Title: Steering axle for a motor vehicle
Inventor: BOER DIETER
IPC: B62D7/18
Filed: 1987-10-29
Abstract: The invention relates to a steering axle for a motor vehicle, in which a stub axle can be moved, by means of a steering arm attached fixedly to it, from an end position with a stop surface of a stop part made of steel until it lies against a stop surface of another stop part likewise made of steel.

Patent DE-3741302-A1 (DE)
Inventor: HEVELING JOSEF
IPC: C07C67/00
Filed: 1987-12-05
Abstract: A process for the preparation of a catalyst suitable for use in the oligomerization of lower olefins to hydrocarbons in the diesel fuel range includes contacting an amorphous, solid catalyst support having cation exchange capacity with transition metal cations to bring about cation exchange of cations on the support by the transition metal cations, to obtain a surface loading of cation exchanged transition metal cations on the surface of the support within the range from 0,04 to 3,8  mu mol transition metal/m<2>. Oligomerization involves contacting the catalyst with olefins at a temperature from 20 DEG C to 400 DEG C, under a pressure from 100 kPa to 14000 kPa. The support may be SiO2-Al2O3, SiO2-B2O3, SiO2-Ga2O3, ZrO2-Al2O3, TiO2-Al2O3, SiO2-Y2O3, SiO2-La2O3, TiO2-Cr2O3, or TiO2-Fe2O3. The metal is preferably Ni, Ru, Co, Rh or Pd.

Title: Brake master cylinder with return movement arrest for the brake master piston
Inventor: WUPPER HANS
IPC: B60T8/44
Filed: 1988-04-22
Abstract: The invention relates to a brake master cylinder (1) with return movement arrest for the brake master piston (2) with control valve (11) which, in the event of brake pressure control, controls the flow of pressure medium between a hydraulic pump (31) and a pressure medium reservoir (23), comprises the valve seat (13), valve closing (11', 11'') and valve actuating elements (15), according to the main patent, application P 6273a. The object of the invention is to create a brake pressure control device, in which the brake pedal in antilock control mode is not returned into the brake release position. The intention is to reduce vibrations on the brake pedal during antilock control. The object is achieved in that the position of the valve closing elements (11', 11'') and the valve seat elements (13) relative to the valve actuating elements (15) of the control valve (11) can be adjusted due to the facility for positioning of the said elements (11', 11'', 13, 15). <IMAGE>
Patent DE-3814361-A1 (DE)
Title: Process for an improved alkaline oxidation
Inventor: RUITER ERNEST DE DR
IPC: C07D217/24
Filed: 1988-04-28
Abstract: Using anhydrous KOH some very specific oxidations of organic substances can be carried out. In this process the high melting point of the KOH has a very disadvantageous effect, because reactions in which at least one phase is solid are difficult to control. By addition of NaOH to the KOH its melting point can be reduced by about 180@C so that the reaction can now be carried out using a melt. The principle can be applied to batchwise and continuous processes. Isoquinolines e.g. can be converted to isocarbostyril in almost 100% yield.

Title: Spinning head
Inventor: LENK ERICH DR ING
IPC: D01D4/08
Filed: 1988-05-27
Abstract: In a spinning head, the parts belonging to the nozzle assembly are located in a nozzle pot (10). The nozzle pot (10) possesses, in its orifice, an internal thread, by means of which the nozzle pot can be screwed to a connecting plug. In order to prevent the nozzle pot from coming loose, a rotation safeguard is provided. For this purpose, the piston (18) serving for sealing is straight-guided in the nozzle pot and has a stop (25) which cooperates with a counterstop (27) of the plug. The stop engages into the counterstop only when the piston comes into sealing bearing contact with the connecting plug under operating pressure. <IMAGE>

Title: Encapsulated switch disconnector arrangement
Inventor: DIRKS ROLF
IPC: H01H33/10
Filed: 1988-06-16
Abstract: Encapsulated switch disconnector arrangements are increasingly used in medium-voltage switching installations. The reason for this is that they occupy a smaller amount of space than large-volume, air-insulated switching cells. The object now exists of accommodating all the important parts in a single, encapsulated housing, of further reducing the number of parts and of reducing the cost for the arc extinguishing device, with the same performance capability as the previous devices. The invention specifies an encapsulated switch disconnector arrangement in the case of which the moving contact piece is constructed as a double disconnecting blade (isolating blade) 1 and can be switched into three positions, and the extinguishing device consists of arc splitters 4 which are arranged in overlapping layers parallel to a busbar 12 (which is laid in the interior of the housing 9) in such a manner that the arc which is produced during the switching-off movement of the double isolating blade is bounded by a cohesive cooling surface. Such an encapsulated switch disconnector arrangement can be used in a plurality of configurations and for the R, Y and B phases in an encapsulated housing 9 which is filled with sulphurhexafluoride (SF6), it preferably being possible to use such a switching installation in mains power supply distribution stations. <IMAGE>

Title: Covering element for valley gutters
Inventor: KNOCHE ALFONS
IPC: E04D13/04
Filed: 1988-08-18
Abstract: The invention relates to a covering element for valley gutters, which comprises a substantially rigid, extruded, profiled web of plastic. To form such a covering element in such a way that it has the advantages of the known covering elements produced from unplasticised PVC, but at the same time does not present any problems in adaptation to different roof valley angles, it is proposed according to the invention that the web of plastic (1) should have over the cross-sectional width regions (2, 3, 4) of different hardness and flexibility, produced by means of coextrusion of differently curing moulding compounds, in such a way that it is soft in a narrow central region (4) around the longitudinal centre line and hard in the adjacent side regions (2 and 3). <IMAGE>

Filed: 1988-08-26
Abstract: In a flowmeter 101 working on the Coriolis principle, measuring-tube bight portions 111, 112 are excited into oscillation at the n<th> natural frequency. The bight portions are so arranged that their (n + 1)<th> natural frequency lies in the range of 0.7 fn to 1.5 fn but outside of resonance caused by the first natural frequency. In particular, the length of the measuring-tube bight portions 111, 112 can be at least 6 times their height. In that way the sensitivity of the flowmeter can be improved. A plurality of exciters and sensors are positioned along the tube R, which is of continuous construction.   <IMAGE>

Title: Conductor bushing in a vacuum container
Inventor: STRAEMKE SIEGFRIED DR ING
IPC: H01B17/26
Filed: 1989-04-05
Abstract: If a part (11) at a specific electrical potential is intended to be located in a vacuum container, it is necessary to pass an electrical conductor through the wall of said vacuum container (10). An insulating body (14) must be mounted in the wall (10) for this purpose. If physical or chemical processes take place in the container which lead to the separation (precipitation) of conductive material, there is a risk of the insulating bodies (14) in the interior of the container being coated and of the conductive coating forming a link between the conductor (13) and the container (10). In order to avoid material deposits on the insulating body (14), a gas flow is produced which flows along wall parts of the insulating body.

Patent DE-3924553-A1 (DE)
Inventor: WIESEMES JOHANNES DR
IPC: G21C19/317
Filed: 1989-07-25
Abstract: An improved device for eliminating combustible gaseous mixtures permits explosive, externally controllable combustion of the gaseous mixture, over the entire concentration range in which an explosion can occur, in partial volumes of the gas chamber separated by grids. Without the improved device, in certain concentration ranges continuous combustion in flame form occurs on inner grid surfaces as long as combustible gaseous mixture is present. Influencing this continuous combustion from the outside would be relatively expensive. It is easier to influence the expansion of the explosion wave front in partial volumes by means of incorporated elements and/or closed walls so that only explosive combustion occurs in partial volumes each of which promotes fresh combustion in partial volumes. This allows the combustion to be controlled from the outside.
