(under subclass 79) Subject matter wherein the beam control means of the space discharge device includes means (e.g., beam deflecting electrodes or coils) for causing the beam to depart from its directed path.
(1) Note. Included in this subclass are systems wherein the beam sweeping deflecting device acts as driven switching device to shock excite a resonant circuit into oscillation, the switching device being driven by an external oscillator. For other shock-excited resonant circuit systems see the search notes below. The driving oscillator in this subclass is claimed in broad terms only, if the driving oscillator is significantly claimed classification is in some preceding subclass, such as the subclasses for the combination of specific oscillator with particular output coupling networks, especially subclasses wherein the output coupling network may include a space discharge device.

74+, for the combination of specific oscillator with particular output coupling networks
75+, wherein the output coupling network may include a space discharge device.
84, for beam tube oscillators of the reflex type wherein the beam is reflected so as to travel in a direction opposite to its initial direction.
128, wherein the switching element is of the gaseous space discharge type. The driving oscillator in this subclass is claimed in broad terms only, if the driving oscillator is significantly claimed classification is in some preceding subclass, 166, wherein the switching element is of the active element type and which system is not provided for in any preceding subclass. The driving oscillator in this subclass is claimed in broad terms only, if the driving oscillator is significantly claimed classification is in some preceding subclass.
