Abstract: ABSTRACT      A thermal acidization and recovery process for increas-ing production of heavy viscous petroleum crude oil and synthetic fuels from subterranean hydrocarbon formations containing clay particles creating adverse permeability effects is described.  The method comprises injecting a thermal vapor stream through a well bore penetrating such formations to clean the formation face of hydrocarbonaceous materials which restrict the flow of fluids into the petro-leum-bearing formation.  Vaporized hydrogen chloride is then injected simultaneously to react with calcium and magnesium salts in the formation surrounding the bore hole to form water soluble chloride salts.  Vaporized hydrogen fluoride is then injected simultaneously with its thermal vapor to dissolve water-sensitive clay particles thus increasing permeability.  Thereafter, the thermal vapors are injected until the formation is sufficiently heated to permit increased recovery rates of the petroleum.

Abstract: TITLE       AN ALTERNATING CURRENT COMPARATOR BRIDGE               FOR RESISTANCE MEASUREMENT                        INVENTORS                       William J.M. Moore Norbert L. Kusters ABSTRACT OF THE DISCLOSURE              The ac current comparator bridge measures the resistance of an unknown resistor at 50-60 Hz with an accuracy in the order of 10 parts per million.  The current in the unknown resistor is compared, using a current comparator, to the current in a reference resistor for the in-phase component, and to the current in a reference capacitor for the quadrature component or phase defect.          Once an ampere-turn balance is achieved in the comparator by adjusting the winding turns, the unknown resistor's values are a function of the reference resistor, the reference capacitor, the voltage sources driving the currents through the unknown resistor and the references, as well as the turns of the windings.

Abstract: ABSTRACT A spiral separator for wet separation of minerals is described.  The separator includes a vertical column around which extends a helix formed of many turns joined to the column.  A trough or channel extends down the helix and at the top end this channel is relatively narrow and deep.  This channel becomes pro-gressively wider and shallower.  It is found that the rapid flow of the pulp into the deep and narrow channel ensures that the coarser and/or less dense particles such as asbestos or coal, is maintained in suspension without any tendency to stranding of the particles, and the gradual or progressive widening of the channel and decreasing of its depth, facilitates the finer and/or denser particles moving toward the inner part of channel after being initially evenly dispersed throughout the pulp.  At the same time the coarser and/or less dense particles may be retain-ed in the outer part of channel. Some way down the channel the radial inner wall of the channel becomes a partition separating the channel from an inner helical trough.  The partition has regular openings so that denser or finer minerals trav-eling close to the outside of the partition will pass into the inner trough.

Abstract: Abstract:          A capsule of hardenable grouting adhesive material has a casing which, over a length of at least 1.0 times the diameter at a leading end of the casing, is sufficiently strong to prevent excessive distortion of the capsule when the capsule is projected into a drillhole at a velocity of 12 metres per second, and has at least one radially expansible portion extending over a length of at least 0.6 times the casing diameter which is expanded radially into engagement with the drillhole wall when the capsule is projected into the drillhole.  The preferred capsule casing comprises a continuous tube of flexible material e.g. plastics material, partially reinforced by an adhered external layer of reinforcing material e.g. paper or plastics sheet. The invention facilitates loading of capsules into drillholes in mine roofs by projection from a remotely controlled pneumatic loading machine and prevents the loaded capsules falling out of the drillholes.

Abstract: PRODUCTION OF CALCIUM CARBIDE            ABSTRACT OF THE DISCLOSURE            The invention relates to a process for making calcium car-bide by reacting an excess of coke with quicklime in the presence of oxygen in an oxygen-thermal furnace. To this end, the invention provides for precrushed coal to be used as starting material for coke and precrushed lime hy-drate (Ca(OH)2) or  precrushed limestone (CaC03) to be used as a starting material for quicklime. The precrushed mate-rials are mixed and the resulting mixture is introduced into a drying zone andand freed therein at 80 to 120°C from adhering water. Next, the warm mixture coming from the drying zone, and air, are introduced into a calcining apparatus in which the coal constituent is coked and the lime constituent is simultaneously dehydrated or decarbo-nized, at temperatures of 900 to 1400°C. The thermally-pretreated mixture of starting materials with an inherent temperature of 900 to 1000°C is  then directly introduced into the oxygen-thermal furnace and reacted with oxygen to calcium carbide.

Abstract: ABSTRACT OF THE DISCLOSURE         A flexible terminal point, especially for lattice work constructions comprising a tube formed terminal means, which is secured to the disc formed or shell formed bars, and which at its one end receives the bar in a manner which allows limited flexibility. Through the tube-like terminal means runs one or several tie-rods, by which the terminal means is attached to the bar, and by which the terminal means can be pretensioned, whereby load changes in the bar only to a lesser degree cause strain changes in the tie-rod while the major part of the loads in the bar is taken up by the tube-like terminal means which is set under compression forces.  Coupling between terminal means and the movable bar is effected by means of a bearing socket via a rubber pad or spherical surfaces in the terminal means and movable bar.  The tie-rod can be formed as one or several tie-rods, steel cables, wires or such, which can be tensioned and locked by known methods for pretensioned constructions.

Abstract: ABSTRACT OF THE DISCLOSURE A ball valve is turned relative to its seat by means of three concen-tric sleeves mounted within a housing bore.  Pins carried by the middle piston sleeve extend outward into slots in an outer carrier sleeve and inward into cam grooves in the outer wall of an inner drive sleeve.  Axial movement of the middle sleeve under hydraulic pressure causes turning movement of the inner sleeve which then drives through bevel gears to turn the ball valve.  The parts are construc-ted so that hydraulic forces within the housing acting to hold the ball valve in closed position against its seat are substantially balanced by forces in the op-posite direction acting against the outer sleeve.

Abstract: Abstract of the Invention The invention relates to a sample support as part of a photometric or fluorometric apparatus.  According to the prior art two separate devices are required.  Modification to convert a photometer into a fluorimeter and vice versa is laborious.  This has resulted in the development of many different designs of both photometric and fluorometric apparatus specifically for one object.  The aim of the invention is therefore to provide a sample support which enables virtually any of the investigations in question to be carried out if required - independently of the type of basic apparatus used - by simple manipulation or modification.  The solution according to the invention provides a sample support in the form of a block unit which is intended to receive cuvettes or test strips and is fitted with slide-in holders for different filters and contains a reflectance deflector which guides the light or fluorescent radiation to the detector.  By the simple conversion of standard commercial apparatus it is possible to modify the actual specifications of the basic apparatus so that a broader spread of different analyses can be carried out in substantially standard basic apparatus.

A gas vent is located at the highest point in the top wall of the housing, which is at the center of the top wall.  The liquid inlet and filter element cap are designed to provide for establishment of a stable swirling flow outside the filter element and above the filter element cap. An improved means of bonding upper and lower cup-like portions together to form a hollow tubular housing with high resistance to rupture under pressure is also disclosed.  The filter of the invention is particularly suited for use in extracorporeal blood flow circuits, most particularly as an arterial blood filter located downstream from a blood oxygenator.
