Abstract: 1. A disc-braked wheel for small-wheeled rail vehicles, such as low-floor waggons, having : a hub (4) ; a wheel disc (3) ; a wheel tire (2) releasably connected to the wheel disc ; and radial annular friction surfaces which cooperate in one plane with the lateral flanks (15), used as friction surfaces, of the wheel tire and are disposed at an axial distance from the wheel disc and enclose the hub at a radial distance, and of which the annular friction surface disposed on the outside of the wheel is formed by the outer flank (8) of a first rotating annular member extending in the direction of the hub, the annular friction surface disposed on the wheel flange side being formed by the outer flank (14) of a second annular member whose external diameter is smaller than the internal diameter of the wheel tire at the wheel flange, characterized in that : - the first annular member is constructed on the outside of the wheel in the form of a one-piece attachment (8') on the wheel tire (2), - the wheel tire (2) is fitted from the outside of the wheel with a taper fit on the wheel disc (3), the outer annular surface (20) of the wheel disc (3) being constructed frustoconical and the inner wall (19) of the wheel tire (2) correspondingly frustoconical, - the second annular member, taking the form of a brake disc (9), on the wheel flange side bearing against the wheel disc (3) via spacer cams (13) distributed over a pitch circle, and - the brake disc (9) and the structural unit formed by the wheel tire (2) and the attachment (8') are clamped against one another and against the wheel disc (3) by means of axial screwed connections extending through the wheel disc (3).

Abstract: The invention relates to a method of the manufacture of dimensionally stable, liquid-impermeable, flexible press bands, particularly for wet presses of paper making machines. With known manufacturing methods for such press bands, the provision of a structured surface for liquid discharge on the outer surface of the press band, which faces the fibrous web or the felts, is achieved either by reversing the press band after removal from the casting mould so that the structured surface becomes the outer surface of the band while the smooth surface forms the inside thereof, or by grinding drainage ducts into the outer surface of the press band. But especially in the case of small band diameters, reversing of such cast press bands causes serious problems and entails considerable expenditure, wherein the risk of damage to the band cannot be excluded and grinding of the drainage ducts is just as expensive. To simplify the manufacturing process and to eliminate reversing of the press band after removal thereof from the casting mould, the inner wall of the centrifugal tube is provided with cavities and/or depressions which upon casting of the free-flowing mixture are filled therewith to form raised surface portions on the outer surface of the finished press band, so that in a subsequent pressing operation liquid to be discharged may be drained between said raised portions, and the completely cast press band is ground to finished size on the inside thereof.

Abstract: The compressor has a piston rotating in a cylinder and mounted on a shaft, together with control mechanisms in the cylinder inlet and outlet ports.  Each mechanism comprises a rotor (20) outside the cylinder (1) and housed in a sleeve with slots (37). The sleeve turns in synchronism with the shaft and the relative positions of rotor and sleeve are adjustable.  It can be driven from the shaft by gears, sprockets and chain or a toothed belt. Typically the drive can incorporate a non-round gear, so that the rotor shuts faster than it opens.

Abstract: Apparatus for converting a frequency division multiplex (fdm) signal to a time domain multiplex (tdm) signal in which a voltage controlled oscillator (21) whose output is a staircase of reference frequencies mixed by a mixer (20) with a received fdm signal. Each received frequency is output in turn at a common intermediate frequency from a bandpass filter 22 thereby forming a fdm signal after passing through a demodulator (23) and low pass filter (24). The conversion may take place in the optical domain by mixing optical reference frequencies with an optical fdm signal in, for example, a coherent heterodyne optical receiver.

Abstract: A microwave application chamber including a reactive and absorptive choke is shown and described. The absorptive choke is made of a material having the same or close dielectric constant as the material being treated so that microwave energy will pass readily from the material being treated into the absorptive choke. The interface between the absorptive choke and the material being treated is essentially transparent to microwave without reflections. This transparency permits microwave energy to be absorbed in the absorptive choke which otherwise would follow the waveguide created by the material being treated and exit into the environment.

Abstract: The bobbin winder (1), especially for delicate yarns (8), has feed rollers (11) and a powered bobbin spindle (4). A monitor (14) registers the yarn tension, and generates proportional signals to the control for the bobbin spindle and the reciprocating yarn guide (10). The yarn tension monitor has a single roller (16) on a cantilever arm (15) with a restricted movement. The monitor roller deflects the yarn path from the feed to the yarn guide, without additional deflection rollers. The bobbin winder, for delicate yarns, has a cantilever to support the monitor roller. The monitor has at least one sensor to register the bending movements of the cantilever, and generate a signal proportional to the detected movements. The cantilever arm can be a weighing beam, to register the force of the yarn on the roller, and generate a proportional signal. The cantilever beam is fitted with expansion measurement strips at its nominal bending zone. The bending beam can be within a housing tube, with adjustable limit stops to set the movement range. The winder has a number of bobbin winding heads, each with a drive spindle and a reciprocating yarn guide. Each bobbin winding head has its own yarn tension monitor, with a single roller, within a separate machine unit (13).
