Certain relief parts (11, 13) of a tread (1) for a radial tyre, are provided at least with incisions (41, 42, 43) having, in cross-section, outlines in the form of forks, and at least two prongs (41B, 41C) extending from a single portion (41A), the number of incisions (41) on the relief part (12, 13) being multiplied by a factor of at least 1.5 from the depth (h1) of the two-pronged incision (41)....

A control system for a continuously variable transmission (Fig. 2a) for a motor vehicle has a hydraulic circuit (Fig. 2a,2b) supervised by a control unit (70) which adjusts the transmission ratio. To improve system response under transient conditions the speed at which transmission ratio is changed is reduced as difference between actual transmission ratio and desired transmission ratio increases....

1. A forced induction, coal-fired steam generator for a gas and steam turbine power plant with a gas turbine connected to its exhaust line, a waste heat steam generator connected downstream on the gas-side of the gas turbine and a steam turbine connected to the steam side of the waste heat steam generator, characterised in that the coal-fired steam generator (1) includes at least one sub-stoichiom...

Since an optical equipment is supported by a parallel linkage (25) and the balance of weight with respect to all directions such as vertical, horizontal and turning directions of the parallel linkage is maintained, the optical equipment (34) looks as if it would be floating in the air and thereby can be moved to any desired position with small strength, and hence the operation can be carried out m...

Since the focus of an optical equipment stays on the extension of a straight line connecting the two base ends of a parallel linkage (25) and the focus (f) of the medical optical equipment (34) remains fixed at a fixed position when the parallel linkage is transformed, the medical optical (34) equipment does not need to be focused even when the parallel linkage is operated, and thereby operating t...

A torque distribution deciding control unit (50) a planetary gear device (20) as a central differential and an oil hydraulic clutch (27) having opposed disks are provided on a motor vehicle. The clutch (27) is disposed between output members of the planetary gear device, whereby torque is transmitted to front and rear wheels (10, 14) at a distribution ration decided by the torque transmission of t...

An improved electromagnetic actuator assembly is described. The assembly comprises a magnetic circuit for defining radially directed flux both in an inward and outward direction, and a coil disposed in the flux paths and connect to receive a control signal so that a current can be applied in one direction through those portions of the coil disposed in the inward radially directed flux, and applied...

An adjustable X-ray examination apparatus (24, 26) comprises an auxiliary element (38), for example a weight or a gas spring, in order to compensate for forces generated during operation of drive mechanism formed by parallelogram arms (16, 18, 20, 22). The forces increase with the amount of excursion from a neutral position. The auxiliary element may be mounted and adjusted so that, for the whole ...

A method for the direct gaseous reduction of iron ore to sponge iron at an elevated temperature suitable for hot briquetting, wherein a hot reducing gas is circulated upwardly through a descending body of iron ore and a make-up reducing gas stream is added to the circulating gas stream.
