Patent DE-3814907-A1 (DE)
Inventor: FLORIN WOLFRAM DR ING
IPC: C21C5/46
Filed: 1988-05-03
Abstract: The invention relates to a process for adding alloying products to molten metal, in particular molten steel during the tapping of a converter into a casting ladle, wherein the alloying products are introduced in the form of a jet into the casting jet of molten metal flowing out, the jet of alloying product enclosing an angle with the vertical plane formed by the molten metal casting jet. The invention is characterised in that, with a changing position of the molten metal casting jet due to a changing casting inclination of the converter or due to a changing size and position of the tapping hole of the converter as a result of wear thereof and/or with a changing position of the alloying product jet due to a changing composition of the alloying product, the direction of the alloying product jet is continuously adjusted for combining the two jets. <IMAGE>

Title: Length-adjustable boom
Inventor: MARKER HANNES
IPC: F16B7/10
Filed: 1988-05-09
Abstract: The length-adjustable boom consists of a front and a rear boom part. The end sections of the spar pieces of the rear boom part are inserted into tubular spar pieces of the front boom part and are connected to said pieces via a locking device at a length which can be selected in steps. The locking device consists of an internal sleeve (5) which is connected to the outer spar piece (2) and from which a tongue (8) having an inner locking member (9) is cut free, and an outer sleeve (6) which can be rotated between a release position and a locking position. In the locking position, an internal attachment (21) of the outer sleeve (6) presses against a cam surface (11) of an outer projection (10) of the tongue (8), as a result of which a rotationally secure connection is ensured between the spar pieces (1, 2) (Fig. 1). <IMAGE>

Patent DE-3831599-A1 (DE)
Inventor: HERMSTEDT ECKHARD DR
IPC: A43B5/02
Filed: 1988-09-14
Abstract: In sports shoes, in particular football boots, the problem exists for players of striking the ball in such a manner that the impulse exerted on it is in the direction of the centre of gravity. In football boots which follow the anatomy of the human foot, there is only contact in the form of a point or of a line or guidance in the form of a small area, so that even slight deviations in the point of striking the ball impair the precision. According to the invention, a sports shoe is designed in such a manner that the enveloping surface of the upper material is formed in a plane manner or curved in a concave manner in the region of the instep. By means of the concave design, there are two lines of contact upon shooting, as a result of which the ball is guided by the foot for a decisively short time and the precision is thus increased.   <IMAGE>

Title: Overvoltage suppressor having a spark gap in air
Inventor: BOY JUERGEN
IPC: H01T4/12
Filed: 1988-10-18
Abstract: In the case of an overvoltage suppressor having a parallel-connected spark gap in air, in order to reduce the design and manufacturing cost for that spark gap in air which is assigned to the second electrode, the suppressor (22) is enclosed by a cylindrical metal casing (28). One edge (19) of this metal casing makes contact with the first electrode (3) of the suppressor, while the other edge (14) is bent inwards and grips the auxiliary electrode (27), which is placed on the second electrode (25) with an insulating washer (26) being interposed. The external diameter of this auxiliary electrode (27) is larger than the external diameter of the second electrode (25). In order to centre the suppressor (22) in the metal casing (28), the distance between the suppressor and the metal casing is less, at at least three circumferential points, than the required radial safety distance between the metal casing and the second electrode. This can be achieved, for example, by means of a plurality of depressions (30), which are in the form of spots and are arranged distributed uniformly on the circumference, in the metal casing, or else by means of an annular constriction (29). <IMAGE>

Title: Separating mechanism for a collating machine
Inventor: BOETTCHER WINFRIED
IPC: B65H83/00
Filed: 1989-05-06
Abstract: The separating mechanism for collating machines is used when collating printed sheets (1) to form complete blocks (29). According to the invention, the printed sheet (1) separated from a pile magazine (2) by means of the grippers (4) of the gripper drum (3) is released under cam control above the support table (12) and, at the same time, is spread out on the support table (12) by a sheet conveying element (17) moved by revolving coupler mechanism. The coupler mechanism can be adapted via a gear mechanism to the number of printed sheets separated per revolution of the gripper drum. The printed sheets (1) delivered, spread out and determined by a height-adjustable stop (13) are collated to form the block by the carrier (15) which acts in the direction of the gripper drum axis. The action of the sheet conveying element (17) enables production to be increased with a good quality of the separation process, which has a direct influence on the operating processes downstream of collation. <IMAGE>
Patent DE-3920289-A1 (DE)
Inventor: ECKERT HORST DIPL ING
IPC: B62D61/12
Filed: 1989-06-21
Abstract: 2.1 The axle load of the mechanically sprung drive axle of running gear comprising a lift axle can be described by the spring deflection of the suspension spring and the pressure of the lift bellows. A known device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotation position and axial position a distance which forms the axial load signal to be obtained. Because of the signal body with the three-dimensional characteristic diagram the known device constitutes a complex solution, particularly when the lift axle running gear is only operated with rigid axle load participation of the lift axle, i.e. with only fully raised or fully lowered lift axle. 2.2 In order to simplify the known device, particularly for the last-mentioned mode the invention proposes to displace the signal body (22) axially, independently of the spring deflusion, and to replace the three-dimensional characteristic diagram by a two-dimensional contour (21, 33). 2.3 Preferred application area is vehicle technology. <IMAGE>
