Title: Polycrystalline sintered articles based on silicon nitride, having a high fracture toughness and hardness
Inventor: STEINMANN DETLEF DIPL ING DR
IPC: C04B35/584
Filed: 1985-08-23
Abstract: The invention relates to polycrystalline sintered articles which consist of at least 66 % by weight of a crystalline Si3N4 phase, of which at least 90 % by weight are in the ss-modification, and of up to 34 % by weight of secondary intergranular oxide-, carbide- and/or nitride-based grain boundary phases. At least 25 % by weight of the secondary grain boundary phases consist of a fully crystalline lanthanum-aluminium garnet phase, the crystalline lanthanum-aluminium garnet having been prepared, before the production of the sintered articles, from lanthanum oxide and aluminium oxide in a molar ratio of 1:1. These polycrystalline sintered articles are produced by sintering with and without applied pressure from silicon nitride powders with an impurities content of not more than 4.0 % by weight, oxide-based sintering additives and, if appropriate, further carbide- and/or nitride-based refractory additives, using crystalline lanthanum-aluminium garnet powder as at least one sintering additive which has been prepared, before mixing with the other constituents and before sintering, from lanthanum oxide and aluminium oxide in a molar ratio of 1:1 by heating to temperatures from 1700 DEG  to 1900 DEG C. When at least 70 % by weight of silicon nitride powder is used, up to 30 % by weight of the crystalline lanthanum-aluminium garnet powder can be used alone or as a mixture with other oxide-, carbide- and/or nitride-based additives, but altogether ...

Title: Installation having devices for removing and replacing windings of electrical machines
Inventor: VESER FRANZ
IPC: H02K15/00
Filed: 1985-08-30
Abstract: In order to remove the windings (25) from the stators or rotors of electrical machines and to replace them by new windings, the winding carrier (W) is positioned and fixed centrally in the inner ring of a clamping-in ring (5) which is mounted vertically in a fixed position. The rotatably supported inner ring can be motor-driven via controllable switching means, in such a manner that the required continuously variable rotational movements of the winding carrier (W) which is held in the inner ring can be carried out while the winding overhangs are being separated on one side, while the bonded windings (25) and slots are being heated, during the subsequent withdrawal of the windings (25) from the winding carrier (W) and while the windings are being inserted into the cleaned slots again. This multiple function of the clamping-in ring (5) simplifies the handling of the installation and improves its method of operation. The transmission and supporting elements (34 to 43) for the tension force of a pressure cylinder (33) can be moved into the required position together, as a unit. <IMAGE>

Inventor: GAZYAKAN UENAL
IPC: F16D35/02
Filed: 1985-10-01
Abstract: A viscous clutch for use as an engaging clutch for a vehicle differential gear system, with a working chamber (4) and a storage chamber (5). A pump (6, 7, 8) supplies liquid from the storage chamber (5) into the working chamber (4). When a pre-set relative rotation speed is exceeded, first valve (3, 12) closes a first return flow line (19, 20); when a pre-set temperature is exceeded a second valve (12, 31) opens a second return line (32, 36) from the working chamber (4) to the storage chamber (5). The torque and heat loss of the viscous clutch are low at a low relative rotation speed and/or high temperature. The torque is large only when the valves simultaneously exceed a pre-set relative rotation speed and fall below a pre-set temperature.

Patent DE-3546449-A1 (DE)
Title: Bending apparatus
IPC: B21D7/022
Filed: 1985-03-12
Abstract: The invention relates to a bending apparatus for rod- or strip-shaped material with a bending station arranged in a working plane in front of a feed device, in which a cutting-off device consisting of an opposing cutting edge held ready above the working plane and of a cutting element which can be pushed out perpendicularly to the working plane is arranged in the vicinity of the location at which the material is bent. In a known bending apparatus, the cutting element cannot act directly at the bending location. Modifications to the cutting-off apparatus are virtually impossible or possible only with the expenditure of a considerable amount of time. According to the invention, the cutting element is now to be arranged directly below the bending location and the opposing cutting edge is to be arranged on a movable supporting device which can be rotated into the cutting position. There is thus a free choice of cutting location directly at or shortly after the bending location, particularly using the feed device.

IPC: B65D30/24
Filed: 1986-01-07
Abstract: In a valve bag having a tubular valve insert whose internal walls rest against one another in the closed state when the valve bag has been filled, a separating and closure sheet is provided between the internal walls resting against one another. In the unfilled state of the valve bag, this separating and closure sheet separates mutually opposite adhering and sealing regions of the internal walls. In the filled state, this separating and closure sheet releases the adhering and sealing regions so that they can rest and seal against one another. The adhering and sealing regions are preferably mutually corresponding different touch-and-close tape regions.

Title: Quiet-operating diamond-carrying cutting disc for marble and garnet
Inventor: TASOULIDIS CHARALAMBOS
IPC: B24D5/12
Filed: 1987-06-19
Abstract: The present invention relates to a quiet-operating cutting disc for marble, garnet and other rocks. The aim of the invention is achieved in that depression-seat supports are provided on one or both disc sides and are filled with metal sheets which are bonded on using flexible adhesive and have a shape and dimensions corresponding to the depressions. According to another variation of the invention, the holes are first partially filled with plastic, whereupon the thin metal sheets are bonded on. According to the described construction, the diamond-carrying cutting disc for marble, garnet and other rocks has the facility to eliminate the vibrations resulting at the circumference of the disc, owing to the fact that the thin metal sheets bonded onto the depressions act as a barrier against the advance of the vibrations towards the centre of the side. <IMAGE>
