Title: Device for enriching water with co- gas in order to generate carbonated water
Inventor: NOTAR ROBERT
IPC: B01F15/00
Filed: 1993-08-25
Granted: 1997-01-07
Abstract: Apparatus including a circulating pump inside a carbonator tank which blends CO2 with still water and which is started and stopped for predetermined time periods in repetitive cycles having an on/off ratio ranging between 1:10 and 1:20. A timing circuit controls the operating and non operating times of the circulating pump so that sufficient carbonation of the water with CO2 gas is achieved along with the formation of an ice bank on the cooled wall of the storage tank. During intervening periods when the circulating pump is not operating, the carbonated water arranges itself in layers according to its density so that the relatively warmer water sinks while the colder water together with any ice particles or small pieces of ice floating therein join together, becoming fixed to the ice bank in the upper portion of the carbonator. During the next operating cycle of the circulating pump, these particles are frozen together and become relatively harmless to the extent that the shutoff valve and output carbonated water line remains unobstructed. Whenever carbonated water is removed from the storage tank or fresh water is supplied to the storage tank, the circulating pump is again started for an additional on-period time interval which is greater than the normal on-period.

Abstract: Instead of creating hand railings by joining together sections of rectangular hollow tubing using mitre cuts and welding of the abutting cut ends, a metal knuckle is welded to the straight ends of such tubing.  The knuckle has a body with a rectangular cross-section and in profile a circular sector with an included angle less than 180°.  Each end of the knuckle is formed as a pyramidal frustum that is adapted to enter the straight end of the tubing.  A notch of generally triangular cross-section is created to hold welding bead between an end of the tubing and a respective frustum end of the knuckle.  The notch size increases with the thickness of tubing inserted over the frustum end, and filling the notch with welding bead will automatically increase the joint strength as tubing thickness increases.

Title: Treating earthenware bodies
Inventor: MACMULLEN PAUL NEIL
IPC: C04B41/49
Filed: 1993-10-15
Granted: 2004-08-24
Abstract: A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellant material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellant material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.

Abstract: The punch unit comprises a punch driver connected with a punch which on its back end has a base. Furthermore, safeguarding members which keep the punch and the punch driver free of relative  rotation during  the  stroke  of  the  punch,  and  a pre-loaded compression spring which during the stroke of the punch can be compressed between the base and a guide bushing receiving the punch so that it cannot be rotated, but is axially displaceable, are part of it.  To obtain a simpler and quicker assembly and disassembly of the punch it is provided that the pressure spring is maintained under pre-load in the guide bushing which is embodied as one or several pieces.  A catch releasably supported on the rear end of the guide bushing and releasably engaging a recess, open toward the back, in the circumferential surface of the punch driver head prevents the punch driver head from jumping toward the back out of the guide bushing.

Abstract: Propylene homopolymers and copolymers formed by metallocene catalyst system exhibit generally lower melting behaviour than previous propylene polymers. This lower melting behaviour will be of use in the fabrication and use of fibers and fabrics that depend upon either lower melting behaviour in general or upon a melting point differential between two fabrics or fibers to achieve bonding. Such fibers are, for instance, chenille or tufted cord, core and sheath. Fabrics such as spunbonded and meltblown, when combined in SM or SMS fabrics will show bonding at lower temperatures with fewer pinholes. Such fabrics may also be bonded by adhesives such as hot melt, water based and extruded polyolefins. Combinations of Ziegler-Natta catalyzed and metallocene catalyzed polymers are contemplated.

Abstract: A fiberglass or other material skin is applied to a composite airfoil structure (2) in a mold assembly (22) having a partially compliant caul plate component which defines the shape of the lower surface of the airfoil. The caul plate component includes a first portion (34) which is essentially rigid and which covers the leading edge (16) of the airfoil. The rigid portion of the caul plate component provides improved conformation of the airfoil skin to the leading edge of the airfoil . The caul plate component also includes a compliant portion (36) which covers and defines the shape of the trailing edge of the lower surface of the airfoil. The stiffness of the caul plate component also has a variable stiffness zone (38) which interconnects the rigid and compliant portions thereof. The use of rigid and compliant portions on the caul plate provides for a controlled conformance of the skin to the leading edge of the airfoil, while allowing the skin to accurately conform to the remainder of the airfoil in spite of variations in the dimensions of internal operating components of the airfoil.

Abstract: L'invention concerne un faisceau focalisé (22) ou une unité de balayage (42) mobile dans l'espace qui est fixée à un bras mobile horizontal (27). Ce bras est fixé à un support (26) pour que l'unité de balayage puisse être déplacée d'une manière contrôlée dans un plan vertical-horizontal qui est parallèle à  une extrémité d'une pièce de bois (10). Des supports séparés (26) sont placés à l'une des extrémités de l'unité (10). Pendant son mouvement automatique et dirigé, l'unité de balayage émet un faisceau focalisé (38) et/ou reçoit des faisceaux d'énergie (38 et 48) qui ont été réfléchis par l'extrémité de l'unité (10). Ces faisceaux réfléchis dépendent de la configuration de surface de l'unité (10) et ils sont entrés dans le processeur topologique (22b ou 42b) qui traduit cette information en caractéristiques géométriques, c'est-à-dire épaisseur, largeur et longueur. Le nombre exact de pièces distinctes de bois ayant des caractéristiques géométriques particulières est alors transmis à  l'ordinateur de comptage (28). L'ordinateur (28) peut accepter des informations annexes par l'intermédiaire d'un clavier (33) ou d'un lecteur (34) de codes à barres. Le comptage de l'unité et les informations annexes peuvent être transmis au moyen d'une liaison de communication bidirectionnelle (36) à un système d'ordinateur associé qui, à son tour, peut transmettre un numéro d'identification associé, à attribuer à l'unité (10).
