Patent GB-2009473-A (GB)
Title: Borehole while drilling
IPC: E21B47/01
Filed: 1978-12-04
Abstract: Pulses generated, in response to parameters sensed down a borehole, by rapidly opening and shutting a valve in a comparatively wide bore passage which by passes the drill head or hydraulic motor which restricts mud flow in the borehole arrive a receiver in the high pressure side of the mud flow path positioned at the earth's surface and equipped with means to eliminate from the received signal the "noise" which is due to pressure variations arising from pulses due to the drilling mud pump. The valve used to open or close the bypass is almost balanced by opposed pressure faces but is biassed by pressure bistably to its open or closed position such that only a very small driving force from a driver is required to drive it. Hence a downhole driving power source may be provided to have a life at least equal to that of the drill head itself. The power source may include a molten salt battery or an electrolyte battery specially adapted for operations under high pressure temperature conditions by being held in a container in which there is also enclosed a source of balancing pressure.

Title: Hydro-mechanical variable-speed gear
IPC: F16H47/04
Filed: 1979-01-19
Abstract: In an epicyclic gear including a first axial shaft 6 coupled to a planet carrier 7, a sun wheel 9 coupled to a second shaft 11 co-axial with the first and an annulus 12, one or more screw- type hydrostatic pumps 13 are driven by the annulus, while a plurality of screw type hydrostatic motors 14 are driven by the planet carrier, and control valve means selectively controls the supply of fluid to the motors from the pump(s), a pressure relief valve being provided in the fluid circuit. By selective operation of the motors through the control valve means, a variety of speed ratios can be chosen. This transmission system does not require a torque converter, and considerable operational cost savings should arise where the system is to operate at reduced speeds for considerable periods. The system could serve as either a step-up or a step-down transmission by having the input through the first shaft 6 or the second shaft 11 respectively. <IMAGE>
Patent GB-2022146-A (GB)
Title: Surface hardening
IPC: C21D5/00
Filed: 1979-05-08
Abstract: In a method for the surface hardening of a metal workpiece wherein heat is supplied to the workpiece by means of a moving energy beam, e.g. an electric arc, which melts the surface at the moving point of contact, the cooling of the workpiece by heat seepage to the interior of the metal surface results in the formation of a hardened surface. However as the movement of the energy beam proceeds, the metal body progressively becomes hotter, so that the depth of the outer hardened zone increases. The invention corrects this feature by decreasing the supply of melting heat to the workpiece whereby a final hardened layer of constant thickness is obtained. The variation in the supply of melting heat may be achieved by increasing the relative motion of the energy beam and the workpiece, e.g. by increasing the movement of the workpiece past the energy beam, and/or increasing the motion of the energy beam, and/or reducing the power of the energy beam. The invention is of particular application to the surface hardening of cast iron e.g. to cast iron camshafts. <IMAGE>

A double throttle/check valve (27) is mounted in series with the pressure regulator valve to provide selective metering or free flow action of fluid in the fluid flow passage. An adjustable quick exhaust valve (35) not shown is mounted in a second parallel fluid flow passage. <IMAGE>

Title: Improving combustion in controlled flames
IPC: F23L7/00
Filed: 1979-08-24
Abstract: A means of an apparatus for improving the normal heat release and luminosity of a controlled flame is described. A flame produced by controlled burning of hydrocarbons cracks these substances into hydrogen and carbon molecules, the carbon uniting with oxygen to form carbon monoxide-carbon dioxide and the hydrogen with oxygen to form water gas. By the introduction of a catalyst the carbon and hydrogen once cracked can be influenced to reunite to form a synthetic petroleum hydrocarbon gas of the olefin Series (CnH2n), which has higher release of energy (heat, light) than any natural reaction of the flame. The catalyst is generated by bubbling an air stream through a reservoir of water with a supernatent layer of oil. The resulting air contains the catalyst in gas form and is led to the flame.
