A production line for making tangible products by layerwise manufacturing. The production line comprises: (i) a first and a second building platform for carrying a tangible product; (ii) a deposition head for providing a layer of construction material onto the building platforms; (iii) a conveyor for conveying the building platforms in a conveying plane towards and away from the deposition head repeatedly; and (iv) height adjustment means to adjust the distance between the deposition head and the building platforms by displacing the building platforms relative to the conveyor in a direction perpendicular to the conveying plane. The production line may further comprise a picking unit for picking a product from the building platforms.

A production line for making tangible products by layerwise manufacturing. The production line includes: first and second movable carriers, each carrier comprising a transporter for transporting the carrier, and a building platform for supporting a tangible product, one or more deposition heads for depositing construction material in a deposition direction onto the building platforms, and a conveyor for conveying the first and second building platform towards the deposition head and away from the deposition head repeatedly. The first and the second transporter are movable at variable speeds relative to each other along a trajectory of the conveyor. Optionally, the height of the building platforms can be adjusted.

A method of fabricating a part includes: a) supplying powder particles; b) melting a first quantity of power with a beam and forming, on a support, a first pool including the melted powder and a portion of the support; c) forming a second pool by melting a second quantity of powder on the support; d) repeating c) to form a first layer; e) heating an [n].sup.th quantity of the powder, and forming an [n].sup.th pool above the first layer; f) heating an [n+1].sup.th quantity of the powder, and forming an [n+1].sup.th pool downstream from the [n].sup.th pool above the first layer; g) repeating f) to form a second layer above the first layer; and h) repeating e) to g) until the part is constructed. The powder particles reaching each pool are at a temperature well below the pool temperature.

Certain polyamide beads or granules are useful as a sustaining material for underground natural or artificial cracks of the earth's crust essentially employed for the extraction of hydrocarbons such as crude oil or natural gas; such polyamide beads have a spherical or ellipsoidal shape and have a surface free of concave portions, advantageously having a uniform shape, and having a mean diameter lower than or equal to 1.7 mm and a porosity lower than 0.1 ml/g, and are produced using a particular cutting device/extruder.

Provided is a melt-molding material which is produced using an EVOH resin and has improved feeding property. A pellet mixture comprising a first EVOH resin pellets (pellet 1) each having approximately circular or elliptical cross-section and having an ethylene unit content of 20 to 34 mol %, and a second EVOH resin pellets (pellet 2) each having ethylene unit content of 35 to 60 mol %, wherein the difference of ethylene unit content between the pellet 1 and the pellet 2 is from 10 to 30 mol %.

The present invention relates to a nozzle for cleaning a substrate capable of spraying deionized water for cleaning a substrate to the substrate, the nozzle including a first body made of a resin material and provided with a first part of a deionized water passage and a deionized water supply hole to supply the deionized water, a second body made of a resin material and provided with a second part of the deionized water passage and a plurality of spray holes to spray the deionized water to the substrate, a fusible protrusion provided in the first body or the second body along the deionized water passage and configured such that a part thereof is fused during ultrasonic welding, so as to couple the first body and the second body together, and a fusible protrusion accommodating part formed in the first body or the second body to accommodate the fusible protrusion.

An electric ice press is provided herein and may be utilized to reshape an initial ice billet into a sculpted ice nugget. The electric ice press may include a mold body having a first mold segment and a second mold segment movable relative to each other. A guide rail extends from the first mold segment for receipt in a sleeve defined by the second mold segment to align the first mold segment and the second mold segment. A resilient bumper is mounted on the distal end of the guide rail to prevent marking or scratching the second mold segment.

A method of manufacturing an article comprises rotomolding at least one polymer comprising a poly(aryl ketone), such as PEKK, under conditions effective to produce a rotomolded article having an impact value of at least 35 in-lbs. A rotomolding method comprises heating the mold for a period of time after the internal air temperature of the mold reaches the highest melting point of the at least one polymer. Methods also include using a PEKK powder with a bulk density of at least about 400 g/L. Rotomolded articles of the present invention have impact values of between about 40 in-lbs to about 95 in-lbs, and in particular embodiments greater than about 95 in-lbs.

The invention relates to a workpiece having a shape produced by thermoforming from at least one sheet (3) of plastic material, such as polycarbonate, and at least one applied element (6, 8; 7, 9) that is applied to the at least one sheet and secured there, characterised in that the securing of the at least one applied element to the at least one sheet takes place at least partially by means of crimping.

An apparatus for compacting waste objects includes a seat provided with a support assembly for supporting the waste object to be compacted; a push member being moveable inside the seat for compacting in use of the apparatus the waste object against an end wall of the seat; the support assembly including two support members that rotate away from each other for discharging the compacted object through an aperture. The support members can impede discharge of a compacted object of a specific type through the aperture to collect the compacted object of the specific type in a dedicated container. Protuberances can be applied to the push member and an end wall of the seat for producing depressions in the compacted object so that the compacted object does not lose the compacted condition once pressure applied by the push member is removed.
