摘要:
An apparatus for printing labels can have a printing area, a deflector area designed as a shaft or an edge located behind the printing area in the transport direction of the labels, around which deflector the carrier strip can be guided, and where the labels, on account of their stiffness, can be detached from the carrier strip, while the adhesive glue remains on the underside of the label. In addition, the printing apparatus can also have a supporting apparatus with a contact area near the output opening for the labels, against which supporting area the labels, output via the output opening, come into contact with their underside. The contact area of the support apparatus can preferably be formed by the exposed surfaces of balls mounted so that they can rotate in at least one retaining strip, so that during the label output, the labels preferably do not stick to the support apparatus, as such sticking would significantly interfere with the output of the labels.

The invention relates to a novel process for the manufacture of (3R,1'R)-4-acyloxy-3-(1'-hydroxyethyl)-2-azetidinones of formula ##STR1## in which R.sup.1 represents lower alkyl or aryl, by enantioselective reduction of the carbonyl group in a suitable .alpha.-acylaminomethyl-acetoacetic acid ester, cyclisation of the resulting .alpha.-acylaminomethyl-.beta.-hydroxybutyric acid ester to a 5,6-dihydro-1,3,4H-oxazine with inversion of the carbon atom carrying the hydroxy group, equilibration to form the preferred trans-substituted dihydrooxazine, recleaving to form the configuratively uniform .alpha.-aminomethyl-.beta.-hydroxybutyric acid, ring-closure to form the .beta.-lactam and oxidative acylation at C(4) of the .beta.-lactam. Compounds of formula I can be used as starting materials for the manufacture of .beta.-lactam antibiotics. The invention relates also to novel intermediates.

An example security device is provided that includes a core and a shuttle. The core includes an internal jaw and a guide surface and a distance between the internal jaw and the guide surface varies across a length of the core. The shuttle includes an opening that forms an external jaw. A jaw gap is defined between the internal jaw and the external jaw that is configured to receive a portion of an item to protect.
摘要:
Creation of an index for a table of sorted data for use by a data storage application is initiated. Thereafter, N+1 logical partition of rows of the table are defined so that each logical partition has a corresponding worker process. Each worker process then builds a sub-index based on the corresponding logical partition which are later merged to form the index. Related apparatus, systems, techniques and articles are also described.

A method can include receiving a request to execute a database command identifying a target table; identifying a plurality of rows to insert into the target table based in part on the database command; writing rows, from the plurality of rows, into a data page until the data page is full; determining, by an index thread manager, a number of threads to use for updating indexes defined for the target table; and upon determining the data page is full, updating, in parallel, the indexes defined for the target table using the number of threads.
