Sheets gripped at 7 by their front edges are transported under deceleration until their release above stack 4, with gripper carriages 6 being guided, at least over a partial section 9a of the sheet-transport path 9, independently of endlessly revolving conveying chains 5. The gripper carriages 6 are, over the partial section 9a, released from the conveying chains 5, are transported at a reduced ra...

An oil pump driving device drives an oil pump combined with a transmission coupled to an engine for supplying working oil to lubricate the transmission and enable the transmission to make gear shifts. The transmission includes a first power transmitting mechanism for connecting the output shaft of an electric motor to the drive shaft of the oil pump, and a second power transmitting path for connec...

A coupling and holding unit for roving packages or tubes and features a hollow body (1), one end (2,3) of which is coupled to a spinning machine while the other end can be coupled to a wind up package or tube (T). An activator is located in the hollow body (1) and can be shifted in it. It can be connected to grippers or tongues (11,36), the ends of which can come out through openings (10,34) in th...

A solenoid valve designed as pilot valve for safety valve has a control poppet (16) that normally rests against the valve seat (18) under the action of spring force. The poppet is fixed to the valve armature (12) and this is surrounded by a pair of coils (20, 22). The valve is opened by energising both coils. Once open the position can be maintained open by having only one (20) of the coils energi...

Absorption mat lead-acid batteries poorly dissipate heat from the internal components of the battery (10) due to the air gap (35, 37) which exists between the plates (20) and the inner wall of the container (12). Improved thermal management of the battery (10) is achieved by filling the air gap (35, 37), an insulating gap, with a thermally conductive gel (40), such as a gel formed of fumed silica ...

There is provided a method for producing a resin-bonded magnet, which comprises steps of mixing a magnet element and microcapsules each of which contains at least one component of a thermally polymerizable resin composition as a binder component, mechanically breaking at least a part of the microcapsules during formation of a green compact comprising said resin composition and said magnet element ...

A crystallographic observation apparatus for the observation of behavior of crystals under pressure and for the measurement of the crystallization pressure and pressure of fusion of substances. The apparatus comprises a pressure chamber having a cavity and provided with a transparent observation window or windows, a pressurizing device for pressurizing the cavity of the pressure vessel, and small,...

The navigation system is for an independent vehicle (1) which is equipped with a lateral row of detectors (2). Magnetic beacons (3) are buried at intervals in the ground and create a localized field which in its turn creates a variable induced current in the detectors (2) depending on their position. Terminals consisting of magnets (151 to 155), whose number and polarity are chosen, form magnetic ...

A flexible and stretchable sheet material that is capable of being stretched to conform to a three-dimensional substrate to form a protective and decorative coating thereon is comprised of a thin flexible support having adhered thereto a protective and decorative layer such as a paint layer comprising a colorant incorporated in a film-forming binder. Both the support and the protective and decorat...

A tyre includes a tyre body 10 having a ground engageable wall 11 and two opposite side walls 12 extending from the ground engageable wall to be matched against an annular tyre frame 20, and a layer 30 of glutinous elastic material applied to the inner surface of the tyre body for being capable of immediately molecule-cohering if the tyre is pierced by a nail so as substantially to prevent the tyr...

A plastic mass is extruded from a nozzle, flowing axially along at least one helically twisted pin fixed to a central mandrel. The internal channels are formed without plastic deformation of the mass in the extrusion nozzle, in that the mass enters and flows along the nozzle (DM) substantially torsion free and either rotates the pin in accordance with its helical pitch or has a pin suspension driv...
