Title: Recovering volatile hydrocarbons when loading an oil tank
Inventor: DAVIES SIMON
IPC: B01D53/14
Filed: 1995-05-05
Abstract: Volatile organic components (VOC) such as low hydrocarbons are recovered when loading an oil tank by compressing the gases issuing from the tank and subjecting them to gas-liquid contact, eg with the crude oil being loaded, whereby the hydrocarbons are absorbed and the remaining inert gases are vented. The recovered gases may be recycled to the tank or recovered separately. Contacting is achieved with a static or rotary device, in particular a biphase rotary separator turbine. <IMAGE>

Title: A machine for preparing and planting cuttings
Inventor: TURTON JOHN SAMUEL
IPC: A01C11/00
Filed: 1995-06-02
Abstract: A system (Figure 1) whereby a towed machine for the successive preparation and planting of vegetative cuttings embodied a mechanism driven by a double acting hydraulic cylinder 6 . Such a cylinder is controlled by electrical switches 25, 27, 29 which activate solenoids to operate hydraulic valves 19, 20. From a "dwell" position of the mechanism outward and return motions of the piston rod cause corresponding related motions of a sliding block 4 on which is mounted equipment for the preparation and planting of cuttings and which is driven along constraining slidebars 45 , mounted on an inclined frame 1, in a downwards and rearwards direction followed by return to the "dwell" position. This sequence is initiated by the closure of "trigger" switch 29. The distance travelled by the sliding block depends on the lengths and positions of control rods 26 and 28 fixed to the sliding block and operating electrical switches 25, 27 , such lengths being chosen to give the required distance of travel.

Title: Pressure-energized sealing rings
Inventor: SWENSEN JEFFREY E
IPC: F01D11/00
Filed: 1995-09-07
Abstract: A pressure-energized sealing ring (10) having a bight portion (12), a first leg portion (14) and a second leg portion (16) for providing a fluid-tight seal between a pair of components. The first and second leg portions include a curved section (42, 52) having first and second sealing surfaces (46, 56). The sealing surfaces are spaced from the free ends of the leg portion. The free ends (44, 54) of the leg portions are positioned between the bight portion and the sealing surfaces so that the ends of the seal are located in the area of low pressure. Accordingly, when sealing ring is a multi-ply seal, the free ends of the seal are positioned in the low pressure area so that the high pressure does not separate the seal. The curved sections of the leg portions and the curve of the bight portion securely couple the plies together without welding. Preferably, the plies are connected together and in intimate contact at their interfaces therebetween. In some embodiments, the leg portions include planar or crowned sections so that the sealing surfaces are faced farther from the bight portions to lower the contact force and stress level in the bight portion. In other embodiments, the bight portion has at least one convolution. Still in other embodiments, the sealing ring is arranged for an externally pressurized-type application. <IMAGE>

Title: Linear high efficiency rf amplifier using ac biasing signal added to input with means for removing the biasing signal from the output
Inventor: WALKER NICHOLAS
IPC: H03F1/32
Filed: 1999-07-07
Abstract: An amplifier is provided which uses AC biasing to linearise the operation of the amplifier whilst maintaining good DC power efficiency. In order to prevent the AC biasing signal from being reflected back into the amplifier 14, 16 from an output filter 6 attached to the output of the amplifier, thereby reducing the lifetimes of the amplifier's active devices, the AC biasing signal is coupled with the input signal in a quadrature coupler 10 before being fed to the amplifier. A similar quadrature coupler 12 then receives the amplified signal, and acts to reject the AC biasing signal from the amplified input signal, so that only the amplified input signal is fed to the output filter. The rejected AC biasing signal is then dissipated in a reject load 8 attached to another output port of the output quadrature coupler.
