Abstract: ABSTRACT OF THE DISCLOSURE         A switching device comprises two identical active switching components connected in series and each comprising an operational amplifier with keying elements in a negative feed-back circuit and two identical operational amplifier null bias vol-tage memory circuits.  The input of each of said null bias vol-tage memory circuits is connected to the output of a respective one of the operational amplifiers.  The output of each memory circuit is connected to the non-inverting input of the respec-tive other operational amplifier so that the output of the first memory circuit is connected to the non-inverting input of the operational amplifier whose output is connected to the input of the second memory circuit.  The output of the second memory circuit is in turn connected to the non-inverting input of the operational amplifier whose output is connected to the input of the first memory circuit.  This arrangement reduces possible errors in the device when commutating a DC signal.

Abstract: 17.2.1979                 1                    PHD 78-036 ABSTRACT: "Method of and apparatus for generating improved recon-struction images in computerized tomography equipment."             The method relates to an X-ray apparatus, which by the rotary scanning with the aid of a fan-shaped radiation beam provides measuring data about the radiation attenuation in the layer of a body, from which subsequent-ly the absorption distribution of the layer being examined is calculated. In such an apparatus it is important that the centre of rotation is accurately known. If this centre is not exactly known, this leads to blurring in the re-constructed image. If scanning is not performed over a full revolution, this moreover gives rise to streaking artefacts. The method proposed automatically yields the centre of rotation from the measuring data, so that during the subsequent reconstruction allowance can be made for the centre of rotation.

Abstract: ELECTRIC FUSE HAVING FOLDED FUSIBLE ELEMENT AND  HEAT DAMS                        Abstract of Disclosure A fusible element for electric fuses combining the ability of interrupting with a time-lag currents in the overload range with the ability of interrupting with a current-limiting action currents in the range of short-circuit currents.  The fusible element comprises a relatively wide perforated center section and axially outer heat-dam-strip sections of relatively uniform cross-section.  The center section has points of reduced cross-section imparting to it a predetermined fusing i2.t.  The center section of the fusible element is folded in a direction longitudinally thereof to effect mutual heating of the portion, or portions, thereof to different sides of the fold, or folds. This allows to increase the mass of the center section and results in an in-crease of time-lag.  The relatively wide center section is further provided with an overlay of a metal having a fusing point lower than the fusing point of the metal of which the center section consists to sever the center section on occurrence of currents in the overload range.  Relatively narrow heat-dam-strip sections extend from the ends of the center section to the termi-nals of the fuse.  The fusing i2.t of the heat-dam-strip sections is larger than that of the center section to avoid fusion of the heat-dam-strip sections prior to that of the center section, or to entirely preclude fusion of said heat-dam-strip sections.  The heat-dam-strip sections are folded in transverse direction preferably a number of times which increases their length for given casing dimensions, and consequently their resistance to axially outward heat flow from the center section, thereby en-hancing the same effect that results from the reduced width of the heat-dam-strip sections relative to the width of the center section.      The points of reduced cross-section of the center section are of a metal having a relatively low fusing i2.t, in particular silver, to minimize its fusing i2.t.  The heat-dam-strip sections are of a metal other than silver in the interest of greater economy and greater flexibility.  Electroconductive bonds con-nect the center section to the heat-dam-strip sections.

Abstract: DMD:L 6-2?-78 TIMER            Abstract of the Disclosure The timer controls a dispensing machine and in particu-lar controls the dispensing cycle for a product such as in-stant potatoes by temporally regulating the water portion of the cycle in conjunction with the solid or powder (potato granules or pearls) portion of the cycle.  The water flow is usually controlled using a solenoid or the like while the quantity of potato is regulated by an auger and associated drive motor.  The dispensing cycle is initiated by a pre-rinse period wherein only water flows.  During the main part of the cycle both water and product flow into a mixing area. The cycle ends with a post rinse period that is either posi-tive or negative; positive when the product flow stops first and negative when the water flow stops first.  For multiple portions, rather than extending the length of the main part of the cycle, the timer includes means for repeating the basic cycle a number of times that relates to the desired portion.  All periods comprising the overall basic cycle are preferably adjustable in duration.
