Title: An Integral Engine and Transmission Unit for a Power Boat
IPC: B63H23/08
Filed: 1978-10-25
Abstract: A transmission for power boats to provide forward and reverse drive is based on a first or driving shaft (10) to which are fixed a belt pulley (11) and a gear (12), and a second or driven shaft (13) which is alternately connectable either with a belt pulley (14) connected by a belt (15) to the pulley (11) on the first shaft (13), or with a gear (16) meshing with the gear (12) on the first shaft (10). The second shaft (13) is coaxial with the pulley (14) and the gear (15) and forward and reverse drive are produced by clutching either the pulley (14) or the gear (16) to the second shaft (13). The driving and driven shafts together with the gears and clutch are located in the engine sump to form an integral engine and transmission unit, whereas the belt drive is located externally of the sump. The output drive shaft (13) is below the level of the engine output shaft so that, for example, a drive line to a boat's propeller may be coupled to the shaft (13) at a smaller angle of inclination to the horizontal than would be the case if it were connected directly to the engine output shaft. <IMAGE>

Title: Process and apparatus for cooling natural gas
IPC: F25B9/06
Filed: 1979-12-03
Abstract: A method of cooling natural gas in a system in which the natural gas contains components other than methane which are separable by dewpoint condensation and the natural gas is available from a source, e.g. a well, at an elevated pressure. In accordance with the present invention, the natural gas is initially expanded in a work-producing expansion turbine to cool the natural gas to a temperature below the dew point of the components to be separated and the portion of the natural gas remaining after separating these components is compressed in a compressor which can in part be driven by the turbine so that at least a portion of the work output of the turbine is at least in some cases utilized for compressing the methane-containing portion which can be forced under pressure into a pipeline. In dependence upon the variable pressure difference between the input of the expansion turbine and the output of the compressor, energy is recovered from the turbine or supplied to the set formed by the turbine and compressor and the compression of the expanded methane-containing portion is effected after heat exchange with the natural gas to be expanded and/or is directly carried out at the expansion temperature.
