A casing for a writing instrument comprises an outer shaft, an inner shaft, and a nib. The outer shaft is formed using dual injection molding. An outer surface of the outer shaft includes a raised hard part and a raised soft part. The inner shaft is formed of a thin-wall tube having an upper end and a lower end, the inner shaft being configured for insertion inside the outer shaft. The inner shaft further includes a fastener protruding on its upper end that engages an upper end of the outer shaft. The nib is configured to engage the lower end of the inner shaft to help secure the inner shaft within the outer shaft. The raised hard or soft parts on the outer surface of the outer shaft may include an oblique loop-shaped part, a strip-shaped part, and/or an arc-shaped part.

A novel method of preparation of easily stripped off temporary wound dressing material is disclosed. In this process, the-N-isopropyl acrylamide (NIPAAm) monomer is successfully grafted on the non-woven cloths by copolymerization. It is initiated by .gamma.-ray irradiation to activate the surface of the non-woven cloth. NIPAAm is then grafted onto the surface of the non-woven cloth. The free radical or peroxide is produced by Co-60 .gamma.-ray, then grafted on the non-woven cloths. The lower critical solution temperature (LCST) in thermoresponsive poly-N-isopropylacrylamide (NIPAAm) is still retained after the grafting. This will make the dressing cloth stripped off easily and without hurting the tissue. The material process is very simple and has medically applicable value.

A liquid surfactant composition can include a C9-C20 alkylbenzene sulfonate, a first alcohol ether sulfate (AES), and a nonionic surfactant. The first AES surfactant can have a molecular formula of R1—O—(CH2—CH2—O)m—SO3M, wherein R1 represents a C10-C20 alkyl group, m represents a number from 6 to 8, and M represents a monovalent cation. The first AES surfactant can be a modified oxo-alcohol-based surfactant.

The present disclosure is a novel utility of a software defined radio (SDR) based Distributed Antenna System (DAS) that is field reconfigurable and support multi-modulation schemes (modulation-independent), multi-carriers, multi-frequency bands and multi-channels. More specifically, the present invention relates to a DAS utilizing one or more Daisy-Chained Rings of Remote Units. The present invention enables a high degree of flexibility to manage, control, enhance, facilitate the usage and performance of a distributed wireless network such as Flexible Simulcast, automatic traffic load-balancing, network and radio resource optimization, network calibration, autonomous/assisted commissioning, carrier pooling, automatic frequency selection, frequency carrier placement, traffic monitoring, traffic tagging, pilot beacon, etc. As a result, a DAS in accordance with the present invention can increase the efficiency and traffic capacity of the operators' wireless network.

The present invention is embodied in a grill configured for quick assembly, a method of partially pre-assembling the grill for shipping from the factory in a container, and a method of assembling the grill when removed from the shipping container. The grill comprises a firebox assembly for mounting on a cart assembly, the cart assembly having first and second support assemblies and at least one linking member interconnecting them. A hinge or pivot in the mid-portion of the linking member divides it into first and second linking member portions, and the opposite ends of the linking member portions are pivotally connected by hinges or the like to the first and second support assemblies. The linking member holds the first and second support assemblies together in a partially pre-assembled state, and the pivotal connections of the linking member portions allow the two assemblies to be folded for packaging in a shipping container. When removed from the container, the pivotal connections of the linking member portions allow the first and second support assemblies to be unfolded, with the linking member holding the two support assemblies in approximately the proper position with respect to each other and to the firebox assembly for assembly of the grill, thus allowing for easier and quicker grill assembly by one person. Alternatively, the linking member can itself be a support assembly with the first and second support assemblies pivotally attached to opposite ends of the linking member.

Methods of forming a molded composite material are generally provided. A composite forming precursor (e.g., fibers and/or a resin material) can be applied onto a mold that includes a plurality of piezoelectric sensors embedded into the mold. The composite forming precursor can then be cured adjacent to the mold to form a molded composite material. During curing, the molded composite material can be monitored, using the piezoelectric sensors to detect any defects formed during curing.

An air/water advanced oxidation purification device includes a draft tube, a motor and at least one spiral partition plate. The spiral partition plate is fixed on an output shaft of the motor. The motor is supported in the draft tube and used for driving the spiral partition plate to rotate at uniform speed around the central axis of the draft tube and for driving air or water to enter into the draft tube. The spiral partition plate includes a plurality of miniature blades arranged along a radial direction of the spiral partition plate, each of the miniature blades includes a plurality of first and second protrusions continuously and staggered arranged along the radial direction and protruding towards two sides of the spiral partition plate, respectively. Air or water is purified through photo-catalytic advanced oxidation reaction or electro-catalytic oxidation-reduction reaction taken place on the surfaces of the spiral partition plate.
