Title: Thyristor power supply for TV receiver - has thyristor circuit connected between mains and load and controlled by transistor circuit
Inventor: POLLAK ALFRED
IPC: H02H7/12
Filed: 1977-03-14
Abstract: The thyristor power supply, for a TV receiver, is designed to prevent dangerous voltage spikes appearing at its output when its mains input falls for a short period. The thyristor is connected between the AC mains and the load and is controlled by a control transistor whose base is coupled via a pulse shaper to the mains. The AC voltage is applied via a rectifier (22), a filter (19, 23) and a threshold circuit (24) to the base of the control transistor (8). The time constant of this circuit is such that the control transistor is biased off if only one mains half wave (which turns on the thyristor) is missing or falls below a limit.

Title: Glass or ceramic cell with internal reflecting coating - which is bonded to cell to prevent peeling, esp. when the coating is exposed to corrosive gases in gas analysis appts.
Inventor: FICHTMUELLER GEB KOEHLER ELFRI
IPC: G01N21/03
Filed: 1978-07-03
Abstract: The internal wall of the cell has a reflecting coating of Au or Pt which is bonded in the surface of the cell wall. The cell wall is pref. first coated with Cu which forms a bond with the wall; and then the Cu is covered by the layer, followed by heating to cause diffusion or alloying between the Cu and the Au or Pt. In one pref. process, a thin layer of Cu is formed by vacuum vapour deposition or cathodic sputtering; and the Cu is covered by a colloidal suspension of the noble metal followed by baking to form the bond. In an alternative process, the cell wall is first etched with HF to produce roughness, followed by the direct application of the colloidal suspension of the noble metal onto the wall without using the layer of Cu. Used e.g. in cells for infrared or ultraviolet gas analysis, where corrosive gases are fed through the cell and can cause peeling of the layer by penetration underneath this layer. The invention stops such peeling.

Title: Aperture position direction finding system - uses several aerials ensuring no reduction in sensitivity with increasing beam elevation
Inventor: BAUR KARL PROF DR
IPC: H01Q21/26
Filed: 1978-10-24
Abstract: In order to improve the performance accuracy of a position direction finding multi-element aerial system the antenna is arranged so that there is no signal attenuation when the incoming radio beam has a high elevation. This attribute can be achieved by various arrangements of electric or magnetic dipole aerials. The aerial elements can all be made identical and arranged to have a spherically symmetrical field. The aerial may also be arranged as assemblies of horizontal dipoles in groups separated by a 90 deg. phase displacement. Assemblies using the Adcock system may also be employed. The use of magnetic poles eliminates the need for a quarter wavelength clearance to earth required by an electric dipole. Virtually zero ground clearance can be advantageous where camouflage is necessary.
