Abstract: The invention provides an improved process to manufacture 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) by reacting 2-chloro-3,3,3,-trifluoropropene (HCFO-1233xf) with hydrogen fluoride, in the presence of a fluorination catalyst, where by using 2-chloro-3,3,3,-trifluoropropene (HCFO-1233xf) of high purity, the need to add an oxidizing agent (typically chlorine) to keep the catalyst active can be avoided. The HCFC-244bb is then used as an intermediate in the production of 2,3,3,3-tetrafluoropropene-1 (HFO-1234yf).

Abstract: The invention provides an improved process to manufacture 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) by reacting 2-chloro-3,3,3,-trifluoropropene (HCFO-1233xf) with hydrogen fluoride, in a liquid phase reaction in the presence of hydrogen chloride and a liquid phase fluorination catalyst. The hydrogen chloride is added into the reaction from an external source at a pressure of about 100 psig or more. The HCFC-244bb is an intermediate in the production of 2,3,3,3-tetrafluoropropene-1 (HFO-1234yf).

Abstract: A data object management scheme for storing a large plurality of small data objects (e.g., image files) in small number of large object stack file for storage in secondary storage (e.g., hard disks). By storing many individual data objects in a single object stack file, the number of files stored in the secondary storage is reduced by several orders of magnitude, from the billions or millions to the hundreds or so. Index data for each object stack file is generated and stored in primary storage to allow efficient and prompt access to the data objects. Requests to store or retrieve the data objects are made using HTTP messages including file identifiers that identify the files storing the data objects and keys identifying the data objects. A file server stores or retrieves the data object from secondary storage of a file server without converting the requests to NSF or POSIX commands.

Abstract: Compositions and methods based on the use of fluoroalkene containing from 3 to 4 carbon atoms and at least one carbon-carbon double bond, such as HFO-1214, HFO-HFO-1233, or HFO-1354, having properties highly beneficial in foaming and blowing agent applications, articles and methods.

Abstract: A system, method and program product for creating a UML model of a user interface environment, such as a website. A UML design system is disclosed that includes: a system for defining use cases within the UML model; a system for associating an affinity representing a user-perceived relationship between use cases within the UML model; and a system for assigning a weight to the affinity within the UML model.

Abstract: Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF?CH2 (1234yf). In certain preferred embodiments the processes comprise first exposing a compound of Formula (IA) C(X)2?CClC(X)3??(IA) where each X is independently F, Cl or H, preferably CCl2?CClCH2Cl, to one or more sets of reaction conditions, but preferably a substantially single set of reaction conditions, effective to produce at least one chlorofluoropropane, preferably in accordance with Formula (IB): CF3CClX?C(X?)3??Formula (IB) where each X? is independently F, Cl or H, and then exposing the compound of Formula (IB) to one or more sets of reaction conditions, but preferably a substantially single set of reaction conditions, effective to produce a compound of Formula (II) CF3CF?CHZ??(II) where Z is H, F, Cl, I or Br.

Abstract: A click pen applicator device that provides predetermined dosing of the formulation for precise application, and rapidly primes the formulation using the dosing click mechanism to prepare the applicator for use is disclosed.

Abstract: Controlling information resources involves accessing a control definition of a number of control definitions associated with a first party and a second party. The first party has a first information resource and the second party has a second information resource, where the first information resource is in communication with the second information resource. The control definitions define a practice for monitoring the second information resource, where each control definition has a condition and a consequence. Meta-data is received from a second monitor of the second information resource, where the meta-data describes operation of the second information resource. The condition is applied to the meta-data in order to monitor the second information resource.

Abstract: A transducer assembly for connecting a transducer to a device, the transducer assembly having a transducer mount adapted to receive the transducer, and a clamp having first and second jaws, the first and second jaws being adapted to selectively clamp to a flange portion of the device. The transducer mount may include a housing, a resilient member, and first and second end walls. The first end wall may be operatively connected to the device. The transducer may be held within the housing and adjacent to the first end wall. The resilient member may be disposed between the transducer and the second end wall.
