The invention relates to a vertical sliding element including an element frame and a sash which can be moved in the vertical direction relative to the element frame. In the closed position of the sash, one fitting chamber each is formed in the intermediate spaces which are laterally limited by mutually facing side faces of the sash and the element frame. Each fitting chamber is provided with a guide rail and guide elements guided in the guide rail. The sash is connected to the guide elements via a scissors' arrangement having a plurality of parking scissors. The scissors arrangement is designed for parallel parking of the sash in a partially open position, in which the sash is positioned in front of an opening in the element frame, seen in the horizontal direction, and wherein the guide elements are designed to move the sash parked in parallel in the vertical direction by moving the guide elements in the guide rails.

A moving coil, constant force, curl spring window balance assembly for installation in a hung window assembly comprising a sash is disclosed. The window balance assembly can include a carrier, a mounting bracket, a curl spring and a sash support bracket. The sash support bracket can be positioned intermediate the carrier and the mounting bracket. The sash support bracket can selectively engage at least one of the carrier or the mounting bracket. The sash support bracket is operable to supplement the counter-balance or holding force provided by the curl spring of the window balance assembly against the weight of the sash when the sash is in a raised position.

The present disclosure provides a barrier operator system in which a remotely located transceiver type controller is in wireless communication with a transceiver type adapter connected to a barrier operator, and in electronic communication with the barrier operator's microcontroller. The controller is operable to wirelessly transmit door operator status inquiries to the adapter. This may be effected automatically in connection with the transmission and receipt by the adapter of door toggle commands or separate and apart from same. The status information is wirelessly transmitted by the adapter in broadcast form without source or destination address to the remote device in a signal that is non-addressed broadcast door operator (and, indirectly, door) status information by relying upon the receipt of the message by the remote within the specific time limit of the reception window of the remote.

A motor-driven cover device for covering and releasing a charging port arranged on the vehicle body of an electric vehicle with respect to a vehicle exterior. A cover plate can cover the charging port in a closed state, a motor can be operatively connected to the cover plate for driving an opening movement and a closing movement of the cover plate. A force transmission device can transmit a motor power for carrying out the opening movement and closing movement of the cover plate. A guide element can guide the cover plate along a movement path during the opening and closing movement of the cover plate. The cover plate can be moved along the vehicle body in a motor-driven manner during the opening and closing movement, the vehicle body covering the cover plate at least partially with respect to the vehicle exterior in an open state of the cover device.

The invention relates to a medical washer/disinfector, comprising a washing chamber for receiving medical articles to be washed/disinfected, an opening for accessing the interior of the washing chamber, a door which is movable from a lowered open position to a raised stop position and then to a raised closed position. The door is associated with a first slide surface. The medical washer/disinfector also comprises a carrier arrangement vertically movable by a motor, the carrier arrangement comprising a second slide surface for enabling slidable contact with the first slide surface. A spring member extending vertically upwardly from the carrier arrangement to a connection area of the door. The door is pushed upwards by the spring member until the door reaches said raised stop position. Continued upward movement of the carrier arrangement causes the spring member to become more compressed, whereby the door moves horizontally from the raised stop position to the raised closed position.
