Abstract: In a feeding device with constant adjustable tension for a yarn being fed from a yarn source to a yarn using machine, as a weaving machine, are provided: a fixed hollow body, around which the yarn coming from said source is wound into turns by an element rotating outwardly of said fixed body and coaxially thereto, to form thereon a yarn reserve from which the actual yarn is drawn, to be sent to said yarn using device, passing inside the fixed hollow body; an adjustable brake means cooperating with said fixed body, for braking the yarn with constant intensity, downstream of said yarn reserve; and a device associated with the fixed hollow body, for adjusting and keeping even the amount of said yarn reserve. The brake comprises a round element, formed by a solid central part and by a peripheral part with radial blades, arranged between an electromagnet mounted on said rotary element for winding the yarn, and the outer edge of said hollow body onto which the yarn gets wound, said blades being elastically bent at their ends with which they engage said edge, and said electromagnet housing the end of its core into an appropriate seat provided at the center of the solid part of said round element.

Abstract: For manufacturing a crank arm for a welded crankshaft a flat blank is gripped along its contour in a ring-shaped holder and is subjected to pressing forces acting perpendicular to the plane of the blank to produce, by extrusion, a crank pin stub and a journal pin stub projecting from opposite sides of the blank, respectively. Each stub can be extruded in two stages, the first of which results in a by and large axial material flow while the second stage produces a combined axial and radial expansion of the first formed stub to circular cylindrical shape. Simultaneously with the first extrusion a fillet merging smoothly into the stub is pressed into that lateral surface of the blank from which the stub is extruded. The fillet may extend continuously around the stub or alternatively it may be indented only along that part of the stub surface which is oriented towards the other stub. A pressing equipment for carrying out the method comprises a stationary lower tool with a segmented ring which determines the contours of the stub formed by the extrusion and of the surrounding fillet. The equipment comprises two interchangeable upper tools each having a pressing mandrel arranged to produce, in cooperation with an anvil at the bottom of the ring a substantially axial and a combined axial and radial flow of material, respectively, within the extruded stub.

Abstract: A cable type tire chain has traction sleeves on the cross members located only adjacent to the shoulders of the tire. The center portion of the cross members adjacent to the middle of the tire tread is free of traction sleeves. The traction sleeves are spaced away from the middle of the tire tread by either a coil spring through which the cross member cable extends or by beads attached to the cable. The cross members are attached directly to the side members of the tire chain by flat profile hooks formed from rectangular strips of metal, so that the cross members lie close to the sidewalls of the tire. The invention provides improved traction and reduced wear of both the tire and the tire chain.

Abstract: The disclosure relates to an electric buffing machine which is equipped with an X-shaped buffing pad that is mounted to a similarly X-shaped pad holder. The arms of the pad holder have a wedge-shaped cross section that acts as an air foil to create air currents that flow up between the arms of the X-pad. The casing surrounding the pad has a specially designed tunnel-like spiral diffuser that guides the air currents entered into a collection box. The casing also has a flexible skirt mounted to the lower side thereof, extending around three-quarters of the casing periphery, which closes the gap between the casing and the floor. The chassis has two pairs of wheels and is designed so that when the buffing machine is turned off, the machine rests entirely on the wheels with the buffing pad raised off the ground. When the machine is turned on, the air currents pull the pad to the floor with a predetermined pressure.

Abstract: The invention relates to a radar arrangement of the type comprising a transmitter which essentially continuously transmits a modulated carrier wave signal and a receiver for receiving the carrier wave signal reflected at an object (echo signal). The carrier wave signal is modulated with a code-generating signal (14) whose fundamental frequency, the code frequency, is determining for the range resolution of the radar. The code of the code-generating signal (14) is furthermore such that one bit in the code has a duration which is several times longer than the time of a period of the carrier wave signal and a code of several bits forms a block which is characterized by modulation of a carrier wave with constant frequency. The frequency of the carrier wave is changed between blocks so that the transmitter sends a block with a carrier wave frequency which is different from the carrier wave frequency or frequencies which the receiver is set up to receive. The receiver stores (14a) the transmitted code and correlates it with the received signal. When code correspondence (synchronism) is obtained this corresponds to a definitive position of the echo response reflector. By changing frequency between blocks, different range zones can be treated in different ways, that is to say different "types of radar" can be dedicated to different range zones. By this means, a radar arrangement is obtained which is adapted to cope with modern threat environments. The radar is difficult to spot, difficult to define and to disturb.
