Abstract: INNER ELEMENT FOR A FLOW REGULATOR     Abstract of the Disclosure A valve for a flow regulator employed in a fluid system is disclosed.  The flow regulator includes a housing defining an internal chamber and a fluid inlet and outlet communicating with the chamber each adapted to be connected to the fluid system.  Mounted within the chamber is a recipro-cating piston that is actuated by an external master piston.          A backing element is also mounted within the housing.  The valve includes an elastomeric inner member including a body with a circumferential layer of elastomeric material bonded to the body.  The inner member is mounted between the piston and stationary backing member and upon being compressed by the piston, varies the flow area through the inner chamber.          To protect the interface of the outer layer and the body from fluid flow, a shield may be placed along the backing member and the upstream end of the inner member.

Abstract: Abstract of the Disclosure The present invention relates to method and apparatus for substantially reducing the effects of interference at a receiver between concurrently received first and second digital signals which use the same frequency spectrum.  Interference between signals is effectively reduced by transmitting the first digital signal in an uncoded form while concurrently transmitting the second digital signal with both reduced capacity when compared with the first signal and in coded form using a forward error correcting code such as, for example, a block or convolutional code.  At the receiver intercepting both digital signals, a suitable detection process is performed to decode the second signal and separate both signals.  The present invention is applicable to the simultaneous satellite transmission of an area coverage beam and a plurality of spot coverage beams or to increase capacity on a radio channel.

Abstract: Abstract of the Invention A method of hot forming bends or deflections in preconsolidated metal matrix composite panels comprised of unidirectional filaments of boron, borsic, alumina, or graphite in aluminum or titanium base metals without limitation of orientation of the filaments relative to axes of the formed bends or deflections.  The method consists of locating the composite workpiece between open male and female members of a forming die; bringing the workpiece and at least the die faces to a temperature of from approxi-mately 910°F. to approximately 935°F.; and closing the die members at a rate of from 5 to 12 mils per minute after both male and female die members are in contact with the workpiece and until the die members are completely closed.  By practice of this invention, metal matrix composite can be formed with bends or deflections well beyond the heretofore limitations, and without concern or regard to the relative orientation of filaments in adjacent layers or plies.

Abstract: ABSTRACT OF THE DISCLOSURE         Corona discharge electrodes are coated with compressed dielectric materials.  A corona discharge electrode is placed under tension and coated with a molten, viscous dielectric material, such as glass, while under tension.  The dielectric material is allowed to cool so that the dielectric material becomes bonded securely to the corona discharge electrode.  The tension upon the corona discharge electrode is released thereby causing a compression of the dielectric material adhered thereto.  The resulting dielectric coated corona discharge electrode has a substantially improved life and delivers substantially uniform currents.

Abstract: ABSTRACT OF THE DISCLOSURE          A monitoring apparatus is described which is especially useful for level sensing.  The apparatus includes a housing formed of light transmitting material and a monitoring lens on the housing.  A directional light source is mounted within the housing to direct the light emitted therefrom towards the monitoring lens.          A monitorable light sensitive device is also mounted in the housing, the device being disposed remote from the light path between the light source and the lens.        The monitoring apparatus of the invention is reliable and efficient in operation and overcomes the disadvantages of presently available apparatus which usually are mechanically actuated conducting devices or float-level devices read by observation.  These devices of the prior art are extremely limited depending upon the medium to be monitored.  For example, it is difficult to monitor acids and alkalies or electrically conducted liquids by presently available apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE       In the field of closed loop control systems, a reference signal input is compared with a feedback signal to provide an error signal which then initiates corrective action until the feedback signal duplicates the reference signal.  Hence, the reference signal may be appreciated as the set point at which the control system should operate.          The disclosure relates to a manual input reference signal circuit which may be used to input a desired reference speed signal into a control system circuit for a prime mover.          Provision is made for both local and remote manual signal input and priority logic is included for selecting the most appropriate reference signal.  Inhibit logic dictates the floor and ceiling for the range of prime mover operation.

Abstract: ABSTRACT OF THE DISCLOSURE              A toy vehicle and toy vehicle game are disclosed in which a plurality of controllable  toy vehicles collect current from conductor strips in a slotless track and switch lanes when current polarity is reversed.  A toy drone car is used in the game which collects current from the strips asso-ciated with the other cars and it includes an electrical circuit which insures that current of only a predetermined desired polarity is supplied to the motor in the vehicle to propel the vehicle in a forward direction around the track. As a result, the vehicle is driven about the track in a for-ward direction regardless of the polarity of current applied to the collector strips.  In addition, the drone car includes an automatic steering system which causes the drone car to continuously switch lanes in an apparently random alternating manner as it moves along the track.
