Title: Digital switching system in computer controlled exchange - has input and output queuing facilities, and identification of input and output lines and channels
Inventor: HOWARD GRAHAM
IPC: H04Q11/04
Filed: 1977-04-25
Abstract: A digital switching network build connecting paths between any channel out of any number of incoming time division multiplex exchange lines, and any channel in any number of outgoing time division multiplex exchange lines, controlled by path connection devices in the switching network. Control devices have input waiting queues and output waiting queues which store in order of arrival processor input and output signals. The control devices process asynchronously each output signal, and use the switching network connection control devices in order to process a switching network path. An input signal is generated in the input waiting queue at the end of such operation, which shows the process steps carried out during processing of each output signal. Each output signal has a switching network identification information showing only the identity of incoming and outgoing lines and channels, concerning the switching network path.

Title: Electromechanical contact breaker and circuit switch - for telephone systems, is lever-operated, has elastic foam compression pads and is housed in transparent glass or PMMA casing
Inventor: LENZ KURT
IPC: H01H1/24

Title: Laser for electromagnetic energy of limited width and time period - injects electron beam pulse into middle of electromagnetic beam for conversion into oscillations
Inventor: HORA HEINRICH PROF DR
IPC: H01S3/09
Filed: 1978-07-21
Abstract: The device provides crossing of a laser beam of any arbitrary wavelength by free electrons in vacuum.

The braking of the electrons, injected into the laser beam, is utilised in such manner that the braking energy is taken up in the laser beam as a potential field energy. After injecting of the electrons into the electromagnetic beam, the electron kinetic energy at right angles to the electromagnetic energy converts the electron beam energy into an oscillation energy in an electromagnetic field corresp. to the beam dia.
