Title: Material for bridge joints and/or for repairing the surfacing of roads and other load-bearing surfaces
Inventor: MCINTOSH JAMES
IPC: E01C5/12
Filed: 1996-06-21
Abstract: A material for repairing cracks or potholes in roads or other load-bearing surfaces or for forming a bridge joint comprises wood chips covered with a bitumen. In one embodiment a hot bitumen/wood chips mixture is applied to a surface to be repaired. In other embodiments the bitumen is applied to a surface or mould, to which a layer of reinforcing fibres may have been applied, chips are then applied and then further bitumen is applied. The sheet formed in the mould may then be used eg to repair a crack in a road.
Patent GB-2304017-A (GB)
Title: Imaging apparatus
Inventor: MORCOM CHRISTOPHER JOHN
IPC: H04N5/353
Filed: 1996-07-12
Abstract: Imaging apparatus for use in intra-oral dental applications, is comprised of a solid state imager 3, which is continually clocked during a wait period prior to irradiation from an X-ray source 1. A CCD signal is compared with a threshold at comparator 7 to analyse radiation status of the X-ray source 1. This signal changes rapidly and the threshold conditions are varied with ambient conditions and temperature to allow for the increase of dark current with temperature. This permits the CCD trigger threshold for image acquisition to be relatively low whilst minimising the risk of false triggering.
Patent GB-2316291-A (GB)
Title: Loading rack ovens
Inventor: MCSTRAFICK PAUL
IPC: A21B1/44
Filed: 1996-08-16
Abstract: A rack assembly is provided for use with a rack oven, the rack assembly comprising a first rack insertable into the rack oven 26 to remain in the oven during a baking process, and a second rack, insertable into the rack oven temporarily to mate with the first rack such that products to be baked can readily be transferred from the second rack to the first rack. The invention enables baking to be carried out with greater safety. With known ovens, a single rack has to be removed from the oven after baking, and because it has remained in the oven during the baking process, it is very hot. There is therefore a risk that oven operatives could come into contact with the hot racks and receive burns. With the invention, the products to be baked are transported into the oven, and removed from the oven, on the second rack, which never gets heated to a dangerous temperature.

Title: A non volatile semiconductor memory device and method of manufacturing the same
Inventor: MATSUKI TAKEO
IPC: H01L27/115
Filed: 1997-05-14
Abstract: A method of manufacturing a nonvolatile semiconductor memory device comprises the steps of forming a ferroelectric capacitor 16,17,18 on a substrate having a transistor 13,14,15 forming a first dielectric film 20 on the ferroelectric capacitor, and depositing a second dielectric film 21 of silicon oxide on the first dielectric film by a CVD process using tetraethylorthosilicate as a source gas and ozone as an oxidising agent, preferably at a temperature between 350 and 500{C. The first dielectric film 20, which may be siliconoxide, silicon nitride or spin-on glass, prevents hydrogen and water from being introduced from the ferroelectric film of the ferroelectric capacitor during and after the CVD process, thereby improving polarization, leakage current and dielectric breakdown characteristics of the ferroelectric capacitor.

This arrangement allows the system control unit 100 to automatically segment the bus or to configure any of the multiple terminal apparatus units 200 1 - 200 n , without requiring physical access to the units.
Patent GB-2318685-A (GB)
Title: MOS gated device with self aligned cells
Inventor: KINZER DANIEL M
IPC: H01L29/423
Filed: 1997-10-24
Abstract: An MOS-gated power semiconductor device is formed by a process in which a self-aligned device cell is formed, without any critical alignments thereby allowing the cell density to be increased. A sidewall spacer 62 is used to mask the etching of a depression in the silicon to reduce the number of critical mask alignment steps. An optional selectively formed metal connects the polysilicon layer to the P+ and N+ diffusion regions. The sidewall spacer, in combination with the selectively formed metal, prevents impurities from diffusing to the parasitic DMOS channels and inverting them to cause leakage. A termination structure may also be formed by this process.

Title: Mask preparation method including critical dimension test forming means
Inventor: THOMPSON JAMES
IPC: G03F1/00
Filed: 1998-08-20
Abstract: The method comprises forming alignment areas 20 in a field 3 defined by a mask in a corresponding layer of an integrated circuit wafer to allow determination of the orientation of the wafer in a measuring apparatus. Each of the identical alignment areas 20 is formed adjacent to but offset from the origin 12 of the corresponding field. Critical dimension test features 31 are formed in each of the fields in corresponding layers at a location spaced from the alignment areas and the origin. The location at which the alignment areas are to be formed in each field are identified with respect to the origin. The locations at which the critical dimension test features are to be formed are identified with respect to the location of the alignment areas or the location of the origin. This allows reduction in the amount of co-ordinate data to be entered into measuring apparatus.

Title: Cutting element for rock bit
Inventor: ANDERSON NATHAN R
IPC: E21B17/10
Filed: 1999-02-12
Abstract: A cutting element or insert for a rock drilling bit comprises a cylindrical grip section (10) from which extends a convex protrusion (12) and a layer of ultra hard material (30) is formed over the protrusion. A critical contact region or zone (74), which is the portion of an insert closest to a hole wall while drilling, is defined on the insert. This region is most liable to cracking due to stresses during drilling. Measured from a central axis (32) the critical zone is located not lees than a first angle (72) of around 20‹ and not greater than a second angle (73) of around 80‹. Inside this region the ultra hard layer, generally polycrystalline diamond, is thicker than outside to reduce cracking or delamination. Figure 1 illustrates an insert with a protrusion and ultra hard layer which are axisymmetric. Further embodiments have axisymmetric or non-axisymmetric protrusions and axisymmetric or non-axisymmetric ultra hard layers. One or more transition layers may be placed between a protrusion and an ultra hard layer.

This arrangement ensures that the interlocking buckle must be connected to the vehicle mounted tongue before the adjustable tongue can be released for connection with the vehicle mounted buckle.
Patent GB-994712-A (GB)
Abstract: 994,712. Spark ignition systems. ROLLSROYCE Ltd. Oct. 15, 1964, No. 20915/62. Heading F1B. An ignition system comprises first and second spark generating circuits, the first circuit being associated with the second circuit via delay circuit means so that discharge of the first circuit causes the second circuit to discharge between 1 and 40 milliseconds thereafter. In Fig. 2 the first circuit comprises a condenser 9, charged from a H.T. source 14 through a rectifier 8, and a low pressure gas discharge tube 10 while the second circuit comprises a larger capacity condenser 12, charged through rectifiers 8, 11, in series, and a gas discharge tube 13. The two circuits are connected to a common point 17 leading to the spark plug 18 and are interconnected through a transformer 33 and a delay circuit 22. In operation, the condensers 9, 12, charge until the breakdown voltage of tube 10 is reached, when condenser 9 discharges therethrough and through the primary of transformer 23 to produce a spark at igniter 18 which displaces fuel from the electrodes thereof. The pulse produced in the secondary of transformer 23 produces, after a delay produced by circuit 22, a voltage pulse on an electrode 24 which renders the tube 13 conductive and allows condenser 12 to discharge to produce a second spark at igniter 18, the production of which is facilitated by the removal of fuel from the electrodes by the first spark. In a modification Fig. 3 (not shown) the first circuit includes a pair of condensers in cascade and in a further modification the separate delay circuit 22 is omitted, sufficient delay being produced by the transformer 23.
