A three-dimensional object printing system comprises a ejectors configured to eject drops of material towards a platen, a heater, a sensor configured to sense temperature of the ejected material, a radiator configured to direct radiation to the ejected material, a cooler configured to cool the ejected material, and a controller operatively connected to the ejectors, heater, sensor radiator and cooler. The controller is configured to control the ejectors to form layers of material for a three-dimensional object on the surface of the platen with reference to image data of the three-dimensional object, to operate the heater to heat the surface of the platen, to compare a temperature signal received from the sensor to a predetermined threshold, to operate the radiator to radiate the object layers, and to operate the cooler to attenuate heat produced by the radiated material in response to the signal from sensor exceeding the predetermined threshold.

The present invention relates to a device for curing resin-impregnated lining tubes using high-energy radiation, comprising at least two radiation sources for generating high-energy radiation, wherein the device has a front end, a rear end, two oppositely situated side ends, a top end, and a bottom end, wherein a length of the device from the front end to the rear end is smaller in a transport state than in an operating state. At least one element of the device is foldably, displaceably, rotatably, and/or movably supported, and at least one first radiation source is situated farther from at least one additional radiation source in the operating state than in the transport state. The device includes a fastening point on which a tensile force can act, in particular in the longitudinal direction of the device in order to transfer the device from the transport state into the operating state.

A method can be used to attach a fabric member to a trim while forming a pattern in the fabric member. A trim has trim grooves formed in one side of the trim and a fabric member has a foam formed in one side of a skin material of the fabric member. A bonding member is coated to an outer surface of the foam and the fabric member is heated where the bonding member is coated. The heated fabric member is placed on the side of the trim where the trim grooves are formed. The fabric member is fixed to the trim by inserting edges of the fabric member into the trim grooves using insertion blades while pattern protrusions formed in a compression jig form a pattern by pressing the skin material of the fabric member.

An optical forming device includes a light source to emit light for causing liquid photocurable resin to undergo curing and an optical modulator to modulate the light for causing the liquid photocurable resin to undergo curing in a pattern based on a shape of a three-dimensional object, and irradiate the liquid photocurable resin with the modulated light. The optical modulator includes a liquid crystal device to modulate the light for causing the liquid photocurable resin to undergo curing in the pattern, and emit the modulated light as linearly polarized light and an optical retardation device to impart a phase difference to the linearly polarized light emitted from the liquid crystal device, and emit the light imparted with the phase difference.

Embodiments relate generally to a traction surface and methods for forming the traction surface. The traction surface may comprise a compound material comprising glass fibers oriented orthogonal to the surface of the compound material extending from the compound material, wherein when the traction surface contacts an icy surface, the glass fibers are operable to penetrate a liquid-like top layer of the icy surface to provide grip with an ice layer below the liquid-like top layer. The method for forming the traction surface may comprise integrating glass fibers into a compound material; orienting the glass fibers within the compound material such that the glass fibers are oriented approximately orthogonal to the surface of the compound material; splitting the compound material to expose the glass fibers, wherein the glass fibers extend from the surface of the compound material; and forming the split compound material into a traction surface.

A method and the device are used to control valves. The valves are arranged in the region of lines for a fluid. At least one first valve is in the form of a control valve arranged in the region of a primary line. At least one second valve is in the form of a switching valve. At least one branch is arranged downstream of the control valve in the region of a direction of flow. At least two secondary lines extend downstream of the branch. Each secondary line has one of the switching valves. The valves are connected to a control unit which coordinates the function of the valves.

An improved ventilation module is characterised by the following features, among others: a ventilation outlet channel (61) having a gas flow inlet side (61c) and an opposite gas flow outlet side (61d) is provided, the ventilation outlet channel (61) is separated in the longitudinal direction to form at least two ventilation channel portions (61a, 61b), such that the at least two ventilation channel portions (61a, 61b) are adjustable away from and towards one another transversely to the longitudinal extent of the ventilation outlet channel (61), whereby the width (B) of the ventilation outlet channel (61) and thus the flow cross section can be increased or decreased.
