Abstract: An apparatus and method for bending glass sheets. In a first embodiment a heated glass sheet is moved into a bending section by rollers which are retracted to drop the heated glass sheet onto a mold where the glass sheet sags into a desired bent shape, then quenched between quench heads and lifted off the bending mold up to the upper quench head by air pressure, the rollers then close beneath the glass sheet and the glass sheet is deposited onto the rollers for conveying to a cooling station. In a second embodiment, the hot bent glass sheet is transferred on a mold from a bending section by a first shuttle to a position between the quench heads for quenching then removed from the mold by blowing air through the lower quench head until the glass sheet contacts an upper second shuttle which is transported to a blow-up section where the sheet is lowered onto a roller conveyor to a cooling section.

Abstract: A device for avoiding capsizing of catamarans, in which a mast of the catamaran is pivotally mounted on a transverse beam of connection between two hulls and kept in position by two shrouds which, starting from the top of the mast and winding around tensioning pulleys and positioning pulleys, are connected to a movable point of a piston device, which is of the oleodynamic-mechanical type and generally comprises a piston head kept in position in a cylinder by resiliency and made of two parts connected to each other by a calibrated helical spring. A pipe with a pump and unidirectional valves and for the oil of the oleodynamic device are provided outwardly of the cylinder. When the load on the mast exceeds the value of calibration of the spring, the piston head opens to uncover apertures for the passage of the oil which in this manner circulates and permits shifting of the piston head in the cylinder. The mast only bends if the wind acting on the sail exceeds the calibration value of the spring.

Abstract: During ceramic casting for the production of a molten bath it is often observed that the fire-resistant material becomes eroded and/or solid oxide phases are deposited. Both phenomena interfere with the smooth outflow of the molten bath. The present invention is intended, therefore, to provide an outflow which is stable in shape even when a molten bath is passed through, especially in multiple-sequence casting. To this end, the invention provides for ceramic casting with an envelope (10, 14) which is at least partly external and an internal insert (11, 14, 53) at a distance from the envelope (10, 14), the insert ( b 11, 14, 53) and envelope being connected together.

Abstract: A loudspeaker system includes at least two loudspeaker drivers, together with an electrical crossover network having filter circuits with at least two separate mutually exclusive frequency passbands. The filter circuits comprising the crossover network each possess brick-wall amplitude responses, i.e., passbands with very high band-edge amplitude vs. frequency response slops, on the order of 100 dB/octave in the better embodiments. The high passband band-edge slopes, which are realized by the inclusion of transmission zeros in the separate crossover filter transfer functions, takes together with further appropriate crossover filter transfer function synthesis causes the separate loudspeaker drivers comprising the loudspeaker system to function independently of one another in their contribution to total system acoustic output.
