Abstract: A B S T R A C T      To detect the location of a marine pipeline or a cable by means of a vessel, acoustic pulses are trans-mitted by a submarine pulse transmitter carried by the vessel. These pulses, as well as the reflections of the pulses on the seabottom and on the pipeline or cable are detected by means of two detectors that are carried by two paravanes towed by the vessel. The signals received by the detectors are combined and the record of the combined signals is displayed. The signal parts that are represen-tative for the acoustic waves reflected by the pipeline are identified in the record by separate colours or various intensities of a single colour.

Abstract: ELECTRODE IMPEDANCE MONITOR FOR ELECTROCARDIOGRAPHY               ABSTRACT            A patient's own heart is used as a voltage source for measurement of EKG electrode impedance.  The amplitude of an EKG signal obtained while the EKG electrodes are shorted together with an impedance is compared to the amplitude of an EKG signal obtained under identical conditions except that the impedance short is not present.  The value of the inter-electrode impedance is then equal to one less than the ratio between the unshorted amplitude and the shorted amplitude times the value of the shorting impedance.  In a preferred embodiment, the value of the shorting impedance is made equal to the maximum permitted inter-electrode impedance. Then, if the amplitude or the EKG signal taken from a patient decreases upon temporary insertion of the impedance short to a value less than half of the EKG amplitude obtained without the impedance short, the inter-electrode impedance is too high.

Abstract: "Apparatus for mixing at least one additional gas into a main flow of gas"     ABSTRACT OF THE DISCLOSURE     Gas is mixed into a main flow of gas in a cylindrical conduit by means of one or more feed conduits. In order to achieve good mixing and avoid concentrations of the added gas, the feed conduit(s) have two openings for outflow of the added gas, which openings are spaced from the wall of the cylindrical conduit, are symmetrically located with respect to the axis of the cylindrical conduit and lie in a plane perpendicular to that axis. The axis of these openings are mutually spaced by less than one half of the internal diameter of the conduit.          The added gas emerges from the two openings in mutually opposite parallel directions, so that it tends to circulate around the axis. The arrangement has been found advantageous when applied to the feed of gaseous fuel to hot blast stoves of a blast furnace.

Abstract: COMPRESSOR LOAD CONTROL FOR   AN AUXILIARY POWER UNIT            Abstract of the Disclosure An auxiliary power unit for an aircraft drives an electrical generator and an air compressor.  The auxiliary power unit is primarily intended for operation with the aircraft on the ground when other aircraft power systems are shut down.  The auxiliary power unit may, however, be used in an emergency to supplement the main aircraft generating system, with the aircraft airborne.  When the auxiliary power unit generator is used in conjunction with the aircraft generating system, inlet air to the compressor is controlled to vary the compressor load on the power unit to minimize power unit speed changes and electrical frequency transients.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention discloses a novel cutting block for use in a die cutting machine and in particular, to cutting blocks which form a portion of an electrical path for die cutting machines.  The cutting block comprises a plurality of planar members, each member having a thickness between planes small compared to its length, the planar members being assembled to form an integral laminated structure, the laminated structure having substantially planar, broad opposing surfaces, and at least one rod member extending within said laminated structure, each rod member passing through at least two of the members, and each rod member being comprised of a material having a resistance to cutting below a predetermined die damage level.  Accordingly, as the cutting block is worn away, the rods and thimbles present cutting properties which will not damage the cutting die, and therefore provide a longer life and lower effective cost for the cutting block.

Abstract: COMMUNICATION SYSTEM FOR CONNECTING A   PLURALITY OF ASYNCHRONOUS DATA PROCESSING TERMINALS            ABSTRACT OF THE DISCLOSURE          A communications system concentrator intended to interconnect a number of asynchronous data processing terminals operating at different speeds among themselves, or to a high speed switching or communication network.  The concentrator uses as a time multiplexed loop a link with the terminals later duplicated for security reasons.  The number of terminals that may be hooked up may exceed that which would be allowed if all were active simultaneously.  For this purpose, a signalling or watch function is used in the concentrator to watch the state of each terminal.  This function which assumes the active or rest state of the terminals, is based on a low speed search for terminals at rest, on detecting the change in their states and on the allocation, in time sharing, of the time multiplexed transmission resource among the active terminals according to their needs.  The time sharing of the transmission resource is adaptive.
