Patent CA-2261952-A1 (CA)
Title: Improved paint spray booth
Inventor: ALLMAN JOHN
IPC: B05B15/12
Filed: 1997-07-29
Abstract: A paint spray booth for painting an article and separating the spent paint overspray from the air and water used in the booth to collect the spent paint material is disclosed. The booth includes a water containing pan which has a deep portion and a shallow drain portion. The water used to separate the spent paint from the air and to clean the air discharged from the booth is collected on the drain portion and sent to the deep portion of the pan in a manner to cause a flow in the drain portion and deep portion of the pan to prevent accumulation of spent paint in undesired, inaccessible locations and to encourage movement of spent paint to desired, accessible locations in the pan and/or for removal or further treatment as by settling, skimming and/or separating, or the like, to provide the present invention with low maintenance similar to or less than other such booths, such as dry filter paint spray booths. The booth has a water manifold in its eliminator-washer section with a plurality of openings therein covered by a space "v" shaped cap which is easily cleaned and kept clean. The booth, preferably, has a spent paint intake pipe with a plurality of slots therein extending across and submerged below the surface of the tank to draw off the spent paint containing water, some of which is recirculated to the tank, some of which is recirculated in the washer section of the booth, and some of which is sent to be concentrated and remove the spent paint material.

Title: Pharmaceutical aerosol composition
Inventor: BRAMBILLA GAETANO
IPC: A61K47/06
Filed: 1998-06-10
Abstract: A composition for use in an aerosol inhaler comprises an active material, a propellant containing a hydrofluoroalkane and a cosolvent.  The composition further includes a low volatility component which is added to increase the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler.

Patent CA-2265706-A1 (CA)
Title: Connector plate and punch for forming
Inventor: LEES WILLIAM F
IPC: F16B15/00
Filed: 1997-09-15
Abstract: The connector plate (100) Bias a rigid, planar base ( 10 2), and a plurality of adjacent elongated slots (l08) defined in said metal plate (100). The slots (l08) are offset in a sinusoidal pattern having at least one cycle with a maximum amplitude slot position, a minimum amplitude slot position and at least two zero-point slot positions. Each slot (108) has first and second reverse-oriented mirror-image teeth (104, 106) extending from the plate (100) at opposing ends of each slot f 108). A punch ( 302) having a base portion (308) having a longitudinal axis (310) and a shank (304) having a longitudinal axis (306) offset from the base portion longitudinal (310) axis is also provided. 1n producing the connector plates of the present invention, the sheet metal material, or connector material, from which the connector plate is to be formed is incrementally passed between a series of punches and corresponding dies. The punches and dies are arranged so that each punch will strike the metal material and pass through so as to extend into a cavity of a corresponding die. When the punch extends into the cavity of the dies, a substantial portion of the space between longitudinal side edges of each punch and corresponding die is less than the thickness of the sheet material. Thus, as the punch enters into the cavity of the die material forming occurs whereby the teeth are reshaped by wiping the metal between the side walls of the punch and the die cavity. In this manner, the offset spines (110) of the teeth are formed set from the longitudinal axis S of the slots (108). As the punch is fully extended into the die cavity, each tooth is forced into a position substantially vertically aligned with its opposing tooth.

Patent CA-2271003-A1 (CA)
Inventor: MERCER FRANK W
IPC: C08L101/00
Filed: 1997-10-28
Abstract: L'invention porte sur une composition (1) à forte conductivité thermique mais néanmoins très malléable consistant en un gel chargé d'alumine. En utilisant de l'alumine .alpha. dans laquelle au moins 10 % en poids des particules d'alumine .alpha. ont une taille d'au moins 74 µm, on atteint les niveaux élevés de charge requis pour obtenir une forte conductivité thermique, sans occasionner les diminutions d'allongement et de souplesse qui accompagnent habituellement les niveaux élevés de charge. D'autres améliorations apparaissent lorsque l'alumine .alpha. et le gel (ou son précurseur) sont mélangés avec un apport spécifique d'énergie d'au moins 10 Joule/g. Cet apport d'énergie rend la composition résultante plus malléable qu'elle le serait sinon. La composition peut recevoir un support interne consistant en une matrice souple par exemple de mousse (2) à cellules ouvertes, ou de toile (3).

Title: Use of silicone compositions cross-linkable by cationic process under uv radiation and of an onium borate type photoinitiator for coating flat joints, particularly cylinder head gaskets
Inventor: COTTING MARIE-CHRISTINE
IPC: C09K3/10
Filed: 1997-12-29
Abstract: The invention concerns the use of cross-linkable silicone compositions for fast, economical and simple impregnation and/or varnishing of flat joints (e.g. cylinder head gaskets). More precisely it concerns the use of silicone compositions cross-linkable under UV radiation, by cationic process, and in the presence of specific photoinitiators selected among onium borates or organometallic complexes, of which the borate counter-anions contain at least a boron bound to at least a substituted phenyl (Me, F). The silicone liquid precursor is a polydimethylsiloxane (PDMS) substituted by cross-linking functional groups, by cationic process (G¿fp?) under UV of the epoxy or vinyloxy type. These G¿fp? are present at the rate of 0.15 to 2.0 pr kg of PDMS. The invention also concerns the method for impregnating/varnishing flat joints (e.g. cylinder head gaskets) using the specific PDMS composition + photoinitiator of borate type as well as the treated joints and the composition themselves.

Title: Compressed nitroglycerin tablet and its method of manufacture
Inventor: CAPELLA ROBERTO L
IPC: A61K9/10
Filed: 1998-09-16
Abstract: The present invention is directed to a stable nitroglycerin containing pharmaceutical composition, preferably a tablet which is prepared by direct compression technology. The formulation closely replicates the properties of nitroglycerin molded sublingual tablets (e.g. adequate disintegration and sublingual absorption), while reducing the problems experienced with compressed tablets (e.g. friability and weight variations). The stable tablets are characterized by a decreased migration of nitroglycerin, decreased potency loss, excellent content uniformity when stored. The preferred combination of components are: nitroglycerin/lactose dilution, hydrous lactose, glyceril monostearate, fumed silica, pregelatinized starch and calcium stearate. The preferred process employs direct compression technology to yield composition showing adequate disintegration, bioavailability and improved stability.
