Abstract: The paper tray for an automatic sheet feeder has a tray base (2) to which is attached a lower paper alignment face (4) having a sheet ejection slot (6). An upper paper striking face (8) is located opposite the lower paper alignment face, in the vicinity of which is a set-count finger (10). The upper paper striking face (8) in the form of a striking block (9) which increases in thickness from the tray base (2) upwards is shaped in such a way that the documents returned to the paper tray can be relied upon to come to rest on top of the set-count finger (10).

Abstract: A device (1) for aligning sheets against two sheet abutments (3 and 5) which are disposed perpendicularly relative to each other consists of a rotatably mounted sleeve (6) in which a rod member (16) is guided. Rod member (16) is held in the sleeve by spring means (18). At least one aligning element (8) is mounted on sleeve (6) for pivotal movement about a pin (10), the aligning element being provided with a friction element (14) at one end. Spring means (24) connecting arm (12) of the aligning element with the lower end (22) of rod member (16) cause the friction element (14) to rest with a predetermined pressure force on the surface (4) of the uppermost sheet of paper.

Abstract: A device for directing individually supplied sheets onto a sheet depositing surface includes a feeder for feeding sheets along a sheet path onto the surface and a pivotably mounted sheet directing element that includes a first arm which extends across the sheet path. The pivotable directing element includes a weight mounted thereto above its pivot axis for increasing the moment of inertia of the pivotable directing element.

Abstract: Arrangements are disclosed for dispensing liquid in droplet form at timed intervals from a receptacle defining a liquid reservoir. The receptacle includes openings at opposite ends thereof defined in part by integral externally threaded neck portions. One of the openings is employed to fill the receptacle and control the venting of the interior of the receptacle to atmosphere, thus to control stopping and starting of drop dispensing. The other of the openings is a dispensing opening including dispensing and timing means through which liquid in the receptacle is dispensed and by which the rate of drop dispensing is controlled. Absorbent material may be supported beneath the receptacle to receive drops dispensed therefrom to facilitate evaporation of the liquid, and fan means may be associated with the receptacle and absorbent material to further facilitate evaporation of the liquid and entrainment of odoriferous vapors from the liquid into the moving airstream caused by fan operation.
