Abstract: DYNAMIC RANDOM ACCESS MEMORY REFRESH CONTROL SYSTEM   Abstract of the Disclosure A system and method are disclosed for automatically refreshing a dynamic random access memory (DRAM) under a plurality of different opera-tional conditions of an associated processor.          In a preferred embodiment of the invention, when the processor is normally executing instructions it gene-rates active signals.  These active signals enable a generator circuit to generate timing signals.  A hidden refresh circuit uses status signals and a first part of these timing signals to generate a refresh pulse during an opcode fetch cycle of each instruction being executed by the processor.  A control circuit uses each refresh pulse and a second part of the timing signals to generate a row refresh signal to refresh a row in the DRAM indicated by a row address from a counter and a row address clock to increment the counter to the next row in the DRAM to be re-freshed by the following row refresh signal.  When a keep alive circuit senses that the processor has not run for a preselected period of time due to the in-circuit use of a piece of test equipment, the keep-alive circuit generates pulses to enable the hidden refresh circuit to cause the control circuit to peri-odically refresh the DRAM until after the processor starts running again.  When a halt/power-down circuit senses that the processor is executing a HALT instruc-tion, it forces the processor to branch off into a subroutine to execute a preselected number of instruc-tions to refresh an associated number of rows of memory in the DRAM before allowing the processor to return to its HALT instruction.  This operation peri-odically repeats until the processor has completed its HALT instruction.  When the halt/power-down circuit senses an impending power failure, it switches the system over to a back-up, power down mode of operation and also generates signals to enable the control circuit to continuously refresh the DRAM until after power is restored.

Abstract: PROCESS FOR PREPARING SILICON-BASE COMPLEX FERROUS ALLOYS                   Abstract The invention relates to a process for the continuous preparation of silicon-base complex ferrous alloys from cheap raw materials by preparing a charge with a high electric resistance and reducing the same in an electric arc furnace.  According to the invention, a charge is assembled which contains the total amount of carbon in a 0.82 to 0.99-fold quantity of that required to reduce all oxides of the charge to elements and adjusting this carbon content by preparing pellets which, in addition to the binding material, contain a)  as oxide to be reduced in an amount of at least 50% by weight such oxides of only base-forming or only amphoteric or only acid-forming elements which form with each other compounds or eutectics melting above 1600°C, and b) a carbonaceous reducing agent and/or carbides in such an amount that the quantity of carbon is either 1.05 to 1.35 times higher than required to transform the oxides of the pellet to the carbides or 0.66 to 0.02-fold of the quantity required to reduce the oxides of the pellet to metallic elements, and assembling the charge .alpha.)  from pellets con-taining an excess of carbon and/or from lumpy carbides and .beta.)  from carbon-deficient pellets or from a lumpy oxide of a base-forming or amphoteric or acid-forming element and .gamma.)  from lumpy carbon carriers, and optionally .delta.)  from an iron additive, with the pro-viso that no pellet may contain boron trioxide, and boron trioxide may not be present even as a charge component.  By the process of the invention, the utilization of cheap raw materials for the prep-aration of silicon-base complex ferrous alloys becomes possible without any deterioration of the quality of the alloy.

Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus and method for providing a universal electronic locking system (UELS) which controls an actuating device for a lock is disclosed. The system is composed of two elements, a signal-transmitting unit and a signal-receiving unit. The integrated circuit chip of the watch is expanded to include a programmable memory unit such that various codes may be entered in the watch and the codes may be changed at any interval desired by the operator. The signal-receiving unit comprises a photodetector for receiving an optical signal from the signal-transmitting unit and contains a programmable memory unit which is responsive to each and all codes contained in the signal-transmitting unit. Upon changing the code signal in the signal-transmitting unit, the memory unit of the signal-receiving unit may be reprogrammed so as to be responsive to the newly encoded signal and allow the latching mechanism of the lock system to be operated. The system may be used alone or in combination with conventional key operated locking mechanisms. The UELS is contemplated for applications in the home, business, industry, recreation, defense and wherever locks and codes are used.

Abstract: Abstract of the Disclosure A sling assembly for carrying shoulder-fired weapons, particularly military rifles, in an upright horizontal ready position.  A strap portion of the sling assembly extends rearwardly from a sling swivel on the bottom of the butt stock and then extends upwardly along the butt plate on the rear side of the butt stock, where it is retained detachably by a sleeve slidably disposed on the strap.  The sleeve includes a portion of a de-tachable connector to hold the sleeve and strap against the butt plate, the other mating portion of the fastener being located on the butt end of the stock.  The sleeve extends high enough relative to the butt stock so that raising the rifle to the user's shoulder separates the parts of the detachable connector, allowing the sleeve and strap portions of the sling assembly to fall clear of the butt end of the stock while the sling remains connected to the weapon by the sling swivel.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to the quantitative assay of low concentrations of biological mono-amines (amines being molecules having a primary or secondary amine function), in which the antibody-binding affinity of biological monoamines is increased on the order of 100,000-fold by a novel chemical conversion of the biological monoamine by means of a novel reagent.  The resulting compound, the modified monoamine, may then be incubated with (1) a chemical analogue of the modified monoamine which is marked, thus identifiable in some way, by possessing one of radioactive, fluorescent, or enzymatic activity, and (2) calibrated amounts of antibody produced to specifically bind the modified monoamine.  Following incubation, the concentration of the biological monoamine can be derived by determining through the radioactive, fluorescent, or enzymatic activity of isolated analogue-antibody complexes a measure of antibody bound to analogue, thus a measure of antibody bound by the modified monoamine, where the lower the analogue-specific activity, e.g. radioactivity observed in the isolated antibody complexes is, the greater is the modified monoamine, thus the greater the biological monoamine concentration.

Abstract: ABSTRACT     Electrical continuity between an electrical terminal and a metal core of an insulated electrical lead is tested for, by simul-taneously supplying substantially identical oscillatory signals to the terminal and to the arms of a two-arm bridge circuit, the arms of which are connected to respective inlets of a differential amplifier and are grounded through capacitances and a ground plane existing in the vicinity of the lead. If there is electrical continuity between the terminal and said core, the capacitance between the core and the ground plane causes imbalance between the signal inputs that are applied by the bridge circuit to the differential amplifier to cause it to emit a continuity success signal.
