Title: Pharmaceutically - active extracts from plants of the genus
Inventor: IWASE JONZE
IPC: A61K36/505
Filed: 1965-10-20
Abstract: A pharmaceutically active substance, suitable for the treatment of peptic ulcer, is prepared from tubers of plants of the genus Corydalis by extracting with a polar solvent, concentrating and acidifying the extract, defatting, making the defatted solution alkaline, extracting with a water immiscible solvent capable of forming hydrogen bonds, and separating the active substance from the non-polar solvent.  The preferred plant is Corydalis bulbosa, D.C. (also known as C. cava or "Chinese Corydalis"), suitable polar solvents are methanol or water, and the water immiscible solvents are halogenated hydrocarbons.  The active extract is said to contain the alkaloids dehydrocorydaline, tetrahydropalmatine, and protopine. Compositions of the active substance may take the form of tablets, powders, or capsules, with a pharmaceutically acceptable carrier; an Example is given for preparation of tablets, using conventional excipients.

The ports 16 for the rich mixture and the adjoining parts of the passages 20 are arranged such that the rich mixture issues both generally tangentially of the adjacent piston flank 11 and towards the leading end of a recess 12 in the said flank, as indicated by arrows 21, 22 in Figs. 2 and 4. Alternatively, the rich-mixture ports and passages are formed in the peripheral wall 1, Figs. 5 and 6 (not shown). The engine may be modified such that the rich mixture passes through passages in the eccentric 5 and piston 6 prior to its egression from the ports 16 so as to both vapourize the fuel and cool the eccentric and piston, Fig. 7 (not shown).

Abstract: 1,023,287. Coiling. CROSS MANUFACTURING CO. (1938) Ltd. Aug. 12, 1964 [Nov. 20, 1963], No. 45796/63. Heading B3E. Apparatus for forming polygonal windings from metal wire or strip stock comprises a rotatable mandrel composed of a number of rods disposed parallel with one another in equi-spaced disposition around the common axis of the mandrel, and carried by end plates in a manner whereby the rod-ends can be adjusted radially in the plates, thus forming a mandrel the effective diameter of which can be varied, said mandrel being mounted on suitable framework with means to rotate the mandrel on the framework. The wound wire may be severed into convolutions to form cockle rings for use with piston rings. End plates 1, 2 on a rotated shaft 4 carry between them rods 3 adjustable radially of the plates. A traversing screw 11 supports a feed device for the wire as it progresses along the mandrel. The stock is heated to red heat immediately prior to it being wound on the mandrel.

Abstract: 984,838. Photographic transfer processes. AGFA A.G. Dec. 5,1962 [Dec. 8, 1961],No. 45976/62. Heading G2C. In a process wherein an exposed gelatine silver halide material containing a tanning developer is developed by heat, and the unhardened parts are transferred during or after development to a receiving sheet to give a positive image (see Specification 821, 506), the receiving sheet contains a thiosemicarbazide or an alkyl, aryl, aralkyl, acyl or substituted aryl derivative thereof. The thiosemicarbazide may be substituted in the 1- position by a phenyl,formyl, methyl or acetyl group or in the H-position by a methyl, ethyl, hexyl, dodecyl, cyclohexyl, 4-methylcyclohexyl, phenyl,p-tolyl,p-methoxyphenyl,benzyl or #- phenylethyl group. Moisture-providing substances may be included in the light-sensitive or transfer layer. These may be substances which split off water on heating such as sodium acetate, or compounds which increase the moisture content of the layer, such as sorbitol, glycerol or polyalkylene glycols. In the examples, the silver halide emulsion contains pyrocatechol, cyclohexanone bisulphite, sodium acetate and benztriazole.

In a coulometric titration cell, the current through the titration electrodes is supplied by an amplifier so as to be proportional to the difference between the output potential of a measuring electrode and that of a reference electrode, the current falling to zero when the desired end-point pH is reached. The cell comprises two vessels 1 and 2 inter-connected by a pipe which contains two porous sintered glass discs 4 and a glass filter disc 5 coated with a layer of silica gel. Two platinum wire mesh electrodes 7, 8 are supplied from the output of a power amplifier 42 through a device 44 which measures the number of Coulombs consumed during titration. The cell also includes a measuring electrode system 11 comprising a glass measuring electrode and a calomel reference electrode. The reference electrode is connected to a differential amplifier 16 so that an adjustable voltage from a cell 24 can be added to (or subtracted from) the output of the reference electrode to set the desired end-point of the titration. The output of the measuring electrode is also connected to an operational amplifier 13 for impedance matching. The outputs of the two amplifiers 16,13 form the inputs to a differential amplifier 12, the gain of which is stabilized by feedback over resistor 37, and which is adjusted so as to give zero output when the two input signals are equal, i.e. when the end-point of the titration has been reached. This output signal controls via amplifier 41, the power amplifier 42 which supplies the electrodes 7, 8. The gain of the amplifiers 41, 42 is reduced when the input signal is large by feedback over the semiconductor diodes; 55, 56. A phase-shift network 50, 51 is included to prevent hunting.

Abstract: 1,223,207. Fluid-pressure servomotor systems. GENERAL SIGNAL CORP. Sept.19, 1969 [Oct. 23, 1968], No. 46288/69. Heading G3P. The hydraulic system described in Specification 1,178, 207 is modified by providing a reference orifice 45 between pump P and valve 17, and a variable orifice 46 which is in the same bridge leg 31 as command orifice 36 and is varied, by hydraulic motors 48, 49 in response to changes in the pressure drop across orifice 45, in such a way that if this pressure drop exceeds a predetermined value, orifice 46 unbalances the pressures at junctions 26, 27 in a sense which causes control valve 22 to reduce the delivery rate. The circuit includes a further valve 18 and associated reference orifice 51 with a check valve 53 permitting flow from orifice 45 to 51. As shown orifice 46 is closed when valve 17 is in its neutral position and its flow area decreases as the pressure drop across orifice 45 rises, but according to various modifications (Figs.2-5, not shown) this arrangement is reversed and the command orifices 35-37 are connected in series, or series parallel, with orifice 46. Rams 13-15 can be used to operate the lift tilt and grab arms of a fork lift truck.

Abstract: 921,892. Sewing-machines. E. A. FONTANA. Dec. 28, 1961, No. 46388/61. Class 112. [Also in Group XXXI] A sewing-machine foldable below a table top is provided with a treadle-operated belt drive adapted to be kept under tension during the folding operation as well as in the folded position of the machine. The base 3 of sewing-machine 4 is hinged at 5 to a table top 1, and the sewing- machine may thereby be lowered within a compartment 7 under the table top. A bracket 14, depending from base 3, carries at its lower corners pulleys 20 and 21. An arm 22, pivoted at 18 to bracket 14, carries a pulley 24 which is biased by a spring 25 into engagement with belt 13. A link 29 connects arm 22 to an arm 28 which is pivoted at 17 to bracket 14 and carries adjustably at its free end a pulley 32 fitted with a rubber tyre 33. When the machine is lowered, belt 13 is strained over the pulleys 20, 21 and 24, and tyre 33 engages the rim of driving pulley 11 to serve as a brake therefor. It is stated that the brake pulley 32 may alternatively either be carried by arm 22 or be omitted, when pulley 20 is replaced by a rigid member having a circumferential groove the cross section of which differs from that of belt 13 and thus serves as a brake for the latter.
