Title: Aerosol particle charge and size analyzer
Inventor: MAZUMDER MALAY K
IPC: G01N15/14
Filed: 1986-08-12
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE          An instrument for analyzing the size and charge of aerosol particles employs a dual beam laser Doppler velocimeter to track the motion of a particle while subjecting the particle to a sinusoidal acoustic field and to a pulsed, high voltage electric field.  The particle transitting through the crossed beams of the laser Doppler velocimeter moves with an oscillatory motion due to the acoustic field and, if the particle is charged, it has a horizontal drift parallel to the electric field during the electric pulse.  The phase lag of the particle's motion with respect to the acoustic field is measured to determine the aerodynamic diameter of the particle and the velocity and the direction of the drift relative to the polarity of the applied high voltage electric field is used to determine the magnitude and polarity of the electric charge of the particle.

Title: Process for producing a tangled fibre material from glass fibres and polymer for the production of glass fibre-reinforced plastic mouldings and apparatus for performing the process
Inventor: EHNERT GERD
IPC: D04H1/00
Filed: 1987-08-31
Granted: 1994-07-12
Abstract: A B S T R A C T      For producing a tangled fibrous material from cut glass fibre bundles, the latter are fed into a compressed air flow and the glass fibre-laden air is deflected into a turbulent eddy flow of varying direction, so that a tangled fibrous material of wadding-like consistency is formed.  Through the simultaneous addition of dry polymer-based binder powder, it is possible to obtain a tangled fibrous material as a starting product for the production of glass fibre-reinforced plastic mouldings, which can be compressed to a felt.  This can in turn be packed as an intermediate or further processed in a heated belt press to glass fibre-reinforced plastic plates.

Title: Stacker apparatus
Inventor: ZOUZOULAS JOHN
IPC: B65H29/46
Filed: 1987-09-04
Granted: 1991-11-26
Abstract: Abstract An improved banknote stacker is described which achieves reduced levels of jamming and improper stacking.  A banknote is directed to a prestorage compartment using a pulley, belt and roller drive assembly.  During a pusher cycle, a pusher plate drives the banknote from the prestorage compartment into a banknote storage magazine, and then the pusher plate returns to its original position.  Just prior to the pusher cycle, rollers in the roller drive assembly are retracted to release the banknote.  The pusher plate is specially designed to prevent banknote slippage, and it is preferably driven by the same drive mechanism which retracts the rollers to insure that a pusher cycle will follow shortly after the retraction of the rollers.
