• b) polymerizing the inner phase to completion by means of a free-radical initiator, the free-radical initiator being added to the outer phase (aqueous phase) in a concentration of 0.1 to 40% by weight based on the inner phase, and to the use of the particles alone or in a mixture with further particles, pigments and/or further customary additives in the form of powders or dispersions in coating, adhesive or sealant materials, in polymers, in defoamers, in wetting and levelling aids, in cosmetic or pharmaceutical formulations and care products, in cleaning and detergent compositions, or in applications for modifying the interface properties of solid and liquid substrates, for example tactile properties, hydrophobization, or sliding and/or release properties.

The invention discloses an anti-free flow mechanism for a finger-type peristaltic infusion pump (DDS) comprising: a passive mechanical interface (MS) which integrally accommodates a portion of a flexible infusion-tube, and an anti-free flow valve (AFFV) which is a spring-activated latch incorporated with the (MS). The maneuverable latch is secured in the (MS) either in a closed or opened configuration: in its closed configuration no flow is provided and in its opened configuration, a free flow is facilitated. The anti-free flow is configured in a manner that when the (MS) is not properly mounted in the (DDS), the (AFFV) is automatically actuated to its closed configuration, and vice versa that when the (MS) is properly mounted in the (DDS), the latch is adapted to be automatically switched to the opened configuration The invention also presents methods for avoiding anti-free flow in finger-type peristaltic infusion pumps.

The present invention provides a system and methodology for dummy-dispensing resist though a dispense head while mitigating waste associated with the dummy-dispense process. The dummy dispensed resist is returned to a reservoir from which it was taken. Between substrate applications, the dispense head can be positioned to dispense resist into a return line. The flow of resist from the dispense head keeps resist from drying at the dispense head. By funneling the dummy-dispensed resist into a return line with low volume, for example, waste from the dummy-dispensing process can be mitigated.

The invention relates to a vehicle headlight cleaning apparatus. A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. Both ends of the spring are respectively fixed on the end part of the cleaning apparatus and a spring fixing seat of the movable seal valve. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. The pressure of the cleaning solution increases continuously, then the movable seal valve is opened under the pressure of the cleaning solution, the cleaning solution sprays out through the transmission guide rod and the nozzle, and a complete cleaning circuit is formed. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring, the transmission guide rod retracts into the casing till to an initial position, and the whole cleaning is finished. The invention has small and exquisite appearance, light weight, reliable work and high cleaning efficient.
