Patent DE-4002347-A1 (DE)
Inventor: GOEDTNER WERNER DIPL ING
IPC: B21K27/04
Filed: 1990-01-26
Abstract: In known transfer devices, a linear driving movement for the gripper fingers has superimposed on it a swivelling movement of the gripper fingers, thereby making it possible to achieve a path of movement of the free ends of the gripper fingers which brings about a relatively rapid and wide opening of the gripper fingers and a corresponding withdrawal of the gripper from the tool concerned. The disadvantage here is the rigidly predetermined motional sequence of the gripper fingers. In order to achieve a motional sequence of the gripper fingers which is optimum for the individual requirements, the movement of the gripper fingers is controlled by cam tracks matched to the individual requirements and having track detectors. <IMAGE>

Inventor: HUTH HANS-ULLRICH DR
IPC: C07C271/20
Filed: 1990-02-27
Abstract: Ethylenically unsaturated, fluorine-containing urethane derivatives (see Formula I) whose urethane group is substituted on its carboxyl radical by a fluorinated organic radical and on its nitrogen atom by an unfluorinated, ethylenically unsaturated organic radical. Their preparation can be carried out by reacting ethylenically unsaturated, unfluorinated isocyanates with fluorinated organic hydroxyl compounds in bulk in the absence of water or advantageously in inert organic solvents or in ethylenically unsaturated monomers capable of polymerization which behave inertly under the reaction conditions, it being possible to obtain the urethane derivatives directly in liquid or highly viscous or waxy or solid or crystalline form. Urethane derivatives prepared according to the invention are usually readily to very readily soluble in standard nonaqueous, nonpolar inert organic solvents or in various monomers capable of copolymerization. They can be polymerized or copolymerized in a free-radical way and used to prepare polymers or copolymers.

A unit (28a) at the hood (28) holds and ejects the ejection plates (13). The conveyors (1, 4) travel round in the form of roundabouts with the tools (2) and hoods (6) round the circumference. The axes (3) of the conveyors to define the rotating edges are displaced w.r.t. each other at right angles to their axes, and the shot station (8) is placed radially to both rotary axes (3). Mixing hoppers (21) can be brought into a central position where the hoods (6) are in place to shoot the core shaping sand into the tool (2). A transfer station at the shot station (8) removes a basic mould lower box (11a) with the shaped section from the tool carrier (1) for the tools (2, 11, 12) and move back into the zone of the next open tool (2).

Title: Substrate body for activated sludge water-treatment tanks - composed of watertight closed-pored material, remains buoyant during operational periods
Inventor: HERTKORN WILHELM DIPL ING
IPC: C02F3/10
Filed: 1990-06-20
Abstract: Substrate material bodies whose vol. is less than 1 litre and whose specific gravity remains less than one during extended periods of operation are proposed for use in activated sludge water treatment tanks. Up to 40% of the surface area of bodies may project above the liq. surface in the tank, similar bodies of specific gravity down to 0.6 may also be used. As well as zones of open-pored material, the bodies have zones of material which is closed-pored, water tight and impervious to water-vapour diffusion. Buoyancy is provided by this second material. USE/ADVANTAGE - In activated-sludge tanks as a substrate for activated and unactivated sludge. The long-term buoyancy of the proposed substrate bodies avoids the problems experienced with currently used clarifier tanks, in which the substrate material tends to sink to the bottom of the tank when the tank is not being agitated or aerated. Operational problems are therefore avoided and the energy required for aeration is reduced.
