Title: Paper matrix for heat and moisture transference in air conditioning - is impregnated with copper and hygroscopic salts
Inventor: BURGER GUENTHER DR RER NAT
IPC: D21H17/67
Filed: 1977-01-31
Abstract: Matrix for rotating heat and/or moisture transmitters, consists of layers of corrugated fibrous material forming axial channels, in which the layers consists of cellulose paper impregnated with0.-3% Cu as low-solubility basic carbonate or borate, and with hygroscopic salts, pref. 10-35% LiCl. The front face of the matrix is consolidated with a cold-hardening synthetic resin, esp. of urea-formaldehyde type. For use in regenerators to recover the enthalpy from the waste air from air-conditioned rooms, by alternate passage of waste air from air-conditioned rooms, by alternate passage of waste and fresh air through the matrix as it rotates. Health hazards from use of asbestos paper are eliminated and cost is reduced. Presence of Cu salts prevents microbial degradation of the paper, and the LiCl gives non-flammability as well as hygroscopicity.

Title: Fluidisation of bulk materials normally difficult to handle - using very intense local aeration with jets on arms rotating round the base of the bed (NL 14.11.78)
Inventor: SCHIRNER ROLF DIPL ING
IPC: F26B3/084

The outlet air velocities have a value which is 5-200 times the suspension velocity of individual particles. The circles of rotation of the various outlet jets for the air can be arranged with geometrical regularity or without it. The spacing of the jets lies between. K square root of (4A/pi n) and 0.5 d (where k is the air jet divergence constant, A is the total area of the air outlet opening in m2; n is the number of air jets and d is the dia. of the fluid bed vessel).
