Title: Assembly for the transient marking of documents
Inventor: SARGENT HERBERT LOUIS FREDERIC
IPC: B43L1/00
Filed: 1994-08-18
Abstract: An assembly for the transient marking of documents eg crossword puzzles or maps, comprises an upper flexible transparent sheet 1 that can be written on, and a lower sheet 2 being either integral or otherwise attached thereto alone one edge. An erasable, water-based pen 8 is used to write on the upper sheet 1. In use a document eg a folded newspaper, is placed between the sheets so as to be held frictionally therein such that the required text can be overwritten. The edges of both sheets may include notches (4a, 4b and 5a, 5b Fig 3) for receiving elastic bands 6, 7 so as to retain the pen 8 during non use. Alternatively the pen may be retained by a flexible clip arranged along one edge of the transparent sheet 1. The eraser can either be a rubbery eraser 10 or a tampon soaked with an oxidising/bleaching agent. <IMAGE>

Title: A system and method for skip-sector mapping in a data recording disk drive
Inventor: DOBBEK JEFF JAY
IPC: G06F3/06
Filed: 1994-12-16
Abstract: A data recording disk drive includes a system and method for mapping around skip sectors, both bad sectors and spare sectors. A received logical block address 904 is converted to a corresponding physical block address by mapping through a set of tables 906, 908, 910. A first table 906 includes entries for virtual tracks which group together LBAs having shared high order bits. A second table 908 contains entries for the skip sectors. The high order bits of a given LBA are used to select an entry in the first table, which entry is an index into the second table. Starting from the index point, the second table is searched, using the low order bits of the LBA, for a skip sector beyond the LBA value. Once the appropriate skip sector is found, the index of this skip sector within the second table is added to the LBA to compute the PBA. The PBA is then mapped to a zone, cylinder, head, sector location on the disk drive. The mapping system reduces the total storage required to convert LBAs to ZCHS values and improves the performance of the conversion process. Additional features include a third table 910 for distinguishing bad sectors from spare sectors, schema for re-mapping spare sectors to substitute for data sectors which fail during use, and overlap between the LBA high order and low order bits to further improve performance. <IMAGE>

Title: Isolated multiple grating system for filtering
Inventor: LI LUKSUN
IPC: G02B6/34
Filed: 1996-12-30
Abstract: The present invention provides a fibre optic filtering device including, in sequence from the input of the device, a primary grating (2), an optical isolator (4) and a secondary grating (6) wherein the optical isolator only transmits light in the direction from the primary grating to the secondary grating. This allows high quality specifications to be achieved both in reflection and transmission, something which cannot as yet be achieved with a single grating. One application of such a filter is in high density wavelength division multiplexed systems, where the ability to separate closely spaced wavelengths with a high degree of cross-talk suppression is required. An add/drop multiplexer comprising the present invention placed between two circulators is disclosed (figure 8). The secondary grating (6) may consist of a sub-secondary grating and a tertiary grating. The gratings may be amplitude profile modified gratings or chirped gratings.
Patent GB-2313015-A (GB)
Title: Infrared microscopes
Inventor: TAKAGI NOBUO
IPC: G01N21/35
Filed: 1997-05-09
Abstract: Before a measurement for an infrared analysis of a sample 16 is performed, a measurement area of the sample 16 is set. In the measurement area setting mode, a camera 28 captures an image of the whole sample 16, and the image is shown on a display 25. An image of an aperture 22 is superimposed on the image of the sample 16 in the display 25. When an operator uses a mouse 27 connected to a controller 24 of the infrared microscope to change the width of the image of the aperture 22 on the display 25, an aperture signal generator in the controller 24 generates an aperture signal corresponding to the width of the aperture image. An aperture image signal generator in the controller 24 receives the aperture signal and generates an aperture image signal having that width. Thus the image of the sample 16 superimposed on the image of the aperture 22 in the display 25 changes accordingly, by which the operator confirms the measurement area, i.e. the position and width of the aperture 22, in the sample 16.

Title: Optical data communications receiver
Inventor: HEWINSON JOHN
IPC: H04B10/69
Filed: 1997-08-30
Abstract: Optical data receiving apparatus comprises a photo detector 1 which generates electrical pulse signals representative of pulses of light received by said photo detector. A pulse stretcher 4 coupled to the photo detector 1 receives the electrical pulses and selectively increases the length of the electrical pulses to a minimum predetermined temporal length. A threshold generator 5 generates a detection threshold equal to the average amplitude of the electrical pulse signals received from the photo detector (1) multiplied by a predetermined scaling factor. Comparator 6 receives on a first input the output of pulse enhancer 4 and on a second input to the output of amplitude scaler 5 and generates an output signal pulse when the stretched pulse signals have an amplitude which is greater than the detection threshold. This facilitates interoperability of systems which use a different pulse length and/or amplitude.

Title: Fractional distillation of fuel and variable supply of fuel fractions for an internal combustion engine
Inventor: MA THOMAS TSOI HEI
IPC: F02M31/18
Filed: 1997-10-09
Abstract: An i.c. petrol engine having a fuel tank, a distillation unit 30, 50, 52 for producing at least two fuel flows of different volatility characterised in that an engine management system 60 separately meters the streams of fuel to the engine and adjusts the relative usage rates of each stream depending on the rates they are produced and thus providing stratification of the charge. Fuel is supplied by a fuel rail 34 and returned to boiler tank 30 by pressure relief valve 36 and rail 38. Here fuel is dripped over a heat exchanger 40 and fractions with a boiling point below 100‹C vaporise and pass through canister 42, compressor 50, where they are compressed to 10 bar, and into pressurised storage reservoir 52 where they are cooled to 40‹C. Fractions with boiling points in the range 40-100‹C condense and are stored as a liquid while fractions with boiling points below 40‹C remain as vapour. The amount of fuel vaporised is dependent on throttle 14 which will draw more fuel through the distillation unit when it is wide open and draw less fuel when less open. Thus more light fraction volatile fuels are used as they are produced under wide open throttle conditions which is when they are required most and less are used and produced under steady operation conditions when heavier fraction high octane fuel is needed.

Title: Diesel engine emission control
Inventor: ITOYAMA HIROYUKI
IPC: F02D41/00
Filed: 1997-11-25
Abstract: An exhaust gas recirculation (EGR) control system for a diesel engine 10 compares at 86 the actual EGR performance (Qac), calculated at 84 in terms of air charge entering a cylinder, with normal EGR performance (Qacf) derived at 82 from engine speed and look-up tables. If the result is outside a predetermined window defined at 88, the performance is abnormal and the amount of injected fuel Qsol is constrained at 72 to a lower maximum value than is the case under normal conditions. At the same time, at 80, the EGR valve command from 76 is reset to zero (closed) and the throttle valve command from 78 is reset to fully open. Smoke emissions are thus reduced.

IPC: E21B37/00
Filed: 1998-10-15
Abstract: An apparatus and method particularly suited for wireline operation is described for removing sand 14 and other debris from a wellbore. A housing 10 is lowered into the wellbore 12 until the housing is proximate to the sand, a valve 20 is opened to permit entry of the sand into a chamber 18. The housing can be raised to the wellbore surface so that the sand can be removed from the chamber. In one embodiment of the invention, figure 4, the housing has a first chamber 38, and a second chamber 42, each having a floating piston 40 and 44 respectively. A liquid 50 is initially retained within the first chamber and is pressurized as the housing is lowered into the wellbore. Activation of a valve 54 and differential pressures acting across the first piston moves the liquid into the second chamber and draws the sand into the first chamber through flapper valve 52.
