Title: Heating device for liquids, particularly liquid fuels
Inventor: BUNGAY MICHAEL RONALD
IPC: F02N19/04
Filed: 1983-01-10
Abstract: A heating device for liquids more particularly liquid fuel comprises a pair of slab-like bodies 11 spaced by a gasket 12. Each body 11 defines a flow path for liquid, one end of each flow path terminates in a pair of aligned apertures 14 in the body and through which extends a bolt 16, the bolt defining inlet and outlet flow passages. The other ends of the flow passages are interconnected so that the two flow passages are in series. Each body has a plate 20 carrying a foil heating element, located against a face 18 thereof, an insulating sheet 19 being located between the heating element and the face. The plate 20 is located against a clamping sheet 24 which is clamped to the body. When electric current is passed through the heating elements the bodies become heated and heat the fuel in the flow passage. Means is provided to control the temperature of the bodies by controlling the current flow in the heating elements. <IMAGE>

Title: A method of coupling an electric machine to another machine
Inventor: OLIVARI ANTE
IPC: H02K15/16
Filed: 1983-10-28
Abstract: A threaded eyebolt (1) is arranged at one end of a first electric machine and engages both the stator cover (2) and the rotor shaft (3) of the machine such that relative movement between the rotor and stator of the machine is prevented. A second machine is arranged vertically and the first machine is suspended over and aligned with the second machine by way of the eyebolt (1). The eyebolt (1) is then partially unscrewed to release the rotor of the first machine such that its flange (4) can be coupled to a flanged flywheel of the second machine. The stator of the first machine could be raised by way of the eyebolt (1) to permit the coupling of the rotor to be achieved easily. Thereafter, the stator is lowered and its flange is coupled to a corresponding flange of the second machine. The coupled machines can then be rotated to extend horizontally. <IMAGE>

Title: Extracting natural gas streams with physical solvents
Inventor: MEHRA YUV R
IPC: C10G5/04
Filed: 1983-12-16
Abstract: A continuous process is described for extracting a raw inlet natural gas stream with a physical solvent, flashing the rich solvent, and selectively rejecting a consecutive molecular weight string of C1-C4 components from at least a portion of the off-gas flashed from the rich solvent stream or streams. The process produces: (a) a liquid C2 + hydrocarbon product, having a composition that is selectively adjustable to substantially any selected degree as the liquid market price for a low molecular weight C2-C4 component or string of components falls below the fuel price thereof, and (b) a sweet, dry residue natural gas stream of pipeline quality which includes the rejected C1-C4 hydrocarbon components. If the liquid market price of the C3 and/or C4 components is below the fuel price thereof while the liquid market price of a lower molecular weight component is not, the C1-C4 components are further extracted, flashed, and split before returning the desirably priced component or components to the liquid product. <IMAGE>

Title: Apparatus for analysing sailboat performance
Inventor: SCARLETT JOHN JAMES MORVEN
IPC: G01C21/20
Filed: 1985-02-14
Abstract: The performance of a yacht is monitored by measuring the apparent wind angle and the magnetic heading by suitable means 1,3, and determining the true wind angle from these measurements. The apparent wind speed and boat speed are also measured by suitable means 2,5, and these measurements are used to determine the true wind speed. The wind pressure is then determined from the true wind speed and the ambient temperature measured by suitable means 4. The calculated values for the true wind angle, the boat speed, and the wind pressure are supplied to a processor 9 which determines the maximum boat speed for each of a series of wind angles for various values of the wind pressure. The data resulting from such processing is supplied to a polar plotting device 10 which plots a series of polar graphs of maximum boat speed against wind angle. <IMAGE>
