IPC: F28D7/00
Filed: 1985-05-28
Abstract: A transfer-line exchanger is disclosed having two separate heat exchanging zones (20,30) or compartments. Specifically, the transfer-line exchanger is comprised of a tube or tubes (24) through which the hot gas (61) being cooled is flowed. Each tube (24) is contained in a larger, outer tube or a number of tubes contained in the shell (21). Each outer tube or the shell (21) is divided into two compartments or zones (20,30) through which the cooling medium is flowed. The compartments or zones (27,37) in the outer tubes or shell are designed such that the hot gas flowing through the tube or tubes (24) is sequentially cooled by a cooling medium flowing through the first compartment (27) at a first temperature and a cooling medium flowing through a second compartment or zone (37) at a second and generally lower temperature. The tubes of the two sections are connected by intermediate tubes (24C) loosely held in guide sleeves (11,12) on the ends of the two sections. Although the transfer-line exchangers of the present invention are described with reference to two heat exchanging zones or compartments, additional cooling by means of additional compartments or zones can be affected.

Title: Lamination anchoring method and apparatus and product thereof
Inventor: LARSONNEUR LIONEL M
IPC: B32B7/08
Filed: 1987-04-08
Abstract: Conventionally absorbent sheets for meat packaging are made of absorbent cellulose laminations 18 with a cover sheet 14 of polyethylene. The laminations are compression bonded by means of a serrated wheel which forms a series of indentations along one or more lines. When moisture is absorbed the sheet 14 tends to delaminate. To prevent this a thermo-setting material such as a wax is applied along the line of indentations. A wax rivet 24 is thus formed which provides additional mechanical bonding and prevents access of moisture to the immediate region of the compression bond 22 by reason of the absorbed wax 24A.

Filed: 1991-01-16
Abstract: There is disclosed a linear block copolymer comprising at least one triblock I-B-I, wherein I is a block of a polymerized conjugated diene of at least 5 carbon atoms, such as isoprene, and B is a block of a polymer of a conjugated diene, different from that of formula (1), of at least 4 carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from an aryl-substituted olefin, such as styrene, and the conjugated diene used to polymerize the block I, the second middle polymer block of the diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of double bonds to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal blocks containing the vinyl unsaturation. There are also disclosed random and star-branched block and random copolymers made from the same monomers as the linear block copolymers.

Title: Nondestructive method and device for the determination of element composition of samples containing light elements
Inventor: UZUNOV NIKOLAJ M
IPC: G01N23/08
Filed: 1997-02-12
Abstract: The method and the device are used for the analysis ofsamples containing light elements and those in the beginning ofthe periodic system or chemical compounds including elements inthe beginning of the periodic system, such as hydrogen, carbon,nitrogen, oxygen, and others. They help discovering elements thepresence of which has not been known in the sample in advance. Themethod can be applied for a wide class of tested sites where thequantity of the prospected chemical elements is not under 1% forthe hydrogen and several tenths of a percent for the heaviermetals. There are no requirements about the aggregate condition ofthe sample. The relation of the degree of reducing of a low energygamma radiation from a radioactive source can be tested fordifferent values of its energy in the tested sample. The degree ofirradiation absorption in the sample opens the opportunity forforming a system of linear algebraic equations about the unknownquantitites of the chemical elements in it.2 claims, 4 figures
