Title: Improvements in and relating to a process for producing benzenesulfonylguanidines
IPC: C07C311/64
Filed: 1955-02-10
Abstract: Benzenesulphonylguanidines of the general formula R.C6H4SO2NHC(: NH)NH2, in which R is a hydrogen atom, a para-methyl or a para-amino group are prepared by reacting a sulphonamide R.C6H4SO2NH2 with calcium cyanamide in the presence of water under influence of heat. The reaction may be carried out in the presence of water as such, e.g. in aqueous suspension, with or without the addition of a compound yielding water under the conditions of the reaction, preferably by boiling; or in a melting operation in the presence of a compound decomposing under the reaction conditions to yield water, preferably at from 150 DEG  to 200 DEG  C.  Compounds yielding water include compounds containing water of crystallization, inorganic acids containing water, ammonium salts of organic aliphatic acids, organic amides and aliphatic polyalcohols.  The melting procedure is facilitated by the addition of substances which will maintain the reaction mixture in a fluid, stirrable state, e.g. metal salts of acids, such as calcium chloride or sodium acetate, phenol ethers such as anisole, and inorganic acids such as phosphoric acid or boric acid.  In either procedure metal salts such as sodium chloride, calcium chloride, aluminium chloride, zinc chloride and sodium bromide may be added to stabilize the product and any unreacted sulphonamide.  In the melting process the reaction mixture may subsequently be dissolved in hot water containing an alkali metal carbonate and filtered, and the filtrate cooled, when the required product crystallizes.  In examples of the melting procedure the following substances are added to a reaction mixture of sulphanilamide and calcium cyanamide: (1) no additions (comparative example); (2) commercial calcium chloride and crystalline sodium acetate; (3) CaCl2.2H2O and sodium chloride; (4) CaCl2, NaBr and crystalline CH3COONa; (5) acetamide; (6) CaCl2 and acetamide; (7) crystalline oxalic acid (or boric or phosphoric acid) and CaCl2; and (8) anisole and CaCl2.2H2O. In further examples: (9) sulphanilamide, calcium cyanamide and water are heated, sodium carbonate is added, the mixture is filtered and caustic soda is added to the filtrate when sulphaguanidine separates; CaCl2 with or without acetamide may also be added; (10)-(12) MgCl2 and CaCl2, NaBr with CaCl2 and acetamide, and ammonium acetate are added in the process of (9); (13) benzene sulphonamide, calcium cyanamide, CaCl2 and acetamide in the melt process give benzene sulphonyl guanidine; (14) p - toluenesulphonamide, calcium cyanamide, CaCl2 and acetamide give p-toluene-sulphonylguanidine

Abstract: 1419660 Electrical medical apparatus ESB INC 26 Jan 1973 [28 Jan 1972 19 Sept 1972 22 Dec 1972] 4154/73 Heading A5R An electrical medical device for modifying the naturally occuring electric potential of a zone of a living body has an electric signal generator producing a signal of cyclic waveform, each cycle of which has a rising and a falling portion and of which the rise and fall times differ by at least one order of magnitude and in which one of said portions has a frequency content within the range of from 10 Hz to 1 MHz, and coupling means in the form of electrodes or a coil connected to the generator and operative for reactively coupling said signal to said body zone. The generator may comprise a blocking oscillator including transistors 25, 26 and a feedback transformer 34 developing an asymmetrical sawtooth voltage across capacitor 28, this voltage being coupled via a d.c. blocking capacitor 43 to electrodes 50, 52, or via an operational amplifier (47), Fig. 2 (not shown), to one or more coils (50a), (52a). The rise time may be greater or less than the fall time which is chosen so that the falling waveform portions have little effect on the zone being treated. The frequency components of the effective rising portions are chosen in dependence on the zone treated: e.g. 10 Hz to 10 KHz for deep tissue, 10 KHz to 50 KHz for intermediate depths, 50 KHz to 200 KHz for subcutaneous tissue, 200 KHz to 1 MHz for cutaceous tissue. Electrode 52 may be about five times smaller than electrode 50, and the electrodes may be made of silver or a semiconductor, a dielectric material being placed between the electrodes and epithelical surfaces of the body. If coupling coil(s) are used they may be embedded in the treated zone. The generator with or without a power supply battery may be implantable and encapsulated in a body-compatible compound, and one of the electrodes 50, 52 may then take the form of a plate secured to the encapsulating casting, or each of the coils (50a), (52a) may be a wire wound bobbin secured to the casting. The electrodes or coils may be adapted to the form of a splint, cast or bandage around the treatment zone, or to a part of a splint, cast or bandage. The generator may be embedded in such a cast.

Title: Electric calculating device
IPC: G06G7/163
Filed: 1943-03-26
Abstract: 574,841. Electrical calculating apparatus. SULZBERGER, A. March 26, 1943, No. 4972. [Class 106 (i)] An electrical calculating device for determining the value of a function having the form comprises an electric network consisting 1/1 + A of constant electric circuit elements and having four pairs of terminals A1, A2, A3, A4 of which two pairs A1, A2 are bridged by a system consisting of one or several interconnected networks, whereby the total transformation ratio of this system existing at the two bridged pairs of terminals is made variable, and whereby the transformation ratio existing between the pairs of terminals A3, A4 represents the function 1/1 + A to be determined. The invention is further applied to the evaluation of a function which can be transformed into the form B / 1 + A , where A and B are each a function of two variables x, y. In Fig. 1, A and B are resolved individually into the product of two functions of x and y separately and networks B, C representing A and networks D, E representing B are arranged to represent these functions when shafts F, G are rotated according to x, y respectively. The output terminals C2 are connected to one pair of input terminals K1 of a six-terminal network K, while the output terminals of another four-terminal network L, connected to the same source of current H, are connected to the other input terminals K2. When the potentials at K1, K2 are equal, the indicator Q reads zero and the angular position of the shaft R represents the solution. Certain conditions must be fulfilled; these include that P13, P24 are zero, P14.P23 is equal to P12.P34 and P12 or PD.PE is negative, where P13 represents the transformation ratio between pairs of terminals A1 and A3; also the transformation ratio between pairs of terminals K1 and K2 must be zero. The arrangement shown in Fig. 5 is used for the determination of a function of the form where the four-terminal networks S, T, U are used for representing the functions in x, y, z, respectively. The terminals S2 and V5 are bridged by networks similar to L and K in Fig. 1 to indicate the solution of the problem. The constant and variable circuit elements may be resistances, coils or condensers ; the power H may be A.C. or D.C. Instead of using potential transformation ratios, current transformation ratios may be used. Specification 520,228 is referred to.

A plied yarn product composed of at least two yarns having any desired but a same twist is formed by doubling yarns having the same twist but differing from the desired twist with the aid of a one-spindle doubling device, i.e. a device in which yarn drawn from one package is balloned around the yarn from another package with the aid of a rotating guide, and subsequently, twisting the cord thus formed on a twisting device. In the arrangement shown yarn 3 from spool 1 is balloned around stationary spool 2 and is doubled with the yarn 4 from the spool 2 at point 5. The plied yarn product 6 is then passed between rollers 21 and 22 to a ring twisting device. In one example a cord having a twist of 12S composed of yarns having a twist of O is formed from yarns of twist 2Z by first doubling the yarns on a one-spindle doubling device with a twist 10S and subsequently twisting the cord on a twisting device with a twist of 2S.
