Abstract: 507,753. Automatic control systems. GENERAL ELECTRIC CO., Ltd., DALE, S. H., and SCHIFF, W. Oct. 18, 1937, No. 28332. [Class 38 (iv)] [Also in Group XL] Electromotive Force.-An electrical bridge producing voltage changes at its output terminals B, Fig. 3, in accordance with voltage variations at its input terminals A, comprises two parallel circuits containing respectively (1) a series connection of a linear resistance 1 and a constant voltage impedance 2 and (2) a series connection of a linear resistance 3 and an impedance 4 taking a constant current or a current which falls with increase of voltage. The bridge may be used to control automatically the output voltage of electrical apparatus, such as a dynamo-electric machine or mercury-arc rectifier. Fig. 2 shows a bridge comprising a neon tube 2, as constant voltage impedance, and pentode 4 taking a constant current. The points B are connected to the cathode and grid of a gas filled triode excited from a transformer 13 so that decreasing output voltage of a machine connected to terminals S will increase the average current in a contactor coil 14 to cause the short circuiting of a resistance 15 in the field circuit of the machine. Fig. 3 shows the armatures of two mechanically coupled motors A<1>, A<2> oppositely fed from gas-filled relays 20, 21, the cathodes of which/ are connected to a potentiometer tapping and the respective grids to the points B of a bridge according to the invention. The motors are arranged to adjust a field rheostat of a machine the output of which is connected across the points A. The bridge may control the ignition angle of a mercury-arc rectifier. To obtain a fall in current in the resistance 3 with increase of voltage and hence amplified variation from the bridge a screen grid valve may be used with its anode potential lower than its screen potential.

Abstract: 261,396. Berkel, C. F. M. van. Nov. 12, 1925, [Convention date]. Cutting slices in succession.-In a slicing- machine, the clamp-bar is pivoted to a sleeve which is locked automatically in position on its upright guide by a device which is released, without affecting the sleeve, by moving the clamp bar to a predetermined angular position. As shown in Figs. 1 and 2, the bar 5 is universally jointed to an arm 14 projecting from a sleeve 7 slidable on the guide 4 and provided with a manipulating handle 13. The other end of the bar 5 is pivoted at 8 between two bridge pieces 6<1> integrally connecting sleeve portions 6, the upright 3 passing loosely through an aperture 5<11> in the bar 5. A locking-ring 9 rests on a pin 10 and is pressed downwardly by a spring 11. The inner circumferential face of the ring 9 is chisel-shaped to bite into the guide. The ring is provided with an adjustable set screw 12 which abuts against the bar, the upward movement of which raises one side of the ring and releases it. Fig. 2 shows a resilient connection between the arm 14 and the bar 5. The bar 5 is pivoted to a bar 15 which is revoluble within the end of the arm 14, the arm 14 and bar 15 being connected by a torsion spring 17. The relative motion of the bar 15 and an arm 14 is limited by a pin 16 on the bar working in a slot 18 in the arm. In order to raise the clamp bodily, the sleeve 7 is released and then raised by the handle 13. When the bar 5 assumes the required angular position the ring 9 is released, after which the clamp is raised, as a whole, by the handle 13.
