Title: Band-pass passive filter
Inventor: BUDAN HENRI
IPC: H01P1/203
Filed: 1989-11-29
Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a  band-pass passive  filter made  by means of microstrips  on a  dielectric substrate.  This filter is formed  by at least  three mutually  parallel microstrips, one end of which is grounded. At least two non-adjacent microstrips  are  coupled  by  a  coupling impedance Z.  The  distances  x , x ,  x ,  x   of  the fastenings, on the microstrips, of the input, coupling impedance  Z  and   output  set   the  impedances   and characteristics of  the  filter.  A  first  improvement enables the pass band to  be contracted, by means of  a high impedance, parallel  mounted on the  input of  the filter. A second  impedance,  series  mounted  on  the input, corrects  the  input impedance  modification. second improvement consists in folding the filter  back on itself to  reduce its  bulk. The  continuity of  the microstrip lines is provided  by metallizations on  the flanks of  the substrate,  and U-shaped  links  provide access channels to the filter and its fastening means.

Title: Ethylenically unsaturated, surface active urethane derivatives and process for their preparation
Inventor: HUTH HANS-ULLRICH
IPC: C09K23/52
Filed: 1990-10-19
Abstract: Abstract of the disclosure Ethylenically  unsaturated,  surface  active  urethane derivatives and process for their preparation Ethylenically unsaturated surface active urethane deriva-tives  prepared by reacting  alkyl,  aryl,  aralkyl  or cycloalkyl monoisocyanates with hydroxypolyoxyalkyleneoxycarbonylalkenes or with N-(hydroxypolyoxyalkylene)-alkenecarboxamides  in the absence of water in bulk or in inert organic solvents or optionally also in reactive diluents, which are copoly-merizable ethylenically unsaturated monomeric compounds which are inert under the reaction conditions, such as, for  example,  vinyl  esters, vinyl  aromatics,  and (meth)acrylic esters.            The  urethane  derivatives  prepared  according  to  the invention are surface active in their monomeric form and are in most cases solid or waxy or highly viscous pro-ducts. Their solubilities in water and in inert organic solvents or inert reactive diluents is highly dependent on the structure and size of the polyalkylene oxide radicals and also on the size of the hydrophobic radical at the nitrogen atom of the urethane group,  so that, according to the invention, monomeric urethane deriva-tives which are readily soluble not only in water but also in inert organic solvents can be obtained. These are polymerizable or copolymerizable via their ethylenically unsaturated acyloxy or acylamido radicals and are versatile in use for the preparation of polymers or copolymers by free-radical initiated polymerization or copolymerization.

The paper toweling is dispenser through a nip formed between first and second embossing rolls rotatably mounted within  the  dispenser.    The  first  embossing  roll  includes  a plurality of knuckles extending radially therefrom and arranged in a plurality of spaced, circumferential rows.  The second embossing roll includes a plurality of annular extensions and annular slots arranged in alternating relationship.  The spaced, circumferential rows of knuckles of the first embossing roll align with the annular slots of the second embossing roll.  Means are provided to manually rotate the first embossing roll.  The second embossing roll may be allowed to rotate freely from said first embossing roll.     As the first embossing roll is rotated, paper toweling is drawn through the nip and is embossed therein.   Because the knuckles of the first embossing roll reside in the slot of the second embossing roll at the nip in a non-interfering relationship, and  further  because  such  slots  are  continuous  about  the circumference of the second embossing roll, the second embossing roll need not be driven in registration with the first embossing roll.  Slippage of the second embossing roll with regard to the first embossing roll as paper toweling is drawn through the web will not result in breaking or tearing of the web.

Abstract: Dans le but de produire de l'électricité une variable est toujours très importante, omniprésente, nécessaire: une source d'énergie. La source d'énergie nous proviens sous plusieurs formes tel le gaz, l'essence, le nucléaire et aussi une chute d'eau. Il faut de l'énergie, quel que soit sa forme pour qu'il en résulte une puissance, une force, telle la production d'élec-rici-té. Dans l'invention ci-joint il est suggéré d'utilisé une force déjà existence permanente (souvent naturelle)pour produire une force de travail sans se servir d'aucune autre source d'énergie primaire. Il s'agit tout simplement de réinventer le moteur électrique ou la turbine, si l'on veut. Il s'agit plutôt d'inverser le processus du moteur ou de la turbine. C'est-à-dire de reprendre, de repenser, le même procédé qui a permit de créer le moteur électrique. L'électricité est produite lorsqu'une bobine de fils est agité par un aimant. Au lieu de cela il est suggéré de faire agi-ter, bouger des aimants avec l'aide d'autres aimants. Il y a deux forces possible avec les aimants: l'attraction et la répulsion. Dans l'invention ci-mentionné la Gorce de répulsion est l'énergie, que l'on exploite pour faire tourner une forme de turbine ou dynamo. L'arbre central, ou le pivot, est munit d'aimants placer dans le même sens de polarisation que les aimants "répulseurs", il en résulte une répulsion et un mouvement circulaire.
