Abstract: P 89 4700 DEINKING WASTE ELECTROPHOTOGRAPHY COPY PAPER ABSTRACT OF THE DISCLOSURE The toners used for printing in the electrophotography processes such as xerography or laser printing are removed from copy paper. In the process, the paper is pulped to form an aqueous slurry. The toner is removed from the paper with a dual system of a collector and a collecting chemical. The best collectors have solubility parameters similar to the toners so that the softened toner is slightly soluble in the collector. These include polystyrene, polyvinyl chloride and polyacrylates, e.g., polymethyl methacrylates. Other collectors which are operable but less satisfactory are polyurethane and polypropylene. The collector is in the form of prills, beads or sheets. The specific collector will depend upon the specific chemicals in the toner. There are a number of requirements for the collecting chemical. It should be substantially insoluble in water. It should have a melting point that is at or below the approximate softening point of the toner or collector. It should be a saturated aliphatic primary alcohol, a mixture of such alcohols, an unsaturated aliphatic primary alcohol, a mixture of such unsaturated alcohols, a saturated secondary alcohol, a saturated aliphatic primary hydrocarbon, a mixture of such hydrocarbons, or a mixture of hydrocarbons and alcohols. The process is operable at or above the melting point of the collecting chemical, and at a temperature at which the toner is softened, generally 38-75°C.

Abstract: ABSTRACT      Voice and alarm  signalling capability between supervisory personnel at monitor and control sites located at separated transceiver facilities of a (repeatered) multichannel communication network is provided by a multichannel multiplexed encode/decode scheme in which voice and/or alarm signals generated at one station ace digitally encoded and formatted so as to be inserted into the data stream. of the normally conveyed data traffic over the active channels of the network.  At the receiving terminal site, these inserted signals are removed from. the high data rate digital data stream. and delivered to decoding equipment which reconstructs the original voice and/or alarm signals for delivery to the audio equipment of station operation personnel.  The encoded signals are inserted as overhead bits for each active channel, so that a fault on one channel will not prevent the completion of transmission of the intended communication between terminal site personnel.     The present invention employs a voice/alarm  interface module at each terminal site where network operation personnel monitor and supervise network performance.  Each of these modules is coupled to receive and accept signals produced from. a conventional telephone handset, and includes tone signalling circuitry that generates a pair of tones to be used for station address signalling, and analog voice coupling circuits for voice signalling.  The analog signals are digitized via a companding A-D converter and formatted for delivery to the transcriver equipment inserted with each channel of the network for transmission.     Each module also contains deformatting and D-A conversion circuitry which receives the serial overhead bits from a selected one of the channels and reconstructs the original analog signals for delivery to the audio equipment of the terminal station

Abstract: ROTATION SENSITIVE PRESSURE REGULATOR     Abstract This disclosure relates generally to fuel delivery systems for combustion ignition engines and more particularly to devices for limiting exhaust smoke and/or the rise in engine torque.  When a compression ignition engine is operating at full speed and a load is applied to the engine, the engine speed decreases until a lug condition results.  As the engine speed decreases, a greater volume of fuel is delivered to the combustion chambers resulting in an inherent increase in the output torque of the engine and in the production of smoke.  A rotation sensitive pressure regulator solves these problems by using a movable spool valve.  Stability of the regulator is achieved by using a spring that adjusts the static force applied to the spool valve and a nondeformable actuator member.

Abstract: Improved Coal-Fired, Steam-Driven Locomotive Abstract A coal-fired steam locomotive powered by reciprocating steam engines.  The locomotive is a two-unit drawbar-coupled locomotive.  The units, which are designated as a power unit and a support unit, are arranged back-to-back, with each having a cab-in-front.  Operation of the locomotive is equally effective in both directions.  The power unit basically contains a furnace and combustion system, an ash storage system, a gas cleanup and exhaust system, a boiler and steam generator, steam engines, a jet condenser, and a control cab.  The support unit, on two 6-wheel trucks, contains a modular coal storage area, a stoker motor, a water storage area, heat transfer assemblies and fans for air-cooling circulating water, and a second control cab.  The coal-gasification furnace, steam boiler, and steam engines are all in a closed system.  Further, the steam engines of the locomotive are in the form of a four cylinder, balanced system for driving the running gear of the locomotive. The steam expansion cycle is compounded; two high pressure cylinders exhaust into two low pressure cylinders, with all cylinders sized for equal thrust. Spent steam is condensed, cooled on-board, and the water recycled through the boiler.  A condensing cycle is utilized to both obtain more power and minimize water make up.  A large water supply is carried on the support unit to minimize way side water points.  Condensing of the water is by jet condensing which takes place on the power unit and utilizes feedwater as the jet condensing means.  The heated water is pumped through a heat exchanger provided on the support unit before returning to the water supply tank.  In order to eliminate nuisance dirt, coal is prepackaged in large modules.  Up to three modules are placed over the stoker screw mechanism contained on the support unit.

Abstract: ABSTRACT OF THE DISCLOSURE         A buoyant swimming pool cover is deployable over the surface of a pool under the influence only of the rotation of a power driven roller that extends horizontally across an end of the pool.  The roller, which may be of square section, is driven by an electric motor through a flexible drive  means including a pulley rotatable with the roller. The roller is rotated to wind the cover onto the underside of the roller.  The roller is arranged below the water level of the pool so that upon reversal of the rotation, the buoyancy of the cover will tend to unwind the cover and allow it to be deployed.  The square section of the roller provides a number of points at which adjacent layers nip one another to pre-vent unravelling of the cover as the roller rotates.

Abstract: Heating Device for Utilizing the Skin Effect of Alternating Current ABSTRACT      An improved power cable for a heating system that utilizes the skin effect of alternating current, and a method and apparatus for joining lengths of the improved cable.  In one embodiment, the cable includes a stranded copper conductor (20) surrounded by a semiconductive layer (22) formed by carbonized tetrafluoroethylene (TFE) tape which is surrounded by a primary insulation layer (24) formed by pressure extruded, perfluoroalkoxy resin (PFA), the thickness of which is determined by an equation that considers the eccentric positioning of the power cable in a heat tube (14).  In a second embodi-ment, the cable comprises a central conductor (30) sur-rounded by a semiconductive layer (32), followed by a primary insulation layer (34) formed by pressure extruded PFA.  A shield layer (36) formed by a layer of semicon-ductor material (38) and several helically wrapped drain wires (40) surrounds the primary insulation layer.  A protective PFA jacket (42) is pressure extruded over the shield layer.  Lengths of the improved cable are joined by first removing predetermined portions of the insulating and semiconductor layers from a terminal end (50) and a feed end (52) of respective cable lengths.          The exposed conductors (30') are mechanically joined and covered by a spirally wrapped carbonized TFE tape (60).  An insulating layer (62) is formed over the junc-tion by spirally wrapping uncured, nonadhesive tetra-fluoroethylene tape with a 50% overlap and then heat fusing the layer.  Shield extensions (66), (68) are formed by spirally wrapped, carbonized TFE tape that extend into noncommunicating, isolated overlapped rela-tionship from the respective shield layers (38) of each cable end.  The entire splice is covered with a layer of insulation (73) formed by uncured, nonadhesive TFE tape which is subsequently heat fused.  The drain wire (40) from the terminal end is grounded to the heat tube.
