Abstract: 1493652 Phase shifting OTDEL ENERGETICHE KIBERNE AKAD NAUK MOLDAV SSR 22 July 1975 [22 July 1974 (4)] 30665/75 Heading H2F A phase shifter comprises at least two threephase multi winding transformers α, # each having primary windings W 1 α, W 1 # connected in series for each phase and control windings Wcα, Wc#, the first three-phase transfomer α being provided with two groups of secondary windings W 2 α, W<SP>1</SP> 2 α and the second transformer # consisting of a single group of windings W 2 #, the control windings being connected to respective switching devices 3, 4 which are able to short the control windings to adjust the phase angle between the sets of output voltages E<SP>1</SP> A -E<SP>1</SP> C  and E<SP>11</SP> A -E<SP>11</SP> C . The switching devices consist of opposed thyristors (7, 8), Fig. 17 (not shown) and diodes (9, 10) so that when both the switching devices are off the phase angle between the sets of output voltages is 60 degrees. When the device 3 is switched on to short circuit the control windings for the first transformer and the device 4 is off, the phase angle is zero and the transformer system supplies low power loads. When the device 4 is switched on to short circuit the control windings of the second transformer and the device 3 is off, the phase angle between the sets of output voltages is 120 degrees and the transformer system supplies high power loads. In a modification the windings W 2 # are delta connected to give phase shifts of 90 and 180 degrees and the first transformer may have a third group of secondary windings.

Abstract: An immersed electromagnetic torque motor having a movable flapper is protected against the accumulation of contamination in magnetic gaps of the motor and the resulting jamming of the motor by coating the motor with a lacquer or other fluid-impermeable material and mounting the motor in a blind fluid chamber from which the flapper projects. An aperture is provided in the coating at a low flux area on the exterior of the motor to admit the immersing fluid for purposes of mechanical damping and, at the same time, to restrict the migration of fluid and contaminants toward magnetic gaps within the torque motor.

Abstract: The table top (1) is provided with an edge guard (2), a conventional plastic edge band. It engages over the top and bottom edge of the table top (1) with a strip (3) and (4). The edge guard (2) can have a downwardly projecting web which projects from the lower table-top plane with a slight outward and downward divergence. The table top (1) is made of natural wood. A plastic coating (7) is applied to its top side and bottom side. With the application of a sufficiently high pressure and corresponding temperature, it is achieved that the low-viscosity plastic penetrates relatively deeply into the edge zone of the table top, all pores being completely filled and reliably sealed against the penetration of moisture. An edge guard is thereby provided which encloses and seals the table top in such a manner that moisture can no longer pass under the edge guard and penetrate into the cut surfaces of the table top. <IMAGE>

Abstract: A cover arrangement for a container, for example for a ship's hatchway, has a cover element which is hinged at one side. The hinging includes a lost motion connection, which allows automatic engagement and disengagement of mutually engageable member at that side for cleating. This is achieved by movement of the cover element in its closed position within the scope of the lost motion connection. The cover element may include other automatic cleating member on other sides; the cleating is preferably effected by final closing movement of the cover element under gravity.

Abstract: A method of and an apparatus for obtaining better utilization of a fuel 1a, especially a solid fuel, in which the fuel is subjected to a primary combustion in a primary combustion chamber 1b and the primary flue gas with entrained particles of combustible material flows through a restricted outlet 1c into an after-combustion chamber 2. In the chamber 2 the particles are separated from the flue gas by a combination of sedimentation, resulting from the expansion of the flue gas into the larger flow cross section of the chamber 2, impingement-baffle separation and of direction-change separation, the two latter forms of separation being caused by impingement of the flue gas against a baffle 4 disposed above an outlet 3 to the chimney or stack. An inclined wall 6 in a dead space or flow shadow region in the chamber 2 serves to guide the collected particles back to a combustion region, at which a burner 7 is optionally provided. <IMAGE>

Abstract: The system has the external main operating component of the electronic equipment, used for adjustment and control of its various functions, connected to a microprocessor which is pre-programmed to accept the effect of the external control in a specific sequence. The microprocessor is connected to a relay or other kind of switching device permitting 'on' and 'off' connection of at least one specific circuit in the electronic equipment, and is fed with current irrespective of the 'on'/'off' status of the equipment. A predetermined time after switching 'off' or fall-away of voltage feed, the electronic circuit is disconnected, and it can only be reconnected when the main operating component is manoeuvred in accordance with a given sequence. Where the sequence is fed in incorrectly, a time monitored period occurs during which new code sequences are not accepted, and where subsequently repeated feeds of erroneous sequences occur, this time monitored period is prolonged.
