Abstract: ABSTRACT          Process for direct drilling heavy or compacted soil comprising first killing the weeds and thereafter drilling into sub-stantially undisturbed soil;  wherein the porosity of the soil is improved before drilling by making a series of adjacent substantially parallel diagonal cuts therethrough to fissure the body of the soil without substantial disturbance of the surface.  Also claims a blade for carrying out such fissuring with a hinged extension on the trailing edge set at an adjustable angle to increase the soil fissuring as required according to soil type.  Crumble rollers may be located between adjacent blades to provide impact blows or pressure upon the temporarily raised soil lifted up by the soil-fissuring blades. Alternatively angled cutting knives on rotating shafts may follow the fissuring blades.

Abstract: ABSTRACT         A unitary optical cable is disclosed which comprises a self-sustaining tube of elastic material enclosing one or more fibers and having an inner wall of a diameter larger than the diameter of a circle circumscribing the fiber or fibers so that the fiber or fibers are free to move within the tube.          The element differs from prior art optical cable elements in that it has a longitudinally extending cut therein which extends from the outer surface of the tube to the inner surface of the tube.  This cut provides a pair of tube wall edge faces at opposite sides of the cut.  The resilient nature of the tube is such that it inherently presses the edge faces of the tube wall against one another and assumes a tubular cross-section of a diameter larger than the diameter of a circle circum-scribing the fiber or fibers.  These cable elements are useful in the construction of telecommunication cables.

Abstract: K. HILDING BROSENIUS                     TEK-4 HOT WATER HEATING SYSTEM WITH IMPROVED TEMPERATURE CONTROL               ABSTRACT OF THE DISCLOSURE         The heating system includes a radiator, a source of hot water, and a pipe circulation system interconnecting the radiator and the source. The circulation system includes a source bypass section for recirculating to the radiator that portion of the water not returned to the source for reheating.  A valve is provided for controlling the portion of water returned to the source, in accordance with the temperature thereof.  A sensor detects the temperature of the circulating water at a point between the radiator and the bypass section and regulates the valve accordingly. More of the energy in the circulating water is utilized and the efficiency of the source is maximized by maintaining the temperature of the water returned to the source for reheating at a low level.

Abstract: ABSTRACT OF THE DISCLOSURE     Data for providing spatial and shading correction error signals during the operating mode of a television camera are taken from a two dimensional array of correction points distributed across a television image during the camera set-up mode and are stored as 8 bit words.  The error correction signals extend smoothly (linearly) between the correction points.  The smoothing is performed by selectively interpolating selected reference points on each video line to provide values which vary smoothly from one row of correction points to the next.  A vertical interpolation circuit performs a vertical interpolation on a line-by-line basis, by adding signals produced by a multiplying D/A converter when loaded with the two values to be interpolated and weighted by factors related to the distance from each correction point.  The results of the vertical interpolation circuit are fed to a horizontal interpolation circuit which ramps linearly from one reference point to the next, to provide the spatial and shading error correction output signals.

Abstract: ABSTRACT OF THE DISCLOSURE         The process for preparation of support tooling for extrusion dies leads to substantial reduction in machining by utilizing a precision full mould casting method in which a destructible pattern is adjusted for shrinkage and provided with a die orifice opening staged up in size to suit the particular support role of the tooling as in a backer or bolster. This is significant because such support elements are regarded as one-of-a-kind structures.  Finished machining and treatment requires minimal time and at substantial energy reduction.  The pattern is prepared from a destructible or vapourizable plastics material replaced by the molten metal conforming to the mould configuration.

Abstract: AGRICULTURAL IMPLEMENT AND DEPTH CONTROL THEREFOR    Abstract of the Disclosure A depth control system for a disk tiller or similar ground-working implement having a gang of tillage tools adjustably supported from a main frame.  A trailing support arm is rigidly connected to the gang and pivotally carries a gauge wheel spring-biased into engagement with the tilled soil.  As the depth of the tools varies with changing conditions, the support arm moves and the gauge wheel pivots with respect to the arm to rotate a first lever.  The first lever is operably connected to a second lever by a pair of pretensioned springs.  Movement of the second lever moves a switch activating arm which activates one of a pair of microswitches.  The microswitches control solenoid valves to operate a depth control cylinder for the gang and maintain the desired depth of cut.  The switch activating arm is dampened by a dashpot which, together with the springs, prevents switch activation during short periods of oscillation.

Abstract: Abstract of the Disclosure A process is provided for the production of chemimechanical pulp in the absence of silicate stabilizers.  This chemimechanical pulp is characterized by (1) a pulp yield of at least 80% based on dry chips, (2) strength properties as shown by a combination of tear, burst and tensile properties which are superior to refiner mechanical pulp, and, (3) bleaching properties as shown by brightness properties which are superior to both refiner mechanical pulp and cold soda pulp. The chemimechanical pulp is prepared by impregnating hardwood chips with an alkaline peroxide liquor.  The alkaline peroxide liquor is an aqueous solution containing about 0.5% to about 4% hydrogen peroxide and about 2.5% to about 10% sodium hydroxide based on dry chips.  The impregnated chips have a pH greater than 7.5.  The thus impregnated wood chips are then held for about 3 minutes to about 3 hours to soften and bleach the chips after which the chips are acidified to a pH of 7.5 or below by the addition of an acid material and thereafter defibrated by passing the acidified chips through refining apparatus operated at atmospheric pressure.  The pulp produced by this defibra-tion is recovered from the refining apparatus.
