Abstract: ABSTRACT HALOFUNCTIONAL MONOMERIC ADHESION PROMOTERS          AND ADHESIVE COMPOSITIONS Polymeric materials modified with about 0.1 to 10, preferably 2 to 8, percent by weight of certain halofunctional monomeric materials substantially improve adhesion between an elastomeric substrate and a metal surface by improving bonding performance at the elastomer-adhesive interface and by eliminating the need for relatively large amounts of additional adhesive components such as nitroso or carbamate compounds. A preferred embodiment of the invention involves a copolymer derived from a halobutadiene monomer and .alpha.-halo-substituted monomeric compounds wherein the .alpha.-halo-substituted compound is present in an amount from about 0.1 to 10, preferably 2 to 8, percent by weight of the copolymer. A typical halobutadiene monomer is 2,3-dichlorobutadiene-1,3, while typical .alpha.-halo-substituted compounds include .alpha.-chloroacrylonitrile, .alpha.-bromo-acrylonitrile, ethyl-.alpha.-bromoacrylate, and ethyl-.alpha.-chloroacrylate.

Patent CA-2074612-A1 (CA)
Inventor: BACHMANN WERNER
IPC: B29C63/26
Filed: 1992-07-24
Abstract: To improve the strength, resistance to leaks, and formation of tears and fissures in the inner wall of a double-wall tank, the inner wall is formed, as described in the inventor's earlier Patent 4,739,895 (Re 33,421) by a plurality of foil or sheet elements which are overlapped  at the edges, and covered by a plastic, preferably epoxy layer.  The sheet elements are preferably aluminum foils of from 0.15 to 0.3 mm, preferably 0.2 mm thickness.  The plastic layer is reinforced by a multi-ply, preferably two-ply, glass fiber fabric, which is so woven that the layers or plies of the fabric are inter-woven or interlocked.  The fabric is embedded in the plastic coating, before it is cured, for example by rolling it into the plastic coating.  To assure good fitting of the inner wall against the outer wall, a vacuum is applied in the space formed by the projections or puckers of the sheet elements and the outer wall before the plastic coating has cured, and maintained until it is cured.  The sheet or foil elements and the reinforced plastic will then form a laminate of high inherent stability with high bending and tensile strength, so that fissures are effectively avoided and the tank construction will be reliably tight and highly resistant to the formation of bulges and damage, for example due to dropped tools during installation, or inspection.

Title: Measurement of the flow velocities of gases and/or of quantities that can be derived from same
Inventor: MAEYRAENEN TARMO
IPC: G01F1/7082
Filed: 1992-11-12
Abstract: Method and device of acoustic flow measurement for measuring the flow velocity of a gas and/or of quantities that can be derived from same. Acoustic signals are transmitted into a measurement pipe. The acoustic signals passing in the gas flow downstream and upstream are detected by means of two sound detectors placed in connection with the measurement pipe a.t a specified distance from one another, the flow velocity of the gas that flows in the measurement pipe being determined by making use of polarity correlation of said signals. The frequency of the sound that is transmitted into the measurement pipe is scanned between a certain minimum and a certain maximum frequency. The measurement signals arriving from the two sound detectors are passed to a narrow-band filter or system of filters. The passband of said filters is scanned synchronously with the frequency scanning of the sound transmission. The duration of the frequency scanning and the width of the passband of said filters are chosen so that, at the moment of the measurement sequence, the measurement signal detected by each sound detector has access through its filter substantially without attenuation, as well as so that the interference frequencies substantially different from the mean frequency of the filters are attenuated significantly.
