Title: Water saving device for domestic hot water system
Inventor: TWINE ROBIN
IPC: F24D17/00
Filed: 1994-06-28
Abstract: A domestic hot water system supplying a tap 12 is provided with a water saving device 14. When the hot tap is turned on, a valve 20 in the device closes so that cooled water in pipe 10 bypasses the tap and is recirculated through return pipe 16.

IPC: G01S13/931
Filed: 1994-07-15
Abstract: A safety system for a vehicle comprises a controller which operably determines the safe stopping distance of the vehicle at a given velocity if its brakes were applied, means (e.g. radar) for generating a signal representative of true velocity of the vehicle which is operably communicated to the controller, a proximity sensor which operably produces a signal representative of the distance of separation of a trailing vehicle which signal is operably communicated to the controller, the controller being operable to determine if the trailing vehicle is within the safe stopping distance in which case the controller actuates an output device to provide a warning to the driver of the trailing vehicle. Selectively inflatable groups of airbags are deployed around the exterior of the vehicle. Different bags in a given group will rupture at different pressures. The anti-lock feature of the vehicle braking system may be automatically disabled at low speeds. Foam may be automatically sprayed when an accident is likely. Transmitter-receiver radar antennas disclosed use two wedges or horns which taper in only one transverse dimension.

Title: Dual concentric string high pressure riser
Inventor: GONZALEZ ROMULO
IPC: E21B7/128
Filed: 1994-12-20
Abstract: A dual string high pressure riser system is disclosed for use in drilling a deep water well through a subsea wellhead. An outer riser (12) extends from the surface and sealingly engages the wellhead (16), and an inner riser (14) extends from the surface downwardly, concentrically through the outer riser to communicate with the well. A surface BOP (20) provides well control at the top of the dual high pressure riser. In another aspect of the present invention, a method is disclosed for conducting deep water drilling operations in which a surface BOP and a lightweight outer riser are installed in communication with a subsea wellhead and a first interval is drilled through the outer riser. Casing is run through the outer riser into the first interval, cemented within the borehole and sealed at wellhead. As drilling proceeds toward subterranean intervals at which high pressure might be encountered, an inner riser is deployed concentrically within the outer riser, engaging to the wellhead at its lower end and communicating with the surface facilities through the BOP at the upper end. Subsequent intervals are drilled through the inner riser.

Title: Detecting unwanted substances in textile fibres from opened bales
Inventor: SCHLICHTER STEFAN
IPC: D01G31/00
Filed: 1997-08-07
Abstract: To detect unwanted substances in textile fibres flowing in air duct 9 a from opened bales to a spinning preparation machine, cameras 15, 16 make reflected-light and transmitted-light images of the fibres, which images are evaluated electronically. Each camera receives light from sources 17 or 18, and 25 or 26, via mirrors 18 or 19. Image evaluating device 32 determines the degree of brightness and/or the colour of the fibres, and the degree of brightness of unwanted substances. Then continuously measured values of fibre brightness and/or fibre colour, and of brightness of unwanted substances, are compared with at least one specifiable limiting value. When a value is exceeded, a display is initiated and/or flap 29 opened to remove unwanted substances.

Patent GB-976983-A (GB)
Abstract: 976,983. Measuring displacement electrically. SPERRY GYROSCOPE CO. Ltd. April 28, 1961 [May 3, 1960], No. 15472/60. Heading G1N. [Also in Division H1] The armature of a differential transformer closes the magnetic circuit in such a way that the magnetic flux couples with a variable number of turns on each of two secondary windings connected in series opposition, whereby the secondary output voltage indicates in magnitude and phasesense the extent and direction of displacement of the armature from a symmetrical location. As shown (Fig. 2) for measuring angular rotation, the transformer secondary windings 16 are located in slots 15 between skewed teeth 14 on each of two ring-shaped magnetic members 12, 13, each with a gap, the two rings being separated by a non-magnetic ring 10, and magnetically linked by a U- shaped member 18 touching ring 12 at 21 and ring 13 at 22, carrying an A.C. -energized coil 23. Inside the rings is an armature 6 comprising a magnetic insert 5 on a shaft 7. The flux produced by the energized coil 23 thus passes through member 18, part of coil 16 on ring 13, the armature 5, part of coil 16 on ring 12, and back to member 18. Initially equal lengths of the two coils 16 are in the magnetic circuit giving no series resultant output voltage, but as shaft 7 is rotated the output voltage indicates by its magnitude and phase-sense the magnitude and direction of the rotation. Other forms of the transducer for measuring angular displacement are given (Figs. 7, 8, not shown), and an embodiment for measuring linear displacement (Figs. 4, 5, 6, not shown).

Title: Detecting a face-like region
Inventor: HONG QI HE
IPC: G06K9/00
Filed: 1998-01-23
Abstract: In a method for detecting face-like regions in a colour image, e.g. from a video camera, the saturation component is derived 21 from a colour image 20 e.g. by conversion from the RGB format. The spatial resolution of the saturation-component image is reduced 22 by spatial averaging so that the image of a face is represented by a small number of reduced resolution pixels e.g. 3 in each dimension. The reduced resolution saturation image is then tested 23 to find regions which are of substantially uniform saturation and of a predetermined size and shape which are surrounded by a region of substantially different saturation.
