Patent CA-2348654-A1 (CA)
Inventor: VAN EIJNDHOVEN MARIA DE JESUS
IPC: C08G69/28
Filed: 1999-11-30
Abstract: A two-step process for the production of polyamides from .alpha.,.omega.-dinitriles and .alpha.,.omega.diamines involving the catalytic hydrolysis of the .alpha.,.omega.dinitrile by addition of water with simultaneous purging of the reactor (i.e., venting of ammonia and water vapor) in the first step followed by polymerization by addition of the .alpha.,.omega.-diamine to the hydrolysate in the second step. Such a process is particularly useful in the production of poly(hexamethylene adipamide), i.e., nylon 6,6, from adiponitrile and hexamethylene diamine using lower catalyst levels during hydrolysis and resulting in reduced levels of bis(hexamethylene)triamine, BHMT, in the polymer.

Abstract: An apparatus for charging containers includes a first conveyor for advancing items; a second conveyor for continuously advancing containers; a charging device including first and second chutes each having an inlet adjoining the discharge end of the first conveyor and an outlet positioned above the second conveyor. The first and second chutes adjoin one another in a direction parallel to the conveying direction of the second conveyor. A drive shifts the charging device and the discharge end of the first conveyor relative to one another for selectively aligning the inlet of the first chute or the inlet of the second chute with the discharge end for selectively introducing items from the first conveyor into the first or second chute. A sensor detects items advanced on the first conveyor. A control device is connected to the sensor and the drive for operating the drive based on the sensor signals.
Patent CA-2351440-A1 (CA)

IPC: H02K3/40
Filed: 2000-09-14
Abstract: The invention relates to a corona shielding arrangement for the stator winding of high voltage rotary machines with round-wire winding in combination with slot portion insulation. Also disclosed is a method for the production of said corona shielding arrangement. The object of the invention is to create an overhang corona shielding and provide a method for the production of said shielding for a stator winding which safely controls electrical stresses, especially those arising at the end of a slot during testing with high alternating voltages and surge voltages and when a switching operation is carried out. Contact between the slot portion shielding and overhang corona shielding is improved and higher partial discharge inception voltages are created. According to the invention, the corona shielding arrangement is structured in such a way that the conductor and semi-conductor shielding materials are disposed both outside and inside the laminated stator core. The semiconductor material for the overhang corona shielding is composed of a flat semiconductor corona shielding material cut into strips on both sides at the level of the slot, and optionally, also at the base of the slot on the lining thereof. The point of contact between the conductor and semiconductor corona shielding material is located inside the laminated stator core. According to the inventive method, the semiconductor corona shielding materials which are to be arranged on the conductor corona shielding material are only partially glued. The winding is introduced gradually into the slots via the opening thereof. The end winding is subsequently integrated, whereby the lining of the slot projecting therefrom is also insulated up to the laminated stator core and the semiconductor corona shielding material must be kept at a distance from the lining of the slot. The semiconductor corona shielding material is then arranged on the insulation of the end winding and secured by means of an adhesive strip or cover band which is placed over the insulation of the end winding.

Title: Drywall corner finishing device
Inventor: STIBOLT PAUL E
IPC: E04F19/04
Filed: 1999-02-05
Abstract: A finishing device used to form a comer between two panels of drywall has a flexible joint (100) along a predetermined axis. Two wings (102, 104) are connected to and extend outwardly in a diverging relation from the flexible joint (100) to form a corner having an adjustable angle. Each wing (102, 104) has a front surface (106), a rear surface (108), and an edge distal (204) from the flexible joint (100). This edge (204) abuts one of said drywall panels and has a thickness of the drywall panel. Alternatively, the edge (204) has an adjustable thickness to fit various thicknesses of drywall panel. A layer of primer or adhesive laminate is applied to the front surface of the wings so that paint can bond to the front surface. The finishing device is capable of forming both inside and outside corners. To form inside comers, the finishing device bends along the flexible joint (100). To form outside corners, strips parallel to the flexible joint (100) are removed from the rear surface of the wings (102, 104) and the finishing device is folded along the openings thus created.

Title: Method and device for producing a product made of strip tape, especially a medical product and/or a product containing active substances as well as fillable receptacles or poucheswhose edges can be sealed
Inventor: HOFFMANN HANS-RAINER
IPC: B31B50/18
Filed: 2000-05-31
Abstract: A process for manufacturing an active substance-containing product from strip tape. A broad web material roll is mounted, loosely rotatable, on a take-up mandrel. The web of material is drawn, in its entire width and without tensile stress, from the roll of material by a vacuum roll, and is separated into individual strips in the negative pressure zone of the vacuum roll by rolling a multiple circular knife roll. At the end of the negative pressure zone of the vacuum roll, each strip is drawn from the vacuum roll and is introduced in a take-up channel and continuously conveyed by negative pressure. Each strip is turned on its way to or through the channel by about 90°. At the end of the channels the strips are led at least two at a time, and conveyed further in a groove for further processing to form the finished product.
