Title: New diuretic agents
Filed: 1956-12-31
Abstract: The invention comprises xanthine derivatives containing mercury prepared by introducing an allyl group into a xanthine derivative of formula: <FORM:0813430/IV (b)/1> wherein one R is methyl and the other hydrogen to give a derivative in which one R is methyl and the other allyl, exchanging the 8-halogen for a water-solubilizing group, reacting the so-formed product with a water-soluble mercury compound and, if necessary, neutralizing.  In order to exchange the 8-halogen, a compound is used containing a group which reacts with halogen and a water-solubilizing group; the group which reacts with halogen may be the water-solubilizing group, e.g. an amine.  Compounds possessing a group exchangeable with halogen and separate from the water-solubilizing group include carboxylic acids or sulphonic acids of amino-, hydroxy- or mercapto-compounds or amino-hydroxy compounds. The new mercury-containing compounds may be used as diuretics.  In an example:  (a) 1 - Allyl - 3,7 - dimethyl - 8 - chloro - xanthine [I] is prepared by reacting allyl bromide with 3,7-dimethyl-8-chloroxanthine in the presence of caustic soda;  (b) 1 - Allyl - 3,7 - dimethylxanthine - mercapto acetic acid (8) [II] is prepared by reacting [I] with thioglycollic acid in ethyl alcohol; (c) 1 - (31 - acetoxymercuri - 21 - methoxy) - n - propyl - 3,7 - dimethylxanthine mercapto acetic acid (8) [III] is prepared by reacting [II] with mercuric acetate in methanol. The product [III] may be used as its sodium salt or as its salt with 1-dimethylamino-ethyl-3,7-dimethylxanthine.  Other compounds prepared include 1 - (31 - acetoxy - mercuri - 21 - methoxy) - n - propyl - 3,7 - dimethyl - 8 - dimethylamino - xanthine monoacetate; 1-(31-acetoxymercuri - 21 - methoxy) - n - propyl - 3,7 - dimethyl - 8 - b  - dimethylaminoethoxy - xanthine monoacetate; 1 - (31 - acetoxymercuri - 21 - methoxy) - n - propyl - 3,7 - dimethyl - 8 - b -aminoethylamino - xanthinediacetate; and 1,3-dimethyl - 7 - (31 - acetoxy - mercuri - 21 - methoxy) - n - propyl - 8 - b  - diethylaminoethoxyxanthine monoacetate.  1 - Allyl - 3 : 7 - dimethyl - 8 - dimethylamino- and 8-b -aminoethylamino-xanthine are prepared by reacting [I] above with dimethylamine and ethylenediamine respectively, and liberating the bases from the resulting hydrochlorides.  1 - Allyl - 3 : 7 - dimethyl - 8 - b  - dimethylaminoethoxyxanthine is prepared by reacting [I] with a solution of sodium in b -dimethylaminoethanol.  1 : 3 - Dimethyl - 7 - allyl - 8 - b  - diethylaminoethoxyxanthine is prepared by reaction of a solution of sodium in b -diethylamino ethanol with 1 : 3 - dimethyl - 7 - allyl - 8 - bromoxanthine, itself obtained by the action of allyl bromide on 8-bromotheophyllin.

Abstract: 1,269,347. Travelling wave shedding looms. A. LINKA. 13 Aug., 1969 [16 Aug., 1968], No. 40389/69. Heading D1E. A shuttle 1 of a travelling wave shedding loom is driven magnetically by magnets 7 in a moving member 9 cooperating with a plurality of similar magnets 5 in the shuttle 1. The side of the shuttle track is formed by a comb 3 into the spaces of which the warps 4 are pressed as the shuttle passes, the side of the shuttle adjacent the comb being faced with a layer of low friction material such as tetrafluorethylene. During motion the poles of the two sets of magnets are displaced so that a pole of a magnet 7 lies opposite the space between a pair of poles of the magnets 5, whereby the attraction and separation between unlike and like poles produce, on each pole of the magnets 5, forces the components of which along the length of the track are all in the same direction to produce a strong driving force whilst at right angles to the track they oppose one another to reduce the force with which the shuttle bears against the comb 3.

Abstract: 1334319 Integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1972 [15 Nov 1971] 41083/72 Heading H1K In the step of diffusing to form the emitter of a transistor forming part of a monolithic integrated circuit the doping impurity concentrations and conditions are so selected that the conductivity type of the previously formed emitter of a complementary transistor, which is exposed during the diffusion, remains unaltered. A typical IC, Fig. 8, is produced by first diffusing phosphorus into a surface region of a P-silicon substrate and then remasking and diffusing boron to form P+regions. The masking is removed and during epitaxial growth of an N type layer the boron and phosphorus outdiffuse to form collector regions of complementary transistors 13, 15 and parts of isolation regions 30. Phosphorus is diffused into the epitaxial layer through oxide masking to form N+ base region 33 and collector feed-through regions 25, and then boron is diffused to complete the isolation regions 30 and form P + base region 21 and collector feed-through region 37. After removal of the masking, layers of silica and silicon nitride are deposited and arsenic diffused through apertures therein for 110 minutes at 1000 C. to give a surface concentration of 5 x 10<SP>20</SP> atoms (cc.) in emitter region 23 and in collector and base contact regions 47, 39. Additional openings are formed in the silicon and nitride and boron diffused in at 1000 C. for 23 minutes to form emitter region 35 and base and collector regions 27, 29, 36 with a surface concentration of 1À5 Î 10<SP>20</SP> atoms/cc. Then, using the already formed openings in the masking the contact metallurgy is provided. Resistors, capacitors, and Schottky diodes may be provided in other isolated regions by the described diffusion steps. Doping concentrations, diffusion times and temperatures and masking details are given.

Abstract: 1,031,580. Ingition systems. GLOB-UNION Inc. Oct. 14, 1964, No. 41840/64. Heading F1B. An ignition system comprises an oscillator for generating voltage pulses, means for amplifying the pulses and a control circuit connected to the amplifier means and operative to permit the application to the amplifier means of only a limited number of oscillator pulses which have an amplitude sufficient to cause ignition after amplification by the amplifier as shown current is supplied to the circuit from a battery 36 by closing switch 38 producing a near square-wave alternating current in the transformer. A circuit breaker switch 40, which may be either cam operated or of a commutator type, when closed will shunt winding 26 so that no voltage will be induced in the transformer. The voltage rise across resistor 50 and capacitor 52 will reduce the gain of the amplifier transistor and tend to reduce the current through the resistor 50. After several cycles a condition of equilibrium will be reached when the voltage across the resistor capacitor circuit reaches a steady valve. This additional bias causes the amplifier to run at reduced gain. In order to minimize spark plug erosion by reducing the number of sparkes in each firing cycle the wave form applied to the step up transformer is limited to one or only a few cycles at full amplitude by suppressing all subsequent cycles. This is accomplished by rectifier 56 and resistor 58 forming a bias supply deriving its power from winding 46. A modification employing a push-pull blocking oscillator and a push-pull amplifier is described. Common base or common collector oscillator would serve equally well. The system may employ surface gap plugs.
