Title: Semi-submersible structures and method of manufacture thereof
IPC: B63B9/06
Filed: 1975-12-11
Abstract: 1527759 Semi-submersible structures MITSUI SHIPBUILDING & ENG CO Ltd 11 Dec 1975 50767/75 Heading B7A A semi-submersible structure comprises a prefabricated platform 3 and a sub-assembly having lower hulls 1, columns 2 mounted on the hulls 1, horizontal beams 5 interconnecting opposed columns, and platform braces 4 connected to the columns 2, the platform 3 being positioned in the space between the upper ends of the columns 2 while the subassembly is partially submerged and the space is temporarily increased due to resilient deformmation of the beams 5. The sub-assembly is partially submerged by filling with ballast water, whereafter unballasting of the beams 5 causes them to bend and increase the separation of the upper ends of the columns. Once the platform 3 is positioned in the space reballasting of the beams 5 restraightens them so that the platform is clamped between clamping members 200 on the columns 2. Deballasting of the hulls and columns then takes place whereby the sub-assembly is floated upwardly so that guide members 14 engage the lower surface of the platform. Finally further deballasting enables the structure to rise sufficiently to enable connection of the platform 3 to the columns and braces 4.

Title: Control circuit arrangement for a variable-voltage dc-voltage supply means for an inverter
IPC: G05F1/56
Filed: 1974-12-12
Abstract: 1470868 Automatic control of voltage and current DANFOSS AS 12 Dec 1974 [13 Dec 1973] 53823/74 Heading G3R [Also in Division H2] An A.C. motor 8 is supplied by an inverter 7 whose frequency is determined by a control device 9 in dependence on the D.C. input voltage supplied through a rectifier 2 and an electronic switch 3, which is controlled by a control device 4 responsive to the outputs of control elements 11, 12, 13, which respectively determine a different operating condition of the inverter supply corresponding to limitation of the current to a maximum value, maintenance of the current at a desired value and maintenance of the voltage at a desired value, the desired-value current condition being over-ridden when an A.C. component appears in the D.C. input voltage to the inverter, this voltage then being controlled to reduce the A.C. component and so damp undesirable speed oscillations of the motor. It is explained that if the motor 8 is driven at a particular speed, especially a super-synchronous speed, an A.C. voltage component is produced having an approximately constant frequency which is mainly determined by and is of the same order of magnitude as that of the resonant frequency of a filter circuit L1, R2, C2 between members 2, 7, the A.C. component being detected by a band-pass filter 24, Fig. 2 (not shown), whose resistors and capacitors are chosen to allow it to pass a range of medium frequencies. The filter 24 supplies the amplifier 18 of control element 12, which normally maintains the desired value of current in accordance with the output of a comparator 15, the signal of the latter being modified by the output of the filter 24 to adjust the device 4 to vary the D.C. voltage in a manner to counteract the A.C. component. Thus stability is obtained by suitable choice of the amplitude of the A.C. component required to produce a given degree of adjustment. Members 14, 17 of control element 11 limit the current to a maximum value and over-ride the control element 12 for both of its operating conditions, whereby response of the filter 24 to a short circuit between leads 5, 6, causing element 12 to tend to increase the D.C. voltage, is prevented. Members 16, 19 of control element 13 maintain the voltage at a desired value corresponding to a desired motor speed. Elements 11, 12, 13 comprise respective pairs of differential transistor amplifiers inter-connected with further transistors, temperature-equalizing, Zener and other diodes, resistors, capacitors and potentiometers, Fig. 3 (not shown), the operation of the circuits of the various elements being described.
