Publication number: 20190185278Abstract: A method and apparatus that reduce release of dust generated during rotary dumping of rail cars in a dumping facility. The method includes removing dust laden air from a space bounded by a backside airflow diverter, a rotational frame, a first baffle and a second baffle while the rotational frame is rotating with a rail car by drawing the dust laden air through a secondary air intake that passes through the backside airflow diverter into a backside hood. A dust control apparatus includes a diverter, overlying a backside hood having a concave curved upper surface; and at least one secondary air intake positioned to pass through the diverter being located approximately where pressure in the backside hood remains neutral or negative relative to a pressure even there is a transient increase in air pressure in a lower portion of the backside hood.Type: ApplicationFiled: January 16, 2019Publication date: June 20, 2019Inventors: Michael R. Harris, Jason Santers

Patent number: 7916872Abstract: A low-power, software based modulator that is used to transfer text data from an auxiliary audio device to an FM radio receiver includes a processor that receives the text data to be transmitted to the FM receiver, processes the data as an RDS signal or converts the text data to speech and then combines the processed data signal with an FM audio signal that is sent to the FM receiver. In one embodiment, the auxiliary audio device is a CD or CD-MP3 player and the software-based modulator is implemented on the control processor or DSP of the device. The FM encoder that produces the FM encoded audio signal may be a separate analog encoder or may also be implemented in the control processor of the auxiliary audio device.Type: GrantFiled: September 30, 2003Date of Patent: March 29, 2011Assignee: Lee Capital LLCInventor: Michael R.
