Title: Circuits oscillants presentant des resonateurs coaxiaux
Inventor: NICHOLLS CHARLES T
IPC: H03B5/18
Filed: 2001-11-29
Abstract: Il y a des limites à la miniaturisation de résonateurs coaxiaux céramiques, qui ont pour conséquence de limiter la fréquence de résonance de ces résonateurs. L'une des techniques visant à doubler la fréquence efficace d'un résonateur coaxial céramique consiste à coupler chaque extrémité d'un résonateur à un oscillateur Colpitts, les oscillateurs étant équilibrés et déphasés de 180°. Durant le fonctionnement, le résonateur est divisé en deux de manière efficace avec une masse virtuelle formée au centre. Cela permet à un résonateur unique de fonctionner comme deux résonateurs avec une taille réduite de moitié par rapport à la taille d'origine. Ainsi, la fréquence d'oscillation de chacun de ces oscillateurs équilibrés est doublée en comparaison avec la fréquence d'oscillateurs similaires qui correspondent à des oscillateurs coaxiaux céramiques séparés de taille similaire. En appliquant cette technique à une conception symétrique réglée à la troisième harmonique, la fréquence d'oscillation de sortie est multipliée par six par rapport à celle d'un oscillateur correspondant à un résonateur coaxial céramique séparé de taille similaire. Cette technique peut s'étendre à toute la gamme d'utilisation d'un résonateur coaxial céramique, de sorte que, s'il est utilisé couplé à un mélangeur pompé de façon sous-harmonique qui permet de doubler la fréquence d'oscillation locale, la fréquence d'oscillation maximale augmente de façon idéale jusqu'à 60 GHz. Cette gamme de fréquences permet à des résonateurs coaxiaux céramiques d'être utilisés pour des applications à fréquence élevée telles que le système de répartition multipoint local (LMDS).

IPC: C08J9/00
Filed: 1989-11-06
Abstract: Novel compositions of silicone/polyether block copolymers are provided which are useful as surfactants in several classes of polyurethane foam production. While conventional copolymers have a polysiloxane backbone with pendant polyethers, the surfactants of the present invention are the reverse with siloxane pendants on a polyether chain. These novel non-hydrolyzable polysiloxane polyoxyalkylene copolymers which are characterized by an "inverted" structure, i.e., polyoxyalkylene backbones with lateral and/or terminally pendant polysiloxanes, represent species that are of a narrow molecular weight and compositional distribution and are free of unreacted polyether or non-modified silicone oil diluent. These surfactants are useful in various urethane foam systems and can also display aqueous wetting properties.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved anti-icing and de-icing system is provided for reflector-type microwave antennas having a paraboloidal reflector and an associated feed horn for launching microwave signals onto the reflector and receiving microwave signals from the reflector. The improved system comprises a non-conductive, insulated enclosure forming an enclosed cavity adjacent the rear side of the reflector, and radiant heating means within the enclosure for heating the rear side of the reflector with radiant energy, whereby the air in said cavity is in turn heated by heat transferred to said air from the rear side of the reflector.    The radiant heating means comprises at least one infra-red heating source, and is supplemented by a highly reflective mirror coating disposed on the inside surface of the insulated enclosure behind the heating source to direct the radiant energy emanating from the back of the heating source to all regions of the paraboloidal reflector.  Sections of highly reflective mirror coating are also provided on the rear surface of the paraboloidal reflector itself immediately in front of the heating source to divert excess radiant energy emanating from the front of the heating source and to disperse it to all regions of the paraboloidal reflector.

Inventor: EWEN JOHN A
IPC: C08F4/44
Filed: 1990-10-09
Abstract: This invention is for a metallocene compound which can be used in a catalyst system to produce hemiisotactic polymer. The compound is a bridged metallocene compound having dissimilar cyclopentadienyl groups and no bi-lateral symmetry. One example of the compound is isopropylidene(3-methylcyclopentadienyl.-1-fluorenyl) zirconium dichloride. The catalyst of this invention can be converted to an ionic metallocene catalyst by an ionizing agent, such as methylaluminoxane.      The polymer produced with this catalyst is characterized by having an isotactic structure effecting only every other asymmetric carbon atom. In the case of polypropylene, every other methyl group is on the same side of the principal polymer chain as represented by a Fisher projection. The remaining methyl groups can be either on the same side or on the opposite side of the principal polymer chain. The polymer produced with the catalyst of this invention can be used as a plasticizer.

Title: Method and apparatus for determining full load condition in a screw compressor
Inventor: RENTMEESTER PAUL C
IPC: F25B1/047
Filed: 1990-12-04
Abstract: Title METHOD AND APPARATUS FOR DETERMINING FULL LOAD CONDITION IN A SCREW COMPRESSOR     Abstract The determination as to whether an operational compressor in a multiple-screw compressor water chiller is fully loaded is made by sending a relatively long duration test pulse to the load solenoid of the compressor.  If the compressor is fully loaded, no measurable change in the current drawn by the compressor motor will be measured since no slide valve movement will have occurred and no additional load will have been placed on the compressor.  If, however, the compressor is not fully loaded at the time the test pulse is sent, the compressor slide valve will move to load the compressor to an extent such that a reliably measurable change in compressor motor current draw occurs.
