Abstract: CHARGE COUPLED DEVICE MEMORY     ABSTRACT OF THE DISCLOSURE Semiconductor memory cells include gate conductor-insulator-semiconductor regions having storage and transfer portions in which the threshold voltage and surface potential-gate conductor voltage characteris-tics differ as between the storage and transfer portions. This may be achieved by employing relatively thick and relatively thin insulator areas at the storage and transfer portions, or vice versa, with a surface charge accumulation layer at the semiconductor region insulator interface. In a different form of cell structure, the insulator is a uniform thickness layer overlying the storage and transfer portions one of which includes a doped semiconductor region of the same conductivity type as, but higher dopant concentration than, the remainder of the semiconductor region. The dif-ference in threshold voltage and surface potential characteristics is such that in response to first and second defined gate voltage levels, the potential well profile at the storage and transfer portions is changed in a manner permitting write in and read out of logic signal level related charge packets into and from the storage portion. Semiconductor memories include a matrix array of such cell structures, the gate conductor of a line of cells in the matrix forming part of a store/word conductor common to that line and a sense portion of each cell may form part of a common sense line for a line of cells extending perpendicularly to the store/word conductors. The memory cells may be fabricated by a process utilizing photolithographic alignment offset and self-aligning techniques in conjunction with diffusion and ion implantation techniques.

Abstract: Abstract of the Disclosure A method for the calibration or checking of dynamo-meters consisting in that a force is applied to the dynamometer subjected to calibration or checking through a master dynamo-meter.  The force applied is progressively changed in magnitude, and after each such application the force applied to the dynamometer subjected to calibration or checking is retained, simultaneously relieving the master dynamometer of the force.          In said method, a force is also applied directly to the dynamo-meter subjected to calibration or checking by means of standard weights.  An apparatus for the calibration or checking of dynamometers incorporating two frames whereof one is rigidly attached and the other is movable relatively to the first one.          Interposed between the frames is the dynamometer subjected to calibration or checking and interacting therewith is a means of applying a force which applies a calibrated force through the master dynamometer.  The apparatus incorporates one more means of applying a force installed with provision for apply-ing the force only to the dynamometer subjected to calibration or checking which also assures that the master dynamometer is relieved of the force applied.  me method and apparatus offer the prospect of checking and calibrating dynamometers against forces in excess of 10,000 kN with practically no upper limit and an error never higher than anywhere between 0.25 and 0.5%.

Abstract: ABSTRACT OF THE DISCLOSURE         An adsorbate is removed from a polymeric adsorbent by contacting the adsorbent with a supercritical fluid which is a sol-vent for the adsorbate.  The supercritical fluid containing the dis-solved adsorbate is then subjected to a physical treatment which renders the supercritical fluid a nonsolvent for the adsorbate and makes it possible to remove the adsorbate from the supercritical fluid.  The supercritical fluid is then subjected to another physical treatment to restore it to a state wherein it is a solvent for the adsorbate so that it may be reused.  The process is particularly suitable for adsorbent regeneration in the treatment of wastewaters.

Abstract: CONTROL ROD EJECTION RETARDATION ASSEMBLY                     ABSTRACT OF THE DISCLOSURE      A control rod ejection retardation assembly is mounted to a control rod assembly of a nuclear reactor to retard the ejection of the control rod only during an undesired ejection of the con-trol rod while allowing normal control rod movement and "scram-ming" operation to be drag free and unretarded.  The ejection retardation assembly includes a piston assembly mounted to the control rod and having an opening thereto controlled by a ball valve.  The piston assembly seals are made loose fitting to allow sufficient fluid flow through the seals to provide unhindered normal control rod movement even with the ball valve sealing the piston assembly opening.  During undesired speedy ejection of the control rod, the ball valve seals the opening to prevent fluid flow to the piston assembly retarding piston movement and thereby controlling control rod movement.  During a "scram" con-dition the ball valve unseals the piston opening allowing fluid to easily flow into the piston assembly to prevent any retarda-tion of piston and control rod movement.

Abstract: "Abstract of the Disclosure"           A process for recovering petroleum from subterranean reservoirs where high salt content water is used in a secondary recovery process consisting of forming as the displacement fluid a dilute alkaline silicate solution utilizing the high salt content water and filtering the alkaline flooding solution to remove scale-forming alkali insoluble salts which include a substantial proportion of calcium and magnesium salts.  The filtered solution is injected into the reservoir and this is fol-lowed by an injection of a slug of substantially neutral water.          A dilute acid solution is utilized to contact and dissolve the alkaline insoluble salts which have been filtered from the alkaline solution and the thus formed solution which includes a substantial portion of soluble calcium and magnesium salts is injected into the reservoir for subsequent contact with the alkaline silicate solution.  This contact results in the for-mation of precipitates which partially plug that portion of the reservoir in which the contact occurs and reduces the perme-ability thereof.  The process is repeated a plurality of times until the desired amount of alkaline silicate solution has been injected into the reservoir whereupon untreated water can be injected as a drive-fluid.
