Title: Steering control system for a vehicle with a steered front axle and a steered rear axle
Inventor: LEIBER HEINZ
IPC: B62D7/15
Filed: 1990-05-17
Abstract: The invention is a steering control system which, when a yaw condition is detected, executes an automatic intervention in the steering of the rear axle 38, in order to stabilize the tracking of the vehicle. The steering always takes place in the direction of the vehicle side on which the higher braking torque is generated; this applies also to cornering, irrespective of whether the lower -value is on the inside of the bend or on the outside of the bend and, furthermore, irrespective of whether the vehicle is being braked or accelerated. The system is operated in response to speed signals, ABS/ASR signals and/or torque, brake caliper pressure or brake pressure differences.

IPC: H04N5/44
Filed: 1990-09-11
Abstract: A volume control circuit comprises a voltage controlled amplifier (2) and a control circuit (4) controlling the gain of the amplifier (2). The control circuit is connected to a microphone input (5), picking up the ambient noise in the environment, and has a feedback path (6) from the output of the amplifier (2) with a gain equal to or less than that of the path from the amplifier output (3) via the loudspeaker and air path to the microphone and input (5), so that the influence on the gain of the amplifier (2) of its own output is low or negative, hence avoiding audio feedback, and an increase in ambient noise causes a corresponding increase in the gain of the amplifier (2). <IMAGE>

Abstract: 908,782. Measuring electrically. BARNES CO., W. F. & JOHN. May 28, 1959 [May 28, 1958], No. 18242/59. Class 40 (1). [Also in Group XXII] A positioning indicator comprises, as in Fig. 8, a long tapped primary coil 62 attached e.g. to the bed of a machine tool surrounded by a short secondary coil 100 preferably also tapped and attached for example to a cutting tool. The primary is fed from an A.C. supply, one supply line being connected to two spaced taps, whilst the other line is connected to an intermediate tap. The secondary is connected to a device responsive to the magnitude and phase of the induced voltage and hence the position of the secondary coil relative to the primary coil. Measuring circuit, Fig. 7.-Primary coil 42 has taps 44 spaced at e.g. 1-inch intervals. The two ends of the coil are fed through resistors 54 and 56 from one side of an A.C. supply while the other side of the supply is fed to one of the taps via switch 50. Resistors 54 and 56 are of such a value that the current through the sections of the primary either side of the selected tapping point are the same, irrespective of the tapping point selected. Secondary coil 100 has tapping points, preferably 14, spaced at 0.1- inch intervals and connected to switch 110 and 112 so that any 0.1 inch section of the secondary may be selected to be connected to the primary of matching transformer 118. The secondary of the matching transformer is connected by screened cable 124 to amplifier 126 and indicator 128 and may also be connected to oscilloscope 130. Indicator 128 is sensitive to both amplitude and phase of its input signal. Transducer construction, Fig. 4.-The primary coil is preferably worked on an aluminium former 62 supported by plugs 65 and 70 fitting into the ends and supporting the tube from brackets 66 and 72 attached to the bed of the machine. The tube being spring loaded to the left by spring 84 and positioned by micrometer adjuster 94. The secondary coil is preferably wound on a plastic former and supported by brackets 108 from e.g. a drilling machine head movable relative to the machine table. The invention is preferably used as a coarse position indicator in conjunction with a fine position indicator such as a device available under the (Registered Trade Mark) " Inductosyn."

Title: Timed switching arrangement for lighting
Inventor: JEHLE HERBERT
IPC: H05B37/02
Filed: 1991-01-30
Abstract: Actuation of a push button 2 causes stair well lights 1 to be energised at full intensity for a switching-on period followed by an after glow period during which lights 1 are energised at reduced intensity to act as a warning signal, a further actuation of a push button 2 during the after glow period restoring full intensity for a further switching-on period followed by a further after glow period. A triac 3 is triggered at each zero crossing of a mains supply 10 give the full intensity and at fewer zero crossings during the after glow period. If a push button 2 is actuated during a switching-on period, lights 1 may be turned off immediately or after a delay. An after glow period may also be provided in this case. If, with lights 1 off, a button 2 is operated for less or more than a certain period, the switching-on period will be respectively of a first or a longer, second duration, followed respectively by an after glow period of a third or a longer, fourth duration. The longer switching-on period may alternatively be terminated only by a further operation of a push button. <IMAGE>

Title: Waveguide filter
Inventor: RADCLIFFE CHRISTOPHER JAMES
IPC: H01P1/208
Filed: 1991-03-12
Abstract: A waveguide filter for use in a DBS system operating in dual mode with orthogonal polarization planes. The filter consists of a circular waveguide (1) containing a series of dielectric resonators (7, 9) supported, spaced apart, in a body (4) of low dielectric constant material. The resulting filter is provided with circular waveguide couplings (3) for direct connection to waveguide section. Efficient coupling of the filter to waveguide is achieved by selection of the various parameters: size, shape, spacing of the DR's and the supporting material, and guide dimensions. A dual mode bandpass filter operating at about 12 GHz can thus be achieved at very low cost.

Title: Power mine door system
Inventor: KENNEDY WILLIAM R
IPC: E21F1/10
Filed: 1992-06-25
Abstract: A power mine door system including a door frame 22 to be installed in a mine passageway to define a generally rectangular doorway. A mine door is defined by a pair of generally rectangular door leafs 24, 28 which are hinged on the door frame at opposite sides of the doorway for swinging between an open position to permit passage through the doorway and a closed position in which the door leafs are generally coplanar and close the doorway. The door leafs are so dimensioned that there is a substantial vertical gap between the door leafs when they are closed to accommodate convergence of side walls of the passageway. A relatively wide vertical sealing flap 80 is secured to one of the door leafs for overlapping a face of the other door leaf when the door is closed for covering the gap between the door leafs. A power mechanism for opening and closing the door leafs is operable to control the sequence in which the door leafs close so that the door leaf carrying the sealing flap closes after the other door leaf for ensuring that the sealing flap closes against the face of the other door leaf. <IMAGE>
