Patent GB-2130729-A (GB)
Title: Electronic compasses
Inventor: MARCHENT BRIAN GERALD
IPC: G01C17/38
Filed: 1983-09-21
Abstract: An electronic compass for vehicles comprises at least two magnetic sensors 13, 14, e.g. in a fluxgate sensor, respectively responsive to orthogonal horizontal components of a magnetic field which includes the earth's magnetic field and a spurious magnetic field associated with the vehicle, for producing electrical signals 17, 18 corresponding to said components, data storage means 37 arranged to store signals from the sensors as the vehicle is rotated through 360 DEG in the horizontal plane during a compass setting cycle, and signal processor means 42 responsive to the sensor signals after the setting cycle has been completed and to the signals stored during the setting cycle, for providing output signals 44 indicative of the bearing of the vehicle, in which the effects of the spurious field are eliminated. Vehicle speed data from 65 and map reference data from 69 can be combined with the bearing signal. The bearing reading can also be compensated for vehicle tilt from the vertical. <IMAGE>

Patent GB-2136519-A (GB)
Title: Method of and device for controlling the distribution of brake force
Inventor: KLEIN HANS-CHRISTOF
IPC: B60T8/26
Filed: 1984-01-11
Abstract: With a view to controlling the distribution of brake force onto the front axle and the rear axle of a vehicle in dependence upon the static and dynamic axle load distribution as well as other sensed variables, sensors (2 to 4, 16 to 19) serve to ascertain the wheels' rotational behaviour at the front axle (VR) and at the rear axle (HR) as well as, if necessary, the translational deceleration of the vehicle, and, from this data, the brake slip ( lambda ) at the front and at the rear wheels or measured values that are proportional to the brake slip are determined. After the electronic combination and processing of these signals, the brake force distribution is controlled to provide brake slip at the rear wheels of 70 to 100% that of the front wheels by setting a ratio of actual braking force to dynamic axle load (fH) at the rear wheels to amount to from 80 to 100%, of that (fV) at the front wheels by modulation of braking pressure at the rear wheels. The rear braking pressure is increased in steps by successive signal pulses to the electrovalve 13 (Fig. 6) to provide front and rear brake pressure, PVR and PHR characteristics as in Figs. 3 and 4 for respectively a front disc/rear drum brake system and a system with similar front and rear brakes. <IMAGE>

Title: Two-component dispensing device
Inventor: OBRIST-ANGEHRN GERHARD
IPC: B65D83/14
Filed: 1984-08-16
Abstract: An inner container having a dispensing valve is situated within a flexible sack which in turn is situated within an outer container having a cover and a dispensing valve. The sack contains one package component and the inner container contains the other package component and a propellant. A further propellant is situated outside of the sack within the outer container. The inner dispensing valve is constructed as a dosage valve and issues into the interior of the outer dispensing valve. The latter is kinematically coupled with the inner dispensing valve and possesses a blocking system which blocks its interior relative to the interior of the sack when the outer dispensing valve is open. The particular construction and the flow-related coupling of both dispensing valves permits a defined dosed dispensing of both package components with a defined mixture ratio.

Title: Fused silica envelope for discharge lamp
Inventor: TAKEMURA TETSU
IPC: H01J61/35
Filed: 1986-06-05
Abstract: A fused silica envelope for use in a discharge lamp is provided with TiO2 at its inner surface to filter out the ozone-producing UV radiation of wavelength less than 200 nm, wherein the Ti concentration in a range of 1  mu m-10  mu m from the inner surface of the wall of the envelope is 0.5%-7% in terms of TiO2, and the product of the overall average Ti concentration and the depth of penetration of the TiO2 from the inner surface of the wall of the envelope ranges from 3.7%  mu m to 42%  mu m. A layer of TiO2 0.1-1 mu m thick may first be formed on the inner wall of the envelope by coating with titanium tetraethoxide mixed with ethanol and acetic acid, and heating, and thereafter the TiO2 is diffused into the envelope by baking at at least 1720 DEG C. Alternatively, the envelope may be coated with a liquid mixture of titanium alcoholate and silicon alcoholate which is dried and then baked to form an amorphous SiO2 layer containing TiO2 appropriately dispersed therein.   <IMAGE>

Title: Blade for wind turbine
Inventor: SOMERVILLE WILLIAM MURRAY
IPC: F03D1/06
Filed: 1987-01-23
Abstract: The starting characteristic of wind turbines in light winds is improved by providing the turbine with blades 10 each having a primary aerofoil 12 on the leading edge of which is mounted a secondary aerofoil 14. The secondary aerofoil 14 is mounted for movement between an operative position in which it is spaced from the primary aerofoil 12 whereby air can flow between the two aerofoils and an inoperative position in which it lies against and substantially conforms to the leading edge of the primary aerofoil 12. The secondary aerofoil 14 is resiliently biased towards its operative position and is movable against the bias towards its inoperative position by centrifugal forces. In use, the flow of air between the two aerofoils creates a low pressure region at the trailing edge of the secondary aerofoil 14 thereby inducing flow over the secondary aerofoil 14 to create aero-dynamic lifting forces which tend to turn the rotor. The secondary aerofoil may be located only between 50% and 100% (and preferably only between 60%-90%) of the radius of the primary aerofoil (measured from the blade root). The blade can form either part of a rotor which rotates about a horizontal axis or part of a rotor which rotates about a vertical axis. If the turbine has two blades, means may be provided for synchronising movement of the secondary aerofoils. <IMAGE>

Title: Torsional vibration damper with spring holder
Inventor: GROSSPIETSCH WOLFGANG
IPC: F16F15/123
Filed: 1987-06-02
Abstract: The invention relates to the configuration of supports 14, 15 for helical springs 12 in torsional vibration dampers. The spring supports 14, 15 according to the invention are equipped with extensions directed in the circumferential direction, which are configured in the shape of partial cylinders open radially towards the inside. These extensions have, in the circumferential direction, a development equal to 25 to 50% of the longitudinal development of the helical spring 12 compressed to the maximum rotational torque. By virtue of this configuration of the spring supports 14, 15 the helical spring 12 is supported by the extensions even at high speed. By choosing a suitable material for the spring supports 14, 15 it is thus possible to reduce the wear in the contact region of the helical springs and the windows, even for torsional vibration dampers subjected to high stresses. <IMAGE>
