Abstract: Abstract of the Disclosure A single-pass body implantable lead for transvenous insertion through a single vein to simultaneously sense and/or stimulate the tissue of both the right atrium and right ventricle. The lead employs a single bifurcated connector at the proximal end.  Insulated conductors for the ventricle and atrium are branched from a single outer sheath.  The ventricular and atrial branches are established in fixed relation to one another.  The ventricular branch is of sufficient length that it has excess length for the largest heart.  The electrode of the ventricular branch is held within the right ventricular apex by tines. The atrial branch has a "J" shape imparted to the conductor coil.  The atrial electrode is maintained in position within the right atrial appendage by tines. The ventricular branch is sufficiently flexible such that any excess length is merely coiled in some convenient position.  The distal portion of the ventricular branch is made slightly more stiff than the proximal portion causing the excess length to loop within the atrium.  Stylets are used to guide insertion.

Abstract: A multiple stylus print head, e.g. for printing a document in a facsimile system, has at least two parallel lines of styluses with the styluses being offset from one line to the next. Each line of styluses is built up from several tiers of interdigitated conductor pins (C) having tips that constitute the styluses per se. The tiers of pins are held together by respective strips of insulating material (7) forming comb-like structures which are then stacked together in such a manner that the combs fan out from the line of styluses. A plurality of groups (G1, G2) of stylus line forming comb structures are stacked together into a single stack.

Abstract: ABSTRACT OF THE DISCLOSURE           A metal treating method melts the periphery of a weld and removes the molten portion thereof, to enable demounting of a metallic plate partially welded to another metallic member.  The method comprises the steps of forming an electric arc between a hollow electrode rod and the metallic plate to melt the periphery of the weld with arc heat.  The molten metal is then sucked up the hollow interior of the electrode rod.  A rod at the end of which the hollow electrode rod is mounted, is urged resiliently towards the metal, while being freely movable longitudinally. A sliding block is urged in the same direction as the rod. The apparatus causes the sliding block to be engaged with the rod to withdraw the rod as needed.  The procedure requires less labour and skill than former methods.

Abstract: ABSTRACT:        A digital duplex communication system for data signals having a power-versus-frequency spectrum compris-ing two side bands, located one each side of a symbol fre-quency, the system comprising a transmitter/receiver which includes an echo canceller. The received signal is sampled at a multiple of the bit rate and comprises in each symbol period a first time during which data is valid (true eye) and a second time during which data is invalid (false eye). The receiver includes circuitry to decode the data from the sampled signal during the true eye. The echo canceller is designed to be operative only during the sampling instant in the true eye and at one of the zero crossing instants in each bit period. Thus the echo can-celler is operative at the instants t1 and t2 but not at the instants t3 and t4 when no information is being extracted from the received signal. This enables the storage capacity of a look-up table type echo canceller to be reduced and the processing speed of a transversal filter type echo canceller to be reduced.

Abstract: ABSTRACT OF THE DISCLOSURE         Analog image data pixels are sampled and held to produce a box car wave representative of the image data.          Wave height differences are bridged by linear interpolation, with frequency enhancement imposed at the bridge junctures.          The modified image wave is thresholded and sampled at a multiple of the original frequency to provide an image pixel stream com-prised of both original image pixels having one or more inter-polated image pixels therebetween.         One or more intermediate image lines are interpolated by comparing binary image data, portions of which may be inter-polated, on a pixel by pixel or multiple pixel basis one line pair at a time.  The pixel comparison produces an address used to identify a specific image pixel pattern from multiple image pixel patterns stored in memory.  The image pixel pattern taken from memory is used to form the interpolated intermediate line or lines.
