Title: Axial sliding bearing
Inventor: SEMYONOVYKH ALEKSANDR SERGEEVISH
IPC: F16C17/04
Filed: 2015-07-14
Granted: 2020-07-05
Abstract: The invention relates to plain thrust bearings, wherein one working surface of which is made of siliconized graphite (or other antifriction material with similar characteristics) and can be used in assemblies of electrical machines and hydraulic machines having thrust bearings of a large size (with a diameter up to 900 mm), preferably electric motors driving a main circulation pump assembly (MCPA) of reactor assemblies, for example, in nuclear power plants. The plain thrust bearing comprises interleaving bearing bands and slots on the side facing to a set of sector. The bearing disk is provided with mounting surfaces, wherein external and internal rings securing the sectors made of antifriction material through elastic elements are mounted on the mounting surfaces. The sectors are fixed to deter them from rotation relative the bearing ring by intermediate bars arranged between the sectors, wherein the bars are fixed by inserting their pins into the openings in the bearing disk. The sectors made of antifriction material are provided with steps for the external and internal rings, wherein upper parts of the sectors are provided with roundings and lower parts of the sectors are provided with slots for mutual axial fixation. A sector’s lead-in edge is shaped approximately as a parabolic curve. Cooling and lubricating is carried out through interleaving channels formed by the bars, the sectors, the external and the internal rings.

Granted: 1994-10-19
Abstract: A digital integrated circuit incorporates a plurality of multi-port flip-flop circuits which are interconnected by a plurality of gate circuits (3,4,8,9). A separate source of clock pulses is provided for each of the ports of the multi-port flip-flop circuits, and each clock pulse source is selectively effective to cause the multi-port flip-flop circuits to perform independent functions. During operation under one source of clock pulses, the flip-flops perform their ordinary function as D type flip-flops. During operation under another source of clock pulses, the flip-flops function as one or more shift registers in order to set the flip-flops to a predefined initial state in accordance with serial input data, and/or to provide serial output data in response to the state of the flip-flops following a preceding operation. When a further source of clock pulses is effective, a plurality of flip-flops may be connected to function as a random number generator or as a signature generator so as to perform repetitive operations such as cycling the address inputs of a ROM and providing output signals corresponding to the operation of the ROM.
