Abstract: Method for finish-grinding premachined annular disc-shaped metallic workpieces (1), in particular motor-vehicle brake discs with brake disc head (2) and annular disc-shaped brake disc rim (3). A workpiece receptacle is driven so as to rotate about a workpiece receptacle axis, and a grinding tool receptacle (4) is driven by a drive shaft (5) so as to rotate about a grinding tool receptacle axis substantially parallel to the workpiece receptacle axis. The work is carried out with a grinding tool designed as a ring tool (6) with ring-shaped grindstone (7). The ring tool (6) is subject to a follow-up control without ball-and-socket joint on the workpiece (1) to be ground and to this end is connected, to be elastically compliant on all sides, to the drive shaft (5) of the grinding tool receptacle (4) so that the workpiece receptacle axis and the grinding tool receptacle axis can be set askew relative to one another by the follow-up control. <IMAGE>

Abstract: The invention relates to a device for transferring filter rods into a pneumatic conveying line by means of a troughed drum which removes the filter rods from a stock, transversely to their axis, and terminates with a lengthwise axis in the enclosing region of the sealing block. The object is to reduce the wear on such a device and to improve its performance. This is achieved by means of a troughed drum (1) which is mounted free of contact with respect to adjoining circumferential and end surfaces (17 and 19 respectively) and maintaining a play or gap (25 and 31 respectively). This arrangement lengthens the service life of the adjoining sealing block and, by means of a defined, permanent by-pass air-flow, achieves an increased selection frequency of the filter rods. <IMAGE>

Abstract: This invention relates to an improved process for the preparation of methylcyclohexane diamine wherein meta-toluenediamine is contacted with hydrogen in the presence of a hydrogenation catalyst. The improvement resides in utilizing a hydrogenation catalyst comprising rhodium carried on a support and carrying out the hydrogenation in the presence of a C₃-C₁₀ secondary alcohol as a solvent. With the use of rhodium carried on a support as a catalyst, coupled with the use of the secondary alcohol solvent, one obtains high yields with excellent catalyst life.

Abstract: Organosiloxane compositions comprising specified combinations of MQ resins and liquid polyorganosiloxanes are applied as molten materials to form coatings that are non-flowable under ambient conditions and that can initially be remelted by heating the coating above its flow transition temperature. In the presence of moisture, the flow transition temperature of the coating gradually increases due to the reaction of hydrolyzable groups on the polyorganosiloxane ingredient until the coating is converted to a non-flowable, resin reinforced elastomer. Preferred coatings are non-transferable at 25°C. within ten minutes following application.

Abstract: This invention relates to flexible internal liners for reducing the amount of oil spilled by oil tankers due to groundings, collisions, and other major accidents. The liner comprises a flexible oil-resistant impermeable plastic or rubber, which preferably is reinforced by steel mesh or woven high-strength fibers. In one embodiment, an independent segment is provided in each bay between two longitudinal stiffeners. The edges of each liner segment are coupled to the stiffeners, near the ends of the stiffeners, to provide enough material for the liner to be pushed inward if a collision or grounding occurs. The edges can be secured by detachable clamps, such as bars which are tightened using threaded nuts and bolts; these will provide watertight seals during normal operation, while allowing the segment to be detached and opened when the internal surface of the hull is periodically inspected. If desired, each liner segment can be held snugly against the outer shell using devices which have low tensile strength (such as thin cables) and which are designed to yield and break, thereby releasing the liner segment, if a rock or other intruding item breaches the outer shell and pushes the liner inward. In an alternate embodiment, a larger liner segment can be positioned over a plurality of bottom shell stiffeners between a longitudinal bulkhead and a girder or web, which may be positioned over the keel, in a "waterbed" configuration which rests upon a layer of oil or water that fills the stiffener bays. These designs allow the liners to be pushed inwardly without requiring any sliding or dragging of a liner across a steel surface.
