Abstract: A system for modifying code, said system comprising a code repository for storing code and a first code editor. The first code editor is operable to identify decorator definition code which defines metadata from code stored in the code repository and which comprises a first code component comprising source code annotated by one or more decorators and a second code component comprising the decorator definition code defining the metadata. The first code editor is further operable to present variables associated with the metadata on a user interface, and modify the variables associated with the metadata in accordance with modifications input to the code editor by a user via a user interface.

Abstract: A method includes client application code which is deployed to a client device having a generic client library. The client application code has code for accessing a web service of a web application via a web application programming interface (API) and running the client application code on the client device to: communicate a web service operation call to the web API and receive a web service operation response from the web API via the interface. The generic client library has code defining a first proxy class within which is defined a generic operation method, configured such that, responsive to receipt of an operation name parameter corresponding to a web service operation performed by the web application from a function caller of the client application code, the operation method returns an operation function object providing the interface between the client application code and the web API.

Abstract: A method of generating a SQL statement for performing a database operation. The method comprises: receiving a database operation instruction relating to an operation to be performed on one or more tables of a relational database, said database operation instruction expressed as at least one function in a general-purpose computing language and in which clauses of the database operation instruction are defined in a body of the at least one function; processing the database operation instruction to identify source code associated with the body of the at least one function; generating an abstract syntax tree from the source code, and translating the abstract syntax tree into a SQL statement corresponding to the database operation instruction.

Abstract: A method of deploying an application is provided. The method includes publishing a first code package to a package registry and publishing one or more further code packages to the package registry. The first code package can include code specifying a first definition of a class and at least one of the one or more further code packages comprises code specifying a further definition of the class. The further definition of the class comprises prototype merging so that on compilation the first definition of the class and the extended definition of the class are loaded as a single class, and module augmentation so that the first and extended definitions of the class are treated as a single merged class by development tools.

Abstract: A method of accessing a web service of a web application via a web API. The method comprises: deploying, to a client device, client application code comprising a generic client library, said client application code comprising code for accessing the web service of the web application via the web API and running the client application code on the client device to: communicate a web service operation call to the web API, running on a server device, via an interface, and receive a web service operation response from the web API via the interface.

Abstract: A multilayer composite material, suitable for capping plastic milk bottles and other containers, comprising;(a) a metal foil,(b) a polyolefin film, and(c) an adhesive layer bonding the metal foil and the polyolefin film together and formed of two compounds A and B; wherein said metal foil has a thickness between 25 and 75 microns; said polyolefin film has a thickness between 10 and 30 microns; and said adhesive layer has a thickness between 0.5 and 6 microns, and preferably between 2 and 5 microns.

Abstract: The invention relates to a two-layer composite material comprising a metal foil and an adhesive layer.The adhesive layer is formed of a mixture of two compounds A and B, compound A being a copolymer of an aliphatic monoolefin and a monoethylenically unsaturated carboxylic acid which has good adhesion for the metal foil and the container, and compound B being a compound adapted to reduce the adhesion of compound A for the metal foil and/or the container.Said composite material is intended in particular for the fabrication of caps serving as closures for containers.

Abstract: The invention relates to a process for the preparation of suspensions of at least one polymer, said process comprising as a first step the preparation of a first suspension of at least one polymer in an organic liquid by chilling a solution of said polymer.In accordance with the invention, there is added to the first polymer suspension in a second step a powder of at least one polymer, which may be the same as or different from the first.Use of said process in the production of two-layer composites formed of an aluminum sheet and a polymer layer.

Abstract: Process for, and composites made by, coating a polymer layer onto a support, obtained by quenching a solution of the polymer to form a polymer suspension, by spreading the suspension on the support, and thereafter eliminating the solvent. The resulting coating of polymer preferably may thereafter be fused. Application of said process to the production also composites comprising an aluminum film and a film thermally bonded to said support by a thin intermediate layer of a copolymer formed of acrylic acid grafted with polyethylene or polypropylene, said layer having been applied by the foregoing process.
