Abstract: A breakaway member for a sign-stand having a two piece mast that supports a sign includes a first end that connects to a first mast piece which is secured to the sign, a second end that connects to a second mast piece, and a breakaway section that fractures therethrough upon impact thereby carrying the first end, the first mast piece and the sign away from the second mast piece. In a preferred embodiment, the breakaway member has a generally I-beam shaped cross-section. The first and second mast pieces have a generally rectangular and hollow cross-section. The first end of the breakaway member is disposed in the first mast piece, the second end of the breakaway member is disposed in the second mast piece, and the breakaway section is located between the first and second mast pieces.

Abstract: A system for generating web pages includes a web server that receives requests from a web browser. The web server then checks a primary cache to see if a previously generated web page exists in the primary cache. If so, the web page is returned to the user. Otherwise, the web server checks a JIT cache to determine if a previously generated JIT cache file exists. The JIT cache file will have been previously processed in a manner such that all tag except for specially designated retain tags have been replaced with data values. The retain tags are then processed to provide what are typically user specific values, and the generated web page is returned to the requester. If neither a primary cached file or a JIT cache file exists, the system creates will create one. A primary cache file is created if no retain tags are present in a template file for the web page. Otherwise a JIT cache file is created.

Abstract: A bracing sleeve which includes a base portion and a cover portion. The base portion of the sleeve is affixed along a bracing surface of a flexible sign. The base portion includes a batten recess for receiving the terminal end of a batten. The batten recess is defined by walls disposed along longitudinal sides of the base portion in opposing relation and extending outwardly from the base portion. The walls define tracks along the base wall longitudinal sides. The cover portion includes a recess side and an exterior side, the cover portion is in sliding engagement with the base portion. The cover portion is movable between a first position wherein the batten recess is exposed, and a second interlocked position wherein the batten recess is enclosed by the cover portion. The cover portion and said base portion include releasable interlocking elements which cooperate to releasably interlock the cover portion in the second position.

Abstract: The invention relates to a novel design of a lifting column, especially for patient tables or for industrial applications, with at least one lifting cylinder designed as a hydraulic cylinder at least for one vertical stroke and with at least one guide assigned to at least one lifting cylinder for guidance in the direction of the stroke of the lifting cylinder.

Abstract: Human serum albumin is made by culturing a bacterium (e.g. E. coli) capable of providing for the stable maintenance of a plasmid containing an inducible promoter (e.g. P.sub.trp), a ribosome binding site (e.g. that of the CII gene of bacteriophage lambda not containing the t.sub.R1 sequence), and the human serum albumin gene possessing an ATG initiation codon at the 5' end.

Abstract: Human serum albumin is produced by culturing a bacterium (e.g. E. coli) capable of maintaining a plasmid containing an inducible promoter (e.g. P.sub.trp) upstream of the penicillin amidase promoter, the ribosome binding site of the penicillin amidase gene and the penicillin amidase signal peptide, fused with the structural gene for human serum albumin.

Abstract: A sign panel is connected to a support frame therebelow by a resilient strip whose width is substantially greater than its thickness so that the sign panel may deflect in strong winds as permitted by the resilience of said strip. The effective length of said strip and hence the resilience thereof may be adjusted so that the maximum length of the strip is utilized under high wind conditions.
