摘要： A method for treating a substrate having a layer or coating of material thereon (such as for example a metal conductor coated with an insulating ‘enamel’) comprises the steps of directing a pulsed beam of laser radiation at the substrate to cause an interaction or adjacent the interface between the layer or coating and the substrate, leading to local separation of the layer or coating. The removal is effected by creating an interaction effect at the interface between the substrate and the layer or coating to create an effect similar to a shockwave which causes local separation of the layer or coating at the interface.

摘要： The invention provides new compositions which change color on exposure to actinic radiation and contain a photosensitive onium, e.g. iodonium or sulphonium, salt and a dyestuff which changes color when protonated. The compositions may also include a resin, especially a resin curable by the onium salt when the latter is exposed, and preferably an epoxy resin. The compositions are useful especially as coatings, e.g. for making screen stencils or for producing lithographic printing plates.

摘要： A server computer generates an update file for transmission to a client computer that permits the client computer to generate a copy of a current version of a subscription file from a copy of an earlier version of the subscription file. For each segment of the current version of the subscription file, the server computer searches an earlier version of a signature list for an old segment signature which matches a new segment signature corresponding to the segment. When a match is detected, the server computer writes a command in the update file for the client computer to copy an old segment of the client computer's copy of the earlier version of the subscription file into the client computer's copy of the current version of the subscription file, where the old segment corresponds to the segment for which a match was detected. When no match is detected, the server computer writes a command into the update file for the client computer to insert a new segment of the current version of the subscription file into the client computer's copy of the current version of the subscription file, where the new segment of the current version of the subscription file is written into the update file. The new segment of the current version of the subscription file may be compressed, encrypted, or both, by the server computer. When the update file is completed, the server computer transmits the update file to the client computer as an executable attachment via electronic mail. The update file is only generated when the server computer determines the subscription file has changed. The server computer periodically monitors the subscription file to determine if it has been altered before generating an update file.
摘要翻译：服务器计算机生成用于传输到客户端计算机的更新文件，其允许客户端计算机从预订文件的早期版本的副本生成订阅文件的当前版本的副本。对于订阅文件的当前版本的每个段，服务器计算机搜索签名列表的较早版本，用于与对应于该段的新段签名相匹配的旧段签名。当检测到匹配时，服务器计算机将命令写入客户端计算机的更新文件中，以将客户端计算机的早期版本的订阅文件的副本复制到客户端计算机的订阅当前版本的副本中文件，旧段对应于检测到匹配的段。当检测不到匹配时，服务器计算机将命令写入客户端计算机的更新文件，以将当前版本的订阅文件的新段插入客户端计算机的订阅文件的当前版本的副本，其中新的订阅文件的当前版本的段被写入更新文件。订阅文件的当前版本的新的段可以被服务器计算机压缩，加密或两者。当更新文件完成时，服务器计算机通过电子邮件将更新文件作为可执行附件发送到客户端计算机。更新文件仅在服务器计算机确定订阅文件已更改时生成。服务器计算机定期监视订阅文件，以确定在生成更新文件之前是否已更改。

Compositions of the invention show high light sensitivity with low levels of photocrosslinkable groups grafted to the polyvinyl alcohol.

摘要： A server computer updates client computers' copies of subscription files stored on a network. The server computer retrieves a database record from a subscription database. The database record includes at least client computer and subscription file information. The server computer checks the subscription file stored on the network for any changes which may have occurred to the file since the previous checking of the subscription file preferably by comparing the last save time stamp to a time stamp on the subscription file stored on the network. If changes have occurred, the server computer creates an update file for the client computer and transmits the update file to the client computer, preferably by electronic mail. Each database record may further contain a check interval indicating the periodicity of the checking of the subscription file for changes. The database record may further contain a time last checked field which is updated each time the subscription file is checked for changes. The subscription file is checked for changes only when the current time is equal to or greater than the time last checked plus the check interval. The subscription database is built by the server computer. The server computer receives subscription information from each client computer which includes at least the client computer and subscription file information, and this information is stored. The subscription database is stored either on the server computer's hard disk or on the network.
摘要翻译：服务器计算机更新存储在网络上的订阅文件的客户端计算机副本。服务器计算机从订阅数据库检索数据库记录。数据库记录至少包括客户端计算机和订阅文件信息。服务器计算机检查存储在网络上的订阅文件，因为自上次检查订阅文件以来可能对文件发生的任何改变，优选地通过将上一个保存时间戳与存储在网络上的订阅文件上的时间戳进行比较。如果发生更改，则服务器计算机为客户端计算机创建一个更新文件，最好通过电子邮件将更新文件发送到客户端计算机。每个数据库记录还可以包含检查间隔，其指示用于更改的订阅文件的检查周期。数据库记录还可以包含最后检查的时间字段，每当检查订阅文件的变化时，该字段将被更新。仅当当前时间等于或大于上次检查的时间加上检查间隔时，才会检查订阅文件的更改。订阅数据库由服务器计算机构建。服务器计算机从每个客户端计算机接收至少包括客户端计算机和订阅文件信息的订阅信息，并存储该信息。订阅数据库存储在服务器计算机的硬盘或网络上。
