Title: Organometallic containing mesophase pitches for spinning into pitch carbon fibres
Inventor: ROMINE HUGH E
IPC: D01F9/145
Filed: 1991-12-13
Abstract: A metals containing anisotropic pitch suitable for carbon fiber manufacture is produced by adding a soluble aromatic-organometallic compound to a carbonaceous feedstock which is substantially free of mesophase pitch and the resulting composition is heat soaked to produce an isotropic pitch product containing mesogens and soluble, aromatic-organometallic compounds. The pitch product is solvent fractionated to separate mesogens which contain metals from the organometallic compounds and is then heat-treated. In another method, the carbonaceous feedstock is heat soaked to produce an isotropic pitch product containing mesogens and the organometallic compounds are added to the mesogen containing isotropic pitch product prior to solvent fractionation. Alternatively, the solvent fractionation or separation is conducted under supercritical extraction conditions to produce a metals-containing mesophase pitch. Organometallic compounds may be added to the carbonaceous feedstock either prior to or after the heat soak step. The organometallic compound is preferably macrocyclic and most preferably porphyrin derived.

Title: I c sensor
Inventor: DENYER PETER BRIAN
IPC: H04N3/15
Filed: 1992-03-20
Abstract: An integrated circuit image array sensor is described in which charge sensing circuitry is implemented within a restricted cell pitch and which performs preliminary charge sensing as close as practicable to the cell site. The compact array is realised by incorporating a charge sensing amplifier (20) at the top of each array bit-line (18). Each charge sensing amplifier (20) has two amplification stages (34, 36); the first stage (34) performs preliminary detection of the charge accumulating in a cell (32) in response to incident radiation by converting this to a voltage which is stored capacitively prior to read-out, and the second stage (36) produces the required output. The circuit design is described as realised on CMOS but can be realised in a number of different fabrication technologies.

Title: The reduction of configuration buffet on transport aircraft by flap shroud extension.
Inventor: BRAZIER ROBERT E J
IPC: B64C3/14
Filed: 1992-08-11
Abstract: An arrangement for substantially reducing configuration buffet on a transport aircraft including a wing (1) (Fig 1) having a trailing edge including a spanwise extending shroud (8) and two or more trailing edge flaps (3, 4) (Fig 1) mounted on the wing.

Title: Treating waste water to remove heavy metal ions
Inventor: YUN MYUNG-WHAN
IPC: C02F1/52
Filed: 1994-05-20
Abstract: A method for treating waste water containing heavy metal ions using an extract from acorns and nuts of other trees belonging to the Eagaceae group. Acorns are dried in sunlight at ambient temperature, extracted with water and the acornic acid extract filtered until it becomes colourless. Waste water containing heavy metal ions at low or high concentration is adjusted to pH=8-11.5 by adding NH4OH, Ca(OH)2 or NaOH and the acornic acid extract is added. Ca<++> ions, either on their own or together with other divalent cations, are added to a concentration of 50 ppm to the solution. The solution is agitated for several minutes and the precipitate containing the heavy metal ions is allowed to settle or is removed by filtration to produce treated waste water with reduced levels of heavy metal ions.

Title: Bobbin thread detection device for sewing machines
Inventor: PASSMORE THOMAS ISAAC
IPC: D05B59/02
Filed: 1995-05-18
Abstract: A detecting device which detects bobbin thread within the bobbin case (3) of a sewing machine emits an alarm when the bobbin thread should be replaced and inhibits further machine operation.

Title: Needle valve
Inventor: CRAWFORD KEITH
IPC: F16K31/524
Filed: 1995-08-24
Abstract: A needle valve has a valve stem (2) movable into and out of engagement with a valve seat (36). The valve stem (2) is biased to the closed position by disc springs (18) or other resilient means, and is driven to the open position by rotation of a drive housing (8) screw-threadedly mounted in a fixed housing (5) to compress the springs (18). Rotation of the drive housing (8) in the opposite direction allows the valve stem to re-engage the seat (36) solely under the biassing force of the springs (18). Also disclosed is a needle valve comprising a stem (51) provided with a pair of flow control surfaces (62, 63) which cooperate with respective seats (64, 65). The spindle is coupled to a cam-operated drive housing (58) through a lost-motion connection which includes sets of disc springs (70, 71). The valve is particularly for use in a subsea environment and is under reduced risk of damage resulting from the application of excessive operating force. <IMAGE>

Title: Structural Mounting system
Inventor: HOLMES ERIC
IPC: E06B3/68
Filed: 1994-03-11
Abstract: A structural mounting system for mounting of structural components (14, 15) includes a base section (10) and a cooperating section (11) each of which in use is secured to a respective structural component and which are assembled together. The base section (10) in cross section includes an undercut (21) and the co-operating section (11) in cross section includes a leg (35), having a toe (34) projecting laterally to engage the undercut (21). When the sections (10, 11) are being coupled together the co-operating section is rotated about its longitudinal direction relative to its final position so that lateral movement of the toe (34) to engage beneath the undercut (21) requires the co-operating section to rotate about the longitudinal axis relative to the base section to adopt its final position. Spaced linear restraint points (60, 61) and a rotation restraint point (62) together defining a triangle of points of contact to make the assembly of sections rigid. The sections (10, 11) have co-operating formations (36, 38, 46, 47, 48, 71, 73, 76) which require rotation of the co-operating section (11) relative to the base section (10) in a direction opposite to the direction of rotation to effect engagement of the toe (34) with the undercut (21) during final position. <IMAGE>
