The invention relates to a method and guide system for the transport of containers or container components, in particular, preforms and/or closure caps, in industrial systems for container production and/or product filling, wherein the containers/container components are transported along at least one guide element. By generating an air cushion between the guide element and the containers/container components by flowing through a microporous layer formed on the guide element, even container components which are lightweight and/or do not slide well can be reliably slidingly transported along the guide elements, and containers can be reliably supplied to dividing worms or similar using dynamic pressure.

Disclosed is a method for manufacturing a fiber composite member. The method involves the step of producing a fiber layer by depositing at least two fiber webs in a plane adjacent to each other and along a circular guiding arc. The fiber webs are deposited on curved deposition paths that intersect the circular guiding arc with the same predetermined angle, and are formed in the form of portions of circular involutes.

The tray (20) comprises a plurality of plates (60) and a frame (25) supporting the plates (60). The frame (25) is configured to be stacked vertically with a plurality of identical frames to form a tray stack (10). Each plate (60) is a carbon-fiber reinforced polymer plate and comprises a plurality of support structures (110) each arranged to support one contact lens mold assembly (70) during curing and a plurality of channels (90, 100) connecting the support structures (110), to allow gases to flow between them in the tray stack (10) during curing.

An apparatus for transporting plastics preforms, having a first transport element that extends along a transport path of the plastics preforms and having a second transport element parallel to the first transport element. The first transport element and the second transport element are spaced apart from one another such that a gap is formed between the first transport element and the second transport element such that a base body of the plastics preforms can pass through this gap, but a support ring of the plastics preforms cannot pass through this gap. The apparatus has a hold-down device that is arranged above the transport elements and/or the mouths of the plastics preforms, wherein the hold-down device has a first hold-down element movable in two opposite directions in a longitudinal direction of the plastics preforms along with a drive device configured to cause these movements during a transport operation of the apparatus.

The present invention relates to a lighting system for analyzing pellet and a foreign matter sorting apparatus comprising same. The lighting system for analyzing pellet comprises: a casing (100) which has an inner space and a through-hole (110) formed in the upper surface, and in which objects to be sorted (P), including a plurality of pellets, move across the inner upper portion and the inner lower portion; an upper lighting assembly (200) which includes a plurality of first light sources (210) each irradiating first illumination light, and a first light source holder (220) which fixes the first light sources (210) so that a row direction light source array, in which some of the first light sources (210) are arranged in the lengthwise direction of a virtual curved surface, is arranged in parallel along the arc direction of the virtual curved surface, wherein the virtual curved surface, of which the arc direction is the vertical direction, is convex toward the objects to be sorted (P), and the upper lighting assembly (200) is arranged on the inner upper portion of the casing 100 and irradiates the first illumination light toward the upper and side portions of the objects to be sorted (P); and a lower lighting assembly (300) comprising a plurality of second light sources (310) each irradiating second illumination light, and a second light source holder (320) which fixes the plurality of second light sources (310), wherein the lower lighting assembly (300) is arranged on the inner lower portion of the casing (100) and irradiates the second illumination light toward the lower and side portions of the objects to be sorted (P).

An electrical Kelvin contact assembly for testing IC testing apparatus that uses an assembly design that reduces the tolerance to a near negligible range. The assembly does not use any screws, dowel pins, adhesives or welding to fasten the electrical contacts to the housing. The design of the assembly uses rows of contacts with specially designed protrusions that sit snugly in openings located on three plate-like layers. These layers contain the contacts in the horizontal plane by securing the protrusions in the opening, as well as in the vertical plane by means of a sandwich between three separate layers. A second contact is slid into back slits formed by the three layers.

A shape measurement device and a shape measurement method according to the present invention measure, for first and second distance measurement units which are disposed so as to be opposed to each other with a measurement object to be measured interposed therebetween and each measure a distance to the measurement object, first and second displacements of the first and second distance measurement units in an opposition direction, and obtain, as a shape of the measurement object, a thickness of the measurement object in the opposition direction, the thickness being corrected with the measured first and second displacements, based on first and second distance measurement results measured by the first and second distance measurement units, respectively.

A plant for reshaping plastic preforms into plastic containers, includes a heating device for heating the plastic preforms, and a device for reshaping the plastic preforms into the plastic containers, arranged downstream of the heating device in the transport direction of the plastic preforms, wherein the reshaping device includes a transport device, which transports the plastic preforms along a predefined transport path and wherein the transport device has a station carrier on which a multitude of reshaping stations are arranged, each having blow mold devices each arranged on blow mold carriers. The reshaping device includes a changing device, which is suited and intended for at least removing and/or attaching the blow mold devices to the blow mold carriers, wherein this changing device is further suited and intended for at least removing and/or attaching the changeable element to the heating device.

Apparatus for conveying granular material from a supply to receivers that retain and dispense the material when needed by process machine include a vacuum pump, an air flow limiter connected to the vacuum pump, a first conduit connecting the receivers to the air flow limiter, and a second conduit connecting the material supply to the receivers.

A device for turning over molds is provided that can reduce the wear of turning over wheels and supporting rollers even when the speed for transporting a flask or the speed for turning it over increases. A pair of turning over wheels (5) are attached to respective sides of a turning over roller conveyor (4), on which a metal flask (3) is mounted. The outer surfaces of the wheels are supported by respective pairs of supporting rollers (6). A driving roller (9) is provided on one or both of the wheels. The supporting rollers are flangeless. Two pairs of side rollers (10) abut the side surfaces of the wheels so as to prevent them from moving in the direction in which the flask is transported. The side rollers are preferably configured so that their surfaces that contact the wheels are formed as arcs.
