Abstract: An apparatus for separating filter cake from an endless filter web, and method for using the same, for use in conjunction with a stacked plate filter system and filter web extractor. The filter cake and filter web separator apparatus includes a downwardly sloping support tray and a wedge-shaped plow blade having a resilient scrapper and suspended above, and generally parallel with, the support tray. As contaminated filter web exits a plate filter and is pulled through the separator apparatus by the filter web extractor, the resilient scrapper dislodges the filter cake from the filter web as the contaminated portion of filter web passes between the plow blade and the support plate and displaces the cake off the filter web where it falls into a suitable collection container. The filter web exits the apparatus from between the plow blade and support tray having substantially all of the filter cake removed from the filter web. In one embodiment of the invention, a suitable vacuum inlet can be disposed downstream of the plow blade to remove any residual moisture or particulate matter disposed on the filter web. Adjustment means are provided to allow height and inclination adjustment of the plow blade relative to the support tray and separation of the two components to facilitate threading of a filter web through the apparatus.

Abstract: Separator plants for sink material, in particular starch, and float material, in particular fats, for small waste water (effluent) quantities are to be made cheaper in terms of construction and simplified with respect to disposal. Adaptation to the volumetric flowrate existing on site is likewise to be readily possible. The novel separator plant which achieves this object is characterised in that all feed and outlet and discharge lines are conducted through the covers of the settling tanks and the covers themselves are easily detachably attached. In this manner modules are formed to which in particular standardised tanks of the desired size can be applied. Together with quick-release couplings for the external piping, rapid dismantling of the functional unit is also possible for disposing of the waste of the entire tanks. The plant can be installed complete on a small trailer and then brought to changing sites of use, such as mobile dishwashers. Waste disposal is likewise performed on the trailer.

Abstract: A scanning probe microscope in which the deflection of a cantilever (1, 104) caused by the proximity between a stylus (17, 109) and a sample (2) is detected, the relative distance between the sample and a probe at which the level of the deflection detection signal coincides with a reference level is subjected to servo control thereby to control the force exerted on the stylus to a constant level, and the relative positions of the sample and the probe are scanned to produce a three-dimensional image of the surface of the sample. In order to eliminate the error of servo control attributable to the deformation of the cantilever, the deflection detection signal is held with the cantilever set in free standing state, and the signal thus held is used to correct the level of the cantilever deflection detection signal. The servo control is effected by the detection signal thus corrected.

Abstract: The device (1) for drying and/or heating pourable material for asphalt production has a rotatable burning drum (11) which has holding structures for the material to be dried and rearranged. The burning drum (11) has, arranged coaxially with the burning drum axis (23b), a cylindrical, first pipe (25a) which surrounds the burner flame radially and axially and the inner wall of which is smooth and without internal structures in the flame region. As the casing of the inner pipe (25a) of the burning drum (11) is closed and the material is situated only on the outer casing thereof, i.e. the burner interior is separated from the material by the pipe wall, the burner interior with the burner flame is dust-free. As a result, the combustion process, which is low in harmful substances, is optimum and easy to control. By means of the smooth inner wall of the inner pipe (25a), sporadically introduced (sprayed-in) spray material from the pre-drum (9) or the transition (10) to the burning drum (11) is separated again through a coaxial slot at the pipe end. In addition, the combustion is not impaired by this small amount of spray material. <IMAGE>

Abstract: A low blocking packet distribution network (23) which is implemented in optics has both switch links and chute links, and the network nodes (e.g.30) include both a switching means (40) interconnecting successive stage switch links and a plurality of non-switching, chute connection means (50) interconnecting successive stage chute links. A network node can transfer a packet, being received on a switch link, to any selected one of the chute connection means of that node for transmission on a chute link. The network nodes are relatively simple and inexpensive because they store only the first few bits needed to route an ATM cell. The blocking probability is further reduced when the number of chutes per node is increased. The number of chutes may be based, for example, on the number of switch link inputs per node.
