Title: Method and apparatus for orientating a flat article
IPC: G01D5/46
Filed: 1980-09-26
Abstract: A method of automatically orientating a flat article such as a ceramic plate with a shaped edge comprises positioning the article (1) on a rotatable table (7) and bringing up to the edge of the article (1) a plurality of sensors consisting of associated pairs each comprising a nozzle (9) and a pressure sensor (10). The nozzles (9) direct respective air jets towards their associated pressure sensors (10), which latter produce output signals when they detect a pressure rise due to impingement of the air jet. The air jets are directed across the edge of the article (1) at positions such as to be interrupted by the edge except when the article (1) is in the required orientation in which case the air jets pass across recesses in the edge to reach the associated sensors (10) which then produce an output signal to stop the rotation of the table. <IMAGE>
Patent GB-2064780-A (GB)
Title: Apparatus for measuring the efficiency of combustion appliances
IPC: F23N5/00
Filed: 1980-10-22
Abstract: This disclosure relates to apparatus of the kind suitable for taking spot measurements of the heat loss or stack loss and/or efficiency ( eta ) in flue gases (stack loss) and comprises respective sensors (5, 3) for producing output signals which vary with the temperature and the concentration of a constituent gas e.g. O2 of the flue gases and microprocessor-based computation means (10) arranged to derive measurement values of (and numerically equal to) the measured temperature and constituent gas concentration, from the two sensors and to apply these measurement values in the computation of a predetermined formula relating the stack loss or efficiency to the measured quantities. In accordance with the invention, the apparatus is arranged to automatically calibrate each sensor signal from a test measurement prior to deriving the measurement values. This may be achieved in the case of a sensor having a non-linear response, by performing a calculation of a formula defining the non-linear response of the sensor using a coefficient derived from the test measurement. The sensor output signal is thus automatically calibrated and "linearized" from a single test measurement. The predetermined stack loss or efficiency formula may be modified for different types of fuel, and temperature and O2 (or CO2) values used in the calculation as well as the result of the calculation may be presented on a visual display (24).

Title: Differential pressure measuring apparatus
IPC: G01F23/284
Filed: 1981-10-26
Abstract: A differential pressure transducer of the diaphragm displacement type uses optical techniques to measure diaphragm displacement. White light from a source (38) is conducted by optical fibres to the transducer (30) and interference is produced between light reflected at a thickened region (37) of the diaphragm (32) and a partially reflecting end face of the light conductor which is lapped flat and parallel to the diaphragm surface. The interfering reflected light is conducted back to a prism (44) where it is dispersed on to photoarrays (45, 46). The wavelengths of dark fringes in the spectrum are measured to determine the displacement of the diaphragm. Measurements can be made on both sides of the diaphragm and used to eliminate dependence on refractive index. Alternatively, the light may have a single frequency which is swept through a frequency bond. <IMAGE>

Title: Improvements in and relating to fire and explosion detection
Inventor: BALL DAVID NICHOLAS
IPC: G08B17/12
Filed: 1983-07-25
Abstract: A fire and explosion detection system for discriminating between radiation produced by a source of fire or explosion to be detected and radiation produced by a source of fire or explosion not to be detected, comprises two radiation detectors 10, 12 respectively responsive to the intensity of radiation in different wavelength bands to produce respective electrical outputs. Detector 12 responds to a narrow wavelength band including 4.4 microns (to detect hydrocarbon fires). The latter band is included by the band to which detector 10 responds which is relatively broad. A rate of rise unit 22 and a threshold unit 24 responsive to detector 12 produce signals of one type when the rate of rise of, and the value of, the intensity of the radiation received by that detector exceed predetermined values. A ratio unit 16 measures the ratio of the intensities of the radiation respectively received by detectors 10 and 12 and produces a signal of the opposite type when the ratio indicates that the source of radiation is a fire or explosion to which the system is not to respond. An AND gate 36 produces a fire or explosion indicating output only when the signals of the first type exist in the absence of the signal of the opposite type. <IMAGE>
