Title: Lotion composition for imparting soft, lubricious feel to tissue paper
Inventor: WARNER ALRICK VINCENT
IPC: A61K8/00
Filed: 1994-11-30
Abstract: A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from 5 to about 15 % by weight. The lotion composition comprises plastic or fluid emoilient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an agent such as sorbitan stearates or N-cocoyl, N-methyl glucamide to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue.

Patent CA-2178730-A1 (CA)
Inventor: GROSS HEINZ
IPC: B29C48/08
Filed: 1994-12-02
Abstract: Une soupape d'étranglement réglable (6, 7, 8) permet de régler le courant volumique à l'intérieur d'un canal d'écoulement rectangulaire (3) ou d'un canal d'écoulement plat à zones marginales arrondies. Par sa structure particulière, la soupape d'étranglement ne comprend pas de plan de séparation perpendiculaire au sens d'écoulement du fluide. La hauteur (H) du canal peut être modifiée par cette soupape d'étranglement, ce qui permet de modifier le courant volumique de fluide en modifiant la résistance locale du canal d'écoulement en fonction de la largeur, sans créer des discontinuités dans le canal d'écoulement. Compte tenu de cette variation en continu de la géométrie du canal d'écoulement aussi bien dans le sens de la largeur que dans le sens d'écoulement, l'ensemble du canal d'écoulement (1, 2, 3) est exempt de zones mortes.

Patent CA-2179673-A1 (CA)
Inventor: ALA-KOJOLA JOUNI
IPC: H01P1/205
Filed: 1996-06-21
Abstract: The invention relates to a radio frequency filter based on transmission line resonators and having adjustable frequency response characteristics. The invention relates particularly to a bandpass filter in which the transmission zero, or the highly-attenuated frequency area limiting the pass band can be switched between at least two frequency values. To affect the coupling between the transmission line resonators, an electrically conductive regulating element and a switch are placed in their vicinity, and said regulating element can be connected to ground by means of said switch, thereby affecting either the capacitive or the inductive component of the coupling, depending on the location of the regulating element. Stepless adjustment can be realized by replacing the switch with a reactive component, advantageously a capacitance diode.

Title: Catalytic reactor design to reduce catalyst slumping and crushing
Inventor: BONK STANLEY P
IPC: B01J8/00
Filed: 1995-09-22
Abstract: A vertical catalytic reactor for steam reforming a reactor fuel into a product gas, the catalytic reactor containing a catalyst forming a catalyst bed. If the catalytic reactor material has a thermal coefficient of expansion greater than the catalyst, then the catalytic reactor experiences problems due to thermal cycling. During the start-up of the catalytic reactor, the temperature increase causes the catalytic reactor to expand more than the catalyst, thus, the catalyst slumps within the catalytic reactor. During the shut-down of the catalytic reactor, the temperature decrease causes the catalytic reactor to contract and crush the slumped catalyst. The catalytic reactor incorporates a design (100) for reducing catalyst slumping and crushing.
