Disclosed is a holder for stabilizing a linear shaped charge during epoxy curing. The device includes a support with a rectangular midsection having a first and a second end, and a central aperture; a pair of stair-step risers extending down from the first and the second end; and a pair of curved legs extending from the stair-step risers. The pair of curved legs lock the support onto a container. A linear shaped charge is positioned within the central aperture and extends downward into the container where it is stabilized while a curing agent within the container hardens. The support removes the need for constantly checking the alignment of the liner shaped charge while curing and prevents the need for sanding, both of which save considerable time when compared to previous methods. The support is designed with a raised midsection to prevent it from being bonded to the epoxy during the curing process, thereby allowing it to be reused.

A system can include an array of at least one heat source adapted to heat a stack including a superstrate, a substrate, and a polymerizable composition between the superstrate and the substrate, and at least one actinic radiation source adapted to at least photocure the polymerizable composition to form a photocured planarization layer. Implementations of the system can allow more flexibility regarding heating and exposure operations and may allow a system to occupy less area. Separate stations for heating a pre-cured layer of a polymerizable composition and exposing the pre-cured layer is not required. The array of actinic radiation sources and heat sources allow greater flexibility with respect to timing for heating and exposing to actinic radiation the pre-cured layer. The system can be used in a method that forms a photocurable planarization layer from a pre-cured layer of a polymerizable composition.

A composite curing system includes system includes a constraining container and an expandable medium. The constraining container includes a base and a cover and has an interior volume. The constraining container is configured to enclose at least a portion of a composite structure. The expandable medium configured to be disposed within the interior volume between at least a portion of the constraining container and the composite structure. The interior volume of the constraining container is selectively variable.

A drive unit for a molding machine for longitudinally displacing a movable first machine component relative to a second machine component, includes a rotationally drivable spindle mounted in a linear movement-locking manner on the second machine component, a spindle nut arranged in a rotational movement-locking manner on the first machine component for positive-locking engagement with the spindle, and a fluid chamber which at least adjoins the spindle and/or the spindle nut, and contains a lubricant. A temperature control element for controlling the temperature of the lubricant is arranged in and/or on the fluid chamber at least in areas.

A film forming apparatus includes a movable stage; a substrate holder supported by the movable stage and configured to hold a substrate; a coupling configured to couple the movable stage and the substrate holder; and a curing unit configured to cure a curable composition on the substrate, wherein the coupling includes: a kinematic coupling; and an attraction force generator configured to generate, between the movable stage and the substrate holder, an attraction force for fixing the substrate holder to the movable stage.

Provided herein are methods of forming and optimizing cured features on a surface including controlling the surface upon which the cured features are applied. Additionally, a system for forming and processing the topographical features on the membrane is also described, along with mechanical features at specific system stations. More particularly, provided herein are methods of forming and optimizing topographical features applied to a membrane surface by controlling the membrane surface and by controlling the direction and magnitude of pressure applied to the membrane (substrate), as well as initially partially curing the topographical features, followed by fully curing of the topographical features to form the membrane having topographical spacing features formed thereon.

An oven for heating a fibrous mat includes a first conveyor for conveying the mat in a forward direction, and a measurement system inside the mat, including a sensor mounted on the first conveyor and adapted to move, in a transverse direction of the mat, between a first retracted position inside the conveyor and a measurement position inside the mat under the effect of an activation system, the measurement system being such that the sensor is connected by a mechanical transmission system to a finger projecting on a lateral side of the first conveyor, and the activation system includes at least one contact surface located facing the lateral side of the conveyor and adapted to engage with the finger, when it moves in the forward direction in order to move the sensor from its retracted position to its measurement position by the mechanical transmission system.

A stretching unit for stretching a film is disclosed having an oven and a compensation device. The compensation device includes an air conveyor, the first compensation opening and a second compensation opening, in which the first compensation opening and the second compensation opening open into the oven on opposing sides of a central plane (M) of the oven in the vertical and drawing directions (H, R). The air conveyor is located in terms of flow between the first compensation opening and the second compensation opening, in which the compensation device is configured to remove a volume of air from the oven through one of the compensation openings and to feed the removed volume of air into the oven through the other one of the compensation openings.

A device for cooling and stabilizing a cured tyre, includes a beam with a non-movable element; a movable element; a guide; and an actuator arranged to move the movable element along the guide relative to the beam. One of the non-movable element and the movable element includes a shaft having at its end a spline, and a first disc in the axis of which the shaft is arranged. The other of the non-movable element and the movable element includes a closing mechanism including a second disc with a threaded axial opening, a main electric motor and a securing socket having a cylindrical shape with a thread. The closing mechanism is configured to cooperate with the shaft via the securing socket corresponding to the shape of the spline and to adjust the size of the tyre through sliding, along the axis, of the second disc.
