Title: Antireversion agent for inserts used in runflat tires
Inventor: MINER JENNIFER ANN
IPC: C08K5/3415
Filed: 2001-03-30
Abstract: Runflat tires are generally made by including a stiff insert in the sidewall thereof. This insert should be as stiff as possible to help support the weight of the vehicle to which the tire is mounted in situations where there is a loss of air pressure. During periods of operation after loss of air pressure the stiff insert carries most of the load on the tire which leads to the generation of heat. Heat build-up can then lead to thermal degradation in the insert. A reduction in crosslink density and a change in the distribution of crosslink types is the result of this thermal degradation. This invention is based upon the discovery that thermal degradation in the inserts of runflat tires can be inhibited by including a bis-citraconimido compound therein as an antireversion agent. This invention more specifically discloses a pneumatic tire having at least one insert to provide the tire with runflat capability wherein the insert is comprised of a rubbery polymer and antireversion agent, such as pentaerythritol triacrylate, pentaerythritol tetraacrylate, N-N'-m phenylenediamaleimide, hexamethylene bis-thiosulfate disodium salt dihydrate, mixtures of zinc salts of aliphatic and aromatic carboxylic acids, alkylphenol disulfide, dioctylthiophosphate, caprolactam disulfide, 4-morpholinyl-2-benzothiazole disulfide, thiocarbamyl sulfenamide, 4,4'-dithiodimorpholine, mixtures of N-N'-m phenylenediamaleimide and tetrabenzylthiuram disulfide, and sulfur containing organosilicon compounds.

Title: Laser
Inventor: KARRAI KHALED
IPC: H01S5/04
Filed: 2001-04-03
Abstract: A laser comprises a chip structure having a surface 38, a first mirror 35 integrated with the chip structure 30 and a semiconductor gain medium 34 arranged in the chip structure between the surface and the first mirror 35. The laser has an optical fibre 50 at the end of which is arranged an integral second mirror 52. The end of the optical fibre is positioned above the surface of the chip structure to form a laser cavity with the semiconductor gain medium and the first mirror. The laser may have a piezoelectric tuning fork (60, Figure 9) attached to the optical fibre in order to vary the distance between the optical fibre and the chip structure. By varying the distance between the optical fibre and the chip structure the cavity length can be altered thereby tuning the laser. The first mirror may be a Bragg mirror having alternating semiconductor layers, alternating dielectric layers or may have multiple dielectric layers. The laser may be electrically or optically pumped. The laser may have a mesa structure 40. The method of tuning a VCSEL is also disclosed. The method may include using a control mechanism to identify a desired optical mode of the laser cavity, and a feedback control mechanism to measure a control parameter. The measured control parameter may be an interaction force between the end of an optical fibre and the surface of a chip structure.

Title: A method of seismic surveying with overlapping shot times
Inventor: JEFFRYES BENJAMIN PETER
IPC: G01V1/00
Filed: 2002-04-06
Abstract: The or each vibrator in a first vibrator group is actuated at time T0, a second vibrator group is actuated at time T1 that satisfies T0 < T1 < T0 + S1 + L where S1 is the sweep time of the first vibrator group and L is the listening time. At least one of the first vibrator group and the second vibrator group comprises at least two vibrators. The first group and the second group of vibrators may be the same group, or they may be different groups. This method enables the time required to complete a seismic survey to be reduced compared to the prior art "simultaneous shooting" and "slip-sweep shooting" techniques. Where the first group and the second group of vibrators are different, the method may further comprise actuating the first vibrator group at time T2, where T1 < T2 < T1 + S2 + L and S2 is the sweep time of the first vibrator group, and then actuating the second vibrator group at time T3 where T2 < T3 < T2 + S1 + L and where T3 - T2   *  T1 - T0. The varying time delay between a shot of the first vibrator group and the corresponding shot of the second vibrator group means that harmonic noise will occur at different times in the shot records so that the noise may be eliminated by appropriately combining the shot records.

Title: Image scanning using a meandering scan path
Inventor: MAGUIRE JAMES EDWARD
IPC: H04N3/30
Filed: 2003-01-17
Abstract: A method of scanning an image using a non-raster meandering scan so that there is unbroken continuity between all the pixels in the image. The scan is built up by the recursive applications of a simple pattern so that any two pixels in the path are physically adjacent ones, the pattern being orientated to achieve connectivity with the preceding and succeeding patterns. Horizontal and vertical scan rates are approximately equal in this method which results in a reduction in bandwidth, storage and compression requirements. The power spectrum of this method does not exhibit the line rate comb, nor does the signal suffer from ghosting due to transmission reflections. This method may also be applied to time series 2D images or 3D images and may also be applied to large screen displays whose deflection high slew rates virtually rule out conventional deflection systems.
