Abstract: MAXIMUM POWER CONTROL FOR A SOLAR ARRAY           CONNECTED TO A LOAD              ABSTRACT OF THE DISCLOSURE    An analog and a digital control is provided which causes an ac to dc inverter operated in the constant power mode to supply sinusoidal current to a utility while drawing maximum power from a solar array. The current drawn from the array is forced to be proportional to the array voltage by a variable gain amplifier so that the inverter presents a resistive load to the array which remains statically stable under rapid changes of insolation while using a perturb-and-observe method of maximum power tracking.  The perturb-and-observe method adjusts the gain of the variable gain amplifier to achieve maximum power output from the solar array.

Abstract: SELECTED WELL COMPLETION FOR IMPROVING VERTICAL CONFORMANCE OF STEAM DRIVE PROCESS            ABSTRACT          The method combines the driving of oil by steam from an injection well to a production well with the overriding tendencies of the steam to give both good temperature conformance and good vertical sweep by completing the injection and production wells in limited intervals in the oil-containing formation.  The injection well is completed in the bottom 20-30 percent of the vertical thickness of the oil-containing formation and the production well is completed in the bottom 40 percent of the vertical thickness of the oil-containing formation.  Once the wells are completed over the limited intervals, steam is injected into the oil-containing formation at a rapid rate and fluids including oil are recovered from the formation via the production well.  Injection of steam is continued until the fluid being recovered contains an unfavorable amount of steam or water.  If the oil-containing formation overlies a water-saturated formation, optimum vertical conformance is obtained with the completion interval of the injection well in the bottom 20-30 percent of the vertical thickness of the oil-containing formation and the production well completed over 30-40 percent of the vertical thickness of the oil-cantaining formation beginning at a point above the water-saturated formation a distance of about 10 percent of the vertical thickness of the oil-containing formation.

Abstract: ABSTRACT OF DISCLOSURE       The combustion of fuel gas to achieve improved thermal efficiency and to suppress NOx formation is con-ducted by adding preheat to the combustion reactants followed by flameless combustion on the outer surface of a porous fiber burner.  Preferably, all of the desired combustion air is pre-heated by indirect heat exchange with the flue gas resulting from the flameless combustion and the preheated air is then admixed with the fuel gas fed to the porous fiber burner.         Waste heat from available independent sources may also be utilized to preheat the combustion reactants.

Abstract: ABSTRACT OF THE DISCLOSURE     In optical data transmission systems it is desirable to interconnect various stations so that data arising at any one of the stations is trans-mitted to all of the stations.  With this arrangement it is necessary to include a system for determining whether a station is receiving, at any parti-cular time, data from only one other station or whether it is receiving superimposed data from two or more stations.  This latter condition known as collision is detected in a special optical receiver of the invention.  An optical receiver embodying the present invention is of the type which receives optical pulse signals from two or more optical transmitters.  Each pulse signal has been modulated in intensity with respect to two logical levels.  The optical receiver includes a photodetector.  A differentiator differentiates a received signal detected by the photodetector and has a time constant smaller than the pulse width of the received signal.  A decision circuit decides the polarity of an output pulse signal of the differentiator.  A circuit is provided for detecting the occurrence of two or more consecutive same polarity pulses in the output signal of the decision circuit.

Abstract: ABSTRACT IMPROVEMENTS IN OR RELATING TO SAMPLE-AND-HOLD           CIRCUITS AND METHODS.   A feedback sample and hold circuit has an amplifier whose output is connected through a sampling switch (SS) to the input of a buffer (B).  A holding capacitor (CH) is connected between input of the buffer (B) and ground potential.  A correction coupling  capacitor (CCC) and a correction holding capacitor (CCH) are connected between the input of the buffer (B) and ground,  A correction switch SC is connected between the amplifier output (14 and the common node (22) of the correction capacitors (CCC, CCH). When the sampling switch (SS) opens for the hold condition, the correction switch (SC) briefly remains closed to permit the amplifier (A) to correct the hold voltage for switching charge feedthrough error from the sampling switch (SS) by charging the correction holding capacitor (CCH).  The correction coupling capacitor (CCC) couples this correction in attenuated form to the holding capacitor (CH).

Abstract: ABSTRACT A container having a threaded neck is provided with a removal resistant cap which can be applied to the container neck by rotational thrust. The cap has a depending skirt having an internally threaded lower section with the threads terminating in a bead intermediate the ends of the skirt.  The neck has an upper threaded section with the threads terminating in a bead spaced below the top of the neck.  When the threads of the cap are engaged with the threads of the neck and the cap is rotated relative to the neck, the skirt will circumferentially expand so that the skirt bead passes over the neck bead.  At that point, the threads will no longer engage and the interlocked beads will inhibit removal of the cap. Means are provided to enhance removability of the cap from the neck by tearing away a portion of the skirt.

Abstract: ABSTRACT OF THE DISCLOSURE         An angled bolt is used for securing a mitered connection between two plates particularly furniture boards.  To obtain a satisfactory fit between the miters, the position of the bolt shanks in the plates must be well fixed.  This is obtained by a stop provided on the bolt so as to extend substantially in the plane of the joint.  The stop may take the shape of a ring or a star.  To be able to assemble plates also in other than right-angle positions, the connecting corner link is designed as a hinge, with the hinge pin extending perpendicularly to the bolt shanks and having flattened protruding ends which form the stops.          These stops come automatically into their position in the plane of the joint.

Abstract: ABSTRACT OF THE DISCLOSURE In an axial flow fan impeller with a number of blades rotatably journalled in a wheel rim, each blade root is connected with a blade shaft by bayonet engagement between these two elements, one of which has a part forming a bayonet plug member with at least one pair of opposed cam portions, whereas the other has a part forming a bayonet socket member with a bore with recesses matching said cam portions.  The bayonet plug and socket members may individually be formed as parts of either the blade root or the blade shaft.  In the axial direction, the recesses in the bore of the bayonet socket member is designed with an axial play relative to the axial length of the cam portions of the bayonet plug member.  Two fixation screws extend through threaded bores in the blade root and have their ends formed as smooth guide portions for insertion into fit bores in a centering portion of the blade shaft. Inside the guide portion, each fixation screw has a shoulder portion for abutment against a spring member arranged between the blade root and the side of the centering portion facing the blade root.  At the mount-ing of the blade, the fixation screws are tightened after completion of the bayonet engagement.  Thereby, the blade root with the blade will be pressed outwardly due to the pressure from the spring member for frictional engagement between the cam portions of the bayonet plug member and the recesses in the bore of the bayonet socket member.

The nosepiece is attachable to a driving tool and has rigid prongs which reach through open-ings in the lath.  Travel of a bit on the driving tool is limited so that automatic disengagement occurs to prevent over-driving of the screw.
