Abstract: A  front  shield  extends  across  an  end  portion  of  a reciprocating floor conveyor above the conveyor slats.  Each slat has a front end that reciprocates longitudinally between first  and second positions  as  the slat reciprocates.   A multiplicity of bristles are carried by the shield and depend downwardly therefrom.  The lower ends of the bristles contact a top surface of the slats rearwardly of the first and second positions.   The bristles are bent by contact with the top surface to preload them into contact and maintain them in contact as the slats reciprocate.  This prevents particles of material and debris  from passing under  the shield.   The bristles are mounted on the shield by means of a carrier that is vertically adjustable relative to the shield to permit adjustment of the preload.   The bristles are provided in a plurality  of  rows  positioned  one  behind  another  in  a longitudinal direction, with each row extending across the conveyor substantially continuously across each slat.   The bristles have a sufficiently narrow cross section and are sufficiently close to each other to provide a substantially constant seal across contoured slats.

Abstract: An article having a durable non-wetting surface is disclosed wherein a plastic substrate surface is first treated by deposition of a silica primer layer.  The plastic substrate surface bearing the silica primer layer is then treated with a composition comprising a perfluoroalkylalkylsilane and, optionally, a fluorinated olefin-telomer.  The perfluoroalkylalkylsilane provides the non-wetting surface property, while the silica primer layer provides durability to the non-wetting surface property.  A method of producing a durable non-wetting surface on a plastic surface is also disclosed, comprising depositing a silica primer layer on a surface of the plastic substrate, and then contacting the silica primer layer with a perfluoroalkylalkylsilane composition.  The silica primer layer is preferably deposited by applying to the plastic substrate surface a solution of a hydrolyzable silicon-containing compound, such as tetrachlorosilane, which hydrolyzes and condenses to form a silica-containing film.

Granted: 2006-05-16
Abstract: The particle collection efficiency of a fibrous filter (11) is signifi-cantly increased by imposing a high voltage potential on electrodes (15, 16) placed on either side of the filter (17). This creates a strong elec-trostatic field across the filter (17) which enhances the fiber's particle collection ability. The electrostatic field strength, and particle collection efficiency, increase with the voltage employed to establish the electrostatic field. An insulated electrode (15) as the front electrode (15) in combina-tion with a conductive electrode (16) as the rear electrode (16) enables a very high electrical potential to be imposed on the electrodes (15, 16) without resulting arcing between the electrodes (15, 16). Pre-charging of dust particulates with the same polarity as the insulated electrode fur-ther increases collection efficiency without resulting in a charge buildup in front of the electrodes (15, 16) or a blocking of airflow by particles collecting on the electrodes (15, 16).

Abstract: Cette invention concerne un procédé permettant de récupérer les monomères n'ayant pas réagi et de rejeter le sous-produit d'un réacteur de polymérisation au cours d'un processus de polymérisation d'oléfines, le(s) flux de gaz perdus du réacteur, qui contiennent des monomères n'ayant pas réagi, un sous-produit de réacteur et des composants légers, étant traité(s) au moyen d'un procédé d'absorption permettant en outre de récupérer les monomères. Ce procédé d'absorption consiste à mettre le(s) flux de gaz perdus en contact avec un solvant d'absorption dans une zone d'absorption de façon à créer un flux de gaz contenant les composants légers et un flux de liquide contenant le solvant d'absorption, le sous-produit de réacteur absorbé et les monomères absorbés. On fractionne le flux liquide dans une colonne de distillation pour obtenir un flux de fond de colonne de distillation constitué du solvant d'absorption qui est transporté vers la zone d'absorption, et un flux de distillat de tête contenant les monomères et le sous-produit de réacteur qui subit un fractionnement supplémentaire dans une colonne de fractionnement aux fins du rejet du sous-produit de réacteur sous forme de flux de fond. Les monomères récupérés dans le distillat de tête de la colonne de fractionnement peuvent être acheminés vers le réacteur. Selon un mode de réalisation préféré, on utilise comme solvant d'absorption un mélange constitué essentiellement de composants dérivés du(des) flux de gaz perdus si bien qu'aucun solvant externe n'est nécessaire.

Abstract: A distributed processing system (100) includes a protocol server (101) that enables a plurality of clients (103-104) to share the use of one set of Signaling System 7 (SS7) links (99), that centralizes the link-termination circuitry (110) for use by the plurality of clients, and that provides access to upper layers (215-219) of the SS7 protocol stack (200) by distributing the processing of different layers of the stack between the protocol server and the clients. The protocol server terminates the lower layers (210-213) of the SS7 protocol, while each client terminates the upper layers of the SS7 protocol. Communication between the protocol server and the clients of information expressed in the upper layers of the SS7 protocol is effected via the TCP/IP protocol over a LAN (102). A service access bridge process (113, 116) in the protocol server translates between the lower layers of the SS7 protocol and the TCP/IP protocol, and a distributed signaling server process (114, 117) in the protocol server routes communications across the LAN. A distributed signaling client process (121, 124) in each client translates between the TCP/IP protocol and the upper layers of the SS7 protocol. The distributed signaling server and distributed signaling client processes are substantially protocol independent, allowing for use of any protocol in place of the SS7 protocol. The distributed processing system may be either a multiprocessor or a uniprocessor.
