Patent CA-1049612-A (CA)
Inventor: EMELYANOV VIKTOR I
IPC: H02M5/42

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosure is made of a rectifier-inverter system of a converter substation intended for the transmission of energy between a.c. networks having different frequencies, which system comprises one or more pairs of rectifier and inverter converters connected to a common d.c. circuit.     According to the invention, the poles of at least one rec-tifier or inverted converter are connected to a protective ground ing via resistor-capacitor elements.     The absence of direct contact with the ground in the d.c. circuit rules out the possibility of a low-resistance closed circuit being formed as a result of a short-circuit earthing at any point of the d.c. circuit. This reduces the voltage across the insulation with respect to the ground at each pole of all the converters and diminishes the steady voltage component across the insulation with respect to the ground of transformer valve windings.

Abstract: GASTROINTESTINAL ASPIRATOR PUMP                   SYSTEM AND METHOD            Abstract of the Disclosure The system includes pumps for supplying negative and positive air pressure (with respect to atmospheric air) air to the negative and positive lumens, respectively, of a multilumen tube. The lumens are separated from each other by a partition wall within the tube.  The negative air pressure lumen has a plurality of apertures distributed along the outer wall of the end portion of the tube and the positive air pressure lumen has an aperture in the partition wall adjacent each of the aforesaid apertures.  The negative air pressure is steadily applied, while the positive air pressure is supplied in periodic pulses.  The rate at which air passes into the positive air pressure lumen is visually indicated by bubbling the air through a transparent walled vessel and the rate at which air passes out through the negative air pressure lumen is indicated by bubbling the air through an-other transparent walled vessel.  The positive air pressure is limited by an air relief valve to a safe value.  An air inlet is provided to admit air into the positive air pressure lumen whenever its pressure drops below atmospheric air pressure.  The dimensions of the tube, and the various other values of pressures, times, velocity of flow are given which permit the system to be operated with a novel method for evacuating an enclosed viscus and for releasing blockages in the tube.
