Abstract: The present invention concerns a procedure for removing gases from a distilling apparatus (10). In the procedure, the effluent water is caused to flow from the distilling apparatus (10) along an effluent line (19) to an effluent heat exchanger (13) for recovering the heat contained in the effluent. The feed water is arranged to flow along a first branch line (14a) through a distillate heat exchanger (12) and along a second branch line (14b) through the effluent heat exchanger (13) to the purpose of preheating the feed water. The mixture of distillate, vapour and gases is conducted from the distilling apparatus (10) along a flow line (16) to a degassing heat exchanger (11), where the heat contained in the mixture is recovered. The recovered heat is utilized in preheating the feed water by conducting the feed water after the distillate heat exchanger (12) and the effluent heat exchanger (13) along a header line (15) through the degassing heat exchanger (11), and further by a tubular connector (20) into the distilling apparatus (10). The gases are allowed to escape from the degassing heat exchanger (11) through a gas venting hole (17) into the environment. The mixture flow is condensed in the degassing heat exchanger (11) to distillate, and the distillate is conducted from the lower part of the degassing heat exchanger (11) along a distillate line (18) to the distillate heat exchanger (12).

Abstract: A process for preparing a rolled pastry product in which a sheet of pastry material advancing on a conveyor belt is cut and folded into discrete pieces of a predetermined size and then rolled. The cutting and folding operation is carried out by an oscillating knife positioned above the conveyor belt which has a cutting edge extending laterally across the width of the conveyor belt, and which immediately after contacting and cutting through the advancing pastry sheet by means of its cutting edge, ascends and rotates in a direction such that the motional vector of the cutting edge is counter to the conveying direction thereby causing the forward edge of the pastry sheet to be lifted up and folded over. The knife then descends and rotates in the reverse direction so that the cutting edge contacts and cuts through the advancing pastry sheet behind the folded portion to separate a folded piece from the remainder of the pastry sheet.

Abstract: Processes of reducing the inorganic sulfur-containing acid and the low equivalent weight organic sulfonic acid content of an acid mass comprising organic sulfonic components and inorganic sulfonating agent contaminants are described. In general, the process comprises the steps of (a) treating the acid mass with ammonia in the presence of water to neutralize the acids in said acid mass and to form a mixture containing the ammonium salts of said acids, (b) allowing separation of the mixture to provide a lower aqueous phase containing water-soluble ammonium salts and an upper phase comprising the oleophilic alcohol and ammonium salts of the organic sulfonic acids, and (c) recovering at least a portion of said upper phase. The efficiency of the reduction of undesirable materials from the acid mass can be increased by subjecting the recovered upper phase to additional water extractions in the presence of the oleophilic alcohol. The ammonium salts of the organic sulfonic acids recovered by the above process can be converted to oil-soluble metal salts by reacting said ammonium salts with a basically reacting metal compound in such amounts and under such conditions as to form metal salts of said organic sulfonic acids. The metals salts prepared in this manner may be neutral metal salts or highly basic metal salts. The neutral and metal basic salts are useful in a variety of applications including lubricants and fuels.

Date Dec. 1, 1988.A reversing device of a jet propulsion assembly for ships. The jet propulsion assembly includes a steering means connected to the outlet of a pump, for steering the driving water jet, the steering means including two flaps for reversing the driving water jet. An actuator pivots a first flap downwards around a first bearing across the water jet, at the same time as link arms, which are journalled between the front edges of the first flap and second flap, swing the second flap around a second bearing. The rear portion of the second flap is thereby raised towards the water jet and encounters the inner side of the first flap in such a way that both flaps shut off the passage rearwards and divert the water jet obliquely downwards/forwards. The two flap bearing points on the steering means together with the link arm bearing points on the two flaps provide an equilibrium of forces between the actuator pressure on the first flap and water jet pressure on both flaps, under the condition that a reduction of the pressure on the actuator results in the first flap being swung upwards by the water pressure.

Title: Controller for starting and stopping electric motors
Inventor: MERRISON JOHN C
IPC: H02P1/28
Filed: 1990-10-24
Granted: 2000-01-11
Abstract: A three-phase motor is operated by a controller having sets of thyristors which when triggered switch electricity from each phase of a supply to the motor. The controller measures the interval .PHI. between when the voltage and the current for one phase to the motor make zero crossings and measures the interval .gamma. that the thyristor are non-conductive during half-cycle of the voltage for the one phase. A control angle .THETA. is calculated according to the equation .THETA. = .PHI. + K.gamma., where K is a positive number. The control angle .THETA. is compared to a reference value to derive an error value. The times at which the thyristors are triggered is controlled in response to the error value. To start the motor, the reference value is gradually decreased to trigger the thyristors progressively earlier during each half cycle of the supply voltage. To stop the motor, the reference value is gradually increased to trigger the thyristors progressively later during each half cycle of the supply voltage.

Title: Optical amplifier
Inventor: THIJS PETRUS JOHANNES ADRIANUS
IPC: H01S5/10
Filed: 1991-07-31
Granted: 2002-01-22
Abstract: The invention relates to an optical amplifier with a semiconductor body comprising a layer structure grown on a substrate, with an active layer between two cladding layers, a strip-shaped amplification region being bounded by two end faces of low reflection which form the input and output faces for the radiation to be amplified. The active layer comprises a number of quantum well (QW) layers with direct band transition, and separated by barrier layers of a different semiconductor material, a first portion of which QW layers is under tensile stress. Such amplifiers are used inter alia in optical glass fibre communication systems.      The known amplifier is owing to the tensile stress, less sensitive to polarization but the amplification can not be obtained at a minimal current.      According to the invention, another portion of the layers forming part of the active layer is under compressive stress. Owing to the compressive stress present locally in the amplification region, the TE-mode is more strongly amplified there than the TM-mode, while in the tensile portion of the amplification region the TM-mode is more strongly amplified than the TE-mode. This enables realisation of a polarization insensitive .amplifier with higher stress and thus with a large amplification at a relatively low current.      In one embodiment, both portions of QW layers are within one stack of layers containing the amplification region. In another embodiment both portions are positioned in different stacks that are located next to each other each adjoining a different endzone of the amplification region. In the latter, independent adjustment of the TE and TM amplification profiles is possible.
