Abstract: A railway wheel/rail squeal suppression, wheel/rail noise reduction and wear reduction arrangement includes a separate structure (14) carried by a rail. The separate structure has a saddle-like profile including a web portion (15) defining a running surface for supporting the wheel, and two flange portions (16a, 16b).

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: An anti-theft device (1) intended for vehicles belongs to a type, which is capable of retaining the vehicle brake in a braking condition, as long as it is activated, and which is non-interfering with the brake in an inactivated condition. The anti-theft device (1) comprises a lock rod (3) provided at one end with hook or crook (5) for gripping around a brake pedal arm (26), the lock rod (3) to a major extent consisting of a shank portion (4), which is releasably lockable within a lock housing (2), which in turn is firmly secured to the vehicle in the vicinity of the brake pedal. The shank portion (4), which is provided with a helicoidal groove (6), extends through the lock housing and through a rotatably disposed element (14) therein, the hole for the shank portion (4) through the rotatable element (14) having a helicoidal ridge (16), which is complementary to the helicoidal groove (6) in the shank portion (4) and cooperates therewith.

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 present invention discloses a vehicle tire, which radiates low external tire/road rolling noise and comprises a rim (1) to the periphery of which a multiplicity of in axial direction separated sub-tires (5) are attached, each of which has an outer diameter/sectional width ratio (2r/b), which is greater than 8. These individual sub-tires are, for further improved noise characteristics, entirely filled with soft rubber or a soft plastic material.

Abstract: The invention discloses a vehicle tire with reduced rolling noise emission. The tire tread is provided with one or more air-permeable channels or pores (6), which serve to neutralize air pressure differences between different parts of the tread surface in road contact, for example on each side of a tread block in a tread pattern. The invention also discloses how these channels or pores can be created by piecewise vulcanization of rubber or plastic balls or otherwise shaped rubber or plastic bodies of which the tread is built up so that communicating channels or pores remain between such bodies.

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.

Abstract: A water distributing arrangement attached to a road roller to prevent material from adhering to the roller's surface includes a curvilinear mat supported in contact with the roller's surface and extending for its entire width. Water is distributed to the roller's surface through the mat's interior from a spray tube extending for the length of the mat and is prevented from flowing out in an axial direction at the mat's ends over the opposite ends of the roller.
