Title: Device for damping or preventing oscillations of a load conveying means, in particular of a lift
Inventor: SCHNEIDER KLAUS DIPL ING
IPC: B66B1/04
Filed: 1987-03-24
Abstract: If the load conveying means of a motor-driven hoist, in particular the cage (3) of a lift with a hydraulic drive motor that is operated in connection with an electrohydraulic drive system, is braked abruptly while underway when the electric power is interrupted - for example in an emergency stop or power outage - this causes oscillations of the cage (5) about the stopping point in the shaft reached at the emergency stop, due to the hydraulic drive motor (4). These oscillations are not only unpleasant to the people being transported, but can also lead to injuries. To prevent such oscillations, the use of a control device (1) is proposed, comprising mainly a measuring transducer (37), a pressure regulator (38), and a timing element (39), that is connected to the electrohydraulic control system of the lift. With the help of this device, the kinetic energy of the abruptly halted moving mass can be diverted in a controlled fashion, and thus dissipated. To do this, the dynamic excess pressure is registered, and a volume of oil with this excess pressure corresponding to the kinetic energy is discharged from the system. Either a separate two-way valve can be used, or, in an especially advantageous manner, the main lowering valve (15) belonging to the electrohydraulic lift control system, including its pilot valve (16) and the associated restrictor (17) or the like, can be utilised for this purpose. <IMAGE>

Filed: 1987-10-15
Abstract: A mounting rack is described for accommodating vertically arranged printed circuit boards which are fitted with electronic components. Said mounting rack is provided with forced ventilation which comprises vertically arranged fans, which are arranged in a rear wall of the mounting rack. The fans blow cooling air into a relatively large-volume pressurised area, which is connected to a distribution area underneath the printed circuit boards. The overpressure which builds up in the pressurised area and in the distributor is dissipated uniformly via the intermediate areas between the printed circuit boards, so that a surprisingly uniform air through-flow is produced between the printed circuit boards.
Patent DE-3737183-A1 (DE)
Title: Process for producing the frame of a terrestrial solar generator
Inventor: GOCHERMANN HANS DIPL ING
IPC: H02S20/00
Filed: 1987-11-03
Abstract: Process for producing the frame of a terrestrial solar generator, which frame has solar cells, which are connected in parallel and/or in series and are embedded in a support, and connection cables. The frame through which the connection cables led out of the support are guided is preferably made of plastic. So that, together with the production of the plastic frame, further measures can be carried out in one operation, the solar generator is inserted into a prefabricated frame mould into which the plastic is injected in liquid form. After the plastic is cured (polymerisation, crosslinking etc.), the solar generator, together with its frame, is removed from the frame mould. The plastic frame may be produced by a reaction injection moulding (RIM) process with a multicomponent polyurethane elastomer, by injection encapsulation. Components forming an integral structural unit and fulfilling predetermined functions may also be produced simultaneously with the plastic frame. <IMAGE>
Patent DE-3738270-A1 (DE)
Title: Wash-in container for the automatic metering of a detergent
Inventor: BUECKER HEINRICH
IPC: A47L15/44
Filed: 1987-11-11
Abstract: Between the connection 25 for feeding water from a drinking water line and an inlet orifice 14 of the wash-in container 1, there is provided a valve 16 which opens automatically when water is supplied. In this arrangement, the orifice 19 leading to the atmosphere prevents water being able to pass from the wash-in container into a drinking water line connected to the connection 25 when the wash-in container 1 is full, since suction is not possible because of the orifice 19 leading to the atmosphere. If the water supply is interrupted, the valve body 15 closes the inlet orifice 14 and thus permits the wash-in container to be subjected to subatmospheric pressure, which is necessary for sucking in the detergent during the next cleaning operation. By this means, back suction of non-drinking water into the drinking water line is impossible even if the wash-in container 1 is completely full. <IMAGE>

Patent DE-3800081-A1 (DE)
Title: Cleaning tool for the cutter head, cutter star and dough-enclosing ring of machines for plaiting pieces of dough
Inventor: HEPKE WILHELM
IPC: A21C5/00
Filed: 1988-01-05
Abstract: In all known machines for plaiting pieces of dough, the cutter star and the dough-enclosing ring have to be laboriously cleaned by hand. The cleaning tools according to the invention are (like the plaiting plates with the dough support) placed on the plaiting plate. The mechanical reciprocating movement of the cutter star together with the dough-enclosing ring permits the thin leaf springs which are situated on the bases of the cutter star cleaning plate in the tensioned condition to strip, using their outside edges, the dried-on residual pieces of dough from the cutter star chambers and the inside surfaces of the dough-enclosing ring. In order to remove the residual pieces of dough after insertion of the cutter star into the cutter head, the cutter head cleaning plate is placed on the plaiting plate and the residual pieces of dough remaining on the cutter head surface are removed by rotation through 360@. Use after cutting and plaiting of dark and white types of dough is therefore advantageous, as it saves times.
