Patent GB-901517-A (GB)
Title: Improvements relating to on-load tap-changing apparatus
Inventor: CALVERLEY HENRY BOLTON
IPC: H01F29/04
Filed: 1958-03-26
Abstract: 901,517. Transformers. ENGLISH ELECTRIC CO. Ltd. March 17, 1959 [March 26, 1958], No. 9668/58. Class 38 (2). In an on-load tap-changing system the centretapped transitional auto-transformer 14 is provided with an extra winding 14b which may be short-circuited so that with one end only of the centre-tapped winding 14a connected to a tapping on the supply transformer a voltage substantially equal to the voltage of that tapping is obtained from the centre tap. When the winding 14a is connected across two adjacent tappings and is to be disconnected from the lowermost of these tappings, a circulating current which, at the preferred load current, is equal and opposite to the current supplied to the load from this lowermost tapping can be produced in winding 14a by connecting winding 14b across impedances R1 and R2 in series. By then cutting out R1 after T1 has been opened a voltage is obtained at the centre tap corresponding to the voltage of T2 less a quarter of the inter-tap voltage. Closing of C2 to shortcircuit winding 14b then brings the centre tap of the voltage of T2. A voltage equal to a quarter of the inter-tap voltage can then be added to the T2 voltage by closing C5, opening C1 and closing C2 so that winding 14b is fed from a main transformer winding 10c via R2. The next step is then to short circuit R2 and close T3 bringing the centre tap to a voltage half way between the voltages of T2 and T3. Winding 14b may be supplied from secondary winding 10b or from primary 10a or from another source. C2 may be omitted or more than two resistors may be used to obtain extra voltage steps.

A method of making a coloured relief map section comprises ruling a transparent foil and a plastics sheet with grid squares, deep drawing the sheet on a relief mould having a shape corresponding to the desired relief map section and colouring areas or lines on the relief sheet. The sheet is then reflattened. A non-ruled transparent foil is attached above the ruled foil and the coloured areas or lines are transferred from the flattened sheet on to the non-ruled foil, starting from co-incident predetermined datum points on the margins of the ruled foil and of the flattened sheet, by shifting the transparent foils over the sheet. Coloured stencils are made in accordance with the areas or lines on the non- ruled foil and the stencils and a printer are used to transfer the areas or lines on to a further plastics sheet which is afterwards deep drawn on the relief mould. A relief map comprising a number of map sections is constructed by moulding adjacent sections with overlapping areas and joining the sections, e.g. by heat sealing, along the overlapping areas. The back of the map is provided with loops arranged in rows and adhered or heat sealed thereto, through which loops laths are inserted so that the map is kept flat. The laths may be rolled up with the map.

Patent ID-21410-A (ID)
Inventor: WALLACE J KENNETH
IPC: B41J2/175
Filed: 1998-09-21
Abstract: An ink containment and dispensing device (10) for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch (14), which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet (20), which is normally closed to prevent the outward flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump (18) provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm (44) that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber. The flexible pouch is contained within a rigid, outer shell (12) having an opposed pair of shorter sides interspersed with an opposed pair of longer sides, and the shorter sides of the shell, in the region of the closed end of a cup-shaped shell, are configured for grasping and for identifying the location of the closed end of the shell. <IMAGE>

Title: Digital communication method
Inventor: FURUSHIMA HIROAKI
IPC: H04L25/49
Filed: 1990-01-09
Abstract: PURPOSE:To obtain secure synchronism by monitoring the level which is a specific time after a level change point. CONSTITUTION:Synchronization is performed with the level variation of a symbol (a) from H level to l level and it is decided whether the level is 0 or 1 at timing (b) which is a time t2 after said point of time. The time t2 is almost a half as long as code length T and the code decision time is a time t2+ or -alpha. Then when '0' level transmission is performed, the code continues at 0 level for a time longer than the time t2+alpha and when '1' level transmission is performed, the 0 level continues for a time shorter than the time t2-alpha. Consequently, the 1 or 0 level is determined at the point of time which is the specific time after the code change point, so the level at this time is monitored to perform secure detection.

Title: Paper kind detector and image forming device provided with the same
Inventor: MATSUO KAZUYOSHI
IPC: G01N21/47
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To accurately detect the kind of paper at the top, in a cassette where a plain paper and an OHP sheet are mixed by setting the arrangements of light emitting and receiving elements with respect to a paper sheet, within specific angles. SOLUTION: This paper kind detector provided with a reflective type sensor is constituted of the light emitting and receiving elements 1 and 2. Then, the arrangement angles of the light emitting and receiving elements 1 and 2 with the paper sheets are set 15 deg.-30 deg.. Even in one plain paper or plural plain papers laid one on top of another, almost the same reflectance is shown. On the other hand, when one OHP sheet exists on the plain paper or as the number of sheets laid one on top of another is larger, the reflectance is higher. In other words, the arrangement angles of the light emitting and receiving elements 1 and 2 are set 15 deg.-30 deg., so that in light projected from the light emitting element 1, the light passing through the OHP sheet becomes extremely little and most of incident light becomes regular reflected light.  Therefore, even if one OHP sheet exists on the plain paper, the upper sheet is hardly influenced by the lower sheet and the kind of paper at the top in the cassette can be discriminated.

Filed: 1989-01-09
Abstract: PURPOSE:To prevent firing into a tank, even when combustion is continued on a screen, by allowing inactive gas to be automatically sucked when circulating gas is stopped between a plurality of screens provided in a ventilating passage. CONSTITUTION:Two or more screens 3 of narrow clearance are provided in ventilating passages 1a, 1b. A distance between the plurality of screens 3 is set in a manner wherein a device automatically replaces circulating gas with inactive gas obtaining a condition out of the limit of gas explosion even when the circulating gas in combustion is stopped. That is, because adjusting space, automatically performing outflow and suction motion of gas, is provided between the screens in the ventilating passage, a fire is prevented from infiltrating into the adjusting space 6 even when the upper part screen performs combustion of gas. Accordingly, no firing reaches even inside a tank because the adjusting space 6 arranges the screen out of the firing temperature of gas on a temperature gradient.
