The invention relates to an arrangement for separating floating solid particles and/or solid fibers from solid-liquid mixtures by means of flotation. The arrangement comprises a main process container (1), into which the solid-liquid mixture to be separated is introduced by means of a supply line (2), to which the air bubbles required to implement the flotation process are supplied. In order to produce said air bubbles, a diffuser (5) is present according to the invention, into the inlet of which a part of the liquid discharged from the main process container (1) is conducted and the nozzle arrangement of which has an air supply opening. The outlet of the diffuser is connected to the supply line (2) of the main process container (1) in such a way that the air bubbles, which are produced in the diffuser (5) from the intake of air into the part of the already treated liquid that is conducted through the diffuser (5), are introduced into the supply flow of the solid-liquid mixture to be treated.

The invention relates to a chamber furnace for producing foam glass plates or molded bodies made of foam glass, said chamber furnace ensuring stable conditions for the production of foam glass plates or of molded bodies made of foam glass. A chamber furnace according to the invention for producing foam glass plates or molded bodies made of foam glass comprises a heat-transfer chamber in which individual heat-transfer units (2) lying one above the other horizontally are arranged, wherein one sub-chamber (1) is formed between every two adjacent heat-transfer units (2). Each of the sub-chambers (1) lying one above the other horizontally and formed in said way can be controlled in a separate heat-transfer zone. The individual sub-chambers (1) lying one above the other horizontally are designed either in the shape of compartments having partitions or not having partitions for accommodating pallets (6). The starting material (7) is foamed on said pallets (6). The arrangement of the heat-transfer units (2) ensures uniform heating and cooling of all pallets (6), wherein the heat-transfer units (2) have means (3, 4) that enable local heat supply and heat removal. Each sub-chamber (1) is controlled by heating or cooling in a separate heat-transfer zone.

The invention relates to an electromotive device for operating gas exchange valves on internal combustion engines, comprising a rotary actuator exerting forces on one or more valve stem ends of one or more gas exchange valves by means of a lever arrangement. The rotary actuator is a reluctance motor with a cylindrical iron rotor with permanent magnet segments of alternating magnetisation arranged on the circumference thereof. The average angular separation of the poles of the stator of the reluctance motor are approximately equal to the average angular separation of the permanent magnet segments on the rotor. The valve shaft ends operated by the lever arrangement preferably belong to gas exchange valves of a cylinder of an internal combustion engine the opening times of which do not coincide or belong to gas exchange valves on different cylinders. The reluctance motor preferably has a single-phase design. The device permits a valve clearance adjustment of the gas exchange valves by control of the actuator current and carrying out part lifts. The electromotive device for operating gas exchange valves is space-saving, low in energy consumption nd wear and self-retaining in certain working positions.

The invention relates to a method for shaping profiles of unidirectional fibre reinforced composite materials stabilised with a wound thread. The method is characterised in that a unidirectional fibre reinforced composite material web stabilised with a wound thread is shaped in a press mould with an open region and remains in the press mould until a form-stabilising hardening has occurred. The form-stabilising hardening is brought about by energetic radiation introduced into the shaped composite material web through the open region of the press mould. The composite material and the energetic radiation are matched such that the energetic radiation reaches deep into the composite material web and a form-stabilising hardening of the shaped composite material web occurs from within by polymerisation of the reactive resin. The particular advantage of the method is a comparatively rapid form-stabilising hardening of the shaped composite material web, whereupon high production speeds on production of unidirectional fibre reinforced composite material shaped pieces can be achieved.

The invention relates to a filter head plate for a filter for dedusting a gas, said filter head plate consisting of a top plate (1) and a lower plate (2) with an intermediate hollow space (3). At least one retaining device (4) for a filter element (5) is arranged in the filter head plate and consists of an outer retaining element (6) and an inner retaining element (7), the outer retaining element (6) being located in an opening of the filter head plate and having a through-opening for receiving the inner retaining element (7). A seal (8) is arranged in the outer retaining element (6) so as to surround the through-opening and can be inflated by pressurized gas. The inner retaining element (7) arranged on the upper end of a filter element (5) has a mating face (9) on the side facing the through-opening of the outer retaining element (6), on which mating face the inflatable seal (8) can be placed to rest. The pressurized gas for inflating the seal (8) is guided in the hollow space (3) of the filter head plate. A liquid conduit system (15) is arranged in the hollow space (3) of the filter head plate. Said conduit system can be used to guide a cleaning liquid to the nozzles (16) arranged on the filter head plate and projecting into the filter chamber.
