Abstract: SOLID STATE BALLAST Abstract of the Disclosure A thyristor/capacitor inverter bridge energizes the lamp circuit with a high frequency oscillating voltage derived from full-wave rectified line voltage.  Lamp current is regulated by a commutation circuit which is synchronized with zero crossings of the thyristor current. When power is first applied, an initialization circuit initiates a time delay to permit lamp warm up and then enables the high frequency inverter to begin energizing the lamp load.  A re-strike circuit generates pulses coupled to the commutation circuit to re-start it when the rectified line voltage falls below that which is necessary to sustain oscillation of the inverter.  Fault detection circuits are included for detecting faults such as loss of primary power, thyristor over voltage, and thyristor over-current for taking corrective action, such as inhibiting the inverter and commencing a new initialization sequence.  In addition, in the case of thyristor over-current, which may indicate that both power thyristors are conducting at the same time, the power thyristors are commutated.  A fault count circuit determines whether a predetermined number of such faults occurs within a preset time, and if so, the system is shut down and manual reset may be required.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an inhalation tube for an aerosol container comprising a tubular body adapted for detachable fitting to an aerosol container.  On said tubular body a delivery mouth-piece is fitted which is movable between retracted and extracted positions.  The extraction and retraction of said mouth-piece is brought about by means of a cap, rotatably mounted on the tubular body, which cap has actuating means associated therewith.  The cap and tubular body have openings of similar dimensions.  Rotation of the cap to bring the openings into register causes the actuating means to move the mouth-piece to an extracted position, whilst rotation of said cap to bring the openings out of register causes the actuating means to move said mouth-piece in a retracted, closed-off position wholly with the tubular body.  Such an arrangement enables simple functioning of the inhalation tube and ensures that hygienic conditions are provided insofar as the mouth-piece is closed-off when not in use.

Abstract: ABSTRACT OF THE DISCLOSURE In the combustion of waste mineral-bearing liquid streams, an improved type of construction for the combustion chamber, for the combustion of waste mineral-bearing liquid streams which permits continuous removal of solid parti-culate waste is disclosed.  An annular water channel is fitted inside of the outer shell of the combustion chamber at the bottom.  The bottom of the chamber is closed off with a funnel-shaped, inverted conical floor, having a drain out-let at its center.  An opening is provided in the side of the combustion chamber just above the bottom, for the exit of downflowing products of combustion. Water is supplied to the annular channel and flows through a longitudinal gap in the inner wall, to fall onto the funnel-shaped floor plate, to wash down all of the particulate matter that collects on the bottom plate, into the drain.  Thus, the waste is removed as it is formed.  The refractory lining of the chamber is shaped with an inwardly-directed flange to permit the flow of molten material down the refractory surface onto the funnel-shaped floor plate and to protect the water channel from direct heating by the flame in the combustion chamber.

Abstract: CUE DATA RECORDING APPARATUS     ABSTRACT OF THE DISCLOSURE         Apparatus is provided for recording cue data identifying characteristics of information recorded in tracks on a magnetic tape; fox example, the cue data identifying beginning, end and various predetermined portions of program material, such as an audio program, a video program, or the like.  The recorded information is played back, and a cue signal generator generates respective cue signals upon the occurrences of respective ones of the predetermined characteristics in the played back information.  For example, one type of cue signal is generated when the beginning of the program is played back, another type of cue signal is generated when the end of the program is played back, and various respective cue signals axe generated when different predetermined portions of the program are played back.  In addition to generating the cue signals, code signals having a predetermined relationship with the played back information also are generated.  For example, the code signals may represent the relative locations on the magnetic tape at which the predetermined characteristics (e. g. beginning, end and predetermined portions) of the program are recorded.  A memory stores the code and cue signals, and a format circuit produces cue data in a predetermined format as a function of the stored code and cue signals.  The cue data in this predetermined format -i-then is recorded on the magnetic tape in a track which differs from the tracks in which the information is recorded.  Alternatively, the cue data is recorded on a disc record, such as a master disc from which replicas subsequently may be made.

Abstract: ABSTRACT:         Generally in land mobile FM transmitters a speech signal is pre-emphasised between 300 Hz and 3 kHz where-after it is filtered to provide a sharp cut-off and in order to maintain channel integrity the maximum peak fre-quency deviation is limited.  In consequence as the level of the pre-emphasised speech signal increases it is limited to a maximum peak output level which corresponds to the maximum peak frequency deviation.  Heretofore the filters have had such a step response that overshoot and ringing is produced when filtering the amplitude limiter signals.  As the peak of the overshoot is treated by the frequency modu-lator as the maximum peak output level then the level of undistorted speech for frequency modulation is typically 60% to 70% of the maximum peak output level.  The level of undistorted speech can be raised to within 90% of the transmitter peak deviation by directly connecting the ampli-tude limiter to a filter amplifier which behaves as a level sensitive filter when the speech signal has been limited and prevents ringing and overshoot being produced.  The output from the filter amplifier is coupled to a low pass filter, typically a fourth-order Butterworth filter, via an attenuator which reduces the amplitude of the signal to prevent the onset of further clipping.
