Title: Synchronous swivel joint with outer and inner part - has ball tracks forming angle with coaxial axes, coinciding centre planes and radially projected centre lines onto axes
Inventor: WELSCHOF HANS-HEINRICH
IPC: F16D3/223
Filed: 1992-07-07
Abstract: The ball races (12) in the outer (11) and inner (13) part of the swivel joint are shaped so that, when the axes (A11-A13) are coaxial, and when the centre planes (E11-E13) of the inner and outer swivel joint parts coincide, the ball races on both sides of the centre planes in a radial projection onto the axes, together form an angle differing from 0 and which diminishes to their axial ends. With coaxial axes (A11-A13) and coinciding centre planes for the swivel joint outer and inner parts, the angles between the centre lines (M11,M13) of the tracks (12,14) change constantly over the axial length in a radial projection and the centre lines run mirror symmetrically to the axes. USE/ADVANTAGE - The forces exerted on the ball race are reduced and the race withstands greater stress under torque.

Inventor: FRIEDMANN SIEGFRIED
IPC: B01D53/30
Filed: 1992-08-21
Abstract: In catalytic redn. of NOx in engine exhaust gas by adding a reducing agent (I), the amt. of (I) added is calculated and controlled according to the amt. of NOx before and/or after redn. The amt. of (I) added is reduced if residual (I) is present after redn. ADVANTAGE - Redn. of NOx is maximised without residual (I) after redn. In an example, a control unit (2) sent signals to an i.c. engine (1) and (I) dosing unit (4), which injected (I) through a pipe (10) into the front exhaust pipe (5) leading to the catalyst (3) and back exhaust pipe (9). There was a NOx sensor (6) in the front exhaust pipe and a NOx sensor (7) and (I) sensor (8) in the back exhaust pipe, all sensors being connected to input terminals of the control unit.

Title: Method and apparatus for applying a temperature profile to metal billets intended for extrusion
Inventor: BISWAS AMIT KUMAR
IPC: C21D11/00
Filed: 1994-02-17
Abstract: The aim of the invention is, by influencing the temperature of an extrusion billet in a suitable manner, to apply to the said billet a temperature profile by means of which it is possible to optimize the extrusion process. This is done by heating (furnace 2) the metal extrusion billets (10a) to an extrusion temperature suitable for the metal, storing them at this temperature (holding chamber 3) subjecting them in a manner timed to coincide with the timing of the extrusion cycle to a quenching operation (chamber 5) divided into control zones (18), control in the zones (18) being exercised by modifying the quantity and/or temperature of the coolant and/or the duration of cooling in a manner such that, allowing for the thermal conductivity of the metal, the heat dissipation to the rest of the respective billet, to the billet holder and to the extrusion tools (punch, die) and the heating of the billet by the heat generated by deformation and (where relevant, i.e. in the case of direct extrusion) due to friction of the billet in the holder, the temperature distribution in the billet in the axial and the radial direction permits isothermal extrusion and an optimum extrusion rate.   <IMAGE>

Title: Method for implementing a filter edge or an optical thin-film bandpass filter, optical thin films and optical components therewith
Inventor: BUCHHOLZ JUERGEN
IPC: G02B5/20
Filed: 1994-03-24
Abstract: Proceeding from the need to filter out, in UV installations for therapy or cosmetics, the UV-B and UV-C spectral range on the one hand, the visible and near infrared spectral range on the other hand and thus to obtain at the optical output essentially only UV-A radiation, the filter edge is implemented in the direction of shorter wavelengths, that is to say essentially between the UV-B and the UV-A ranges by means of the absorption edge of a film material. It is recognised here that in the case of such a film material the absorption edge can be shifted to a desired spectral point as a result of the selection of the material composition. In a filter, whose filter edge is implemented in the direction of larger wavelengths by means of interference at thin films and in which the material, whose absorption edge is utilised, is simultaneously utilised as interference-film material, a shift (a, b) of the filter edge in the direction of shorter wavelengths results from the change in the composition of the mentioned material and thus of its absorption edge. <IMAGE>

Title: Passenger retention-belt system
Inventor: OMURA HIDEO
IPC: B60R21/0134
Filed: 1994-03-30
Abstract: A passenger retention-belt system is intended for use with a seat which is arranged in a vehicle. The system has a seat belt for retaining a passenger on the seat in a first retention position. The seat belt is driven by a first and a second preloading mechanism. The first preloading mechanism works in such a manner that it draws the seat belt from the first retention position into a second retention position, in which a first degree of tension is exerted on the seat belt in order thus to retain the passenger on the seat, while operation processes of the passenger are possible in order to avoid a vehicle collision when vehicle collision is feared. The second preloading mechanism works in such a manner that it draws the seat belt from the second retention position back into a third retention position, in which a second, greater extent of tension is exerted on the seat belt in order thus to retain the passenger on the seat against impacts which are caused by a vehicle collision when the vehicle collision is detected.
