Patent DE-4332799-A1 (DE)
Title: Process and apparatus for sludge dewatering
Inventor: RUMOCKI ANDRZEJ DR ING
IPC: C02F11/13
Filed: 1993-09-27
Abstract: In order to achieve a high dry matter content of sludges in their dewatering, drying and granulation, with relatively low expenditure in terms of apparatus and energy, it is proposed to prethicken the liquid sludge to give a thick matter by a dewatering centrifuge provided with a rotating basket shell. The residual water content is then virtually completely removed from the thick matter in a drying compartment which at least in part forms a structural unit with the centrifuge. The thick matter is ejected at the exit of the centrifuge at high velocity into the drying compartment in dispersed form as a particle mist. The transport of the thick matter particles and the heat transfer to the thick matter particles is controlled within the drying compartment by rotating vanes on the outer periphery of the basket shell of the centrifuge and if appropriate on an axial extension of the basket shell. <IMAGE>

Inventor: PETRICK DIETER
IPC: B65D6/16
Filed: 1993-12-11
Abstract: The invention relates to a packaging container, particularly for packaging, transporting, storing and stacking shoes, and to a method for its manufacture. The invention was based on the object of providing a packaging container which is simple and cost-effective to produce, is suitable as a reusable package, and requires only a small amount of space as an empty product, can be washed by machine and can be recycled in a cost-effective manner. As a solution, a packaging container is proposed, in which the bottom (13) of the receiving container (10) and the lid (9) consist of a flat or frame-like component (5, 8) of a stable, impact-resistant material. The sides (3) consist of a flexible material which can be folded together, the upper edge of the sides (3) being connected to a frame-like component (7) which acts in a reinforcing manner. On at least two mutually opposite sides (3), pivotable supporting elements (2) of a sturdy, rigid material are arranged on the frame-like component (7) connected to the upper edge of the sides (3). These supporting elements can be connected in a positive-locking manner to the frame-like component (7) and the bottom (13) in such a way that the sides (3) are tensioned and are secured against lateral displacement. The packaging container can be manufactured from a material, preferably polypropylene, by injection moulding. <IMAGE>

Title: Cartridge for pasty sealing compounds
Inventor: TOPIC ANTON
IPC: B65D83/00
Filed: 1994-02-04
Abstract: A cartridge for squeezing out pasty substances, e.g. those on a silicon basis, having a cylindrical body (21) is proposed, which is closed off at its front end by a base (37) in which a hollow nipple (23) is provided centrally. A plunger (29) arranged in a sliding manner in the body and made of a more flexible material compared to the body has an outwardly curved end wall (30) and a rib arrangement (32, 33) on the inner end face. A force acting on the plunger (29) displaces it forwards counter to the resistance of the pasty substance and brings about a spreading of the plunger (29) directed radially outwards for the sealing contact of a lateral circumferential surface (31) of the plunger against the inner wall of the cylindrical body (21). In this case, the shape of the plunger end face (30) and the shape of the inner surface (22) of the cartridge base including the hollow nipple (23) are matched to one another in such a way that the space between the plunger and the cartridge base is minimised in the position of the plunger (29) displaced completely towards the cartridge bottom (37). <IMAGE>

Title: Automobile radiator grille
Inventor: CHASE LEE A
IPC: B60R19/52
Filed: 1994-10-04
Abstract: The automobile radiator grille, for mounting on the bonnet cover (14), has a longitudinal segment (22) and a second spaced segment (24) forming a body section. At least one part of the body section is of a high impact resistant material with a given spring constant to allow a bending action on an external impact. A flange (20) extends from the first segment, to lie at the edge of the bonnet cover when the grille is mounted. Mountings (26) at the flange secure it to the bonnet cover to allow an elastic bending or swing movement on an external impact. Elastic components (32) at the second part of the body give a mounting with the bonnet cover to hold it in place, stabilise and stiffen it. The radiator grille is able to take an external impact without imposing a plastic distortion on the body part, the elastic components or the flange. The material to give a high impact resistance is a thermoplastic of a group of polycarbonate and acrylonitrile butadiene.
