Abstract: A B S T R A C T       A test unit provides a test leakage current to an electric circuit containing a current-operated core balance protective device adapted to open the circuit upon the occurrence of a pre-determined leakage current.  The test unit provides a test leakage current of a magnitude selectable from a pre-determined range which is applied to the circuit under test by a switch which isolates the circuit under test whilst the test leakage current is being selected.  A time controller limits the application of the selected leakage current to the circuit so that the time-current characteristic of the test leakage current is below the threshold at which dangerous patho-physiological effects are to be expected.

Abstract: The Abstract of the Disclosure Closed cell phenol-aldehyde foam is prepared by a method which includes a novel frothing and curing technique.          An admixture containing a liquid phenol-aldehyde resole resin, a volatile blowing agent, and a surfactant is frothed to produce a stable froth containing closed cells.  The cell walls are formed of the liquid resole resin and the closed cells are expanded by the blowing agent in gaseous phase.     The froth is formed into an uncured shape and the liquid resole resin is cured to the solid state in the presence of an acid catalyst to produce cured closed cell foam.  The internal temperature throughout the shape during curing is above the boiling point of the blowing agent but less than 100°C. and is sufficiently low to prevent further expansion of the shape in an amount to rupture the closed cell walls and thereby form an open cell structure.  The liquid resole resin has a sufficiently low exothermic heat of reaction and the acid catalyst is present in an amount whereby the internal temperature of the shape during curing is less than 100°C. and within the aforesaid limits.  The improved closed cell foam thus prepared is also provided.

Abstract: COMBINE CROP FEEDING SYSTEM                   Abstract of the Disclosure A combine has a feeding system, for conveying crop material from a harvesting unit to the infeed rotor of a longitudinal axial flow rotary crop processing unit, including a feeder house employing a pair of augers, mounted side by side in an enclosed housing, and contrarotating at a relatively high speed.  The augers are cantilevered from a bulkhead at the inlet end of the feeder house and do not make contact with the housing.  The housing cross section does not conform to the cylindrical surfaces swept by the augers and there is also space between the augers themselves so that heterogeneous material can be conveyed within the housing on all sides of the augers.  Housing shape and clearances are designed so that there is a minimum of dead space in the housing and, with some assistance from fixed strippers, mounted inside the housing parallel to the axes of the augers, material is conveyed generally linearly at a speed nearly equal to the equivalent axial speed of the auger flighting.  A transi-tion housing, between the feeder house and infeed rotor casing is shaped to minimize dead space at the point of transfer from the feeder house augers to the infeed rotor, so that the moving elements (augers and rotor) do not lose control of the material being conveyed.  A feeder beater is used at the feeder house throat to strip material from the harvesting unit cross auger and assist in accelerating it in the feeder house.

Abstract: ABSTRACT OF THE DISCLOSURE A transducer assembly includes a first half wavelength double-dummy section having a pair of quarter wavelength ultrasonic horns and a driving element sandwiched therebetween.  A second half wavelength stepped amplifying section extends from one end of the first section and has a theoretical reson-ant frequency equal to the actual resonant frequency of the first section. When used as a liquid atomizer, the small diameter portion of the stepped am-plifying section has a flanged tip to provide an atomizing surface of increased area.  To maintain efficiency, the length of the small diameter portion of the second section with a flange should be less than its length without a flange. A decoupling sleeve within an axial liquid passageway eliminates premature atomization of the liquid before reaching the atomizing surface.  In a fuel burner incorporating the atomizer, ignition electrode life is increased by locating the electrodes outside the normal flame envelope.  During the ignition phase, drive power to the atomizer is increased to widen the spray envelope to the location of the electrodes.  A variable orifice controls combustion air flow in accordance with fuel rate while maintaining constant lower speed. Either three-step or continuous fuel rate modulation saves fuel and reduces pollution.
