IPC: C04B28/04
Filed: 1988-05-03
Granted: 1991-04-30
Abstract: La présente invention concerne un procédé pour la préparation d'un béton léger et isolant dont la densité après prise complète est de l'ordre de 400 kg/m3 à 1000 kg/m3, toutes les étapes ci-après définies, à l'exception des étapes de mise en forme et de prise, étant effectuées à l'intérieur d'un mélangeur à béton définissant une bétonnière. Selon un premier aspect de l'invention, l'on introduit un agent anti-retrait constitué de fibres dans de l'eau de gâchage suffisante pour compléter la préparation du béton et mélange le tout pendant un temps suffisant pour mouiller toutes les fibres. L'on introduit ensuite dans le mélange obtenu, un mélange constitué d'environ 20 à 50% en volume d'un liant hydraulique sec et d'environ 50 à 80% en volumes d'agrégats de polystyrène secs, la quantité de liant hydraulique sec étant ajustée de façon à ce que l'eau de gâchage soit au moins en quantité suffisante pour permettre une prise complète dudit liant. Enfin on mélange le tout pendant un temps suffisant pour mouiller tout le liant hydraulique et permettre une distribution uniforme des constituants. Selon un second aspect de l'invention, ou bienl'on introduit un agent anti-retrait constitué de fibres dans de l'eau de gâchage suffisante pour compléter la préparation du béton et mélange le tout pendant un temps suffisant pour disperser et mouiller la totalité des fibres, puis l'on introduit dans le mélange obtenu des agrégats de polystyrène sec et mélange le tout pendant un temps suffisant pour disperser et mouiller la totalité des agrégats; ou bien l'on introduit un agent anti-retrait constitué de fibres et des agrégats de polystyrène dans de l'eau de gâchage suffisante pour compléter la préparation du béton et mélange le tout pendant un temps suffisant pour disperser et mouiller la totalité des fibres et des agrégats. Ensuite l'on introduit dans le mélange obtenu une quantité telle de liant hydraulique sec que l'eau de gâchage soit en quantité suffisante pour permettre la prise complète dudit liant. Enfin, l'on mélange le tout pendant un temps suffisant pour disperser et mouiller tout le liant hydraulique, étant entendu que le rapport en volume du liant hydraulique sec aux agrégats secs de polystyrène est d'environ 1/4 à environ 1/1. L'invention concerne également un béton léger et isolant obtenu par la mise en oeuvre des procédés ci-dessus mentionnés. Ce béton permet, contrairement aux bétons ordinaires, d'être façonné, travaillé, cloué et/ou vissé de la même façon et avec les mêmes outils que ceux habituellement utilisés pour le bois.

Title: Purified water supply system
Inventor: BURROWS BRUCE D
IPC: B01D61/10
Filed: 1988-10-13
Granted: 1993-08-24
Abstract: An improved purified water supply  system is provided of the type including a reverse osmosis unit for producing relatively pure water from ordinary tap water or the like.   The reverse osmosis unit receives incoming  tap  water  and  produces  therefrom  separate outflows of purified water and relatively impure reject water.  The purified water is supplied from the reverse osmosis  unit  to  a  purified  water  chamber  within  a compact  storage  vessel, wherein  the  purified  water chamber is separated within the vessel by a movable barrier from a reject water chamber.  When use of the purified water is desired,  one or more faucet valves are opened to open a discharge path permitting purified water  to  flow  from  the  storage  vessel  through  a discharge  spout or the  like  for use.   An  improved control valve assembly operates in conjunction with the faucet valve  or valves to  apply  reject  water under sufficient  pressure  to  the  reject  water  chamber  to force purified water from the storage vessel through the open discharge path.   The control valve assembly maintains the pressure within the storage vessel at a pressure  substantially  less  than  tap  water  line pressure to permit use of a relatively lightweight and economical  storage  vessel  construction.     In  some embodiments, when the purified water discharge path is closed, the control valve assembly functions further to substantially  relieve  pressure  within  the  storage vessel to correspondingly minimize system backpressure applied to the reverse osmosis unit.

Abstract: ABSTRACT OF THE DISCLOSURE     A wood incising roller where the teeth are formed by grooves in the roller surface and where some of such grooves cross others.  Each cutting tooth has a knife-like gutting edge of finite length that is in one instance perpendicular to the axis of rotation of the roller and in another instance parallel to such axis.  The grooves can be formed by machine cutting, either turning or grinding or by being molded in the surface and then shaped by a grinding operation.  At least some grooves preferably spiral about the roller.  The pattern of cutting teeth and shape are determined by such variable parameters as pitch, number of thread starts, angle or cutter, depth of cut and lead angle.  An incisor for lumber or veneer consists of two rollers at least one of which is as described in the foregoing.  The grooves can be filled or partially filled with an elastic compressible material.  The incising roller of the foregoing also is used in combination with a veneer lathe.

Title: Golf ball
Inventor: SULLIVAN MICHAEL J
IPC: A63B37/12
Filed: 1988-12-15
Granted: 1994-03-15
Abstract: ABSTRACT      The subject invention relates to golf ball technology, and more particularly, golf ball cover technology.  The invention is concerned with a particular mixture of ionic resins as a golf ball cover composition.           Ionomers have been widely used as golf ball cover materials for the past 15 years.  While these ionomers are very durable, they have a deficiency as a golf ball cover material in that they tend to be hard. This invention is concerned with a mixture of a hard ionomer with a soft ionomer in order to produce a golf ball cover composition wherein the cover is softer than the prior art ionomer covers.           A golf ball covered in accordance with this invention is durable and a skilled golfer can impart back spin to the ball in play.
