Title: Manufacture of fatty acid esters of sorbitan as surfactants
Inventor: ELLIS JAMES MORGAN HUNTER
IPC: C09K23/34
Filed: 1997-07-30
Abstract: Fatty acid sorbitan esters by direct reaction of sorbitol with fatty acid using a phosphorus oxyacid, including reducing phosphorus oxyacid, particularly phosphorous acid, catalyst system and an alkali or alkali earth metal base, particularly oxide, hydroxide or carbonate, in an acid:base molar ratio of 0.9:1 to 1.7:1, at a catalyst concentration of 1.5 to 30 %, particularly 3 to 12 %, by weight of sorbitol can have lower colour than products of prior commercial bulk processes even without the use of activated carbon and product bleaching typically used previously. The esters can be further reacted with alkylene oxide to make derivatives, particularly polysorbates. The esters and polyalkyleneoxy derivatives are useful surfactants in various applications. Products of low colour made without using activated carbon or bleaching are attractive for personal care applications.

Title: Picture-transmitting remote object inspection system
Inventor: SCHMID JOACHIM
IPC: H04N7/18
Filed: 1997-08-16
Abstract: An image transmitting remote object examination device includes (a) an image recording system at the location of the object to be examined, (b) an observation station located at a distance from the image-recording system for the evaluation of the image and for the remote control of the image recording system, and (c) an intervening, narrow band telecommunications link, by way of which the images taken are transferred to the observation station using image data compression and/or reduction together with the remote control commands to the image system. A system status-determining unit continuously records the overall system status relevant to image transmission, and dependent upon the overall system status, variably controls the image data compression and/or reduction and/or the number of individual telecommunication channels used in a transmission packet. The image quality required for a particular situation, together with the optimal on-line image impression, is thereby obtained.

Title: Implantable defibrillator with improved testing of capability to defibrillate
Inventor: STOTTS LAWRENCE J
IPC: A61N1/39
Filed: 1998-06-10
Abstract: A defibrillator (112) is designed for implantation in a patient and for program-ming certain of its parameters after im-plantation, including energy content of a shock waveform and timing of delivery of the shock waveform. A shock waveform generator (59) of the device is responsive to a trigger signal for timed production of a shock waveform having a programmable shape and energy content designed for ter-minating atrial or ventricular fibrillation (AF or VF) of the patient. A detection circuit (50, 55, 56) processes a sensed car-diac signal of the patient to determine the relative timing of various portions of the cardiac signal, including the P-wave and the T-wave. In a test mode of the device, the energy content of a shock waveform is programmed to a magnitude exceeding the upper limit of vulnerability (ULV) of the patient, and the trigger signal times the delivery of a shock waveform of proper magnitude relative to the occurrence of a selected event in the cardiac signal, such as a cardiac stimulus, the P-wave or QRS complex, for application to the patient's heart coincident with the vulnerable period of a P-wave or a T-wave. The probable ULV of the patient's heart is determined or estimated, the defibrillator is set to deliver a shock of sufficient energy to exceed the probable ULV, and delivery of the shock is initiated into the vulnerable period of the P-wave or T-wave. The defibrillator (12) is selected with the capacity to deliver a shock of maximum energy exceeding the probable ULV by a margin deemed to provide an adequate safety margin for the patient.  The occurrence of the vulnerable period of the P-wave or T-wave is precisely timed from a predetermined event in the patient's cardiac signal.

Title: Method for eliminating ringing during a nuclear magnetic resonance measurement
Inventor: REZA TAHERIAN
IPC: G01V3/32
Filed: 1999-05-27
Abstract: The present invention relates generally to a method for eliminating ringing while measuring nuclear magnetic resonance properties of an earth formation traversed by a borehole. The measurement can be made while drilling or using a wireline tool.  During a first time period of a single pulse sequence, the measurement includes the desired spin-echoes and the undesired effects, that is, ringing, measurement noise, and baseline shift. During a second time period of the single pulse sequence, the spin-echoes are eliminated but not the undesired effects. Using the signal collected during the second time period, the signals measured during the first time period are corrected to eliminate the ringing component, measurement noise, and baseline shift.

Abstract: Multipotent neuroepithelial stem cells and lineage-restricted oligodendrocyte-astrocyte precursor cells are described. The neuroepithelial stem cells are capable of self-renewal and of differentiation into neurons, astrocytes, and oligodendrocytes. The oligodendrocyte-astrocyte precursor cells are derived from neuroepithelial stem cells, are capable of self-renewal, and can differentiate into oligodendrocytes and astrocytes, but not neurons. Methods of generating, isolating, and culturing such neuroepithelial stem cells and oligodendrocyte-astrocyte precursor cells are also disclosed. A method of generating neural crest stem cells involves inducing neuroepithelial stem cells to differentiate in vitro into neural crest stem cells. Differentiation can be induced by replating the cells on laminin, withdrawing mitogens, or adding dorsalizing agents to the growth medium. Derivatives of the peripheral nervous system can be generated by inducing the neural crest stem cells to differentiate in vitro.
