Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

Methods for installing an advertising unit at an installation area of a surface are provided. The installation area is cleaned. One or more holes are formed in the installation area. The adhesive is applied at the installation area. The advertising unit is deposited at the installation area atop the adhesive. A fastener is passed through at least a portion of the advertising unit into each of the one or more holes. The adhesive is cured.

Systems for positioning and bonding a nutplate to a substrate having an aperture include a nutplate engagement fixture and a temperature sensor retention fixture. The nutplate engagement fixture includes a rigid tube and an elastomeric tube engaged with the rigid tube, the elastomeric tube having an elongated tube sized to provide a friction fit with the aperture and retain the elastomeric tube within the aperture. The rigid tube is operable to engage the nutplate at one end and the elastomeric tube is configured to anchor the nutplate engagement fixture at the aperture and secure the nutplate in contact with the substrate. The temperature sensor retention fixture includes a fixture body sized and configured to engage with the nutplate and at least one passageway within the fixture body sized and configured to allow a temperature sensor to be inserted or embedded therein with an end proximal a surface of the nutplate.

Embodiments are directed to nozzles for three-dimensional printing and related nozzle assemblies and methods. An example nozzle includes at least one top surface, at least one bottom surface, and at least one nozzle lateral surface extending from or near the top surface to or near the bottom surface. The nozzle also includes at least one conduit surface defining a conduit. At least a portion of the conduit surface comprise at least one of polycrystalline diamond (“PCD”), polycrystalline cubic boron nitride (“PcBN”), or another suitable superhard material. The nozzle may be attached to a base to form a nozzle assembly. The nozzle may be attached to the base by at least one of deforming the base relative to the nozzle, threadedly attaching (either directly or indirectly) the nozzle to the base, or press-fitting a hollow hollowed-sleeve into a passageway defined by the base.

A display module is disclosed. The display module includes a planar display area and a curved display area bending and extending from an edge of the planar display area. The display module includes a curved cover plate, a flexible display panel attached to the curved cover plate, and a backplate. The backplate includes a thinning part, and a thickness of the thinning part is gradually reduced from an edge area of the planar display area to the curved display area. The present disclosure can reduce forces undergone by the flexible display panel in the curved display area and prevent curved sides of the flexible display panel from having a cracking risk.

An automatic splicing apparatus and methods thereof are provided herein for splicing together two ends of a sheet of tire material on a tire building drum. The apparatus comprises a frame, a splicer foot assembly, and a splicer roller assembly. The frame is configured to support the apparatus relative to the drum. The splicer foot assembly and the splicer roller assembly are independently longitudinally translatable relative to the frame. The splicer foot assembly includes a splicer foot having forward lower preparation rollers and rearward lower splicer rollers, and upper preparation rollers configured to operate in coordination with the forward lower preparation rollers to pull the two ends of the sheet of tire material together over the splicer foot. The splicer roller assembly includes upper splicer rollers configured to act in coordination with the rearward lower splicer rollers to splice the two ends together.

Discussed is a battery pack case configured to receive a plurality of battery cells, the battery pack case including a first case and a second case coupled to each other through and engagement between first case and the second case. A projecting portion is on a coupling portion of the first case at a middle part of the first case in a thickness direction to project therefrom, a grooved portion is in a coupling portion of the second case at a middle part of the second case in a thickness direction thereof such that the projecting portion is inserted into the grooved portion, and a uniform gap between the outside of the projecting portion of the first case and the outside of the grooved portion of the second case in the state in which the first case and the second case are coupled and thermally fused to each other.

A cable tray of the ladder type configuration can be fabricated from soft solid curable polymer strips comprised of a thermosetting material. The curable polymer strips in a pliable state may be wound into strip rolls for storage and transportation to the installation site. At the installation site, the soft solid curable polymer strips can be deployed, molded into pliable formed rail sections, and transversely connected together by a plurality of rungs. The curing process can be completed by, for example, exposing the thermosetting material to a ultraviolet or visible light source to produce hardened rail sections of the ladder type cable tray.

A connector assembly for connection of two tubular members without rotation. The assembly includes the pin end of a first tubular member stabbed within the connector end of a second tubular member. A connector nut is threadedly connected or snap locked to the connector end of the second tubular member. The connector nut includes a retaining shoulder cooperating with a beveled shoulder on the pin end of the first tubular member to retain the first tubular member. The assembly includes seals to provide pressure integrity and prevent leaking. Cooperating rotational torque transfer profiles in the first and second tubular members enable operational rotation of the tubular string.
