Patent GB-2248935-A (GB)
Title: Surface inspection device
Inventor: YOSHIDA HAJIME
IPC: G06T1/00
Filed: 1991-10-02
Abstract: An object is irradiated, transmission or reflection light therefrom is picked up by a video camera, and an image signal is electronically processed to detect defects on the object. An image signal is extracted whose contrast of light and shade exceeds a preset value, converted into a digital signal, and stored in a memory (Fig. 1A). A histogram (Fig. 1C) of the digital signals in the horizontal or vertical direction of the image is formed, and a filter produces a waveform (Fig. 1D). Parts of the waveform that exceed a preset threshold TH are extracted, and a center line of each extracted part is obtained. A window 6 scans the memory in the vertical direction until it coincides with the center line of the extracted waveform image. A judging circuit decides that there is a defect whenever there are more signal counts than a preset value in the window. Horizontal and vertical histograms may be formed to locate possible flaws without needing to scan the window 6. <IMAGE>

Patent GB-2258972-A (GB)
Title: Restoration of faded colour pictures using an image scanner
Inventor: NUMAKURA TAKASHI
IPC: H04N1/407
Filed: 1992-07-15
Abstract: A faded colour picture original such as a photograph is scanned to produce a colour image signal which indicate the density (DFn) of the pixeis of the original; these values are converted to corresponding light intensity values (Xn). Fading is due to a decrease in the intensity of pixels; all signals for a given colour fade to the same degree, therefore by boosting the intensity of colour pixels (by an amount determined by comparing the intensity of pixels of an unexposed area on the faded film with a corresponding unexposed area on unfaded film) a halftone image identical to the (no longer existing) unfaded original image may be produced. <IMAGE>

Title: Emi shielding pigments, a process for their preparation
Inventor: VOLKER WERNER
IPC: H05K9/00
Filed: 1992-07-20
Abstract: The invention provides new electromagnetic interference (EMI) shielding pigments based on silver coated carrier pigments which have a wider activity spectrum and are more economically available than previously known shielding pigments. The carrier pigments used are platelet shaped, ferro- or ferrimagnetic, Fe-containing, naturally occurring or synthetically produced laminar minerals; the Ag coating amounts to 5 to 25% by weight, based on the carrier pigment. Shielding pigments, which may be prepared by conventional chemical deposition of Ag, may be used for the production of EMI protective coatings and EMI protective films. Preferred carrier pigments are the micaceous iron ores.

Title: Electronic control apparatus
Inventor: VIVERS PETER
IPC: G05B19/042
Filed: 1994-04-27
Abstract: Electronic control apparatus of a kind used in low voltage industrial equipment such as assemblies of motors or circuit breakers. Where an overall controller, eg a programmable logic controller (PLC) controls an array of (eg) motors (M1, M2, M3) by way of respective control units (13, 23, 33) identification or location of selected motors is usually effected by an address stored in the respective control unit. A faulty control unit entails replacement and loss of the location address which has to be re-entered as a skilled operation. The invention provides a separate non-volatile memory (15, 25, 35) for the location address, this memory being physically associated with the particular motor (M1 etc). A replacement control unit (13, 23, 33) is automatically loaded with the location address which was retained. <IMAGE>

Title: Porous sheet for the drum of a stencil printer
Inventor: MORI TOMIYA
IPC: B41M1/12
Filed: 1995-06-14
Abstract: In a stencil printer, a drum has the outer periphery thereof formed by a porous sheet (14) having passages for ink therein. The passages are each configured such that the ink (80) entering an inlet pore (14a) is diverted from a single perpendicular to the drum at least once, and then flows out via at least one of outlet pores (14b). This reduces the amount of ink (80) transferred to the paper (P). The pores of the sheet are sized smaller than perforations (50f) to be formed in a stencil (50). The porous sheet may comprise staggered arrays of fibrous members, which may comprise fibre bundles, fibres with undulating profiles or fibres with protruding fine fibres. Alternatively a sheet of resin or metal or a sintered or foamed sheet may be used. <IMAGE>

Abstract: A fluid-powered centrifugal cleaner 25 (Fig 2) of liquid contaminated with solids, for example, from a back-flush arrangement 23 (Fig 1) associated with a barrier type filter 13 through which liquid is pumped, includes, in addition to the normal shaft mounted rotor 40 through which liquid is passed to separate contaminants centrifugally due to rotor speed, fluid drive means 50 in the form of fluid reaction drive nozzles 53 supplied with pumped liquid from the system as a drive fluid to rotate the rotor at a speed above the minimum to effect centrifugal separation of the contaminants from the back-flushed liquid in the rotor. The spent drive fluid mixes with the cleaned back-flushed liquid in a discharge region 29 and both may be reused in the system. Control valve means 80 permits the rotor to be removed whilst liquid flows in the arrangement, interrupting the supply of drive fluid to the drive nozzles and diverting the contaminated liquid directly to the discharge region 29.
