Title: Liquid ring machine
Inventor: TRIMBORN PETER
IPC: F04C19/00
Filed: 1994-01-11
Abstract: When liquids are conveyed together in the liquid ring of a liquid ring machine (1), there results an increased power requirement and a deterioration of the running characteristics of the rotor (8).

Patent CA-2158950-A1 (CA)
Title: Organic hydride/metal hydride heat pump
Inventor: KESTEN ARTHUR S
IPC: F25B17/12
Filed: 1993-12-13
Abstract: A heat pump that includes organic hydride (12) and metal hydride (2) systems cools a conditioned space (6) by transferring heat from the conditioned space to a metal hydride bed (4), thereby decomposing a metal hydride in the bed to form H2. The H2 flows to a vapor space (14) in the liquid hydride system (12) and reacts with a dehydrogenation product at a catalytic surface (32) in the vapor space to form an organic hydride and an exothermic heat of reaction.  The heat pump also may be used to upgrade waste heat by transferring heat from a relatively low temperature heat source to decompose the metal hydride. The exothermic heat of reaction may then be removed from the vapor space and used for space heating.  In both embodiments, the metal hydride bed (4) may be regenerated by supplying an endothermic heat of reaction to the catalytic surface (32), thereby dehydrogenating the organic hydride to form H2. The H2 flows to the metal hydride bed (4) and reacts with the metal hydride bed to regenerate the metal hydride. Alternately, the metal hydride bed (4) may be regenerated by flowing a liquid mixture that includes the organic hydride into a reaction zone (38) having a dehydrogenation catalyst (42) and supplying an endothermic heat of reaction to the reaction zone, thereby dehydrogenating the organic hydride to form H2. As before, the H2 flows to the metal hydride bed (4) where it regenerates the metal hydride.

Abstract: Système de palier radial à butée à deux paliers hydrostatiques (3, 4) radiaux à butée, mobiles dans le sens axial par rapport à un logement (2) de palier qui les entoure. Chaque palier radial à butée comprend une bride (5, 6) reliée à l'axe (1). La bride comprend une surface d'appui (5a, 6a) et un palier (7, 8) de chambre de rondelle pourvu d'une surface (7a, 8a) opposée à la surface d'appui (5a, 6a), dans laquelle se trouve une gorge (7b, 8b) de rondelle, la surface (7a, 8a) et la surface d'appui (5a, 6a) formant ensemble des fentes de serrage interne et externe de chaque côté de la gorge de rondelle. La surface d'appui et la rondelle forment ensemble une chambre (7b, 8b) de rondelle dans laquelle un fluide hydraulique est introduit sous pression à partir d'une source de fluide hydraulique. Le palier (7, 8) de la chambre de rondelle constitue, avec le logement (2) de palier, une chambre (13, 14) qui est soumise à une pression hydraulique et qui comprime le palier (7, 8) de la chambre de rondelle (7, 8) contre la surface d'appui (5a, 6a), les deux paliers (7, 8) de chambre de rondelle étant comprimés dans des directions réciproquement opposées. Un moyen, tel qu'une soupape pilote (17), est agencé de façon à agir conjointement avec un émetteur/détecteur (21) servant à détecter la position de l'axe (1) par rapport au logement (2) de palier, afind de réguler la quantité de fluide hydraulique alimentant la chambre de rondelle respective (13, 14) ainsi que la pression hydraulique agissant sur le palier respectif (3, 4), ce qui permet à des charges d'importance variable d'être appliquées dans des directions variables sur l'axe (1) tandis que l'aptitude de déplacement axial de ce dernier est maintenue. Au moins une bride (5, 6) peut être démontée de l'axe (1), et les surfaces d'appui (5a, 6a) sont orientées dans des directions opposées, chacune formant un angle principalement non perpendiculaire par rapport à l'axe (1).

Title: Skin-cleansing agents, methods of preparing them and their use
Inventor: DANIEL GUENTER
IPC: C11D3/43
Filed: 1994-10-20
Abstract: The invention concerns water-containing skin-cleansing agents in liquid, paste or cream form designed to remove strongly adhering dirt, the agents containing anionic and/or amphoteric and/or non-ionic surfactants as wash-active substances, thickeners, at least one abrasive plus, optionally, auxiliaries for regulating the appearance consistency, odour and stability such as pigments, fragrances, stabilizers and preservatives. The agents are characterized in that the only solvent they contain is di-n-butyl and/or diisopropyl adipate. The agents are prepared by thorough mixing of the ingredients, the mixture optionally being heated. If a C8-C16 fatty alcohol is added as a consistency regulator, heating of the mixture becomes unnecessary.  Furthermore, the addition of a fatty alcohol enhances the cleansing action.  The invention also concerns the use of such skin-cleansing agents, the agent first being spread on to the skin without the addition of water or with the addition of a small quantity of water, and the cleansing process continued and completed by rinsing with water.
