An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient's skin and supports a retainer. The retainer releasably receives a portion of the catheter and includes one or more retention mechanisms. The retention mechanisms inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. In one mode, the retention mechanism is positioned within a channel of the retainer and includes at least first and second members that project from opposite sides of the channel. The members are arranged to cooperate with one another when the cover is closed so as to capture a structural portion of the catheter between the first and second members without substantially occluding an inner lumen of the catheter.

An intumescent fire protection barrier in the form of an adhesive sheet or continuous roll of tape. The barrier comprises laminated layers of an intumescent material, a reinforcing matrix, a pressure sensitive adhesive and a release liner. The intumescent material is adhesively applied to a structural steel substrate and expands by at least 10 times its original thickness during a fire to provide fire protection to the substrate. Multiple layers of the fire protection barrier may be installed on top of one another. This application method dramatically reduces installation time as compared with sprayed on fire protection coatings.

The invention further provides shaped bodies comprising a substrate having a durable, firmly adhering release layer and also processes for producing them. The shaped bodies of the invention are suitable for use in the field of corrosive nonferrous metal melts.

A policy application method for Machine Type Communication (MTC) and a Policy and Charging Enforcement Function (PCEF) are provided by the disclosure. The method comprises that in a course in which an MTC device attached to a PCEF establishes an Internet Protocol-Connectivity Access Network (IP-CAN) session, the PCEF locally obtains a group policy corresponding to a device group to which the MTC device belongs (S302); the group policy is applied in the IP-CAN session (S304). The technical solution of the disclosure reduces the time required by applying the MTC policy by the PCEF, saves network resources, and increases utilization of the network resources.

A soft robotic actuator is disclosed. The actuator includes a first portion with a substantially constant profile and a second portion with a regularly varying profile, and bends in a pressure-dependent fashion as the internal pressure within the actuator is increased or decreased. The present invention addresses the needs described above by providing actuators that are configured to perform new fundamental motions through the inclusion of design elements which can be configured, through the manipulation of a relatively short list of parameters, to undergo specific pressure-actuated changes which can be designed using quantitative modeling techniques.

The invention discloses a quickly dried alcohol based spraying casting coating and a spraying method thereof. The quickly dried alcohol based spraying casting coating comprises the following components in parts by weight: 60-65 parts of fire resistant powder material, 3-4 parts of suspension agent, 15-20 parts of low boiling point solvent, 15-20 parts of medium boiling point solvent, 1-2 parts of bonding agent and 1 part of assistant. The quickly dried alcohol based spraying casting coating can fully meet the spraying usage requirement; according to different castings, different fire resistant materials are used so as to meet the production requirements of different castings.

The invention relates to a DTPA modified material and a preparation method for a rapid-full-dissociation type DGT (Diffusive gradients in thin films) coupling phase prepared therefrom. DTPA reacts with Mg<2+> and Al<3+> under alkaline conditions. The method comprises the steps: (1) adding 24.4ml of ammonia water (NH4(OH)) and methanol into 73.20ml of water, uniformly mixing the ammonia water, the methanol and the water, then, adding 32.78g of DTPA into the mixture, and thoroughly dissolving DTPA; (2) fetching another beaker, adding 593.34ml of water and 197.78ml of ammonia water into the beaker, uniformly mixing the water and the ammonia water thoroughly; and (3) simultaneously adding solutions obtained in the step (1) and the step (2) into a solution containing MgCl2.6H2O and AlCl3.6H2O so as to prepare the DTPA modified material, carrying out spray drying, then, sieving the dried DTPA modified material by a sieve with the pore size of 200 meshes (75 microns) so as to form a heavy-metal adsorption material for a DGT coupled film, then, adding the heavy-metal adsorption material into a polyacrylamide gel solution, and carrying out reaction at a certain temperature, thereby preparing the DGT coupled film. The gel film prepared by the method disclosed by the invention has the effects of heavy-metal adsorption and short-time full dissociation, and the disadvantage that the dissociation of the former heavy-metal coupling phase is slow and incomplete is overcome. The materials used are cheap and are easily prepared, and no secondary pollution is caused, so that the popularization and application of a DGT technology are facilitated.

The invention discloses a method for preparing a water-based fracturing fluid by using a multi-effect thickener, which is characterized in that the fracturing fluid is composed of a base fluid and a cross-linking fluid containing a gel breaker, and is mixed according to the following parts by weight Uniform: 60-99.99 parts of base liquid, 0.01-40.0 parts of cross-linking liquid containing gel breaker; the base liquid is mixed according to the following parts by weight: 99-99.9 parts of water, multi-effect Thickener is 0.1-1.0 parts; the cross-linking liquid containing breaker is mixed according to the following parts by weight: water is 0-99.9 parts, cross-linking agent is 0.1-100.0 parts and breaker is 0.001- 0.1 part. The water-based fracturing fluid formulated with this multi-effect thickener can meet the requirements of use without adding bactericides, clay stabilizers, surfactants, demulsifiers, and foaming agents. Under the condition that the performance indicators of the fracturing fluid are equivalent to those of the traditional fracturing fluid, the operation process is simplified, which is more conducive to improving the quality of the fluid, reducing the conditions required for monitoring, reducing construction procedures and time applications.

Cetyl pyridinium chloride and other amphiphilic substances may be mixed with flavorants or therapeutics in accompaniment with such as bulking agents or sweeteners in order to prolong their duration of action at the site of attachment, which is a mucin coated surface for the purpose of providing the consumer with a more efficacious product.It is the concept of delayed dispensing that is the invention, the product being dispensed is only an illustration of the best mode.

A liquid perfume diffuser includes a perfume bottle holding a liquid perfume, an inner cap threaded onto the perfume bottle, a rotary cover rotatably capped on the inner cap for pressing and rotating by the user to move the inner cap relative to the perfume bottle between a close position and an open position, so that when the perfume is opened, the liquid perfume can then be absorbed by a liquid-absorbing material in the rotary cap, enabling the pleasant smell of the liquid perfume to be slowly and naturally released into the outside open air through a capillary effect.
