The clear coating is particularly useful as an automotive OEM clear coating or as a refinish clear coating. The coating has two components. Component A of the coating composition includes a melamine and an acrylosilane polymer of a polymerized monomers mixture, which includes an alkyl methacrylate, an alkyl acrylate, cycloaliphatic alkyl methacrylate, cycloaliphatic alkyl acrylate, styrene or any mixture of these monomers; hydroxy alkyl methacrylate, hydroxy alkyl acrylate or any mixtures of these monomers; and a mono-ethylenically unsaturated silane monomer. Component B of the composition includes an organic polyisocyanate as a crosslinking agent.

US Classification:

4353201, 435325

Abstract:

The present invention relates to a method of isolating stem cells from a mixed population of different cell types. This method involves selecting a promoter which functions only in said stem cells and not in the other cell types. The promoter can have a nucleotide sequence selected from the group consisting of SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, and SEQ ID NO: 8. A nucleic acid molecule encoding a marker protein under control of said promoter is introduced into all cell types of said mixed population and only the stem cells, but not the other cell types, within said mixed population are allowed to express said marker protein. The cells of said mixed population of cell types that are expressing the marker protein, which are restricted to the stem cells are identified and separated from the mixed population, where the separated cells are restricted to the stem cells. The promoter, nucleic acid constructs comprising it, and the resulting stem cells are also disclosed. The nucleic constructs can be incorporated in transgenic animals in order to monitor stem cell movement.

International Classification:

B05D 1/36

US Classification:

4274071, 524547

Abstract:

A curable film-forming coating composition, typically a clearcoat, having improved compatibility over waterborne and solventborne basecoats. The composition includes a film-forming binder comprising a carbamate material, a curing agent, typically a monomeric melamine curing agent, and a hydroxy functional silane component. When used as a clearcoat over a standard pigmented basecoat, the resulting coating provides a substantially wrinkle free appearance and excellent adhesion to both waterborne and solventborne basecoats.

US Classification:

427258, 427261, 427282

Abstract:

A method for producing a multilayer two-tone finish on a substrate such as an automobile or truck body or parts thereof. The method includes the steps of applying two different primers to a substrate, applying an accent color to a portion of the substrate and baking the applied coatings. The accent area is then masked and a main color is applied to the unmasked portion of the substrate. The mask is then removed from the accent color area, a clearcoat is applied to the applied main and accent colors and the substrate is baked to dry and cure the applied coating compositions. The clearcoat composition carbamate material, a curing agent and a hydroxy functional silane component. The method and the clearcoat composition provides a substantially durable and wrinkle free appearance and excellent adhesion to waterborne and solventborne basecoats, baked or unbaked.

International Classification:

H04W 4/00

US Classification:

4554351

Abstract:

Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A first SIM may perform a data transfer or voice call. During the first SIM's data transfer or voice call, transition times are identified to transition communication resources to a second SIM for use in performing a registration update communication with a network controller that supports the second SIM. The registration update communication may include a periodic location update, a periodic routing update, or a periodic tracking update. The multiple SIM device may identify the transition time by obtaining periodic registration timing information from the network controller, configuring a periodic registration timer based on the periodic registration timing information, and setting the transition time as an expiration time of the periodic registration timer.
