Abstract: ABSTRACT OF THE DISCLOSURE         An ambient temperature electric cell of primary and secondary nature, characterized by the use of a dithionite radical of an alkaline metal as the charge transfer agent, and including processes for manufacturing and for operating the same.  The dithionite is dissolved in an anhydrous electrolyte comprised of a suitable solvent, which may also contain a salt of the same alkaline metal and be saturated with sulfur dioxide.          A sealed and evacuated cell (negative electrode, inert highly porous space, and positive current gathering electrode) is filled with the electrolyte and subjected to a charging current sufficient to plate the alkaline metal onto the negative electrode while further saturating the electrolyte with sulfur dioxide.  In the case of a secondary cell, the electrolyte is capable of redissolving the dithionite produced upon discharge, such procedure being enhanced by a system for forced circulation of the electrolyte.  In the case of a primary cell, redissolution is not necessary and the final cell potential and discharge character-istics can be enhanced by replacing the dithionite electrolyte with other anhydrous electrolyte solutions (e.g., sulfuryl chloride or thionyl chloride). The cell is characterized by extremely low internal resistance, long shelf life, excellent performance over a wide temperature range, and negligible depletion of the active dithionite charge transfer agent.  In a particular high energy battery system, an electrolyte containing dissolved dithionite is circulated between a battery chamber and an auxiliary chamber containing solid dithionite salt (e.g., lithium dithionite).  The electrolyte circulates from the auxiliary chamber through a solids separating means (centrifugal separator) to the battery chamber, where the electrolyte containing freshly dissolved dithionite is passed through a highly porous intermediate passage between an elongate active anode (e.g., copper) and an adjacent elongate current gathering cathode (e.g., finely divided carbon), in such fashion as to minimize internal resistance to current flow while substantially increasing the energy storage capacity of the battery cell.

Abstract: ABSTRACT           This specification discloses a pair of matable electrical connectors.  The locking structure includes a ramp member formed on one of the connectors and a pair of cantilevered beams formed on the other connector.  The cantilever beams have an enlarged portion which coacts with a flat locking surface on the ramp member.  The ramp member also includes a prow like wedge which is adjacent the flat locking surface.  Deflection of the cantilevered beam enlarged portion from the locking surface to the wedge aligns the enlarged portion so that it can be withdrawn from the ramp member while the wedge spreads the canti-levered beams apart.  During mating of the connectors, the cantilevered beams ride up and down on the ramp member until they reach the flat locking surface.  During unmating of the connectors, the cantilevered beams are squeezed down and then pulled so that the wedge spreads the beams.  Unless the beams are deflected to clear the flat locking surface, the enlarged portions of the beams engage the locking surface to resist unmating of the electrical connectors.

Abstract: ABSTRACT:   An amplifier circuit  arrangement suitable for use in phase lock loops incorporated in radio receivers, particularly portable receivers. The amplifier circuit arrangement comprises an inverting and a non-inverting amplifier connected between a common input and respective inputs of a summing circuit. The gains of the amplifiers are unequal for low amplitude input signals but are arranged to produce substantially equal antiphase limited outputs for high amplitude input signals. By making the gains of the amplifiers greater than the difference between their gains a rapid transition is obtained form a situa-tion where the gain corresponds to the numerical differ-ence between the amplifier gains to one where it has fallen to a low level.  This property can be used in a phase lock loop of which four examples are given; when the beat frequency output of a phase sensitive detector con-nected to the input of the amplifier arrangement is large, the output of the summing circuit will be low. Conversely, when the phase sensitive detector falls to a low level indicating that a frequency lock is obtained the output of the summing circuit will be high.

Abstract: ABSTRACT OF THE DISCLOSURE         A virtual storage data processing system having an address translation unit shared by a plurality of processors, located in a memory control unit connected to a main memory is disclosed. One of the plurality of processors is a job processor which accesses the main memory with a virtual address to execute an instruction and includes a cache memory which is accessed with a virtual address.  One of the plurality of processors is a file processor which accesses the main memory with a virtual address to transfer data between the main memory and an external memory.  The cache memory receives the virtual address when the file processor writes to the main memory and if it contains a data block correspond-ing to the virtual address, it invalidates the corres-ponding data block.  The address translation unit trans-lates the address differently for the access from the file processor and the accesses from other processors.

Abstract: ABSTRACT In a magazine for plug-in electrical assemblies, guide bars (4) for the assemblies (1) are supported in openings (8) of horizontally arranged U-shaped carriers (5).  The openings (8) are arranged in a continuous row and aligned in pairs in the side walls of the carrier (5). At its end, the carrier (5) is cut off approximately along the centre line of a pair of recesses so as to form projections (13) which project into corresponding openings (10) in a side plate (7) of the magazine.  By means of resilient engaging hooks, the guide bars (4) engage into the openings (8) of the carriers (5).  Between the assem-blies (1) there are arranged individual support plates (18) which engage by means of upper and lower projections (19, 20) into the openings (8) of upper and lower carriers and are secured therein by means of lateral support lugs (21) and additional locking elements (e.g. 23).  It was hitherto common to design the openings which accommodate the guide bars as saw-tooth notches in the longitudinal edges.  Since these openings are not suitable for accommodat-ing plug-in nuts and for forming lateral projections, the projections and open-ings for the plug-in nuts had to be produced by a separate punching step.
