Abstract: TWO POLE GROUND FAULT CIRCUIT PROTECTOR      Abstract of the Disclosure.           A two pole ground fault protector is constructed of a detector-control module sandwiched between a pair of circuit breaker modules having their manual operating handles tied together. The combined width of the pair of circuit breakers equals the width of the detector module. The latter is provided with both line terminals for the protector and these terminals are spaced by the width of the detector module which is the same as the spacing between panelboard line terminal stabs. Load terminals of the circuit beaker modules constitute the load terminals for the protector. A tie bar connecting the automatic tripping mechanisms of the circuit breaker modules together and extending through the detector module is actuated by an electromagnet in the detector module to simultaneously open both circuit breaker modules upon the occurrence of a ground fault.

Abstract: EXHAUST RELIEF SILENCING APPARATUS   FOR MARINE PROPULSION SYSTEMS                   ABSTRACT OF THE DISCLOSURE            A tuned exhaust gas relief system for marine propulsion systems, for example an outboard motor, includes a lower drive shaft housing coupled to a two stroke engine by a pair of inter-mediate stacked exhaust extension plates.  The housing directs the exhaust gas downwardly to a through-the-hub exhaust propeller for exit therethrough.  With the unit in reverse or idling, exhaust gases are trapped within the housing.  A pair of tuned exhaust relief passageways may be formed by cavities in the mating faces of the two extension plates with a pair of inlet openings in the lower wall of the bottom plate.  A baffle member may overlie the inlet openings.  The passageways define constant cross-sectional area channels which terminate in exhaust openings in the rear wall of the drive shaft housing.  A resonant cavity, which may be integrally formed by mating recesses in the opposed faces of the extension plates, is in close spaced relation to each idle exhaust passageway.  Connecting openings are distributed along the length of the common wall between the cavity and passageway.          An exhaust housing within the drive shaft housing forms an exhaust expansion chamber of high acoustical impedance between the lower ends of the exhaust pipe means and the upper wall extension plate assembly.  The idle exhaust passageways have a low acoustical impedance, so that the acoustical impedance mismatch between the chamber and the passageways attenuates the high frequency sounds.          The idle exhaust passageways may transmit the half wave frequency and even multiplies thereof.  The resonator cavity is selected to attenuate the particular half wave frequency, or an even multiple thereof, which because of physical space requirements may be present and not attenuated by the idle exhaust passageway means.

Abstract: DATA PROCESSING CIRCUIT OPERATING        ON BYTE-BY-BYTE BASIS            Abstract of the Disclosure A microprogammed processor which receives 16-bit words as input data from an I/O system, breaks down each received word into four 4-bit bytes, and performs all logical and arithmetic operations on a byte-by-byte basis.  The processed bytes may either be stored for further use or reconstituted into 16-bit words and outputted to the I/O system.  The processor includes two source busses for applying information to an arithmetic unit (AMU), a destination bus for receiving the AMU output, as well as circuits such as memories and registers for selectively applying AMU input information to the source busses and for receiving AMU output information from the destination bus.  Certain ones of the memories can both apply information to source busses and receive information from the destination bus on the same machine operation.            Microprogrammed controlled gating facilities specify the circuits that are to be connected to the busses on each machine operation.

Abstract: ABSTRACT OF THE DISCLOSURE           The ultrasonic imaging method and apparatus comprises an ultrasonic wave transducer supplied with recurrent multi-frequency energy pulses for pulse insonification of an object under investigation with ultrasonic waves.  Resultant echo waves from the object are directed onto the transducer for converting the same to electrical signals which are supplied to a signal processor which includes a variable bandpass filter.  One or more of the filter characteristics are varied as a function of depth from which the echo signals are returned for enhanced resolution and signal-to-noise ratio of the received signal.  Preferably, the filter is matched to the noise and signal spectra of the system.  For B scan operation wherein reverberated acoustic pulses are derived from a range of depths a time variable filter is employed for time varying operation thereof.

Abstract: Continuous Curing Method for Longitudinally Extended Products and a Device for the Application of this Method Abstract of the Disclosure A method of and an apparatus for continuous curing (vulcanization) of elongated products, such as cables comprising a conductor surrounded by a mantle of a crosslinkable material.  The cable is passed longitudinally through a curing tube in which the cable is first subjected to heating in a heating zone for heating the cable to curing temperature and subsequently  subjected to cooling.  The heating of the cable in the heating zone is carried out by means of heat radiation in a pressurized gas atmosphere and the cooling of the cable in the cooling zone is carried out in the presence of a gas under pressure so that heat is transferred from the heated cable in the cooling zone partially by radiation to the cooled wall of the tube and partly by convection to said cooled gas.          Thus the heating as well as the cooling of the cable is carried out in completely waterfree conditions.

Abstract: ABSTRACT OF THE DISCLOSURE           An intrusion alarm of the kind in which a radiation field is transmitted in an area to be supervised; the reflected field is received and compared with the transmitted field, and a comparison signal is produced the frequency of which is indicative of the speed of movement of an object in the supervised area.  A signal processor receives the comparison signal and generates an alarm if the comparison signal contains components in a selected frequency range.          The processor includes a unique filter block which removes unwanted frequency components outside the range.  The filter block includes a pulse generator which generates a constant amplitude pulse train,  each pulse corresponding to a pulsation of the comparison signal, and control elements which control the duty cycle of the pulse train so that as the frequency of the comparison signal increases, the average level of the pulse train first increases and then decreases.  The pulse train is integrated and operates an alarm signal generator when its average level rises above a preselected level.

Abstract: Abstract of the Disclosure The means of this invention is in combination with an underground sewage reservoir having a water-holding strata extending therearound adapted to receive water from the reservoir. A perforated conduit extends around the reservoir and through the strata and is adapted to receive water from the strata. A circulating fluid line extends through the conduit so that the cir-culating fluid will tend to assume the temperature of the water in the conduit. The circulating fluid line is operatively connected to a heat pump means. The method comprises the steps of: (1) providing an underground sewage re-servoir in a water-holding strata capable of receiving water from the reservoir; (2) connecting the reservoir to a source of relatively warm fluid sewage; (3) extending a conduit through the water-holding strata and around the reservoir to permit water in the strata to center the conduit; and (4) extending a circulating fluid carrying line from a heating  or cooling system through the conduit so that the circulating fluid will tend to assume the temperature of the water in the conduit.
