Title: Arrangement for controlling the progress of deep-well drilling
IPC: E21B44/00
Filed: 1957-11-08
Abstract: 861,606. Boring earth. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Nov. 8, 1957 [Nov. 12, 1956], No. 34872/57. Class 85. Deep well drilling rig, in which the drill bit 4 is driven by an electric motor 3 mounted at the lower end of a drill pipe 2 suspended from a winch 7, is controlled by circuits so interlinked that the rate of drilling is automatically adjusted to an optimum value. Liquid to wash out the cuttings is supplied to the pipe 2 by a hose and pump 8. Preferably the winch 7 is electrically driven. The difference between the desired torque and the actual torque at any given moment is fed through a circuit a to a regulator 15 which automatically controls the drive of the winch 7 to change the pressure of the pipe 2 on the drill and so restore the torque to the optimum value. A circuit b includes a regulator 17 responsive to the rate of drilling to vary the output of the pump 8 supplying water to the pipe 2. When the pump reaches its maximum output, the circuit b is put into reverse and used to regulate the rate of drilling. The optimum torque of the motor, which depends on the characteristics of the motor, is fed to an adjusting device 10 while the actual torque at any given time is fed to a converter 11, the difference between the two torques being determined by a device 14 in circuit with the regulator 15, which, if the working torque is too great, increases the torque on the winch to relieve the load on the drill bit and vice versa. The devices 10, 11, 14 and 15 maybe operated by D.C. The speed v at which the drill descends is recorded by a converter 12 and compared in a device 171 with the quantity of liquid fed by the pump 8, this quantity being measured and conveyed by a device 13, which feeds the device 17<SP>1</SP>. The difference recorded by the device 171 is fed to the regulator 17 to change the output of the pump. When the output reaches its maximum a contact 8 closes and the rate of drilling is then controlled by the pump output. Variation in the output takes effect at the drilling bit with a time lag dependent on the length of pipe. This is compensated through a connection e from the regulator 17 to the servo-motor of the winch 7. A circuit d feeds the torque adjustment from the regulator 17 to the adjusting device 10. The liquid output is connected through a regulator 16 and a circuit f to the drive for the winch. The system may be operated using D.C. voltages as measuring means and to control values. The rate of drilling is determined by coupling a tachometer to the pulleys carrying the cable 5. Electromagnetic, hydraulic, electro-hydraulic or electro-pneumatic regulating systems may also be used.

Patent GB-991846-A (GB)
Title: Electron-beam production of printed circuits
IPC: H01J37/317
Filed: 1963-09-12
Abstract: A printed circuit is made or repaired by coating an insulating base of e.g. polystyrene, polyethylene terephthalate or an epoxy-glass laminate with a layer of metallic material, e.g. zinc or copper oxide and passing a beam of electrons over a predetermined portion of the layer to cause it to fuse and form an electric conductor.  The layer may be applied by spraying, brushing or dipping a slurry of copper oxide in the sodium salt of carboxy methyl cellulose dissolved in ethyl alcohol, by sifting a dry layer of the material on the insulating base and removing excess with a knife, by positioning a foil on the base or by chemical, vacuum or electro-disposition. Excess material is removed after fusing by washing or by brushing or when a foil is used by peeling off the excess foil.  The fusing may take place in vacuum and the worktable, on which the insulating material rests, may be moved automatically under the control of a computer. Conductors may be formed on several surfaces and the base may be rotated to form a continuous conductor.

Title: Method for preparing a liquid oxygen explosive
Inventor: JNR FREDERICK L SHEA
IPC: C06B43/00
Filed: 1956-11-26
Abstract: Carbon suitable for immersion in liquid oxygen, liquid air or liquid ozone to form an explosive, is produced by heat treatment of a bituminous material which is solid at ordinary temperatures and expands and becomes plastic on heating.  The bituminous material is finely ground and is first subjected to a flash-calcination in an atmosphere containing oxygen in such amount that at least 10 per cent of the evolved combustible volatiles remain unburned.  The solids are then separated from the gaseous and vaporous products at a temperature not less than that required to maintain substantially all the vaporous products in the vapour state, and, finally, the solids are heated to reduce their volatile content to less than 5 per cent by weight.  By "flash-calcination" is meant a very rapid upheat rate, i.e. in excess of 2000 DEG  F. at the surface of the particles, in a reactor maintained at a temperature sufficient to ignite the particles. A temperature in excess of 1250 DEG  F., and preferably between 1350 DEG  and 1650 DEG  F., is mentioned.  In an example bituminous coal having a volatile content of 16.75 per cent, and ash content of 4.3 per cent, was milled so that 75 per cent passed a 200 mesh.  The first stage reactor was pre-heated to a temperature of 1377 DEG  F. by burning gas supplied to auxiliary burners in the reactor.  A stream of the coal was then fed into the reactor at a rate of 177 lbs. per hour.  The maximum temperature in the first stage was 1612 DEG  F., the minimum temperature in the second stage was 805 DEG  F., and the maximum temperature in the third stage was 2394 DEG  F.  Based on the dry weight of feed to the first stage a yield of 53.7 per cent. of a hard granular absorbent carbon was obtained, having an ash content of 5.8 per cent, a volatile content of 1.18 per cent and a bulk density of 13.3 lbs. per cubic foot.  On immersing a 2 oz. sample of the carbon, contained in a fire-resistant cotton bag, in liquid oxygen for 10 minutes the initial oxygen to carbon ratio was found to be 4.1 and on allowing the oxygen to evaporate it took 11.8 minutes for the oxygen to carbon ratio to decrease to 2.0.  The impact required to accidently detonate the composition was 1465 foot lbs.  On capping at both ends a 1 1/4 inch diameter pipe and drilling various diameter holes in one of the caps, it was noted that on igniting a slow burning fuse contained in the pipe with the explosive mixture, detonation failed to occur using an orifice of 1/4 inch in diameter.  The detonation velocity of the explosive was found to be 15,800 feet per second.  Reference has been directed by the Comptroller to Specification 786,207, [Group XII].
