Appl. No.:

10/246650

Inventors:

Stephen Rogers - Johnston RI, US

International Classification:

A47G001/16

US Classification:

040/747000, 428/007000

Abstract:

The present invention provides an ornament with a rotating display that has an outer frame assembly that includes two integrally formed pivot supports and a display assembly disposed within the frame assembly having two opposing pivot members integrally formed on the display assembly that pivotably engage the pivot supports. The integrally formed pivot supports include a central ring and two connecting arms, each connected to the central ring at two points on the diameter of the ring on one end and the frame member on the other. The central ring and connecting arms are formed integrally with the frame member by stamping or photochemically blanking the shape and rotating the ring into its final position by twisting the connecting arms. By forming the pivot supports in this manner, the opening in the central ring is maintained substantially in alignment with the plane of the frame member. This allows the rotational axis of the display assembly to remain in alignment with the plane of the frame member when the display assembly is mounted in the pivot supports.

Abstract:

A recombinant plasmid which may be used for propagation of cloned cDNAs and also for the in vitro synthesis of RNA which is an exact copy of the natural sequence, wherein the transcript is devoid of vector-derived sequence. The novel vector was generated de novo by genetic engineering procedures using a synthetic double strand oligodeoxyribonucleotide fragment and a larger DNA fragment derived from plasmid pSP64. The vector, plasmid pHST-O, carried by Escherichia coli HB101, deposited with the ATCC on Dec. 30, 1985 and designated ATCC 53381, is distinguished from other vectors containing the SP6 promoter by the following characteristics: it contains a unique site for the restriction endonuclease BglII; the engineered GBlII site overlaps the downstream border of the SP6 promoter sequence; and the presence and positioning of the BglII restriction site permit insertion of cDNA molecules in such a way that transcription by the SP6 RNA polymerase begins exactly at the 5' terminus of the RNA, providing that the 5' terminal nucleotide of the mRNA transcript is a guanosine (G) residue, thus excluding the transcription of nucleotides derived from the vector. The novel vector permits synthesis of RNA molecules which have a defined 5' terminus and which are devoid of vector-derived sequence. The vector has potential use in research in molecular biology and in the in vitro production of RNA and proteins.
