Abstract: Abstract The battery of the present  invention comprises a container having a plurality of cells including at least two positive terminal cells and at least one negative terminal  cell.    Each  cell  of the  battery contains  a plurality of alternating positive and negative electrode plates containing active material.  The positive electrode plates of each positive terminal cell are electrically connected to their associated positive terminal.  The negative electrode plates of both cells are connected to a common negative terminal.   The thickness of each of the positive plates in each of the cells is varied to achieve different  discharge  characteristics  at  each  positive terminal output.  The battery described above is connected via a set of switches and cables to the electrical system of an automobile.   One of the positive terminals of the battery is connected to the starter system while the other is  connected  to  the  auxiliary  power  circuits  of  the automobile such that the battery power to the starter and to the auxiliary circuits are electrically isolated from each other.  Thus, if the user drains one portion of the battery  by  running  the  auxiliary  circuits,  the  other portion of  the battery connected to the  starter will maintain its charge.  The generator is connected to both portions of the battery to simultaneously charge both cells of the battery when the engine is running.

Abstract: PAVING MACHINE HAVING TRANSVERSELY AND LONGITUDINALLY ADJUSTABLE GRADE SENSORS                          ABSTRACT         A paver of the floating screed type which is capable of operating with screed extensions  for laying down pavement at various widths includes a self-contained, stowable and extensible grade reference system with a wide, planar adjustment range.  The grade reference system provides an adjustment  range for posi-tioning a grade sensing device on either or both sides of the paver both  forward  and  transversely outward  from  a  selected support point on the paver.   The grade reference system has a pivotally outer support member which permits the sensing device to become positioned at any selected setting of an arcuate path forward of a rearward position in substantial alignment with the leading edge of the screed to a forward position determined by the length of the member.   The pivotal adjustment range of the outer support member is augmented by  a transverse adjustment range effected by an extension or retraction of a corresponding support member to shift the pivot axis of the outer support member respectively outward or inward.   The combination of the two adjustments provides for a mix of anticipatory grade change sensing combined with laterally outward extensions of the screed beyond the full extension range of the screed.

Abstract: TITLE          METHOD OF MAKING SHAPED CERAMIC COMPOSITES            WITH THE USE OF A BARRIER                               APPLICANT   LANXIDE TECHNOLOGY COMPANY, LP                              INVENTORS                Marc S. NEWKIRK     - and -Robert C. KANINER           ABSTRACT   In the present invention, there is provided a method for producing a self-supporting ceramic body by the oxidation of a parent metal to form a polycrystalline ceramic material consisting essentially of the oxidation reaction product of said parent metal with an oxidant, including a vapor-phase oxidant, and optionally one or more metallic constituents. The method comprises the steps of providing at least a portion of said parent metal with a barrier means at least partially spaced from said parent metal for establishing at least one surface of the ceramic body, and heating said parent metal to a temperature above its melting point but below the melting point of the oxidation reaction product to form a body of molten metal. At that temperature, the molten metal is reacted with the oxidant, thus forming the oxidation reaction product. At least a portion of the oxidation reaction product is maintained in contact with and between the molten metal and oxidant to transport the molten metal through the oxidation reaction product toward the barrier means and into contact with the oxidant so that the oxidation reaction product continues to form at the interface between the oxidant and previously formed oxidation reaction product optionally leaving metal dispersed through the polycrystalline material. The reaction is continued to the barrier means to produce a ceramic body having the surface established by the barrier means. A composite is formed by superimposing a barrier onto a filler material, such as a preform, and infiltrating the filler with the polycrystalline ceramic matrix grown to the barrier means.

Abstract: Electro-optical components and semi-manufactured articles, and method for making them. A light conducting layer is formed from a poleable or poled glassy polymer material, which has an under ionizing radiation definitively destructible e/o activity. A selective irradiation under a parallel beam will give sharp transitions (C, D) from an e/o active area (2. 1) or an area which can still be activated to an e/o non-active area. The buffer layers (3 and 5) can also consist of suchlike irradiated material. A suitable positioning of the electrodes (4 and 11) between which by means of a difference in voltage applied across the connections (12 and 13) an electric field with a sufficient intensity and/or uniformity can be induced extending into the border area, on both sides of the transition planes (C, D), will make sharp inducible refractive index transitions possible. This is utilized with e/o inducible waveguides in thin layers to obtain sharp lateral definitions, and in an optical intermediate switch.

Abstract: HIGH-EFFICIENCY FURNACE FOR MOBILE HOMES                   ABSTRACT OF THE DISCLOSURE    A furnace utilizing, in the upper portion of its cabinet, a blower acting downward through a separator opening to circulate room air past a combustion chamber whose gases flow upward through a sideward-positioned broad radiator member which reaches up to the flue.  A substantial increase in efficiency results from drawing the combustion gases out of the combustion chamber at the side opposite to the lower end of the broad radiator mem-ber, and interposing therebetween, directly beneath the separator opening, a plurality of tubes which serve as an intermediate heat exchanger.  A still greater increase in efficiency is achieved by utilizing, instead, a finned tube heat exchanger across and be-neath said separator opening; its heat transfer may be so great as to result in condensation of water vapor in the combustion gas.  To purge this, a motorized inducer-blower is used in the inlet air system, driving the condensate through the finned tube heat exchanger to an appropriate drain.
