Title: Improvements in or relating to devices for measuring resistances
IPC: G01R27/02
Filed: 1952-04-15
Abstract: 711,189. Measuring bridges, resistance measurement. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. April 15, 1952, (April 11, 1951.] No. 9401/52. Class 37. [Also in Group XXXVIII] In an automatic resistance measuring device, a standard voltage is connected across a circuit comprising the unknown resistance through a moving coil galvanometer without restoring torque, whose deflection operates a known regulator to produce a variable current such as to produce a voltage drop across the unknown resistance sufficient to counterbalance the standard voltage, the regulator current being measured as an indication of the resistance value. Fig. 1 shows an unknown resistance 1 of magnitude R connected to a standard cell across terminals 2, 2<SP>1</SP> through a moving coil galvanometer 3 having no restoring torque which operates a variable element of an A.C. regulator 5 feeding a detector amplifier 6 whose unidirectional output current I flows through resistance i in series with an ammeter 7, to produce a voltage drop which approximately cancels the standard voltage U, U so that I = - and the ammeter may be graduated R to indicate resistance directly. Fig. 2 shows a modification in which the unknown resistance i is connected in one arm of a Wheatstone bridge A B C D having a voltmeter 11 across diagonal C D energized by the regulated unidirectional current I across diagonal A B, which is also connected through the galvanometer coil to the standard cell. Initially for a given value of resistance 1 the bridge is balanced and the voltmeter reads zero, and the voltage drop across A B balances out the standard voltage. Variation of the resistance 1 unbalances the bridge to produce an indication on voltmeter 11, a variation of the bridge current and a corresponding voltage drop across A B, which produces a deflection of the galvanometer and a correlated variation of the bridge current to produce balance between the standard voltage and the voltage across A B. The voltmeter 11 may be calibrated in percentage variations of the resistance i, or directly in degrees centigrade when the variable resistance is a thermometric element. The measuring instruments may operate recorders. The regulator device may be of the kind described in Specification 587,459 wherein one element of a condenser or mutual inductance is mechanically varied to control the coupling of the output of a high frequency generator to a detector-amplifier.

Inventor: AUSTIN HERBERT
IPC: F42C9/12
Filed: 1916-07-06
Abstract: 125,412. Austin, H. July 6. 1916. Projectile fuses.-Relates to time fuses in which the fuse composition is contained in a lead or like tube, and consists in providing a cutter which is operated by the explosion of the detonating cap so as to pierce the tube. and allow the flash to ignite the fuse. In the construction shown in Fig. 1, a cutter m, a cap d<1>, and a striker needle h' are mounted within a hollow lug D<1> which is integral with a dome B, rotatably mounted on a base A. The fuse-tube n is located within a groove in the base. A shear-pin q normally connects the part m to the wall of the dome. When the projectile is discharged, a striker H<1> sets back and causes the needle h' to ignite the cap d<1>. The force of the explosion drives the cutter m into the fuse tube n, shearing the wire q, and the flash passes to the fuse composition through a hole (not shown) in the cutter. Fig. 5 shows a modification in which the needle h<3> is integral with the cutter m, the cap d' being driven back against the needle by a headed pin p when the projectile is discharged. Specification 124,806 is referred to.

Title: Improvements in the anti-shrinking treatment of animal fibres
IPC: D06L4/23
Filed: 1943-06-15
Abstract: Fabrics or other textile materials consisting wholly or partly of wool or other animal fibre are treated with an aqueous solution of a permanganate and with either a dilute aqueous solution or suspension of a nitrogen-chloro compound or of an alkali metal or alkaline earth metal hypochlorite or hypobromite, in order to reduce their tendency to shrink.  The materials may be treated with the permanganate and hypochlorite or hypobromite, together or in either order.  The process is applicable to wool materials containing cellulosic fibres such as cotton or rayon.  The term nitrogen-chloro compound includes those compounds in which the chlorine atom is directly attached to the nitrogen atom. Specified compounds are nitrogen trichloride, monochloramine, p-toluene sulphonchloramide and sodium-o-dichlorobenzene sulphonchloramide.  Metallic salts such as magnesium sulphate, calcium chloride, calcium acetate, barium chloride, barium acetate and/or zinc sulphate may be added to the hypobromite or hypochlorite solution.  The pH values of the solutions are preferably adjusted to 5 to 6 for the permanganate solutions, 1 to 2 for the nitrogen-chloro compound solution and 8 to 10 for the hypohalide solution.  To the permanganate solution may be added salts such as magnesium sulphate, calcium chloride, barium chloride and zinc sulphate, alone or in admixture, and discolouration due to permanganate is removed from the materials by bisulphite or sulphurous acid.  In the examples: (1) wool is treated at 40 DEG  C. with an aqueous acidified solution of potassium permanganate.  The material is rinsed and treated in a solution of monochloramine. Finally, the wool is bleached with a solution of sodium bisulphite. (2) Botany yarn is treated with an acidified solution of potassium permanganate, rinsed, freed from acid by sodium sesquicarbonate and treated in a cold aqueous solution containing sodium hypochlorite and calcium chloride.  Antichlor treatment with acidified bisulphite is applied.  (3) Wool is treated in a bath containing potassium permanganate, sodium hypochlorite, calcium chloride, zinc sulphate and sulphonated fatty alcohol.  (5) Botany yarn is treated in a bath containing sodium hypochlorite, calcium chloride and sulphonated fatty alcohol.  A dilute solution of potassium permanganate is then added, with subsequent addition of acidified bisulphite solution to remove the discolouration.  (7) Botany yarn is treated with an acidified solution of permanganate, and then with an acidified solution of sodium-p-toluene sulphonchloramide.  Discolouration is removed by the addition of bisulphite.  The treatment of the invention facilitates subsequent dyeing operations.
