Abstract: Abstract:         The dispersive effects of frequency selective fading in a digital, FM, or AM radio system are reduced by means of an adaptive equalizer comprising a cascade of feed-forward stages, each of which includes: a first parallel wavepath including a first adjustable attenuator; a second parallel wavepath including a second adjustable attenuator and delay device  a combiner is provided for combining the signals in the wavepaths and for coupling the combined signal to the next stage.  By a suitable selection of parameters, according to two unique relationships, a transfer function can be realized which can compensate for amplitude and delay distortions caused by minimum and nonminimum phase fades.

Abstract: FOUR LAMP MODULAR LIGHTING CONTROL             ABSTRACT The invention is directed to a circuit and a method for efficiently controlling the output illumination level of a gas discharge lighting arrangement having four or more gas discharge lamps with multiple ballasts.  Load side control of each ballast is provided by a timed interval controlled impedance, serially coupled between the particular ballast and its associated lamps.          A circulating inductor, coupled in parallel with each controlled impedance, provides a current path between the power source and the lamps at least during that portion of the AC waveform when the controlled impedances are non-conducting.  The invention is equally operable at both 120 volt and 277 volt AC levels without major component changes.

Abstract: ABSTRACT OF THE DISCLOSURE           In an ignition system having a glow plug, the filament thereof is supplied with power from a generator by means of a switch.  The power is controlled so that a constant glow temperature level is obtained, for example by means of predetermined resistance in the filament.  The arrangement is associated with a Wheatsone bridge which, during a short interval at the beginning of every heat current cycle, is switched on when generator power is not yet supplied to the glow plug.  The balance of the Wheatstone bridge, which indicates whether the glow plug is too hot or too cold, is registered for the present cycle by means of a comparator in which the balance is converted into a logical signal to be the basis of on/off regulation by the switch in the heating circuit of the glow plug.

Abstract: ABSTRACT OF THE DISCLOSURE           A device for the sterile storage of a catheter and the sterile advancement thereof a given length directly in a blood vessel, said device comprising a connecting piece connectable both to a cannula and to a transparent, flexible protective sheath, in particular a plastic bag, enclosing the catheter.  In order to allow continuous reading of the fed out catheter length the protective sheath has a length scale, which has its highest value nearest the connecting piece, and which is made so that the reading of the length scale against the remaining length of the catheter in the protective sheath corresponds to the fed out length of the catheter.   Further means are provided which allow withdrawal of the protective sheath from wrinkled position to stret-ched position without bringing the catheter with it.

Abstract: ABSTRACT      A method for cooling and liquefying a methane-rich gas stream, such as natural gas, is set forth wherein the methane-rich gas stream is heat exchanged against a single component refrigerant, such as propane, in a closed cycle and a multicomponent refrigerant, such as lower hydrocarbons, in another closed cycle in which the single component refrigerant is used to cool the multicomponent refrigerant subsequent to the multicom-ponent refrigerant's compression and between stages of its compression.  The additional cooling between stages of compression shifts compression load from the multi-component refrigeration cycle to the single component refrigeration cycle.  This shift of compression load allows the load on the compression drivers on both cycles to be balanced.  The ability to shift compression load is beneficial in cool ambient condition regions where the two cycles could be effected differentially.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel pump suitable for use in a water injection system of an internal combustion engine is described.  The pump controls the rate of flow of water injected into the engine.       The pump includes a variable pressure inducing means for pressurizing the water contained in the pump.  The variable pressure inducing means is responsive to negative back pressure developed in the intake manifold of the engine and varies the pressure of the water in accordance with changes in the negative back pressure of the manifold.  As the negative back pressure decreases, the pressure of the water increases which in turn increases the flow rate of fluid from the pump into the engine.  There is also disclosed a pressure sensitive nozzle for controlling the flow of fluid exiting from the nozzle as a function of fluid pressure.  The nozzle includes an auxiliary fluid flow path through the nozzle that has an inlet opening of variable size.  The nozzle further includes a pressure sensitive piston that provides a primary fluid flow path through the nozzle.  The pressure sensitive piston normally blocks the inlet of the auxiliary flow path.  In response to a pressure build up above the predetermined value in the primary fluid flow path of the piston, the piston moves thereby increasing the size of the inlet of the auxiliary flow path as the pressure build up in the primary flow path increases above the predetermined value.

A feeler arm for activation of the clock module is provided which controls the position of the switch and biasing is provided for urging the switch and the feeler arm to close the switch and operate the clock module when no external forces are provided on the feeler arm.  The feeler arm is secured within the timing device in a manner wereby a force of sufficient magnitude at the free end of the feeler arm in a direction generally opposed to the direction of the biasing device, causes the arm to open the switch, disconnecting the battery from the clock module.  The feeler arm allows the timing device, to be secured to a phone in a convenient location with the free end of the feeler arm being positionable to be engaged by a component of the phone which forces the feeler arm to open the switch when the receiver/transmitter is hung on the phone.
