Abstract: Abstract A unique carrier data operated squelch for use with a demodulator detector for phase shift keyed digital signals.  The counts transitions in the PSK signal by examining a narrow time window around the phase transi-tions.  The number of data transitions that fall inside and outside the window is correlated with a predetermined threshold.  The inventive carrier squelch permits parameter programmability and is particularly suitable for implementation utilizing a microprocessor.

Abstract: Abstract of the Disclosure A cable for cryogenic use includes an inner conductor and a solid polymeric insulator loosely positioned about said inner conductor above 0°C.  A collapsible spacer can be positioned between the inner conductor and the polymeric insulator to further space the insulator away from the con-ductor and thereby accommodate greater shrinkage of the insulator.  In fabricating the cable, the cable is sealed and pressure is applied to the cable to expand the insulation. The cable is placed inside a rigid cylinder having an inside diameter larger than the outside diameter of the cable.  The cylinder is heated to facilitate expansion of the insulation, and the cylinder is subsequently cooled while maintaining pressure to the cable.

Abstract: ABSTRACT OF THE DISCLOSURE   A modular machine including several removable components which arc structurally interconnected in a manner to result in a rigid unit which is inexpensive to manufacture and easy to service or repair. The modular machine includes as its basic components a base frame assembly an operator's control station, and a cab assembly. The base frame assembly comprises an open frame construction including opposed rectangular end members and opposed hollow rectangular side members. Ground-engaging wheels are mounted to the side members by using a unitized axle assembly including a hub and sprocket which extends into the interior of a side member. A fluid motor is mounted to the inner wall of each side member for driving the ground-engaging wheels connected to that side member. The operator's control station includes a front wall portion and rearwardly extending side wall portions. A generally U-shaped frame extends downwardly from the front and side wall portions for engagement within a complementary cavity formed by stepped inner walls on the side members of the base frame assembly. The cab assembly consists of an operator's seat attached to a box-like frame with the box-like frame being pivotally attached to the operator's control station. The cab assembly may be conveniently removed from the operator's control station or rotated to an out-of-the-way position thereby permitting complete access to the interior of the operator's control station. The base frame assembly, operator's control station and cab assembly may be conveniently disassembled to permit complete access to all parts of the machine for easy servicing, repair or replacement.

Abstract: AIR LIFTED AND PROPELLED VEHICLE          ABSTRACT OF THE DISCLOSURE          The disclosure concerns a vehicle which is both lifted and propelled by air flow.  The vehicle comprises an upper deck, a depending peripheral side wall and a flexible, perforated sheet secured beneath the bottom of the side wall, thereby defining an open plenum.  A propeller in an air flow directing cowl seats atop the deck and part of the air flow is directed into the plenum and the remainder of the air flow is directed to move the vehicle.  The underside of the upper deck disperses air in the plenum.  Alternatively, the propeller is part of a duct which directs air into and disperses it around the plenum.  The cowl includes an air dam for trapping reverse flowing air.  A rudder directs the motion of the vehicle.  The plenum narrows in width toward the front and diminishes in height away from the plenum in-let through the upper deck.  In all alternate embodiment, the cowl has louvered exits along both lateral sides, and selec-tive opening and closing of these louvered exits turns the vehicle, brakes it or even causes it to move in reverse. The main exit from the cowl is then provided with a shutter which is movable to control the speed of the vehicle and which when closed cooperates with the louvers for moving the vehicle rearwardly.  In another alternate embodiments, the vehicle has a plurality of separate ones of the plenums beneath its deck.  Finally, a train of the vehicles may be made, with a single airflow supplying air to all the plenums.

Abstract: ABSTRACT OF THE DISCLOSURE    An air cleaning apparatus produces by a corona discharge an air stream without mechanical section and removes impurity particles or contaminated particles contained in the air in the flowing course.  The apparatus has a plurality of duct collecting panel electrodes alternately arranged oppositely to each other at a predetermined interval to become air flow passages, corresponding panel electrode group, and a number of ionizing wires extending at the position isolated from the ends of the electrodes.  A value of voltage applied between the corresponding panel electrodes and the duct collecting panel electrodes is set to substantially one-second of the value of voltage applied between the ionizing wires and the dust collecting panel electrodes, and the length of the intervals between the correspondig panel electrodes and the dust collecting panel electrodes is determined to become a predetermined potential gradient in response to the value of the voltage applied between both the panel electrodes, thereby generating a corona discharge between the dust collecting panel and the ionizing wire to improve the dust collecting efficiency.  The dust collecting panel electrodes and the corresponding panel electrodes are treated with an ozone decomposition accelerating noble metal plating layer.  Activated charcoal ozne decomposing filter is arranged in the air stream outlet, thereby reducing the ozone flow rate.  Further, this apparatus has another second ionizing wires installed at a predetermined distance from the first ionizing wires substantially on extension lines from the respective dust collecting panel electrodes at the further outside position from the position of arranging the first ionizing wires.  Corona discharge is also produced between the first ionizing wires and the second ionizing wires, thereby increasing the treating air flow rate to improve the air cleaning efficiency in the room.

Abstract: ABSTRACT           Apparatus and method for the on-site, continuous preparation of aqueous solutions of polymers, especially aqueous solutions of partially hydrolyzed polyacrylamides, for use in secondary and tertiary oil recovery operations.  The apparatus comprises a polymerization reactor and a post reactor. Successive batches of a pre-prepared reaction mixture are continuously fed into the polymerization reaction in a manner to form zones or layers in the reactor, each zone or layer comprising a reaction mixture which has reached a different stage or level of completion of the reaction than the zone or layer below and above it.  The zones or layers are continuously moved through the polymerization reactor at a rate such that when a zone or layer reaches the outlet of the polymerization reactor, the reaction will have gone to substantial completion.  The zones or layers are continuously conveyed from the polymerization reactor to the post reactor.  Enroute to the post reactor, a polymer modifying agent is continuously introduced into the zones or layers from the polymerization reactor.  A second reaction mixture is established in the post reactor in which the extent of the completeness of the reaction taking place in the post reactor varies from the inlet to the outlet thereof. The second reaction mixture is continuously moved through the post reactor at a flow rate such that the reaction will be substantially complete when the outlet of the post reactor is reached.
