Patent GB-822363-A (GB)
Title: Process for the manufacture of diamond from graphite
Inventor: TILBURG JAN VAN
IPC: B01J3/08
Filed: 1956-08-24
Abstract: A target 5 containing graphite is transformed wholly or partly into diamond by high pressures generated directly or indirectly by the explosion of a charge 1.  The target is secured in a housing 4 by a nut or plug.  The shaped <PICT:0822363/III/1> <PICT:0822363/III/2> charge of Pentolite has a conical liner 2 which may be partly or wholly of graphite or of metal, e.g. copper and is detonated by a booster 3.  Alternatively, the target has a hole to set up resonance effects which produce extremely high temperatures.  The explosive may comprise a thin conductor 15 which may be of graphite or metal or graphite with a metal core and which is connected to a capacitor which is discharged to produce the explosion.  The target 21 containing graphite surrounds the conductor inside a steel housing 18.  To aid the formation of diamond crystallized seeds such as splinters of diamond or substances structurally related to diamond are embedded in the target.  The process may take place in a vacuum, in a gas or air. External pressure may be applied to the target and the target may be preheated.  Several jets from explosives may be used.  Carbon from the aliphatic groups is used in the target together with suitable mineralisis such as borates, fluorides and chlorides. Diamonds harder or less hard than natural diamonds may be produced by this process.

IPC: D01H7/04
Filed: 1967-06-07
Abstract: 1,189,987. Spindle arrangements. SPINDELMORTOREN-UND MASCHINENFABRIK A.G. 7 June, 1967 [10 June, 1966], No. 26197/ 67. Heading DID. A spindle 10 is mounted at its bottom in a radial bearing 15 in a flexible sleeve 17 and at its top by axial and radial bearings 13, 14 mounted in the sleeve 17 at the same height as the whorl. The sleeve is made flexible at its top by slots or by a flexible mounting (Fig. 4, not shown) and its bottom is located in stabilising means 23. As the axial load of the spindle is taken solely by the bearing 13 the neat generated by friction in the bearing 15 is less and the viscosity, and hence the damping effect, of the stabilising means is less liable to change during operation.

Abstract: 853,503. Piercing rock. UNION CARBIDE CORPORATION. July 31,1959 [Aug. 22, 1958], No. 26275/59. Class 68(1). [Also in Group XI] Apparatus, for thermally piercing an elongated and substantially vertical hole in a mineral body, comprises a suspended, non-rotating, elongated blowpipe housing 12, fuel and oxidant conducts F,O fixed to and extending into the housing 12, and a rotatable burner 16 mounted in the lower end of the housing and having an entrance bore 30 in receiving relation to the conduits. The burner may be rotated by water or air power, but as shown an electric driving means 13 is provided comprising a cable 52, stator 48 and a rotor 50 on a hollow shaft 44 revoluble on the outer one of two concentric conduits 18, 22 for the fuel and oxidant. The shaft 44 drives a shaft 46 through an epicyclic reduction gear 54, a reduction from 3000 to 25 r.p.m. being mentioned. The fuel, preferably kerosene, is projected through radial parts at the end of the conduit 18 and is projected, with the oxidant passing down the annular space between the conduits, into the combustion chamber 34, the combustion products passing out through an axial downwardly directed nozzle (not shown) and inclined nozzles 36 into contact with the rock. Water, admitted at W to the housing 12, passes through the jacket 24 and cooling passages 40 in the combustion chamber wall, to a space 41 from which it flows through cooling passages 42 in the burner tip. The water is discharged radially, either horizontally or in an upwardly inclined direction, and is flashed into steam by the rearwardly moving flame backwash and by contact with the spalled off rock particles. The blowpipe may be continuously reciprocated by the cable. When a necked in portion or plug of material is met, the reciprocations may be altered, ie, between 30 to 60 cycles per minute, and the stroke may be varied from 2 inches to 2 feet; which enables the plug to be removed partly by mechanical impact.
