摘要:
In a travelling wire EDM apparatus the thermal stresses of the electrode wire are substantially reduced by detecting the position of the triggering electrical discharges preceding the machining electrical discharges, and by controlling the supply of the machining electrical discharge current at one end of the machining zone, at the other end of the machining zone or at both ends of the machining zone. When a machining electrical discharge is located between one end of the machining zone and a first reference position, the machining current is applied at that end. When the electrical discharge is located between the other end of the machining zone and a second reference position, machining current is supplied at that second end. When the electrical discharge is located between the two reference positions, the machining current is applied simultaneously at both ends of the machining zone.

Disclosed is a method of administering an interleukin-2 receptor (IL-2R) antagonist to a subject to treat an autoimmune disease. In particular embodiments, the IL-2R antagonist is an anti-IL-2R monoclonal antibody specific for one or more chains of the IL-2R, such as the alpha-chain, for example daclizumab. In other particular embodiments the autoimmune disease is multiple sclerosis. In certain embodiments administration of interferon-beta is combined with administration of an antagonist of the IL-2R to provide significant clinical improvement in a subject with an autoimmune disease.
摘要:
A variety of therapies are used to treat autoimmune diseases such as multiple sclerosis. However, there is no single therapy that can be used to treat all subjects. Thus, a method is provided to determine if a subject with an autoimmune disease, such as multiple sclerosis, will respond to a therapeutic protocol. The method includes analyzing the expression of genes expressed by the immune system. Although the expression of a single gene can be assessed, such as interleukin-8, the methods include evaluating the expression profile of a subject using an array (such as a microarray) to determine if the subject is appropriately responding to the therapeutic protocol.

A device can indicate the total load of a brake disk made of carbon-fiber-reinforced ceramic material. In order to create such a device, which can be used for brake disks and other friction elements made of carbon-fiber-reinforced ceramic material, an indicator element can be provided in the brake disk starting from the friction surface. The oxidation stability of this indicator element is reduced with respect to the material of the brake disk.

The present invention relates to cleaning compositions which comprise the insect repellent ethyl 3-(N-butylacetamino)propionate and the use of this insect repellent in all types of cleaning compositions for repelling insects. This invention furthermore relates to a method for cleaning and for simultaneously repelling insects in which cleaning compositions comprising ethyl 3-(N-butylacetamino)propionate are used.
摘要:
In the process of machining by electroerosion, there is adjusted during a first transitory phase the machining current increase of the discharges after triggering a discharge between the electrode and the piece, such that a parameter connected to this increase will be substantially equal to a reference value corresponding to a minimum wear value of the electrode. Then, the machining current is maintained during a second phase at a reference value. The adjustment is carried out by acting on the adjustable internal voltage of a low impedance adjustable voltage source connected between the electrode and the piece. The adjustment can be carried out by a servo control loop with a regulator of the internal voltage, a device for generating discharges, parts adapted to determine the slope of increase of the current of a discharge, a member determining the mean slope of N discharges and a member adapted to compute the difference between the mean slope and a pre-established reference slope.

A brake disk made of a fiber-reinforced material includes two assembled friction rings. The friction rings, on interior sides, are provided with ribs. The two friction rings are supported with respect to one another along at least a portion of the ribs. In order to provide a suitable shaping of faces of the ribs, faces used as coupling faces are constructed such that a coupling of the friction rings is caused in precisely one rotating direction and, in a particular case, such that the coupling faces are arranged in an alternating manner.

A braking device for wheels of vehicles such as trailers includes a caliper in which brake linings are guided. Between these linings, at least one brake disk is displaceably held on driving toothing of a wheel hub. A pneumatically operable mechanical adjusting device interacts with the brake linings. The braking device includes at least one brake disk in a caliper which is fixed. On one end, the caliper is connected by a fastening element with an axle element of the vehicle. On the caliper, an enclosing housing for bearing the adjusting device is held. By way of a bearing plate, the adjusting device is also supported on the caliper. Pressure pistons of the device are guided by a one-part yoke in a jointly axially adjustable manner and can be acted upon by pressure with respect to the brake linings and the brake disks.

A brake disk, particularly a ventilated brake disk, has at least one friction ring connected with a brake disk chamber by fastening screws. Each fastening screw is provided with a cylindrical projection which is adjoined on the end side by a threaded portion. The cylindrical projection of the fastening screw is arranged in a bore of the friction ring. The threaded portion of the screw can be screwed into the brake chamber.
