Title: Disposable hypodermic syringe - has inner snap connections which prevent further use
Inventor: BRANDT STEFAN
IPC: A61M5/315
Filed: 1990-11-28
Abstract: In the assembly of a disposable hypodermic syringe, the piston (4, 5) is secured to the piston rod (7) through two snap release mountings (15;13, 16), each with at least one sprung coupling which, in the coupled setting, is distorted elastically in a seating grip at the coupled section.  The coupling and seat of the first snap connection (15) withdraws the coupling from the seat when the piston (4, 5) is raised, its distortion is relaxed, while the second snap connection (13, 16) remains coupled.  When the piston (4, 5) is depressed, the second snap connection (13, 16) detaches the coupling from the seat and the relaxation of its distortion gives an uncoupling action.  The piston (4, 5) has at least one axial passage opening (14), with a larger clear cross section than the axial lie of the coupling (15) in the disengaged setting.  The circumference of the piston plate plunger (8) is held under radial tension through the inner surfaces of the cylinder wall. ADVANTAGE - The syringe is easily and economically produced and assembled, and can only be used once as the piston plunger cannot be retracted after depression.

Title: Prodn. of pathogen-resistant organisms, esp. plants - by introduction of chitinase gene giving plants with increased resistance to attack by pathogenic fungi
Inventor: LOGEMANN JUERGEN DR
IPC: C12N9/24
Filed: 1991-05-24
Abstract: Prodn. of pathogen-resistant organisms is effected by introducing a chitinase gene under the control of a transcriptionally active promoter into the genetic material of an organism. An exogenous (esp. bacterial) chitinase gene is pref. used, esp. a Serratia marcescens gene coding for coupled exofendochitinase activity. The S. marcescens ChiS gene has been isolated (from an unspecified source) as a 1-8 Kb DNA fragment. The ChiS gene is present as a pLChiA insert in E. coli A5178 (Phytopathol., 79, 1246 1989). Fusion of the ChiS DNA fragment with the cauliflower mosaic virus 35S promoter yields a chimeric 35S-ChiS gene, which is cloned in pLS034 and used to transform tobacco and potatoe plants via Agrobacterium tumefaciens LBA 4404. Similarly, fusion of ChiS with the wound- and pathogen-inducible wunl promoter yields a chimeric wunl-ChiS gene for transformation of tobacco and potato plants. USE - The process may be used to produce transgenic plants with increased resistance to attack by pathogenic fungi, e.g. Rhizoctonia solani in the case of tobacco plants
