Title: Improvements in or relating to radiation pyrometers
Inventor: LAND THOMAS
IPC: G01J5/60
Filed: 1953-03-21
Abstract: 744,914. Radiation pyrometers. LAND PYROMETERS, Ltd. March 15, 1954 [March 21, 1953], No. 7843/53. Class 40 (3). In a radiation pyrometer suitable for measuring the temperature of molten glass use is made of infra-red radiation to which the glass is opaque. A pair of detectors connected in opposition being so disposed that both receive radiation from the hot source but one of the receivers having in its path a screen opaque to radiation in the long wavelength part of the infra-red spectrum. Thus the difference in output of the two cells indicates the red intensity of the lower wavelengths only. As shown, radiation from the hot body 5 passes through a fluorite window 6 transmitting as shown in the dotted curve (Fig. 1) to a thermopile 9 with strips sufficiently widely spaced to allow radiation to pass between them to a second thermopile 11. Between the two thermopiles is situated a silica window 10 having a transmissivity as shown in curve 1 of Fig. 1. This 'thermocouple is shunted by a resistor 12 which enables the relative sensitivities of the thermocouples to be adjusted. A thermistor 15 in series with the thermocouples and mounted on plate 14 corrects for ambient temperature while a further thermocouple comprising copper leads 17 and a suitable wire 17A joined at an insulating screw 17B attached to plate 7 corrects for heating of the plate. The assembly on which the thermocouples are mounted is adjustable over studs 20 against the action of springs 22 by nuts 21. In a modification (Fig. 5, not shown) an arrangement described in Specification 681,835 is used in which the end of the instrument near the hot body is provided by a polished concavity in which is a central fluorite window. This cavity when placed near the heated body produces black body conditions. In Fig. 6 (not shown) the housing is spaced from the hot body a fluorite lens being provided to direct the heat on to the thermopile. In Fig. 7 (not shown) the two thermocouples are situated side by side with a single fluorite window directing radiation on to both while in Fig. 8 (not shown) the thermocouples are each situated in a separate housing provided with a fluorite focusing lens. Photocells or polometers may be used instead of thermocouples.

Abstract: 348,277. Current, pressure, power, and frequency measurements. ARONWERKE ELEKTRIZITATS AKT.-GES., 39, Wilmersdorferstrasse, Charlottenburg, Berlin. March 11, 1930, No. 7851. Convention date, March 11, 1929. [Class 37.] Electrical values, such as power, pressure, or frequency are measured at a distant point by causing the primary measuring instrument to send to the distant point a series of directcurrent impulses, which are passed through the primary winding of a transformer, current from the secondary winding of which is rectified and passed through a ballistic galvanometer. As shown, the primary measuring instrument a,carries an interrupter b which opens and closes the circuit of a battery c at a rate proportional to the quantity to be measured. In this circuit is the pressure-winding d of a transformer and the winding e of a relay, the armature s of which connects one terminal of a ballistic instrument g to one end or the other of the secondary winding of the transformer, according as the primary circuit is open or closed. The other terminal of the instrument g is connected to the centre point f of the secondary winding. By this means the secondary current is rectified in the circuit of the ballistic instrument g. The magnetic circuit of the transformer may be saturated in order to render the flux independent of the strength of the current impulses. The relay winding e may be connected in parallel with the primary winding d instead of in series, as shown. Intermediate relays may be inserted in the direct-current circuit, a separate battery being used for exciting the primary winding d. A number of primary measuring instruments may be arranged so that each sends impulses to its own transformer, the secondary winding being connected to one ballistic instrument so as to indicate the sum or difference of the quantities measured.
