IPC: D04C1/12
Filed: 1993-03-29
Abstract: A flat cable comprises a series of parallel electrical conductors (1 to 6) each carrying a spiral-wound tape insulation layer (30). The conductors are held together by braiding formed of a plurality of tapes (10 to 22) or fibres interwoven between the conductors. The braiding is preferably of a thermoplastic material which may be heat bonded to the insulation in order to set the cable in a desired shape e.g. for a wiring loom.

Title: Coating of anatase titanium dioxide particles
Inventor: MEINA DOMINIC GERARD
IPC: C09C1/36
Filed: 1993-04-15
Abstract: A process for the preparation of anatase titanium dioxide having a high surface area and suitable as a catalyst support involves forming an aqueous dispersion of titanium dioxide at a pH less than 3 and depositing a first coating of a hydrous oxide of an element c.g. Al, Zr, Si or La) which acts as a rutilisation inhibitor and a second coating of a phosphate on the particles of titanium dioxide.

Title: Lockable handle
Inventor: DOLMAN TERENCE JAMES
IPC: E05B13/10
Filed: 1993-09-20
Abstract: A door or window handle 11 is provided with a locking mechanism in the form of an L-shaped locking member 23 that sits within the handle. One limb 22 of the L-shaped member has a head 24 that can project from the handle in order to lock the handle to a base to prevent relative rotation between the handle and the base. The other limb 25 of the member projects along the under surface of an arm of the handle and can be operated as the arm is gripped to slide the first limb 22 into the arm and so release the mechanism for rotation relative to the base. The base may be connected to the handle by a member (76, Figure 6 not shown) which allows relative rotation between the handle and base but prevents relative axial movement therebetween. <IMAGE>

Patent GB-2280308-A (GB)
Title: Semiconductor optical devices
Inventor: TAKIGUCHI TOHRU
IPC: H01S5/12
Filed: 1994-06-17
Abstract: The device includes a first semiconductor layer 4a, and a diffraction grating 5. The diffraction grating comprises portions of a superlattice layer comprising second semiconductor layers 5a comprising a semiconductor material in which mass transport hardly occurs and third semiconductor layers 5b comprising a different semiconductor material. A fourth semiconductor layer 4b is grown on the diffraction grating by vapor phase deposition. Since the second semiconductor layers in which mass transport hardly occurs are included in the diffraction grating, the shape of the diffraction grating is maintained during the deposition of the fourth semiconductor layer. Therefore, the thickness, amplitude, and pitch of the diffraction grating that determine the optical coupling constant are controlled with high precision. The superlattice layer comprises alternate layers 5a of InGaAs and 5b of InP. The device may be a DFB laser, a waveguide type grating filter or a reflection type grating polariser. Integrated structures comprising a DFB laser diode and a light modulator as well as wavelength tunable DBR and laser diode are also described. <IMAGE>

Patent GB-2307527-A (GB)
Title: Determining a trigger threshold value for an automatic braking operation
Inventor: BRUGGER FRANZ
IPC: B60T8/32
Filed: 1996-10-28
Abstract: In a method for determining a trigger threshold value for an automatic braking operation in which, whenever the actuating speed of the brake pedal exceeds a trigger threshold value, a brake pressure is built up which is greater than the brake pressure corresponding to the position of the brake pedal, the trigger threshold value AS is determining from a prescribed threshold value VS and a vehicle-specific correction value ABW. A standard characteristic is stored for the relationship between the vehicle retardation (aFZG) and pedal travel (sP). During a brake actuation the pedal travel (sPi) and the vehicle retardation (aFZGi) are determined repeatedly, and a value sPiO (at aFGZi=0) is determined for each travel/retardation pair taking account of the standard characteristic curve. A sliding average sPm is calculated from the values sPiO and is used to calculate the vehicle-specific correction value ABW.
Patent GB-2319142-A (GB)
Title: Base site selection in a cellular radio communication system
Inventor: BAR-ON DAVID
IPC: H04W16/26
Filed: 1996-11-05
Abstract: In a cellular radio communications system, the selection of a base site for hand over is determined by the mobile radio according to the rate of change of signal strength received from its serving base site. For low rates of change of RSS, base sites are successively selected from a first list of preferred base sites, starting from top of the list until an appropriate base site is found. When the rate of change is rapid base sites from a second list are selected. The method has particular application to a mobile entering a tunnel 70 having a base site J. A mobile 2 served by cell A, on entering the tunnel experiences a rapid fall 75 in RSS. By selecting from the second list which, unlike the first list, has base site J near the top of the list, the most appropriate base site is rapidly found. Base site J then transmits a third list to the mobile comprising cells A, D and J only so that on exiting the tunnel the most appropriate base site can again be rapidly connected.
Patent GB-2319678-A (GB)
Title: Dimming discharge lamps
Inventor: LIN MING-CHAO
IPC: H05B37/02
Filed: 1996-11-25
Abstract: The high frequency output of an oscillator 39 in an electronic ballast 30 is periodically interrupted (Fig.4) in order to dim a discharge lamp 40. To avoid the prior art use (Fig.1) of additional wiring from a separate dimming level setting device, a dimming level command signal is sent on the AC power line input to the ballast 30 from a power switch 43. The dimming level signal may be produced by operating the power switch 43 so as to interrupt certain cycles or half cycles (Fig.3) of the AC supply to the ballast 30. Changing the dimming level signal causes a logic controller 37 to change the ratio between the ON and OFF periods of the high frequency output of oscillator 39 to vary the lamp brightness.

Title: Timing fuel injection in i.c. engines by sensing rotation of crankshaft and camshaft
Inventor: SCHMIDT LAWRENCE E
IPC: F02D41/34
Filed: 1997-02-14
Abstract: A digital logic circuit 205 receives pulsetrains from a crankshaft rotation sensor 160 and a camshaft rotation sensor 170. The sensing means for each shaft comprises a toothed wheel (155, 165 fig.1) and a magnetic pick-up (160,170). A microprocessor 210 determines which pulsetrain to use for timing the injection (normally that from the crankshaft since its wheel has more closely spaced teeth) and sends a select signal to the digital logic circuit 205 which sends a clock signal having the same frequency as the selected pulsetrain to a programmable timer circuit 215 which also receives the crankshaft and camshaft pulsetrains. The timer circuit samples each pulse and sends a signal indicative of the period of each pulse to the microprocessor 210. The microprocessor 210 delivers an inject request signal to the timer circuit 215 which then sends an inject signal to the appropriate injector. The inventions gives high resolution and redundancy.
