Patent GB-2163251-A (GB)
Title: Infrared gas detector
Inventor: THINGBO DAG
IPC: G01N21/35
Filed: 1985-07-17
Abstract: An infrared gas detector for methane uses a sensor head connected by optical fibres and measures transmission through the gas at a wavelength coinciding with an absorption line of the gas. A reference is established by making a number of measurements outside the absorption band in an IR spectrum analyser and calculating a reference level in the center of the absorption band. The ratio between calculated reference value and measured value in the absorption band is a measure of the gas concentration in the sensor head. The IR spectrum analyser is implemented by the aid of a pivotal optical interference filter, whose center wavelength will change with the angle of incidence of the incident collimated light beam. Thus, the filter is secured to a pivotal axis controlled by a servo motor or an optical scanner. The control signal is provided by a microcomputer. <IMAGE>

Title: Air/fuel ratio feedback control system effective even during engine warm-up
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/00
Filed: 1986-04-17
Abstract: The system for feedback control of the air/fuel ratio in an internal combustion engine uses an oxygen sensor (50) to detect the actual air/fuel ratio in the exhaust gas. The system also has an electronic control unit (100), which outputs a control signal (Si) to regulate, e.g., the amount of fuel injection, by producing a signal indicative of the deviation of the detected air/fuel ratio from a target value and performing proportional and/or integral treatment of the deviation signal. The control system further comprises means (40) e.g. an engine coolant temperature sensor to detect the degree of warm-up of the engine and means to variably determine the values of the proportional constant (Cp) and/or the integration constant (Ci) accordingly. The feedback control operation can be started soon after starting the engine even in the case of cold-starting. The oxygen sensor (50) is described in detail and comprises a sensor cell and a pump cell each comprising an ion conductive solid electrolyte. <IMAGE>

Patent GB-2242024-A (GB)
Title: Ultrasonic testing of gas cylinders
Inventor: PACIEJ RICHARD C
IPC: G01N29/04
Filed: 1991-03-11
Abstract: The present invention provides an apparatus and method for ultrasonically testing the internal neck-shoulder region of a large number of gas cylinders for radially oriented defects. The apparatus and method includes housing an ultrasonic transducer within a shoe in a predetermined orientation wherein the transducer is wedged at a wedge angle so that ultrasonic pulses travel directly through the shoulder region to the top and bottom of the internal neck-shoulder region and is also outwardly skewed within the shoe at a skew angle such that the radially oriented defects reflect the ultrasonic pulses and produce return echoes. An automated scanner moves the shoe and therefore, the transducer in a predetermined pattern such that the entire internal neck-shoulder region of the gas cylinder is scanned. The scanner is supported by a stand that allows the automated scanner to be rapidly set up on the gas cylinders being tested. A processor activates the transducer to produce ultrasonic pulses, controls the automated scanner and responds to the return echoes for indicating the presence of the radial defects that require the removal of a particular one of the gas cylinders from service.
