An apparatus for partial dehydration of a sludge in the centrifugal field of a centrifuge wherein the residual moisture of the sludge is substantially reduced with a comparatively low compression of the sludge, and the non-effective cone length of the centrifuge is reduced without shortening the sludge dwell time. The invention includes an arrangement of agitator elements within the centrifugal dr...

PURPOSE:To facilitate lever action of speed change gear and clutch by interlocking operational rods for operating a speed change gear and a clutch through single lever. CONSTITUTION:A speed change.clutch lever 149 will hold a clutch rod 126 at the solid line position in a groove 152 of an operating board 150 to disconnect between a friction wheels 54 and 56. When positioning the lever 14 in a rece...

PURPOSE:To perform abrupt travel/stop operation without changing step of pedal even under deflock operation by interlocking a differential device with the pedal. CONSTITUTION:A cam 28 for pressure operating a shift fork 26 through stepping under initial non-travel/stop operation range (a) and following travel/stop operation range (b) to the deflock side is fitted over a rotary support 12A rotatabl...

An open- or closed-loop control system is proposed, having at least one measuring transducer, an evaluation circuit connected with this transducer and at least one magnetic valve, which is incorporated in a hydraulic or pneumatic actuation system. The evaluation circuit and the electromagnet of the magnetic valve to be triggered by it are accommodated in a common housing; the valve or valves are a...

Halides of Si and Ti, B, P, or Ge and oxygen or steam are introduced into a reaction vessel and heated in a vapor phase to form fine glass particles by oxidation or hydrolysis. The fine glass particles are deposited on a substrate. The deposited fine glass particles are heated and vitrified into a transparent glass layer, which is etched to form a core having a desired pattern by a reactive sputte...

A moving magnet elctromagnet for a servo-control device e.g. in a printer comprises a fixed winding 12 on a core 11 attached to a support 10. A cylindrical magnet support 14 is resiliently mounted by a spring wire for coaxial movement over the coil 12. Four strip magnets 17 extend along the four sides of a square opening in the carrier 14 and are magnetised across their thickness with north poles ...

A system for preparing and splicing two yarn ends has preparation nozzles in a turbulence chamber adjacent the end faces of a casing. The preparation nozzles improve the quality of the splicing by thinning the yarn ends. Compressed air or a partial vacuum can operate the preparation nozzles. With preparation of the yarn ends in the turbulence chamber for the splicing, the expenditure for a prepara...

A solenoid valve (11) consists of a permanent magnet (13), a coil (22) and a valve member (29) which opens towards the low pressure side. The coil (22) and the permanent magnet (13) are so arranged that the magnetic lines of force either extend in opposite senses or in the same sense. The construction provided by the invention enables the magnetic valve (11) to be used for supply of fuel to otto a...

In a device for determining the density distribution on a straight line by means of a narrow penetrating beam, the measuring accuracy for the center of an object to be examined is increased in that the primary beam is not only displaced perpendicularly to its direction, but is also rotated around a point in this center. To this end, a radiation source and a detector device are mounted on a support...

A rotary plate-shape material cutting apparatus is disclosed. The apparatus comprises a pair of hollow knife cylinders, each provided with a knife on the circumferential surface and adapted to rotate in mutually opposite directions, shafts piercing the hollow portion of the knife cylinders and having both ends thereof supported by frames, bearings positioned at both ends of the knife cylinders and...

The binding has an elastic band (1) releasably attached to the ski at the rear of the centre of gravity. It works in conjunction with the boot (5) of the skier, directly adjacent to its opening. The toe of the ski boot engages a stop on the front of the ski.
