Abstract: Abstract A heat exchanger element comprises a number of parallel tubes stacked on top of each other.  The tubes have a small hydraulic diameter and consist of initially circular tubes which have been compressed to assume a generally rectangular cross-section with fixed height and width. In certain sections along the tubes the compression has been made s-lightly less whereby the height is greater in these sections than in other portions of the tubes.  These sections having a greater height constitute spacer means between the stacked tubes.  The tubes are connected at both ends to manifolds having connections for the refrigerant.  The tube pack is disposed in an outer casing having connections for the heating medium.  The latter medium is thus adapted to pass between the compressed tubes, said medium being the cooling medium when the element constitutes part of an evaporator and heating medium when the element is part of a condenser.  The flow passages of the heating medium are generally rectangular and have a small hydraulic diameter, too.

Abstract: Méthode et appareil pour la détection et la localisation de défauts électriques et/ou décharges partielles dans un équipement électrique à isolation gazeuse, comme, par exemple, un câble, un poste blindé ou un disjoncteur à isolation gazeuse. L'appareil comprend une pluralité de capteurs de courant disposés à intervalle donné à l'intérieur du boîtier ou de la gaine de l'équipement pour détecter toute variation du courant circulant dans l'élément conducteur disposé à l'intérieur du boîtier. Chaque capteur est constitué par une bobine toroïdale qui peut être, de préférence, une bobine de Rogowski de type différentiateur. Cette bobine est placée dans une cavité annulaire usinée dans la paroi du boîtier de l'équipement tout autour de l'élément conducteur. Chaque cavité est reliée sur toute sa longueur à la surface intérieure de la paroi du boîtier par une fente dont les côtés opposés sont suffisamment éloignés pour être isolés l'un de l'autre. Chaque capteur donne un signal qui est proportionnel à la variation de courant détecté. Un circuit de contrôle est relié à chacun des capteurs pour comparer leur signal et mesurer l'intervalle de temps entre les moments où sont reçus les signaux fournis par les divers capteurs d'une même variation donnée de courant, et pour ainsi déterminer où est située le défaut ou la décharge partielle ayant causé cette variation donnée de courant. Les principaux avantages de cet appareil sont le fait qu'il n'est pas relié électriquement au circuit de transport du courant principal et le fait qu'il n'est pas influencé par la chute de potentiel associé la circulation du courant sur la surface intérieure de la cavité annulaire. De plus, la sensibilité de l'appareil peut être très élevée, puisqu'elle est proportionnelle au nombre de spires de la bobine toroïdale.

Abstract: ABSTRACT               "DYNAMIC TWO-PHASE CIRCUIT ARRANGEMENT"      As shown in Figure 6, a dynamic two-phase circuit arrangement comprises two flip-flops (601 and 602) each of which has an input stage (transistors 605/606 and 613/614), a non-inverting output stage (transistors 608/609 and 616/617) and an inverting output stage (transistors 610/611 and 618/619).  Two-phase control of the two flip-flops (601 and 602) is effected by drive pulses K1 and K2.          The arrangement also includes combinatorial logic (603) which is operated by the drive pulses K1 and K2 to feed counter clock pulses CP to the first flip-flop (601).  The flip-flop (601) performs a divide-by-two operation in response to the clock pulses CP and drives the flip-flop (602) from its Q-output.  The flip-flop (602) includes an additional switching transistor (620) which is also driven from the Q-output of the flip-flop (601).  This transistor (620) is connected to perform an OR-function with the non-inverting output stage (transistors 616/617) of the flip-flop (602).  As a result, this output stage produces shift pulses S having half the repetition frequency of the clock pulses CP.  The duration of these shift pulses corresponds to the period of the two-phase control cycle (K1, K2) of the arrangement.

Abstract: VACUUM AND GAS EXPANSION OF TOBACCO                    ABSTRACT OF THE DISCLOSURE          Tobacco is expanded by cooling the same to a temperature of about 30°F or less and subjecting such cooled tobacco to a subatmospheric pressure in a vessel.  CO2 gas is then introduced into the vessel and contacts the cooled tobacco to impregnate the tobacco with CO2 gas as pressure in the vessel is brought to substantially atmospheric pressure.          Subsequently, the cooled CO2 impregnated tobacco is subjected to conditions whereby the CO2 in the tobacco is removed and the tobacco is expanded.  Typically, the CO2 impregnated tobacco is introduced into an expansion tower wherein it is heated to increase the volume of the CO2 and to expand the tobacco in size.     BACKGROUND OF THE INVENTION        The present invention relates to methods for expanding tobacco and more particularly to methods wherein a gaseous agent is utilized to impregnate the tobacco under relatively low pressure conditions prior to expansion.        In the course of cutting, curing and otherwise preparing tobacco for use in the manufacture of smoking products such as cigarettes, the density of tobacco is increased relative to the density of tobacco in a natural condition.  Thus, the processed tobacco utilized in the manufacture of cigarettes is frequently of a density greater than is necessary for producing acceptable smoking products.          Various techniques, as will be subsequently discussed, for reducing the density of such tobacco have been proposed in

Abstract: CROWDING LUG TRANSFER CONVEYOR SYSTEM           ABSTRACT OF THE DISCLOSURE          A crowding lug transfer conveyor system has an infeed and an outfeed end with a primary conveyor surface serving to convey pieces therebetween. A plurality of lugs, each slideably mounted on a lug chain, are held at the infeed end and then released ahead of an incoming piece. An upstanding member on the lug is above the plane of the primary surface and the lug body is below the plane. A predetermined body length establishes the spacing and crowding distance at the outfeed end. Escapement mechanisms serve to release individual lugs on command both at the infeed and outfeed ends. At the outfeed end a plurality of lugs and pieces may be accumulated and spaced with the pieces then being metered in a singulated controlled manner. Caliper blocks in the lugs serve to grasp the lug chain when a lug is released with the lug chain continuously passing through the caliper blocks when the lug is being held in place awaiting release.

Abstract: ABSTRACT OF THE DISCLOSURE:           An adjustable electrical load bank which comprises an upper and lower horizontal, electrically conducting plates mounted parallel to each other on a frame and both electrically insulated from this frame.  The lower plate is fixedly mounted on the frame while the upper plate is movably connected thereto through four spring devices. Three vertical piles of disk-shaped carbon elements are disposed between the two horizontal plates and each have an electrical resistance between their respective upper and lower ends which varies with pressure applied thereon. An upper and lower pistons separated by an helicoidal spring are disposed in a vertical cylinder mounted on the frame.  The upper piston is associated with a manually operated cam while the lower piston is fixedly connected to the upper plate.  Upon operation of the cam, the helicoidal spring produces a force acting against a force generated by the four spring devices for applying pressure on the piles. An accurate adjustment within a range of light pressures on the piles is therefore enabled due to these reverse forces for thereby allowing to give to the pile resistan-ces corresponding values.  When the helicoidal spring is completely compressed, the cam can still be operated to apply relatively high pressures on the piles to vary their resistances accordingly.  The load bank is particularly suitable fox use in wide current range battery testers.

Abstract: TITLE:  A SOLDERING IRON HAVING IMPROVED HEAT         TRANSFER CHARACTERISTICS                  ABSTRACT       A soldering iron heating unit is constructed using a blade heater having a large surface area per unit volume, surrounded by a conducting rod to which a soldering iron tip is affixed.  The combined heater and rod assembly is contained in a tubular metal hous-ing.  The large surface area of the heater, in close proximity to the rod, allows very efficient heat transfer.  The heat transfer from the conducting rod can be preferentially directed to the soldering iron tip and away from the heating element by making the conducting rod of sufficient diameter to engage the tubular metal housing only at the end where the tip is attached.

Abstract: Abstract of the Invention The invention relates to a method of movably interlacing a heating conductor in a predeterminable position between textile layers.  Known methods provide that the heating conductor is fixed on one of the layers by a zigzag seam or adhesive tape anchorage, and that the covering textile layer is bonded to the bottom layer.  This procedure involves a high outlay for sewing machines or for sewing-machine-like laying devices for the adhesive tape.  There is a danger of the heating conductor being damaged during the sewing operation.  This is remedied by equipping one of two press plates with an electric heating device and with a pin template interposed between them.  A textile layer is applied over the pins and onto the support plane of the pin template and the heating conductor is laid upon it.  A second textile layer is also passed over the pins and on to the heating conductor.  At least one of the two textile layers is provided with a heat-sealable adhesive coating.  When the two press plates are brought together the excess pin length is received in an elastic overlay or in recesses or in pin guide means of the first or second press plate.  The heating conductor is displaced by pressure into the textile layers and the two layers are bonded together by heat.
