Abstract: ELECTROCHEMICAL CELL SIMULATING         CIRCUIT ARRANGEMENT                             Abstract An  electronic  circuit  arrangement effecting current flow simulating the faradaic current, oxidation reduction potential and the like of an electrochemical cell encompasses two key concepts. The first recognizes that since the semi-integral of the cell current effectively deconvolves the diffusion aspect of the phenomenon with the resultant describing the surface concentration  of   reacted   species,   then  the semiderivative of a function describing a surface con-centration of reacted species results in an output representing the cell current, including diffusion.  The second is embodied in a circuit arrangement properly simulating this concentration behavior cell double layer potential and in yielding an output proportional to the surface concentration of reactant species corresponding to that potential in response to applied cell barrier potential.

Abstract: ABSTRACT OF THE DISCLOSURE:         Spot- and projection-welding of aluminum sheets has always been connected with difficulties, mainly because of the surface layers of aluminum oxide, and even by pickling, these difficulties could be only partly eliminated.  The main diffi-culties have always been unsufficient electrode life times, the unsatisfactory quality of the weld and especially the unsolved problem of achieving good quality welding and long electrode-life when using un-pretreated aluminum sheets.  The problem has been solved in principle by using electrodes having pro-filed contact-surfaces, by means of which the layer of oxide is broken during pre-pressing and a direct contact between the electrode and unoxidized material of the workpiece is provided, the contact-resistance of which is lower than the portion of the overall resistance of the point of weld formed by the metal of the aluminum sheets to be welded together.  In an appro-priate welding machine, the means for switching-on the welding current are controlled in such a manner that the welding cur-rent is switched on only after a sufficiently large contact area and therewith a sufficiently low contact-resistance of this contact has been reached.

Abstract: ABSTRACT OF THE DISCLOSURE            A safety closure, preferably for a medicine bottle, has a screw cap or other closure cap which is to be rotated to be applied or removed, and a blocking mechanism in the form of an elastically resilient blocking member on the bottle neck or a collar securely mounted on the neck, and a stop face on the closure cap.  The cap has an area of reduced wall thickness which is opposite the blocking member in the closed position and permits the blocking member to be actuated by external pressure on the cap.  When the cap is rotated in the direction of removal from the closed position, the stop face encounters the blocking member and prevents additional rotation, unless the blocking member is pressed clear of the stop face by pressure on the closure cap.  The blocking member is elongate and merges at both ends into the bottle neck or collar, but is spaced from the neck or collar at its central portion, which has a blocking face.  This allows the blocking member to retain its tendency to return to the blocking position after actuation, even though the elasticity of the material decreases after many operations.

Abstract: A B S T R A C T   MOLDED CASE CIRCUIT BREAKER APPARATUS WAVING  TRIP BAR WITH FLEXIBLE ARMATURE INTERCONNECTION           The  invention  relates  to  a  circuit  breaker including a trip bar assembly (60) which is movable to a circuit-breaker tripping position by a bimetallic element (38) deflecting in response to an overload current, and by a magnetic armature (66) magnetically attracted (yoke 100) in response to a fault or short-circuit current.         The armature (66) is connected to the trip bar assembly (60) in such a manner (flexible attachment member 68, and rigid, preferably metallic, backing member 67) as to cause the trip bar assembly to move positively as one with the armature during movement thereof due to magnetic attraction, and to enable the trip bar assembly (by virtue of the flexible armature attachment 68) to be moved beyond its normal tripping position when the armature is in its fully attracted position.         Enabling the trip bar assembly to move beyond its tripping position enables it to yield to the bimetallic element  (38)  in the event of a wide deflection thereof resulting from high thermal loading.  Thus, the bimetallic element can deflect essentially unrestrainedly and, hence, without risk of taking a set and falling out of caliber-lion.  Accommodating wide bimetallic deflections in this manner permits the use of small-gap magnetic trip means for fast response.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is circuitry which is employed with a data terminal, which data terminal in turn is part of a system including a main computer.  The present circuitry includes a microprocessor which is connected to the main computer and to the keyboard. The microprocessor processes signals from both the main computer and the keyboard.  The system has a plurality of operational function circuits, such as a circuit to effect smooth scrolling on a data display.  Logic circuitry is connected between the microprocessor and the operational function circuits.  The logic circuitry provides a first path which permits signals, generated in response to instructions from the main computer, to pass therethrough to select one of the operational function circuits and simultaneously therewith to turn the selected circuit either "on" or "off".  The logic circuitry also provides a second path which permits signals, generated in response to instructions from the keyboard, to pass therethrough to select one of the operational function circuits and turn that circuit either "on" or "off".  A circuit to generate an impeding signal is also included and is activated by signals from the microprocessor in response to signals from the keyboard.  This last-mentioned generator circuit is connected to impede signals which would otherwise be transmitted along the first path, whereby the keyboard, after selecting a particular operational function circuit, can "lock in" that circuit so that the main computer cannot turn that selected circuit "off".
