Title: Controlling electromagnetic valve of a fuel pump
Inventor: SIEBERT HANS-JOACHIM
IPC: F02D45/00
Filed: 1991-02-01
Abstract: Controlling actuation of an electromagnetic valve of a fuel pump comprises determining, by way of electronic control equipment (30, Fig 1), a desired fuel conveying start (FBS) and a desired fuel conveying duration (FDS) in dependence on engine operating parameter values (speed, air or fuel temperature, lambda, acceleration pedal position etc). From these, control (30) calculates a drive-open instant E and a drive-shut instant A for the valve taking into consideration the switching times TA, TE of the valve. The actual switch-open time TEI and actual switch-shut time TAI of the valve, calculated from the actual fuel conveying start FBI and actual fuel conveying end FEI respectively, are used to update subsequently used values of the switching times TA, TE. These may be checked against allowable ranges to detect malfunctions. <IMAGE>

Title: Flap valve for overflow pipes.
Inventor: JONES RICHARD
IPC: F16L55/10
Filed: 1991-06-12
Abstract: Overflow pipes are uncovered and unprotected. They are liable to invasion by spiders, wasps, ants and other insects throughout the year, and during the winter when there is severe cold wind that can travel along the pipe causing possible freezing of the water system and cold coming into the home. The invention can help stop these problems by covering the end of the pipe but allowing water to flow out when necessary. The invention comprises of a flap that is free moving but attached to a clip that fits round the end of the pipe. The flap drops down to cover the end of the pipe, so keeping out any insects or freezing wind. If there should be an overflow the pressure of the water will lift the flap enabling the water to be released. <IMAGE>

Patent GB-2253037-A (GB)
Title: Air conditioning apparatus
Inventor: ICHIKAWA YASUNORI
IPC: F25B13/00
Filed: 1992-01-28
Abstract: In a heat operation mode, refrigerant discharged from a compressor (1) flows via air heat exchangers (24, 34, 44), an expansion valve (12), and a water heat exchanger unit (3), back to the compressor (1). The expansion valve (12) has a heat-sensitive sensor (12a) for sensing a temperature of the refrigerant taken in by the compressor (1). The opening degree of the expansion valve (12) is changed in accordance with a difference between the temperature of the refrigerant flowing therein and a temperature sensed by the heat-sensitive sensor (12a). A bypass (17) is provided for supplying part of the refrigerant passing through the air heat exchangers (24, 34, 44) to the suction side of the compressor (1). The bypass (17) is caused to open when the temperature of water supplied to the water heat exchanger unit (3) increases. The low-temperature refrigerant then flows to the suction side of the compressor (1) to cool the heat-sensitive sensor (12a) of the expansion valve (12). An unnecessary increase in opening degree of the expansion valve (12) is prevented. <IMAGE>

The lid is pivoted mid-way between its ends on a U shaped member (19) having arms (21) which can support the lid in a raised position. Spring struts (32) keep the lid in the raised position and, by virtue of a pivot pin (31) offset from the lid pivot pin (24), provide an overcentre action when the lid is rotated through approximately 180 degrees, to bring the other surface (17) uppermost. In a first modification (Fig 6, not shown) the pivots of the U shaped member and the struts are arranged to bias the lid in the downward direction when it is lowered with its one (normally upper) surface uppermost. In a second modification (Fig 7, not shown) the spring struts pivot about the same pivot axis as the lid and there is no overcentre action. <IMAGE>

Title: Using data from a borehole televiewer in an active well to determine fluid properties
Inventor: ANGEHRN JORG A
IPC: E21B47/10
Filed: 1992-05-27
Abstract: The method involves determining the wall effects from the data, and factoring out the wall effects from the data to determine the fluid properties. Wall effects may be determined by determining the maximum echo amplitude values recorded for each beam position of a circumferential scan of the wall. Fluid properties can be determined from the amplitude data by calculating the ratio of average to maximum amplitude values recorded for each beam position of a circumferential scan of the wall. Fluid properties may also be determined by determining the elapsed time between similar scan images on each scanner of a televiewer with multiple scanner sections, or by introducing into the borehole a known discontinuous material at a known distance from the televiewer and determining the elapsed time between injection and detection of the material by the televiewer, or by using pattern recognition technology to locate and analyse bubbles from amplitude data from a stationary televiewer.
