Such resins exhibit surprising and previously unattained combination of superior physical properties. Articles made with such composites are disclosed.
Abstract:
A non-aqueous mixed solvent for use in a non-aqueous electrolytic solution for electrochemical energy devices which can enhance the high current charging and discharging capacity and low-temperature charging and discharging capacity of an electrochemical energy device, and prevent the device from damage at high temperatures. The solvent comprises an aprotic solvent and at least one fluorinated ether having a boiling point of 80°C or more and being represented by R 1 -O-R f1 (formula 1), R 2 -O-(R f2 -O) n -R 3 (formula 2) or R fh1 -O-A-O-R fh2 (formula 3). Also electrolytic solutions comprising such solvents and electrochemical energy devices containing such electrolytic solutions.
Abstract:
A film (50) processing apparatus (20) including a film stretching device (22) and a take-away device (24). The take-away device receives the film after the stretching device and transports the film along a conveying region in a direction of transport (X). The take-away device includes opposing, first and second conveyor assemblies. The first conveyor assembly has a continuous belt driving a plurality of discrete pads (180a, 180b). Each pad forms a contact face (194a, 194b) extending between leading (200b) and trailing edges (202a). The pads are configured and arranged such that the trailing edge (202a) of a first pad (180a) overlaps the leading edge (200b) of an immediately adjacent second pad (180b) as the first and second pads traverse the conveying region. The overlap is characterised by a line (322) perpendicular to the direction of transport passing at any given moment through the first and second pads. A shape of the contact face can define a major central axis that is non-perpendicular and non-parallel with the direction of transport. The invention also relates to a method of processing a film using such an apparatus.
Abstract:
A center-fed single cavity slot die (100) for coating particulate suspensions without creating the coating defect known as center banding. The die has a flow obstruction device (109) located in the die cavity (105) in a position such that the flow obstruction device blocks undisturbed straight-line flow of coating composition from the feed inlet to the die coating slot. Also, a coating process that employs the disclosed coating die. Types, shapes, sizes, and compositions of particles that may be used, and viscosities and particle concentrations of the coating composition which may be used.
Abstract:
A method for conveying a workpiece having a first major surface with exposed adhesive using at least one transport roll (34) having an engagement cover (24) having an engagement surface comprising looped filaments (26) that have a low surface energy wherein the workpiece (10) passes through engaging contact with the engagement surface such that at least a portion of the pressure sensitive adhesive(18) directly contacts the engagement surface wherein the pressure sensitive adhesive (18) is tacky when in contact with the engagement surface. Also an apparatus for carrying out the method.
Abstract:
Self-laminating protectors comprising: (a) a first sheet (12); (b) pressure sensitive adhesive (18) covering at least a portion of a side of the first sheet (12); (c) a release member (20) releasably adhered to a portion of the adhesive, the release member (20) having a first segment (22) and a second segment (24), the protector being adapted such that the first segment (22) can be readily gripped by hand at a location proximate to the second segment (24); and (d) a second sheet (26), wherein the first and second sheets (12) are conjoined and the first segment (22) of the release member (20) is located closer to where the first and second sheets (12,26) are conjoined than is the second segment. Also, a method of using such protectors.
Abstract:
A label assembly from which labels can be readily removed, the assembly comprising a carrier sheet having a front major surface and a back major surface and a label stock sheet removably attached to the front major surface of the carrier sheet, wherein (a) the carrier sheet is configured in two or more segments comprising at least one liner segment and one or more carrier strip segments, (b) the label stock sheet is configured in one or more segments comprising one or more labels and one or more strips or frames, and (c) the carrier strip segment overlaps the edge of one or more labels.
