A disc filter is provided having a controller for controlling effluent surges that are produced by the disc filter. The method entails sensing one or more process variables that are a function of the effluent, and based at least in part on the sensed process variables, the disc filter controls the flow of effluent in order to control or minimize effluent surges.
摘要:
A disc filter having a controller for controlling or minimizing effluent surges is provided. The disc filter is operative to carry out a method or process for controlling the flow of effluent produced by the disc filter. The basic method entails sensing one or more process variables that are a function of the effluent, and based at least in part on the sensed process variables, the disc filter controls the flow of the effluent by implementing various control functions such as: 1) rotating the rotary filter discs of the disc filter one revolution or less without backwashing; 2) rotating the rotary filter discs more than one revolution at a relatively slow speed without backwashing; 3) rotating the rotary filter discs for one revolution or more at a relatively slow speed while backwashing; 4) rotating the rotary filter discs at a relatively high speed with or without backwashing; and 5) rotating the filter discs one revolution or more and periodically backwashing.
摘要:
A subscriber of a telecommunication system has a plurality of associated telecommunication devices which are each contactable via a device-shared identification address. A first device can communicate with a telecommunications network. A second device can communicate with a packet-switched network and a circuit-switched network. A control system receives an incoming telecommunication request associated with an incoming telecommunication request directed to the address, which has been routed to the control system based on the address. A first control phase is initiated where a first outgoing telecommunication request is transmitted over the telecommunications network to the first device and an operation is performed to at least attempt to transmit a second outgoing telecommunication request over the packet-switched network to the second device. If the operation is deemed to be unsuccessful, a second control phase is initiated where a third outgoing telecommunication request is transmitted over the circuit-switched network to the second device.

An extension applicator has an elongate handle (1, 19, 30) with an applicator end (3) having an attachment section (4, 48) to which an applicator attachment (5) and a mirror attachment (6) separately are attached detachably. An applicator base (7) is attached to the applicator attachment. A mirror base (8) is attached to the mirror attachment. The applicator base is structured for attachment of one of a class of attachable applicators (9). The mirror base is structured for attachment of a class of mirrors (10). The elongate handle can have a fixed shape or an adjustable shape. The attachment section is structured to receive either or both the applicator attachment and the mirror attachment.

Disclosed are copolymers derived from ethylene and at least two different alkyl acrylate comonomers, with or without an acid cure site-containing comonomer. The copolymers can be derived from (a) from 10 to 50 weight % of ethylene; (b) 20 to 30 weight % of a first alkyl acrylate having from 1 to 4 carbons in the alkyl group; from 35 to 45 weight % of a second different alkyl acrylate having from 1 to 4 carbons in the alkyl group; and (d) from 0 to 5 weight % of a 1,4-butene-dioic acid moiety, or anhydride or monoalkyl ester thereof; the remainder being ethylene: wherein the copolymer has a number average molecular weight (Mn) above 40,000. Also disclosed are compounded compositions comprising these copolymers and cured compositions (i.e., vulcanizates) as well as rubber articles formed from these compounded compositions, such as constant velocity joint boots and shaft boots, hoses, dampers, seals and gaskets. These copolymers provide improved dynamic fatigue resistance of cured compounds while maintaining an expanded operating temperature range and oil resistance. Blends of other polymers with these copolymers are also disclosed.

摘要:
Disclosed are oxygen-scavenging polymer compositions having high transparency and low haze comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, a copolyamide or a transamidized, homogeneous blend of a least two polyamides, and a metal catalyst. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.
摘要:
Steerable electrophysiology catheters for use in mapping and/or ablation of accessory pathways in myocardial tissue of the heart wall and methods of use thereof are disclosed. The catheter comprises a catheter body and handle, the catheter body having a proximal section and a distal section and manipulators that enable the deflection of a distal segment of the distal tip section with respect to the independently formed curvature of a proximal segment of the distal tip section through a bending or knuckle motion of an intermediate segment between the proximal and distal segments. A wide angular range of deflection within a very small curve or bend radius in the intermediate segment is obtained. At least one distal tip electrode is preferably confined to the distal segment which can have a straight axis extending distally from the intermediate segment. The curvature of the proximal segment and the bending angle of the intermediate segment are independently selectable. The axial alignment of the distal segment with respect to the nominal axis of the proximal shaft section of the catheter body can be varied between substantially axially aligned (0° curvature) in an abrupt knuckle bend through a range of about −90° to about +180° within a bending radius of between about 2.0 mm and 7.0 mm and preferably less than 5.0 mm. The proximal segment curve can be independently formed in a range of about −180° through about +270° with respect to the axis of the proximal shaft section to provide an optimum angular orientation of the distal electrode(s). The distal segment can comprise a highly flexible elongated distal segment body and electrode(s) that conform with the shape and curvature of the heart wall.
