Title: Control installation for a set of cars of electric train supplied in alternating current
Inventor: GEORGI TODOROV STAIKOV
IPC: H02M7/17
Filed: 1985-06-26
Abstract: The power supply device according to the invention contains an adjustable autotransformer (3) and a train transformer (6) to which are connected a thyristor converter (7), an inductor (8) and a drive motor (9). The driving switch (11) is connected to an information-processing block (12) whose second and third inputs are connected to the train transformer (6) and the drive motor (9). One output from the information-processing block (12) leads to a delay angle determination block (13) for determining the delay angle on the front and rear faces of the voltage. The delay angle determination block (13) is connected to a delay angle change-preset block (14) whose outputs are supplied to a buffer distributor (15) and to a delay angle delimiter (16). The two outputs of the latter are supplied to the preset block (14) and to the buffer distributor (15), to whose third input a second output of the information processing block (12) is supplied. The outputs of the buffer distributor (15) are connected to the position selector (5) and to the control unit (17) for the thyristors of the converter (7) and of a forced-commutation block (10). The power supply device according to the invention facilitates control at high power factor levels. The cos  phi  can be controlled continuously at a value near unity on the basis of the first harmonic of the current; in addition, the arrangement allows a flat phase control, resulting in favourable values of the curvature coefficient.   <IMAGE>

Patent TW-278093-B (TW)
IPC: G03G9/12
Filed: 1993-05-08
Granted: 1996-06-11
Abstract: Encapsulated particles, such as magnetic particles, colored pigments, or carbon black, with high chemical affinity for ink vehicles. The encapsulated particles of this invention are suitable for printing inks, as well as for magnetic recording systems, such as audio and video tapes and magnetic storage disks, when the encapsulated particles are magnetic particles. The encapsulated particles comprise particles having a coating on their surface, said coating comprising in one embodiment an ionomer and in another embodiment, an oil, such as soya oil, and optionally a thixotropic agent, and/or a binder resin. The method of the present invention for making such encapsulated particles avoids the use of volatile organic solvents and provides printing inks and coating compositions comprising such encapsulated particles, that also avoid the use of volatile organic solvents. Inks may be readily formulated without the need for the complicated and expensive flushing process, by simply dispersing the encapsulated colored pigment or carbon black in the desired vehicle.

Title: Conference call participation tracking
Inventor: PENZIAS ARNO ALLAN
IPC: H04M3/56
Filed: 1993-08-20
Granted: 1994-05-11
Abstract: A method and apparatus for tracking participation in a conference call is disclosed. A conference tracker at a first location transmits a status signal to another conference tracker at a second location. The conference tracker at the second location receives the status signal and recognizes it as representative of an attribute of one or more of the parties at the first location. The attribute represented may be the identity of the first location, thereby informing the conference tracker at the second location that the first location remains connected to the conference call. In this manner, the conference tracker may inform a party of the number of connected locations or that a particular location has disconnected. The attribute represented may be the listening party of the location of the speaking party. The attribute represented may be the identity of the speaki ng party, thereby enabling the conference tracker at the second location to determine which party is speaking. Status signals transmitted by each conference tracker may comprise audio pulses of unique frequencies, thereby enabling each conference tracker to determine the origin of each status signal. Consecutive pulses may by used to identify a particular status.

Title: Bed temperature control method and apparatus in a circulating bed reactor
Inventor: FELIX BELIN
IPC: B01J8/32
Filed: 1994-03-24
Granted: 1995-03-21
Abstract: Bed temperature in a circulating fluidized bed (CFB) reactor iscontrolled by varying a recirculation rate of particles collected by a secondary particle separator back to the CFB reactor. Particle storage means, sized to contain sufficient inventory required for bed inventory/temperature control due to fuel/sorbent variations and/or load changes, stores particles collected by the secondary particle separator. The storage means can be either directly below the secondary particle separator or at a remote location. Particles collected by the secondary particle separator rather than by the primary particle separator are preferred due to their smaller size and lower temperature. A bed temperature control system controls the recirculation rate of these particles back to the reactor. Level sensing devices are provided on the storage means. A solids storage level control system that interacts with the bed temperature control system controls the solids inventory in the storage means via a purge system.
