Patent EP-0298610-A2 (EP)
Inventor: PASPEK STEPHEN C
IPC: B01D12/00
Filed: 1988-06-09
Abstract: The present invention provides a facile method of oil removal from an oil-water emulsion containing suspended solid particulates. In general, the method utilizes a volatile solvent which is liquefied under pressure and forms a two-phase system when in contact with the emulsion. More particularly, the process of the present invention comprises the steps of
     (A) introducing said emulsion into a vessel in an extraction system,   (B) pressurizing the vessel with a volatile hydrocarbon whereby said volatile hydrocarbon is in the liquefied state and forms a two-phase system with said emulsion,   (C) maintaining said pressure for a period of time sufficient to effect the replacement of at least some of the oil in the emulsion phase with said volatile hydrocarbon, the replaced oil being dissolved in the volatile hydrocarbon phase,   (D) withdrawing at least a portion of said oil-containing hydrocarbon phase while maintaining the pressure on the two-phase system,   (E) reducing the pressure on the two-phase system whereby hydrocarbon dissolved in the emulsion is vaporized, and the emulsion separates into a water phase and an oil phase, and   (F) recovering the oil phase from the water phase.

Abstract: Pivot for a covering which can be moved along a curved path and is divided by the pivots, transversely with respect to the direction of movement, into segments which can be swivelled relative to one another about the pivot axis. The end faces of two adjacent segments are in each case formed in such a way that the gap present between these does not exceed a predetermined maximum value during the swivelling of the segments. The construction according to the invention with a two-part segment shell and a plastic supporting strip which bears a seal and is in each case arranged on the end faces of the segments permits the use of an efficient manufacturing process, the hollow space of the segments preferably being filled with a PUR foam system. <IMAGE>

Abstract: A process for readily isolating and recovering highly pure erythritol at a high crystallization yield from an erythritol-containing culture medium, which contains erythritol together with various impurities such as salts, coloring materials and polysaccharides, through chromatographic separation with the use of a strongly acidic cation exchange resin. The process of the present invention can be continuously operated, since the lowered separation capability of said cation exchange resin can be readily restored by treating the same with a warm alkali solution.

Abstract: The invention provides a combination in a SLIC for telecommunication applications of ac impedance synthesis, eg. raising the impedance of battery feed resistances by feedback techniques; in combination with real battery feed resistors and a dc blocked transformer. A dc blocked transformer (16) is coupled to line current feed resistors (22; 24) and a feedback loop network to synthesize the desired input impedance, such that the feedback network incorporates both positive and negative feedback. A loop stabilizing resistor is used in shunt with the dc blocked transformer secondary to reduce gain peaking and phase shift. The transformer is an integral part of the feedback loop, and one of the outputs of the solid state circuitry are directly connected to the subscriber line, thereby eliminating the problem of lightning induced transients, in that the output stages of the solid-state operational amplifier circuitry of the invention are transformer isolated from the subscriber line, and are coupled to the subscriber line through high impedances providing high resistance isolation.

Abstract: To control a plurality of apparatuses (6a-6z), the apparatuses and a master control unit (2) having a communication unit are all connected for intercommunication in series through communication lines (10). One of the communication unit is used for exchanging messages between the master control unit and the apparatuses. Messages can transfer from one apparatus to another one in sequence. In another embodiment, the last apparatus is further connected with another communication unit of the master control unit, making a looped communication circuit. Therefore, messages sent out from one of the communication units of the master control unit can be received by the other communication unit to monitor the intercommunication. If a communication line is disconnected, messages can be also sent from another communication unit of the master control unit in reverse direction, making it possible to communicate with all of the apparatuses.
