Title: Automatic voltage regulators
Inventor: DARBY KENNETH
IPC: B03C3/68
Filed: 1955-05-12
Abstract: 832,342. Automatic control systems for electrostatic precipitators. LODGE-COTTRELL Ltd. June 1, 1956 [May 12, 1955], No. 13779/55. Class 38 (4). An electrostatic precipitator is operated with the average electrode voltage at its maximum possible value, and this is detected either by a voltage measuring device with a long timeconstant, or by a photo-electric smoke density detector-the smoke density being proportional to the average voltage. The precipitator, Fig. 2 (not shown), is supplied through a high resistance from a rectifier and a motor-controlled high-voltage transformer. A portion of the electrode voltage is tapped off a potential divider and applied to a self-balancing potentiometer which provides a measure of the electrode voltage. The potentiometer balancing servomotor also moves a contact SS through a slipping clutch so as to close the contact when the voltage is rising, and open it when the voltage is falling. With the contact SS closed, relay R1 is energized, and the voltage controlling motor M is energized to raise the voltage by a fixed increment whenever a timer (not shown) energizes relay R2. When the optimum electrode voltage is reached, a further increase in supply voltage will cause a drop in average electrode voltage, Fig. 1 (not shown), and hence contact SS will be opened to change over contact R1C2 and so energize relay R4 from the capacitor C to briefly energize the motor M in the " reduce voltage " sense over contact R4C2. In a modification, Fig. 4 (not shown), the voltage reduction is controlled by a further timer instead of the capacitor. In a further modification, Fig. 7 (not shown), the supply current is limited by a current responsive relay which when energized interrupts the " raise voltage " circuit and energizes the motor to reduce the voltage. It is stated that the output of a photo-electric smoke density meter may operate the system instead of using the voltage measuring potentiometer.

Abstract: 851,932. Variable-speed gear. BORGWARNER CORPORATION. May 6, 1957 [May 7, 1956], No. 14412/57. Class 80 (2). A variable-speed gear for a motor vehicle comprises an hydrodynamic torque converter having an impeller 21 connected to input 10, a two-stage turbine 27, 30 connected to a ring gear 49 of a simple planet train, and a reactor 34, the planets 50 of the train being carried by an output shaft 11, whilst its sun 48, for low ratio, can be held by a brake 16, which, through a oneway device 43, also holds the converter reactor 34 from reverse rotation. In low ratio the torque converter is thus wholly in series with the reducing planet train. A fluid-pressure applied disc clutch 14 directly connects input and output 10, 11 for mechanical direct drive (high ratio); and for reverse the turbine 27, 30 and ring gear 49 are held by a second brake 15, which causes the reactor 34 to drive the sun 48 backwards, the planet train, still in series, then passing reduced drive to output. Hydrodynamic braking of the vehicle is provided by applying the reverse brake 15 together with the direct-drive clutch 14. The trailing edges of the impeller blades 21 and leading edges of the turbine blades 30 may incline backwards or forwards. The direct-drive clutch 14 is engaged by fluid pressure supplied at 62 to a combined presserplate and piston 54, slidably keyed by bolts 20 to the input casing in which is welded a plate 56 supporting a back plate 53. Input and output driven pumps 69, 70 supply a servo system feeding the clutch and brakes. Specification 802,956 is referred to.

Title: Process for the manufacture of pulverulent catalysts for the synthesis of ammonia
IPC: B01J21/02
Filed: 1923-06-07
Abstract: Catalytic materials for use in the synthesis of ammonia are produced by heating an alkaline earth metal or lithium in the compact state in the presence of a gas, such as ammonia or hydrogen, with which it will combine to form a dissociable compound, mixing the compound with an inert oxide such as lime or magnesia, heating the mixture in vacuo, and finally allowing it to cool in an atmosphere of nitrogen. The product contains the nitride of the metal in a finely divided state.  The addition of the inert oxides prevents the powdered metals from fusing and agglomerating during the heating process.  According to the example, commercial lithium is heated in pure, dry ammonia, the resulting amide mixed with powdered lime or magnesia, heated in vacuo, and then cooled in a current of nitrogen.  If the alkaline earth metal or lithium be heated in hydrogen, the corresponding hydride is formed and may be treated in the same way as the lithium amide.  It is stated that the synthesis of ammonia can be effected at atmospheric pressure or low pressure by using the products as the catalytic materials.  The Specification as open to inspection under Sect. 91 (3) (a) describes the use as catalyst of the finely divided metal itself, which is obtained, in admixture with the inert oxide, by omitting the step of cooling in nitrogen.  This subject-matter does not appear in the Specification as accepted.ALSO:The nitrides of alkaline earth metals and lithium in a finelydivided state are prepared by heating the metal in the compact state in the presence of a gas, such as ammonia or hydrogen, with which it will combine to form a dissociable compound, mixing the product with an inert oxide such as lime or magnesia, heating the mixture in vacuo and finally allowing it to cool in an atmosphere of nitrogen.  The addition of the inert oxide prevents the powdered metals from fusing and agglomerating during the heating process.  The amides and hydrides of the above metals are formed during the initial heating in the presence of ammonia and hydrogen respectively.
