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.

Disclosed is a method for making a decorative groove between joint edges on a laminate floorboard. The floorboard includes an upper layer and an underlying layer. The method involves fixing the floorboard between at least one chain and at least one band, displacing the floorboard relative to a milling machine, and removing at least a part of the upper layer, so that a surface of the underlying layer is uncovered, by a tool that performs machining between the at least one chain. The surface of the underlying layer defines at least a portion of a visible width of the decorative groove.

An additively manufactured component is provided. The additively manufactured component includes an additively manufactured first part defining a first trench, an additively manufactured second part defining a second trench and a fiber optic sensor. The additively manufactured first and second parts are additively manufactured together with the first and second trenches corresponding in position such that the additively manufactured first and second parts form an assembled part with a fiber channel cooperatively defined by the first and second trenches. The fiber optic sensor includes a first sensor part embedded in the fiber channel and a second sensor part operably coupled to the first sensor part and extendible at an exterior of the assembled part.

A hybrid torque bar for a brake assembly may comprise a base portion, a pin extending from a first end of the base portion, and a rail extending between the first end of the base portion and a second end of the base portion opposite the first end. The base portion may be formed using a first manufacturing process. At least one of the pin or the rail may formed using a second manufacturing process. The second manufacturing process may comprise an additive manufacturing technique.

There is disclosed a member for sealing, baffling and/or reinforcing components of an automotive vehicle. The assembly generally includes a carrier, an expandable material and at least one fastener.

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.

The method includes forming an inner monolithic layer from crystals of beta phase stoichiometric silicon carbide on a carbon substrate in the form of a rod by chemical methylsilane vapor deposition in a sealed tubular hot-wall CVD reactor. The method further includes forming a central composite layer over the inner monolithic layer by twisting continuous beta phase stoichiometric silicon carbide fibers into tows, transporting the tows to a braiding machine, and forming a reinforcing thread framework. A pyrocarbon interface coating is built up by chemical methane vapor deposition in a sealed tubular hot-wall CVD reactor. Then, a matrix is formed by chemical methylsilane vapor deposition in the reactor. A protective outer monolithic layer is formed from crystals of beta phase stoichiometric silicon carbide over the central composite layer by chemical methylsilane vapor deposition in a CVD reactor. And then the carbon substrate is removed from the fabricated semi-finished product.

A method for manufacturing an angle-type air tool housing is provided. The angle-type air tool housing includes a hollow tube having a first end and a second end that are open and are mutually in communication, and an overall housing formed by injection molding and enveloping the hollow tube, and having an accommodating chamber adjacent to the first end, an air channel adjacent to the second end and in communication with the accommodating chamber through the hollow tube, and a pair of recesses exposing a part of the hollow tube. Accordingly, the angle-type air tool housing that is a formed integral with the hollow tube is formed so as to achieve effects of reduced costs and weight.

A package for securing a card is disclosed where the card is retained between two panels that are secured together by a heat-activated adhesives and/or a combination of polymeric and adhesive constituents to drastically hinder surreptitious access to the contents of the package. The package may include additional features for activating or accessing the card and increasing the aesthetic appeal of the package.

A method of manufacturing a surgical device can include generating a first internal frame defining an internal structure of an instrument tip; covering at least a portion of the first internal frame with a first coating to define an exterior surface of the instrument tip; and generating an instrument body such that a proximal end of the instrument tip is positioned at a distal end of the instrument body. An ophthalmic surgical instrument can include an instrument body; and an instrument tip disposed at a distal end of the instrument body, the instrument tip including a first section linearly extending along a longitudinal axis of the instrument body and a second section extending obliquely from the first section, the second section being arcuately shaped; and wherein the instrument tip comprises a first internal frame and a first coating covering the first internal frame.
