Abstract: 538,773. Rotary shaft bearing. AKER, E. S. March 5, 1940, No. 4122. [Class 12 (i)] A bearing suited for use with water-submerged shafts such as boat propeller shafts comprises a non-rotatable bushing element 14, Figs. 2 and 3, driven into bearing block.13 and formed with internal and external open-ended circumferential grooves 16, 18 connected by openings 19, and a journal sleeve 21 of hard or soft vulcanized rubber secured at its ends to the shaft 11 by clamp rings 22. The rings 22 may be formed with flanges 25 abutting the bushing element 14 and provided with notches 26 opposite the grooves in the body to allow the passage of water. The journal sleeve may be provided with pockets or channels 27 to increase the water flow over the bearing surface.

Title: Over-current relay
Inventor: SCHNABEL HANS
IPC: H02H3/08
Filed: 1968-01-26
Abstract: 1,218,074. Protective systems. STARKSTROM-ANLAGENBAU ERFURT VEB. 26 Jan., 1968, No. 4139/68. Heading H2K.  An electronic directional overcurrent relay arrangement comprises an AND gate 8 receiving one input from a current transformer 1 with load resistor 9 through an adjustable phase shifter 10 and a level detector 12. The other input to the AND gate is derived through a diode limiter 6 and a level detector 7 from opposing secondary windings of voltage transformers 2, 3, one of the voltage transformer primary windings being connected in series with Zener diodes 4, 5 across the other primary winding. The AND gate 8 provides an output when the current and voltage signals have predetermined magnitudes and have a predetermined phase relationship. A " compensation " device 13 is connected between the phase shifter 10 and the level detector 7, the device 13 reducing the response threshold of the detector 7 when high overcurrent conditions occur. The output from the AND gate 8 is applied to a pulse shaper 14 and from the shaper to a monostable multivibrator 16 and an inverter 19. When an OR-gate 18 receives no signal from either the multivibrator 16 or the inverter 19, an inverter 20 provides an output signal, e.g. for tripping a circuit-breaker.

Title: Arrangement for operating moving contact current converters
IPC: H02M1/26
Filed: 1954-02-19
Abstract: 760,730. Rectifying. AKT.-GES. BROWN, BOVERI & CIE. Feb. 19, 1954 [Feb. 19, 1953], No. 4920/54. Class 38 (2). In a contact rectifier with main contacts K<SP>1</SP>-K<SP>6</SP> and switching chokes 3a-3f of which the D.C. output is regulated by varying the contact closing stage length, the instant at which the contacts close is varied about the zero passage of the contact volts by altering the phase position of the synchronous motor 5 driving the contacts in such a manner that the duration of the closed contact period remains constant and the contacts open at a constant time after the beginning or before the end of the opening stage. The phase position of the motor 5 is varied by a regulator 6 in the supply to its rotor, which regulator is controlled by arrangement 28 in conjunction with contact LK which opens and closes in synchronism with contact K<SP>2</SP>. At the beginning of the opening current step at contact K2, the changing flux in its associated switching choke 3b develops a voltage in winding 23b which is applied to the grid of valve 8 as a firing pulse. Current flows in valve 8 and regulator 6 while contact LK is closed, i.e. during the opening step of contact K<SP>2</SP> until this contact opens, of an amount determined by the P.D. across resistor 24 and limiting resistor 8a. While contact LK and contact K<SP>2</SP> are open, current flows in the opposite direction through regulator 6 from a to b, through resistor 26. The regulator comes to a state of rest to give a fixed point of contact opening in the step, when the mean value of the opposite currents is equal. The instant of current opening can be set by varying resistor 26. The output is regulated by variation of premagnetization current supplied to windings 21a-21f which alters the time after contact closure at which commutation begins. The strength of the premagnetization current is varied to control the closing but not the opening step by varying the D.C. premagnetization of chokes 10a-10f in the supply from the A.C. mains R.S.T. to the windings 21a-21f. This D.C. premagnetization from supply 15 is varied automatically by controller 12 operated from across a resistor 18 carrying the main D.C. load. The regulator 6 may incorporate valves. Specifications 570,526 and 654,624 are referred to.
