IPC: A61K31/43
Filed: 1950-02-07
Abstract: Procaine-penicillin G is prepared in a form suitable for the extemporaneous preparation of an aqueous suspension, by coating particles of the procaine-penicillin G at least in part with at least one monoaminomonophospholipid, particularly a - and b -lecithin, a - and b -cephalin, partially hydroxtlated lecithin or cephalin, and mixtures thereof in the proportions of 1 to 10 per cent, and preferably 7.4 per cent, by weight.  The particle size of the coated procaine-penicillin G is sufficiently small to pass a 60-mesh B.S.S. sieve.  According to the example, a partially hydroxylated soyabean lecithin-cephalin monoaminomonophospholipid mixture is dissolved in chloroform, the solution sterilized by filtration through a Leitz filter pad, the sterile solution mixed under sterile conditions with sterile powdered procaine-penicillin G and the coated particles produced by removing the solvent under reduced pressure at a temperature below 50 DEG  C., are milled to pass a 60-mesh sieve. The powder may be stored in sterile bottles and, when required, may be suspended in water or normal saline solution by shaking.  Other organic solvents boiling below 100 DEG  C., such as petroleum ether and carbon tetrachloride, may be used in place of the chloroform.

A hatch 6 is then installed, walls 12 are inserted to form a ventilation channel 13 and traffic lanes 14, and temporary bulkheads are added to close the ends of said channel and lanes and thereby render the section buoyant. A protective layer 10 of concrete may be applied before the structure is floated to the. site. Finally, a concrete lining 11 is formed in stages, as shown, such that the joists or trusses are fully embedded therein so as to produce a "composite action structure", and ballast 15 is added to sink the completed section. Rods (21), Fig. 4 (not shown), to provide extra reinforcement may be included in the lining. The upper portion of the skin may be omitted to facilitate formation of the lining, Fig. 2a (not shown), and three walls 12 inserted so as to form two lateral channels 13 with the lanes 14 located therebetween. When the upper part of the lining has been formed a skin (17), of glass-fibre-cored bituminous-felt, Fig. 2d (not shown), is placed thereover to exclude water and the layer 10 is then completed so as to cover this skin. An open-topped structure to form a ventilation building for the tunnel may be constructed in a similar manner, Fig. 3 (not shown).

Abstract: 211,148. Knapen, J. Feb. 8, 1924. Inclined-trough washing-apparatus; upwardcurrent-classifiers.-In a washer for small coal, an obstacle 3, Fig. 2, is placed in the channel 1 to impede the current and cause deposition of heavy impurities which pass on to and through a strainer 4, or through an adjustable opening 6, into a vessel 2, kept constantly filled with water, and through a tube 12, provided with a valve 13 preferably automatically operated by the weight of the materials, to a tank 18 provided with a strainer 19 and an elevator 17. A division wall 7 may be placed in the vessel 2 and part of the current therein deviated past a waterjet device 10, impurities passing through a screen 9. If the discharge of water through the tube 12 is undulv great, a float 15, carried by a piston 16 in a laterally-placed tube 14, enters the tube 12, consequent disturbance in the veesel 2 giving an indication to the operator. In a modification, the strainer 4 is replaced by two or more stepped strainers of variable length; while, in a further form, a current of water fed to the lower side of the vessel 2 from an overhead reservoir is led downwards by a division wall extending below the wall 7, causing eddy currents below these walls to assist the washing. In the form shown in Fig. 4, instead of an obstacle 3, the inclination of the channel is increased at the strainer 4; a current of water is fed to the vessel 2 from a reservoir 2.

Class 143 An apparatus for sorting pieces of dough by weight comprises a belt conveyer 12 supported on a scale 31, means for feeding pieces singly to the conveyer, means for unlocking the scale only when the conveyer is loaded and means to deflect automatically over or under weight pieces from the stream. As each piece is fed on to the conveyer it pivots a lever 17 which, through a shaft 15, cam 16, lever 19 and rod 22, rocks a toggle lever 20 about a pivot pin 24 and disengages a pair of arms 21, 21a, secured 'to the movable part of the scale, from a bar (not shown), carried by a finned part of the apparatus, so unlocking the scale and, if the piece is under or over weight, allowing the frame 10, together with the loaded conveyer supported thereby, to move to a level determined by the weight of the piece. This movement is transmitted by pin 24 through a linkage (not shown), to a contact arm 26 which is pivoted to a finned part of the scale and co-operates with contacts 30, 30a. Should this movement be sufficient to cause arm 26 to make contact with either of contacts 30, 30a, a circuit is closed through a solenoid 36 which operates a diverting flap (not shown), in a main shoot 32. Subsequent movement of the piece down a diversion shoot automatically returns the flap and opens a passage through the main shoot for normal weight pieces. Movement of the piece off the conveyer 12 into the shoot 32 pivots a second lever 17a which moves arms 21, 21a back into engagement with the finned bar so again locking the scale.

Title: Improvements relating to the sterilization of hypodermic syringes
Inventor: EVERETT SAMUEL JAMES
IPC: A61L2/06
Filed: 1959-01-30
Abstract: 894,854. Sterilizing particles and containers therefor. EVERETT & CO. Ltd., S. & R. J. Jan. 29, 1960 [Jan. 30, 1959; Feb. 19, 1959], Nos. 3423/59 and 5780/59. Class 81 (1). [Also in Group XVII] A method of sterilizing an article, e.g. a hypodermic syringe, by means of dry heat is characterized in that in order to prevent the escape of air during heating, and the consequent entry of unsterile air on cooling, the article to be sterilized is enclosed within a cylindrical container which is just large enough to receive the article, the container being closed at one end by a sealed lid and the body of the container having no other opening. As shown, a rigid container intended for the sterilization and subsequent storage of a hypodermic syringe is in the form of a cylindrical can with a lid 4 having a deep flange 5 which in conjunction with a ring of silicone rubber 6 of 0-section located in a groove effects an air-tight seal. A clip 10 engages the bottom 11 and top 12 of the can to counteract increased pressure in the can. In a modification shown in Fig. 3 there is provided a flexible diaphragm 15 of silicone rubber fitted between the end of the cap 4 and an outer cover 16 such that under the influence of internal pressure the diaphragm 15 is forced outwardly to form a visible bulge, the absence of which indicates leakage. When the assembly cools again, the diaphragm should return to its initial position as shown in Fig. 3 but if there has been any leakage, it will not return fully and the leakage is thus further indicated. According to Provisional Specification a preliminary pressurization of the container may be effected before sterilization takes place by introducing a measured quantity of ether before the vessel is sealed which causes the diaphragm to bulge slightly and during sterilization the convexity of the bulge increases then on cooling returns to its initial shape, any decrease in the degree of bulge indicating a leakage. According to Provisional Specification the addition of a small amount of sterilizing gas such as ethylene oxide enables considerably lower temperatures to be used for sterilization.
