Patent CA-2054286-A1 (CA)
Inventor: KANNENGIESSER WERNER
IPC: B29C63/42
Filed: 1991-10-25
Abstract: A fuse having a protective jacket is utilized, for example, in petroleum exploration at large depths where the fuse must withstand high temperatures and pressures. The jacket is produced from a shrinkable hose that is shrink-fitted onto the unfinished cord which latter contains an explosive. The hose consists preferably of radiation-crosslinked polyethylene. The use of a shrink-fitted hose eliminates long preparation and curing times for the synthetic resin jacket. The process temperatures required during heat shrinking are no threat to the safety against ignition of the explosive. It is possible in accordance with the process to manufacture, in particular, fuses for high pressures and high ambient temperatures, without any problems.

Title: Methods and apparatus relating to micropropagation
Inventor: ALLARD JANE M
IPC: A01H4/00
Filed: 1990-06-29
Abstract: In a method of micropropagation, a series of horizontal cuts are made through a mass of fairly straight stemmed plantlets (11) growing from a gelled nutrient medium (12), to obtain cut crop parts (17) containing on average at least one tip or node per cut portion. At each cut, the crop parts (17) are transferred in bulk for example by air-flow or gravity to a fresh gelled nutrient medium (12A), where they are planted by random scattering. In a final stage, harvesting of propagules (56) from plantlets (11) is achieved by combing through the crop with a comb (39), and separating the propagules by producing relative movement of the comb (39) away from the gelled medium (12).
Patent CA-2080866-A1 (CA)
Inventor: VIGIL DENNIS M
IPC: A61M29/02
Filed: 1992-10-19
Abstract: A stenotic dilation device includes a plurality of elongated atherotomes with cutters mounted on the outer surface of a flexible balloon along predetermined crease lines. The atherotomes are aligned along the longitudinal axis of the catheter. The ends of the balloon are attached to a hollow catheter tube over fluid ports in the catheter which establish fluid communication between the catheter and the internal chamber of the balloon. Fluid flow into and out of the chamber will inflate and deflate the balloon. When the balloon is deflated, retraction of the atherotomes toward the longitudinal axis of the catheter causes the creases and lines to form flaps of the balloon membrane material between adjacent atherotomes. In such deflated configuration, the flaps, rather than the cutters of the atherotomes, contact the vessel wall as the device is manipulated into position adjacent a stenotic site. On inflation of the balloon at the stenotic site, the atherotomes are urged against the stenosis to incise the stenosis. The incisions relieve pressure in the wall of the vessel and thus enhance dilation of the vessel by the balloon. After dilation, the balloon is deflated and the device is removed.
