Abstract: 1,229,151. Wells &c. JOINT COAL BOARD. 14 Jan., 1969 [19 Jan., 1968], No. 2216/69. Heading E1F. Apparatus for orientating cores and for surveying boreholes comprises a receptacle 7 ontaining a first liquid, a chamber 15 containing a second liquid, a non-return valve 6 separating the receptacle and chamber, and a member 5 to inject the second liquid into the tube to gel the first liquid. Except for a magnet 8a carried by a float 8 in the receptacle the apparatus is non-magnetic, the apparatus being housed in a non-magnetic length of drill string positioned between the core barrel and the string proper. When the apparatus is assembled for orientating cores datum lines on the receptacle, the body 1, the mounting 11 for the apparatus, and the coupling (12, Fig. 1 not shown) connecting the apparatus into the non-magnetic length of string are aligned. After the core has been drilled, torque is removed from the string by rotating it without feed, the barrel is pressed hard on the hole bottom without rotation, the drilling fluid pressure is increased to compress air trapped above a piston 3, and the pressure is abruptly decreased to cause the piston to move the member 5 downwardly to inject the second liquid into the receptacle to fix the magnet and the meniscus of the mixed liquids. The string is raised to take the core, and the rods of the string are removed until the part housing the apparatus reaches the surface. Before the part is disconnected the datum line on the coupling is projected onto the bottom of the barrel and the core, and the core orientation is established by reference to the float in the tube. When the apparatus is used for survey only, the datum lines need not be aligned, the inclination of the hole being read from the meniscus and the azimuth obtained by measuring the angle between a line through the high and low points of the meniscus and the line joining the poles of the magnet. When used with wire line core barrels the apparatus is coupled to the barrel by a length of non- magnetic material.

In a process where iron oxide-containing masses are chlorinated (in chamber 2) with HCl or NH 4 Cl and the resultant iron chloridecontaining masses are contacted with oxygencontaining gases at 400-650‹ C. (in chamber 3) to form Cl 2 , blockage of the gas outlet (7) is prevented by contacting the chlorine at said outlet with a stream of cooler granular particles which scrape the outlet, thus removing both deposited iron chloride and iron chloride which condenses on said particles. Specified granular particles are siliceous sand and the dechlorinated reaction masses. In an example, the chlorine gas is withdrawn from the centre of chamber 3 by means of a tube which opens rear outlet 7. The reaction mass may have a size of 100- 8000 Á and the cooler particles may be at 400‹ C. Blockage prevention in this way may be applied in 3-step processes (reduction-chlorinationoxidation) or 4-step processes (reductionchlorination-pre-oxidation-oxidation).

In a gas blast switch of the kind having the interrupting chambers 1 and an operating pressure-gas container 2 located at high potential and connected by way of the supporting insulator 3 to a pressure-gas storage container 6 located at earth potential and containing gas at a very much higher pressure than the container 2, the connection is made through a small intermediate reservoir filled with sufficient gas at the higher pressure to restore the pressure in the container 2 ready for a second interruption quickly following the first but itself more slowly refilled from the storage container 5. The arrangement reduces pressure surges in the container 2 and insulator 3 which would otherwise be produced by the insufficiently fast action of a valve 9 controlling the flow of gas into them to restore the operating pressure. The valve 9 is electromagnetically operated under the control of a pressure responsive switch 8. It is bypassed by another valve 14 responding only to small pressure drops due to leakage or normal load interruptions and which has a much smaller opening. Another valve 10 which is slow acting connects the reservoir 7 to the storage container 6. Throttles 11, 12 which may be formed by the valve openings or separately prevent the direct flow of gas between the containers 6, 2.
