Patent DE-4407116-A1 (DE)
Inventor: BUCK WALTER PROF DR ING
IPC: H01Q7/06
Filed: 1994-03-04
Abstract: A long-wave aerial for insertion into a small radio watch has at least two components (10, 20) contained in the casing (40) of the radio watch enclosing a gap (S) with increased magnetic field intensity (H) between them in which is fitted a coil (30) to bunch the aerial signal which forms a reception oscillator circuit (E) with a capacitor. With the separation of the components acting as an aerial, which may be structural parts of the watch casing, from the coupling coil of the reception oscillator circuit, which belongs to the electronic input stage of the reception circuit, considerable manufacturing advantages are obtained in that both structures can be made separately and optimised. When the radio watch is assembled, it is easy to optimise performance in that the position of the coupling coil can be slightly altered in relation to the two components. As several components are envisaged, it is also possible to use different ferromagnetic materials, and use can be made of this in shaping the magnetic near-field of the aerial structure.

Patent DE-4437300-A1 (DE)
Inventor: BROENNER GUENTER
IPC: F15B11/04
Filed: 1994-10-19
Abstract: A process is disclosed for exactly positioning the tilting outfit (1), in particular the shovel, mounted on the descending lift frame (1) of a movable construction machine, in particular a wheel-mounted loader. Logical circuits (13) co-operate with automatic positioning means (14) so that when the latter are actuated the logical circuits (13) switch a solenoid valve (20) and move the tilting piston (24) of a control valve (25) into a position in which oil fed by a pump (16), in particular a regulated pump, can flow to the tilt ram (6). As the piston rod (7) of the tilt ram (6) is extended, the path covered by the piston rod (7) is measured at several predetermined spots. The first measurement value triggers a signal that causes the logical circuits (13) to activate another solenoid valve (21) or to deactivate at the same time the first solenoid valve (20), placing the tilting piston (24) in a position in which oil flow to the tilt ram (6) is reduced to a predetermined extent. The extension of the piston rod (7) is slowed down and another measurement value triggers another signal that leads the logical circuits (13) to deactivate both solenoid valves (20, 21) or only the second solenoid valve (21), cutting oil flow to the tilt ram (6).
