Title: Improvements in or relating to gantry cranes
IPC: B66C19/02
Filed: 1935-11-06
Abstract: 453,980. Portable gantry cranes. ARDELTWERKE GES., Eberswalde, Germany. Nov. 6, 1935, No. 30698. Convention date, Sept. 26. [Class 78 (iv)] A gantry crane, capable of ready assembling, dismantling and transport, comprises a main girder or bridge a all in one piece, which is carried separately by a road or rail motor or trailer vehicle b, and four legs k detachably hinged at their upper ends to the girder and at their lower ends to trolleys n running upon the usual traversing track. All the parts other than the main girder are made in detachable pieces each of which can be lifted by one man. In the erection of the crane the main bridge is positioned across the track, the parts of the legs are assembled and the completed legs hinged to the girder. After assembling these parts, a hand or power-driven winch o is used to wind up tackle p to draw the pairs of legs at each end of the girder towards one another, thus elevating the girder. Metal ties secure the legs in the supporting position. To prevent the main girder tipping sideways, the angular movement of each leg k of a pair is equalized by inter-connecting the legs through toothed gearing q. Indicators may show the angle of each pair of legs with the horizontal to facilitate equal raising of opposite ends of the girder. When working, a loadcarrying trolley c runs to-and-fro on the main girder in the usual manner. When the main girder cannot be transported on its carriage all the way to the place of use, it may be transferred to a pair of endless-track tractors h to complete the journey. When carried in a railway truck, the bridge may be swung round on a turntable before it is transferred to the endless-track vehicles.

Patent GB-886180-A (GB)
Title: Purification of fibrinolysin
IPC: C12N9/68
Filed: 1958-10-01
Abstract: Fibrinolysin suitable for intravenous injection is obtained by treating sterile human profibrinolysin in an aqueous solution at a temperature of 25 DEG C. and a pH between 6 and 7.5 with sufficient streptokinase to convert all of said profibrinolysin to fibrinolysin, cooling, acidifying to pH 1.8 to 3.5 to precipitate impurities, adding to the clarified solution a miscible water soluble organic solvent at a temperature between -3C DEG . and -7 DEG C. and allowing to stand until the fibrinolysin is precipitated.  The profibrinolysin is first sterilised by heating an aqueous solution containing less than 10% profibrinolysin and having a pH of 3.0 to 6.5 and ionic strength below 0.3 at 60 DEG C. per 10 hours to destroy hepatitis virus.  Excess streptokinase in pyrogenfree water (200,000 to 600,000 sk units) is added to the solution of profibrinolysin containing 10 to 50 m.g. per ml. profibrinolysin and allowed to stand 5-60 minutes at 25 DEG C.  After acidification and removal of the precipitated impurities, other impurities may be removed by adding methanol to a concentration of 6% by volume at -3 DEG C. to -7 DEG C.  Methanol is then added to a concentration of 60% by volume at -3 DEG C. to -7 DEG C. and is maintained at this temperature until the precipitation of fibrinolysin is complete. After washing, the precipitate is suspended in pyrogen-free water and lyophilised.  The methanol may be replaced by ethanol or acetone.  The fibrinolysin has an activity of 100,000 fibrinolytic units per milligram of nitrogen; is soluble in water and saline; free from streptokinase, prothrombin, thrombin, thromoplastin, fibrinogen and fibrin; is incapable of clotting fibrinogen or of converting prothrombin to thrombin rapidly; is not inhibited by prothrombin; is capable of destroying fibrinogen, fibrin and prothrombin (slowly); and remaining in solution without clot formation when an aqueous solution is treated with thrombin, fibrinogen or a combination of fibrinogen and thromboplastin. Specification 869,122 is referred to.

Filed: 1921-11-24
Abstract: 193,172. Juckes, T. C., (trading as Efficient Motor & Engineering Co.). Nov. 24, 1921. Channels and reservoirs in engine crank casings.-In a non- pressure lubricating system for internalcombustion engines, there is provided an intermediate reservoir from which lubricant passes to the bearings and sumps through passages which communicate with the rear part of the reservoir, so that the flow is increased or diminished according to the direction in which the engine is tilted. In an engine mounted with its shaft transverse to the line of travel, the intermediate reservoir 1, supplied by a pipe 9, is formed near the forward upper edge of the crank-case. Oil passes from the reservoir 1 through passages 3 extending across the top of the casing, and thence through passages 4 extending down through the end walls 5 to the bearings 6, from the ends of which it passes by passages 7 to the sump 8. The passages 3 lead from the reservoir some little distance above the base thereof, so that the reservoir normally retains a small quantity of oil. Oil may be pumped from the sump 8 back to the reservoir 1. In the case of a two-stroke-cycle engine, the transfer passage is arranged to open near the centre of one end of the crank-case. As shown, the transfer passage 12 is formed in two parts separated by a web 13 and extending through the ends of the crank-case to openings 14 disposed near the centre. Alternatively, the crank-shaft may be formed hollow to serve as the transfer passage, the gases passing out through the end or through holes to a passage or external pipe leading to the cylinder.
