Abstract: User interface systems and methods for roof estimation are described. Example embodiments include a roof estimation system that provides a user interface configured to facilitate roof model generation based on one or more aerial images of a building roof. In one embodiment, roof model generation includes image registration, image lean correction, roof section pitch determination, wire frame model construction, and/or roof model review. The described user interface provides user interface controls that may be manipulated by an operator to perform at least some of the functions of roof model generation. The user interface is further configured to concurrently display roof features onto multiple images of a roof. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A method and apparatus for the production of ketones via a one-step synthesis from aldehydes. In the method of the invention, an aldehyde, a carboxylic acid, and a source of oxygen, such as water, are allowed to react in the vapor phase in a catalytic tube reactor. Asymmetrical ketones, such as methyl cyclopropyl ketone, are particularly desirable reaction products.

Abstract: A method and apparatus for continuously producing a ketone in a tube reactor at elevated weight hourly space velocities and in the presence of a catalyst from feed material comprised of a first carboxylic acid or aldehyde or their derivatives and a second carboxylic acid and a method for using the ketone production method to produce herbicidal or other agricultural compounds.

Abstract: A process for the preparation of a compound of formula (I) wherein: R1 is cycloalkyl having from three to six ring carbon atoms which is unsubstituted or which has one or more substituents selected from the group consisting of R4 and halogen.

Abstract: A method and an apparatus for producing aromatic aldehydes, including benzaldehyde and metatolualdehyde wherein the reaction occurs in the vapor phase. Raw materials and a source of oxygen are fed into a tube reactor. The raw materials may be in a liquid or vapor phase. The reaction to form the aldehyde is catalyzed by suitable solid or liquid catalysts, including copper containing catalysts.
