Patent GB-2208042-A (GB)
Title: Antenna arrangement
Inventor: BOLLARD DAVID ROOKSBY
IPC: H01Q9/27
Filed: 1987-07-29
Abstract: An antenna arrangement, particularly for broadband radio direction-finding at microwave frequencies, comprises conical antenna means (1, 2) having a longitudinal axis (3) of rotational symmetry, spiral antenna means (4) disposed in a plane perpendicular to the axis (3) and coaxial with the conical antenna means, and plane polarisation filter means (9) having rotational symmetry about the axis (3). From a signal incident thereon, the polarisation filter (9) supplies to both the conical and spiral antennae a plane polarised signal with its plane of polarisation inclined to the axis (3) at a predetermined angle. The spiral antenna means provide a signal whose phase is representative of the disposition, as projected into their plane, of the phase front of the plane polarised signal incident thereon, and the conical antenna means provide a phase reference signal from the same phase centre as the spiral antenna means. As a result, the phase difference is dependent on the angle of the direction of incidence about the axis (3), typically the bearing, but is independent of the angle of the direction of incidence to the axis (3), typically the elevation, and of the plane of polarisation of the incident signal. <IMAGE>

Title: A hydraulic dual-circuit braking system
Inventor: WETZEL GERHARD
IPC: B60T8/46
Filed: 1991-02-22
Abstract: In a hydraulic dual-circuit braking system having an anti-skid system (ABS) and drive-slip control (ASR), a charging valve (43) connects a return pump (29) to the brake fluid tank (18) and when the brake pedal (19) is not depressed a changeover valve (44) and an accumulator connection valve (45) are switched over to charge an accumulator (50) which provides for rapid brake pressure build-up during drive-slip operation in wheel brake cylinders (10) having large volume requirements. The accumulator (50) is automatically switched off by a non-return valve (46) and by a parallellely connected pressure-limiting valve (49) when the pressure in the brake supply circuit exceeds the instantaneous accumulator pressure. A pressure limiting valve (47) with a higher opening pressure than the valve (49) limits the charging of the accumulator. An alternative embodiment has a diagonal brake distribution instead of the front/rear one shown and requires a second changeover valve (44). <IMAGE>
