Abstract: ABSTRACT            An electric gas blast circuit breaker is disclosed which has two stationary contact pieces.  A switching unit is movable between closed and open positions for electrically bridging the contact pieces in the closed position and for electrically disconnecting the contact pieces in the open position whereby an arc develops when the switching unit is moved to the open position.  A gas blast device blasts a stream of gas through the arc when the switching unit is moved to the open position.  The switching unit includes a supporting body and a slide-contact ring made of an arc-resistant material.  The ring slideably contacts one of the contact pieces in the closed position and is mounted on the supporting body so as to be electrically insulated therefrom.  A plurality of elongated contact elements are disposed in the supporting body for electrically connecting the contact pieces when the switching unit is in the closed position.  There is provided an electrical connection between at least one of the contact elements and the slide-contact ring when the switching unit is in the closed position and also when it moves into the open position and continuously in all operating positions thereof.

Abstract: DIGITALLY ENCODED ABNORMAL TIRE CONDITION INDICATING SYSTEM     ABSTRACT OF THE DISCLOSURE           An abnormal tire condition indicating system comprising a telemetry unit mounted on each wheel of a vehicle and a central receiver.  Each telemetry unit comprises a piezoelectric transducer which is deflected with each wheel revolution when the tire profile is low.          Deflecting the transducer produces an electric pulse.  The transducer pulses are accumulated by an accumulator until a predetermined condition is met, such as stored charge reaching a threshold level.  When the predetermined condition is met, the accumulator produces an enable signal.  The enable signal enables a digital encoder to produce a digitally coded signal.  A transmitter modulates a carrier frequency with the digitally coded signal to produce digitally modulated radio transmission signals.          The central receiver receives the digitally modulated signals from each telemetry unit and produces an indicia of the occurrence of the abnormal tire condition at one or more of the wheels.

Abstract: Abstract of the Disclosure Apparatus for the dynamic in-circuit testing of digital electronic devices employs a hardware testing circuit that is set by a microcomputer which takes no direct part in the test, so that the test hardware speed is not limited by the computer speed.  The apparatus comprises a library of devices corres-ponding to the devices to be tested, the library including a ROM containing the information regarding the devices needed by the microcomputer for its purpose.  An internal interface or router receives signals from the test device that are input signals to its terminals and routes them directly to the corres-ponding selected device in the library where it becomes an input to that device also.  Signals from the test device that are output signals are routed instead to a comparison block where they are compared with the respective output signals from the library reference device.  The signals at each corresponding pin of the two devices are compared and upon the presence of a fault the apparatus stops and identifies the pin or pins on which a fault has been detected.  An external interface is provided to shift the signal levels as required between the test device and the TTL logic devices of the apparatus.  The signals are sampled. during timed periods to account for different propagation times through the apparatus, and different operating speeds of the devices.  Provision is made for external or internal clocks, reset and ground connections.

Abstract: ABSTRACT OF THE DISCLOSURE           A simplified automatic error correction setup system is coupled to the remote control multiplex/demultiplex circuitry in a color camera to generate and store respective error correction control voltages for selected operating parameters during a camera setup mode, with subsequent automatic retrieval of the stored error correction control voltages during camera operation.          The automatic control voltages are digitally generated from incoming error signals via a control system loop generally formed of an error selector switch, a digital register, a digital-to-analog converter (DAC) and a random access memory (RAM).  The register and/or RAM data are converted to analog control vol-tages via the DAC for each parameter (i.e., channel) being auto-matically corrected, which voltages are linearly summed with the corresponding control voltages.  During the automatic setup mode, the RAM contents are updated via the register for any existing errors in the specific operating parameters.  The register is then disabled and the updated RAM cyclically read out continuously during the camera operating mode.

Abstract: ABSTRACT A pneumatic run-flat insert for a pneumatic tire is provided with circumferential sections having different radii. During vehicle operation in a run-flat condition the different insert radii cause a vibratory disturbance at a wheel axle that alerts the driver of the existence of a run-flat condition or an abnormally low-pressure condition in the tire. During normal driving conditions there is clearance between the insert and the tire liner and no warning vibrations will occur in the wheel axle.     In various embodiments of the invention the different insert radii correspond to two or more ply sections in an insert ply having different cord angles. A relatively high cord angle ply section will furnish a relatively larger radius than the ply section with a rela-tively low cord angle.     In further embodiments of the invention a pneumatic or non-pneumatic run-flat insert includes one or more bumps on the insert crown formed of rubber strips for example that furnish the insert with an out-of-round condition that causes a similar vibrating disturbance to warn the driver of a low-tire pressure or run-flat condition.

Abstract: : 11 :     ABSTRACT OF THE DISCLOSURE      A spool mounting apparatus, particularly suitable for automatic, unbuffered tape transport systems, permits a reduction in the handling of spools during loading sequences.      A spool inserted through an opening into a cavity within a housing, is guided into a preliminary position by a detent pin.  The opening possesses a spring biassed closure member, which is mechanically linked to a free running disc member over which the spool may locate.      Motion of the spring biassed closure member towards a closed position effects displacement of the free running disc member towards the hub, thereby clamping the spool disposed therebetween.  Subsequent rotation applied to the hub is therefore transferred to the clamped spool and the free running member.
