Patent DE-3546555-A1 (DE)
Title: Steering aid for motor vehicles
Inventor: BRUST DIETER ING GRAD
IPC: B62D5/04
Filed: 1985-08-22
Abstract: A steering aid for motor vehicles has a drive unit which assists the manual steering, is operated by an electric motor and acts on a linkage part, influencing the steering angle, in a sense appropriate for the manual steering. The drive unit can only be switched on by a speed-dependent switching device at low travelling speeds and can be switched off when a certain travelling speed is exceeded, and the switching on and off of the drive unit can be controlled as a function of the torque applied manually to the steering wheel. Separate gripping points on the steering wheel are arranged such that they can move with respect to the supporting steering-wheel body, in the circumferential direction counter to spring force, and their ends are constructed as electrical contacts which cooperate with counter-contacts at the adjacent points of the steering wheel in such a manner that, when the contacts are closed due to the spring resistance being overcome when a certain torque is exerted on the steering wheel, the drive unit is switched on and, when the contacts are open, it is switched off.
Patent DE-3602050-A1 (DE)
Title: Telescopic kinked drinking straw
Inventor: KITZING INGE
IPC: A47G21/18
Filed: 1986-01-24
Abstract: Normal drinking straws have only a fixed length. It is not possible to drink out of normal large water and drinks bottles with them, since the straw is too short, drops inside, and below a certain level no longer conveys. For virtually every bottle size, therefore, drinking straws of corresponding length would be necessary. This would mean extensive and costly storage. With the telescopic kinked drinking straw this is unnecessary. Since this straw consists of two kinked straws pushed one inside the other, it can be extended to any bottle length by drawing apart, and it conveys the liquid in any position right down to the dregs. The straw is able to remain standing in the bottle until the latter is empty.

Title: Device for holding a workpiece on the spindle of a numerically controlled machine tool
Inventor: HAEUSSLER PETER
IPC: B23B31/00
Filed: 1987-01-21
Abstract: The application describes a device for holding a tool on the spindle of an NC machine tool set up for automatic tool change. Rotating tools for automatic tool change are conventionally provided with steep-taper clamping shanks which are drawn by a clamping device into a correspondingly dimensioned steep-taper location bore of the spindle. The steep-taper clamping is unsatisfactory during some of the machining operations occurring in practice. According to the present application, the steep-taper clamping shanks are modified in some of the tools to the effect that clamping contact occurs between the radial flange adjoining the clamping shank and the end face of the spindle, while the clamping shank is centred by a short cylindrical centring surface in the location bore, and the taper surfaces of the location bore and of the clamping shank are distanced from one another. At their end of smallest diameter, the location bore and the clamping shank are provided with a pre-centring means which facilitates the insertion of the clamping shank into the location bore and prevents canting of the cylindrical centring surfaces.

Title: Portable drilling machine with two drill chucks for simultaneous accommodation of one tool each
Inventor: LUEKE BERNHARD H
IPC: B23B45/00
Filed: 1987-01-28
Abstract: Technical field, problem solving, range of use: The portable drilling machine with two drill chucks can perform all the tasks of a conventional portable drilling machine and in addition produces a very large rationalisation effect if two operations are required at the same time, e.g. pilot drilling and main drilling, pilot drilling and screwing, drilling and counterboring. The second drill chuck is arranged in exact opposition to the first in an imaginary, common axis, all known functions and features of a drilling machine being retained, e.g. clockwise and anticlockwise rotation, drilling, percussion drilling, electronic speed setting, multi-speed transmission. Protection from the tool not used is offered by: 1) a slipped-over canopy, 2) stoppage of the tool, which is ensured by an electric circuit between the displaceable canopy and the release switch for the tool to be used. The portable drilling machine with two drill chucks can be of very compact construction if the motor is accommodated in one part and the transmission in the other part.
