Abstract: The image display equipment uses a screen of 16/9 format with conventional vertical and horizontal scanning circuits. The vertical scanning circuit provides a sawtooth signal with slope which is adjusted by applying a slope control signal to the input of the control circuit. The equipment also includes a receiver for receiving control signals from a remote control held by the user, enabling control of the amplitude of the scanning signals to provide a zoom effect on the image. The slope control system for the image is digital, and the vertical scanning circuit is such that position of the top of the image remains fixed when the slope is adjusted, but the position of the bottom of the image changes. The receiver can incorporate a processor which interprets the commands from the remote control in order to apply the required effects to the scanning control circuits.

Abstract: Four versions of clamps originally slidable along two generally parallel spinal rods (12,13) are swivel connected to three versions of transverse connectors (19) located between the rods (12,13). Set screws (31) lock the transverse connectors (19) to the clamps (22). Two of the clamp versions use interfitting rotational index locking detents at the swivel connections to fix the final orientation of the transverse connector (19) relative to the spinal rods (12,13). The other two clamp versions use locking tapers to lock the rotational index positions at the swivel connections to fix the final orientation of the transverse connector (19) relative to the spinal rods (12,13). One clamp version uses a separate set screw to fix the clamp on the spinal rod. One transverse connector has an open clamping head for installation directly onto the spinal rod without sliding it onto the rod from one end or the other.

Abstract: Modulation des impulsions de commande du faisceau (MIC) dans un tube émetteur RF (101) par un commutateur à semi-conducteurs (S1) connecté entre la source de tension (103) alimentant la cathode et la cathode (102) du tube émetteur. L'élément (104) de commande du faisceau est renvoyé à la source de tension normale de la cathode de telle manière que par la fermeture du commutateur (S1) entre les deux cathodes et la source d'alimentation de la cathode, la tension de l'élément de commande du faisceau est amenée au potentiel cathodique et provoque le flux de courant du faisceau, et que l'ouverture du commutateur (S1) génère une résistance cathodique équivalente très élevée qui polarise automatiquement le tube au niveau du point de coupure, ce qui évite d'avoir une source de tension 'hors circuit' séparée. La vitesse de déclenchement peut encore être augmentée par un commutateur de coupure (S2) connecté entre la cathode (102) et une prise du collecteur sur l'alimentation (103) de la cathode, ce commutateur (S2) étant fermé lorsque le commutateur (S1) est ouvert afin d'accélérer le retour du potentiel cathodique à une tension de coupure.

Abstract: If pressure constraints occur during the execution of
blood treatment, the pump flow rates are rapidly decelerated
to remove the pressure constraints so that the treating
operation will restore the normal state as quickly as
possible. After the pressure constraints have been removed,
the pump flow rates are restored at a preset acceleration
without causing any excessive pressure buildup due to an
abruptly increased load. If the pump flow rates immediately
after the start of operation of the processor are increased
through two stages of acceleration, the target flow rates can
be rapidly reached without exerting any abrupt load on the
processor and, hence, without causing an excessive pressure
buildup.

Abstract: The sensor has a controller (9) and operates in at least two states. The first state is determined by an applied supply voltage. In the first state an adjuster (5) rapidly matches the working level of a measurement device (2) to the dc signal level of a sensor signal (s1). In the second operating state an average signal value (sm) is determined. In the first operating state an output circuit (4) yields an output signal (s3) that is independent of the sensor signal and in the second state it yields an output (s4) that is dependent on a fluctuating superimposed sensor signal (s2).
