Title: Improvements in automatic load control systems for parallel connected alternators
IPC: H02J3/46
Filed: 1957-07-19
Abstract: 865,357. Automatic control systems for alternators. SUNDSTRAND CORPORATION. July 19, 1957 [July 25, 1956], No. 22901/57. Class 38 (4). In a system for parallel operation of alternators driven from aircraft engines through constant-speed drive units, the drive units are further controlled in accordance with alternator frequency and loading. Each alternator, e.g. 10, is driven by an aircraft engine through a drive unit 11 which maintains the speed constant as disclosed in Specification 735,194 and is also responsive as disclosed in Specification 813,279 to the output of a magnetic amplifier 25 to adjust the speed both for fine-frequency control and for load sharing. Load sharing.-A current transformer 21 measures the load current in one phase, and with the corresponding transformers of the other alternators is connected in a series loop, Fig. 3 (not shown). There is a contactor 20 linked with each main circuit-breaker to short out the current transformer of an idle alternator. The voltage appearing across the current transformer 21 is the vector difference between the current in that coil and the vector average of the currents in all of the other coils, and this voltage is applied across a resistor 30 in a phase comparator 24 the output of which is the " in phase " component of the current signal. This output is differentiated at 36, 37 and applied to one control winding of the magnetic amplifier 25, and integrated at 38, 39, 40 and applied to a second control winding of the magnetic amplifier 25 to control the driver unit 11. Speed control.-A third control winding on the magnetic amplifier 25 is energized from a bridge circuit consisting of fixed arms 73, 74 and a potential divider 65. The slider of the potential divider 65 is adjusted by the output shaft of a differential gear, Fig. 7 (not shown), the inputs of which are driven by two synchronous motors, Fig. 6 (not shown). One motor is energized from the alternator 10 and the other is energized via a power amplifier from a standard frequency tuning fork. The amplifier 25 adjusts the drive unit 11 to correct the speed. Specification 865,358 also is referred to.

Title: Diaphragm valves
IPC: F16K7/12
Filed: 1957-07-22
Abstract: 820,679. Valves. GRINNELL CORPORATION. July 22, 1957 [July 26, 1956], No. 23087/57. Class 135. A diaphragm valve has a diaphragm actuating member 24 formed with a socket 26, means, e.g. the tube net 43 and screw stud 38, connecting member 24 and diaphragm 17 and having a first portion 44 in the socket overlying the rim 46 of an aperture 47 in the bottom of the socket, means 50 carried by and limiting rotation of the first portion about its longitudinal axis, the first portion being movable longitudinally with respect to the rotation limiting means. In order to attach a diaphragm to the compressor, the diaphragm is rotated so that its stud screws into the nut. The socket is elliptical in crosssection and the nut is prevented from rotating therein by having the diameter of its head 44 slightly less than the minor axis of the ellipse, the head being slotted at 48 and carrying a key 50 in the slot which is slightly less than the major axis of the ellipse, so that the key jams on the sides of the socket and prevents rotation of the nut. The key has end legs resting on the bottom of the socket so that a space is left between the bottom of the key and the bottom of the slot 48, whereby, when the compressor is lowered by the manually-actuated screw 22, the compressor together with the jammed key moves relative to the nut to compress the diaphragm on a weir, thus preventing the stud alone exerting pressure on the diaphragm. In a modification, the key rests directly on the bottom of the socket and the stud slot 48 extends within the aperture 47.

Abstract: 307,820. Thornton, A. A., (G. & D. Manufacturing Co. Proprietary, Ltd.). Aug. 17, 1928. [A Specification was laid open to inspection under Sect. 41 of the Acts, March 15, 1929]. Moulding confectionery and sweetmeats. - In machines for moulding confectionery into ropes, rods, or bars of the type in which a, series of tapered rollers are arranged to form a conical vessel, means are provided for kneading the material during its passage through the rollers. In the preferred form the rollers are arranged approximately vertical and rotate bodily round the mass of confectionery, thus feeding the formed rope from the lower narrower end. Preferably the rollers are mounted eccentrically to knead the material by alternately increasing and decreasing the size of the chamber. Thus the rollers 1, Fig. 1, are mounted eccentrically on, and supported by, shafts 6 connected to a toothed ring 12 running in ball bearings on the member 4 and driven through the pinion shaft 14. Pinions 2 on the rollers gear with a fixed ring to rotate the rollers during their bodily movement round the member 4. The arms 5 carrying the machine can be swung about the main shaft to stop the forward feed of the rope when any interruption occurs in the normal working of an auxiliary machine such as a wrapping machine. Thus, the operation of a solenoid can move the arm 30, Fig. 4, of a bell-crank horizontally into the path of a pin 31 on the driving-wheel, whereby the arm is raised in a vertical plane to withdraw the arm 36 from the supporting prop 38 and allow the members 5 to fall into the inclined " stop " position. Buffers take up the shock during this movement, and a circuit-breaker may be operated automatically. The inclination of the machine may be adjusted by the hand-operated screwed shaft 23. The rollers may be heated by passing through a heated zone during their rotation.
