Title: Constant current supply regulation - particularly for telecommunication line repeater amplifiers
IPC: H02M3/338
Filed: 1974-06-12
Abstract: The regulated output of the DC - DC supply is 100 mA over a range of load conditions between 0 and 2.4 kilohms at (+-) 135 volts. The nucleus of the converter is a free running push - pull oscillator using current negative feedback operating at a nominal 17 KHz through a saturable exciting transformer. Control of the output of this oscillator minimises the smoothing required for low frequency outputs resulting from variable frequency types and allows the presence of parasitic oscillation. Control of the oscillator output is from a network sampling the output and providing a DC level for such control. Input supply is 48 volts and final filtering by classical LC methods.

Title: Catamaran type multi-derrick installations - for multiple marine boreholes in depths up to 300 metres
IPC: E21B15/04
Filed: 1975-01-27
Abstract: In a multi-derrick for boreholes prospecting for natural gas and petroleum at sea, in depths up to 300 m, of catamaran type, a superstructure is provided connecting two parallel hulls on which are situated in the axis, derrick towers for one, two, three or four boreholes and crane derricks symmetrically to larboard and starboard, each designed for a borehole. Using a single platform a number of boreholes can be drilled in roughly the same time - e.g. 2 to 3 months - as a single borehole, instead of 15-30 months taken using conventional drilling platforms. Since only one in six boreholes are productive and only one in ten economically viable, the savings in cost cna be substantial if such multiple drilling is used. A smaller number of personnel is required and the number of service vessels can be reduced.
