Title: T-joint weld between elongated components using flexible interlayer between abutting faces
Inventor: BACH FRIEDRICH-WILHELM PROF DR
IPC: B23K20/16
Filed: 1996-10-10
Abstract: Elongated components (1,2) forming a T-joint are welded together using an interlayer (8) sealing against the flange plate (1) and of a material that is flexible along its length and elastic or elasto-plastic through its thickness, expanding and hardening under heat. The weld is made from the side of the flange remote from the web plate (2), penetrating into the middle of the end face of the web. The flexible material is melted by welding and floats out as slag, while the unmelted material expands and seals the air gap either side of the weld. Preferably, the parts are tack-welded together by making blind holes from the side remote from the angle regions of the components, using a plasma-arc cutter, and filling them up by MIG/MAG welding

Patent DE-19738947-A1 (DE)
Title: Braking force distribution control device with ABS for motor vehicle
Inventor: HARA MASAHIRO
IPC: B60T8/1766
Filed: 1997-09-05
Abstract: The brake control for the vehicle reduces the rear wheel brake pressure when set conditions are satisfied; when the wheel slip of the rear wheels exceeds that of the front wheels by a set value, with the vehicle retardation above a set value. A hydraulic (oil) circuit (70) is designed to provide ABS for suppressing any wheel-slip during braking, by increasing or reducing the brake oil pressure, with overall control via an electronic control unit (60). This brake pressure control for the rear wheels is inhibited if the transmission is set for all wheel drive, irrespective of the wheel slip conditions. An alternate control mode can be used by raising the reference values for rear brake pressure reduction when the all wheel drive is selected. During all wheel drive a locking control is applied to the central differential if wheel slip occurs.
Patent DE-19740307-A1 (DE)
Title: Loom control
Inventor: LOEHR HEINZ PETER
IPC: G05B19/4093
Filed: 1997-09-13
Abstract: The control system is for one or more looms (2-4), each with drives (9-11) with rotary speed control. A central memory (15) contains data on the yarns being woven. At least one computer (16) calculates the maximum permissible working speeds of the looms and/or the maximum permissible rotary speeds of the loom drives. The separate controls (6-8), at each loom, set the loom working speeds or the loom drive speeds according to signals from the computer. A single memory services one or more looms, with a direct access to it for all the looms or their loom controls, or access to the central computer through the memory. The loom controls have a frequency converter to set the loom drive speeds. The data contains information specific to the yarns being woven, to give maximum speeds in relation to the widths of the woven fabrics. The central computer transmits signals to the looms containing maximum speed limits. At least some of the looms each have a separate computer, taking yarn related data from the central memory, to set the loom drive speeds according to the yarn type and weaving width. The loom working speed is reduced to the limit for the yarn data, when the yarn data demands a slower speed than the normal loom working. The yarn data also contain parameters such as the required time run of the braking forces at the yarn brakes, or loom speeds for part pattern repeats. Where the woven fabric has wefts of different yarns, with different yarn data, the loom speed is switched to a higher rate as soon as a direct sequence of a number of wefts have been inserted using a weft material which permits a higher working speed, and preferably after more than 20 weft insertions.
