Title: Polymeric materials
Inventor: WARD IAN MACMILLAN
IPC: A61K6/891
Filed: 1992-03-06
Abstract: 2081469 9215440 PCTABS00016 Polymeric monoliths having high stiffness and strength can be produced by heating an assembly of polymer fibres under a contact pressure to a temperature at which a proportion of the fibre is selectively melted and then compressing the assembly. Preferably at least 5 % of the polymer is melted so that on compression the molten materials fill the voids within the assembly. The use of polyolefin fibres especially melt spun polyethylene fibres is preferred. The products are useful e.g. as orthodontic brackets, bone prostheses and in body armour.

Abstract: A linear electromagnetic actuator (22, 22') has its core (26; 26') mounted to a can body forming apparatus (10) and its coil (28) attached to re-draw sleeve (14) of such apparatus (10). The actuator (22, 22') provides for the axial movement of the re-draw sleeve (14) between its fully retracted position and its fully extended position. The re-draw sleeve (14) and the coil are coaxially mounted to each other so that the force exerted on the re-draw sleeve (14) is also coaxial. Once the re-draw sleeve is in its fully extended position, an electromagnet (142) is turned,on so that the re-draw sleeve (14) exerts the requisite force on the can material preform (17). The electromagnet (142) is mounted coaxially about the re-draw sleeve (14) and exerts its force on a magnetic material ring (42) mounted to the re-draw sleeve (14) to hold the re-draw sleeve (14) against the can material preform (17).

Title: Process for adjusting the moisture content of tobacco
Inventor: WINTERSON WARREN D
IPC: A23L7/10
Filed: 1993-10-25
Abstract: A process for reordering tobacco, which results in no significant decrease in equilibrium tobacco CV or significant tobacco degradation, is provided. Tobacco to be reordered is contacted with an air stream having a relative humidity near the equilibrium conditions of the tobacco. As the OV content of the tobacco increases, the relative humidity of the air stream contacting the tobacco is increased to affect reordering of the tobacco.      Also provided is a process for drying tobacco, which results in no significant change in equilibrium tobacco CV or significant tobacco degradation. Tobacco to be dried is contacted with an air stream having a relative humidity near or below the equilibrium conditions of the tobacco. As the OV content of the tobacco decreases, the relative humidity of the air stream contacting the tobacco is decreased to affect drying of the tobacco.      It has been found that tobacco can be reordered or dried successfully in a continuous manner using a self-stacking spiral conveyor.
