Title: Improvements in & relating to apparatus for moulding crucibles and the like
IPC: B65D83/02
Filed: 1925-03-16
Abstract: 231,470. Porter, C. T., (Assignee of Porter, H. E.). March 25, 1924, [Convention date]. Moulds ; pressing plungers; moulding hollow. ware.-In apparatus for moulding crucibles &c. of the type comprising a relatively rotatable mould and punch, means is provided whereby a substantially uniform pressure is exerted over the whole of the plastic material. As shown, the mould comprises three sections 54, 56 hinged together and held by a two-part chuck 23 carried by a table 25 rotatable through gearing 33, 34 controlled by a clutch and lever 50. Rising of the mould is prevented by flanges 53 on the mould engaging undercut recesses 52 in the chuck sections. The punch 63 comprises a flexible member of india-rubber &c., expansible laterally within the mould, carried by a headl 66 attached to a sleeve 17. Tapered ribs within the member 63 engage corresponding grooves in members 62 adapted to be expanded by a spider 60 attached to the lower end of a shaft 21 passing through the sleeve 17. Within the lower part of the member 63 is a tapered member 107 perforated centrally to accommodate a sleeve 110 attached to a lower member 109 which is depressed by the spider 60 through the sleeve 110. A spring valve 113 is housed in the sleeve 110. The upper end of the shaft 21 is attached to a piston working in a pneumatic cylinder controlled by a lever 125 and cock 121. A bridge member 15 is furnished with a guide 16 for the sleeve 17 which is prevented from rotating by screws 74 engaging grooves 76. The shaft 21 and sleeve 17 are connected by toggles 82, 83. In operation, the mould is assembled and positioned within the chuck and the correct quantity of material introduced after which the punch is caused to descend into the rotating mould' by operation of the lever 125. The shaft 21 and sleeve 17 descend together until lock-nuts 93 on the sleeve 17 engage the bridge 15. The toggles 82, 83 are then broken by operation of a lever 96 attached to a plunger 94 adapted to engage lugs 91, 92, and the shaft 21 descends further causing expansion of the punch. A spring catch 101 holds the sleeve 17 in its lowered position to permit of collapse of the punch on reversal of the piston after the moulding operation and is released by a lever 103 after which the shaft 21 and sleeve 17 ascend together. Fixed cams restore the toggles to the position shown at the end of the upward movement. The punch may be expanded by fluid pressure. To prevent rotation of the material, the mould section is polygonal.

Abstract: 1392175 Injection moulding C AUSTIN 13 March 1972 [19 March 1971] 7382/71 Heading B5A [Also in Division B1] An injection moulding machine comprises sources of supply of resin and reinforcing fibre and means for feeding resin and fibres at controlled rates to a mixing chamber 9 leading to an injection cylinder 20, this cylinder containing a piston 27 which is reciprocated repetitively so as to inject the mixture into a mould 23, 26 in a series of pressurized charges. The mould is thus filled and uniform distribution of resin and fibres maintained. As shown, the resin is supplied from a hopper 1 containing a mixing assembly 6 and a feed screw 7 and connected to the mixing chamber 9 by a passage 8 containing a valve 36. Glass fibre is fed from a reel 19 through a passage 18 to a chopping device 15 comprising a rubber covered roller 16 and a second roller 17 provided with steel blades. The mixing chamber 9 contains a mixing screw 10 which is moved axially by a piston 12 to feed resin fibre mixture to the injection cylinder 20. Rotation of the screw mixes the fibre and resin, and the screw moves upwardly as the mixing chamber 9 fills up until a microswitch 34 is actuated thereby closing the valve 36 and stopping the driven roller 16 or 17. The injection piston 27 is reciprocated by a double acting piston/cylinder 29, 30 at a rate of between 0À5 and 20 cycles per second, and preferably between 1 and 10 cycles per second. Microswitches 31, 32 control reciprocation of the piston 29. Alternatively the piston 27 may be reciprocated mechanically and means may be provided for altering its speed and stroke.

Abstract: 768,197. Measuring the inclinations of vehicle road wheels. NILSON,AKTIEBOLAGET. E. March 15, 1955, No. 7574/55. Class 97(2) In order to determine the camber, castor and king pin angles of the steering road' wheels 'of motor. vehicles, a rigid frame is arranged to hang from a hook on the tyre so that it rests against the outside of the tyre and so defines the plane of the wheel, the frame having means for measuring its inclination and changes in its inclination with respect to the vertical. Preferably, a single hook 6 is so shaped as to hang on the inside edge, of the upper surface of the tyre so that the frame 1, in its position of rest, has a three point engagement with the outside of the tyre. In the form shown, a pendulum 8 having a scale 13 co-operating with pointer 12, adjustable on guide 10 for measuring the king pin angle, carries another pendulum 17 and scales 21, 22. The friction between pendulum 8 and the member 11 of the frame 1 makes it necessary to have a spirit level (not shown) attached to scale 13 in order to indicate when the pendulum 8 is vertical. Pointers 24 on pendulum 17 move over scale 21 measuring the camber and scale 22 which is movable by screw 23 to measure the castor angle. The measurements of the king pin and castor angles, which necessitate turning the vehicle wheels, can be made concurrently. The part 5 of the frame 1 is adjustable by screw 7 in the sleeve of hook 6 for different sized vehicle wheels. Pendulum 17 may be a weighted steel band which may be supported in a ball bearing.

Title: Process for the preparation of purified solutions of the callicrein inactivator
IPC: C07K14/81
Filed: 1960-03-08
Abstract: A callikrein inactivator free from antigens and pyrogens is obtained by extracting comminuted animal organs containing the callicrein inactivator (i.e. lymphatic and parotid glands liver, spleen pancreas and lung) with an aqueous solution of a salt or hydroxide of an alkaline earth metal or of an alkali metal, ammonium or magnesium. Typical salts are calcium chloride, magnesium chloride, strontium chloride, barium chloride, calcium hydroxide, sodium chloride and ammonium sulphate.  Preferably, the aqueous extract solution contains a water-miscible organic solvent such as methanol, ethanol, propanol and dioxane.  The extract is treated with a ketone, e.g. acetone in the presence of a finely divided inert carrier, e.g. kieselguhr to preceipitate the active material which is dried and extracted with water.  Proteins are precipitated from the aqueous extract by the addition of a protein precipitant especially sulphosalicylic acid and excess precipitant is removed from the clarified solution by the addition of ion exchangers batchwise, e.g. cation exchange resin in H+ form, e.g. Amberlite IR-120, followed by anion exchange resin on (OH) cycle, e.g. "Amberlite IRA-400" (Registered Trade Mark).
