Abstract: TITLE          Talking Tracheostomy Tube ABSTRACT OF THE DISCLOSURE           A talking tracheostomy tube according to the teach-ings of the present invention is shown in the preferred embodi-ment as including an inner cannula removably received within an outer cannula.  The tracheostomy tube further includes, in the preferred embodiment, a first cuff for sealing between the outer cannula and the trachea for substantially preventing air introduced through the inner cannula to escape from the trachea through the larynx.  In the preferred embodiment, air is intro-duced into the trachea above the first cuff by ports direction-ally drilled through the outer cannula and in fluid communication with a secondary passageway formed by and between the inner and outer cannulas.  The inner end of the secondary passageway is formed by a sealing obstruction integrally formed in the inside surface of the outer cannula adjacent the inner end for the seal-ing receipt of the inner cannula.  The outer end of the secondary passageway is sealed by a collar integrally formed on the outer end of the inner cannula which abuts and seals within a recess of a collar integrally formed on the outer end of the outer cannula.  In its preferred form of the present invention, the tracheostomy tube further includes a second cuff for sealing between the outer cannula and the stoma of the patient for preventing the secondary air introduced through the ports from escaping through the stoma in the neck of the patient.

Abstract: LOAD SENSORS                  Abstract of the Disclosure An electro-mechanical load sensor is in the form of a mechanical resonant system with electrostatically coupled electrodes.   The mechanical system is formed from a silicon wafer by a selective etching process and comprises a filament f between two terminations 12 and 13 carrying transverse plates M1 and M2.   Electrostatic (capacitive) coupling to plate electrodes E1, E2, E3 in a self-exciting circuit drives the system.   The resonant frequency for angular S vibrations with plates M1 and M2 in anti-phase varies with applied load L and is thus a measure of this load.

Abstract: ABSTRACT           In a digital video signal processing system including an image reproducing kinescope and a digital-to-analog converter (DAC), excessive kinescope beam currents are automatically limited in response to a control signal which varies a reference voltage for the DAC such that the peak-to-peak amplitude of analog video signals from the DAC is reduced.  A version of the control signal is applied to the output of the DAC with a magnitude and polarity for substantially negating unwanted shifts of the video signal black level during the beam current limiting mode.

Abstract: ABSTRACT OF THE DISCLOSURE          A support system for a multiple-span bridge constructed of reinforced concrete or prestressed concrete includes a primary structure and a secondary structure.  The primary structure bridges the spans between intermediate supports or between an abutment and an adjacent intermediate support and includes serially arranged support members elongated in the long direction of the bridge.  The width of the support members is a fraction of the full useful width of the bridge.  The secondary structure forms the roadway slab and is supported on the primary structure.  The secondary structure is made up of serially arranged individual roadway sections extending in the long direction of the bridge.  The roadway sections are supported by bearing members resting directly on the support members of the primary structure with the roadway sections being closely spaced in the elongated direction of the bridge as compared to the spans between the intermediate members and the abutments.      The roadway sections extend over the expansion joints between the support members.  The roadway sections can have a dimension in the elongated direction which is comparable to that of the support members or which is a multiple of the length of the support members.  The support members can be constructed in place on the bridge, while the roadway sections can be constructed at a single site and then moved over the support members into their final position on the bridge.

Abstract: IMPROVED TOUCH CONTROL ARRANGEMENT FOR AN ELECTRICAL APPLIANCE     ABSTRACT         An improved touch control circuit arrangement for electrical appliances having one or more electrical loads to be individually controlled in accordance with user selected power settings.  Each load has associated with it a power relay for coupling the load to an external power supply.  Each relay is coupled to a latch circuit operative when set to close the relay and when reset to open the relay.  The touch control arrangement includes a matrix array of touch keys having an input line for each row and an output line for each column to facilitate the multiplexing of touch key information to the microprocessor in conventional fashion.  However, the OFF keys are continuously enabled and coupled to the reset input of the associated latch circuit such that user actuation of an OFF key directly resets the relay control circuit for the associated load.  This enables the user to turn off the load independent of the microprocessor.  Each ON key is coupled to the set input of its associated latch circuit such that both actuation of the ON key and an enable signal from the microprocessor are required to set the latch circuit.  This prevents the inadvertent closure of the relays such as might otherwise result from microprocessor failure.
