Abstract: The present invention provides a valve actuation system comprising a valve train for actuating a valve, the valve train including actuating elements and a valve lash, and a valve lash adjustment system for adjusting the valve lash, wherein the valve train and the valve lash adjustment system do not share any common actuating elements.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment request a program or programs to tune themselves to run faster or slower if a service class is not meeting its performance goal. In an embodiment, the program is repeatedly requested to incrementally tune itself until the performance goal is met or until no further improvement occurs. In various embodiments, the programs to be requested to tune themselves are selected based on whether the programs are bottlenecks for the service class, whether the programs do the majority of work for the service class, whether the programs easily meet their own performance goals, or whether the programs are low priority. In this way, the programs may be performance tuned in a way that is more effective and less intrusive than by adjusting global, system-level resource allocations.

Abstract: A door hinge and a method of its use is provided which is suitable for use with glass shower screen doors. The method involves cutting a pair of circular cut-outs at a side edge of the door near the top and bottom of the door respectively. After toughening of the cut-out portions of glass, a hinge in accordance with this invention is mounted in each cut-out portion. The hinges each have a first arm which has a circular door mounting portion of substantially the same diameter as the cut-outs which are located in the cut-outs. The hinges each have two clamping parts, one part is fitted to abut with one face of the door, and the other part is fitted to abut with the other face of the door. Each part is fitted to immediately surround the respective cut-outs. The hinge then has screw holding means which holds the parts together and clamps the door. The second arm of the hinge can be mounted directly to a frame member, such as a jam member or to a further glass panel.

Abstract: Gels of oil-extended methacrylate-alkylene-methacrylate (M-A-M) triblock copolymers having higher glass transition temperatures than known styrene-alkylene-styrene triblock gels. The preferred M-A-M triblocks for making the new gels have polymethylmethacrylate end blocks and butadiene or ethylene/butylene mid-block, and are synthesised by methods in the public domain (inter alia Shell EP-A-0431706). Includes gels of new triblocks having end blocks of higher alkyl (e.g. isobornyl) methacrylate homopolymer or copolymers. Mixed methyl- and higher alkyl-methacrylate end blocks are preferred to reduce gel-formation problems which may arise from solubility parameter of homo-isobornylmethacrylate end blocks being too close to that of extender oil. Includes gels of new multi- (preferably penta-) block copolymers including styrene (S) blocks, e.g. M-S-A-S-M.
