A method for producing laminated glass for automobile windows includes:

heating and bend forming two glass plates; and

bonding together the two bend-formed glass plates via an interlayer film, wherein before the heating and bend forming of the two glass plates, at least one glass plate of the two glass plates that are flat, is conveyed by a conveying unit while either a conveying unit-facing surface of the at least one glass plate or a non-facing surface of the at least one glass plate that is opposite to the conveying unit-facing surface is scratched by the conveying unit, and

in the bonding together of the two bend-formed glass plates via the interlayer film, the scratched surface is disposed such that the scratched surface is situated on a vehicle-interior side upon the laminated glass for automobile windows being attached to an automobile.

The invention relates to use of selected materials in systems for heat treatment, various forms of such material, related systems and methods for determining such materials. In particular the invention relates to the use of a cover of analumina-chromium alloy material with a Cr content of more than 5 w % (percent by weight) for one or more parts within a system suited for heat treatment.

A method for making a heat-resistant roll includes pre-selecting a plurality of heat-resistant disks and pressing at least a selected portion of the pre-selected disks together such that a total axial thickness of the pressed disks relative to a total axial thickness of the selected disks prior to pressing is within a predetermined range.

An end cap assembly for a conveyor roll includes an end cap configured to fit over an end of the conveyor roll, and the end cap has an opening. The end cap assembly further includes a spring member configured to be positioned between the end of the conveyor roll and the end cap, and a fastener that is insertable into the opening of the end cap. The fastener is configured to cooperate with the spring member to apply a retention force to assist in retaining the end cap on the conveyor roll.

A base material for a disk roll containing a layered silicate, in which the layered silicate is constituted to contain two or more kinds of minerals having an interlayer distance exceeding 10 angstroms. A base material for a disk roll is excellent in the compressive strength and wear resistance thereby.

A conveyance device for glass sheets advancing them one after the other, includes at least one roller including a glass sheet conveyance area, the device including actuators located on either side of the conveyance area capable of bending the roller within its elastic deformation domain while leaving it able to be driven in rotation around fixed centers of its sections, wherein the roller includes a shaft and a plurality of bending rings into which the shaft is inserted.

A lift-up roller arrangement for electronic float glass, including a plurality of lift-up rollers rotatably arranged on the inner wall of an annealing kiln, wherein a plurality of boron nitride rings are fixedly sleeved on the outer side wall of each lift-up roller; a heat-resisting steel tubes is arranged on each of both sides of each lift-up roller; a plurality of exhaust holes are arranged on an outer side wall of the heat-resisting steel tube; the heat-resisting steel tube is in communication with an external hot gas supply case; and a plurality of cleaning assemblies used in cooperation with the lift-up rollers are arranged at the inner bottom of the annealing kiln.

An integral metal end cap for use in a conveyor roll assembly is suitable for use in an environment subject to significant temperature variation. The metal end cap comprises a first end connectable to rotary means, and a second end comprising an integral body adapted to fit over the end of a ceramic spool. The integral body contains a torque transmission portion having a plurality of deformable strips enabling transmission of torque during temperature variations. A conveyor roll assembly comprises a ceramic spool having a longitudinal axis and, at least at one end of the ceramic spool, a metal end cap as described.

A conveyor roll assembly for use at high temperature comprises (a) a ceramic spool having a flexural strength of at least 15 MPa and an external diameter D and (b) a torque transmitter and support of a general cylindrical shape and having a longitudinal axis, comprising a body and (b1) a supporting portion comprising at least one cylindrical supporting surface and (b2) a connecting portion that is mechanically and resiliently deformed, comprising at least two distinct connecting surfaces, frictionally connecting the torque transmitter and support to the ceramic spool. At least one end of the ceramic spool has an axial, centered bore of a diameter 10 mmd D, and a depth Dd1.5 d. The torque transmitter and support is housed at least partially in the bore of the ceramic spool.
