Abstract: Chaudière multitubulaire à passage unique de type quadrangulaire ayant un agencement dans lequel un trajet d'alimentation en air comburant, une chambre de combustion et un canal de gaz de combustion traversant un conduit de fumées sont alignés substantiellement dans le même plan, et dotée d'un conduit de brûleur et d'un ventilateur posés chacun à l'endroit souhaité dans des parties de la paroi extérieure définissant la largeur du corps de la chaudière. Le corps de la chaudière comporte un ensemble de tubes d'eau placés substantiellement à la verticale, de sorte que les gaz de combustion s'écoulent transversalement par rapport aux tubes d'eau. Un brûleur est placé en étroite proximité avec la première rangée de l'ensemble de tubes d'eau, de sorte que même si du combustible venant du brûleur est allumé dans un espace entre la première rangée de tubes d'eau et le brûleur, la combustion effective ne s'y complète pas, mais la plus grande partie des imbrûlés se consume complètement en s'écoulant dans les espaces libres entre les tubes d'eau.

Title: Member for securing insulation panels
Inventor: SCHMIDLE JOSEF
IPC: E04F13/08
Filed: 1990-09-21
Granted: 1998-09-15
Abstract: A member for securing insulation panels to a structural component is formed of an annular head and an axially extending hollow shaft extending from the head.  The hollow shaft is arranged to receive a nail for fixing the member to  the structural component.          An axially extending section is positioned within the hollow shaft and has an abutment at its end closer to the head.  When the nail is driven into the structural component its head contacts the abutment and at least an axially extending part of the section is collapsible to compensate for excess driving energy supplied to the nail whereby it is inserted for variable depths into the structural component.  The collapsible part of the section prevents compressive forces from exercising any damaging effect on the insulation panels.

Title: Magnetic key operated lock
Inventor: SEDLEY BRUCE SAMUEL
IPC: E05B47/00
Filed: 1990-02-15
Granted: 1996-09-24
Abstract: In a magnetic key operated lock a slide member carries a plurality of wheels which carry magnet pins.  The position of the pins forms part of a code of the lock.  The wheels are caused to rotate by insertion of a key having a code for unlocking the lock and moving the slide member.  As the slide member moves, one of the pins which is repelled by the key abuts a stop which thus causes the respective wheel, and so the other wheels, to rotate.  By having wheels of two different sizes, the smaller wheels can be made to rotate more than once before a code is repeated.  An abutment is formed by pressing a tang from stationary wall in the lock. Variations in which a single wheel may have more than one abutment associated with it so that a magnet pin can be used to change the code when it is in more than one position, and a wheel may pins of different polarities with respect to the key are also disclosed.

Title: Coil structure and coil container
Inventor: FUKUMOTO HIDESHI
IPC: F17C13/00
Filed: 1992-03-19
Granted: 1996-09-24
Abstract: There is disclosed a coil structure which is rapidly energized or excited, and reduces the generation of heat in a coil container by eddy current due to a dynamic disturbance such as vibration and a magnetic field fluctuation, thereby suppressing the generation of a quench.  The coil container is constituted by a low-resistivity material, and a high-resistivity portion is provided at at least one portion of the coil container in the direction of the periphery of the coil container. The high-resistivity portion is provided at a position where a vibration displacement is small or a magnetic field fluctuation is small.  When the coil structure is to be energized or excited, the eddy current produced in the direction of the periphery of the superconducting-coil container can be reduced at the high-resistivity portion, and when the dynamic disturbance develops, the generation of heat by the eddy current is suppressed by the low-resistivity material.
