摘要:
The spread of printing paste when applied to textiles is inhibited by the inclusion of an "anti-wick agent" in the print paste. The "anti-wick agent" comprises a copolymer resulting from the polymerization of at least one monomer selected from the group consisting of methacrylic acid, acrylic acid, maleic acid and maleic anhydride with at least one monomer selected from the group consisting of acrylate esters and N-substituted acrylamides.
摘要:
A mixture in-oil antifoam composition comprising a mixture of a defoaming agent comprising a defoamer in an oil carrier, a non-ionic surfactant having an HLB number less than about 10, and water. In particular, the defoamer is particulate hydrophobic silica dispersed in oil and the non-ionic surfactant has an HLB number of between 2 to 8.

The present invention relates to a process using ultrasonic cutting for the preparation of an oral delivery device comprising a core which includes a pharmaceutically active agent covered by an outer coating which includes one or more openings communicating from the exterior of the device toward the core.

An apparatus, method, and machine-readable medium are described for establishing peer-to-peer (“P2P”) communication channels. In particular, in one embodiment, a matchmaker service performs a series of operations to service match requests received from a group of mobile devices. In one embodiment, the matchmaker service groups the match requests into matchable sets based on the application for which the requests are received and one or more variables associated with the application. Match requests within each match set can then be matched based on variables such as the NAT type, connection type and language associated with each of the mobile devices. Other variables such as geographical location, experience level, and age of the match requests may also be used to render match decisions.
摘要:
Perfluoropolymer made without ionic species, initiator and without halocarbon solvent polymerization medium and dispersing agent is beneficially useful in liquid contact or food contact applications, for high-speed melt extrusion wire coating, and to produce insulated wire exhibiting low dissipation factor at high signal frequencies.
摘要:
Simultaneous transmission of voice and data over the voice channel of a digital wireless communications network, such as a “cell phone” network, is reconfigurable on the fly among multiple operating modes, including a lull detection mode in which data is transferred during a lull or quiet period in the voice content. Additionally, control signaling in the voice channel, rather than over a separate control or “overhead” channel is employed to support SVD. The described system operates transparently over any wireless telecommunications system.

A control apparatus is disclosed for controlling nip pressure in a nip of a metering size press. The apparatus includes a metering size press roll and a backing roll which cooperates with the size press roll for defining therebetween the nip. A support post is provided for rotatably supporting the backing roll. A linear bearing is disposed beneath the support post for mounting the support post. Also, a moving device is connected to the support post for moving the support post and the backing roll supported by the support post such that the supported backing roll and the support post mounted on the linear bearing is moved for controlling the nip pressure in the nip between the rolls.
摘要:
A combination crutch and knee walker device converts between a rolling knee walker configuration and a crutch configuration through a single folding or expanding articulation that requires no tools or skillset. The device includes a first support bar that forms the primary lever of support. A second support bar pivotally joins the first support bar at a hinged junction, generally three-quarters down from the top of the first support bar. The support bars fold and expand about the hinged junction to convert between crutch and knee walker. A panel hingedly joins at the hinged junction serving as a supportive platform for an upper body, such as the arm or the knee, depending on the crutch or knee walker configuration. Further, the mobility function, such as rolling rollers, will restrict or free rotation depending on the selected configuration of the device.
摘要:
A platform and launch initiation control system for secondary spacecraft for a launch vehicle includes an aluminum honeycomb core sandwiched between top and bottom structural aluminum skins and strengthened by a spider-like stiffener. Spool inserts for engaging the secondary spacecraft are arranged on the platform. A computer processor based auxiliary payload support unit (APSU) is provided on the platform and receives power and enable signals through a single cable from the LV to permit the APSU to control the release of the secondary spacecraft transparently to the LV without impacting LV operations.
