Title: Improvements in or relating to moulding apparatus
IPC: B29C44/54
Filed: 1969-03-21
Abstract: 1,261,798. Mould filling apparatus. CROWN MACHINE & TOOL CO. 21 March, 1969 [6 Feb., 1969], No. 14956/69. Heading B5A. Apparatus for filling a mould with expandable plastics beads comprises a gaseous fluid jet for conveying particulate material into a mould and supply means for moving a charge of particulate material to the jet as the cavity fills. The apparatus shown for the formation of expanded plastics cups comprises a mould cavity 20 joined to a filler cavity 42 by passage 50. A pressure chamber 34 connects the filler cavity 42 with inlet conduit 30 supplied from a hopper and flow from the hopper is controlled by valve 32. A piston 48 movable by supplying air to cavities 52 or 56 is attached to cylinder 46 which opens and closes the passage 50 and the air jet for blowing particles into the mould is supplied from inlet 54 into cavity 52 via passages 62 and 60 in the piston 48 and cylinder 46. The operating fluid is compressed air preferably at 80 p.s.i. to inlets 54 and 58 and 50 p.s.i. to inlet 36. At the start of a moulding cycle the mould is closed, plunger 46 is in its lower position and valve 32 is open so that synthetic plastics beads are. supplied by gravity to the filler chamber 42 and the pressure chamber 34. Valve 32 is then closed and valve 66 operated to force compressed air through 36 into the moulding chamber and to force air through 54 into cavity 52. This raises the piston 48 and cylinder 46 and creates an air jet from passage 60. As the piston 48 clears the passage 50 this air jet, assisted by the pressure in pressure chamber 34 forces the beads into the mould, excess air escaping through small holes (not shown) along the mould parting line 27. The air is then supplied by rotation of valve 66 to cavity 56 thereby lowering the piston and cylinder to block passage 50 and at the same time the pressure in the pressure chamber is released. Valve 32 is opened and the filling apparatus is ready for re-use when the plastics material has been moulded and the article removed from the mould.

Title: Improvements in deep boring apparatus
IPC: E21B4/02
Filed: 1926-06-18
Abstract: 275,379. Lachamp, E., and Perret, E. June 18, 1926. Borehole apparatus. -In deep-boring apparatus of the kind in which the tool is operated by a hydraulic turbine or motor disposed near the bottom of the borehole, the turbine &c. being driven by water which, on discharge, returns to the surface level outside the tubing column carrying the device, the turbine &c. and boring tool are freely suspended so that they can be raised or lowered through the tubing column, through which the water under pressure is supplied to the turbine &c. and which is held against rotation, the housing of the turbine &c. when m its lowest position, interlocking with a suitable seat within the tubing column. As shown, the tubing column 1 is suspended from a cable 4 and a motor 10 and a boring tool comprising pivoted cutters 18 are lowered through the column by a cable 11 until teeth &c. on the motor casing interlock with a toothed seat 9 in the column 1. A pump G then supplies water through the column 1 to drive the motor' and the tool, the water returning outside the column and carrying away the cuttings. Pressure of the tool on the bottom of the borehole is controlled by a device R between the motor and the tool. Such device may comprise a threaded connection 23, 21, and opposed springs 27, 28, Fig. 3, the arrangement permitting a slight rise of the boring tool on encountering increased resistance; if the resistance is such as to stop rotation of the tool, the tool rises sufficiently to cause the upper part 25 of the device R to engage a restricted part 26 of the column 1, and obstruct the flow of water, resulting increase of pressure in the column 1 then giving warning to the operator. Alternatively, the device R may comprise a cylinder 21<1>, Fig. 4, connected to the tool and slidably keyed to the motor shaft 15, and a piston 32 carried by the shaft 15, the cylinder being open to the water above the motor through passages in the shaft 15 and piston 32 ; increased resistance to the tool then causes slowing down of the motor and consequent increase of pressure above the motor which acts on the cylinder 21<1> to lift the tool. Where the motor is a turbine, means are provided whereby slowing down of the turbine through increased resistance to the tool acts automatically to reduce or stop the supply of water to the turbine. Further, the increased pressure in the column 1 may be caused to act on the suspension cable through a servo-motor.
