Title: Paper handler with several bins for copier or printer - determines which bins hold items to be stapled and decides whether sheet position is correct
Inventor: HOSOI MASATOSHI
IPC: B65H31/34
Filed: 1990-01-18
Abstract: The paper handler has several bins, a sorter for distributing sheets to individual bins, a mechanism for positioning the sheets, and a stapler for sheets on the tins.

Patent DE-4003564-A1 (DE)
Title: Removing particulates from exhausts and flue gases
Inventor: COLLETTA ANGELO
IPC: B01J19/08
Filed: 1990-02-06
Abstract: The particulate removal device comprises a two-pole high-voltage generator and a number of conductors alternately connected to one or other of the poles. The conductors each consist of a conductive metal grid arranged inside the pipe perpendicular to the general direction of flow of the exhaust gases. The ratio between the cross-sectional area of each grid and that of the pipe cross-section is pref. less than 50% and more than 10% and pref. less than 35% to provide a good balance between not unduly obstructing the cross-section of the pipe while having an adequate area covered by the electric discharge. Alternatively, the conductors can consist of grids and/or plates and/or wires, e.g. arranged to form flats or tubes, set parallel to the general direction of flow of the exhaust gases. The conductors may have points protruding at right angles from their surface. The voltage supply to the conductors is preferably such as to provide an electric field between 50 and 98% of that which would cause a discharge in the gas at the operating temperature and under the relevant working conditions. A valved conduit or line and a pipe introduces air into the pipe and is controlled using a probe which analyses the exhaust gas and transmits the results to a microprocessor which controls a pump and a valve for introducing the desired quantity of air into the pipe upstream of the conductors.

Title: Detector for longitudinal cracks in conveyor belts - has pressure drum to cause gapping of any crack and subsequent cessation of drive
Inventor: PETER ANDREAS
IPC: B65G43/02
Filed: 1990-04-05
Abstract: The belt (1) is guided in the lower run (return run) shortly after the drive drum over a special drum structure which causes the damaged parts of the belt to gape apart. This is detected by a change in the distribution of the bearing forces of a pressure drum (3) which is mounted movable vertically to the direction of movement (7) of the belt (1) and results in the drive being switched off. The pressure drum (3) whose diameter tapers towards the centre, together with the guide rollers (2) which are mounted in their axes inclined to the moving direction (7) of the belt, cause an even distribution of the belt tension force over the entire belt cross-section. USE - Reliable maintenace-free detection of longitudinal cracks in conveyor belts.
