Title: Annular front-sealing gasket assembly
Inventor: CROTTI ALDO
IPC: B62D55/088
Filed: 1986-10-27
Granted: 1991-10-01
Abstract: ABSTRACT            The gasket assembly comprises an annular gasket (20) and a coaxial thrust ring.  The central portion of the ring (20) is bounded by two faces (35) and (36) which are parallel and inclined so that the thickness of the central portion remains constant.  The face (35) meets a face (34) by way of a portion (37) forming a right angle therewith, and the face (36) meets a face (32) by way of a portion (38) forming a right angle therewith.  The contacting surface between the ring (30) and annular cavity (8) and between the gasket (20) and annular cavity (8) do not vary substantially as the degree of compression of the assembly varies; moreover, the deformation to which the ring (300 is subjected is substantially one of flexure.  This means that as the degree of compression varies, in proximity to the working position, the axial thrust transmitted by the ring (30) to the annular gasket (28) does not vary substantially.

These pockets successively travel to infeed stations for the printed products and the inserts.  Each pocket is equipped with a mechanism for opening the printed product located therein.  To reduce to a minimum the number of movable components in each pocket and to attain a faultless or proper alignment of the printed products with the inserts and which are collated together for  forming a final product, each pocket is provided with an entrainment element intended for the reception of a printed product.  This entrainment element is controllably displaceable, transverse to the direction of revolving motion of the pockets, between a first terminal position and a second terminal position.  In each pocket there is provided an opening element, such as an opening wedge, which is stationary in relation to the associated pocket.  This opening wedge opens the printed product which is entrained by the entrainment element during the course of displacement of the entrainment element from its first terminal position into its second terminal position.

Granted: 1992-07-14
Abstract: A B S T R A C T     A method for recovery of cellular proteins comprises treating host cells which contain the protein with at least one cationic anionic or zwitterionic surfactant and optionally a source of at least one polar organic solvent in an amount sufficient to effect cell lysis and protein solubilization without substantial modification to the structural break down of the protein.  The treatment solution with the polar organic solvent present is a mixture of from approximately five to seventy percent volumes/volume of the polar organic solvent and the at least one surfactant.  The solubilized protein is then separated from the resulting mixture.

Abstract: IN THE CANADIAN   PATENT & TRADEMARK OFFICE             PATENT APPLICATION   entitled:  Novel palladium-based alloys containing at least one additional element and their use in the glass industry, especially for pro-tecting components against corrosion by molten glass in the names of:  Jean Paul GUERLET                   Dan WEBER             Assignee:  Société Anonyme styled:  COMPTOIR LYON-ALEMAND                                     LOUYOT             ABSTRACT OF THE DISCLOSURE The invention relates to a novel palladium-based alloy.        This palladium-based alloy comprises at least one additional element selected from indium, bismuth, silver and copper, in an amount sufficient to impart an acceptable resistance to corrosion by molten glass, preferably being essentially equivalent to that of platinum-rhodium 10% alloys.        An alloy of this type can be used in the glass industry for making components which come into contact with molten glass, which preferably essentially contains no oxides less stable than the oxide of the additional element, such as lead oxide, because it has an excellent resistance to corrosion by molten glass and is less expensive than the platinum-rhodium 10% alloy normally used.  Moreover, by the addition of at least one element selected from platinum (0-50% by weight), rhodium (O-20% by weight), iridium (0-20% by weight), ruthenium (0-20% by weight) and tin (0-20%), the mechanical strength at high temperature, especially the creep strength, is significantly improved.

Abstract: ABSTRACT OF THE DISCLOSURE            Separation of hydrocarbon vapors from an admixture of hydrocarbon gases and hydrocarbon liquid is achieved by passing the admixture into the upper portion of a vapor recovery zone comprising a vertical, elongated separation zone, withdrawing hydrocarbon gases from an upper portion of the separation zone, the admixture being introduced into the vapor separation zone below the point at which the hydrocarbon gases are withdrawn from said separation zone.           The liquid introduced into the separation zone flows in a generally downward, vertical direction to a point in the lower portion of the vapor recovery zone, changing direction and flowing in an upward, substantially vertical direction forming a column of liquid.  The liquid is passed from the vertical liquid column to an oil retaining zone having an upper, gaseous zone and a lower liquid zone.  The vertical liquid column maintains a seal between the gaseous zone of the oil retaining zone and the gas-containing upper portion of the separation zone.
