Abstract: A machining method, for a CNC-lathe for forming a predefined thread in a work piece, includes the steps of: rotating the metal work piece around a rotational axis thereof; moving a threading tool along a longitudinal direction through a set of passes, wherein the longitudinal direction is parallel/coinciding to the rotational axis; oscillating the threading tool in a radial direction during a first pass and first frequency, the threading tool moving between a first radial distance (D1) and a second radial distance (D2), (D1) being greater than (D2); oscillating the threading tool in a radial direction during a second pass and second frequency, the threading tool moving between a third radial distance (D3) and a fourth radial distance (D4), (D3) being greater than (D4) and smaller (D1), and (D4) being smaller than (D2); and during a last pass moving the tool without oscillation in the radial direction.

Abstract: A projectile for fire arms formed in such a way that it includes a front portion of essentially convex axial cross-section that via a transition transforms into a rear portion of essentially cylindrical radial cross-section, which rear portion acts as a power belt for the projectile.

Abstract: An isolated human alkaline sphingomyelinase (Alk-Smase) or a variant thereof is capable of hydrolysing sphingomyelin. Methods are provided for isolating human Alk-Smase and for preparing human recombinant Alk-Smase. Further methods are provided for the use of the enzyme for the treatment of colon cancer.

Abstract: A vacuum urinal assembly includes a shell portion, operational means, and vacuum discharge means. In order to achieve a streamlined arrangement, the shell portion is formed as a substantially unitary body, whereby the operational means comprise a level sensor means and a vacuum-operated discharge valve in fluid communication with a pipe system. The shell portion is arranged to support the operational means within the shell portion.

Abstract: The invention depicts a detachable brush comprising a brush portion (60) and a fastening portion (50) that extends along a first axis (C). The fastening portion (50), in order to be retained by a handle, comprises a first surface (52a) being angled in a first direction such that a normal of the first surface has at least a component in a first direction along said first axis (C), and a second surface (53a) being angled in a second direction such that a normal of the second surface has at least a component in a second direction, opposite to the first direction, along said first axis (C). The invention further depicts a handle with retainer portions shaped to receive and carry the detachable brush.

Abstract: In a valve arrangement in pneumatic impact motors (10), the housing (40) of a distribution valve has the form of a plastic bowl (46) which is flanged outwardly at the opening and the bottom thereof. A flat valve (50) is movable between the bowl bottom, which forms one valve seat (51) of the valve housing (40), and a bowl cover member (53), which forms the other valve seat (52). The bowl flanges (47, 48) define therebetween a groove which connects with a delivery channel (39) provided in the impact motor (10), this channel delivering compressed air to the flat valve (50) mounted inside the bowl (46). The bowl wall located between the flanges (47, 48) includes calibrated side openings (57, 58) which control the delivery of compressed air to respective valve seats (51, 52) on respective sides of the flat valve (50), this air delivery being an adapted and calibrated delivery.

Abstract: A waste tank for a vacuum sewage system installed in a transport vehicle comprises a receptacle portion for receiving sewage up to a predetermined maximum filling level. The tank defines an inlet opening for admitting air and sewage to the tank and an outlet opening for exhausting air from the tank. The inlet and outlet openings are above the maximum filling level of the tank. The tank also comprises an inlet separator that separates air and sewage entering the tank by way of the inlet opening using the kinetic energy of the sewage, and thereby dissipates kinetic energy of the sewage so that sewage entering the receptacle portion of the tank does not do so in a violent fashion, such as to contribute to vigorous movement of the sewage or cause splashing.

Abstract: A waste tank for a vacuum sewage system comprises a top wall having a major portion and also having a generally cylindrical dome structure which projects upwardly from the major portion of the top wall. The horizontal sectional area of the dome is substantially smaller than the maximum horizontal sectional area of the tank. The top wall is formed in the dome structure with an inlet opening for admitting air and sewage to the tank and an outlet opening for exhausting air from the tank.

Abstract: The invention relates to a strip or sheet mill having working rolls, backup rolls and axially displaceable intermediate rolls positioned therebetween. Associated with the rolled strip of the rolling mill is a flatness measuring device (e.g., for measuring the distribution of the strip tension over the strip width), the output signals of the flatness measuring device being fed, together with signals representing the strip width, to at least two different evaluating members, one of these serving to deliver a regulating signal for adjusting the crown of the working rolls, and the other serving to deliver a regulating signal for adjusting the axial positions of the intermediate rolls.

Abstract: An electromagnetic proximity fuze is utilized to initiate the detonation of a charge in a projectile when the projectile approaches within a particular triggering distance of an electrically conducting target object. A transmitter is disposed in the nose section of the projectile to generate an alternating electromagnetic field in response to a transmitter signal. A receiver is disposed in front of the transmitter in a spaced relation to the transmitter. The alternating electromagnetic field of the transmitter directly induces an electromotive force in the receiver. The electromagnetic field of the transmitter also extends to interact with the electrically conducting target object to cause the object to generate an electromagnetic field that induces an interference electromotive force in the receiver.
