Abstract: METHOD AND PROBE FOR           SENSING INTRACARDIAC SIGNALS     Abstract of the Disclosure Near field, localized, intracardial electromagnetic events can be reliably sensed within a human heart by sensing the event within the human heart at two or more closely spaced points, generally lying in a plane approximately perpendicular to the local depolarization vector in the proximate heart tissue.  The local electromagnetic event in the proximate heart tissue is sensed and discriminated from all other events within the heart, including events occurring at other locations within the same heart chamber, events occurring in adjacent heart chambers, events occurring in adjacent muscle or body tissue, and events occurring exterior to the body.  Thus, the P wave within the atrium can be reliably and distinguishably sensed from the QRST complex, the progression and sequence of heart events in the signal can be sensed at multiple locations wherein each event is reliably distinguished from the other.  In addition, events immediately following a cardiac stimulating pulse can be reliably observed.

Abstract: ABSTRACT OF THE DISCLOSURE      A solid-state electronic ballast circuit for supplying direct-current power to an electric discharge vapor lamp is disclosed.  The source-drain channel of a Vertical Metal Oxide Semiconductor (VMOS) Field Effect Transistor (FET) is connected in parallel with a fixed ballast resistor, the parallel combi-nation being connected in series with the lamp across a DC source.  A resistance network controls the conductivity of a bipolar transistor, which in turn controls the conductivity of the VMOS channel, in response to variations in both lamp voltage and current.  The ballast circuit may be manufactured as a part of the lamp bulb assembly, the ballast resistor taking the form of an incandescent lamp filament mounted in the same outer bulb with the vapor lamp arc tube.  A variable resistance may be employed to manually adjust the level of illumination delivered by the lamp, or a light-sensitive photo-transistor may be employed to deliver constant illumination.

Ghent ABSTRACT OF THE DISCLOSURE          Eddy current probes which are used to internally or externally inspect cylindrical components for localized defects have a main coil arrangement that induces and senses eddy current in the components.  In accordance with the present invention, the probe further includes an element associated with the main coil arrangement to generate a detected defect signal distinct from a detected noise signal.  The element can include one or more further coils mounted coaxially with the main coil arrangement so as to be between the main coil arrangement and the compon-ent to be inspected.  The element may alternately be a cylindrical con-ductive sleeve mounted coaxially with the main coil arrangement so as to partially shield the coil arrangement from the component to be inspected. An electrical phase shifting network may be connected to the one or more further coils to enhance the distinction between the signals.

Abstract: ABSTRACT OF THE DISCLOSURE:     An ophthalmic lens for persons suffering from severe ametropia.  The lens comprises a convex object-side front surface and an eye-side rear surface.  The rear surface consists   of a central region, a surrounding outer region;  and a transition region between the central region and said outer region.  The central region is developed as a surface chosen from the group consisting of aspherically developed surfaces of revolution and atorically developed surfaces, for optimal correction of aberrations.          The central region has a diameter such that provides a wearer with an object-side viewing angle of at least 20 degrees.  The transition region has a rear surface of such curvature that the entire rear surface of the lens including the central region and the outer region and the transition region, is continuously differentiable twice, in the sense that the second derivative of the curvature is a continuous function without steps, and the rear surface, in radial cross section forms a smooth curve without any abrupt change in curvature.  Such a lens has an appearance which is fully satisfactory esthetically and makes it possible to keep the overall magnification of the system consisting of the eye and the eyeglass lens closer to 1 than in the case of previously known lenses.  Aberrations are optimally corrected within a sufficiently large region, and no disturb-ing discontinuities in the fields of view occur.

Abstract: ABSTRACT OF THE DISCLOSURE           An input shaft of a press feed is rotated at a preselected speed and is drivingly connected to a cam that rotates with the input shafts.  Continuous rotation of the cam is converted to oscillating rotational movement of a cam follower through a preselected angle of rotation;  The cam follower is nonrotatably connected to an output shaft that is connected by an adjustable linkage mechanism through a pair of meshing gears to a driven feed roll.  The oscillating rotational movement of the output shaft is transmitted to the driven feed roll to advance the driven feed roll in contact with stock material through a preselected degree of rotation corresponding to a preselected feed length of the stock material to the press.  A clamp is provided for intermittently engaging the workpiece to prevent movement thereof.  The clamp is also cam driven through an air-actuated clamp cylinder.
