Patent DE-3724247-A1 (DE)
Inventor: HOFMANN HANS-JOACHIM DIPL ING
IPC: B04B11/04
Filed: 1987-07-22
Abstract: A device of this kind comprises a sedimentation container (94) which is arranged laterally below a separation centrifuge and is placed tightly against a connection plate (98) of the centrifuge housing (50). In order to exchange it, the sedimentation container (94) is forcibly guided on a right-angled path. For this purpose, it runs with laterally horizontal guide ribs in a bracket (182) which itself is vertically forcibly guided. The connection plate also bears a sediment level electromechanical sensor (134), the said sensor having a sensor plate (150) which drops in a damped manner under the effect of gravity against the collected sediment. In addition, the connection plate (98) bears a return pump (122) for pumping out clarified liquid located above the sediment. <IMAGE>

Filed: 1987-07-22
Abstract: The invention relates to a device for the laser treatment, in particular for radial keratotomy of the eye with a treatment laser whose focussed beam guides a scanning device over the eye region to be treated. For this, there is provided an axially displaceable lens group which is controlled by a control unit in the axial direction in a manner corresponding to the movement of the scanning device. This device can be subsequently fitted as an accessory to already existing surgical microscopes and guided into the beam path by pivoting.

Title: Assembly kit for storage heating stove
Inventor: WACHTER JOSEF
IPC: F24B1/04
Filed: 1987-12-14
Abstract: The invention relates to an assembly kit for a storage heating stove with complete combustion, having a combustion chamber and flues extending thereabove in levels. The individual design and construction of such basic stoves is very time-consuming and costly. By means of an assembly kit which is notable for a small number of different components and the simple manner in which it can be manually assembled, the costs can be kept low despite manifold design possibilities. Such an assembly kit consists of curved, straight or corner elements, depending on whether the stove is to have a round or square outline, and of a plurality of slabs which serve as floors for the combustion chamber or partitions between the individual levels of the flue-gas passage, or as upper closure cover. In order to cause the flue gases to circulate annularly in each level, each level has a core in the form of a tubular piece or the like, so that a circulation of the flue gases is forcibly produced, which must flow from the inlet opening of the one intermediate slab to the offset inlet opening of the next intermediate slab above. In addition, the time required for assembly of the assembly kit is reduced, since the joining together of the wall elements is substantially simplified by means of grooves and tongues formed on the contact faces to the neighbouring wall elements.

Abstract: In a process for the purification of sulphate-containing waste water (effluent), a solution of calcium chloride is added to the waste water having a pH of 1 to 6 in a mixing zone such that molar ratio of Ca<+><+> to S04<+><+> of (0.5 to 3):1 is established in the mixing zone . The discharge from the mixing zone is led into a well-agitated holding zone while the overflow from the holding zone is transferred to a thickening zone, from which the separated thick sludge is fed to a filtrate zone. A plant for carrying out the process consists of a neutralisation unit which is constructed of a neutralisation tank, a crystalliser and a sedimentation tank. A waste water feed pipe (1) is connected to a mixing section (2) into which a feed pipe (3) for a solution containing ionogenous calcium enters tangentially. The mixing section (2) is connected flow-wise to the lower region of at least one holding tank (5). The holding tank (5) is connected flow-wise to a thickener (12), from the bottom outlet of which a sludge pipe (13) leads to a filtration unit. Finally, a pipe (14) is provided which leads from the upper region of the thickener (12) to the neutralisation tank. <IMAGE>

Title: Polyamide and film comprising at least one monomolecular layer of a polyamide
Inventor: CHERDRON HARALD PROF DR
IPC: C08G69/26
Filed: 1988-09-07
Abstract: A polyamide of the formula <IMAGE> in which Y is a divalent radical, X is a divalent radical having a chain of at least two carbon atoms, A and B, independently of one another, are H or C1-C26-alkyl, and n is an integer greater than 4, contains at least one C6-C16-alkyl group per recurring unit. X and/or Y contain at least one CH2 group in the chain. The polyamide is prepared by reacting a diamine of the formula NHA-X-NHB with approximately equimolar amounts of an activated derivative of a dicarboxylic acid COOH-Y-COOH. The polyamide is suitable for the preparation of ordered monomolecular LB films on a carrier. To this end, it is dissolved in a volatile, organic, water-immiscible solvent, the solution is spread on the water/air interface, and the layer is compressed after evaporation of the solvent and transferred onto a solid layer carrier by the Langmuir-Blodgett technique.

IPC: E05F15/16
Filed: 1988-09-08
Abstract: Actuating device for movable parts for closing apertures in vehicles, with a reversible direct-current drive motor, with a pole-reversing actuating switch located in the motor circuit and intended for applying a direct voltage to the motor circuit with a polarity corresponding to the desired direction of rotation of the motor, with a relay having a switch contact located in the motor circuit in series with the pole-reversing actuating switch, and with a position-recognition stage, connected to the relay control circuit, for actuating the relay in a reference position of the movable part for the purpose of stopping the drive motor by opening the switch contact. The relay is a direct-current relay which closes and opens the switch contact respectively when a first and a second voltage level is applied to its control circuit. An electronic relay-actuating stage having a storage behaviour is connected to the relay control circuit. The relay-actuating stage is maintained in the set state in dependence on the position of the movable part, with the pole-reversing actuating switch closed, until the movable part has left the reference position. <IMAGE>

Title: Gripping device
Inventor: MUELLER ARNOLD
IPC: B25J15/02
Filed: 1988-10-26
Abstract: A gripping device for manipulators has two grippers which are movable relative to one another and between which, in the gripping position, an object can be picked up and retained. Both grippers are jointly actuated via a drive means. They are each held on a slide which is translationally displaceable in the housing along a rectilinear guideway, each slide having a spindle drive with spindle and spindle nut. A single electric three-phase a.c. motor, common to all gripper pairs, which is aligned with the rotor axis transversely to the mutually coaxial spindles of the gripper pair is used for the drive. Located in the crossing region is an angular gearing in the form of a bevel gearing, via which both slides are jointly driven. The drive is continuously adjustable with respect to rotational speed and torque via a measurement transducer and a control unit and permits a very precisely controllable clamping force in respect of the object to be grasped between the grippers.
