Title: Tobacco product of variable tobacco density and apparatus for making such tobacco products
Inventor: BABEY JACQUES
IPC: A24D1/00
Filed: 1994-06-14
Abstract: When manufacturing a cigarette which is completely or partly formed of strands or sides of expanded tobacco or short strands, or else containing a smaller amount of tobacco, difficulties are encountered in obtaining a cigarette which has an acceptable measured compressibility value. By providing a cigarette-manufacturing machine (1) with a cam (3) which has at least one additional bearing surface (32A, 33A, 34A, 35A) it is possible, just before the operation (15) of nipping the top off the twist (20), to compress a certain number of regions (22) of the said twist, thereby increasing the tobacco density in these regions. A cigarette including one or more regions (22) with a tobacco density which has been increased in this way has a measured compressibility value which is equivalent to a normal cigarette. <IMAGE>

Title: Method of making an article of a polymer having painted surface
Inventor: SUSPENE LAURENT GERARD
IPC: C08J7/04
Filed: 1996-09-20
Abstract: A process for making a paintable polymer article is described which comprises impregnating a polymeric substrate having a plurality of pores, the pores having a number average pore cross-section of less than 50 square microns, with a liquid sealant having a viscosity less than 25 kPa.s and heating the impregnated polymeric substrate to cure the sealant. The paintable polymer article may be coated with a paint to form a painted polymer article. The inventors have found that this invention helps prevent paint popping due to the expansion of solvents trapped in voids in the polymer article during paint drying or curing operations, particularly paint popping caused by voids in the polymer article which are exposed by cutting or trimming the polymer article after compression molding.

Title: Gas-insulated switchgear employing sf 6 gas for power distribution networks
Inventor: DIRKS ROLF
IPC: H01H33/12
Filed: 1997-08-04
Abstract: An SF6 gas-isolated switch installation for several switchboard sections, each with a three-pole separating switch and an earthing device. A switchboard section is equipped with a separating switch designed as a transformer switch. This can be a load-break switch, whose phases are combined with cutouts, or a load-isolating breaker. The switch installation has for the support of mobile switch contacts and the connection of cables and/or cutouts appropriate lead-throughs in the housing walls and switch shafts mounted on said walls, as well as omnibus bars for the fixed contact of phases L1, L2 and L3, and individual phase quenching devices directly connected to the omnibus bars (9). The quenching devices of the load-break switches that do not function as as transformer switches are equipped with sheet steel quenching chambers. Breaking ability must be enhanced with no extra space requirement. For this purpose blow-out coils (13, 13a) are introduced according to an arrangement which when in off position meets the requirements for a disconnected section, with a contact arrangement corresponding to the remaining load-break switches for the three phases of the switch designed as a transformer switch.
