摘要:
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.

The invention discloses an innovative process to produce highly antibacterial nano-composite fabric textile containing silver metal compound. The process mainly uses high-energy D-ray radiation to modify silver type of bactericides and graft or crosslink them onto Nylon or PET fiber surface to produce excellent antibacterial textile products. The mechanism uses silver nano-compound as performance additive and through Co-60 irradiation technique reduces and firmly fastens silver particles onto Nylon or PET (Polyethylene Terephthalate) fiber material. Because the inorganic silver type bactericides actively interact with enzymes in bacteria or destroy cell walls to achieve good bactericidal effect, the radiation process does not need initiators or other additives. So the process is simple and effective. The test results prove excellent bactericidal power and potential value in household or medical textile products.

A separation system comprises (i) at least two separation units, each separation unit comprising a fluid inlet and a fluid outlet, wherein the separation units are connected in series outlet to inlet to form a line of separation units, and (ii) sensing and adjustment means, provided in-line between each separation unit, for continuously monitoring and adjusting at least one environmental property parameter of fluid flowing from one separation unit to a subsequent separation unit in the line of separation units. Uses of the separation system and a method for purification of a liquid containing a desired species, using separation units and in-line adjustment of a fluid flow or flows, are also disclosed.
摘要:
The invention discloses a laundry article used for both cleaning and conditioning fabrics comprising a water-insoluble nonwoven substrate and coated thereon into at least one zone each a detergent composition and a fabric conditioning composition. The fabric conditioning composition comprises a quaternary ammonium cationic surfactant, an alkoxylated fatty alcohol and a fatty acid.

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.
