A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The rotary pump includes a plunger and optional stopper formed from a two-shot molding process, and including seals overmolded onto the head of the plunger and the head of the optional stopper.

Methods of fabricating a manhole insert gasket on a manhole insert flange of a manhole insert may include inverting a manhole insert having a manhole insert flange; forming a manhole insert gasket by dispensing a liquid gasket material onto the manhole insert flange along at least one circular dispensing path, the liquid gasket material including a synthetic silicone elastomer; and curing the gasket material.

Floorboards which have a core and a surface layer and are provided with decorative joint edges which are formed by removing the surface layer. A method for making a floorboard, or a floor element that is to be divided into at least two floorboards, the method including making a core from a sheet shaped material, from which a part of a locking system for vertical locking of the floorboards is to be formed, impregnating and/or staining the core surface with a substance at least in portions which in the completed floorboard will constitute a joint edge of the completed floorboard, and arranging an surface layer on the core surface.

A process for manufacturing a turbomachine part coated with a thermal barrier, includes manufacturing the part by additive manufacture; electrophoretic depositing the part of a layer including particles of a ceramic material; consolidating the layer by heat treatment to obtain a ceramic coating.

Methods of forming topographical features on an article, for example on a medical devices that has a surface configured to promote the migration of cells onto the surface of the medical device. In particular, the resulting surface of the medical device has a noncontiguous pattern of topographical features formed therein or thereon.

A tool bit includes a hexagonal drive portion, a working end, and a shank interconnecting the drive portion and the working end. The shank includes an outer peripheral surface having a curvature in a plane including a central axis of the tool bit. The outer peripheral surface having the curvature includes a length in the direction of the central axis. A ratio of the length of the outer peripheral surface having the curvature to the length of the tool bit is between about 0.2:1 and about 0.7:1.

A method for forming a bicycle frame assembly having a number of elongate tubes is disclosed. A two part mold can be used to form a hollow finish part as part of the assembly. The assembly includes a passage that is defined by the elongate member, a partition, and a bridge. The partition isolates the passage from an interior volume of the elongate tube. The bridge extends in a direction normal to an elongate direction of the passage and defines an inlet and an outlet of the passage. The inlet, outlet, and bridge are generally flush with an exterior surface of the elongate tube and provide a passage that cooperates with a flexible connector, such as a cable tie, for securing supplemental structures, such as brake and shift control cables, to the elongate tube of the bicycle frame assembly.

A method of mounting a roof panel assembly to a vehicle having a roof opening in its fixed roof includes: mounting a frame of the roof panel assembly to the fixed roof from below with an operating mechanism and a ring frame in a position corresponding to a closed position of the movable panel, providing an amount of paste-like adhering material onto the ring frame distributed around the circumference thereof, positioning the movable panel onto the ring frame from above with the adhering material interpositioned and compressing the adhering material until a correct position with respect to the vehicle roof is reached, and keeping the movable panel in this position until the adhering material is sufficiently hardened to maintain the panel in its position.

A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.

This invention describes Ophthalmic Devices with media inserts that have nanostructured Metasurface elements upon or within them. In some embodiments passive ophthalmic devices of various kinds may be formed. Methods and devices for active ophthalmic devices based on Metasurface structures may also be formed.
