Abstract: ABSTRACT OF THE DISCLOSURE:      A wood burning furnace includes a combustion enclosure made up of a lower closed generally rectilinear fire box which is defined at an upper portion thereof by a semicylindrical roof dome and a top cylindrical-shape smoke chamber supported on a rearward upright cylindrical smoke conduit and a forward upright smoke conduit, these conduits being supported on the fire box roof dome and open between the smoke chamber and fire box.  The combustion enclosure is supported inside of a furnace shell above a fan compartment in that shell.  The furnace shell and heating air baffles fastened to it are so constructed as to provide a heating air passage between the combustion enclosure and shell, and a blower in the fan compartment forces air from outside of the shell over the surfaces of the combustion enclosure and out the top of the shell to a location for use of heated air.      The configuration of the shell and air baffles on the one hand and of the combustion enclosure on the other is such that there will be a uniform rate of air flow over practically the entire surface of the combustion enclosure and over the entire involved surface of the furnace shell and air baffles to the end that heating and cooling of the combustion enclosure on the one hand and of the involved surfaces of the air baffles and furnace shell on the other will take place at a uniform rate throughout these entities so that no tendency for non-uniform expansion and contraction due to temperature change will result.

Abstract: ABSTRACT OF THE DISCLOSURE        A drop center railway car is provided with a continuous center sill having a depressed portion between the wheel assemblies.  The continuous center sill is dis-posed between a pair of light weight side walls which include side sills that are connected to transverse bolsters for proportionally distributing longitudinal and vertical loads between the two walls and the continu-ous center sill with the center sill supporting about three-quarters of the longitudinal load.  Crossbearers cooperate with the bolsters to prevent injurious bowing of the commodity confining surfaces of the light weight side walls, side sills and bolsters, which light weight is made possible by the forces being proportionally distri-buted between the three, rather than two, longitudinal members.  The drop center portion of the center sill is secured within a flat bottom portion of the car body thus lowering the lowermost cargo supporting surface the maximum amount permitted by government regulations thereby providing a very low center of gravity to the car.

Abstract: AN IMPROVED COAXIAL LOUDSPEAKER SYSTEM               MARSHALL D. BUCK            ABSTRACT OF THE DISCLOSURE           The present invention is an acoustic filter for use in combination with a coaxial loudspeaker system which includes a low frequency loudspeaker and a high frequency speaker which is disposed acoustically  in-front of the low frequency loudspeaker.  The acoustic filter includes a pair of parallel, perforated sheets which are separated from each other a suitable distance and which are joined together at their peripheries in any appropriate manner so that they enclose an airspace therebetween in order to form a single section filter.          The acoustic filter is disposed acoustically in front of the low frequency loudspeaker and acoustically in back of the high frequency loudspeaker so the acoustic filter inhibits the high frequency sounds of the high frequency loudspeaker from interacting with the internal sidewall of the conically shaped diaphragm of the low frequency loudspeaker.

Abstract: SOLAR ENERGY COLLECTING APPARATUS                         AND METHODS                 Abstract of the Disclosure In solar energy collecting apparatus the prob-lems of leakage due to differential thermal expansion and contraction between different parts of the collec-tor, duplication of parts, fixed factory costs, and the unnecessary use of expensive materials are solved by using collector members made using on-site roll-form-ing machines, the assembly of parts at the job site, and collector members that connect side by side, each having a sheet metal collector plate (11) as the prin-cipal part of a weather membrane above underlying sup-port structure.  A unique cover (13) and method of form-ing the cover enable use of relatively inexpensive film that is supported on side supports held to a pair of op-posed upper sidewalls (18 and 19) of the collector mem-ber so as to accommodate ready replacement of covers for individual collector members and ready attachment by joiner strips in an assembly of the collector members connected side by side.  A pair of opposed lower side-walls (23 and 24) of the collector member are longitudi-nally slidable in opposed attachment members (78) rig-idly secured to the underlying support structure (71 and 72) and have a bottom wall (15) connected to the ends of the lower passage to form an air passage to transfer heat from the collector plate.  The collector plate (11) is suspended from the support structure to allow for relative expansion and contraction of the collector plate and associated collector member struc-ture due to temperature changes.

Abstract: FOLDED BIT LINE - SHARED SENSE AMPLIFIERS                 ABSTRACT OF THE DISCLOSURE         A folded bit line-shared sense amplifier arrangement is described for sensing the logic state of an accessed memory cell in a dynamic MOS random access memory.  In the preferred embodiment, a shared sense amplifier is positioned between and coupled to first and second bit lines via first and second isolation transis-tors.  The same shared sense amplifier is also positioned between and coupled to third and fourth bit lines via third and fourth isolation transistors.  When the state of an accessed memory cell is to be sensed, its memory cell capacitor is coupled to a selected bit line and a dummy cell capacitor is coupled to the bit line adjacent the selected bit line.  A decoding circuit selectively activates the shared sense amplifier to sense a difference in voltage between the selected bit line and its adjacent bit line so as to determine the logic state associated with the accessed memory cell.  Then, the sense amplifier latches into this logic state for reading by the input/ output buss lines.  After the logic state is read, the selecting circuit enables the memory cell capacitor to be refreshed for further sensing by the sense amplifier.

Abstract: Jy/5678/05 ABSTRACT   In an axial flow rotary compressor a fluid n ow inlet    is circumferentially separated from a fluid flow outlet    by a dynamic flow splitter    comprising at least one toroidal chamber    providing a loop fluid flow path intersecting the path    of the rotor blades   such that any fluid leakage through the flow splitter flows around the loop flow path   .  Regeneration of the flow through the rotor blades  as they emerge from the flow splitter is thus facilitated.  The flow splitter    may comprise a number of contiguous chambers       whose apartures can increase towards the low pressure end of the flow splitter to compensate for the decreased density of the fluid.  The downstream walls    of the flow splitter chambers can be offset relative to the upstream walls   so as to provide a direct quasi-helical fluid flow path through the flow splitter to increase the enthalpy transport through the flow splitter.

Abstract: ABSTRACT:       The invention provides an improved class-B push-pull output stage comprising a first and a second output transistor of a first conductivity type, which stage is provided with a control loop for driving the second transistor in phase opposition as a function of the drive of the first transistor.  The control loop is adapted so that a stable quiescent-current setting is obtained and that the effect of poor high-frequency properties of a third transistor of a conductivity type opposite to the first conductivity type, which transis-tor is necessarily included in the control loop, is eliminated, so that a wide frequency range is obtained. Furthermore, steps are taken to guarantee a constant high input impedance.

Abstract: Abstract The invention provides a method and apparatus for forming uniformly  apertured, resilient plastic webs exhibiting fine-scale three-dimensional characteristics for fluid permeability.  The uniformity of aperturing is controlled by the character of the forming surface on which the plastic material comprising the web is subjected to a fluid pressure differential.  The forming surface is produced by superimposing and bonding a multiplicity of planar apertured sheets with coinciding apertures of dissimilar sizes, and then causing the uppermost surface to assume a radius of curvature greater than that of the lowermost surface.  This avoid the use of support members which contact the webs during forming thereof and disrupt the permeabllity thereof.
