Title: New pyridazines and process for their manufacture
IPC: C07D237/14
Filed: 1955-05-10
Abstract: The invention comprises 5-cyanopyridazines which contain in the 6-position an etherified hydroxyl group or an etherified mercapto group, particularly those which contain in the 3- and 4-positions alkyl groups of at most 5 carbon atoms, and a process for their preparation from 5-cyanopyridazines which possess a substituent in position 6 which is known to be convertible to an etherified hydroxyl or mercapto group, e.g. a halogen atom or a free hydroxyl or mercapto group.  In examples: (1) 6-chloro-5-cyano-3 : 4-dimethylpyridazine is treated with sodium in methanol to yield 6-methoxy-5-cyano-3 : 3-dimethylpyridazine; the corresponding 6-ethoxy- and 6-isopropoxy-derivatives are similarly prepared using ethanol and isopropanol respectively.  (2) 6-Mercapto-5-cyano-3 : 4-dimethylpyridazine is treated with caustic soda and dimethyl sulphate to give 6-methylmercapto-5-cyano-3 : 4-dimethylpyridazine. 6 - Chloro - 5 - cyano - 3 : 4 - dimethylpyridazine is prepared from the corresponding 6-hydroxy compound and phosphorus oxychloride.  6 - Mercapto - 5 - cyano - 3 : 4 - dimethylpyridazine is prepared by boiling the corresponding 6-chloro compound with thiourea in ethanol.ALSO:5-Cyano-pyridazines containing in the 6-position an etherified hydroxyl or etherified mercapto group and preferably alkyl groups in the 3- and 4-positions and which possess an analgesic action, are incorporated in pharmaceutical compositions suitable for external, parenteral or topical administration.  Specified carriers include gelatine, lactose, starches, magnesium stearate, talc, vegetable oils, benzyl alcohols, gums, polyalkylene glycols, petroleum jelly and cholesterol, together with auxiliary substances, e.g. preserving, stabilizing, wetting or emulsifying agents, buffers, salts for controlling osmotic pressure, and other therapeutics.

Abstract: 1,263,188. Grinding. HERMINGHAUSENWERKE G.m.b.H. 14 March, 1969 [14 March, 1968], No. 13669/69. Heading B3D. A centreless grinder comprises a machine bed 1, a grinding-wheel 6 rotatably mounted in a headstock 2, a regulating wheel 7 rotatably mounted in a headstock 3, which is mounted directly or indirectly on the bed 1 for sliding movement toward or away from the wheel 6, a workpiece holder 4 mounted directly or indirectly on the bed 1, and means operative during grinding for driving across the bed 1 in a controlled manner and at a predetermined rate the headstock 3 and either the headstock 2 or the holder 4 in such a manner as to cause relative movement between both the wheel 6 and holder 4, and between holder 4 and wheel 7, so as to cause the axis of the workpiece 8 to shift progressively relative to the holder 4 towards the wheel 6 during grinding and thus prevent the wheel 6 from coming into contact with the holder 4.

Title: Method of measuring torque
IPC: G01L3/24
Filed: 1972-03-23
Abstract: 1391790 Measuring acceleration and torque electrically ROTODYNE INC 23 March 1972 [7 April 1971] 13689/72 Heading G1N A method of measuring torque, especially applicable to motor vehicles, comprises measuring angular acceleration and combining the resulting signal with signals indicative of inertia to obtain a measure of torque. If N A  = torque produced by engine; N B  = torque associated with internal friction; N C  = torque associated with external load; I a  = moment of inertia of engine system; I b  = moment of inertia of drive wheel system; W a  = angular velocity of engine; W b  = angular velocity of wheels; α a  = angular acceleration of engine; α b  = angular acceleration of wheels;  Then, since #Iα = #N, I a α a  + I b α b  = N A  + N B  + N C  and NA can be determined if the other elements are determined or known. As shown in Fig. 1 a tachometer generator measures W producing a signal V w  which is differentiated to give V α . V w  is also compared at 30 with a signal V o  indicative of a predetermined speed W o . At equality a signal G causes the value Vα (viz V αo ) to be sampled and stored at 34. Circuit 38 multiplies V αo  with a signal indicative of the inertia I, and circuit 44 subtracts from this a preset signal L indicative of known internal and external losses, providing an indication of torque at 50. By multiplying this signal with V o  an indication of power is provided. N B  and N C  may be eliminated by taking measurements with increasing and decreasing accelerations about the preset speed. Let (KI a  + I b )α b1  = N A1  + N B  + N C  apply to acceleration. If the foot is removed from the accelerator with the vehicle in gear, the driving torque is a known quantity N AZ  (which is approximately zero). Under these conditions (KI a  + I b ) α b2  = N A2  + N B  + N C . Subtracting these two equations N B  + N C  can be eliminated, the necessary circuit being disclosed in Fig.2 (not shown). Fig.3 (not shown) discloses a modified circuit producing an output indicating power.

Title: Improved process for the disintegration of proteins
IPC: A23J3/34
Filed: 1954-05-11
Abstract: A process for the disintegration of proteins without formation of ammonia and urea and secondary fermentations, comprises adding a mixture of ethyl salicylate and a terpene, which may be previously oxidized by perbenzoic acid, nascent or molecular oxygen, or ozone, e.g. essence of pine or turpentine, to the reaction mixture prior to the disintegration.  The reaction is effected by heating the mixture of pulped protein-containing material, e.g. flesh, blood, fish, and the protective substances, at 35 DEG  to 55 DEG  C. and pH 6.4 to 7. The resulting solution is separated from the solid residue of undigested substances, freed from traces of protective substances by concentration in vacuo to a density greater than 1.09, cleared by defecation, e.g. with an aqueous solution of tannin in ether, and the filtered solution freed from ammonia by agitation with magnesia.  The produce may be further concentrated to a crystal paste or dry solid. If the starting material does not contain autolysable organic material, that is, diastases, e.g. bromelin, papain, pepsin, trypsin, pancreatin or foreign diastases in the form of decomposed autolysable materials, these substances are added after the addition of the protective substances.  The protective substance may consist of 1 gram of essence of turpentine and 2.5 grams ethyl salicylate per kilogram of starting material.  Adjustment of pH is effected by addition of acetic or lactic acid, or trisodium phosphate.  The treatment of blood necessitates the addition of an anti-coagulant, e.g. sodium citrate, crushing and h molysing, e.g. with diethyl ether, and addition of a mixture of sugar and plasmolysed fresh yeast prior to the addition of the protective agents.
