Title: Tobacco cartridge and device for transferring a tobacco charge from a tobacco cartridge into a cigarette paper wrapper
Inventor: CREUZBURG PETER
IPC: A24C5/40
Filed: 1992-03-20
Abstract: ABSTRACT      A tobacco cartridge having a generally cylindrical tobacco charge surrounded by a sleeve made of smokable but not drawable material.  At its rear end, the cartridge continues as a cylindrical hollow section, which is made of a tubular material of relatively higher stiffness and which can thus be securely gripped when it is desired to transfer the tobacco charge from the tobacco cartridge to a sleeve made of cigarette paper.

Abstract: A trocar assembly includes an elongate trocar device and a surrounding cannula.  The trocar device incorporates an electrosurgical cutting element which is used to make a guide hole for the cannula and thus enables the remainder of the trocar assembly to enlarge the puncture.  An electronic control circuit senses the current flow to the cutting element and, when the trocar device breaks through the wall of the organ being cut, this circuit cuts off the connection to the associated electrosurgical generator.  Further control circuitry prevents a surgeon from resuming electrosurgery until a predetermined time period has elapsed.  Multiple trocars of different diameters are provided for the same assembly.

Title: A plant and method of modification
Inventor: TEASDALE ROBERT D
IPC: C12N9/22
Filed: 1991-09-26
Abstract: A method of modifying a plant to increase vegetative growth of commercially valuable plant structures at the expense of non-essential and non-commercial structures is provided. A cDNA library of reproductive-bud mRNA of P. radiata is produced and screened against cDNA prepared from vegetative buds, and non-hybridising colonies were selected. Candidate clones were then selected for the presence of genes expressed in both male and female buds and which expressed on induction by gibberellin A4/7. One clone contained a cDNA corresponding to a gene having the characteristic of early appearance and highly specific expression in male and female reproductive bud development, and the corresponding genomic DNA  sequence including the tissue specific promoter of the gene was obtained. The gene was modified by fusing a portion of the gene including the tissue-specific promoter of the gene with a structural gene for a ribonuclease. Candidate gene constructs were used to transform Pinus radiata shoot forming tissues. Explants from successful transformants were screened for expression of the ribonuclease gene upon induction.
