Abstract: A circuit for converting data of a signal line in the form of logical pulses of current to RS232 level voltages between an air-conditioner and a computer is described. The conversion circuit is able to troubleshoot the communication signals between the indoor unit and outdoor unit of an air-conditioner.

Abstract: A linear connector for joining hollow spacing profiles and hollow bar profiles of a multiple insulating glass. The connector includes a flat, longitudinal body which is to be inserted at one end into a first spacing profile and with its other end into a second spacing profile. The surfaces of the connector are provided with an abutment element positioned at its center. The abutment element touches the front faces of the spacing profiles on insertion of the linear connector into the spacing profiles which are to be connected to one another. The longitudinal body includes a double-T-cross-section having distantly parallel and horizontal cross-bars which are connected by at least one vertical center bar and contacted at least partly in the mounted condition of the linear connector by the opposing surfaces of the inner wall of the spacing profiles.

Abstract: Linear connector of plastic material for joining hollow spacing profiles A, B and hollow bar profiles of a multiple insulating glass, comprising a flat, longitudinal body which is to be inserted with its one end into the spacing profile A and with its other end into the spacing profile B, the surfaces of which are provided with an abutment element positioned in the center of the linear connector, which abutment element touches the front faces C and D of the spacing profiles on insertion of the linear connector into the spacing profiles which are to be connected to one another, wherein the mentioned longitudinal body comprises a double-T-cross-section the distantly parallel and horizontal crossbars of which being connected by at least one vertical center bar and contacted at least partly in the mounted condition of the linear connector by the opposing surfaces of the inner wall of the spacing profiles.

Abstract: A linear connector for joining metal spacing profiles for multiple insulated glass panes, includes a body that is adapted to be inserted into the hollow spaces of two spacing profiles. The body has a pair of brake blades positioned along lateral sides that are inclined toward the center. The brake blades are adapted to contact opposing front faces of the profile bodies upon insertion of the linear connector into the spacing profile. Spring blades project from the lateral sides of the body. The spring blades are positioned behind one another to form a V-configuration and are adapted to increase the frictional force between the body and the inner wall surfaces of the spacing profiles. Reinforcing elements, that are centrally positioned along lateral sides of the body, are connected to the said brake blades and are adapted to prevent passage of hygroscopic powder along the outside of the body.

Abstract: The invention concerns a linear connector of plastic material for joining hollow spacing profiles of multiple insulating glasses comprising a longitudinal body having a complete or essentially complete U-configured cross-section for the passage of a hygroscopic powder and being insertable into the hollow space of the one spacing profile as well as the hollow space of the other spacing profile of the two profile bodies to be joined. The surface of the linear connector is provided with abutment elements which are pushed against the opposing front faces of the profile bodies upon the insertion of the linear connector into the profile bodies. Moreover, the surface of the linear connector is provided with blade-like springs in order to create a strong seat between the body and the inner wall of the spacing profiles.

Abstract: The invention relates to a linear connector of plastic material for joining two parallel hollow spacing profile tracks or hollow bar profile tracks of multiple insulating glass units used for windows to reduce heat loss from building interiors and forming the frame between two glass panes of such a multiple insulating glass unit and surrounding such glass unit, which frame having two ends which are to be connected to one another by the linear connector, characterized in that the linear connector includes two pairs of two distantly separated parallel legs extending in longitudinal direction of the spacing profile tracks of the frame which are to be connected to one another and being adjacent to an abutment rib extending accross these longitudinally extended legs, which abutment rib is provided with front faces being engaged by the front faces of the hollow profile spacing tracks if the linear connector is in mounted condition.
