Title: A Torque Transmission Arrangement comprising an Electric Slip Coupling
IPC: H02P29/00
Filed: 1968-05-10
Abstract: 1,168,041. Controlling clutches. SIEMENS A.G. 10 May, 1968 [10 May, 1967], No. 22428/68. Heading F2L. The energization of an electric slip clutch is controlled to maintain a desired output, speed. As shown, a diesel engine 1 drives a ship's propeller 2 through an electric slip clutch 4 and a gear 38. A machine telegraph 17 supplies a desired speed signal to a comparator 15 which receives a signal dependent on the actual output speed of the clutch from a tachometer 19. The signal from the comparator 15 is supplied to an amplifier 16 having a feedback 18, and the amplifier signal Md, which is a function of the difference between the actual and desired speeds, is fed to a multiplying device 34. Input and output signals supplied by tachometers 29, 19 are applied to a comparator 31 and the resulting signal is supplied to a function generator 32 which yields an output signal #(n1 - n2) the variation in which with variation in the input signal is approximately proportional to the reciprocal of the variation in the torque transmitted by the clutch with changes in the slip at constant excitation. The output signal f(n1 - n2) is applied to the multiplying device 34 which gives a signal U37 corresponding to the product of the signals Md and #(n1 - n2). The signal U37 is applied to a function generator 35 which produces a signal Ie* which is such that the magnetic flux produced in the clutch is proportional to the square root of the signal U37. Signal Ie* is fed to a comparator 22 which also receives a signal corresponding to the actual energizing current, and the difference between these signals is supplied to a variablegain amplifier 23 with a feedback path 24 and thence to a power amplifier 25 which supplies the energizing current to the clutch. A modified control for a slip clutch between an electric motor and a boiler feed pump has the function generator 32 supplying a signal f(n1 - n2) the variation in which with variation in input signal is approximately proportional to the variation in the torque transmitted by the clutch and is applied to a dividing device which also receives a desired output speed signal and passes the resultant signal to the function generator 35, the remainder of the circuitry being unaltered.

Abstract: 239,373. Dale, W. D., Hopkinson, R. A., and Hopkinson & Co., Ltd., J. Sept. 23, 1924. Bell-operating mechanism, electric; hell clappers.-In an electric bell in which the operating mechanism is enclosed within a water and gas tight casing b, a one-part stem or rod f, g carries at one end the hammer e and at the other end the armature of the electromagnet, whilst the intermediate portion g serves as a trunnion for oscillating the parts. The bearing g<1> for the trunnion g is formed between a boss on the casing b and the detachable cap i, and is lubricated by a screwed grease cap l which forces grease into the bearing, the grease also making the bearing water and gas tight. The hole n in the casing is large enough to admit the armature, so that the hammer armature and stem can be assembled as one unit before fitment. A lipped saucer o on the outer portion f of the stem collects condensed moisture, which is thus prevented from entering the bearing g<1>.

Abstract: 492,415. Fluid - pressure brakes. HARDY MASCHINENFABRIK UND GIESSEREI AKT.-GES., GEB. Aug. 19, 1937, No. 22766. Convention date, Aug. 29, 1936. [Class 103 (i)] in a triple valve the ratio of the areas of the pistons on which the train pipe and brake cylinder pressure act is variable during braking. The piston on which brake cylinder pressure acts to return the valve to lap position is in two relatively movable parts 2, 2a. The larger part 2a is only active to control the valve by engaging flange 6 when a spring 8 yields. Thus the preliminary movements of the valve are readily susceptible to the changes of train pipe pressure above the piston 1, being unopposed except for the brake cylinder pressure acting on the small area of the piston 2. There is a constant pressure in the chamber K. In a modification the piston 1 is in two parts which move together until the spring between them yields and thereafter the smaller part only is active.
