Abstract: A method and apparatus for forming an optical stack having uniform and accurate layers is provided. A processing tool used to form the optical stack comprises, within an enclosed environment, a first transfer chamber, an on-board metrology unit, and a second transfer chamber. A first plurality of processing chambers is coupled to the first transfer chamber or the second transfer chamber. The on-board metrology unit is disposed between the first transfer chamber and the second transfer chamber. The on-board metrology unit is configured to measure one or more optical properties of the individual layers of the optical stack without exposing the layers to an ambient environment.

Abstract: A method of selecting a file for printing is disclosed. The method includes receiving a selection of a folder, the folder includes a plurality of files and at least one file to be printed. A pre-defined option is displayed to select the at least one file for printing based on a choice of the user. Upon selection, one or more choice options are displayed. The user provides one or more choice inputs corresponding to the choice options. Then, the choice inputs provided by the user are received. One or more files are automatically identified and automatically selected based on the choice inputs by searching in the plurality of files. The one or more automatically selected files along with other non-selected files present in the folder are displayed. The user is prompted to confirm the automatically selected files for printing. Upon confirmation, the automatically selected files are sent for printing.

Abstract: The disclosure discloses methods and systems for intelligent copying of bound documents. The method includes receiving a selection of copying a bound document via a user interface. The user interface is presented to the user to input whether a starting page of the bound document for copying is a left-side page or a right-side page. Then, multiple pages of the bound document are scanned to generate corresponding scanned images. Finally, the generated scanned images are arranged in the same order as per the arrangement of pages in the original bound document.

Abstract: An engine is disclosed. The engine includes a cylinder block having a bore and a cylinder head. The engine includes a spacer plate disposed between the cylinder block and the cylinder head. The spacer plate includes an aperture having a first taper portion. The engine also includes a cylinder liner having a fourth surface and received in the bore of the cylinder block. The fourth surface includes a second portion. The fourth surface also includes a second taper portion extending from the second portion and inclined at an angle with respect to the second portion. The second portion and the second taper portion define a fillet. The fourth surface includes a third portion extending from the second taper portion. The third portion defines a differential angle with respect to the second taper portion. The fourth surface also includes a sealing portion abutting the first taper portion of the spacer plate.

Abstract: The present invention relates to an improved process for the preparation of cefprozil DMF solvate of formula (I), which is useful for the preparation of cefprozil, comprising: i) reacting a compound of formula (VIII) with acetaldehyde to produce a compound of formula (IX), ii) deesterifying the carboxy protecting group of the compound of formula (IX) using an acid to yield a compound of formula (X), iii) converting the compound of formula (X) to a compound of formula (XI), iv) neutralizing the compound of formula (XI) followed by enzymatic hydrolysis to produce an APCA of formula (V), v) silylating the APCA using a mixture of trimethylsilylchloride and hexamethyldisilazane to produce silylated APCA of formula (XII), and vi) condensing the silylated APCA with a mixed anhydride to produce the DMF solvate compound of formula (I).

Abstract: The present invention relates to an improved process for the preparation of 3-propenyl cephalosporin DMF solvate, more particularly, the present invention relates to an improved process for the preparation of cefprozil DMF solvate of the formula (I), which is useful for the preparation of cefprozil of the formula (XIV).
