Filed: 1961-08-18
Abstract: The invention comprises compounds of the formula: <FORM:0949725/C2/1> (wherein R1 is a C1-6 alkanoyl group, R2 is hydrogen or a C1-6 alkanoyl group, and R3 is a C1-5 alkyl group) the preparation of the N, O, O-triacylates by reacting the free aminodiol with an excess of the appropriate alkanoic anhydride or alkanoyl halide in the presence of an organic base, and the preparation of the O, O-diacylates by gradually adding an excess of the appropriate alkanoic anhydride to a solution of the free amino-diol in dilute alkali the amount of alkali present being such that it stoichiometrically balances at least 85% but not over 100% of the amount of potential acids used in the form of anhydride. To prepare formyl derivatives a mixed anhydride of formic and acetic acids is used. Examples are given. Alpha - ethyl - beta -(3, 4-dihydroxyphenyl)-alanine is prepared by reacting 3, 4-dimethoxy-phenylacetonitrile with ethyl propionate in presence of sodium ethoxide to give 1-(3,4-dimethoxyphenyl) -1- cyano - butanone -2 (via its sodium salt), heating this with sulphuric acid to give 1-(3,4-dimethoxyphenyl)-butanone-2, reacting this with potassium cyanide and ammonium carbonate in aqueous ethanol to give 5-ethyl -5- (3,4-dimethoxybenzyl)-hydantoin, hydrolysing this with barium hydroxide to give alpha-ethyl-beta-(3,4-dimethoxyphenyl)-alanine, and heating this with hydrobromic acid. Other alpha-alkyl-beta-(3,4-dihydroxyphenyl)-alanines are prepared similarly, substituting other ethyl alkanoates for the ethyl propionate used in the first stage of the above synthesis. The compounds of the invention, which are stated to have anti-hypertensive properties, may be formulated as tablets with conventional ingredients. Specifications 936,074, 945,892, 945,893 and U.S.A.

Patent ES-373970-A1 (ES)
Title: Mechanism for controlling flow of liquid to a vacuum-treating vessel
IPC: C21C7/10
Filed: 1969-11-27
Abstract: The flow of molten steel from the bottom outlet 20 of a tundish 12 into the inlet 15 of a vacuum degassing vessel 10 beneath it, is selectively prevented or allowed by the interposition of slidable gates therebetween, the gates either being solid or having nozzle apertures extending therethrough. The gates are slid into sealing engagement with the tundish 12 and a spring urged inlet seal member 23 of the vessel 10, into alignment with the openings 20, 15 by a reciprocable ram 33 carried on the vessel 10 thereby knocking away a gate already positioned between them. A number of the gates are carried on a tray 36 reciprocable transversely of the ram 33 by means of a driven rack 37, to bring each gate when required into alignment with ram 33. To allow tundish 12 to be removed from vessel 10 without destroying the vacuum in the latter, a gate 47 composed of separable upper and lower parts is interposed between them by ram 33. Flanges (not shown) on the separable upper part engage between beveled guide bars 52, 54 provided on the tundish, below its outlet opening 20 so that the separable upper part is lifted away with the tundish and seals off its outlet 20 when the tundish is removed from the vessel. The lower part of the gate 47 remains in position over the inlet seal member 23, being drawn against it by the vacuum, and so retains the vacuum in the vessel 10.

Title: Cocoa powder stabilizing/tempering method - in hermetically sealed vat,with air assisted stirrer
IPC: A23G1/04
Filed: 1971-04-19
Abstract: Milled cocoa powder is cooled in a hermetically sealed vat in which it is stabilised and treated. The cylindrical vat which has a truncated coneshaped bottom has a compressed air supply connection feeding upwards through a perforated bottom plate into the vat, creating a turbulance which is assisted by a motor driven vertical stirrer, provided with rightangled concave agitator blades. The stabilised cocoa powder leaves through an overflow pipe into a multi- way metering valve for consequent sack filling. Excess air with any entrained cocoa particles leaves the vat through a top mounted valve into a dry separator, from where the cocoa is recycled.

Patent ES-439353-A1 (ES)
Title: Axial flow fan with adjustable blades
IPC: F04D29/36
Filed: 1975-07-12
Abstract: An axial flow fan wherein the cylindrical housings for the shanks of blades are mounted on a flat plate-like circular base of the hub which is rotated by an electric motor through the medium of a belt transmission and a hollow shaft. The motor, transmission and shaft are mounted at one side and the housings are mounted at the other side of the base. The shanks of the blades are turnable simultaneously by a mechanism which has a rod-like pusher extending axially through the base, a double-acting hydraulic or pneumatic cylinder whose piston is rigid with and can move the pusher axially, a displacing disk attached to that end of the pusher which is nearer to the housings, a lever rigidly affixed to each shank, and discrete linkages coupling the disk with each lever so that the levers rotate the respective shanks and blades simultaneously clockwise when the piston moves the pusher axially in one direction and that the levers rotate the respective shanks and blades simultaneously counterclockwise when the piston moves the pusher axially in the other direction. A sleeve on the base supports tie rods which confine the disk to movements in the axial direction of the hub. Alternatively, the sleeve can be omitted and the cylinder can be mounted on the base in a position to support the tie rods. If the cylinder rotates with the hub, the pusher has concentric channels which connect the cylinder chambers with a source of pressurized fluid. The channels can be omitted if the cylinder need not rotate with the hub the cylinder chambers are then directly connected with the source of pressurized fluid by suitable conduits.

Title: Ceramic tile feed to packing boxes - has computer holding tiles in buffer stores according to grade
IPC: B65B57/14
Filed: 1976-12-22
Abstract: The system assembles, separates and feeds to packing boxes ceramic tiles previously graded for quality by a computer. The speed of the conveyor for the tiles already graded is regulated so that the distance between adjacent tiles is sufficient to allow insertion of one or more. The separately selected tiles are removed under control of the computer and held in buffer store units until a number has accumulated in each sufficient to fill a box completely. The tiles from a store unit are then inserted in the intervals between incoming tiles of the same grade, and when processing of a batch of this grade is complete a changeover is made to another one. The computer halts the grading unit temporarily if one of the store units can take no more tiles in, and stops the complete conveyor if all are simultaneously full up.

Title: Average beam current limiter
IPC: H04N5/59
Filed: 1978-05-05
Abstract: An average beam current limiter for a kinescope responsive to video signals coupled to the kinescope via a signal transmission channel comprises a source of control signals representative of average current drawn by the kinescope. When average beam current exceeds a predetermined threshold level by an amount within a first range of beam current, a corresponding control signal is coupled to the signal transmission channel to vary the D.C. content of the video signal in a direction to limit beam current above the threshold level within the first range. When beam current exceeds the threshold level by a relatively greater amount within a second range of current, a corresponding control signal serves to vary the peak amplitude of the video signal to limit beam current within the second range.

Title: Fuel/Air Ratio Control of an Internal Combustion Engine using a Fuel Containing Partially Oxygenated Hydrocarbon
IPC: F02D19/08
Filed: 1979-01-11
Abstract: The fuel/air ratio of a mixture of air and a fuel containing petrol and a substantial portion of partially oxygenated hydrocarbons, for example ethanol or methanol, is maintained at or close to stoichiometric by a closed loop control. The control includes an oxygen sensor 14 in the exhaust from the combustion chamber 10 which provides a state signal E1 indicating whether burning is below or above stoichiometric. The state signal is processed by an air-to-fuel ratio control circuit 22 to provide a control signal E2 that biases an air-to-fuel ratio control mechanism 20 in a direction that maintains the air-to-fuel ratio within a very narrow band around stoichiometric. A three-way catalyst is employed to minimize the pollution output from this internal combustion system and because of the closed loop control, the catalyst's effectiveness is optimized.
