Filed: 1974-04-11
Abstract: Gas purifcn. process consists of a filter with two vertical screens between which is a bed of granular filter medium so arranged that this bed can be periodically changed, the filtered material removed with the medium and fresh medium introduced. During this exchange no gas is passed through the filter, except a counterflow of air which may be passed through the filter in the opposite direction. The medium can be cleaned and recycled or subjected to further treatment together with the filtered material. Sintered magnetic material can be used. The removal and introduction of the bed is done by gravity. The screens can be parallel to each other or either cylindrical or conical jackets. They can consist of wire meshes, rod frames or lamellae, inwards or outwards inclined like venetian blinds. Several filters can be mounted in parallel, in which case a control device ensures that filter medium changes only occur on one at a time. They can also be arranged in series. Used for separating chemically highly active dusts which are difficult to separate by purely mechanical means. The process permits the additional help of electrostatic or magnetic forces, the bed being periodically renewed.

Title: Electronic musical instrument with reduced wiring and switching - makes use of multiplexing techniques and sequential attack and decay generator
Inventor: JANSEN WINFRIED ING GRAD
IPC: G10H1/20
Filed: 1974-09-18
Abstract: The 61 keys of a five-octave manual are interrogated in turn by a multiplexer, starting from the lowest; the fundamental cycle comprises these 61 time intervals plus a further 47 which represent harmonics. The sequence of 61 intervals can be delayed by up to 12 intervals to provide automatic transposition; it then passes through a flip-flop which separates the bass note from the remainder. The flip-flop is reset at the beginning of each cycle. The bass pulses generate three extra pulses each; the relative amplitudes of the initial and delayed pulses are set by potentiometers (P16, P8,...) to represent the tone colour in use. The outputs of all the channels combine to give a pulse train which a demultiplexer converts into parallel form for the tone generator.
