The invention concerns a method in the reeling of a web, wherein the web (W) is reeled by the intermediate of a first roll (11) onto a second roll (12), whereby, when the second roll (12) has reached the desired diameter size, new reeling is started from said second roll (12) of desired size onto a new second roll (10). After the first-mentioned second roll (12) has reached the desired diameter si...

A current-conducting backing 1 (Pb) is subjected to electrochemical treatment to produce an active material layer 6 (pbO2), a pressure of 0.005 to 6.5 Mpa being applied to the layer 6 during the course of active material formation by a layer of corrosion-resistant porous material 8. The treatment is carried out until the layer 6 reaches a thickness of 0.3 to 5 mm. The layer 8 may be resiliently de...

The invention relates to a process for melting thermoplastics by bringing the thermoplastics into contact with the hot vapour of a perfluorinated organic compound, the vapour having at least the temperature necessary to melt the thermoplastic used.

In a sheet feeder for sheet-processing machines, in particular sheet-fed printing machines, having a pile table (2) for receiving a main pile (4), which pile table (2) can be raised and/or lowered by means of a main hoist (3), and having a nonstop device with at least one, preferably two, supporting rack(s) (13) for receiving a residual pile (4a) from the pile table (2), on which subsequently ther...

A granular product is described which comprises sodium silicate and its water of crystallisation with a specific weight of from 0.5 to 1.2 and which is completely soluble in water at ambient temperature.

The invention relates to new pyrazolylpyrazoles of general formula I in which R<1>, R<2>, R<3>, R<4> and R<5> have the meanings given in the description, processes for their preparation as well as intermediates, and their use as herbicides.

The exercising machine has support legs (12, 112), a pair of support members (16, 116) and one or more resistance elements (22) in the form of elastic bands. The legs (12, 112) and support members (16, 116) are pivotally interconnected. The nature of the pivotal interconnection is such that the legs (12, 112) and support members (16, 116) can assume operative and inoperative states. In the operati...

In a sheet delivery for sheet-processing machines, in particular sheet-fed printing machines, having a main pile receiving device (4) which can be operated by a main pile hoist (5) which can be cycled during normal delivery operation by a level switch (7) and a nonstop device which can be activated to carry out a pile exchange and has an auxiliary pile receiving device on which there can be receiv...

A battery element useful as at least a portion of the positive plates of a lead-acid battery comprises an acid resistant glass substrate coated with electrically conductive doped tin oxide. This battery element may also be used in the bipolar plates of a lead-acid battery.

The system provided in a vehicle includes a detector (1a, 1b) for detecting a speed of a drive wheel, a speed of a non-drive wheel, and a speed of a vehicle. An antiskid control and/or a brake traction control (4, 18) is provided for detecting a deviation of the wheel speed from the vehicle speed. When the speed of the wheel deviates from the speed of the vehicle, a wheel speed control (18) is ope...

To secure a band (28) transported by a conveyor (29) to the circumference of a drum (1), head and tailpieces of the band (28) are grasped, the band (28) is transported by the conveyor (29) until the headpiece arrives at a desired head position, and the band (28) is then transported further and the drum (1) rotated. At the same time as the headpiece secured to the drum (1) arrives at a desired angu...

A wheel speed control apparatus for controlling a braking force and/or a driving force to be transmitted to wheels for maintaining the difference between the peripheral speed of each of the wheels and a vehicle running speed or an inferred value thereof at such position of the wheels at a value approximating the optimum value. The apparatus comprises a normal control for detecting and controlling ...

In the four-wheel-drive motor vehicle of transversely-disposed type, a front differential and a center differential are arranged coaxially on the axle line of front wheels, and an engine and a transmission are disposed transversely to the vehicle body in the rear of these differentials. This arrangement can relieve one-sided action of the vehicle body weight on the front wheels.
