A period time required for a gear shift operation is measured from the time (T2) at which a prime motor (1) output speed (NE) starts decreasing to the (T3) time at which a psuedo speed ratio ( epsilon ) reaches a predetermined value. Based on the period of time measured, a line pressure is controlled during the period of time. Alternatively, a prime motor output torque is controlled during the per...

Moisture curable, foamable compositions that do not flow appreciably in the uncured state when applied on a vertical surface comprise an RTV elastomeric composition, a liquified blowing agent and finely divided silica in combination with either small diameter glass, metal or graphite fibers or carbon black. The RTV elastomeric composition comprises (1) at least one hydroxyl endblocked diorganosilo...

A resiliently flexible strip device mounts the armature of an electrically released brake for movement toward and away from the pole faces of the field shell, the armature either moving with pivotal motion or with linear motion. The resiliently flexible strip device may take the form of one or more leaf springs or may be one or more tongues molded integrally with the flange of a bobbin which forms...

Very finely granular metal powders are produced by atomizing a liquid jet of metal by means of a gas jet which, in addition to a continuous band of sound frequencies, contains at least one discrete sound frequency which is at least 5 decibel above the average intensity of this band, and which is generated in a rotationally symmetrical device by means of a nozzle (4) which has the shape of a hollow...

A fluidized bed reactor (1), suitable for recycling a fluidization gas containing in suspension particles of solid material, has a gas distributor (13) consisting of a double-coned body or of a series of concentric cones provided on their lateral surfaces with ribs or fins (18) forming gas inflow channels (19) shaped in such a way and with such an inclination as to allow the passage of the solid p...
