A shredding apparatus of the type comprising three or more rotating shredder rollers with parallel axes, each roller formed by a plurality of toothed discs with spaces between them, the discs of cooperating rollers being offset so that each can enter the spaces between discs of adjacent rollers, some of said rollers cooperating with curved grid sectors (26, 28) that are coaxial with the rollers th...

The utility model relates to a solar water heater core with an elastic sealing structure, which comprises a core barrel and a core cap. The overlapping edges of the core barrel are in notch engagement, and a pinched elastic sealing body which is generally made of rubber plastic materials is arranged in the middle part of the core barrel. The core barrel and the core cap are also in notch engagemen...

The shift quality of an automated mechanical transmission (10) is improved and transmission wear is reduced by controlling the armature current of the motor driving the transmission shifting mechanism (22). The current is monitored by a microcontroller (16) to determine if the shifting mechanism has encountered a snag or has stalled during a shift operation. The microcontroller (16) is programmed ...

A planetary gear has two driven shafts (3, 4) which turn at different speeds of rotation. The speed of rotation of the second driven shaft (4) may be reduced or increased by a second stage of the gear whose input shaft (5) acts as a regulating shaft and has an adjustable speed of rotation. The difference between the speeds of rotation of both driven shafts (3, 4) depends only on the speed of rotat...

The tread loosening consists in gripping a zero-degree reinforcing cord which the top of the tyre must comprise in order to apply this method, and in pulling transversely on this cord until it is completely removed from the tyre. Thus, the tread is very easily separated from the carcass of the tyre.

The invention relates to the field of container straightening and aligning machines. More precisely, the invention relates to an improved positioning machine comprising a rotating hopper wherein containers (6) are bulk-loaded and in which there are pushers or lifters (3) which rotate solidly with the hopper and are vertically mobile between a lower, loading position and an upper, unloading, positi...

Tyre bead is made on a forming wheel (20) by attaching the end of a wire (2) to the wheel and rotating the wheel to wind a predetermined number of turns of wire around it, the winding initially being at a first tension level created by resisting winding with braking means at a first resistance level and subsequently at a second tension level created by resisting winding with the braking means at a...
