Abstract: An exhaust air valve for placement in a ventilation conduit through which air is exhausted from a space to be ventilated. The valve has a casing with a concave seat surface facing upstream of the flow through the conduit and having a central valve orifice. A convex valve element cooperates with the seat surface and when the valve is closed engages the seat surface along a line of contact surrounding the seat. The curvature of the respective surfaces is the same, at least along the line of contact to ensure a tight closure of the orifice by the valve body. When opening, the valve body slides along the curved surface and the upstream surface of the valve body exposed to the flow is also convex to guide the flow toward the center of the orifice. Several embodiments are illustrated including valves with cords for remotely controlling the valve and heat-sensitive tripping mechanisms which automatically close the valve in the event of a rise in temperature above a preset level. The closing movement may be pivotal about a pivotal connection maintaining the valve element in sliding contact with the valve seat or may be a sliding displacement longitudinally of a slot in one of the elements.

Abstract: The invention concerns an arrangement when detecting metal objects by means of a transmission coil 5 which generates an electromagnetic field to maintain the amplitude of the generated field constant. The transmission coil 5 is designed to interact with a receiving coil which is arranged so that an electromotive force is induced in the coil under the influence of the field generated by the metal object and the field generated directly by the transmitter coil 5. The transmitter unit contains an oscillator 1 which generates a sinusoidal signal which is sent to the transmitter coil 5. A negative feedback loop of the oscillator 1 includes a variable attenuation or amplification circuit 2 for regulating the amplitude of the oscillator signal. Said circuit 2 is controlled by a feedback circuit for feeding back the voltage across the transmitter coil 5. <IMAGE>

Abstract: This is a control method for large scale batch reduction of zirconium tetrachloride to zirconium metal. Solid zirconium tetrachloride is fed at least periodically into a sublimer and the sublimer heated to vaporize the zirconium tetrachloride. The vaporized zirconium tetrachloride is fed from the sublimer to a reduction vessel and a measurement is made indicative of this feed (e.g., the flow rate or the pressure in the reduction vessel). A condenser is used to conjunction with said sublimer and the temperature of the condenser is controlled to control the feed of the vaporized zirconium tetrachloride. Preferably, a flow restriction is used between the sublimer and the condenser to provide improved control.

Abstract: A self adjusting device interposed in the lever system of a friction clutch is disclosed. The device operatively connects a threaded adjusting ring and an axially shiftable actuating collar such that wear occurring in the friction surfaces of the clutch is automatically taken up during operation of the clutch. The self adjusting device includes a mounting bracket secured to the clutch cover. The mounting bracket includes a central U-shaped portion and a pair of flange portions, each extending outwardly from an end of the opposing sides of the U-shaped portion. A pin is retained in the opposing sides of the U-shaped portion of the mounting bracket. The pin rotatably carries a pair of hub members which effect the self adjustment of the clutch to compensate for wear of the friction surfaces. The U-shaped portion of the mounting bracket permits visual confirmation of correct installation and function of the self adjusting device.

Abstract: This invention relates to combustible or semi-combustible cases intended in particular for artillery ammunition. More specifically, the invention relates to combustible cases bodies obtained by spirally winding combustible paper tapes containing nitrocellulose and having an improved mechanical resistance relative to previous combustible tape bodies, thanks to the fact that the combustible paper tapes form three distinct coaxial layers in terms of their density and structure. The case bodies according to the invention are obtained by spiral winding around a mandrel 80 a sheet 70 consisting of an uncalendered combustible paper tape 41 and six calendered combustible paper tapes 42-47 with density between 0.9 and 1.2 g/cm3, the tapes being pasted to each other according to a helical angle alpha  such that the helical pitch P is larger than the width w1 of the tape 41 which thus forms a helix with turns which are not joined together. A calendered combustible paper tape 71 previously pasted with density lying between 1.15 g/cm3 and 1.3 g/cm3 is then spirally wound around the tube thus formed according to the a helical angle beta  such that the turns of the helix formed by the said tape 71 overlap. The tube thus formed is then cut to the desired length of the case body.
