Title: Improvements in and relating to foundry moulding machines
IPC: B22C17/10
Filed: 1932-02-09
Abstract: 396,125. Moulding-machines. HINES, L. H., 53, Derby Road, Heaton Moor, Stockport. Feb. 9, 1932, No. 3883. [Class 83 (i).] A jar-ram moulding-machine has a plate 17 which applies a definite and, if desired, adjustable pressure to the sand each time the table 12 falls. The machine has a pressure cylinder 19, pivoted at 21 so that it can be swung aside, on a slide 22 adjustable on a turn over frame 9 which also carries the jar-cylinder 11. A flask having been placed over a pattern on the table 12 and filled with sand a handle 57 of a screwed rod 53 is moved to bring the rod into engagement with a support 46 and, by means of a cam 59, open a valve 16 which admits air to a jarring-valve 15, connected to the cylinder 11, Fig. 5, and to a cylinder 36 closing, to a degree determined by a screw 45, a valve 43 in a pipe line leading to a valve 31 adjusted to admit air to a pipe 30. Each time the valve 15 admits air to the cylinder 11 a valve 28 is also raised, against the action of a spring 39, and opens the upper end of the cylinder 19 to exhaust and each time the cylinder 11 is exhausted by the valve 15 the valve 28 falls and air is admitted to force the plate 17 down. When the sand has been sufficiently compressed the handle 57 is reversed to close the valve 16, release the support 46, and engage a rod 60 of the table 12 by a fork 58 to prevent it from moving. Cylinders 52, Fig. 1, are then operated to rotate the frame 9 through 180‹ and the valve 31 is reversed so that air is admitted to the pipe 32 and exhausted from the top of the cylinder 19 thus lowering the plate 17 and drawing the mould. During this operation a vibrator on the table 12 is actuated by air pressure. If a double-sided mould has been made the pattern on the plate 17 is first drawn the flask being supported by rods connected to the cylinder 19. Specification 384,014 is referred to.

Title: Improvements in the destructive hydrogenation of carbonaceous materials and in the recovery of oils from the residues of said treatments
IPC: C10G31/10
Filed: 1934-02-10
Abstract: The oils contained in the residues obtained in the destructive hydrogenation of carbonaceous materials are separated from the solid constituents by centrifuging the residues continuously in stages so that the oil separated in an early stage still contains a large percentage of solid material which is separated in a further stage and is returned to the first stage.  Disc centrifuges with conical walls may be used and diluents, e.g. oils obtained in destructive hydrogenation, and solids, e.g. coke dust, may be added.  The process is carried out at 60--200 DEG  C.  A residue obtained in the destructive hydrogenation of brown coal and containing 25 per cent solids is mixed with 25 per cent of a heavy oil and centrifuged at 140 DEG  C. in disc centrifuge from which the residues are discharged through nozzles in the drum wall.  The centrifuged oil is again centrifuged with a throughput of 4000 litres per hour and 3400 parts of pure oil are obtained with a residue of 600 parts which are returned to the first stage.  The residue from the first stage is subjected to low temperature carbonization.

Abstract: 818,668. Treating fertilizers with acid. DUNGEMITTEL-TECHNIK A.G. Feb. 12, 1958 [Feb. 16, 1957], No. 4639/58. Class 111. A method of treating fertilisers, phosphates and calcium cyanamide with mineral acids comprises introducing the finely ground fertilizer in continuous flow into a treatment chamber, blowing air into the chamber by means of nozzles arranged at the bottom of the chamber to create a vortex whereby the finely ground particles are held in suspension and simultaneously spraying on to the fertilizer sulphuric acid and/or phosphoric acid and/or nitric acid. Ammonia may be sprayed on to the phosphate simultaneously with the acid. Granulation of the fertilizer particles may be produced by means of an agitator device rotating in the whirling mass. The fertilizers used may be natural phosphates, phosphates produced by chemical methods, Thomas slag, calcined phosphates, aluminium phosphate and may contain powdered organic substances such as ground peat, decantation sludges, saw-dust, ground lignin. In Fig. 1, nozzles 3 in the bottom of reaction chamber 1 blow vertical jets of air from lower chamber 4 supplied with air under pressure. Fertilizer fed in at 6 is momentarily held in suspension to receive jets from nozzle 11 on pipe 10. Reaction takes place and the treated product collects in layer 18 which is evacuated through orifices 14 and 15. Blown air carrying with it water vapour and gases generated by reaction passes out at 12 to dust extractor 13. Rotary agitator 19 produces an agglomeration of the treated products in the form of granules.
