Title: Method and device for processing a hydrogen sulphide-containing gas, comprising a cooling step for crystallised sulphur removal.
Inventor: SMITH DAVID
IPC: B01D53/86
Filed: 1996-06-12
Abstract: A method and a device for processing a gas containing hydrogen sulphide and sulphur dioxide, wherein the gas is contacted with an organic solvent (1) containing a catalyst in at least one gas/liquid reactor/contactor (2) at a suitable temperature, and the gas (20) substantially free of hydrogen sulphide and sulphur dioxide is recovered. Specifically, a single-phase solvent and sulphur solution (4) is drawn off from the reactor/contactor, a portion thereof is cooled in at least one cooling area (8) to form a suspension of sulphur crystals in the solvent, the crystallised sulphur is separated from the solvent in a separation area (10), and both a sulphur-depleted solvent (14, 15) that is at least partially recycled (1) in the reactor/contactor (2), and sulphur (13), are recovered. The method and device are useful for purifying effluents from Claus units.

Title: Method and apparatus for automatic call distribution.
Inventor: KILANDER SVEN G J
IPC: H04M3/51
Filed: 1998-03-20
Abstract: An automatic call distribution system includes plural call receiving agents associated with a service entity, each of which has conventional telephone access to the public switch telephone network (PSTN). A call center controller (18) initially receives a caller communication from the PSTN intended for the service entity and selects one of the call receiving agents to handle the caller communication based on agent availability. The call center controller (18) coordinates the establishment of a direct communication path for that call between the PSTN and the selected agent which is independent of the call center controller (18). In other words, after setting up the direct call connection, the call center controller is not an intermediary to or otherwise involved in the actual communication between the caller and the agent. Significantly, the call center controller establishes the direct call connection between the incoming call and a selected available call handling agent without the need for a separate private branch exchange (PBX) or automatic call distribution (ACD) switch.

Title: Vessel for raising and conveying offshore platform - uses hydraulic jacks coupled to pressure accumulator to absorb shocks caused by impact
IPC: B63B35/00
Filed: 1978-02-15
Abstract: An offshore structure mounted on the seabed via support support legs is raised and transported to a new location by means of a floating vessel which is equipped with hydraulic jacks to raise the structure. The free ends of the jacks are raised to come into contact with corresponding support points under the structure. To prevent the damage from impact caused by surface swell, the hydraulic fluid supply is coupled, during the raising operation, to an accumulator which enables the impact shock to be hydraulically absorbed. Device eliminates the need for spacing elements used with the traditional semisubmersible type equipment and also prevents impact damage caused by the swell as the two structures are brought into contact.

The compsn. is used esp. for prodn. of foundry cores. The monohydrate is totally miscible with water and consequently provides a very uniform and efficient hardening action. It also provides a higher rate of strength build up, and to a higher level, than has been obtd. with previous ester hardeners.

Title: Shut=off for sea-bed blowout-preventer shaft - has auxiliary piston under borehole pressure, ensuring full closure
IPC: E21B34/00
Filed: 1979-07-23
Abstract: A valve, esp. a ball valve in a train of pipes, has a closing mechanism and an auxiliary, hydraulically-operated mechanism which engages with and displaces the closing mechanism to reinforce its action. The auxiliary mechanism is subjected to the pressure in the flow passage beneath the valve, and/or that outside the housing. The valve is designed for lowering on the train of pipes through a blow-out-preventer shaft at the upper end of an underwater borehole. It comprises a housing with a through passage for a flow, in which a valve body, such as a ball can be moved between an open and a closed position. The valve is moved from the the closed to the open position by a mechanism energised by hydraulic fluid delivered by a pilot line from the surface, and if the pilot pressure falls off, the valve is return to the closed position. Arrangement provides a valve and auxiliary equipment which ensures that the valve can be returned to the fully closed condition even under the most difficult circumstances.

Title: Coal gasification device - includes an element for coal slag removal comprising a water cooled metal e.g. copper casting
IPC: C10J3/08
Filed: 1979-07-27
Abstract: A casting element for use in a coal gasification device comprises a high thermal conductivity metal casting. composed of a metallic pipe having a section for circulating a liquid cooling agent, an upper throat over which the coal slag supplied from the gasification device flows and a central orifice for removing the slag. The surface of the upper throad is angled inwardly and towards the base and is connected to the orifice. The pipe for the cooling agent undergoes no deformation during the casting of any surrounding metal, is enclosed by the casting, forms a conduit for cooling agent near the surface of the throat of the orifice and is spaced from these surfaces by 6.35-38/mm. The pipe ends project beyond the exterior of the casting so as to provide an inlet and outlet for the cooling agent. The element is less subject to chemical attack, to erosion and corrosion than prior elements.

Title: Push=pull output amplifier with output protection - prevents output terminal from being short circuited to either power rail
IPC: H03K19/00
Filed: 1987-09-14
Abstract: The input (IN) to the amplifier is fed via a delay circuit (V1), the push-pull outputs of which are fed to the gates of the push-pull output transistors (T1, T2). In one case (A) the signal is fed directly, but in the other case, it is fed via a sub-circuit (D1). The sub-circuit compares the delayed output with the original input signal, using a NOR gate (L1), and limits the signal to the output transistor (N2) if it is likely to allow a short-circuit condition. The amplifier also has clamping transistors (N8, N9) on the gates of the output transistors, which allow a circuit selection signal (bar CS) to inhibit the output.
