Abstract: The fail-safe brake linkage includes a hydraulic cylinder acting upon first levers. The first levers are rotatably mounted on a respective shaft. Also rotatably mounted to each shaft is a plurality of levers connected to brake activation rods. Each first lever is biased against a respective cylinder rod of the hydraulic cylinder. During vehicle operation, hydraulic pressure is supplied to the hydraulic cylinder to extract the cylinder rods against a respective first lever, causing each first lever to assume a position which allows normal operation of the brake connecting rods. Should the vehicle lose hydraulic pressure, the hydraulic cylinder retracts, thereby allowing the biased first levers to assume a position which results in the automatic applying of the vehicle brakes.

Abstract: In a method and apparatus for producing half-tone printing forms with screens having arbitrary screen angles and screen width, screen dots are exposed on a recording medium by means of a recording element whose exposure beam is switched on and off by a control signal. The recording medium is sub-divided into a plurality of areal elements which are exposed or not exposed by the exposure beam as a function of the control signal. All areal elements exposed in a screen mesh of the rotated screen to be recorded form a respective screen dot. At least two matrices in the form of matrix memories are provided, the individual matrix elements thereof having screen threshold values allocated to them. The screen threshold values forming a screen hill represent the periodic basic structure of a screen mesh and are different for at least one tonal range in the individual matrices. During recording, those matrix elements in the individual matrices whose positions within the respective matrices correspond to the positions of the swept areal elements within a screen mesh are identified. The screen threshold values of the identified matrix elements are called in. Controlled by a random generator, one of the called screen threshold values is randomly selected and compared to an image signal value acquired by means of scanning an original. The control signal for the exposure beam is derived from the comparison, whereby a decision is made on the basis of the signal comparison as to whether the corresponding areal element is to be exposed or not as part of a screen dot.

Abstract: An electron gun (10) that suppresses the non-linear space charge forces and phase-dependant focusing forces that are chiefly responsible for the high emittance of conventional electron guns. The gun comprises a resonant microwave cavity (15), a cathode (12) mounted in the cavity wall, and a momentum analyzer system (17). The resonant microwave cavity, when supplied with microwave power, supports an electromagnetic field having a high-gradient electric component directed along an acceleration axis. The cavity is formed with an exit aperture (32) at a location relative to the cathode such that emitted electrons are accelerated along the axis and pass through the exit aperture. The cavity length is chosen to allow the microwave field within the cavity volume to accelerate the electrons to an energy of about 0.5-1.0 MeV prior to the electrons' passing through the aperture. Bunching is provided by the momentum analyzer. An electron emerging from the cavity has an energy determined by the phase of the microwave field at the time of that electron's emission. Those electrons having energies corresponding to the desired initial phase value are permitted to pass through the momentum analyzer, thereby forming a prebunched electron beam for injection into a linear accelerator.
