Title: Method of formation of polymeric fiber matrices and a polymeric fiber matrice
Inventor: TICHONOVAS MARTYNAS
IPC: D01D5/00
Filed: 2021-12-10
Abstract: The invention is a method for forming a polymeric fibrous matrix comprising dosing a polymer filament, heating and melting the polymer filament, directing the molten polymer from bottom to top in an electric field, and forming the polymer matrix on a substrate. The polymeric fiber matrix is formed in a sealed, controlled climate chamber. The heating and temperature measurement of a heating and melting head is performed by supplying voltage from low voltage supply portion of a power supply. An electric field is generated between the heating and melting head having positive potential and grounded base of the polymeric fiber matrix by supplying high voltage from high voltage supply portion of the power supply. The high voltage supply area in the heating and melting head is isolated from the heating and melting head heating element, which is supplied with low voltage, and from all other elements of the polymeric fiber matrix forming apparatus.

Inventor: STONE CHARLES L JR
IPC: A61B5/375
Filed: 1988-08-15
Abstract: A system for mapping and/or displaying spatio-temporal features of underlying event-related neural activity involves measuring the event-related evoked potential values at a limited number of points over the region or interest (30), deriving a first grid of potential values at points over the area of interest representing at least a Kriging-type of spatial statistical interpolation (36), and using the first grid to derive for the region of interest a second grid of points of current density values by a Laplacian conversion (40). A plurality of second grids of current density values spaced apart in time are derived and displayed on a monitor in cartoon-type fashion to provide a cartoon-type display of the features of the event-related evoked response over the region of interest varying with time. Various other displays are possible for highlighting specific features.

Abstract: Thiophene derivatives with an optionally substituted amino group on the thiophene ring are prepared by dehydrogenation of dihydrothiophenes which are substituted in the same manner as the desired thiophene derivatives, using H2O2, the dihydrothiophenes being reacted in a first reaction step with H2O2 in neutral medium to give the corresponding sulphoxides, and, in the second reaction step, these are then rearranged with acid to give the thiophene derivatives. The dihydrothiophene-1-oxides which are formed in this process as intermediates are novel compounds. They, and equally the thiophene derivatives obtained from them by rearrangement with acid, are intermediates mainly in the crop protection agent sector and pharmaceutical sector.

The peptoids can be synthesized in large numbers so as to provide libraries of peptoids which can be screened in order to isolate peptoids of desired biological activity. Certain peptoids are designed to mimic as closely as possible the activity of known proteins. Other peptoids are designed so as to have greater or lesser activity than known proteins and may be designed so as to block known receptor sites and/or elicit a desired immunogenic response and thereby act as vaccines. A range of different amino acid substitutes are disclosed, as are their methods of synthesis and methods of using such amino acid substitutes in the synthesis of peptoids and peptoid libraries. Methods of screening the libraries in order to obtain desired peptoids of a particular biological activity are also disclosed.
