Patent DE-4317068-A1 (DE)
Title: Arrangement for cleaning surfaces or surface regions of underwater devices
Inventor: HALLAS ERNST DR RER NAT
IPC: B08B3/12
Filed: 1993-05-21
Abstract: The invention relates to an arrangement for cleaning surfaces or surface regions of underwater devices. A multiplicity of cleaning possibilities, for example using wipers, water under pressure or compressed air, are known for cleaning underwater devices. These methods have the disadvantage in particular that the cleaning is costly and can only be carried out during certain intervals. Known ultrasonic cleaning methods cannot be used under water. The invention proposes an arrangement in which the surface to be cleaned is excited to perform ultrasonic oscillations and the cleaning can therefore also take place under water and above all continuously.
Patent DE-4324325-A1 (DE)
Title: Optical component mfr. by reactive etching - of metal oxide dielectric, esp. tantalum or hafnium oxide
Inventor: RUDIGIER HELMUT DR
IPC: C23F4/00
Filed: 1993-07-20
Abstract: Prodn. of a component, esp. an optical component, having a layer system including at least one dielectric layer with one or more stepped thickness changes, involves (i) applying, onto a substrate, a dielectric layer of the type MeOx, in which Me is a metal of mass at least 44 and x is chosen such that the absorption coefficient for light of wavelength 308 nm is max. 0.01; and (ii) reactively etching the layer with an activated gas to form the stepped thickness. USE/ADVANTAGE - The dielectric MeOx layer is esp. suited to reactive etching, is highly refractive even in the UV region, and can be profiled by reactive etching with high selectivity and etch rate. The alkaline earth metal dopant gives an orange indicator colour when the layer surface is reached during reactive etching by means of a glow discharge. The Y2O3 etch-stop layer is etched less than etch-stops such as Al2O3.
Patent DE-4327068-A1 (DE)
Title: Valve gear of an internal combustion engine
Inventor: HOERL-LIEGL ALBERT
IPC: F01L1/18
Filed: 1993-08-12
Abstract: A rocker arm actuated by a cam is supported on one side on the stem of a lifting valve - in a known manner - and on the other side on a support spring, the spring force of which is adjustable. For this purpose the said support spring is guided by a displaceable spring seat. Since the spring force of the support spring in its maximum load condition is greater than the force of the valve closing spring in its minimum load condition, in which the lifting valve is in its closed position, different valve lifting behaviours can be adjusted by displacement of the spring seat. In intermediate positions of the spring seat between its two limit stops valve lifting behaviours thereby result which lie at least essentially between the valve lifting behaviours which result with spring seat bearing on the limit stops.
Patent DE-4337931-A1 (DE)
Title: Gas tension spring
Inventor: HAHN GUENTHER
IPC: F16F9/02
Filed: 1993-11-06
Abstract: A gas tension spring contains a cylindrical inner tube which forms a cylinder for a working piston guided in the cylinder in a longitudinally displaceable manner and carrying a piston rod, which is led out in a sealed-off manner. The inner tube is surrounded by an outer tube and forms together with the latter a cylindrical annular space which is fluidically connected to the rod-side cylinder chamber and to the inner space of the piston rod. The said hollow spaces are provided with a common gas filling under pressure. The gas tension spring has a flatter spring characteristic than known gas tension springs and is mounted in the pressureless state. After assembly, it is filled with gas by a cap-shaped closure part slipped onto the outer end of the piston rod. The closure part is held on the piston rod in a positive-locking manner.

Title: System for cross=cutting and separation of bars of desired cross=section and profile
Inventor: SORG MANFRED
IPC: B23Q1/48
Filed: 1994-08-03
Abstract: The principle motor (1) drives the toothed belt (1) and the connecting gear (4) via the synchronous gear (2). Parallel to this the cam (15) is driven by a synchronous gear (5), a toothed belt (6) and a further synchronous gear (7). The rotation speed drive (8) has no influence over the speed of the final synchronous gear (13) when the second motor (9) is at rest. The final synchronous gear drives the cam via a toothed belt (14). Movement of the cam operates the knife mechanism. By adjustment of the second motor, an angular adjustment of the rotation speed drive is made which moves the connecting gear (4) and the cam through an angle of 0 deg.-110 deg. which translates the movement to the knife housing via the connector (17).

Title: Tensile force transmission assembly acting on a body to a bearing
Inventor: KLOTZ THOMAS
IPC: H01R13/58

Abstract: Dans un dispositif a laser (1) avec voie de rayonnement repliee des miroirs sont situes aux extremites de l'espace interelectrode. Ces miroirs sont du type qui changent la direction du faisceau laser et/ou sont semi-transparents (18 a 21). Ces miroirs sont formes ou se trouvent sous des angles tels qu'au moins un partie du rayonnement laser est reflechi ou devie a la maniere d'un laser en anneau. Dans une telle utilisation du milieu actif on obtient une montee plus rapide de l'amplication et, en resonateur instable, une bonne dissipation de l'energie en regime monomode. Pour autant que les cotes frontaux (8, 9) du boitier qui entourent le dispositif a laser sont totalement et/ou partiellement reflechissants les problemes d'ajustage tombent. La forme de l'impulsion peut etre modifiee dans le temps par un element (27) prevu dans la region couplee du faisceau laser (17') element qui est un commutateur optique actif ou un modulateur a facteur de qualite.

Patent WO-9118700-A1 (WO)
Inventor: VON HAAS RAINER
IPC: B23B51/04
Filed: 1991-05-22
Abstract: The invention concerns a drilling tool for drilling bores in solid metal, the tool having a shank and, at the front end of the shank, several geometrically similar cutter blades disposed at different radial distances from the shank and staggered with respect to each other with the same angle at circumference. The working areas of the cutter blades overlap and each blade has two cutting edges of the same length. Adjacent cutting edges inclined at an obtuse angle to each other engage simultaneously, and that cutting edge which is engaged of the inner cutter blade extends slightly beyond the drill axis. In order to take account of all the forces, over and above the radial components, involved in the boring operation, it is proposed that at least one of the bisects (W1, W2) of the angle between the two cutting edges (11, 12; 21, 22) of a cutter blade (10, 20) is inclined at angle ($g(a), $g(b)) of up to 25 to the longitudinal axis (40) of the shaft and, in addition, that at least one of the bisects is at an angle other than zero to another bisect so that the sum, not equal to zero, of the radial force components (FR?) resulting from all the effective cutting blades which are engaged and the sum of the corresponding horizontal force components (FH?) give an overall resultant force (FRES?) on the cutting edges which acts towards the outermost cutter blade (20) or at an angle ($g(d)) of not more than 45 to this direction.

Abstract: Die Oberflächenstruktur für eine zur Beaufschlagung eines Materials vorgesehene Walze (2) weist durch einen Elektronenstrahl (3) erzeugte Ausnehmungen (22) auf. Die Ausnehmungen (22) sind aus Kratern und die Krater umgebenden Kraterwällen (62) ausgebildet. Die Ausnehmungen (22) sind in einem zweidimensionalen Raster mit einer konstanten Rasterstruktur angeordnet. Das Raster besteht aus sich im wesentlichen parallel zueinander erstreckenden Ausnehmungen (65) und die Ausnehmungen (22) in benachbart zueinander angeordneten Ausnehmungsreihen (65) sind jeweils versetzt zueinander angeordnet. Die Ausnehmungen überlappen sich mindestens in Richtung der Ausnehmungsreihen bzw. in einer quer zu den Ausnehmungsreihen verlaufenden Richtung und bilden dabei ein quasistochastisches Raster. Bei dem Verfahren zur Erzeugung der Oberflächenstruktur wird durch den Elektronenstrahl im Bereich der Oberfläche der Walze ein aus den Ausnehmungen gebildetes Raster mit einer konstanten Rasterstruktur erzeugt. Durch die sich teilweise überlappende Anordnung der Ausnehmungen wird eine pseudo-stochastische dreidimensionale Oberflächenkontur generiert.
