Publication number: 20220091011Abstract: A method comprising passing a fluid through a negative sorting device. The negative sorting device produces a negatively sorted stream of the fluid from which any particles present in the fluid that are above a threshold size have been removed. The negatively sorted stream is analyzed to obtain a measure of a concentration of particles of interest in the negatively sorted stream. The particles of interest have a size that is less than or equal to the threshold size.Type: ApplicationFiled: September 20, 2021Publication date: March 24, 2022Inventors: Siegfried Steltenkamp, Heiner Ophardt, Albrecht Lang

Patent number: 4618782Abstract: A pulse-operated transistor power amplifier having reduced switching times. The interconnected base electrodes of a pair of complementary transistors (T3, T4) are connected to the collector of a prestage transistor (T1). By a resistor (R2), the base electrodes are also connected to one terminal (+V) of the operating voltage source, to which the collector of one (T4) of the two complementary transistors is also connected. The collector of the other transistor (T3) is connected to the other terminal of the operating voltage source, which is linked with the reference potential. The emitters of the complementary transistors are also connected to each other and, by a capacitor (C1), to the base of the final stage. The voltage changes occurring at the collector when the prestage is switched are transferred by one of the two complementary transistors and the capacitor (C1) to the base of the final stage transistor (T5).Type: GrantFiled: August 5, 1983Date of Patent: October 21, 1986Assignee: International Business Machines CorporationInventors: Albrecht Lang, Walter H.
