Abstract: A method for making a fabric covered foam cushion utilizing a pre-formed foam pad enclosed within a fabric bag.  The subject method includes pre-attaching an adhesive film (12) to a pre-formed foam pad (10) and subsequently inserting the foam pad (10) within a fabric bag (14) so that the adhesive film (12) is sandwiched between a portion of the inside of the fabric bag (14) and a portion of the outside of the foam pad.  Steam is forced through the fabric bag (14) to disperse and activate the adhesive film (12) so that the adhesive film (12) forms a pervious bond between the fabric bag (14) and the foam pad (10).          Following the application of steam, vacuum pressure is applied to the cushion in order to cool and cure the adhesive and also to draw residual moisture from the cushion.

Abstract: TITRE: PRINCIPE DE FONCTIONNEMENT D'UN SYSTEME GRAVITATIONNEL Mot clé: gravitation PRÉCIS: Pour la conception d'un système gravitationnel, il faut d'abord imaginer que deux poids de pesanteur égale autour d'un axe central s'équilibrent. Pour déstabiliser cet équilibre il faut créer un contrepoids sur une moitié du système. Le principe ici mentionne que l'on peut, grâce à un point d'appui extérieur, convertir de l'énergie latente et non nécessaire à l'équilibre d'un système en rotation autour d'un axe, en énergie verticale ascendante qui, appliquée sur une moitié de ce système en annule la force gravitationnelle existante et par conséquent déséquilibre le tout en créant un poids à une distance x de l'axe sur une seule moitié du système. Donc, pour déséquilibrer un système ayant des poids égaux opposés sur un axe mobile, il suffit d'annuler l'énergie gravitationnelle existante sur un côté de ce système. En autant que nous le sachions, le principe décrit ici n'a jamais été énoncé nulle part et comporte un principe antigravitationnel tout à fait unique.

Title: Improved water treatment system
Inventor: POPE DANIEL H
IPC: C02F1/68
Filed: 1992-12-14
Abstract: The present invention comprises an improved method and apparatus for treating water in heat exchange systems. The present invention automatically and inexpensively provides an effective chemical to process water systems at times and in proportion to the need for water treatment in such systems. When used in evaporative cooling systems (10), the present invention adds the treatment chemical to the system via the make-up water (44). The make-up water acquires a substantially constant concentration of treatment chemical as it is passed through a device (42) containing a treatment chemical. The constant concentration of chemical is achieved by dividing the make-up flow into two streams within the device, saturating the smaller of the two streams with chemical, and re-mixing the two streams. The biocide agent used in the preferred embodiment of the invention is prilled elemental iodine. <IMAGE>
