The disclosure includes a method and apparatus for protecting an air vent pipe. In one or more embodiments, a cover can include a plurality of sidewalls and a pipe portal disclosed through at lease on of the side walls. The distal end of an air vent pipe can be disposed through the pipe portal and into the internal volume of the cover. A clamp can secure the cover to the air vent pipe. An access door disposed in a side wall can give access to the clamp and distal end of the air vent pipe and closing and locking the access door with a locking mechanism can prevent unauthorized users from accessing the distal end of the air vent pipe.

One embodiment of the present disclosure provides an external detection see-through door of a cabinet that stores objects. The external detection see-through door includes a transmission window, a sensor configured to detect a specific external condition in front of the transmission window, a light emitting module configured to increase an amount of emitted light according to a signal from the sensor, which has detected the specific external condition, to increase an amount of light that is reflected from inside the cabinet and heads toward the transmission window, and an optical film that is provided on the transmission window and has a light transmittance that prevents the cabinet from being see-through from the outside before the sensor detects the specific condition and allows the cabinet to be see-through from the outside due to light that is reflected from inside the cabinet and transmitted through the transmission window and the optical film due to the light emitting module increasing the amount of emitted light according to the signal from the sensor that has detected the specific external condition.

A desiccant window includes: a transparent triangular prism that is disposed between first and second plates, is configured of a first side along the first glass and second and third sides which have an angle with respect to the first side in a sectional view, and forms (three) types of optical paths; and a desiccant heat receiving unit that has hygroscopicity and is disposed between the first and second plates, is installed on the second side of the triangular prism), and is received solar heat and releases absorbed moisture by heating using the received heat received.

A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

A system for a tilting amusement ride installed in a supporting structure and intended to bring a rider from a standing vertical position, to a tilted position while the rider remains prone, the ride comprising: a tilting platform comprising at least one cell to accommodate a rider; at least one actuator attached at its extending end to the platform by a pivoting attachment, wherein the actuator extends to tilt the platform and retracts to retract the platform; at least one back post attached to the at least one actuator at its fixed end by a pivoting attachment and securely attached to the structure; and a supporting frame attached to the platform by a rotational pivot, wherein the platform tilts about the pivot and wherein the frame is securely attached to the structure; wherein the platform has an angle of tilt between 15 and 45 degrees.

This showcase for conserving and displaying objects in a protected environment comprises a case, fixed walls, an openable wall and a gasket housed in a seat formed in part in the fixed walls and in part in the openable wall, open towards the interior of the showcase. The showcase ensures better security, since the gasket cannot be reached from the outside (unless the showcase is open) and therefore any possibility of tampering is avoided.

The invention relates to a door assembly (1) allowing a sealed transfer between two enclosed volumes, comprising a flange (2) arranged to delimit an opening in one of the enclosed volumes, and a door (4) that extends along an axis (C) and is hingedly fastened to/mounted on the flange (2) so as to move from a closed position in which the door (4) closes the passage opening (3), into an open position, characterized in that the door (4) is fastened to the flange (2) by a double-joint linkage mechanism (5) comprising a first joint (6) arranged to allow a rotational movement about an axis (A) perpendicularly to the axis (C) of the door by a maximum of 30 degrees in relation to the plane of the passage opening (3), and a second joint (7) arranged to allow a rotational movement about an axis (B) parallel to the axis (C) of the door.
