Filed: 1959-09-16
Abstract: The invention comprises tris(dialkylaminoalkyl) phosphates having the general formula <FORM:0891413/IV (b)/1> in which R1 and R2 are C1-C4 alkyl groups, A is a divalent saturated alkylene chain having 2 to 6 carbon atoms, the nitrogen and oxygen atoms being separated by a chain of at least 2 carbon atoms, and non-toxic acid addition salts thereof.  The free bases may be obtained by reacting one molecular proportion of phosphorus oxychloride with at least 6 molecular proportions of an alkanolamine (R1)(R2)N.A.OH in solution in an organic solvent.  The phosphorus oxychloride is suitably added to the alkanolamine, with cooling, at such a rate so as to maintain the temperature at 0 DEG C.-10 DEG C. and the solution is then stirred at about 20 DEG C. to 50 DEG C. and allowed to stand until reaction is complete.  The acid addition salts may be obtained by reacting the base with a stoichiometric amount of a suitable organic or inorganic acid in an aqueous miscible solvent, e.g., acetone or ethanol, or with an excess of the acid in an aqueous immiscible solvent such as ethyl ether or chloroform.  Specified acids are maleic, fumaric, benzoic, ethanedisulphonic, citric, lactic, benzene sulphonic, methane sulphonic, acetic, tartaric, succinic, hydrochloric, hydrobromic, sulphuric, nitric, phosphoric, and sulphamic acids. Examples are given for the preparation of tris(b -dimethyl-aminoethyl) phosphate and its trihydrochloride, tris-(b -dimethylaminoisopropyl) phosphate and its maleate salt, tris-(b -di-methylaminohexyl) phosphate and its citrate salt, and tris-(b -dibutylaminoethyl) phosphate and its tri-hydrobromide. The products are useful as anti-hypercholester olemic agents (see Group VI].ALSO:A pharmaceutical composition having antihypercholesterolemic activity comprises a tris(dialkylaminoalkyl) phosphate having the formula <FORM:0891413/VI/1> in which R1 and R2 are C1-C4 alkyl groups and A is a divalent saturated alkylene chain containing 2 to 6 carbon atoms, the nitrogen and oxygen atoms being separated by a chain of at least two carbon atoms, or a non-toxic acid addition salt thereof (see Group IV (b)) and a pharmaceutical carrier.

Title: Improvements in processes and apparatus for the mechanical kneading of dough
IPC: A21C7/00
Filed: 1930-10-27
Abstract: 368,357. Rolling-up and rounding dough. KREMMLING, L., Hamersleben, near Oschersleben, Bode, Germany. Oct. 27, 1930, No. 32261. Convention date, Oct. 26, 1929. [Class 87 (ii).] In the mechanical kneading of pieces of dough, the pieces are first kneaded in a cell with circular orbital kneading motion and then in a cell of different horizontal cross section with a reciprocating kneading motion. The second kneading may be effected in the same cell which is altered by withdrawing partition walls or by distorting a resilient cell. As shown in Figs. 1 and 2, the dough is kneaded in a square cell having removable partition walls 3, 4 connected with a head 5 so that during the reciprocating kneading an elongated somewhat hexagonal cell is used. A number of such cells may be combined into a kneading head having withdrawable partitions mounted upon a common operating member and variable upper walls or pressure plates also mounted for simultaneous adjustment. Where a yielding cell 6, Figs. 3 and 4, is employed, the upper wall may consist of a flexible sheet resting on the cell and connected to the frame for stretching and actuating the kneading cell. Fig. 6 shows mechanism for producing the circular and reciprocating kneading motions, the main drive shaft 27 being connected by a crank pin 29 to swinging arms 32, 42 having slots 35, 45 along which blocks 37, 47 are adjustable. These blocks are connected to the kneading head 40 and the character of the kneading motion depends upon the adjustments of the blocks 37, 47. In a modified mechanism, the links 38, 48 are actuated by a crank having an adjustable throw, the adjustment being effected by mounting the crank upon a bell-crank lever and connecting it to an adjusting shaft slidable in the main crank shaft. The walls of the kneading cells could be arranged to telescope within one another in a direction parallel to the plane of kneading, or the walls could be hinged together to permit variation of the sectional form. Specification 270,304, [Class 87 (ii), Moulding plastic &c. substances], is referred to.

Abstract: 1481109 Condensers NOVEX TALALMANYFEJLESZTO ES ERTEKESITO KULKERESKEDELMI RT 23 July 1974 [25 July 1973] 32478/74 Heading F4S A system for the regulation of cooling water supply to a condenser 8 comprises a first pumpstage 2 of variable output disposed between a cooling water storage device 1 (e.g. a reservoir stream of lake) and a cooling water duct 31 which latter is coupled on the one hand to a second pumping stage 7 and on the other hand to a drainage duct 11, 11a via a permanently open connecting duct 5, the condenser being connected to receive the output of the second pumping stage 7, and the drainage duct 11, 11a connecting the condenser to a receiving vessel 10 for warmed water from the condenser by way of an overflow device of sluice 91. The arrangement may utilize, as shown, a system of freewater levels, or it may comprise a generally closed system operating under pressure (Fig. 2). In normal operation with both pumping stages operative and Q 1 <Q 2 , some of the cooling water from the reservoir 91 will flow through the duct 5 direction (#Q 1 ) bypassing the condenser and flowing via the line 11a and to the receptacle 10 for warmed water. If Q<Q 2  some of the warmed water passing to the vessel 61 from the condenser 8 via duct 11 will be recirculated to the condenser via the duct 5 (direction #Q 2 ) so that any desired increase or decrease in the temperature of the cooling water suppled to the condenser can be achieved by providing a difference in the water delivery Q 1 , Q 2  of the two pumping stages by regulating the delivery Q 1  of pumping stage 2. When Q=Q 2  there is substantially no flow through the connecting duct 5. If, e.g. due to pump failure only the pumping stage 7 is operative, an essentially closed-circuit water flow through the condenser 8 will be maintained via line 11, vessel 61, ducts 5 and 31 and container 12. If only the pumping stage 2 is operating, water from the reservoir 1 will circulate via the duct 5 to the receptacle 10 without passing through the condenser.
