Title: Process for the production of injectable sulphonamide suspensions
Inventor: MOEHRING MANFRED
IPC: A61K9/00
Filed: 1961-05-11
Abstract: Injectable and instillable sulphonamide suspensions are prepared by grinding one or more sulphonamides, which are insoluble or difficultly soluble in water, to a particle size of less than 100 microns and then mixing with an aqueous solution of one or more salts of alkali metals, alkaline earth metals or organic bases with sulphonamides containing free sulphonic acid groups.  These sulphonamides may be (a) p-amino-benzene sulphonylamino alkyl sulphonic acids of formula <FORM:0928306/VI/1> in which R is an unbranched alkylene radical containing 1 to 12 carbon atoms; (b) p-amino-sulphonamides carrying N-alkyl sulphonic acid residue of formula <FORM:0928306/VI/2> in which R has the meaning above; (c) p-amino-sulphonamides which have attached thereto via an azo bridge member, an aromatic residue which is sulphonated or which bears an N-alkyl sulphonic acid residue of formula <FORM:0928306/VI/3> or <FORM:0928306/VI/4> wherein R has the meaning above, and X (in all cases) is an alkali metal, alkaline earth metal or organic amine. The amount of finely-divided sulphonamide in the suspension is 5 to 50 g./100 ml. and the amount of water-soluble sulphonamide is 5 to 70 g./100 ml.  The preparations are useful for the prevention or combatting of infections in humans and animals.

External fins 2a, 2b are formed on a tubular workpiece 1 by enclosing it between segmental dies 4 having internal grooves, and drawing an expanding tool 24 through the workpiece bore to cause flow of the workpiece material into the grooves of the dies. The fins 2a, 2b are inclined in opposite directions to the workpiece axis. Die segments 4 are movable into radially open or closed positions by jacks 10 and are held in their closed positions by sleeves 12, 14 movable axially on a frame 6 by jacks (not shown). Spring-loaded stops 20 locate the workpiece whilst the tool 24, housing balls 26 or tapered rollers to reduce friction, is pulled through and simultaneously rotated by drive mechanism, Fig. 2b (not shown). The grooves in the die are deeper than the height of the fins so as to limit the pressure of air trapped therein; alternatively air vents may be provided in the grooves. Heating electrodes 40 (Fig. 3, not shown), may be provided in the dies 4. The workpiece may be of hexagonal external cross-section made of a magnesium-zirconium alloy and used for housing a nuclear fuel element. Subsequently the fins 2a, 2b are machined, e.g. by milling, whilst enclosed in a jacket of ice which both supports the fins during machining and cools the cutting tool.

[Also in Division F2] A balancing unit for rotary bodies comprises a correcting mass 19 and means for adjusting the stress axially of the rotary body and angularly about its axis to balance the body during its rotation. As applied to a drive spindle 5 mounting a grinding wheel 7 the correcting means 19 is mounted on a worm-wheel 17 which rotates about a spindle 18 lying in a plane at right angles to the axis XX. An electric motor 14, supplied via brush 27 and lead 25, drives the worm-wheel through gearing 16 and worm 15. The latter assembly is mounted in a housing 10 which may be rotated about axis XX by an electric motor 20 driving, through gearing 21, a pinion 22 which meshes with internal gearing 24.  Operation.-With the spindle 1 rotating motor 14 is energized to rotate mass 19 to move it axially of the spindle into any position in which it is not on axis XX (i.e. the position shown in broken lines). Motor 20 is then energized to rotate the mass about axis XX until a first minimum vibration position is attained, the vibrations being transmitted via a pick-up 29 and an amplifier 30 to vibration meter 31. Motor 14 is again energized until a second minimum vibration level is detected. The position of the mass 19 may be detected electrically by devices 32, 36 and displayed at 35.  The balancing may be effected automatically by an electrical control system (not described). The brushes 27, 28, 34, 38 may consist of a single or multi-brush assembly.

Abstract: 575,089. Driving gear. AKTIEBOLAGET BOLINDER-MUNKTELL. Sept. '19, 1944, No. 17859. Convention date, Dec. 23; 1943. [Classes 7 (ii) and 7 (v)] [Also in Group XXVI] In an engine, particularly a lifeboat Diesel engine, in which the fly-wheel is enclosed and acts as a bilge pump, means are provided for controlling the output of the pump and thus the ratio of power delivered from the crank-shaft to the propeller shaft and the pump. The flywheel 14 rotates in a sheet metal casing 18 and the inlet is controlled by a plate valve 38 attached to a screwed spindle 40 which can be rotated by a handle 42 arranged above the casing. Water is deflected from the outer surface of the fly-wheel by a scraper plate having small clearance therewith and arranged adjacent the outlet. A reversing gear 10 has a neutral position so that all the engine power may be delivered to the pump. The engine is started by an explosive cartridge which is fired in the combustion chamber, the fly-wheel having a mark, visible through a window 28, indicating the correct starting position. It may be turned to this position by rotating a handle 25 connected to the crank-shaft by a chain 26. A governor prevents racing when the engine is started before the boat reaches the water.

Abstract: 455,315. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. June 21, 1935, No. 17879. Convention date, Feb. 15. [Class 130] In a cigarette-collecting mechanism in which cigarettes are advanced lengthwise in spaced relation and displaced laterally for transverse delivery, suction means are provided to retard or stop the lengthwise movement of the cigarettes. In the construction shown in Figs. 1 and 2. cigarettes delivered by a continuous - rod machine over a table 1 are accelerated and separated by an enlarged segment of sponge rubber on a rotating roller 10, and are moved sideways on to a perforated belt 16 by a reciprocating pusher 15. The pusher is provided with suction passages 38, terminating in its front face, which normally register with suction chambers 33, 33a to retard the longitudinal motion of the cigarettes. Needle valves 39 regulate the degree of suction in the passages 38. At the end of the forward stroke of the pusher the suction is cut off as the ends 36, 37 of the passages 38 move out of register with the chambers 33, 33a and the cigarettes are subjected to a further suction effect, to retard any remaining longitudinal movement the cigarettes may possess, as the rows of perforations 41 in the belt 16 move over stationary suction chambers 42. Cigarettes having abnormally high speeds are stopped by engagement with an abutment 40 adjustably mounted on the pusher 15, which is provided with a rib 25 guided in a slot in a table 26 and is advanced by a roller 24 carried by a rotating crank 17 and returned by springs 27. In the modified construction shown in Fig. 4, the cigarettes, after being separated by a rotating roller 50, are moved sideways over a stationary suction chamber 56 by a pusher 55 which is given an orbital movement by cranks 57. The chamber 56 has two rows 65, 66 of perforations, each cigarette in turn being positioned over the row 65, being displaced on to the row 66 by the next cigarette, and being displaced on to a delivery belt by a following cigarette. Specifications 412,502 and 420,821 are referred to.

About 30% of the paper may constitute this product. In examples a P.V.C.-P.V. acetate copolymer is used, dissolved in acetone and precipitated with aqueous acetone below 25‹ C. The paper may exhibit a concentration gradient of the polymer across its thickness, one side being substantially polymer-free.
