Abstract: A multicolor electrophotography apparatus for forming a color image on a rotatable photosensitive device (11) shaped cylindrically and arranged to hold on its circumferential surface an electrostatic image optically formed by an exposing device. The apparatus includes a plurality of developing devices (31,32,33,34) movably provided along the circumference of the photosensitive device (11) for developing a plurality of different-color toner images overlapping each other. Each of the developing devices (31,32,33,34) is selectively driven to take a developing position and a non-developing position, each of the developing devices (31,32,33,34) being closed to photosensitive device (11) up to the developing position and being separated therefrom up to the non-developing position. When the exposing device is in the non-operated state, at least one of the developing devices takes the developing position and the other developing devices take the non-developing positions.

Abstract: The process for isomerisation of n-butenes is carried out over solid-bed catalysts. In order to convert n-but-1-ene into but-2-ene, it is proposed to isomerise n-but-1-ene in the gas phase over a catalyst containing superacid fluorine compounds of elements from main group III, IV and/or V of the periodic table in the absence of hydrogen. In order to obtain high yields of but-2-ene, which upon alkylation using isobutane produces petrol components having high octane numbers, the use of an H2SiF6/Al2O3 catalyst has proven to be particularly suitable.

Abstract: Filter centrifuges for the separation of suspensions, the drum of which has a corotating syphon device according to DPS 22 60 461, have the disadvantage that the filtration-accelerating action of the syphon device is destroyed by gas intrusions into the collecting space under the filter medium. Until now, this gas could only be expelled after each charge by backwashing through the filter medium once the solid had been removed. 
<??>The object consists in providing an outlet which permits the expulsion during filtration of gases which have penetrated the syphon space. 
<??>This object is achieved by means of a non-return valve (18) radially arranged within the syphon device, preferably on the drum floor and connected to the collecting space (11) or by an additional syphon device (17, 19, 20, 21) acting as non-return valve. 
<??>This device can be used on discontinuously operating filter centrifuges with rotation syphoning according to DPS 22 60 461, the housing inner space of which is at ambient pressure or is fed with compressed gas for the purpose of further accelerating the filtration.

Abstract: For the improvement of the measurement accuracy in conveyor belt weight feeders, a process is proposed, in which firstly the rotational speed of the conveyor belt (1) is established directly and without slip and is then set in relation to the input reference drive speed or rotational speed. By this means, error influences, such as slip, temperature and load dependency, on the rotational speed can be determined reliably and corrected or eliminated. Even oblique running or lateral displacement as well as fluctuating dead weight of the conveyor belt (1) can be established and avoided or corrected.

Abstract: A reinforced composite gasketing material characterized by high strength and dimensional stability, excellent recovery and superior creep relaxation resistance properties and a process for producing such a gasketing material (22) are provided. The composite gasketing material (22) of the present invention is a multiple layer laminate of filled polytetrafluoroethylene (PTFE) and at least one ply of perforated stainless steel. The process of the present invention includes the steps of pressure sintering alternately layered sheets of a PTFE/filler blend (20) and stainless steel (24) by the application of a sequence of intervals of pressures and temperatures selected primarily according to the thickness desired in the finished material and then rapidly cooling the sintered composite under pressure. The resulting gasketing material (22) has the metal layer completely encapsulated by and bonded to the PTFE/filler material. The process of the present invention can be used with equal facility to produce gasketing material in sheet form from which individual gaskets can be cut or in the form of individually molded gaskets. One embodiment of the present invention provides a gasketing material characterized by high compressibility particularly suitable for use in glass-lined pipes.

Abstract: A tape transport for a leader block tape cartridge (10) has a threading mechanism including a threader pin (50) for engaging the leader block (16) and extracting it from the cartridge after it has been loaded into the transport adjacent a first end of a tape path. The threading mechanism pulls the leader block along the tape path pas a read/write head (52), and inserts the leader block into a take-up hub (60) adjacent a second end of the tape path during a threading operation. During a rewinding operation, the threading mechanism extracts the leader block from the take-up hub, pulls the leader block past the read/write head and inserts the leader block back into the cartridge. A first guide assembly (70, 42 a ) adjacent the first end of the tape path engages and guides the leader block to ensure proper insertion thereof back into the cartridge during the rewinding operation. A second guide assembly (72, 42 b ) adjacent the second end of the tape path engages and guides the leader block to ensure proper insertion thereof into the take-up hub during the threading operation. This accommodates the tolerance variations in the positions of the cartridge and take-up hub, and in the dimensions of the cartridge, leader block, take-up hub and threader pin which can otherwise lead to failures in the aromatic insertion of the leader block into the cartridge and/or take-up hub.
