Title: Improvements in or relating to resistance thermometers
IPC: G01K7/20
Filed: 1945-04-24
Abstract: 614,628. Electric thermometers. FOSTER INSTRUMENT CO., Ltd., and HACKETT, C. E. April 24, 1945, No. 10275. [Class 40 (i)] [Also in Group XXXVI] A resistance thermometer comprises a composite resistance made up of at least two component resistances of different materials such that the resistance-temperature curve is 'of predetermined form. For example, two wires such as platinum and nickel may be joined in series in the correct proportion on a common insulating former to produce a composite wire having a straight line characteristic. Two such thermometers can be used, e.g. in a Wheatstone bridge to give an accurate measure of the temperature difference regardless of the actual temperature. In the arrangement, Fig. 2, a Wheatstone bridge is balanced and a galvanometer 11 scaled 0‹ to 15‹ C. is at zero corresponding to thermometer 9 at 0‹ C. in series with external fixed resistance 13a which together form one arm of the bridge. Under these circuit conditions any increase in resistance of the thermometer 9 corresponding to its increase in temperature over the range 0‹ to 15‹ C. is directly measurable on the galvanometer 11. The measuring range may be increased to 25‹ C. by adding 10 to the scale reading and substituting a resistance 13b for 13a. Similarly, resistance 13c substituted for 13b adds 20 to the scale and so on to the lowest value resistance 13m, and finally with no external resistance at all in the circuit as at switch position 14n.

A heteroyarn is produced from at least two compatible polymeric components by forming at least one interface between the components in the liquid state, metering the liquid components together to a spinning jet having a plurality of orifices, extruding the liquid components through the orifices to form at least three visibly different kinds of filament, and thereafter collecting the filaments. Each polymeric component preferably is in an amount of at least 10% by weight. For simplicity of control it is preferred that there are two components only. The components advantageously are of the same basic material but have different colours and/or contain different amounts of delustrant. The interface or interfaces between the components may be formed either before the components pass through a metering pump feeding the spinning jet or within a metering pump feeding the spinning jet. The filaments may be formed from the components by melt-, wet- or dry-spinning as appropriate. The components may be synthetic material, for example polyamides, polyesters, polyacrylonitrile or copolymers of polyacrylonitrile, or of natural (i.e. cellulosic) origin, for example regenerated cellulose or esters of cellulose. Heteroyarns are produced in Example 1 by wetspinning two samples of viscose, the samples containing different pigments; in Example 2 by dry-spinning two samples of cellulose acetate dissolved in acetone, the samples having different colours; and in Example 3 by meltspinning two samples of nylon 6, one sample having titanium dioxide disposed therein as delustrant.

Title: Improvements in air or gas blast electric switches
IPC: H01H33/83
Filed: 1942-07-30
Abstract: 561,178. Gas-blast switches. FLURSCHEIM, C. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 30, 1942, No. 10683. [Class 38 (v)] Gas-blast switches employing a blast - guiding nozzle, which may be of insulating material or constitute a contact, and a resistance arranged in series with auxiliary electrodes in a circuit in shunt to main contacts and independent of the circuit through the latter, have means responsive to the current flowing through the resistance for causing a blast to flow past the gap between the auxiliary electrodes and interrupt the resistance - current. The invention is applicable to some of the arrangements of Specification 561,078, for example, to Fig. 5, as shown. The resistance 48 is preferably non-inductive and in series with auxiliary electrodes 21, 23 across the main contacts 1, 2, the latter being operated by the blast gas acting on a piston 7, which, at a certain point in the opening operation, uncovers port 18 to pass the gas as a blast to the electrodes in the auxiliary chamber 19. A valve 15 subject to the pressure on both sides of the nozzle 6 is also provided for operation as in the above Specification. The pipe 13 is extended at 39 to a spring-controlled valve 35 which normally closes a cylinder 29, apertured at 29a, but is movable by the plunger 33 of a solenoid 32 connected in the resistance-circuit between electrode 21 and cylinder 8. When the switch is breaking large currents, the valve 35 is opened to admit the blast at once, without the delay incurred with light currents, and the pressure is admitted also behind a piston 40 which holds valve 35 open, even though the solenoid-current falls, until the main control valve closes. Electrode 23 may normally engage 21 and be movable by the pressure in chamber 19. Specification 541,949 also is referred to.
