Title: Unsaturated ethylene - non conjugated diene copolymers and preparation thereof by radical polymerization
Inventor: GUSTAFSSON BILL
IPC: H01B3/44
Filed: 1992-07-01
Granted: 1998-01-27
Abstract: The invention concerns an unsaturated ethylene copolymer, a method for producing the ethylene copolymer, and the use of the ethylene copolymer in compositions for producing cross-linked structures, such as material for electric cables. In the method, ethylene and at least one monomer which is copolymerisable with ethylene and includes a polyunsaturated comonomer having a chain of at least 8 carbon atoms and at least 2 non-conjugated double bonds, of which at least one is terminal, are polymerised at a pressure of about 100-300 MPa and a temperature of about 80-300.degree.C under the action of a radical initiator. The polyunsaturated comonomer preferably is an .alpha.,.omega.-alkadiene having 8-16 carbon atoms, most preferred 1,9-decadiene. Apart from the polyunsaturated comonomer, polymerisation may also involve another vinyl-unsaturated monomer, preferably containing at least one functional group selected from hydroxyl groups, alkoxy groups, carbonyl groups, carboxyl groups and ester groups. The ethylene copolymers produced have an increased degree of unsaturation, which can be used for cross-linking the ethylene copolymer or grafting reactive groups.

Title: Olefin metathesis
Inventor: KELLY JAMES
IPC: B01J23/28
Filed: 1995-07-05
Granted: 2006-03-28
Abstract: The present invention is a process for the production of a mixed C4 olefinic stream comprising primarily isobutene and butene-1, and propylene, said process comprising subjecting a mixed olefin feedstock comprising C5 olefins and ethylene to metathesis in the presence of a catalyst at a temperature in the range from about -20°C to 200°C and subjecting the resulting metathesis product to fractionation to recover the mixed C4 stream and propylene resulting therefrom. The production of MTBE or tertiary butyl alcohol or iso-butene sulphate from this C4 stream gives rise to substantially pure butene-1 as a by-product. This method therefore obviates the need separate butene-1 from butene-2 and conventional C4 saturated hydrocarbons as would be the case if a conventional MTBE raffinate had to be processed.

Abstract: A hemming machine for simultaneously bending a flange on a first panel into engagement with an edge portion of a second panel to form a hem, and at least partially curing an adhesive located in the hem.  The flange bending members and/or the top surface of the panel support nest of the present invention are heated using electric cartridge heaters, hot oil, or electric heating cables, for example.  During the hemming operation the nested panels are in constant direct contact with the panel support nest, and the heated flange bending members are in direct contact with the hem for approximately 3 to 6 seconds (dwell time is dependent on whether the die blocks are heated or if the die blocks are heating in conjunction with the top surface of the panel support nest), which is generally sufficient to at least partially cure the adhesive located in the hem, thereby reducing the incidence of panel shift during subsequent transfer through the manufacturing process using conveyors, racks etc.  By combining the hemming and heating/curing operation of adhesive bonded hems into a single machine and operation, significant savings in machines and assembly time are realized.
