Abstract: A VOICE SWITCH FOR HANDS FREE COMMUNICATION APPARATUS   Abstract of the Disclosure First syllable clipping typically associated with simple control circuits in hands free telephony, is substantially reduced by using a voice switch with non-linear response characteristics.  The voice switch includes field effect devices in transmit and receive variolossers for providing handsfree operation in communication apparatus. The field effect devices are non-linear in their response to a control voltage, and are thus controllable to provide rapid switching from an idle mode of operation, to an opposite mode of operation.  The control circuit generates a control signal for operating the voice switch in response to a.c. signals in a microphone circuit connected with a transmit path and in response to a.c. signals in a loudspeaker circuit connected with a receive path.  A circuit including another field effect device similar to the above mentioned field effect devices, is responsive to the control signal for generating a control voltage for controlling attenuation introduced in the transmit and receive paths by the respective variolossers.  This circuit generates the control voltage having first and second limits.  The first limit corresponds to operation of the voice switch in a quiescent or idle state and is adjusted with respect to operating temperatures such that the field effect devices are maintained at or near a threshold of conductance.  As a result, the variolossers are hyper-responsive to excursions in the control voltage from the first limit toward the second limit, substantially reducing first syllable clipping.                             - i -

Stepanek Owner: Pettibone Corporation Title: CAPS FOR HAMMERMILL ROTORS SECURED BY INDIVIDUALLY-REMOV-ABLE PAIRED PIN ASSEMBLIES     ABSTRACT OF THE DISCLOSURE In this improvement on the same inventor's invention of Canadian Patent Application 326,296, split-spring bushing which do not need to be removed are used instead of the removable bolt-and-sleeve pin assemblies of the earlier form of the invention.     The bushings are used in abutting pairs, each pair normally forming a pin securing the cap to -the arm or spider.   To remove the cap, the pair of bushings is shifted axially to place the cleavage plane between the two bushings in the plane between the cap and the arm One of the bushings then stays in the arm, while the other is removed with the cap.  The bushing thus removed can be pressed into the replacement cap, with care not to let it protrude into the space to be occupied by the arm.  After the replacement cap is applied to the arm its bushing is driven in to its full depth, forcing the other bushing across the further plane between the arm and cap.  The pair of bushings then form a pin assembly pinning the cap to the arm at both sides of the arm.

Abstract: ABSTRACT OF THE DISCLOSURE    In a speech processor for controlling a hearing prosthesis, an implanted electrode array stimulates the auditory nerve fibres of a patient by the application of electrical currents to selected electrodes in the array.  The processing system com-prises means for generating an input signal corresponding to a received speech signal, means for estimating the amplitude and frequency of the fundamental voicing and second formant com-ponents of the speech signal, and means for determining whether the speech signal is voiced or unvoiced.  Programmable means produce instruction data which in use causes the application of the electrical currents to selected electrodes in the array. The programmable means is programmed with data defining a pre-determined relationship between each electrode and a selected range of second formant frequencies based on psychophysical testing of the patient and causing selection of the electrodes based on the estimated-frequency of said second formant compo-nent such as to produce the desired percepts in the auditory-like sensations generated in the patient.  The selected electrode is stimulated at a frequency dependent on the estimated frequency of said fundamental voicing component for voiced speech signals and at a lower substantially constant frequency for unvoiced speech signals.  The programmable means also produces data which determines the level of stimulation of each selected electrode dependent on the estimated amplitude of the second formant component of the speech signal as well as on predetermined data relating to the sensitivity of each electrode implanted in the patient.  By providing an output signal in which both formant and prosodic information is present, the production of confusing precepts is avoided.

Abstract: PHOTOLYTIC SEPARATION OF ISOTOPES IN CRYOGENIC SOLUTION     ABSTRACT OF THE DISCLOSURE    Separation of carbon isotopes by photolysis of CS2 in cryogenic solutions of nitrogen, krypton and argon with 206 nm light from an iodine resonance lamp is reported.  The spectral distribution of the ultraviolet absorption depends on solvent.          Thus, in liquid nitrogen the photolytic decomposition rate of 13CS2 is greater than that of 12CS2 (because the absorption of 206 nm radiation is greater for 13CS2), whereas in liquid krypton and liquid argon the reverse is true.  The shift in ultraviolet spectrum is a general phenomenon readily characterized as a function of solvent polarizability, and exhibits behavior similar to that for vibrational transitions occurring in the infrared.

Abstract: RCA 74,251 ABSTRACT           A current source supplies current to an integrator representative of a difference between the instantaneous and average values of a video signal having a PCM data component time division multiplexed with an analog luminance component.  The integrator is enabled during the central portion of each PCM signaling interval and reset to a reference level during initial and terminal portions of the intervals.  Asymmetry of the peak-to-peak PCM signal levels with respect to the average signal level tends to result in asymmetrical excursions of the integrator output voltage relative to the reference level. This asymmetry is corrected by means of a charge source that supplied a predetermined quantity of charge con-tinuously or in discrete packets to the integrator during the central portion of each PCM signaling interval.  The integrator voltage excursions are thereby equalized and a substantially uniform probability of detection of the PCM data levels may be realized by means of a threshold device having a threshold level substantially equal to the reference level.
