Title: Appareil et procede d'extrusion, produit tubulaire et tuyau
Inventor: JAERVENKYLAE JYRI
IPC: B29C48/09
Filed: 1996-06-20
Abstract: Cette invention concerne un appareil et un procédé d'extrusion, ainsi qu'un produit tubulaire et un tuyau faits de divers matériaux. D'après cette invention, l'appareil d'extrusion comprend au moins un stator (1, 6, 10), au moins un rotor (2, 2a, 2b) et au moins un espace d'alimentation annulaire (3) situé entre le stator (1, 6, 10) et le rotor (2, 2a, 2b). Le diamètre de l'espace d'alimentation (3) décroît au moins partiellement et de manière continue dans le sens de l'écoulement du matériau plastique à extruder. Ce diamètre augmente également de manière continue au niveau d'une partie au moins de la longueur dudit espace, et dans le même sens d'écoulement. Une telle construction permet d'équilibrer sensiblement la pression qui s'exerce sur la structure de l'appareil d'extrusion, ce qui permet d'allonger la durée de vie de ce dernier. Cette invention concerne également un produit tubulaire et un tuyau faits de plusieurs matériaux différents.

Title: Process for splitting residues to recover secondary raw materials
Inventor: FELBER WALTER
IPC: B09B3/00
Filed: 1996-06-07
Abstract: In this process for reducing so far unused residues from tailings, soiled plastics from "yellow waste", strainings from sewage plants, rubbish from dumps and sand residues to obtain and recycle secondary raw materials, said wastes are subjected to a repeated cycle of wet and dry sieving, separation, sorting and classification. The clean secondary raw materials obtained are preferably conditioned in stages in an aerobic environment and, except for difficult materials, taken directly to biological, material or raw material processing plants. Conditioning the secondary raw materials also permits long intermediate storage owing to the slight degree of rotting and stink. The low investment costs make it possible to set up small plants for regional waste economies while still offering economic advantages over competing technologies. The system can be operated without subsequent deposition or mass incineration for the residue processing involving about a sixth of the partial mass flow rate of mixed plastics, composites and other materials. Residues can be made into building materials. Fine strainings are not given any prior dry mechanical treatment.

Title: Wood treatment process to prevent splitting and checking during drying
Inventor: MAKAR MARKO
IPC: F26B3/353
Filed: 1998-05-22
Abstract: A method for treating a wood piece to be dried. The wood piece comprises a complete cross-section through a tree trunk or branch and includes bark, phloem tissue, xylem tissue and heartwood and is commonly referred to as a pole. The method involves passing an electric current through the length of the wood piece for a pre-determined period and removing the bark immediately before or after the electric current treatment so that the tendency for the wood piece to split or check during subsequent air drying is reduced. The method is particularly useful for treating pine or spruce poles intended for carving into walking sticks or turning on a lathe.

Title: Turbogenerator/motor controller
Inventor: GEIS EVERETT R
IPC: H02P9/08
Filed: 1998-09-08
Abstract: A turbogenerator/motor controller with a microprocessor based inverter having multiple modes of operation. To start the turbine, the inverter connects to and supplies fixed current, variable voltage, variable frequency, AC power to the permanent magnet turbogenerator/motor, driving the permanent magnet turbogenerator/motor as a motor to accelerate the gas turbine. During this acceleration, spark and fuel are introduced in the correct sequence, and self-sustaining gas turbine operating conditions are reached. The inverter is then disconnected from the permanent magnet generator/motor, reconfigured to a controlled 60 hertz mode, and then either supplies regulated 60 hertz three phase voltage to a stand alone load or phase locks to the utility, or to other like controllers, to operate as a supplement to the utility. In this mode of operation, the power for the inverteris derived from the permanent magnet generator/motor via high frequency rectifier bridges. The microprocessor monitors turbine conditions and controls fuel flow to the gas turbine combustor. The turbogenerator/motor controller can also have an energy storage and discharge system including an ancillary electric storage device, such as a battery, connected to the generator controller through control electronics. Electrical energy can flow from the ancillary electric storage device to the turbogenerator controller during start up and increasing load and vice versa during self-sustained operation of the turbogenerator. When utility power is unavailable, the ancillary electric storage device can provide the power required to start the turbogenerator. When a load transient occurs, the gas turbine engine and the ancillary electric storage device provide the power required to successfully meet the transient.

Title: Continuously self-cleaning drum filter
Inventor: SMITH JAMES ANDREW
IPC: B01D33/11
Filed: 1998-12-21
Abstract: A continuously self-cleaning filter consists of a rotating drum filter, an oscillating high-pressure air nozzle to remove cake and particles from the filter mesh; the means to drive the drum filter and the oscillating nozzle;  and a chute to catch the material dislodged from the filter mesh and to direct it to a receiving tank.      To accomplish this, water, containing dirt particles, droplets of free oil or metal particles, oil or other contaminants encapsulated in bentonite clay, is directed onto the inner surface of the drum filter mesh, at the lowest point of its rotation, where substantially all of the water passes through the filter mesh, while the particles or cake are trapped in the filter mesh and travel to the top of the drum filter rotation, where they are blown out of the filter mesh by compressed air, onto a receiving chute, and thereby directed to a receiving tank. The clean water is collected in a separate receiver.      To this end, one end of the filter drum is solid and fixed rotatably on essentially a horizontal axle, the other end of the drum has a circular opening through which the solids bearing water is introduced and the filtered cake removed by the chute.
