20080215160 | Resurfacing-Hip Implant Construction Set - Described here is a set for the construction of a resurfacing hip implant. It comprises a thin metal cup for cemented insertion into the natural acetabulum, a thin metal cap for cemented placement upon the natural femoral head, and an inlay which can be placed in the cup of the acetabulum as a sliding partner for the cap for the femoral head. | 09-04-2008 |
20090018666 | Set For Creating An Offset-Resurfacing Hip-Joint Implant - A set is provided for creating an offset-resurfacing hip-joint implant. The set includes a 1 to 1.5 mm thick metallic acetabulum shell ( | 01-15-2009 |
20090112330 | Ball joint or cap implant for an artificial hip joint - A ball joint or cap for an artificial hip joint is described that is suitable for carrying out a rotating or pivoting motion in an artificial hip joint socket, with a gap being provided for a natural fluid film (synovial fluid) between itself and the artificial hip joint socket, and with regular depressions without interconnecting channels between them being recessed in areas of its surface. It is proposed that its surface in the polar area is smooth and without depressions, that an area is provided in an intermediate area between the smooth polar area and its equator, in which depressions are recessed with hole widths between 1.0 mm to 3.0 mm, that adjacently in the intermediate area in the direction of its base edge, further depressions are recessed, the hole widths of which become steadily smaller, the closer they lie to the base edge, with hole widths between 0.5 mm and 1.0 mm. | 04-30-2009 |
20100191344 | Set for Producing a Resurfacing Hip Implant - Described here is a set for the construction of a resurfacing hip implant. It comprises a thin metal cup for cemented insertion into the natural acetabulum, a thin metal cap for cemented placement upon the natural femoral head, and an inlay which can be placed in the cup of the acetabulum as a sliding partner for the cap for the femoral head. Also described are methods of using and implanting the implant. | 07-29-2010 |
20110190906 | Connection Adapter - A connection adapter between a rigid transcutaneous implant can be anchored intracorporeally in a femoral stump, and a part of an extracorporeal orthopedic knee joint. The connection adapter comprises a first coupling part for connection to the transcutaneous implant and a second coupling part for connection to the knee joint. The second coupling can be connected releasably to the first coupling part. A safety coupling is arranged in the interior of the second coupling part and transfers a torsional moment between the first coupling part and the second coupling part and slips through when an adjustable maximum value of the torsional moment is exceeded. | 08-04-2011 |

20100105586 | LUBRICATING GREASE COMPOSITION - The invention relates to lubricating grease compositions having a base oil mixture based on oils having viscosities (ISO VG 2 to ISO VG 1500) that are standard for industrial lubricants, an ionic liquid, a thickening agent, e.g., based on a polyurea compound and conventional additives that can be used at current service temperatures that are higher than 120° C. to 260° C., in particular at a service temperature in the region of high service temperatures that are higher than 180° C. to 260° C. and also at low temperatures as low as −60° C. The invention also relates to a method for producing said type of lubricating grease compositions. | 04-29-2010 |
20100187481 | USE OF IONIC LIQUIDS TO IMPROVE THE PROPERTIES OF LUBRICATING COMPOSITONS - The invention relates to the use of ionic liquids for improving the lubricating effect of synthetic, mineral and native oils. The invention relates in particular to an improved lubricating composition that is protected from thermal and oxidative attack. | 07-29-2010 |
20110092399 | LUBRICATING GREASE COMPOSITION BASED ON IONIC LIQUIDS - The invention relates to the use of ionic liquids for production of water-resistant lubricating grease compositions, which are used in a temperature range from at least 30° C. to at least 180° C. and have good anticorrosion properties. | 04-21-2011 |
20120202724 | METHOD OF USING IONIC LIQUIDS TO IMPROVE THE LUBRICATION OF CHAINS, STEEL BELTS, WHEEL BEARINGS, ROLLER BEARINGS, AND ELECTRIC MOTORS - A method in which an improved lubricating composition containing ionic liquids is used to enable operation of chains, steel belts, wheel bearings, roller bearings, sliding bearings and electric motors for at least 48 hours by reducing the evaporation loss and the lackification tendency of the lubricant due to the lubricant being protected against thermal and oxidative attack. | 08-09-2012 |
20140162914 | Use of nanoscale materials in a composition for preventing symptoms of fatigue in the surface-closed structure of drive elements - A composition for prevention or reduction of fatigue damage, especially trench formation or micropitting, of the surfaces of drive elements, is provided that comprises 0.1 to 40% by weight of surface-modified nanoparticles, and 99.9 to 60% by weight of a carrier material suitable for application to the drive element surfaces. | 06-12-2014 |
