ABSTRACT OF THE DISCLOSURE A capacitor comprising at least two electrodes separated from one another by an elastic dielectric formed of rubber and/or plastic for measuring forces acting upon one of the ¦ electrodes -- the so-called measuring electrode -- by detecting the resultant change in capacitance. The dielectric in its un-loaded state is pre-compressed and preferably possesses a number of hollow spaces. A method is also disclosed for measuring forces randomly occurring as a function of time as well as locally within n predetermined surface wherein the forces arc applied to a measuring electrode of a capacitor containing an elastomeric dielectric. The measuring electrode corresponds to the pre-determined surface. There is then recorded the change in capacitance of the capacitor and which capacitance change corresponds to the course as a function of time of the action of the force.

SINGLE WELL TRACER METHOD TO EVALUATE ENHANCED RECOVERY Abstract Data useful to evaluate the effectiveness of or to design an enhanced recovery process (the recovery process involving mobilizing and moving hydrocarbons through a hydrocarbon-bearing subterranean formation from an injection well to a production well by injecting a mobilizing fluid into the injection well) are obtained by a process which comprises sequentially: determining hydrocarbon saturation in the formation in a volume in the formation near a well bore penetrating the formation, injecting sufficient of the mobilizing fluid to mobilize and move hydrocarbons from a volume in the formation near the well bore penetrating the formation, and determining by the single well tracer method a hydrocarbon saturation profile in a volume from which hydrocarbons are moved. The single well tracer method employed is disclosed by U.S. 3,623,842. The process is useful to evaluate surfactant floods, water floods, polymer floods, CO2 floods, caustic floods, micellar floods, and the like in the reservoir in much less time at greatly reduced costs, compared to conventional multi-well pilot test.

ABSTRACT OF THE INVENTION A Doppler radar having a single sense Doppler signal from the rf mixer. A single sideband modulator in a common antenna system for transmitting and receiving shifts the fore and aft beams to achieve a single sense Doppler signal. The use of the single sideband modulator results in a differential Doppler shift between fore and aft beams of only a few hundred knots, thereby permitting use of low cost components. A sin-gle sense Doppler also reduces the Doppler passband by a 2:1 factor which permits the power supply frequency to operate at a higher frequency than the receiver.

Reposition feature for an electronic typewriter

REPOSITION FEATURE FOR AN ELECTRONIC TYPEWRITER Abstract On electronic typewriters which have the ability to record into a small working memory the escapement of the characters which are keyed at the keyboard, it is many times advantageous to be able to reposition the carrier at the rightmost end of the typed material automatically. This is particularly advantageous when it has been necessary to back the carrier up along the printed line for purposes of erasing, correcting or inserting material into that line. Disclosed herein is an electronic typewriter which is controlled by the electronic logic such that the depression of a selected control key will result in the carrier moving from a position within the typed text on a particular line to the right most position the carrier has occupied within that line during earlier typing. This is accomplished by temporarily storing the rightmost carrier position as recorded in the escapement register into a working memory and then upon the appropriate command from the keyboard, using that location in the manner that a tab stop location would be used and creating a tab like command movement to cause the carrier to go directly to that point and stop.

The base has a bore therethrough which receives the sleeve, and a slot is located parallel to and communicating with the bore. The slot has a width which is greater than the diameter of the rod and less than the outside diameter of the sleeve so that the rod can be placed into the slotted base of the hook and held in position by the sleeve which is slipped over the rod and into the bore. A projecting hook portion is integral-ly connected with the base and is used to engage the bone of the spinal column. A locking system in the form of threaded nuts engages the rod securing the position of the sleeve so that the entire hook assembly may be held in place with respect to the rod. When hooks are faced toward each other on a rod, compression is achieved by advancing the threaded nuts. Likewise, distraction is achieved by reversing the hooks so as to be facing away from each other. The bore in the base may be tapered or may have a smaller portion to prevent the sleeve from sliding completely through the bore. Opposing openings are located on either side of the base for engagement by an instrument, such as a hook holder, to aid in the placement of the hook assembly before inter-connection with the treaded rod. Preferably, the hook assembly forms a part of a Harrington compression rod or a tensioning means which interconnects a Harrington distraction rod and a Harrington compression rod.

ELECTRONIC CONTROLLER OF HYDRAULIC PRESSURE FOR JOURNAL LOADING OF BOWL MILL ABSTRACT OF THE DISCLOSURE An electronic system particularly suited for effecting control over the pressure of the hydraulic fluid through which the journal loading is established on the grinding rolls (20) of a bowl mill (10) of the type that is employed to pulverize coal. The subject electronic system is operatively connected in circuit relation to the belt feeder means (12), located externally of the bowl mill (10), that supplies to the bowl mill (10) the coal that is to be pulverized therein. In addition, the subject electronic system is also operatively connected in circuit relation to the hydraulic power unit (22) of the bowl mill (10) that provides hydraulic fluid under pressure to the grinding rolls (20). Accordingly, the subject electronic system is operative to monitor both the rate at which coal is fed to the bowl mill (10) and the pressure of the hydraulic fluid supplied to the grinding rolls (20) such that as the feed rate of the coal varies the hydraulic pressure being applied to the grinding rolls (20) can be made to vary so that the grinding forces that the grinding rolls (20) exert can be maintained substantially as an optimum regardless of the rate at which the coal is being fed to the bowl mill (10).

Dust disposal cyclones

en

ABSTRACT OF THE DISCLOSURE The efficiency of dust removal by cyclones may, even in case of cyclones of the recycling type, be improved by providing a gap between the clean air outlet of the cyclone and a flank of its dust laden air inlet which con-nects the dust collecting chamber of the cyclone with the ambient atmosphere. Due to the dust laden "primary" air introduced through the dust laden air inlet "secondary" air will be sucked in from the ambient atmosphere. Such secondary airflow will impel the primary airflow towards the periphery of the dust collecting chamber whereby dust particles carried by the primary air will be congregated in the vicinity of the inner wall surface of the cyclone as they enter its dust collecting chamber. Thereby, the collection efficiency of the cyclone will considerably be increased since dust particles already travelling in the peripheral portion of the airflow are more readily re-moved therefrom by centrifugal forces. The energy consump-tion increases only slightly. Further improvement of the collection efficiency can be obtained by providing a pass-age in the clean air outlet opening into the dust collecting chamber since then the air is recycled from the clean air outlet into the dust collecting chamber in the form of a tertiary air with the suction of the secondary airflow.

Methode et dispositif de nettoyage simultane des sieges d'un robinet a double siege

fr

ABSTRACT The invention relates to a new method and apparatus for the simultaneous cleaning of both seat-surfaces of a double-seat valve of which at least one side thereof is in contact with a liquid product which is flowing through the system in which the valve is located. Prior to this invention, it was not possible to clean the seat-surface of the closure-member which was in contact with the product at the same time as the other closure-member was being cleaned. The invention will be particularly useful in the food processing industry as the valve ensures that while the pipeline system on the one side of the valve is being cleaned, none of the cleaning agent reaches the pipeline system on the other side of the valve. The valve is equipped with two closure-members at least one of which is a slide and the other one of which is a slide or in the form of a seat-plate, said closure members being moved by an actuating means, either independently or together. When the cleaning of the piping system on one side of the valve is taking place, the invention ensures no cleaning agent enters the other side of the valve. By means of a partial stroke of one valve-stem and a stop determining the position of the other valve-stem, cleaning of the valve can be carried out when the monitor signals the valves are in a closed position.

Methode de mise sous pression et de consolidation de couches rocheuses par injections periodiques et repetitives d'un fluide de prise a coefficient de durcissement limite

fr

ABSTRACT A finite region of overpressure can be created in solid underground formations by the periodic injection of a fluid that has finite gel strength that subsequently, after each injection, partially sets - i.e., equivalently becomes a very much stronger gel. A region of overpressure is a region in which the static, locked in pressure is larger than what was there before. A region of overpressure can be used to prevent a roof of a tunnel from caving by adding compressive stresses in the roof. A sequence of regions of overpressure can be used to lift an arch or dome underground, squeeze off water or gas flows, stabilize dams, foundations, large underground rooms, etc. In general, the stress or pressure distribution in rock can be altered and engineered in a fashion that is more advantageous than what would have been the case without over-stressing.

ABSTRACT OF THE DISCLOSURE An automatically locking slider for slide fasteners has a locking member including a piece of resilient strip which is bent into a generally "3" shape having a U-shaped base extending around a transverse spindle of a pull tab, a locking prong extending from one end of the base, and an anchor extending from the other end of the base and terminating in a recessed end interlocked with a locking-member retaining nose on a slider's neck. The base is normally urged against the spindle of the pull tab by the resilience of the strip. The recessed end of the anchor is normally urged against the nose by the resilience of the strip and is thereby prevented from becoming out of interlocking engagement with the nose. Thus the locking member is held in position on a slider body solely by the resilience of the strip, requiring no bending or deformation of any part of the slider body that would make the slider defective from an aesthetic view.

AIR-SEALED OIL DEFLECTOR Abstract of the Disclosure An air-sealed oil deflector is disclosed which prevents leakage of oil from bearings or a rotating shaft and which prevents the ingestion of unfiltered atmospheric air which can lead to contaminant build-up and damage to the shaft. The air-sealed deflector includes an annular plenum surround-ing the shaft and an annular feed slot interposed between the shaft and the plenum to fluidly interconnect the plenum with the chamber between at least two seal rings immediately adjacen the shaft. The plenum is adapted to receive a continuous flow of forced air from an air supply system including an air prime mover and means for filtering air drawn from the atmosphere which serves as the ultimate air source. The plenum being relatively large in volume, and having a cross-sectional area large with respect to the air feed conduit to the plenum, provides a very uniform source for air flow radially inward, in a sheet-like fashion, toward the shaft through the feed slot. The air-seal is formed as the sheet-like flow of air is released between working clearances between the shaft and the seal rings. A perforated diffuser ring mounted in the feed slot contributes to the desired pressure distribution and eliminates detrimental viscous drag effects.

The thermal coefficient of expansion of the polyester tube is similar to that of steel. A gap or space is provided between the tube and the roller core, which gap is completely filled with adhesive. Because the jacket is seated on the rigid sleeve with prestressing as a result of thermal contraction subsequent to cooling, the cover can not separate from the roller core even under heavy loads. The cover can be mounted on the roller core by the user within a very short time. It is not necessary to ship the roller core to the resurfacing plant to renew the roller cover.

Methode et appareillage de clarification de l'eau

fr

Abstract of the Disclosure The invention is concerned with the clarifi-cation of waters that contain usable sludge, fibres or equivalent. The objective is to recover the usable material, e.g., as fuel, and at the same time to prevent pollution of waters. According to the invention, the separation of the solids, such as fibres and any other utilizable material, from the water takes place so that the water containing solid material is fed into or onto a mobile and utilizable layer of material placed on a perforated moving base, e.g. a wire-bottom conveyor (5), so that this material layer functions as a filter. The invention is in particular suitable for the wood processing industry, wherein the water coming from the barking drum (1) is passed into a clarifier tank (7), from which the water containing fibres is pumped onto a layer of bark material carried on a wire-bottom conveyor (5), whereby the bark layer filters the water passing through the bark layer. Likewise, water containing solids can be pumped from a waterway or clarifying basin into or onto a bark layer placed on a wire-bottom or equivalent con-veyor to be filtered there, whereat the solids in the water remain in the bark material and pass along with the bark material, e.g., into a dewatering drum, and the water filtered through the bark layer passes back into the waterway or clarifying tank. The filtered warm "circulating water" collected in the upper part of the clarifying tank (7) is pumped back into the barking drum (1).

Pressure Modulating and Reducing Valve Abstract A pressure modulating and reducing valve communicates pressurized hydraulic fluid from a pump to a hydraulically actuated clutch of a transmission at a modulated rate of pressure rise and at a reduced pressure. In order to provide a compact valve, the valve has a pressure reducing valve spool slidably nested within a sleeve member of a load piston to provide a valving action therebetween for controlling fluid flow between an inlet port, a load port and a drain port in a body. Movement of the sleeve member causes an increase in the pressure at the load port which causes the pressure reducing valve spool to move against a spring to establish a pressure in the load port proportional to the travel distance of the sleeve member. Movement of the sleeve member is controlled by a solenoid control valve having a spool slidably nested within a projection of an end wall extending into a bore of the pressure reducing valve spool.

Exploration sismique avec identification des zones a debit lent dans les gisements

fr

ABSTRACT This invention consists of producing a two-dimensional display from exploration seismic data designed to indicate zones of anomalous low velocity in the subsurface. Such zones may be indicative of porosity and the possible occurrence of hydrocarbons. They will be localized in terms of position along the seismic profile and in approximate zone of reflection arrival time. Data used in making the display are derived from both the CDP stacked seismic profile and corresponding velocity analyses used also to stack the data itself. Stacking velocity curves are plotted according to CDP location for each reflector designated by an interpreter to be of interest. These curves are overlain in pairs using calibration calculations and empirical criteria. Calibration helps smooth "noisy" values and compensates for velocity variations resulting from changes in separation or dip of the two reflectors from which the overlain velocity curves derive. In addition, it is presumed that the interval bracketed by each reflector pair taken in turn has uniform or only regional lateral variations of interval velocity - no local lateral variation is assumed. "Cross overs" or convergences of the paired curves thus indicate zones of either high or low interval velocity of local nature. The display itself consists of the velocity curves for all possible reflector pairs and vertical bands of color which are assigned to identify the reflection interval of particular low velocity zones which are shown consistently by all reflectors taken in pairs which bracket such zones. Horizontal position is of course indicated by the CDP location.
