Abstract: ABSTRACT OF THE DISCLOSURE     For the electropneumatic inspection of the longitudinal and/or transversal permeability of the ventilated cigarettes, each cigarette is subjected in any order of succession to at least three of the four inspections consisting in applying a pneumatic pressure alternatively to each of the two cigarette ends, while keeping the opposite end open and subsequently closed. Each of these inspections determines the pneumatic resistance met at the respective cigarette inlet and the values of these resistances are converted into electric signals and used for determining the longitudinal and/or transversal permeability of the cigarette. For this purpose use is made of the theory of the electric quadrupoles, by considering that the cigarette pneumatic resistance can be rewarded as composed of an equivalent transversal resistance, derived between two equivalent longitudinal resistances in series between each other.

Abstract: TITLE        ACTIVE QUADRATURE CURRENT REFERENCE SOURCE     INVENTORS                   William J.M. Moore Norbert L. Kusters Eddy So ABSTRACT OF THE DISCLOSURE              This reference source provides a current which is of relatively high magnitude and which leads the voltage by substantially 90°.  It includes a reference capacitor which is highly stable and pure but of low capacitance, and a power capacitor which has a high capaci-tance.  The capacitors are connected together at one end for coupling to a voltage source.  A current comparator compares the currents flowing through the reference capacitor and the power capacitor, and provides a difference signal.  A circuit generates a current in response to the difference signal and adds the generated current to the current through the power capacitor resulting in a current having a waveform and phase substantially identical to the reference capacitor current which leads the voltage source voltage by substantially 90°.

Abstract: INVENTORS: JEAN-MICHEL SHCAULIN, ROBERT GANTIN and Y?SAR KANAT            INVENTION: MARINE FIRING WEAPON FOR FIGHTING AIRBORNE TARGETS, ESPECIALLY IN ZENITH     ABSTRACT OF THE DISCLOSURE     A marine firing or weapon system is disclosed for fighting rapidly moving targets in zenith and possesses an azimuth or lateral alignment axis which is inclined through about 35°.  The ammunition infeed is accomplished from four stationary drum magazines rotatable about vertical axes.  The drum magazines are located below the weapon.  Since the belted ammunition, owing to the inclined azimuth alignment or aiming axis is infed along a bent, central, column which is vertical or upright at its lower region, there is required lengthwise compensation of the belted ammunition during azimuth alignment or aiming of the weapon.  The weapon barrels are cooled.  Because of the inclined azimuth alignment axis the minimum elevation is limited by an adjustable stop or impact member.  The drum magazines possess compartments each of which contain a respective loop of the cartridge belt.

Abstract: ABSTRACT: Data input or output apparatus incorporating functional testing.         For functional testing, all electromechanical elements of a data input or output apparatus are indivi-dually and successively activated. The current supplied by a power supply is measured at least as one instant and the measurement value is compared with a reference value. Thus, the power supply lead need include only a (possibly switchable) measuring element and a customary A/D conver-ter and possibly a measuring range controller, the further functional testing being realized by means of the digital units already present. Due to the small number of elements on the one hand, the reliability of the apparatus is not affected to any significant degree, while on the other hand the functional testing is thus realized in a very inexpensive manner.

Abstract: WASTE PAPER DISINTEGRATING, SORTING AND FIBER RECOVERY APPARATUS            ABSTRACT OF THE DISCLOSURE        The disclosure concerns apparatus for disintegrating waste paper and for sorting out fibers to be recovered from the suspension.  There is a disintegrating chamber connected by a gravity feed discharge line to a drum type or vibration sorting device.  A circulating member disposed in the disin-tegrating chamber rotates about an axis that is tilted at a small acute angle from the vertical.  A screen located be-neath the circulating member separates the disintegrating chamber from a discharge chamber beneath the screen.  The screen sorts out coarser particles letting only finer sus-pension particles pass into the discharge chamber.  A first suspension discharge line communicates with the discharge chamber while a second suspension discharge line communicates with the disintegrating chamber immediately above the screen. Both discharge lines empty into each other and lead to -the sorting device.  Appropriate slides control flow through the two discharge lines.  The preferred sorting device is a horizontally oriented, rotatable, perforated drum and the suspension delivered into the drum is screened, with the good suspension being collected and the coarse material being trapped inside the drum to exit from an end.

Abstract: ABSTRACT      Vitamin B12 (cobalamin) and/or folate (folic acid) assay tech-niques can be simplified, by eliminating the step of heating or boil-ing the to-be-tested sample prior to its assay.  This is accomplished by utilizing compositions and procedures: (1)  which substantially completely liberate all vitamin B12 and/or folate from endogenous binding protein without heating or boiling; (2)  which substantially completely destroy all endogenous bind-ing protein which is present in the to-be-assayed sample, and which may bind natural and radioactive vitamin B12 or folate both due to its liberation from vitamin Bl2 or folate in the original sample or due to its unbound presence in the original sample; (3)  which substantially completely inhibit or block any unde-stroyed endogenous binding protein; and (4)  which substantially completely inhibit or destroy any in-trinsic factor-blocking antibodies which may be present in the to-be-assayed sample. In preferred embodiments the protein destroying compositions utilized include both a strong base and a sulfhydral compound which is a strong disulfide protein destroying material while the material of choice to bind with undestroyed endogenous binding protein is a vitamin B12 analogue. The sample is then assayed using known, for example, radioisotope dilution assay techniques.
