Patent YU-35892-A (YU)
Inventor: CLAUDE BERGMANN
IPC: H02M7/5387
Filed: 1992-04-03
Abstract: Control device for an electric motor with stator winding, in particular an asynchronous motor. A DC voltage (12) is chopped by means of variable frequency and variable mark/space ratio switches (151, 181) in such a way that in each chopping period the intensity of the stator current is dependent on the mark/space ratio. A generator (20) is provided so that this mark/space ratio varies sinusoidally. The chopping frequency is variable in order to permit frequency variation of the sinusoid and hence speed variation of the motor. <IMAGE>

Title: Postupak za impregnaciju i ekspanziju duvana
Inventor: H CHO K
IPC: A24B3/18
Filed: 1992-06-17
Abstract: POSTUPAK ZA IMPREGNACIJU I EKSPANZIJU DUVANA, pronalazak se odnosi na postupak za širenje duvana koji koristi ugljen dioksidni gas. Temperatura i OV sadržaj duvana se podešavaju pre kontaktiranja duvana sa ugljen dioksidnim gasom. Tokom impregnacije sledi se termodinamički tok koji dozvoljava da se kontrolisana količina ugljen dioksidnog gasa kondenzuje na duvanu. Ovj tečni ugljen dioksid isparava tokom snižavanja pritiska podpomažući hladjenje sloja duvana uniformno. Posle impregniranja, duvan se može širiti odmah ili se držati ispod temperature posle provetravanja u suvoj atmosferi za dalje širenje.

Filed: 1975-06-30
Abstract: In apparatus for guiding metal strips (1) over rollers (2) with roller bearings, where eccentric running of the strip is corrected by adjusting the roller axis direction and/or axially displacing the roller, two angularly movable roller bearings (5) are each pushed onto a bush (6) with an eccentric bore and the bushes are fixed onto left and right half axles (4a, 4b), one of which can be twisted. In apparatus for guiding metal strips (1) over rollers (2) with roller bearings, in the case of eccentric running of the strip, the roller axis (3a) is adjusted by a specific angle to the strip transport direction (3b) and/or the roller is axially displaced so that the strip is restored to the correct centered position. The novel features are that two angularly movable roller bearings (5) are each pushed onto a bush (6) with an eccentric bore; the bushes are fixed onto left and right half axles (4a, 4b) with right- and left-handed threads respectively; both half axles are mounted in fixed spindle nuts (7); and one of the half axles (4a) is twisted by a twisting device (8) when necessary for guiding of the strip.

Abstract: Abstract of the Disclosure A plurality of individually actuatable, value weighted digital bistable valve elements in parallel interconnect a fluid source to a fluid receiver.  A linear relationship is preferably maintained between the resultant fluid flow rate from the source to the receiver and the product of a flow rate determinative fluid parameter times the sum of the weighted values of the digital valve elements in the open state.  The fluid parameter is sensed, the states of the digital valve elements are controlled, responsive, and a flow rate representative signal is derived from the states of the valve elements and the fluid parameter.  If the fluid is liquid, the parameter is the square root of the pressure difference across the valve elements, in the absence of cavitating venturis, and is the square root of the difference between the upstream pressure and the vapor pressure of the liquid in the presence of cavitating venturis.  If the fluid is gas, the parameter is the source pressure divided by the square root of the source temperature.  For measurement, the states of the digital valve elements are controlled to maintain the value of tile fluid parameter constant.  For control the states of the digital valve elements are controlled to establish a set point flow rate.

The cooled treated liquid is allowed to settle whereby bacteria in the cooled treated liquid sink in the liquid to leave a layer of sludge above which is a relatively clear liquid.  The sludge and the relatively clear liquid are removed separately before the bacteria in the sludge regain sufficient gas producing activity to raise substantial quantities of solids in the sludge into the relatively clear liquid.

Abstract: ABSTRACT OF THE DISCLOSURE         The valve spool of a three-way pilot valve responds to changes in pressure in a pipeline downstream from a shut-off valve that is biased to close by spring pressure and has a control cylinder to admit pressurized control fluid to open in opposition to the spring pressure.  When the pipeline pressure is in the normal range the valve spool 18 at a normal position where it places the pressurized control fluid in communication with the control cylinder of the shut-off valve to keep the shut-off valve open.  When the pipeline pressure drops below the normal range the valve spool moves in one direction from its normal position to a first alter-nate position to cause the shut-off valve to close and when the pipeline pressure rises above the normal range the valve spool moves in the opposite direction to a second alternate position to cause the shut-off valve to close,  At each of the two alternate positions of the valve spool, it cuts off the source of pressurized fluid and at the same time vents the control cylinder of the shut-off valve to close the shut-off valve.  When the pipeline pressure returns to the normal pressure range, the valve spool returns automatically to its normal position to open the shut-off valve.
