Patent CA-2213643-A1 (CA)
Title: Cable splicing device
Inventor: BUTLER RICKEY
IPC: H01R4/18
Filed: 1996-02-23
Abstract: A connector system is provided for connecting conductors of high tension cables during splicing between cables. Each connector comprises lugs having ferrule portions which are crimped to the ends of conductors to be joined and part cylindrical lug portions which are bolted together through filler or connector plats to form a smoothly contoured connection free from edges or projections providing high electrical stress concentrations. The connector plates enable two connections to be joined in parallel to provide branch connections: a smoothly contoured lug adaptor replaces a fourth lug if only a single branch connection is to be made. Smoothly contoured and recessed nuts and bolt head covers contribute to the smooth external contour of the connection.

Title: System and method for mitigating cross-saturation in optically amplified networks
Inventor: NEWSOME GEORGE W
IPC: H04B10/572
Filed: 1997-09-11
Abstract: A system and method of protecting all the amplifiers in a link between wavelength routing network elements of an optical network. According to the invention, an optical control channel is added before a plurality of optical amplifier, preferably the first amplifier, in a link. To prevent improper loading of downstream links, the control channel is stripped off at the next wavelength routing network element. The power of the control channel is automatically adjusted using a fast feedback circuit to hold substantially constant the total power of the signal channels and the control channel at the input of the first amplifier following the feedback loop. In this manner, channel loading of all optical amplifiers in the link is maintained substantially constant, and the incidence of error bursts, as might otherwise result when one or more channels are added or dropped due to a network fault or reconfiguration, is substantially reduced.

Patent CA-2219323-A1 (CA)
Inventor: HAMALAINEN JARI
IPC: H04W72/04
Filed: 1996-04-24
Abstract: Etant donné que la caractéristique d'un système de transmission de données à grande vitesse dans un réseau de radiocommunication cellulaire est un fonctionnement largement unidirectionnel, on décrit une connexion asymétrique pour résoudre ce problème. Ladite connexion offre une capacité de transmission importante dans le sens où est acheminé l'essentiel du flux de données alors que, dans l'autre sens, la capacité de transmission est inférieure. On dispose de manière asymétrique les intervalles de temps pour la transmission et la réception afin que transmission et réception ne s'effectuent pas simultanément. Au moment où la connexion est établie, la station mobile informe le réseau de sa capacité maximum pour la réception et la transmission, ce qui permet au réseau de déterminer une configuration appropriée des intervalles de temps. En premier lieu, une connexion symétrique comprenant un nombre spécifique de paires de canaux est attribuée de la même façon qu'avec la transmission de données à commutation de circuit à grande vitesse dans la technique existante. Dans une phase ultérieure, seuls les intervalles de temps requis pour les sens de transmission et de réception sont utilisés, les intervalles de temps non sollicités restant attribués.

Abstract: [Problem]  To enable the transfer coating of an elaborate and fine pattern of hot melt adhesive onto a workpiece, and to extend the service life of the first roll and the doctor blade. [Solving Approach]  To form a predetermined pattern of hollows on the surface of the first roll and at the same time to form a pattern of protrusions on the surface of the second roll. that differs from that on the first roll.  By this approach, the adhesive is transferred only to the protrusions of said second roll even if excess adhesive remains in the hollows of the first roll and even if some adhesive remains in areas other than the hollows. Accordingly, a necessary and sufficient: amount of adhesive can be transferred onto the workpiece without the simultaneous transfer of any stains.  In this way, an elaborate, fine, and clear pattern without any spreading and/or loss of shape can be obtained.  Furthermore, there is no need to intensively scrape excess adhesive off the surface of the first roll with the doctor blade, which in turn allows the force used to press the doctor blade against the first roll to be reduced, the result being an extension of service life for both the first roll and the doctor blade.

IPC: A01C1/06
Filed: 1998-05-01
Abstract: Embodiments of a coating composition and coating method for seeds are described, the coating including molybdenum and a sulfur-containing component and being for improving seed and seedling performance. The preferred molybdenum source is molybdenum trioxide, and the preferred sulfur source is gypsum. After planting, the seed coating provides protection for the seed during dry spells until moisture is received and seed growth is established. During the establishment period for legumes, the invented seed coating serves as a protective coat for the seed under adverse growing conditions, such as temperature and moisture extremes. Within a few days of emergence of legume seedlings, the invented coating stimulates and/or feeds the Rhizobium bacteria that is in place on the seed and speeds up formation of the Rhizobium, which fixes/feeds nitrogen to the plant. The coating and method may also include inoculation with Rhizobium, and, optionally, other nutrients, pesticides, or herbicides and a binder.

IPC: E04D15/06
Filed: 1998-07-29
Abstract: A device for applying a vapor retarder film onto purlins on a roofing system has a base with rollers and guides for directing the base across the purlins.  The base has a fore end and an aft end with a pair of side members. The base moves across the purlins such that the side members remain in a fixed spaced apart relationship wider than the spacing between the pair of purlins. A vertical member attached to each of the side members provides a means for mounting a web of the vapor retarder film on a roll above the base and the adjacent pair of the spaced apart purlins. Adhesive is dispensed onto the edges of the web and the web is payed out and guided onto the purlin so that the edge of the web having the adhesive is put into adhesive engagement with the top surface of the purlins and the film sealingly spans the interval between the adjacent purlins. By use of a plurality of these devices acting in parallel, a method of applying the web to the roof purlins is taught.
