Patent DE-3642135-C1 (DE)
Title: Filter insert
Inventor: BAUMANN DIETER
IPC: F02M35/024
Filed: 1986-12-10
Granted: 1988-02-18
Abstract: Filter inserts having a folded filter medium strip are generally held in a plastic frame. In the production of the filter, influx of the plastic mass into the spaces between the folds must be restricted to a desired extent. In the case of known filter inserts, this takes place at the expense of the usable filter area and/or stability; moreover, they require a relatively complicated mould. The novel filter insert is to have as large as possible a usable filter area, to be stable and to be simple to produce. The novel filter insert has a thin sealing material strip (41, 42) delimiting the plastic frame (3) from the two open filter medium narrow sides (23, 24), the height of which strip is about half to three quarters the height of the adjacent narrow side (23, 24) of the folded filter medium strip (2) and which sealing material strip is arranged in the lower part of the filter medium strip (2) in the frame (3) moulding operation. The novel insert is mechanically stable, simple to produce and offers a large filter surface area with predetermined exterior dimensions. The filter insert is suitable in particular for air filters of internal combustion engines. <IMAGE>

Patent DE-3805954-C1 (DE)
IPC: H01L39/12
Filed: 1988-02-25
Granted: 1989-09-28
Abstract: Polycrystalline high-Tc superconductors of general formula MmEeROx, composed of essentially crystallographically oriented granules, in which M is at least a trivalent element, such as a lanthanide, E is at least a divalent element, such as an alkaline earth element, R is at least a transition metal, such as Cu, and x is the oxygen content, are prepared by substituting some of the alkaline earth element by a foreign element, preferably an alkaline element, the content of which, after reaction sintering and sintering, will no longer lie in the parts per million to parts per thousand range and which will bring about a change of orientation. The resulting material has a slightly lower E and possibly M content and the same transition temperature, and has a substantially greater stability to external influences than corresponding known materials. A subsequent treatment in a current of air or oxygen is not necessary. Monocrystals of relatively large dimensions can also be prepared in the same way.

Patent DE-4033907-C1 (DE)
IPC: A47C1/024
Filed: 1990-10-25
Granted: 1992-05-07
Abstract: The invention concerns a chair with a rigid seat carrier (2), and with a back (6) mounted so that it can pivot on a substantially horizontal support arm (5) fitted underneath the seat on a bearing about which it can rotate. A spring (13) is fitted which acts to keep the chair back in the upright position, the return force exerted by the spring increasing progressively as the seat back moves further out of position. The invention achieves this by virtue of the fact that an articulated lever (8) with one arm (10) attached to the chair seat and the other (9) attached to the chair-back support arm is mounted, to be able to rotate, at a point remote from the point of bearing of the chair-back support arm onto the chair seat. The spring acts on the articulated lever at a point remote from the points of articulation of the articulated-lever arms to the chair seat and seat-back support arm and in a direction which counters the extension of the articulated lever.

Patent DE-4129948-C1 (DE)
IPC: E04D11/00
Filed: 1991-09-10
Granted: 1992-07-30
Abstract: In the case of known quadruple plate bearings, for height adjustment it is possible only with difficulty to reach and shift the spokes of the setting wheels of such a bearing, it being necessary either to insert a rod or the like through the gap between two plates or raise the plate to be levelled. In order to avoid raising the plate or shifting the setting wheel spokes by means of a rod inserted through a gap between two plates, the setting wheel is designed as a gear wheel (6) with which there meshes a second gear wheel (7), the shaft (19) of which has a receiving device for a setting key, which can be inserted through the gap (2b) between two plates. By virtue of its convenient and quick height adjustability, the plate bearing is suitable for supporting plate surfacings of terraces and similar areas covered with plates. <IMAGE>

Patent DE-4219653-C1 (DE)
Inventor: BOHN DIETER DIPL ING
IPC: G05D23/24
Filed: 1992-06-16
Granted: 1993-10-21
Abstract: A room temperature regulating process with a load-adapted energy consumption is disclosed. The integration of all highly efficient external sources of heat and the optimization of the temperature gradients at the heating elements ensure a high comfort. For that purpose, a heat flow W1 from a heating water generator (6) which corresponds to the output signal (5) of a regulation amplifier (1) whose first input (2) receives the set value signal tiset for the room temperature, is led into the room to be heated by a heating element (8). A signal which corresponds to the difference between the mean values of the flow temperature tV and the return temperature tR and to the difference between the flow temperature tV and the return temperature tR amplified by an adjustable proportionality factor d is fed back to the second input (3) of the regulation amplifier (1), which acts as a comparative input.
Patent DE-4308853-C1 (DE)
Title: Marking of patterns on dough shapes, esp. bread rolls - the movement of the marking elements is interrupted or reduced for a period of 0.5 to 4 seconds during the marking process
Inventor: MALINDRETOS JANNIS DIPL ING
IPC: A21C11/12
Filed: 1993-03-19
Granted: 1994-04-21
Abstract: A number of dough shapes (2) are marked with a pattern in a procedure in which the pressure or cutting elements (6) are moved with an essentially constant speed. The novel feature is that movement of pressure/cutting elements is interrupted during operation, and this interruption lasts for longer period than that normally associated with reverse movement of marking elements. Also claimed is a device for carrying out this procedure, with a control unit (12) which controls the speed of the drive (11) which moves the marking elements. The interruption of movement may be in the form of a reduction of the speed of the elements to a lesser constant value, or the elements may be brought to a stop for a certain period of time, pref. between 0.5 and 4 seconds. The control allows the movement of the elements to be stopped for a selected time period (15) when the elements (6) are near the dough support plate (1), and in particular when they are engaged in the dough shapes (2). The mechanism consists of an eccentric operated by an electric motor controlled by switch and a timer. The switch may be in the form of a relay or an electronic switch. USE/ADVANTAGE - Used for marking, e.g. bread rolls with a pattern to improve their appearance and taste. Marking is successively performed independently of the baking process involved and of the natural variability of the dough, without the need for any adjustments of the marking procedure or of the mode of operation of the baking system.

Patent NL-1006100-C1 (NL)
Title: Treatment of liquids, e.g. manure, sewage or sea water
Inventor: WALTHIE PATRICK
IPC: C02F1/44
Filed: 1997-05-21
Granted: 1998-11-25
Abstract: An apparatus for treating liquids which are contaminated with solid, suspended or dissolved substances and emulsions, contains a microfiltration or ultrafiltration system provided with a ceramic filtration tube. This filtration system leads to an evaporation system for removing any remaining dissolved or emulsified substances by evaporating the liquid. Any inert gases present do not interfere with the treatment process and do not affect the quality of the water recovered. Evaporation is carried out at reduced pressure using mechanical vapour compression. The rotary speed of the circulation pump in the filtration system is regulated using a frequency converter, depending on the temperature and pressure in the system, the speed being reduced once a set temperature and/or pressure limit is reached. Removal of concentrate from the filtration system can be varied, the flow being controlled by a valve or pump system. Permeate from the filtration system is removed to a vacuum tank, the rate of removal being controlled by a pressure regulating system, or alternatively if this is not present the evaporation system can be constructed to make the filtration system operate at reduced pressure. The pressure-regulating system consists of a pressure valve that opens once a set pressure level has been reached on the filtrate side. A pump system such as a hose or membrane pump can be installed in the pressure-regulating system. Any pump installed is used to maintain a pressure difference between the pressurised and vacuum side. The treatment method carried out using this apparatus is also claimed.
