Patent GB-2244559-A (GB)
Title: Reducing errors in liquid level measurement
Inventor: WOOD GRAEME G
IPC: G01F23/14
Filed: 1990-05-23
Abstract: Reduction of pressure measurement errors in determining liquid level in a tank (V) using differential pressure sensors (p-1, p-2, p-3) for measuring internal tank pressures is effected by having their external reference pressures dependent entirely on pressure in ducting (D) leading to a common reference (R). This eliminates the effects of local variations in ambient pressure due to e.g. wind effects. If the tank has a closed roof and the sensor (p-3) fixed above the liquid the reference preferably is outside the tank below the lowest sensor (p-3 or pw-2). If the tank has no pressure sensor (p-3) above the liquid, the reference (R) preferably is positioned to a float on the liquid surface or fixed near the top of the tank. For a floating roof tank the reference (R) preferably is on the floating roof. Readings of pressure and temperature (t) are taken to a computation unit (C). In an alternative the ducting (D) is sealed and contains a fluid. <IMAGE>

Title: Water tanks
Inventor: DEWEY NORMAN FRANK
IPC: E03B11/02
Filed: 1990-07-25
Abstract: A water tank (2) has an upper region (8) of an end wall (4) which extends upwardly higher than the opposite end wall (6). This enables that region (8) to have a ball-cock valve mounted therein, in e.g. a hole (26) in that upper region (8) so that the tank (2) may be filled substantially to the top of the opposite end wall, but the ball-cock valve may operate correctly. The tank (2) may have a lid with an inspection hatch therein. In a further development, the lid may form part of a housing enclosing the tank, with the tank being sealed to the lid and the lid being sealed to side walls of the housing. This enables the interior of the housing outside the tank to be sealed from the interior of the tank so that the interior of the housing outside the tank may contain pipework associated with the tank. The tank may be formed by panels or be an integral unit.

Patent GB-2253174-A (GB)
Title: Seal
Inventor: MASKELL WILLIAM CHARLES
IPC: C04B37/02
Filed: 1991-02-28
Abstract: A ceramic (or other solid) or metal seal is effected in a process in which the surface of a flat solid is prepared by rotating the solid about an axis perpendicular to its surface and to a flat grinding surface while pressing the solid and grinding surfaces together. This produces a pattern of concentric scratches 5 on the surface of the solid 1. A smooth metal, for example gold, is pressed against the prepared surface and held at an elevated temperature for an appropriate time. The pressure is then released and an hermetic seal has been formed between the solid and the metal which is stable over a range of temperatures. The process can also be applied with appropriate modifications to non flat surfaces where co-axial rather than concentric scratches are produced. A particular application of the process is the assembly of gas sensors incorporating one or more zirconia-gold seals. <IMAGE>

IPC: G11C7/06
Filed: 1991-12-31
Abstract: A circuit 50 controlling the voltage applied to a sense amplifier 70 and a memory cell 100 by setting the voltage at a given level (in this case, 4V) receives the voltage applied to the sense amplifier 70 and the memory cell 100 and generates an output voltage to the gate of the sense amplifier driver 61. It includes a comparator 50A which indicates if the voltage applied to the sense amplifier 70 and memory cell 100 is varied, a level shift circuit 50B for converting an internal power voltage into an external power voltage, a trigger circuit 50D, a driver control circuit 50F and a bias circuit 50E for maintaining constant the current flowing into the driving element of the driver control circuit 50F. Therefore, the voltage applied to the sense amplifier 70 and memory cell 100 will increase appropriately until it reaches a given level, when it will be maintained constant. Consequently, incorrect operation due to power noise is reduced, thus to improve the reliability of the semiconductor memory device. <IMAGE>

Title: A lexical analyzer for scanning multibyte character sets
Inventor: CALDWELL JEFFREY B
IPC: G06F9/44
Filed: 1993-01-15
Abstract: In order to scan multibyte character sets a lexical analyzer is built which factors regular expressions that contain multibyte characters, so that a single byte finite state automata can be constructed. A source program written in a programming language that is represented by both single byte values and two byte values can then be tokenized. Generating means for building the lexical analyzer is configured to accept an input specification which typically includes a regular expression(s) and a corresponding associated action(s). Factoring means factorizes the regular expression(s), if the regular expression(s) contains at least one two byte character, into a regular expression(s) containing only single byte characters. This will result in both a significantly smaller lexical analyser which uses substantially less memory and a lexical analyzer which easily recognizes a heterogeneous input stream of single and two byte characters.
