Abstract: ABSTRACT OF THE DISCLOSURE          In a down hole drilling tool a closed valve is operatively moved downwards by pressurised drilling mud pumped down the drill string, the valve when it attains its lower position being opened and being returned under the influence of a spring or other upwardly urging means acting on the valve to its upper position at which the valve is closed thereby to complete the cycle of operations.  The valve is so contin-uously coupled to a torque member that the downward movement of the valve causes turning of the torque member in one direction, and the upward movement of the valve causes turning of the torque member in the opposite direction.  A drill bit mounted on the lower end of a rotor is connected through a one-way clutch to the torque member so that during the down-ward movement of the valve the rotor and drill bit are rotatably driven by the torque member but are stationary during the upward movement of the valve, the drill bit thus being operatively intermittently rotated,  During the upward movement of the valve the pressurised drilling mud flows through the open valve and issues from the drill bit as high pressure and volume flushing jets while the drill bit is stationary, thereby providing more effective cleaning of cuttings and chips from the bottom of the bore hole being formed by the drill bit.  Aligned annular grooves are provided in the rotor and in the housing in which the rotor is mounted, ball bearings being disposed partially in each of these grooves thereby to provide an axial thrust bearing capable of transmitting high axial thrust from the housing to the rotor and hence to the drill bit.  Lipped pockets are also provided in the rotor in communication with the grooves therein, with the ball bearings being disposed within these pockets during assembly and disassembly of the rotor and housing.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and four devices for measuring the change in mass of a sample subjected to selected temperatures and fluid variables is disclosed   The test sample is subjected to centrifugal force to amplify the "apparent mass" of the sample by rotating the sample about a first axis of rotation. Any change in the mass of the test sample is then amplified by the centrifugal force and measured by the displacement of the sample about a second axis of rotation.  The above method and four separate devices are disclosed.  The first device balances the mass of the test sample against a known reference sample.  The second device generates a counter-rotational force about the second axis to bring the sample to a "nulled" position.  The third device balances the force generated about the second axis against a known and adjustable balance beam.  A reciprocating means is used to couple the balance beam to a rotating sample holder.  The fourth device generates a counter force along the balance beam to bring the sample to a "nulled" position.  The devices are particularly adapted for mass change analysis in high temperature environments using high sweep gas rates and a variety of gaseous fluids.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the extensive removal of undesirable metal ions, particularly vanadium ions, in the course of the concentration of dilute iron(II) sulfate-containing sulfuric acid solutions.  The sulfuric acid solutions are concentrated by the evaporation of water and the separation of iron(II) sulfate to a content of 60 to 70% by weight H2SO4.          According to the invention, the content of trivalent titanium in the solution is adjusted such that the content of trivalent iron does not exceed 0.1 g/1.  The trivalent titanium may be added from the outside, if not already present in an adequate amount in the solu-tion, or may be formed in situ from the tetravalent titanium present in the solution by the addition of a reducing agent.  Prior to the final concentration, part of the iron may be precipitated and separated as iron(II) sulfate heptahydrate by means of preconcentra-tion and cooling of the preconcentrated sulfuric acid solution.

Abstract: ABSTRACT          A switch/display unit comprises a dot matrix electro-luminescent display, having two sets of parallel elongate electrodes, one set being inclined to the other, these sets being applied to opposite sides of a layer of phosphor.  A transparent dielectric panel is superimposed in front of the electro-luminescent display, so that the first set of electrodes, which are formed from a transparent conductive material abut the rear surface of the dielectric panel.  A transparent conductive layer is formed in front of the dielectric panel, so that it will capacitively couple electrodes of the first set of electrodes with other electrodes of the first set of electrodes or other electrodes on the rear surface of the dielectric panel.          This capacitive coupling may be varied by touching or moving the conductive layer.  By applying read pulses to one of the sets of electrodes that are capacitively coupled via the conductive coating and sensing the pulses transmitted to the other electrodes, actuation of the switch can be detected.  A device is also provided to apply ignition pulses to the first and second sets of the elongate electrodes, so as to provide an electro-luminescent display which may change in response to actuation of the switch.  Several such switch/ display units may be combined into an array, utilising a common dielectric panel and other components.

Abstract: VARIABLE DISPLACEMENT PUMP SYSTEM    Abstract of the Disclosure A variable displacement pump has a swashplate controlled by a pair of pistons.  A shuttle valve communicates the highest pressure pump workport to an operator-controlled displacement control valve.  A pressure-responsive override valve is connected in series between the displacement control valve and the pistons.  When an override pressure is achieved, the override valve blocks communication of the control valve with the pair of pistons and communicates the pump workports directly to the pistons for rapid destroking.  A neutral bypass valve is formed out of a sleeve of the displacement control valve to bypass control pressure to sump when the displacement control valve is in neutral.  A pressure-reducing valve limits the pressure acting on the stroke control valve to limit response rates and reduce erosion.  The override valve includes orifices which, in intermediate positions, provide flow rate control of the fluid flow to the swashplate control pistons.

Abstract: ABSTRACT     A cathode pot for the electrolytic production of aluminum has composite bodies which line the sidewalls of the steel shell (1a) and are bonded to the carbon floor elements (22) such that a seal is formed. The inner side (10) of the said composite is of carbonaceous material and the outer side (12) of a hard ceramic material. This conducts the electric current poorly but conducts heat well, is resistant to mol-ten aluminum and the prevailing atmosphere of the process, and has a coefficient of thermal expansion comparable to that of carbon.     The intimate joining together of the two sides  (10,  12) permits almost unhindered flow of heat from inside to out-side.     The composite bodies are manufactured in layers, mechani-cally compacted and baked or graphitised in packing powder.     (Figure 6)
