Abstract: A binary atomizing nozzle includes a housing having a liquid insert and a gas insert. The liquid insert has an interior chamber and a liquid inlet and a liquid discharge communicate with the chamber. A spin insert is positioned in the chamber so that liquid flowing from the chamber is given a rotational spin and exits the liquid discharge as a hollow cone. The spin insert is threadedly engaged with the wall of the chamber so that the liquid discharge constantly wets the wall portion of the flaring discharge. The liquid insert has an outer portion spaced from the gas insert and provides an axially extending annular chamber having a gas discharge. The liquid discharge is axially spaced a preselected distance from the gas discharge so that gas exiting the gas discharge flows along the outer portion of the liquid insert according to the Coanda effect and thereby atomizes the liquid exiting the liquid discharge.

Abstract: A voltage-to-frequency and analog-to-digital conversion circuit using a microprocessor-controlled capacitor charge-discharge scheme provides high resolution and low component count and is particularly suitable for use with resistance bridge transducers.

Abstract: A combination expansion shell and resin secured mine roof anchor assembly comprising an elongated bolt which carries rebar and an expansion shell. The assembly is inserted into a mine roof opening, in the back end of which is positioned a resin and catalyst cartridge. The cartridge is ruptured by the assembly allowing the resin and catalyst to gravitate downwardly, where they are mixed together by the rebar upon rotation of the bolt. The bolt is rotated a predetermined number of revolutions to obtain proper mixing of the resin and catalyst preparatory to setting, after which the continued rotation of the bolt in the same direction effects movement of the expansion shell into gripping engagement with the mine roof.

Abstract: A load recall valve has a mechanical memory which coordinates the releasing of the brake with the system pressure. The mechanical memory requires that the system pressure be at least equal to the system pressure just prior to when the brake was set. Setting of the brake prior to the load being taken off the system causes the memory to be activated. Setting of the brake after the load is taken off the system causes the stored memory portion to be erased.

Abstract: An improved descent device including a rotating spool on which is wound a cable is provided with a fluid rotation-retarding means having a plurality of vane members mounted for rotation in a fluid-filled chamber. The vane member is comprised of a vane shell receiving a vane core which is normally biassed in a radially inward direction and is extensible from the vane shell by centrifugal force. The retarding force depends on the contact surfaces between the vane members and the fluid which vary with centrifugal force.

Abstract: A process is described for the production of superconducting conductors of the type comprising a plurality of filaments of an alloy containing niobium and titanium as base materials and a composite matrix of copper, aluminium or alloys of these elements, in which the filaments are disposed, and which serves to stabilize the superconductor; the process includes at least a first phase of preparing a first superconducting conductor comprising:the said filaments and a first matrix of copper, aluminum or alloys of these elements;a second phase of preparing a strip of copper, aluminum or alloys of these elements of width substantially equal to the perimeter of the section of the said first superconducting conductor;a third phase of depositing a layer of brazing material on the outer surface of the said first superconducting conductor and at least on one of the surfaces of the said strip;a fourth phase of connecting the said first superconducting conductor with the said strip and for shaping the strip itself by plas

Abstract: A wind energy collection and conversion system includes a plurality of turbine assemblies. The turbine assemblies rotate on a common axis transverse of a base. A plurality of shutter assemblies are disposed in a circular orientation around each of said turbine assembly and are independently operable for causing wind current to be directed thereby for rotating said turbine assemblies. Five wall elements extend outwardly tangential to the periphery defined by the shutter assemblies and intercept the wind current and direct the wind currents toward the shutter assemblies. A roof covers the power plant and thereby increases the overall efficiency.

Abstract: A safety valve responding to overheating conditions of the surrounding atmosphere, more specifically a combustion gas inlet valve that closes when a fire declares. The valve uses a shape-memory element for detection and command. For the latter function it must be inside the valve, at the expense of sufficiently rapid detection of external temperature. This problem is solved by using a shape-memory element that is in close contact with the valve housing, e.g. countersunk in a groove in the internal wall of the valve housing, for facilitating conduction heat transfer.

Abstract: A rotary joint is provided which is particularly useful in deep-sea diving suits, and which can be constructed in such a way such that resistance to rotational movement or the potential for leakage, does not increase substantially with external pressure on the joint. Preferably, the joint has a sealing member, a retaining member, and a central member disposed axially between the sealing and retaining members. The central member has an annular first end dimensioned and axially slidably mounted on a retaining end of the retaining member so as to define a first variable volume chamber therebetween. The central member also has a second end with inner and outer extending annular bearing members, each concentric with, and normally rotatably abutting a corresponding sealing surface portion on the sealing member, so as to define annular side walls of a second chamber. The second chamber is interconnected with the first chamber.

Abstract: A mini disk holder has a first and second thermoplastic sheet sealed at the periphery thereof for providing a pocket between the sheets. A slit is provided in one of the sheets to permit a mini disk to be inserted into the holder. The slit sheet is adhesively secured to a panel in order to seal the slit and prevent further access to the disk. The other of the sheets includes a thinned groove line providing a weakened area which may be removed therefrom in order to provide an opening to permit access to the article.

Abstract: An ultrasonic liquid atomizer includes a piezoelectric transducer element mechanically coupled to an amplitude transformer and further comprises an atomizing disk mounted at the free end of the amplitude transformer. The atomizing disk and the amplitude transformer are so mutually matched that the vibration system of atomizing disk and amplitude transformer evinces the same resonant frequency as the transducer element, preferably about 60 kHz. Furthermore, the cross-sectional transitions between the transducer element and the amplitude transformer on one hand and between the amplitude transformer and the atomizing disk on the other are designed to be low in notch-stresses. An ultrasonic liquid atomizer so designed evinces both good properties of vibrations and furthermore advantageous long service lives. It makes possible a high specific flow rate and avoids cavitation and therefore spatters.
