Patent AU-2001293073-A1 (AU)
Title: Side valve arrangement for an internal combustion engine
Inventor: BLAIR GORDON
IPC: F02B23/08
Filed: 2001-09-26
Abstract: A side valve internal combustion engine provided with at least one combustion cylinder having a piston. At least two intake valves and at least one exhaust valve are provided for each of the combustion cylinders. In order to maintain a compact engine and provide a nozzle-type combustion chamber, the intake valves and exhaust valve are locate to one side of the combustion chamber in the engine block. The exhaust valve is further located at a greater distance from the combustion cylinder than the intake valves in order to decrease heat distribution on the cylinder walls. The nozzle-type chamber provides for efficient flow of gases within the engine.

Inventor: NIEMEYER ARMSTRONG FERNANDO AU
IPC: F01N5/04
Filed: 1990-09-21
Abstract: Exhaust system for internal combustion engines whose purpose is to take advantage of the energy normally wasted by the engine, in order to create vacuum inside the pipes (1) at the moment the exhaust valve opens. Vacuum which will suck out the gases from the cylincer, diminish engine temperature, reduce noises and improve engine efficiency. The elimination of all exhaust pressures is accomplished by means of a turbine (2), operating on the principle of pressure wave decomposition.

Title: Modification d'une composition en lignine de gymnospermes
Inventor: ELLIS DAVID DUNHAM
IPC: C12N15/82
Filed: 2000-01-31
Abstract: L'invention concerne un procédé de préparation d'une plante de gymnosperme transformée ou un précurseur de plante (cellules, cals, embryons, coléoptiles, graines ou semis) dont le génome contient au moins un transgène pouvant être exprimé ce qui se traduit par la modification de la composition en lignine de la plante la rendant ainsi plus attractive en termes commerciaux. Un des transgènes pouvant être exprimés est de préférence le gène férulate 5-hydroxylase ou un gène codant pour une enzyme dont l'activité enzymatique est sensiblement semblable à l'enzyme F5H lors de sa transformation en levure. Aussi, après sa transformation en cellules de plante on obtient une lignine contenant du syringyle ou d'autres résidus de lignine dans un gymnosperme.

IPC: E21B1/02
Filed: 2003-07-17
Abstract: L'invention concerne un dispositif d'entraînement permettant d'installer un tuyau ou tubage sans utiliser de moyens hydrauliques ou pneumatiques, par capture du mouvement rotatif du train de forage. Le dispositif d'entraînement est placé au niveau de l'extrémité supérieure du tuyau (42) en cours d'installation et le train (2) de forage passe au centre du dispositif. Le train de forage tourne, avance ou se rétracte librement dans le dispositif d'entraînement, jusqu'à ce que le dispositif d'entraînement se trouve fixé (4) au train de forage lorsque nécessaire. Lorsque le dispositif d'entraînement est fixé au train de forage, la force de rotation du train de forage et toute force dirigée vers le bas appliquée sur le train de forage sont capturées et utilisées pour installer le tuyau. Le dispositif d'entraînement utilise la rotation du train de forage pour frapper le tuyau, entraînant le tuyau vers le bas. Le dispositif d'entraînement utilise toute force dirigée vers le bas appliquée sur le train de forage pour maintenir une pression vers le bas sur le tuyau.

IPC: G21F9/28
Filed: 1990-06-21
Abstract: ABSTRACT OF THE DISCLOSURE     Radioactively contaminated objects are placed into a borofluoric acid bath following a rough spot test and are precipitated in a measurable geometry on the cathode plates in the course of an electrolytic process, for example.  In the course of the subsequent testing, the metals lying below a pre-determined maximum value of radioactive emissions are separated and supplied to the waste reclamation.  The materials lying above this threshold value during the spot testing are first decontaminated and then placed in the acid bath.  The borofluoric acid is not used up in this process and remains in the system.  It is possible to use already radioactively contaminated boric acid from pressurized water reactors, to which it is merely required to add fluoric acid and to distill, for generating borofluoric acid.  The method in accordance with the invention reduces the radioactive waste and reduces the testing and administrative effort required for the release of the non-radioactive materials.

Inventor: BIRBECK THOMAS S H
IPC: H01B13/02
Filed: 1990-07-05
Abstract: ABSTRACT     In a method of manufacturing a stranded conductor for use in an electric power cable, the cross-sectional shapes of wires being drawn towards or through a rotatably driven lay plate by which the wires are laid helically in a layer around the axis of the conductor are so modified that, on emerging from the lay plate and passing into at least one die downstream of the lay plate, the wires of modified cross-sectional shape fit tightly together and, if present, around a central wire or a preceding layer of helically applied wires.  The wires of each layer preferably are initially of the same cross-sectional shape and size as one another, e.g. approximately circular, and, preferably, the modified cross-sectional shapes imparted to the wires of each layer are the same as on  another, e.g,  approximating to a sector of an annulus.  No compacting of the wires is required in the die or dies and, as a consequence, a capstan drawing the wires through the die or dies is not subjected to an undesirable load.
