Abstract: ABSTRACT OF THE DISCLOSURE          A camper unit for use with a dump truck includes a front portion normally resting on the floor of the dump truck with a rear portion extending down behind the tail gate area, but terminating clear of the ground.  When it is desired to unload the camper, the dump truck body is elevated until the ground engaging means on the lower rear corners of the camper unit dig into the ground or frictionally engage the ground with part of the weight of the camper unit thereon.  The truck is then driven slowly forwardly with the camper unit remaining stationary.  Towards the front underside of the front portion of the camper unit, a hinged ground engaging support frame is mounted and when it clears the tail gate area of the truck body, it swings downwardly by gravity.  The elevation of the dump truck body is adjusted as it is moved forwardly so that the support frame engages the ground thereby supporting the camper unit upon the support frame at the front and upon the rear portion of the camper at the rear.  To load the camper, the dump truck body is elevated so that the floor engages un-der the front lower edge of the front portion of the camper and the truck is backed up towards the camper.  This lifts the front end of the camper whereupon the dump truck body position is adjusted as the truck is backed under the camper, hinging the support  frame rearwardly as it moves under the camper until the camper is fully loaded into the dump truck body.  Means are provided to detachably lock the camper into the dump truck body.

Abstract: ABSTRACT:       A tachometer system for supplying a control sig-nal which is indicative of positional and/or speed errors of a rotatable element.  The tachometer system comprises a tachometer on which marks are arranged in a closed track, which in cooperation with a detector produce n tacho-pulses per revolution of the tachometer,  The tacho-meter system furthermore comprises a memory devise with n locations, in which n correction signals are stored.  The correction signals are obtained by driving the tachometer with an accurately constant speed, then measuring the phase difference between the tacho-pulses and the reference signal, and storing the phase-error signals related to the consecutive tacho-pulses in separate locations of the memory device.  When the tachometer system is used in a servo control loop these correction signals are used to correct the phase-error signals then measure, yielding a correction in respect of the deviations in these phase-error signals owing to positional tolerances of the marks on the tachometer.

Abstract: ABSTRACT: "Cable winder".     The invention relates to an automatic cable winder for, for example, a vacuum cleaner, comprising a latching device for latching the drum so as to prevent reverse rotation, and a braking device so as to ensure that the cable is wound smoothly and uniformly. A braking device is known in which the brake blocks are pivotably mounted on a flange of the drum, which brake blocks move outwards under the influence of the centrifugal force when the cable is taken up, engage with a stationary housing part and provide a braking action as a result of friction. As the winding speed of the drum is comparative-ly low,large brake blocks are necessary in order to obtain a sufficient braking froce. It is proposed to mount the brake blocks on a separate disc and to drive said disc by the drum via a speed-increasing mechanism. The disc now rotates with a much higher speed, so that only small brake blocks are needed.
