Patent EP-0266087-A2 (EP)
Inventor: JOHNSON HOMER K
IPC: B01D63/02
Filed: 1987-10-12
Abstract: Individual fluids (particularly gases) are separated from a stream that contains more than one fluid by passing through a separator device made up of a bundle of hollow fibers (11) fastened into a resin tubesheet (16,19) at each end of the bundle. The fiber bundle is encased in a casing (10) and in the center of the bundle is a perforated, distributor tube (12). Pressure load on one tubesheet (16) is carried by a fixed head (30) in contact with the tubesheet (16). At the other end of the separator device, the tubesheet (19) pressure load is counterbalanced by floating head (22) that utilizes pressure against its backside (24). Pressurized fluid directed into the distributor tube (12) flows into the fiber bundle. The permeate fluids pass through the fiber walls and along the fibers (11) into spaces (28,33) between the tube sheets (16,19) and the fixed and floating heads (30,22) respectively and are carried out of the separator device through outlets (39,40) at each end. The nonpermeate fluids bypass the fibers and are carried out of the separator device through one or more outlets (35) in the casing (10).

Abstract: An optical demodulator in which a local oscillator reference signal and a frequency shift keyed modulated input signal are optically combined by means of an optical multiport junction (e.g. fig. 2). These signals are detected to produce phase-diverse electrical signals (I and Q; A, B and C) at beat frequency and electrically processed (fig. 3 or 4) to provide a demodulated signal. The electrical processing circuitry is phase discriminating and thus produces a signal in which the amplitude is dependent upon the lead/lag phase relationship of the detected signals (I and Q; A, B and C). The local oscillator (3) runs at a frequency midway between the FSK signal tones so that the lead or lag of phase is directly related to the frequency shift coding. The phase discriminant signal processing may be performed using.

Abstract: A transmitter 1 comprises an impeller assembly 7 rotatable by a liquid flow, and an electrical generator 8 having a stator and a rotor arranged to be driven by the impeller assembly 7. The impeller assembly 7 comprises a main impeller portion 9 and a secondary impeller portion 10 angularly displaceable relative to one another about the axis of rotation of the impeller assembly 7 in response to a change in load of the generator 8 so as to vary the pressure drop across the rotating impeller assembly 7. Thus appropriate variation of the load of the generator 8 may be used to control the impeller assembly 7 in such a manner as to transmit pressure signals within the liquid flow. Such a transmitter 1 is particularly suitable for transmitting measurement data to the surface from a measuring instrument at the end of a drill string within a borehole. Furthermore such a transmitter can be constructed so as to be readily retrievable without requiring withdrawal of the drill string from the borehole.

Abstract: A restraint system is provided for restraining a pilot in a safe position during high-acceleration conditions. A stationary harness portion is attached to the pilot's body and haulback straps are connected in a slidable manner to the stationary harness. Under normal conditions, the pilot has some freedom of movement to lean forward or move from side to side. In the event of high acceleration or other emergency conditions, a pair of haulback straps that are slidably attached at the mid-­torso position of the pilot are retracted to bring the entire back of the pilot against the back support of his seat. Lateral support pads positioned at the back and side of the pilot are moved to provide support to the sides, ribs and lumbar regions of the mid-torso and to restrain side-to-side movement of the pilot. The position of the lateral support pads is automatically adjusted according to the size of the pilot.

Abstract: 0 A method and apparatus are disclosed for preserving a minimum or maximum interpacket gap length in an independently clocked data network, typically one following the ANSI-FDDI standard. A smoother is placed downstream of each elastic buffer in the network. The smoother detects the occurrence in an arriving stream of bytes of short preambles, i.e., those having fewer than a threshold number of idle bytes, and inserts some number n a  additional idle bytes into such preambles. Subsequently arriving bytes are delayed by n a  byte clock periods by, in a preferred embodiment, storing them in a FIFO sequence of registers. In order to be available for lengthening other short preambles when 'they arrive, the smoother also detects the arrival of long preambles, i.e., those having more than the threshold number of idle bytes, and deletes a number n d  idle bytes from such long preambles. Deletion is accomplished in the preferred embodiment by reducing the delay of the stream, which in turn is  l accomplished by reducing the length of the FIFO sequence of delay registers by n d  registers. Idle bytes which may have been temporarily stored in idelay registers which are no longer part of the FIFO sequence are discarded. This reduces the extension of the smoother and makes it available for inserting idle bytes into subsequently arriving short preambles. The method and apparatus can be expanded to provide several extended states at each of several different thresholds. It can also be applied in a network requiring a maximum interpacket gap length by providing a normal state and one or more contracted states.

Abstract: A method for removing double metal cyanide complex catalyst from polyether polyols is disclosed which uses alkali metal compounds and phosphorous compounds to precipitate the residual catalyst, which may then be removed by filtration. In one embodiment, a propylene oxide polyol is treated with sodium metal dispersion, capped with ethylene oxide, treated with magnesium silicate, and then filtered to remove at least a portion of the catalyst. Substantially complete catalyst removal is then achieved by treating the polyol with hypophosphorous or phospho­rous acid to precipitate the remaining solubilized double metal cyanide complex catalyst residue, neutralizing the excess acid with magnesium silicate, and filtering.
