Patent DE-3503229-A1 (DE)
Title: Ventilator, in particular for vehicles
Inventor: JAECKEL HELMUT
IPC: F24F13/14
Filed: 1985-01-31

Patent DE-3505197-A1 (DE)
Title: Process for filtering solvents and apparatus for carrying out the process
Inventor: HAGER EBERHARD
IPC: B01D37/02
Filed: 1985-02-15
Abstract: The invention relates to a process for filtering liquid solvent batches in dry cleaning, and a rotary filter apparatus for carrying out the process. In known processes, filtration is carried out until the contamination has reached a degree requiring filter cleaning. Continuous filter monitoring is necessary for this. A high operating pressure and poor filter efficiency result prior to the necessity for filter cleaning. According to the invention, in a process in which, when the filter is contaminated, after shutting off the solvent inlet, the filter is rotated for cleaning and the detached dirt is removed, the constant inspection is avoided by rotating the filter to clean it after each individual solvent batch in a part of the batch retained in the filter apparatus and by completely flushing out the dirt detached during cleaning with the part of the batch prior to the next filtering operation. Since cleaning is carried out after each batch, complete contamination of the filter does not occur so that high filter efficiency and expediently low operating pressures are constantly present.

Title: Device for displaying and monitoring a system pressure
Inventor: DROIGK HUBERT
IPC: G01D1/12
Filed: 1985-06-04
Abstract: A device for displaying and monitoring a pressure prevailing in a system, in particular for mobile systems kept at constant pressure by pressure-maintaining elements, such as for example clamping devices on machining pallets of automatic machining systems, having a pressure-reducing unit installed in the pressure system, is intended to provide a solution by means of which the undershooting of a predetermined pressure is reported to the outside without this requiring a visual contact with the device on the part of the operator. This is achieved when the pressure-reducing unit (4) is fitted with a conversion device for converting the change (5) in length produced on the basis of the pressure changes in the pressure-decreasing unit into electronic pulses, with an electronic pressure display unit (6) having maximum/minimum setting (7), as well as with a signal transmitting unit (8-10) upon achievement of limiting pressure values. <IMAGE>

Title: Interference arrangement for testing wavefronts
Inventor: LANGENBECK PETER DR
IPC: G01J9/02
Filed: 1985-06-29
Abstract: Interference arrangements for testing wavefronts of coherent light beams are known which have a beam splitter, a plane reference surface and a prism. In order to construct such an arrangement so that it exhibits a high sensitivity with respect to the representation of an ideal wavefront starting as planar, the ideal state corresponding to optimum collimation, and in which, furthermore, there is the possibility to vary the sensitivity without a large technical outlay, the beam splitter is provided as the base face of the prism, which is arranged at a distance (H) which is between 5  mu m and 1 mm, and virtually parallel to the reference surface, the prism is adjusted with respect to the test light beams, which enter at one of its side faces and impinge at an angle of incidence onto the base surface at which they are partially reflected and through which they partially pass, the light beams passed being retroreflected at the reference surface into the prism and being brought into interference with the beams reflected at the prism base face, in such a way that the angle of incidence deviates slightly from the angle of total reflection, and the base face and the reference surface exhibit a deviation from planarity better than 1/5 of the wavelength of the test light beams referred to a distance of 5 centimetres in each direction.

Patent DE-3528225-A1 (DE)
Title: Turbocharger
Inventor: OKAZAKI TSUTOMU
IPC: F01D9/02
Filed: 1985-08-06
Abstract: The invention relates to a turbocharger for an internal combustion engine, which has a turbine of variable capacity. The turbine contains a worm section, the interior space of which is divided by a partition wall (5) into two worm chambers (4a, 4b). In the lower engine operating speed range, in which the speed of flow of the exhaust gases is low, these are led concentrated through only one worm chamber, in which the exhaust gases are forced to flow uniformly through the entire width of an inlet section of a turbine rotor (1). This increases the power output of the turbine, which then generates a high charging pressure and a high torque in the lower engine operating speed range. In the upper speed range of the internal combustion engine the exhaust gases are fed to both worm chambers. As a result, the turbocharger then has a very good charging pressure characteristic over a wide operating range of the internal combustion engine, which extends from the lower speed range through the middle speed range to the upper speed range. <IMAGE>

Title: Internal combustion engine with components tightly inserted in the cylinder head
Inventor: EMMERICH HUBERT
IPC: F02B19/14
Filed: 1985-12-12
Abstract: The invention relates to an internal combustion engine with components tightly inserted in the cylinder head, especially with a prechamber (4), which is connected by way of an injection duct (5) to the combustion chamber (6) of the internal combustion engine. An injection nozzle (7) opens into the prechamber, the prechamber being inserted into the cylinder head (1) with sealing compound (9) interposed between them. In practice it has emerged that the sealing compound decomposes due to very high temperatures and that leaks therefore occur. It is proposed according to the invention that the product of decomposition of a material decomposing in excess of a limit temperature be arranged as sealing compound. Since the product of decomposition exercises the sealing function, a reliable sealing is ensured, even in excess of high temperatures. <IMAGE>

Title: Strap carrier for furniture hinges
Inventor: BICKEL HELMUT
IPC: E05D5/02
Filed: 1986-07-21
Abstract: The invention relates to a strap carrier for furniture hinges which is produced from sheet metal and which consists of a base part of U-shaped cross-section, intended for screwing on, and of two supporting arms shaped in one piece out of the side legs of the base part and intended for mounting the joint straps. The aim of the invention is the simplified production and improved construction of such strap carriers, the starting point being the set object of providing a strap carrier which is shaped from sheet metal and can be produced simply in technological terms and which, along with increased bending strength, has a relatively enlarged projecting length of the supporting arms in relation to the base area of the base part. The solution for achieving this object is that the transverse web of the U-shaped base part constitutes the middle part of a respective overlapping of part of the two side legs on both sides and is designed to taper in a wedge-shaped manner from its rear end portion facing away from the two supporting arms towards its front portion facing the two supporting arms. The invention is used in the metalworking industry, in the production of fitting parts for the furniture industry. <IMAGE>

IPC: B01J35/04
Filed: 1986-09-19
Abstract: A ceramic catalyst carrier has a honeycombed structure which comprises a plurality of elongated parallel preferably square channels and thin, porous walls. The thickness of the walls is between 0.4 mm and 1.2 mm. The open cross-sectional area of the channels is greater than 80% of the total cross-section of the carrier body. Besides an intended low primary porosity, a secondary porosity is produced by an opening material. The pores of the secondary porosity which enlarge the active surface for the catalyst show a selected pore size distribution curve with negative skewness and a modal value ranging from 4,000 nm to 60,000 nm. The total true porosity amounts preferably between 50 and 70 Vol. % of the ceramic, whereby the ratio between total and secondary porosity is in the range of 1:1 to 6:1. By ceramic fibres the mechanical strength of the thin walls of the soft green clot and of the fired porous structure can be improved. According to the process the compounds are mixed to achieve a certain plasticity, aged and extruded to form a honeycombed structure which is thereupon dried and fired.
