  • Patent number: 4455744
    Abstract: A precision resistor using a resistance metal film etched into a long serpentine strip cemented to a substrate. This substrate is a composite of rigid materials and plastics. The composite thermal coefficient of expansion of the substrate is given a non-linearity which in turn induces a stress related non-linear resistance change in the cemented film when the temperature changes. This stress-induced non-linear change is of approximately the same shape as the inherent non-linearity of the resistance versus temperature of the metal film, but opposite in polarity, over a wide range of resistor operating temperatures. Over the range, a much closer approximation to complete temperature compensation is obtained than previously.

  • Patent number: 4452873
    Abstract: A positive electrode for galvanic high-temperature cells with solid negative electrodes based upon Li, Mg, Ca or Al is produced by sintering a heavy metal sulfide (e.g. FeS, CnS), with a heavy metal powder (e.g. Fe, Ni). In the sinter electrode the heavy metal powder present in weight percentage of about 20% to 40% forms a rigid electrically conductive framework in which the active heavy metal sulfide is embedded. The free-pore volume of the electrode is about 50%.

  • Patent number: 4451154
    Abstract: A mixing device for forage and similar product has a rotatable, sloping mixing chamber with its closed rear axial end lower than its open forward axial end. The forward end receives and discharges the forage. Generally linear mixing vanes extend forwardly from adjacent the rear end of the mixing chamber for tumbling the forage during chamber rotation. An axial tubular housing within the mixing chamber encloses a rotatable axial auger, which communicates with the rear end of the mixing chamber to receive forage from the mixing chamber and feed it back toward and out of a forward end of the housing.

  • Patent number: 4448860
    Abstract: Non-aqueous alkaline cells, particularly those with Li anodes, are effectively protected against oxidation or carbonization due to inwardly diffusing moisture by providing them with a getter material of high specific adsorbtivity for gases. For this, there are particularly useful molecular sieves of the Zeolite type, of highly active aluminum oxide, or of silica gel. For retaining the getter, there can be used as receptor media the porous separator or the solid cathode material, and if appropriate also the solid electrolyte. In addition, the getter material can form an extrudable or injectable composite polymer with the plastic of a conventional housing seal, which functions as a water vapor barrier right in the sealing region.

  • Patent number: 4448333
    Abstract: A flexible tube and closure includes a hollow body which terminates forwardly in a closable nozzle and rearwardly in a sealed area to retain a paste-like material therewithin. An expeller is movable from the rear sealed closure towards the front opening to rearwardly squeeze the body to force the material toward the front opening. A flattened section extends rearwardly from the closure and connects to the expeller in a loop configuration to aid in grasping and functioning the device. Longitudinally extending strips including corrugations may be provided exteriorly of the body to facilitate operation of the expeller.

  • Patent number: 4448862
    Abstract: The coating of the microporous separators of lead storage batteries with a highly porous glass wool mat on the side facing the negative electrode plates promotes the electrolyte exchange at these plates and also counteracts the tendency toward crumbling and toward the formation of spongy lead (mossing). The glass wool mat may be applied in the form of a plate or a slab to conventionally made separators or it may take the form of a pocket into which the negative electrode plate is inserted.

  • Patent number: 4447376
    Abstract: In the manufacture of cells, e.g. of the system Li-Al/LiCl-KCl/FeS.sub.x, the finely divided raw materials for the electrodes and for an included ceramic separator are respectively mixed individually with the electrolyte salt, as well as with a synthetic plastic which is decomposable without residue under heat. The mixtures are rolled into plates, and the plates are heated above the decomposition temperature of the plastic after assembly. The plastic is preferably a polyhydrocarbon such as polyisobutylene and is preferably introduced by means of a solvent. It makes the powder mixtures plastifiable and suitable for rolling. This makes it possible to produce ceramic separators, which are fundamentally composed only of loose particle accumulations, in the form of plates of uniform structure and strength and to handle these in the same way as electrode plates during cell assembly.

  • Patent number: 4447379
    Abstract: To produce ceramic lithium nitride as solid electrolyte for galvanic lithium cells, Li.sub.3 N powder is first stirred together with molten Li-metal serving as binder, in a noble gas atmosphere. After cooling, the mixture is pressed into a shaped body and the shaped body is then sintered in nitrogen at temperatures of about 700.degree. C. This causes the Li-binder to also become transformed into Li.sub.3 N. The binding with lithium also makes the powdery starting material suitable for rolling, and shaped bodies such as tablets can be cut out of the ductile rolled product with high precision.

  • Patent number: 4443987
    Abstract: A unitary, coextruded panel adapted for use as the window of a structure, which panel combines light transmitting and light reflecting properties to permit passage of direct solar radiation at a low solar altitude and to prevent passage of direct solar radiation at a high solar altitude, and which also provides insulating dead air spaces.The panel comprises an essentially clear and planar inner and outer face, positioned along the inner and outer portions of the structure, respectively, and a plurality of ribs, connected to and extending between the inner and outer faces, some of which ribs are transparent, and some of which are opaque to solar radiation, which rib members are placed in a geometrical relationship which provides the selected light transmitting and light reflecting properties in relation to the solar altitude.

  • Patent number: 4442320
    Abstract: A central control unit (scanner) is connected across a set of subscriber loops. At each subscriber's premises, an individual subscriber terminal unit (STU) is connected across that particular subscriber's loop. To each STU are connected the various instrumentalities which are to be monitored by the system, e.g. fire alarms, burglar alarms, etc. FSK modulated signals in the upper part of the audible range are transmitted from the scanner to the STUs at appropriate times. The STUs reply by means of similar signals to indicate the status (e.g. alarm, or non-alarm) of the instrumentalities at the respective subscriber premises. This transmission and retransmission is interrupted when the subscriber's telephone is off-hook. In addition, a signal below the audible range (low tone) is produced at the STU, and transmitted to the scanner over the telephone loop if, but only if, all the instrumentalities at the particular subscriber premises are in a given state (e.g. non-alarm). If not, low tone is stopped.

  • Patent number: 4439502
    Abstract: In a galvanic solid cell, for example of the Na/SbCl.sub.3 systems, the cathode space is occupied by a self-supporting porous sinter framework of solid electrolyte material, in whose pores the active cathode material is retained. A porous structure can be united with the massive solid electrolyte-separator into a unitary sinter composite of high ion conductivity, to which, if desired, there can also be joined on the anode side a porous sinter framework for receiving the alkali metal. The meltable active electrode materials are introduced by immersion into the porous portions of the sinter composite. The porous solid electrolyte structure can also be used advantageously as the separator system for cells with molten liquid electrodes, e.g. of the Na/S high temperature cell type.
