A guide pin support system may include: a first support plate; a second support plate pivotally attached to the first support plate; a first guide pin supported by the first support plate; a second guide pin supported by the second support plate and the second guide pin pivotable with respect to the first guide pin.

The invention relates to a refinement of a spindle drive (1), and to a louvered window or a louvered shutter having a spindle drive for moving louver elements such that applied return forces and return torques can be absorbed better, and in particular without placing a load on the drive motor. For this purpose, the spindle drive (1) has a specially designed return stop mechanism (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).

A slide-and-swing wing system includes at least one rail profile. At least two wings, each displaceably mounted in the at least one rail profile via two support elements The at least one rail profile has a lateral outlet opening for unlatching a support element of a wing. One wing functions as a door leaf which, with all other wings in the latched state, is pivotable into the remaining opening. A closure mechanism makes it possible to prevent the door leaf from being opened and includes a drive, and also an operating part, via which the drive can be actuated. The door leaf is displaceable, via the drive, in the rail profile in the direction of the adjacent wing to such an extent that no support element of the door leaf is aligned with the outlet opening, thereby preventing a support element from coming out through the lateral outlet opening.

A fitting arrangement for a leaf of a sliding window or door that can be moved away in parallel, includes a control unit having a mounting part for fixing on the leaf and an adjusting part which is displaceable relative to the mounting part for moving the leaf away in parallel. A movement unit is fastened to the control unit and has an energy storage device and an activation element for the energy storage device. A closure arrangement for a building opening, includes a frame, the control unit and the adjusting part. The leaf which, in a closed position, can, by means of the control unit, be brought up to the frame and be moved away from the frame in parallel, so the leaf is displaceable along a guide rail of the frame. The movement unit supports an automatic movement of the leaf along the guide rail.

A tilt-up door for a building having a relatively wide door opening having a door panel including top and bottom horizontal members and vertical side members connected to the top and bottom horizontal members. The vertical side members each include a pivot point, affixed to pivot translation points which move upward or downward when an actuator is activated, such that first and second cams, each connected to one of the at least two vertical side members of said tilt-up door, each affixed at its lower aspect to each side member at a position at or slightly above the center point of the door frame, and each cam extending upwardly and arcuately toward the interior of the building, to a point in space where said cam contacts a cam follower extended inwardly at approximately a right angle with respect to both the adjacent top horizontal members of the door frame, and to the Support Structure or stile to which it is fixed at its proximate end, thereby guiding the door as it is moved between its substantially open substantially horizontal position, and to be lowered into its substantially vertical substantially closed position. Each pivot translation point is lifted or lowered by means of an actuator, such as a screw, chain or hydraulic system, depending upon the needs of the user or environment, which causes the door to open or close. The door panel contains an integral track or cam which is substantially elliptical having a radius such that each integral track rides on a stationary roller which allows the panel to tilt into position. The actuation system is mounted on or in columns on either side of the door to allow the door to move into the various open and closed positions.

A gate system and related control systems and methods include a frame assembly and a tracking assembly coupled to the frame assembly. A door is in mechanical communication with the frame assembly. Related methods for operating a gate of a gate system, where the gate is set to manual mode to manually open or close the gate. Additionally, control systems include a fail-safe programmable logic controller (PLC) circuit for controlling the gate for opening and closing a gate that employs redundant fail-safe features. The control system includes a safety PLC circuit having a PLC including a first input terminal and a second input terminal, and a light curtain switch electrically coupled to the first and second input terminals.

A spindle drive, a spindle nut for the spindle drive, and a louvre window or louvre shutter having a spindle drive for moving louvre elements. The spindle nut is constructed in multiple parts including a screw nut part, having an internal thread to engage on an external thread of the threaded spindle, and a bearing part in which the screw nut part is mounted. The screw nut part includes a driver structure for transmitting a drive force applied by the threaded spindle to the spindle nut onto an element to be driven. Furthermore, the screw nut part is rotatably mounted in the bearing part in such a way that the screw nut part executes a relative movement in relation to the bearing part, and a directional component of the movement is transverse to a thread longitudinal axis of the internal thread.

A method of making a composite pipe has the steps of (a) providing one or more sources of composite tape, the composite tape being formed of reinforcing fibres embedded in a thermoplastic matrix; (b) helically winding the composite tape(s) around a cylinder under the application of heat to form a pipe comprising fused, concentric layers of adjacently positioned, helically-wound composite tape; (c) scanning a region where edges of wound composite tape are expected to be, to generate scanning information; (d) controlling the gap between further adjacent windings by (1) using the scanning information to determine wound composite tape edge position(s), and (2) using the determined wound composite tape edge position(s) to adjust the winding process during winding; (e) repeating steps (c) and (d). The invention also relates to a corresponding apparatus for making a composite pipe.

A sliding door assembly includes an upper track assembly; a lower track assembly; a sliding door laterally slidable along each of the upper track assembly and the lower track assembly, the sliding door comprising a door body, an upper locking pin, and a lower locking pin, the sliding door configurable in a locked configuration and an unlocked configuration; and an actuator operatively connected to each of the upper locking pin and the lower locking pin; wherein, in the locked configuration, the actuator simultaneously engages the upper locking pin with the upper track assembly and the lower locking pin with the lower track assembly to prohibit the sliding door from opening, and in the unlocked configuration, the actuator simultaneously retracts the upper locking pin from the upper track assembly and the lower locking pin from the lower track assembly to allow the sliding door to open.
