Abstract: 1,110,517. Magnetic tests. LICENTIA PATENT - VERWALTUNGS G.m.b.H. March 22, 1967, No.13510/67. Heading G1N. In the measurement of the magnetic properties of a moving sheet metal strip, in which the strip is surrounded by exciting and pick-up coils 6, 6a, the strip is guided in a U-shaped loop round a roller 5 of magnetic material, and a further roller 4 of magnetic material, against whose periphery the strip is held by rollers 2, 3, which completes the magnetic circuit. The rollers 2, 3 may be constituted by a number of rubber tyred wheels to prevent slip between them and the strip. The roller 5 may be mounted on a spring bearing and serves to short circuit that part of the strip which is curved so that the effects of bending the strip on its magnetic properties are not detected by the coils 6a. The strip is fed through the coils 6, 6a at constant speed, tension dynamometers associated with rollers 7 and 8 controlling the speed of a winding drum 10 and feed rollers 9 respectively.

Abstract: 664,858. Control of A.C. motors. DECCA RECORD CO., Ltd., and O'BRIEN, W. J. Aug. 18, 1950. [May 20, 1949] No. 13598/49. Class 38 (iii). [Also in Groups XL (b) and XL (c)] - An A.C. motor arranged to drive the deflection-coil holder of a radar plan-position indicator in synchronism with the aerial rotation (see Group XL (c) ) may be fed from a D.C. supply such as is often provided on ships. In a first arrangement 9 and 10 are the stator coils of a two-phase motor and are connected in parallel, capacitor 11 being introduced to provide the necessary phase shift in the currents through the two coils. A potentiometer consisting of resistors 14 and 15 and the two fixed contacts of a single pole, two-way switch are connected across the D.C. source 13. The switch 18 is operated for example at 180 times per aerial revolution and thus feeds the coils 9 and 10 connected between its movable' arm and the junction of resistors 14 and 15 with a square wave A.C. supply. Capacitor 12 is to reduce spurting. In an alternative arrangement (Fig. 3) the steady current drain of the potentiometer is avoided by providing a condenser 12 in series with the coils 9 and 10 of such value that the circuit is resonant at the normal speed of operation of switch 16 thus causing an alternating current to flow through them.

Abstract: 239,911. Albanese, G. Sacco-. June 12, 1924. Flow meters, pressure-actuated. - In apparatus for measuring at a distance the rate of flow of a fluid, of the type comprising a resistance included in an indicating and recording circuit and adapted to be varied by mercury contained in a receptacle which is tilted in accordance with the flow, the resistance is arranged in sections connected to contacts which are arranged in the wall of the receptacle. As shown in Figs. 1 and 2 a U-tube having its upper ends connected has a number of contacts L in the leg 1 connected to a series of superposed resistance coils R. The insulating block D which carries the contacts has a groove A which together with the tube 2 contains mercury. A float 3 which moves in accordance with the fluid level above a weir or notch tilts the U-tube and causes the mercury to vary the resistance in the leg 1 and so give an indication on the ammeter E and a record on the ampere-hour meter F. In a modification the resistance coils R are located between the legs 1, 2 and are connected to contacts on a rod which is inserted concentrically in the leg 1. In this form the relation between the variation of current in the indicating circuit and the movement of the floa+, is determined by a system of cams interposed between cables connected to the float and the U-tubes.. In a modification, the U-tube device may be tilted by the vane which is immersed in the fluid transversely of the direction of flow. In another form a cylindrical box which contains mercury is rotatably mounted and has contacts disposed around the periphery and connected to resistance coils. The box may be operated by the float through the intermediary of a rack and pinion. The ends of the U-tube may be open to the atmosphere.
