Abstract: ABSTRACT OF THE DISCLOSURE     A method of and apparatus for processing audio signals in which a measure of amplitude of audio signals in a selected time period is obtained.  The audio signals for the selected time period are delayed until the measure of amplitude is obtained, and then the delayed audio signals are normalized using the measure of amplitude.  High frequency emphasis may be employed prior to obtaining the measure of amplitude.  Alterna-tively, a multi-channel system can be employed for processing audio signals in limited frequency bands. The method and apparatus are applicable in a variety of applications including hearing aids, audio storage media, broadcast and public address systems, and voice communications such as telephone systems.

Abstract: ENGINE CONTROL              ABSTRACT OF THE DISCLOSURE     Fuel flow and/or engine speed is electronically controlled in accordance with a rate-of-change (acceleration or deceleration) value computed from one or more sensed parameters such as accelerator pedal position, throttle position, engine speed, exhaust temperature, intake manifold pressure, fuel temperature, etc. as well as stored engine parameters.  A difference between a desired rate-of-change and a measured actual rate-of-change in engine speed is used to correspondingly change an engine control, for example a fuel control rack in a diesel engine fuel pump, a throttle valve in a carburetor, a timer for a fuel injection valve, a fuel valve to a turbine, or other control.  The desired rate of change in engine speed may be critically damped, for example by multiplying by a percent or other fraction of a difference between a desired fuel flow and a present fuel flow, so as to avoid overshoot.          The control may be operated in min-max, all-speed, cruise control or other special speed control modes, as well as incorporating altitude adjustment, pollution emission control, timing advance control, excessive speed control, fuel control recalibration, counting of selective numbers of pulses from a timing wheel with extension of time for slow speeds, manually selectable low idle adjustment, recordation of operation at excessive engine speed, operating time or other event, fuel consumption economy maximizing, and/or anti-tampering features.    In one particular application, the electronic control replaces a governor on a diesel engine and provides maximum power and torque control which may be changed by sensed changed operating conditions such as different transmission gear ranges.  A standard computerized control can be employed for different engines with different engine parameters and manufacturing variations compensated by factors stored in ROM during final engine testing.

Abstract: Abstract A portable machine for carbonating liquid contained in a bottle is adapted to support the bottle (5) by the neck (81) through a bayonet connection and for a seal (64) which closes the bottle neck to be driven into engagement with the bottle neck by a piston (60) actuated by the first burst of gas supplied to the injection nozzle (66).  The bottle is loaded into the machine through a front opening (6) and a cover (7) for closing the opening is interlocked with a gas supply valve (12) so that gas can only be delivered to the nozzle (66) when the cover is closed. The cover is opened and closed by rotating a knob (23) which is depressed to open the gas valve.  The knob (23) is coupled to the gas valve (12) through a device (27) which prevents the valve being opened if the machine is tilted at more than a given angle to the upright position. To prevent an insufficiently filled bottle being press-urised a vent (76) is provided through an element (61) carrying the bottle seal (64) and a float guided on the gas tube (65) carries a valve member (79) to close the vent (76) when a minimum level of liquid is present in the bottle.
