Abstract: ONE AND A HALF BAND REFRIGERATED DISPLAY CASE         Abstract of the Disclosure A refrigerated display case for displaying refrig-erated products.  The display case is formed in a cabinet that has an interior area for holding the refrigerated products.          The cabinet has an access opening for enabling access to the refrigerated products.  A first air conduit extends around the cabinet and has inlet and outlet air openings for direct-ing air across the access opening in the cabinet.  During a refrigeration cycle of operation, the air traveling through the first air conduit is refrigerated by a set of evaporator coils.  A second air conduit extends partially around the cabinet along a path lying outwardly of the first air conduit.          The second air conduit has an outlet opening positioned adjacent to the outlet opening of the first air conduit.          During the refrigeration cycle, partially cooled air is emitted from the outlet opening of the second air conduit along a path across the access opening of the cabinet but lying outwardly of the air emitted from the outlet opening of the first air conduit.  The inlet opening of the second air conduit is positioned so that a portion of the air passing through the air circulating mechanism travels directly into the second air conduit and another portion of such air travels over  a  part of the evaporator coils before entering the second air conduit.  The display case can be operated either in a refrigeration mode of operation where the air is circulated in a forward direction through the first and second air conduits with the air passing through the first conduit being refrigerated or a defrost mode of operation where ambient air is circulated through the first and second air conduits in a reverse direction.  During the defrost mode of operation, ambient air is drawn through the outlet openings into the first and second air conduits.  The ambient air passing through the second air conduit helps to transfer heat to the air passing through the first air conduit and to the evaporator coils both by means of conduction and convection so as to assist in the defrosting of the evaporator coils.

Abstract: ABSTRACT OF THE DISCLOSURE         A latent heat storage device has a vessel receiving a latent heat storage medium and a heat exchange medium, the latter being immiscible with the former and being circulated from a collection chamber of the vessel, through the storage medium in direct contact therewith and back into the collection chamber.  In the collection chamber is disposed a heat ex-changer whose preferably vertical surfaces are in heat ex-change relationship with the heat exchange medium.  The exchanger has two separate heat carrier medium conduits in heat conductive relationship with each other, one for supply-ing and the other for withdrawing heat from the collection chamber due to heat-conductive contact with the heat exchange medium.  The basic advance in the art is in that a displacement of heat storage substance by the heat exchange medium does not impair heat exchange even on a long period of operation. The overall arrangement is very simple.  Six different em-bodiments are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE             The present invention relates to processes of producing transparent foamed plastics, particularly foamed acrylate and methacrylate materials, in the form of e.g. panels, molded articles, or as cores for laminate bodies.  Solid beads of transparent polymer material and containing a blowing agent are mixed with a reaction resin, softened by heating or swelling, and expanded to large pore size. During the blowing the beads may be displaced relative to one another.  Subsequently the reaction resin is com-pletely polymerized.  The so obtained foamed plastics panels, which have large closed cells with contiguous faces and a smooth, non-porous surface, are particularly useful as insulating and building material exhibiting good transparency and protection against loss of heat, especially for greenhouses.

Abstract: 14                  48,471 ABSTRACT OF THE DISCLOSURE     In  a  single  cycle  combustion  turbine  power plant, a dry catalytic NOx removal module is disposed in the turbine exhaust stack.  A waste heat exchanger system includes an economizer coil and a pair of evaporator coils on upstream and downstream sides of the NOx removal module to generate steam for injection into the turbine combus-tors.   Bypass  stacks  across  the  coils  are damper con-trolled to regulate the exhaust gas temperature at the entry to the NOx removal module.   The compressor inlet guide vanes are closed to increase exhaust gas temperature as  required  after  the  upstream  evaporator bypass  flow reaches zero and no longer controls gas temperature.  If the inlet guide vanes reach the fully closed position, reductant injection flow is shut off to terminate the NOx removal process under low exhaust gas temperature condi-tions.  A plant afterburner is operated to add heat to the exhaust gas if gas temperature is too low.

Abstract: ABSTRACT In hot-dip coating a ferrous metal strand with an aluminium/zinc alloy or like metallic coating medium, the strand is traversed from a furnace to a "galvanising" bath, through a duct terminating in a hood which dips into the bath.  While the strand is in the duct and the hood it is subjected to a gaseous reducing environment.  The gas consists of N2 and may have as much as 15% of hydrogen in it.  The temperature of the gas may be ambient temperatre. The pressure of the gas is just great enough to establish a plenum in the duct so that it may diffuse into the hood and there be quiescent and maintained substantially constant in quantity and composition.

Abstract: ABSTRACT A binary ink drop printer is disclosed of the type wherein continuously generated drops are electrostatically deflected to intersect either a target or a gutter. The printer includes M x N number of nozzles for generating drops and a like number of charging electrodes for charging drops to either a print level for flight to the target or a gutter level for flight to a gutter. A M x Nmatrix is used to couple voltages to the charging electrodes and thereby greatly reduce the number of electrical connections to a substrate carrying the M x N number of charging electrodes. Each charging electrode includes two sections. Application of a print voltage to both sections causes the generation of a print drop that goes to the target and application of a gutter voltage to either or both sections of the charging electrode causes the generation of a gutter drop that is collected in the gutter. One two section electrode is made using at least two partial cylinders. Another two section electrode is made by coupling a single electrode to a voltage divider network.

Abstract: ABSTRACT OF THE DISCLOSURE         A sweeping machine attached to a carrier vehicle comprises a sweeper unit attached laterally to the chassis of the said vehicle, between the front and rear wheels thereof.          In order to improve accessibility for maintenance work, and to provide for rapid attachment and release of the said sweeper-unit, the latter is accommodated as a whole on a supporting frame connected movably to the vehicle for the purpose of shifting the said sweeper-unit into a position outside the lateral contour of the vehicle.  In the case of a sweeping machine having an interchangeable structure comprising a frame carrying suction means for picking up dirt and arranged as a whole over the rear wheels of the said carrier vehicle, the supporting frame is secured to the said frame of the interchangeable structure in such a manner that it may be ex-tended laterally.  This operation is facilitated by a support means comprising a leg adapted to be attached to the said supporting frame, the said leg being supported by a roller which rests upon the ground on the side of the sweeper-unit remote from the vehicle.  If the interchangeable structure is arranged to be lifted by a leg, the carrier vehicle may be driven out from under the said structure, leaving the sweeper-unit connected thereto.

Abstract: ABSTRACT         ELECTRIC CABLES         In an electric cable for service at about 15kV and above, at least one extruded semiconductive screening layer comprises metal particles dispersed in a polymeric matrix.  The matrix adheres both to the particles and to the insulation and at least the polymeric material in the matrix (normally in the insulation as well) is cross-linked by the technique involving grafting silane side-chains to the polymer and then cross-linking them by hydrolytic condensation (the "Sioplas-E" process).  The proportion of dispersed conductive particles is sufficient to give a resistivity in a longitudinal direction of no more than 5000 ohm-cm.  The resistivity of the metal of the particles does not exceed 15 IACS and its hardness is not greater than 100 Brinell A.  The particles have an average length of at least 1 mm (normally exceeding the thickness of the screening layer) and an aspect ratio of at least 10:1.  By selecting the particles in this way, conductivity is achieved with a material that is still extrudable, and the use of metal particles rather than conductive carbon black avoids the severe detrimental effects on the cross-linking process of moisture carried by the reactive surface of the carbon black.

Abstract: ON-HOOK/OFF-HOOK DETECTOR CIRCUIT          ABSTRACT OF THE DISCLOSURE     An on-hook/off-hook detector circuit (10) is included within a telecommunications integrated circuit.  A tone generator power signal (VG) is monitored as a status signal to determine when a telephone switch hook is in either an on-hook or off-hook condition.  The tone generator power signal is subject to interference and transients which prevents direct utilization of it to indicate on-hook and off-hook conditions.  A resistor (20) and capacitor (22) are connected externally to the circuit (10) at a junction terminal (16) to provide a time delay following a transition of the status signal (VG).  The junction terminal of the resistor (20) and capacitor (22) is held at two transistor threshold voltages below the upper supply voltage (V+).  At the time of transition of the status signal VG the junction terminal (16) is disconnected from a current path such that the terminal (16) is permitted to charge the capacitor (22) through the resistor (20).  When the capacitor (22) has charged up to within one threshold voltage of the positive power terminal (V+) a transistor (48) is turned off thereby permitting the on-hook signal at line (50) to be driven negative thereby reliably indicating that the switch hook has been placed in the on-hook condition. The charging of the capacitor (22) serves as a time delay to eliminate faulty signal indications derived from noise and transients associated with the status signal (VG).
