Title: Improvements in or relating to imidazole derivatives
Inventor: JACOB ROBERT MICHEL
IPC: C07D233/92
Filed: 1960-07-01
Abstract: The invention comprises a monoester of an imidazole of the general formula <FORM:0901060/IV (b)/1> wherein R is a C1-5 alkyl group, A is a divalent straight or branched chain C2-4-aliphatic hydrocarbon group in the ester group is a pivaloyl, benzoyl, chloro, nitro or methoxy benzoyl group or a bis-ester of a said imidazole in which the ester group is derived from succinic or phthalic acid, their acid addition salts and pharmaceutical compositions containing them. The compounds of the invention may be prepared by esterification of the corresponding alcohols.  Pharmaceutical compositions for enteral, parenteral and topical administration comprising the imidazole esters in association with a pharmaceutical carrier are useful in the treatment of infections due to pathogenic protozoa.  Examples are given of tablets containing the succinic ester and benzoic ester of 1-(2-hydroxyethyl)-2-methyl-5-nitroimidazole.

A plurality of inward flow filtering bags 3 are sequentially cleaned by engagement of their outlet ends by a nozzle 41 which is mounted on a carriage 1 carrying a reverse flow blower 4, the carriage travelling on rails 24 in the filtered air outlet chamber. The carriage may be remotely driven or may be moved by the motor which drives blower 4, through suitable gears and clutches 12..18. Bags 3 may be arranged in a circle, or in parallel rows as shown; in the latter case the carriage travels rectilinearly and limit stops actuate a pair of clutches 14 to reverse the direction of travel. The carriage may have one nozzle 41 which swings from one side to the other on reversing the travel, to clean two rows of bags in turn, or a plurality of nozzles, possibly with separate sequentially opened flaps (Fig. 3, not shown) may be connected to one blower. The bags are supported by internal springs 31, and arranged to tighten as the nozzle suddenly engages them. To this end, the carriage may be driven quickly over an opening and stop thereon, using electromagnetic clutches 14, or protuberences 8 on dividing plate 27 may engage a flexible nozzle so that it springs suddenly over the opening, or the opening may be shaped (7), (Fig. 2, not shown) to partially close the top of a bag and reduce 'blowing time'.

Suitable acid halides include phosphorus oxychloride, phosphorus oxybromide, phosphorus tribromide or trichloride or thienyl chloride which may be used singly or in mixtures. Advantageously an excess of acid chloride is used so that it also serves as a solvent. The phosphorus pentoxide is used in an amount of 0À2- 2 mols. per mole of naphtholactam derivatives, preferably they are present in equimolar amounts. The compounds dye polyacrylonitrile material in blue and violet shades.

Abstract: 769,495. Bore-hole clinometers. SOC. DE PROSPECTION ELECTRIQUE PROCEDES SCHLUMBERGER. Aug. 10, 1954 [Aug. 29, 1953], No. 23263/54. Class 97(2) A bore-hole clinometer comprises a compass which is subjected to vibrations to prevent the needle sticking, a member pivotable about the longitudinal axis of the clinometer and carrying an off-centre weight, and a pendulum pivoted on said member, the compass, pivotable member and pendulum each being arranged to operate circuit control member which members are connected in a circuit so as to record or indicate the angles of the said members. As shown, the casing 10 contains a vibrator 14 which, via the rod 16, imparts weak vibrations to the compass suspension 18. The compass mount 19 is suspended to remain horizontal at all angles of the casing 10 and the rotation of the compass needle is communicated to the arm of a potentiometer 22 the resistance of which is proportional to the position of the compass needle. A cylinder 23 is suspended on pivots 26, 27 and one side is weighted by an elongated bar (not shown), which when the apparatus is not vertical, rotates the cylinder 23 so that the off-centre weight assumes the lowest position. This rotation is communicated to the arm of a potentiometer 29 whose resistance is thus a measure of the direction of the plane containing the bore-hole axis. A pendulum 31 is pivoted at 30 to swing in a plane through the axis 26-27 and the longitudinal axis of the off-centre weight. The movements of the pendulum are communicated by rack and pinion gears 32 to a potentiometer 34, the resistance of which is thus a measure of the deviation of the borehole from the vertical. The potentiometers 23, 29 and 34 are connected into a circuit at the surface by leads 11, the circuit being arranged to operate recording or indicating instruments. Specification 644,466 is referred to.

Abstract: 1,070,058. Sampling liquids. C. W. MAXWELL. June 1, 1965 [June 8, 1964], No. 23270/65. Heading B8N. An apparatus for sampling liquid, such as for use with a milking machine, comprises a delivery conduit 1 having an outlet 4 leading into a collecting chamber 19 via an annular jet-like opening 6, a proportion of the flow passing through a passageway 10, 14 into a sample chamber 15, outlet ports 26, 27 leading from the collecting and sample chambers respectively. The annular jet - like opening is formed by means of a lip 6 surrounding a 'dished surface 5 formed in a member (3, Fig. 1) which is mounted on the conduit 1, and a plate 12 spaced from the lip and forming a cover for the collecting chamber 19; the member (3) is formed with a skirt portion 7 over which the bulk of the milk flows into the latter chamber. A small proportion of the milk flow passes through the skirt portion via the passageway 14 and then into the sample chamber 15. In operation, the lower end of the delivery conduit is connected to a milking plant so that the milk is sucked up conduit 1 and flows through the annular jet, into the collecting chamber, a three-way valve 31 being positioned to connect the collecting chamber with the suction side of the milking plant. A fraction of the milk flow passes into the sample chamber through the port 14, a gauge glass 30 being connected to the chamber and calibrated to indicate the total amount of milk given by a particular cow. After the milking operation the sample of milk may be drained out of the chamber 15 for testing by opening a valve (34, Fig. 8) or, by rotating the three-way valve to connect the sample chamber with the suction, the sample milk may be drawn off into the bulk supply.

Buttonhole sewing-machines; thread cutters and thread-end holders. -Provision is made in a buttonhole sewing-machine to separate the work and threads at the completion of each hole, to permit easy and harmless operation of the thread-cutter. The invention is described as applied to a machine with stitch - forming mechanism, as described in Specification 179,278. buttonhole cutting and work-clamping mechanism as described in Specification 183,873, and thread-cutting mechanism as described in Specifications 223,124 and 223,801. Access to to the threads by the cutting mechanism 41, 45 is obtained by periodically lifting the frontend of the work-support 24 by a cam 72, Fig. 8, when the work-clamps 25 are holding the finished buttonhole just after it has been cut by the cutters 16, 17. The thread-cutter consists of a pair of scissors 41, 45. The blade 41 is carried by a lever 42 pivoted at 43 to the frame. The blade 45 is pivoted to the other blade at 44 and its tail has a later projection 46 entering a cam-slot 47 in the plate 48 for closing them. The lever 42 is operated by the link 49, lever 50, and gearing connected to the main shaft as described in Specification 223,801. The means for lifting the work-clamp is carried by the thread-cutter lever 42. Two pins 71 secured thereto carry a cam 72 with a circular portion 73 and a cam portion 74. These portions engage a roller 61 carried by a plate 60 which has a pair of sleeves 69 in which are pins 58. The pins have notches 62 engaged by a plate 63 normally urged to locking position by a spring 67, Fig. 3. When the work-clamp is shifted to buttonhole cutting position, Fig. 8, the roller 61 lies directly over the plate 72, so that as the lever 42 is operated to advance the thread-cutter 41, 45, the pins 58 are lifted, so tilting the work-clamp and giving free access to the under thread, needle-loop threads, and stay-cord c, to permit cutting without danger of damaging the under-surface of the material, whatever its texture. The point 41' of the upper blade is preferably offset towards the work-plate. The cutter mechanism carries a thread-nipper of the kind described in Specification 223,124.
