Filed: 1942-03-06
Abstract: 556,607. Inductance measurements. KAPELLA, Ltd., and REASON, R. E. March 6, 1942, No. 2963. [Class 37] [Also in Group XXXVIII] A measuring apparatus comprises two variable inductances so controlled in accordance with the quantity to be measured that a change in such quantity causes one inductance to increase and the other to decrease, an A.C. source, and a metering circuit including a D.C. meter and two rectifiers which are respectively in circuit with the two variable inductances and through which the meter is differentially energized, each inductance and the associated part of the metering circuit being energized in parallel from the A.C. source through an impedance, characterized in that the impedance of each variable inductance bears to the associated impedance of the metering circuit a ratio not greater than unity or not less than 1: 3. As shown in Fig. 1 a detector member which moves in accordance with the quantity to be measured is directly connected to an armature A common to two detector coils B1, B2 and arranged so that movement from its balanced position increases the inductance of one coil and decreases that of the other, the inductances being equal in the balanced position. The coils B1, B2 are connected in series with impedances C1, C2 across similar secondary windings D1, D2 of a transformer whose primary D is fed from an A.C. source E. Full-wave rectifiers F1, F2 are connected in parallel with the coils B1, B2 and have loading impedances G1, G2 connected across their output terminals. One of the output terminals of one rectifier F1 is directly connected to the output terminal of like polarity on the other rectifier F2 and a D.C. meter H is connected between the other two rectifier terminals. To prevent inaccuracies in the meter reading due to variations in the rectifier impedances, the impedance of each detector coil B1, B2 has a value between that of the rectifier circuit across it and one-third thereof, the ratio preferably being about one-half. In a modification the output terminals of one rectifier are respectively connected to the output terminals of opposite polarity of the other rectifier, the meter being connected between these connections. The loading impedances G1, G2 are omitted, the meter itself serving as a load for the rectifiers. In another arrangement, Fig. 3, the A.C. source L is connected to the input terminals of the bridge formed by the two detector coils M1, M2 and the two series impedances N1, N2, half-wave rectifiers O1, O2 in series with loading impedances PI, P2 being connected across the detector coils M1, M2. The meter Q is connected between the junctions of the rectifiers and their loading impedances. The two detector coils M1, M2 are controlled by a single armature as shown in Fig. 1 and the ratio of the impedance of each detector coil to that of the metering circuit across it lies between unity and one-third and is preferably about one-half. Specification 541,628, [Group XXXVIII], is referred to.

[Classes 36 and 38 (i)] A terminal for attachment to sheet material such as the containers for resistors, or condensors, comprises a hard cylindrical insulating bush 4, of elliptical, spiral, or other non- circular cross-section and halving a longitudinal hole 6, countersunk at one end 7, to accommodate a conductor 11. A washer 9 having an aperture similar to the cross-section of the bush, is assembled over it and locked by an anticlockwise rotation of the washer relative to the bush. The container 1 has a corresponding opening through which the assembly of washer and bush is inserted from inside, and locked in position by a clockwise rotation. The bush may be metallised over the area 8, Fig. 5, and around the countersink 7, and solder applied to these metallised zones to effect a hermetic seal with the container and conductor 11. A terminal tag 12 having a central hole of crosssection similar to the bush, may be locked thereon by anti-clockwise rotation. In Fig. 9, a metal bush 14 of similar non-circular crosssection, having an axial hole of somewhat larger diameter than the wire 18, has the end 15 reduced to form thin walled tubes. The wire is first threaded through a thin tube 17 to which it is secured by flattening the end of the tube at 19, a hole 20 being provided for fixing external wiring. The tube 17 is united to the bush 14 by a glass seal 16. Hermetic sealing may be effected by soldering the joint between the bush and container. In Fig. 7, (not shown), the wire itself is sealed through the bush with a metal-to-glass seal as 16. Metal bushes in insulating strips are also referred to.

Title: Improvements in air-oxygen mixing apparatus for respiratory air locks

Abstract: 724,929. Injectors. UNION CARBIDE & CARBON CORPORATION. Feb. 6, 1953 [Feb. 9, 1952], No. 3344/53. Class 71. [Also in Group VI] In a device for mixing two gases, a high pressure oxygen is supplied through the'nozzle of an injector and the area of the throat, through which a lower pressure gas is drawn, is variable in response to the pressure of the first mentioned gas. The apparatus described concerns the mixing of air and oxygen for respiratory equipment. Oxyger is supplied through a stop valve 15 to the centre bore 16 of an injector nozzle 17. Air is thereby drawn in through a port 21 and through a throat 18 in a tubular member 26, whence the mixture is passed to the patient. The nozzle 17 is formed in one piece with a piston 23 and oxygen pressure, acting through a duct 22, bears on the upper side thereof in opposition to a coil spring 25. Consequently, with increased oxygen pressure, and thus rate of flow, the nozzle is moved' downwards against the spring 25, thereby reducing the effective throat area and the proportion of air entrained. The parts are so dimensioned that the total flow of mixture remains constant, only the proportions changing. The total volume supplied to the patient may be adjusted by altering the axial position of the throat member 26. In modified forms, see Figs. 7 and 8 (not shown) the throat member is also made movable under the influence of the applied oxygen pressure, by being mounted on a piston, the movement of which is controlled by the oxygen pressure in opposition to a spring. By using springs of different strengths the relative movement of nozzle and throat may be varied and the proportion of constituents in the resultant gas mixture consequently changes in a non-linear manner with respect to the oxygen pressure.

Abstract: 575,053. Rotary furnaces. SMIDTH & CO., Ltd., F. L. Feb. 23, 1944, No. 3409. Convention date, Feb. 8, 1943. [Class 51 (ii)] [Also in Group II] A method of converting finely divided ironbearing materials into the form of nodules suitable for treatment in furnaces in which an agglomerating-agent in the form of a mixture of ferric oxide and lime in such proportions that the mixture will pass directly from the solid to the liquid state on heating is caused, while molten, to coat the iron bearing materials and so agglomerate them into nodules. The agglomerating-agent may contain from 15-32 per cent. of lime. Preferably the amount of the agent used is from 10-25 per cent. of the weight of the iron bearing materials. In one method of carrying out the invention, a mixture of materials which will provide ferric oxide and lime is added to the iron-bearing materials and the resulting mixture is agitated and heated. This operation may be performed in a rotary kiln from which the nodulised material is discharged. Alternatively the agglomerating-agent may be separately prepared and added in a molten state to the iron-bearing materials. In the apparatus shown, the mixture of lime and ferric oxidebearing materials is fed by a hopper 14 to a rotary kiln 10 heated by a burner 16 projecting into a hood 15. In the kiln the material is calcined and melted and collects in molten form in the bottom of the hood 15. Iron-bearing materials are fed by a screw conveyor 27 to the rotary nodulising drum 22. This drum is heated by burner 23, into the blast from which the molten agglomerating-agent drops from a nozzle 20 and is sprayed over the iron-bearing materials. The mixture hardens rapidly in the form of nodules on leaving the hot zone. These fall into a hopper 21 and pass through a cooler 29 where they are cooled in an air blast, which provides pre-heated air for combustion at burners 23 and 16.
