Title: Carburettor with a piston valve
IPC: F02M9/02
Filed: 1973-01-11
Abstract: 1415211 Spray carburetters P AUGUST 11 Jan 1973 [13 Jan 1972] 1569/73 Heading F1B In a carburetter having a piston valve 4, Fig. 1 and a bridge piece 5, one surface of the piston valve together with an adjacent surface of the bridge piece define a duct having a converging section and a diverging section, the duct thus having the form of a Laval nozzle. At low idling speeds fuel passes via ducts 10 and 8 into the slot 6 formed between the piston valve 4 and the bridge piece 5 to be atomized by air passing from inlet 2 to outlet 3. As the piston valve opens additional fuel passes through ducts 9. Fuel from a float chamber (not shown) passes via duct 11, jet 12 and mixing pipe 13, where it is mixed with air from nozzle 14, and the mixture passes through a convergent/divergent nozzle formed between a needle 15 and a nozzle element 16 where the fuel atomization is increased. A further cowling 17 may be fitted to improve atomization. Slot 6 may be formed partially in the piston valve and bridge piece or wholly in the latter. The main nozzle system may comprise a plurality of convergent/divergent nozzles.

Title: Improvements in or relating to anti-haemophilic globulin
Inventor: BIDWELL ETHEL
IPC: A61K38/00
Filed: 1955-01-21
Abstract: Antihaemophilic globulin is prepared by adding to the supernatant liquid obtained from bovine, pig or sheep blood plasma by contacting said plasma with aluminium hydroxide gel to adsorb the prothrombin, a phosphate or citrate in amount at least equal to but not substantially exceeding that required to produce a small but definite precipitate while maintaining the pH at from 6.0 to 7.0.  The blood, which should be as fresh as possible, may be stabilized by the addition of anticoagulants such as citrates or dextran sulphate.  The phosphate or citrate employed to precipitate the A.H.G. is preferably added as an aqueous solution buffered to the appropriate pH value. Sufficient water may be p  added to give a final volume of mixture of at least 150% of the volume of the prothrombin-free plasma.  The temperature at which the precipitation is carried out should be less than 15 DEG  C.  The precipitate may be further purified by contacting it in the solid state or in solution in saline with sodium citrate of from 7.5-8% concentration by weight and discarding the citrate soluble portion.  It is preferred to use potassium phosphate for the precipitation stage and sodium citrate for the purification.

Title: Method and apparatus for removing a settled body of aprticulate material of the type that forms a pumpable slurry with a liquid
IPC: B65G53/30
Filed: 1974-01-16
Abstract: 1461162 Unloading by currents of liquid MARCONA CORP 16 Jan 1974 [23 Nov 1973] 2023/74 Heading B8E [Also in Divisions B1 and E1] In a method of and apparatus for removing a body of material capable of being formed into a slurry, liquid stream are directed into the material from a first group of nozzles 38, 39, Fig. 8 carried in a housing 19 which is lowered into the material. The slurry thereby formed is pumped away to a zone remote from the housing by a discharge pump 104 in the housing, additional streams of the liquid being directed upwardly into the inlet of the pump from a second group of nozzles 120 in, for example, an ejector pump 114 in order to maintain the prime of the discharge pump. In the particular embodiment, each nozzle of a third group 36, 37 is longitudinally fixed relatively to the housing, while each of the nozzles of the first group is longitudinally movable (elevatable) by means of a hydraulic cylinder actuator 87, Fig. 8. Both types of nozzle 36, 37 and 38, 39 have nozzle parts 48, 64 which are swivellable through 280 degrees in a horizontal plane and are oscillated through this arc by rotary hydraulic actuators 51, 77, Figs. 9 and 10 controlled by rotary valves 56, 82. Pump 104 is driven by hydraulic rotary motor 111 of variable speed. In ejector pump 114, liquid from pipe 122 enters ring spray pipe 116, Fig. 14 and nozzles 120 direct the liquid into the inlet 118 of pump 104. In use, housing 19 is positioned on top of material 16 in a barge 17 by mobile crane 22, Fig. 1. Conduits 23, 24 and 26 are connected to an installation, not shown, for water supply, slurry discharge and hydraulic fluid supply respectively. Elevatable nozzles 38, 39 are fully raised and oscillated and the issuing streams of water are deflected downwardly by annular deflector 89, Fig. 8 and inner deflectors (92-95, Fig. 11, not shown). Pump 104 is also operated. As the legs 102, 103 of the housing 19 reach the floor of the barge 17 or any other suitable intermediate position, the nozzles 38, 39 are switched off and the fixed nozzles 36, 37 are operated without downward deflection due to their position. Ring spray pipe 116 is operated when the slurry level is low. Subsequently, and when the majority of material is removed, the fixed nozzles are closed and the elevatable nozzles lowered and operated to clean the floor and remove the remaining slurry.

Abstract: 1537321 Milling; grinding BERGMANN & STEFFEN OHG 20 Jan 1976 [30 Jan 1975] 02111/76 Headings B3K and B3D A method of machining a tube 10 having a helical weld seam 11 comprises simultaneously removing the weld head from the inside and outside surfaces of the tube. In a machine for carrying out the method, the tube 10 is held fixed by clamping claws 19 and is supported from a bed 12 by bearings 13 which may be formed of hydraulic cylinders so as to effect a cushioning to accommodate any irregularities in the tube, each bearing having an abutment member 13a. A guide block 16 is mounted for axial movement along the bed and is movable by a motor 39 driving a pinion 40 engaging a rack 41 on the bed. The guide block is formed with an annular guide groove 24 which slidably receives a guide 22 for a radially displaceable slide 21, the block also mounting a shaft 27 which is driven by a motor 28 and has a gear 26 meshing with an internal gear 25 fixed to the block 16 whereby the block is driven around the tube. The slide 21 carries a motor 20 driving a milling or grinding tool 15 which during axial movement of the block 16 and circumferential movement of guide 22 follows the helix of the weld to remove the bead from the outer surface of the weld. Simultaneously, the bead is removed from the inner surface of the weld by a milling or grinding tool 14 which is driven by a motor 25 and carried by a slide 34 adjustable along a guideway of a guide 33 on an adjusting member 31a on a bearing 31 rotatable on the free end of a screwthreaded spindle 18. The bearing has struts 30 supporting an internally toothed gear 29 meshing with a gear 38 on the shaft 37 of a motor 36 mounted on the guide 33, rotation of the gear 38 rotating the guide so that during axial movement of the spindle 18 by gearing 43, 45 driven by motor 44 rotating a nut 42 on the spindle, the cutter or grinding wheel follows the helix of the weld to remove the bead on the inner surface of the tube. The gear 29 is supported by radial rams 32 and rollers 32a engaging the inner surface of the tube. The outer cutter or grinding wheel is adjustable about a pivot 71 so that its axis is normal to the helix of the weld, the inner cutter or grinding wheel being similarly adjustable. In another embodiment, the inner and outer cutters or grinding wheel are merely moved axially of the tube and the tube is rotated. The tools are pressed against the surfaces of the tube by pressure units (20, Fig. 3, not shown), the depth of cut being controlled by feelers (69) engaging the surfaces of the tube.
