Abstract: Method, apparatus, and films, related to coextrusion of heat-sensitive polymer materials, The sensitive melt stream element (12) is encapsulated in a second polymeric melt stream element (16). Transport means (363 is preferably employed between the encapsulating means (20) and the die (42). A third melt stream element (68) is joined to one or both opposing surfaces (70) of the second melt stream element (16) between the encapsulating means (20) and the die (42). In the die (42) the encapsulated melt stream element (12) becomes an interior layer (46) between encapsulating layers (48A, 48B) derived from the second melt stream element (16). The third melt stream element (68) forms layers (72, 74) positioned outwardly of the encapsulating layers (48A, 48B). The positioning, on the interior of the extrudate, of edges (54) of layer (46) is adjusterd independently of the combined thicknesses of a layer derived from the third melt stream element (68) and an adjacent layer (48).

Title: Detection of fracturing events using derivatives of fracturing pressures
Inventor: AYOUB JOSEPH A
IPC: E21B43/26
Filed: 1991-09-06
Abstract: ABSTRACT OF THE DISCLOSURE        In accordance with illustrative embodiments of the present invention, a method of determining fracture behavior from downhole pressure measurements that are made during a hydraulic well fracturing operation includes pumping fracturing fluids at a constant rate under high pressure against a formation to create fractures therein, and obtaining measurements representative of downhole pressures as pumping progresses,  The logarithmic derivatives of such pressure measurements are used to determine the type of fracture behavior, as well as the onset of screenout where the fracturing fluid carries a proppant.  In-situ stress or closure pressure also can be determined by finding a value thereof which makes a logarithmic net pressure plot have the same slope as the logarithmic plot of the values of the pressure derivatives.

Title: N,n'-disubstituted guanidines and their use as excitatory amino acid antagonists
Inventor: WEBER ECKARD
IPC: C07C279/18
Filed: 1991-03-04
Abstract: Disubstituted guanidines, e.g., bis-1,3-(o-isopropylphenyl) guanidine, bis-1, 3-(m-isopropylphenyl) guanidine, bis-1,3-(1-naphthyl)guanidine, bis-1,3-(m-methoxyphenyl)guanidine, N-(1-naphthyl)-N'-(o-iodophenyl)-guanidine, N-(1-naphthyl)-N'-(m-ethylphenyl)guanidine, and N-(1-naphthyl)-N'-(o-isopropylphenyl)guanidine, exhibit a high binding affinity to phencyclidine (PCP) receptors. These N,N'-disubstituted guanidine derivatives act as non-competitive inhibitors of glutamate-induced responses generated via the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert a neuroprotective property and are useful in the therapeutic treatment of neuronal loss in hypoxia, hypoglycemia, brain or spinal cord ischemia, brain or spinal cord trauma, as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.

Abstract: The control apparatus of the present invention is used for a washing machine in which a photosensor having a light emitting element and a light receiving element opposite thereto, detects the degree of light transmission in washing water, and in which, based on variations of the degree of light transmission in washing water thus detected, the respective steps of washing, rinsing and draining are controlled.  Correction is made such that the photosensor presents a predetermined sensitivity to set a current which flows in the light emitting element, after which a washing operation is started.  After drainage, when the next water supply operation is started and the level of water thus supplied reaches a predetermined level within a predetermined period of time, it is judged that washing water used at the previous washing remains in a washing tank.  Then, control is made such that no adjustment is made of the sensitivity of the photosensor and a standard current flows in the light emitting element.  Thereafter, a washing operation is started.  Thus, the control apparatus of the present invention is adapted such that no influence is exerted upon the degree of washing by variations of the characteristics of light emitting elements and light receiving elements.
