Abstract: A wrapping machine, particularly for wrapping cigarette packets in wrapper film, includes a series of endless band conveyors (148, 152, 156, 166, 170) carrying pushers (150, 154, 158, 172) for moving successive packets (191) along a straight wrapping line. One of the pushers (158) is heated to seal a wrapper seam. Opposed heated band conveyors (166) simultaneously seal end folds of the wrapper. Packets are gripped between opposed conveyors (145, 148) immediately after intercepting a wrapper (100). Partially-wrapped packets are arranged to slide relative to surfaces (149, 153, 157, 180) to attain wrap tightness. Successive conveyors (e.g. 156, 170) are independently driven to allow phasing of the conveyors to vary the position at which packets are transferred between them.

Abstract: Dans les embrayages à friction connus dont les disques, déplaçables axialement et reliés en alternance de manière solidaire en rotation à une entrée d'embrayage et à une sortie d'embrayage qui lui est concentrique, sont amenés en contact de friction aux fins d'accouplement par une plaque de pression axialement déplaçable ainsi que par deux segments de pression disposés en ligne par rapport aux disques et pourvus respectivement de régions de surface correspondantes inclinées axialement en forme de rampe, la course utile d'embrayage est fonction du nombre total des disques; elle s'allonge en conséquence en cas d'usure des garnitures de friction. Ce nouvel embrayage à friction présente une faible course utile largement indépendante de l'usure, et cela indépendamment du nombre total des disques. Les deux segments de pression (6, 7) sont agencés entre la plaque de pression (5) et les disques proprement dits (3, 4).

Abstract: 2.1 Liquid level sensors for fuel containers which have a pivot axle constructed on a housing part of a mounting flange, on which pivot axle pivotable angle transmitter arms are aranged, are already known. Due to the rigid connection of the pivot axle to the fuel container via the flange attached thereto, the deformations or manufacturing tolerances of the fuel container have a direct effect on the pivot axle and thus on the measuring accuracy of the liquid level sensor. The novel liquid level sensor is intended to permit the liquid level to be measured accurately and independently of the deformation or inaccuracy of the fuel container. 2.2 This is achieved in that the transmitter unit (3) of the liquid level sensor (1) is arranged fixed in position between the tank flange (2) and the fuel container floor, the bearing of the transmitter unit (3) being constructed at its upper end as a pivot bearing around which a housing (4) which surrounds the transmitter unit (3) can be pivoted and the lower end of the transmitter unit (3) being centred on the fuel container floor by means of a floor support (15). 2.3 The liquid level sensor (1) can be used in particular in fuel containers (23) of motor vehicles. <IMAGE>

Abstract: Flexible fabric or plastics sheeting (24) is secured to a support structure by a fastening means comprising three elongated members, namely a body (10), a resilient, expandable gripper (12) and an expander (14). The body (10) has a channel (16) therealong opening  via  a restricted mouth (20) to a surface of the body (10); the sheeting to be secured is tucked into the channel followed by the gripper (12).
