Title: Pole changing three=phase two layer winding for electromotor - has two sets of terminals and unsymmetrical winding group distribution to improve utilisation factors at low and high speeds
Inventor: BELIKOVA GEB NAUMENKO LJUDMILA
IPC: H02K17/14
Filed: 1978-11-16
Abstract: The winding is specif. applicable to a two-speed three-phase pole changing two layer winding with a pole pair ratio of 8:6 and employing 72 slots. The winding pitch is made to cover nine slot pitches, and the coils are distributed in 22 groups between the three phases. The winding has six terminals. The winding is thus distributed between the phases in unsymmetrical groups, but has the same number of coils per phase. The sequence of coils and coil groups follow a specified particular pattern. The arrangement gives a more favourable coil arrangement in the high speed connection and a winding factor some seven per cent higher than earlier designs with 24 coil groups and a winding pitch of 12 slots.

Title: Mine working area striding supports remote control - involves dual pressure valves conveying reversal impulse when two pressures are equal
Inventor: WINKLER JOHANNES
IPC: E21D23/14
Filed: 1979-05-30
Abstract: Operative functions, such as setting, exploiting or advancing, are set in motion by control impulses. The system is used in connection with hydraulic main control valves for individual units, in a remote control system for support units in underground mine working areas. Twin pressure valves are incorporated into impulse leads leading to the main control valves. These convey the impulse to reverse the main control valve only when the same pressure is in force at both control inputs of the twin pressure valve. The twin pressure valves have control connections which may be interchangeable. For striding support systems, this makes it feasible for a number of units to be controlled from a single position.

Title: Crowned tooth gear wheel production - uses ground master wheel with radial and axial crowning as drop forge die
IPC: B21K1/30
Filed: 1979-11-29
Abstract: The method produces crowned tooth gear wheels, with the extent and shape of contact reflections determined in advance. The gear wheel (6) has teeth (5) with the flanks (7) crowned to an optional curve longitudinally. The shape of the crowning depends on the required contact image (8), but usually it has a shape of an ellipsis with a horizontal major axis. The gear wheel is produced by a master wheel on which the required shape of crowning are obtained by grinding. The master wheel thus produced is used as a drop forging die for the production of the actual gear wheels.

Title: Cyclone dust separator which discharges to spray washing stage - then one or two filter stages before returning air for use
Inventor: GLAESER HANS
IPC: B01D46/24
Filed: 1980-05-12
Abstract: Separator for separating coarse, fine and extremely fine dust particles from air has a dirty air inlet pipe entering the conical cyclone vessel, tangentially, a bottom discharge for the coarser particles, and a central, coaxial riser pipe for the air leaving the cyclone; the air is extracted here by a coaxial fan rotor and receives an injection of water from a feed pipe coming from a settling tank. This water is broken up into fine droplets and centrifuged by the rotor onto the inner wall face of a cylindrical vessel, having a closed top, which coaxially surrounds the cyclone; the air flows down through this cylindrical vessel, leaves at the bottom and passes up into a filter space surrounding the cylindrical vessel and contained within a perforated wall. The air leaves this filter space through this perforated wall and pref. passes to a second filter space coaxially surrounding the first and containing finer filtering material, this in turn being contained within a second perforated cylindrical wall. Both these filter spaces are closed at the top. The fan rotor comprises a horizontal plate with blades below it for centrifuging the air and blades above it for centrifuging the water droplets. Below the chambers there is a water collecting tray to receive the descending wash of dusty water and discharge it back into the settling tank. The initial separation of coarse particles from the air is by a dry process in the cyclone, so that an excessive amount of water is not required.
