method of depositing epitaxial semiconductor layers from the liquid phase
IPC: C30B19/00
Filed: 1972-08-31
Abstract: 1372124 Liquid phase epitaxy R C A CORPORATION 31 Aug 1972 [8 Dec 1971] 40342/72 Heading B1S An epitaxial layer of a semiconductor material is formed on a substrate by confining an area of the surface of the substrate for deposition by cooling a small spherical volume of a solution of the semiconductor material in contact with the surface so that the material is precipitated and applying a force, e.g. a weight to the non-contact surface of the charge to spread the charge into contact over all the confined area of the surface of the substrate. The solution applied to the substarte may be exactly saturated. Multiple layers may be deposited. As shown suitable apparatus 10, for forming the coated substrate comprises a furnace boat 12, e.g. of graphite, with three spaced wells 14, 16, and 18, in its upper surface and a passage 20 extending longitudinally through boat 12 across bottom wells 14, 16 and 18. The base of these wells is formed by the top surface of a slide 22 movable in a passage 20. The slide 22 has a pair of spaced recesses 24 and 26 in its top surface adjacent one end of the slide. The spacing of the recesses corresponds substantially to the spacing of adjacent wells. In the wells separate weights 28 and 30 corresponding substantially to the dimensions of the well and recesses are placed. To carry out this embodiment each of the wells is charged with a mixture of semiconductor material, e.g. gallium arsenide, a metal solvent for the semiconductor material, e.g. gallium, and optionally a conductivity modified such as tellurium or tin for an N-type layer or zinc, germanium or magnesium for a P-type layer. A body 32 of the same semiconductor material as in the wells is placed in recess 24, and a flat substrate 34 for liquid epitaxy coating placed in recess 26. The weights 28 and 30 are placed in position and the charged boat 12, placed in a furnace tube which is heated in hydrogen to above the melting temperature of the mixture to form solutions 36 and 38. The slide 22 is then moved to bring body 32 into contact with unsaturated solution 36 and when solution 36 is saturated the slide is moved until body 32 is in contact with solution 38 which becomes saturated. In this latter movement substrate 34 is brought into contact with saturated solution 36 and furnace heating is terminated. The resulting cooling deposits on substrate 34 a first epitaxial layer. A second layer is deposited by moving the slide to bring saturated solution 38 into contact with the coated substrate with further cooling of the boat, and the substrate with two epitaxial layers recovered. Other similar embodiments are described utilizing a second slide wherein the body of semiconductor material is mounted on the second slide and brought into contact with the desired solutions prior to moving a first slide containing the substrate into contact with the saturated solutions.
