Patent DE-3843841-A1 (DE)
Title: Laser welding process
Inventor: BEYER ECKHARD DR ING
IPC: B23K26/24
Filed: 1988-12-24
Abstract: Laser welding process in which the laser beam (10) produces a melting zone in the workpiece during welding, which melting zone has a vapour capillary in it which is open at least towards the beam source. In order to improve the process in such a way that phenomena disturbing the welding operation do not form in the melting zone, the procedure is to apply the laser beam at an inclination producing an essentially vertical melting front and directed against the relative beam feed direction. At lower welding speeds but under extreme conditions, e.g. when lap welding coated plates, the laser beam is inclined in the other direction in order to produce a vapour capillary opened wide in the direction of the impinging beam.
Patent DE-3844068-A1 (DE)
Title: Brake system
Inventor: SIEGEL HEINZ ING GRAD
IPC: B60T8/48
Filed: 1988-12-28
Abstract: In a brake system with a brake master cylinder designed as electro-hydraulic booster, the said cylinder is connected by way of a piston rod to a brake pedal. The piston rod acts on a master cylinder piston, by way of which a brake chamber can in turn be subjected to brake pressure. As a result brake fluid passes by way of brake lines to corresponding wheel brake cylinders. A servo piston chamber, which is connected by way of a control element to a device for the supply of servo brake fluid, is also assigned to the master cylinder piston. This control element is controlled by means of a regulator. The regulator modulates the control deviation which is derived from the set value, which is formed by the piston rod travel sensor with control unit connected on the output side, and the actual value which comes from the travel sensor of the master cylinder piston. As a function of the rod travel, its first and possibly its second time derivative, the control unit connected to the piston rod travel sensor on the output side, by means of a set of characteristic curves, generates settings which are intended to move the master cylinder piston according to the braking behaviour of the driver. In addition the brake pressure feed back to the piston rod is derived and converted from the travel sensor signal of the piston rod sensor by means of a set of characteristic curves, so that the driver can, on the one hand, slowly and deliberately adjust the pressure non-reactively until the brake pressure feed back to the driver's foot automatically occurs with rising pressure, that is corresponding rod travel, and ...

Patent DE-3909713-A1 (DE)
Title: Multiplication circuit
Inventor: TSUJIHASHI YOSHIKI
IPC: G06F7/52
Filed: 1989-03-23
Abstract: The multiplication circuit according to the invention is in such a form that the intermediate sums of partial products are divided into a group of lower positions and a group of higher positions, and that the operations to obtain the products of only the group of lower positions of the intermediate sums which have already been determined are executed in parallel with the processing to obtain the group of higher positions of the intermediate sums, to obtain the higher products subsequently, taking into account the fact that the intermediate sums of the partial products are determined sequentially from the lower positions to the higher positions. On the basis of such an arrangement, the operations to obtain the group of higher positions of the intermediate sums can be executed in parallel with the operations to obtain the products of the group of lower positions of the intermediate sums which have already been determined, and the higher products are determined subsequently. For this reason, the times which are required to execute the operations of the earlier stage can be made to conform better to the times which are required to execute the operations of the later stage. <IMAGE>

Patent DE-3930265-A1 (DE)
Inventor: DEUSSEN JOSEF
IPC: B22D11/05
Filed: 1989-09-11
Abstract: In the case of continuous casting moulds with two broad-side walls, which are arranged opposite one another on supporting frames in such a way that their shape gives a funnel-shaped free space and between which narrow-side walls adjustable relative to one another for the purpose of adjusting the format width are firmly clamped, mechanical clamping elements in operative connection with hydraulic cylinders being provided for clamping the narrow-side walls, the disassembly of the entire mould after a break-out or overflow and the cleaning of the narrow- and broad-side walls is relatively difficult due to the small opening width of the broad-side walls. This is particularly true for the maintenance of the mould and for the installation and removal of the narrow- and broad-side walls with their supporting elements. These difficulties are eliminated in a simple manner according to the invention by virtue of the fact that the supporting frames (1, 2) with their broad-side walls (9) are arranged in such a way in the continuous casting mould and connected in such a way to the clamping elements (7, 8) that they can be adjusted both towards one another and away from one another. In this way, it is possible for the supporting frames with their broad-side walls to be spread apart to such an extent that they are accessible from both sides, especially in the region of the narrow-side walls and can be cleaned, maintained and exchanged very easily. In particular, following a break-out or overflow the complete mould can be lifted away upwards over the funnel-shaped strand end solidified in the mould.

Patent DE-3934307-A1 (DE)
Inventor: SEITZ DIETER
IPC: B60T8/1764
Filed: 1989-10-13
Abstract: In a process for controlling the braking pressure in an antilock braking system of a vehicle with front and rear wheels, the rotational speeds of braked wheels are measured and, if threshold values of the rotational speed or rotational acceleration are exceeded, the braking pressure in the correponding wheel is reduced or at least maintained constant. If there is no danger of any rear wheel being locked, but the braking pressure on at least one front wheel is maintained constant, the braking pressure on the rear wheels is also maintained constant, at least temporarily. If the braking pressure in at least one front wheel is reduced and there is no danger of any rear wheel locking, the braking pressure in the rear wheels is built-up very slowly, in particular in a pulsed manner.
