Abstract: A bicycle handlebar includes a central part for connection with a handlebar stem or formed integrally with the same. Two outer parts are detachably connected with the central part such that they are variable in their position. The width of the handlebar can be adjusted individually.

Abstract: A bicycle drinking bottle is provided, which is particularly suited for time trial bicycles and triathlon bicycles. The bicycle drinking bottle includes a liquid container having two opposing side walls, a rear wall, a front wall, a lid, and a bottom element, with the two side walls including recesses for receiving fixing elements that are connected with a handlebar of a bicycle steering structure. A bicycle steering structure system including a handlebar with such a drinking bottle connected thereto through two fixing elements is also provided.

Abstract: A bicycle grip includes a sleeve which in the mounted state surrounds a bicycle handlebar. The sleeve is surrounded by a grip element or is enclosed by it by molding. A cable duct is integrated into the sleeve. Locking elements are connected to the sleeve so as to realize fixation of the bicycle grip to a handlebar end in a simple manner. A bicycle grip/handlebar system including a correspondingly designed bicycle handlebar and a bicycle grip are also provided.

Abstract: The invention describes a spark plug, which comprises an inner conductor, an insulator enclosing the inner conductor, a spark plug body enclosing the insulator and two electrodes forming a spark gap. The first electrode is a center electrode connected to the inner conductor in an electrically conductive manner and the second electrode is a ground electrode connected to the spark plug body in an electrically conductive manner. At least one of the electrodes has a precious metal region, adjoining the spark gap and consisting predominantly of platinum, iridium or an alloy of both and containing additionally at least one brittle metal. The precious metal region consists of a base material predominantly containing platinum and/or iridium, which comprises a coating with a brittle metal, which is more brittle than the base material.

Abstract: A bicycle fork with an integrated brake unit, in particular for racing bicycles and time-trial machines, comprises a fork crown connecting two fork legs with each other. A bottom bearing seat is connected with the fork crown. A brake unit is arranged below the fork crown, wherein an activation element, such as a Bowden cable or the like, for activating or actuating the brake unit is passed through the bottom bearing seat.

Abstract: A double bridge bicycle fork with integrated brake unit, suited especially for racing bicycles and time-trial machines, comprises two fork legs connected by a fork crown. Further, a bottom bearing seat is connected with the fork crown. A steer tube is provided in front of the rotational axis of the fork, seen in the direction of travel, said axis being defined by the bottom bearing seat and the upper bearing seat. The steer tube is connected with the stem by means of screws. This makes it possible not to provide a rigid head tube between the two bearing seats, but to arrange a sleeve in the embodiment illustrated that has an opening for passing actuation elements therethrough, such as switching or brake cables.

Abstract: To make a jacketed thermoelement, two metal wires, one of which is pure platinum, preferably of at least 99.9, and even higher purity, and the other being a platinum/rhodium alloy are included in a ceramic element. The wires are first threaded into capillary openings of a cylindrical ceramic element which is jacketed by a jacket of platinum-rhodium alloy or INCONEL (TM). The initial assembly is hammered, thereby crashing the ceramic, and drawn to reduce the outer diameter of the metal jacket tube to fit the inner diameter of an auxiliary tube, for example of a copper-tin alloy which is fitted over the metal jacket tube. The thus formed composite is then passed through a sequence of drawing dies, preferably in a single drawing pull, in which each die reduces the cross-section by about 9-10%, until the desired outer diameter of the metal jacket tube (4) is reached; this diameter may be in the order of 0.3 mm, after starting with an outer diameter of just under 5 mm.

Abstract: Surface treatment for hard or dehydrated hydrophilic contact lenses, to reduce the deposit of impurities thereon, comprising subjecting the lens, after shaping and polishing, to a gas discharge, e.g., in an oxygen atmosphere.
