The invention relates to a method of welding and assembling a component, where two or more parts of pre-insulated pipes (1) are welded together to form components of two or three parts. The pre-insulated pipes (1) consist of an outer casing (2), an inner casing (3) and an intermediate insulation (4). The outer casing (3) during the process is beveled, the insulation (4) is cleared and thermal welding is carried out with the corresponding part of another pipe. After the resulting component has cooled, the gap between the outer casings (2) thereof is filled with polymer resin.

A bonded body formed by a vibration welding of a first member and a second member. The first member includes a first base portion extending along an edge on the second member side, and a first welded portion which protrudes from the first base portion toward the second member. The second member includes a second base portion extending along an edge on the first member side and disposed to face the first base portion, and a second welded portion protruding from the second base portion toward the first member side, and a distal end of which is vibration welded to the distal end of the first welded portion. The first member has a rib for covering the first welded portion and the second welded portion from the side, and the rib is formed so as to protrude from the first base portion toward the second member side at a position separated from the first welded portion.

A bonded body is formed of a first member and a second member. The first member has a first base portion and a first welded portion which protrudes from the first base portion toward the second member side. The second member has a second base portion and a second welded portion which protrudes from the second base portion toward the first member side. In a first region of the joint portion, a first rib formed so as to project from the first base portion toward the second member side covers the first welded portion and the second welded portion from the side. In a second region different from the first region, a second rib formed so as to project from the second base portion toward the first member side covers the first welded portion and the second welded portion from the side.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

An enclosure for an electronic device includes a housing having a wall that defines a cavity that is configured to receive an electronic assembly therein. The wall includes tongue formed at a distal end. A cover includes a top wall and a side surface extending from the top wall to form a chamber. The housing is at least partially received within the chamber and the tongue of the housing is welded to a groove positioned within the chamber. Flash from the weld is contained within the enclosure so that no weld flash is visible on the exterior surface of the enclosure.

An enclosure for an electronic device includes a housing having wall defining a cavity that is configured to receive an electronic assembly therein. The wall includes a plurality of housing steps formed in an interior surface. A cap includes a side surface extending around a perimeter of the cap with a plurality of cap steps formed in the side surface. The cap is positioned at an entrance to the cavity such that the plurality of housing steps align with the plurality of cap steps and welded in place. Flash from the weld is captured in a flash trap so that no weld flash is visible on the exterior surface of the enclosure.

An enclosure for an electronic device includes a housing having a wall defining a cavity that is configured to receive an electronic assembly therein. The wall includes a distal end having a tongue. A cap is sized to attach to the housing with a corresponding groove that is formed in a perimeter of the cap. A double shear weld joint is formed between the tongue and the groove such that flash from the weld is contained within the enclosure and is not visible on the exterior surface of the enclosure.

The invention relates to a device for setting a setting element having a first plastic material in a component having a second plastic material, comprising a rotational advancing unit, by means of which the setting element can be rotated about an axis of rotation and simultaneously an axial force acting in the direction of the axis of rotation can be applied to the setting element in order to drive the setting element into the component, a friction welding joint thereby being produced between the setting element and the component, a differential-distance measuring apparatus for measuring the differential distance between a surface of the component and a surface of the driven setting element, and a control unit for controlling the rotational advancing unit in dependence on the measured differential distance.

A handle configured to be attached to a pumice stone. The handle includes a gripping portion and a post extending from the gripping portion. The post is configured to support the pumice stone. The post includes a support member, a series of ribs spaced apart along a length of the support member, and a series of cavities defined between adjacent ribs. The cavities are configured to accommodate an adhesive for coupling the post of the handle to the pumice stone.
