Patent DE-3700758-C2 (DE)
IPC: B21D15/04
Filed: 1987-01-13
Granted: 1988-11-24
Abstract: The production of the internal thread of a connection sleeve (4), which is used as a coupling element for parts of a rock support or of a drill rod, by machine-forming, in particular by thread-cutting, entails great effort since, in the round thread used here, a considerable amount of machining work is required. Furthermore, it is disadvantageous in this application in the machining of the thread that the long-term strength of the connection sleeve is considerably impaired due to the notch effect in the base region of the thread turns. A connection sleeve and a method for its production are proposed, in which the internal thread is produced without machining by shaping the outside of the connection sleeve (4) in the manner of a thread so that the image of this shaping forms the internal thread to be produced on the inside. Apart from the increase in strength caused by the non-cutting shaping, which is usually cold shaping, due to material reinforcement, the further advantage results that the shaping required here can be applied in a single operation so that the production costs of connection sleeves (4) of this type can be reduced. Furthermore, it is advantageous that the external thread, interacting with the internal thread of the connection sleeve, of the components to be connected to one another can have a basic shape which corresponds to the outside thread-type shaping of the connection sleeve (4). <IMAGE>

Title: Tow tug for moving aircraft
Inventor: CUERTEN FRANZ JOHANNES DIPL IN
IPC: B64F1/10
Filed: 1988-01-22
Granted: 1997-05-28
Abstract: The tug is backed onto the nose wheel of the aircraft with the wheel inside the forked rear frame. Extending grabs secure the wheel and pull it further into the tug and onto a single support platform. This tips about a transverse axis and lifts the wheel off the ground for towing. The platform is further supported on parallel levers to tilt to either side as the combination corners. This compensates for the tilt action of the nose wheel suspension. Servo cylinders control the tilt setting of the platform in either direction. The height adjustment of the platform is controlled by sliding supports. The wheel grips are provided by roller grips gripping onto the tyre.
Patent DE-3916115-C2 (DE)
IPC: C23C4/123
Filed: 1989-05-16
Granted: 1992-12-10
Abstract: The invention relates to a method for the production of rotationally symmetric bodies by atomising a metal melt, collecting the resulting metal droplets on a rotating surface, the surface being completely covered with metal droplets after one complete revolution, continuing to move the surface, while maintaining the rotation, out of the collecting position or plane of atomisation. In order to improve known methods in such a way that the body produced has as uniform a diameter as possible over its total length, it is proposed that the position of the plane of atomisation be determined continuously during the feed of metal droplets and the speed of movement of the surface and/or the mass flow of the metal droplets be controlled so that a predetermined ideal position of the plane of atomisation is maintained.

IPC: F23J15/00
Filed: 1989-11-27
Granted: 1993-08-12
Abstract: The method for reducing the nitric oxide concentration in the waste gas flow of combustion processes consists of the introduction of chemicals, e.g. ammonia, sal ammoniac, urea, calcium cyanamide, into the waste gas flow, wherein the waste gas flow is marked by an additional compulsorily produced strong turbulence and the waste gas flow is compressed prior to this turbulence zone. The introduction of the treatment medium is effected shortly before the turbulence zone and the waste gas flow is relaxed and calmed subsequent to the turbulence zone. In order to implement this method, a furnace is provided which comprises a grate and a waste gas flue consisting of an ascending waste gas flue and a descending waste gas flue adjoining the latter. The current flow of the waste gas flow is substantially S-shaped proceeding from the furnace grate to the downwardly directed waste gas flue, wherein the change of direction in the lower area is substantially smoother than in the reversing space. In the upper portion the waste gas flue the waste gas flow is compressed by means of corresponding inclination and consequent constriction of the cross section of the waste gas flue. Spray nozzles are provided at the commencement of the upper portion of the ascending waste gas flue in order to introduce chemicals. The introduction of the chemicals is effected shortly before the compression and the production of strong turbulence.
