Granted: 1987-01-08
Abstract: A Delta-Sigma modulator for one-bit analog to digital conversion of a signal (U(t)), such as a telephone voice channel signal to digital form is disclosed. The voice signal is sampled (1, 3, C<sub>1</sub>) at a rate high compared to the highest voice channel frequency component. Sampled instantaneous signal values are integrated (4, C<sub>3</sub>), re-sampled (10, 12, C<sub>4</sub>) and again integrated (17, C<sub>6</sub>) to reduce encoding noise. Finally, a bi-level sense identifying circuit (19) links the second integrator output to a D type flip-flop (20) providing the one-bit encoder output (b(n)).The sampling and integrator control is effected by switching in a capacitor charge shifting arrangement under clock control and feedback is applied as a capacitor switching program modification (301, 302).

Title: Bag filter for dust laden air - having individual clean air outlets on each bag
IPC: B01D46/04
Filed: 1969-02-11
Abstract: Dust laden gas streams are filtered in bags mounted on frames inside a housing for the dirty gas from which the gas passes into the bag and then leaves via branch. Each bag has an individual clean gas branch which can also be used for purge gas to clean the bag.
