Abstract: A sorting apparatus for sheets of documents or the like, in which the sheets are conveyed on a conveyor belt, and are deflected by controllable deflectors into stacker bins. Roller transporters convey the sheets of documents from the deflector into each stacker bin. The drive of the roller transporters is effected by a driven belt common to the roller transporters of all stacker bins; this belt is activated only for the specifically chosen stacker bin with the roller transporter (26) corresponding to this bin. This actuation is accomplished by a clutch wheel which is tilted by a lever activating the deflector.

Abstract: While driving, the foot of the driver of a motor vehicle moves frequently back and forth between the gas pedal (22) and the braking pedal (24). In order to prevent the heavy wear of the shoe in the heel region caused by this motion, a device is described which provides a support device (belt band 20) for resting the foot, which support device is movable in cross direction in front of the gas pedal (22) and in front of the braking pedal (24).

Abstract: A sheet-feeding device for feeding individual sheets to the platen of a printing apparatus from a single storage unit or a plurality of storage units is provided. The sheet-feeding device incorporates selecting discs incorporating a switching arrangement for the purpose of establishing a driving connection with the associated printing apparatus to a separating roller for withdrawing a sheet from the selected storage unit. In the storage units which have not been selected, the switching disc prevents inadvertent activation of the non-selected storage units by a blocking device controlled by a counter which permits the switching arrangement to be blocked during the printing process in order to prevent undesired sheet feeding.

Abstract: In order to be able to retrofit an existing writing desk in simple fashion with a standup desk that can be folded and slid beneath the working surface of the writing desk, the standup desk has a frame on which the guides for sliding the standup desk are provided. This frame can be placed as a free-standing bracket beneath the writing desk or tensioned between the pedestals of the writing desk or between the floor and the working surface.

Abstract: A desk having a lectern and apparatus for slidably guiding the lectern into a resting position under the top of the desk and for enabling the lectern to be pulled from the resting position into a working position in which the lectern projects over the desk top. The lectern is supported in the working position by at least one extension, at least one supporting arm, and apparatus secured beneath the desk top for slidably receiving the extension.

Abstract: The invention relates to an apparatus for feeding single sheets from a stack of paper stored in a magazine to the platen of an office machine. The apparatus is capable of being mounted on the office machine, the drive of a separate-feed roller frictionally engaging the stack of paper being effected by means of the platen in such a manner that when the platen is rotated counter to the direction in which the paper is inserted, the separate-feed roller is driven in the direction of paper insertion. In order to prevent the separate-feed roller from hindering paper insertion by the platen, the magazine pivotally engages a control cam. The control cam is driven by the platen in such a manner that it pivots the magazine against the separate-feed roller when the platen is rotated counter to the direction of paper insertion; when the platen is rotated in the direction of paper insertion, the control cam pivots the magazine away from contact with the separate-feed roller.

Abstract: The invention relates to an apparatus for feeding and stacking single sheets for a printing office machine. Singel sheets (32) may be selectively called up from a plurality of magazine units (30), which are disposed vertically one after another. The single sheets are guided to the printing cylinder (12) by way of a horizontally disposed feed-in conveyor track (20) traveling below the magazine unit (30). The printed single sheets are stacked in sorted fashion in stacking receptacles (70) by way of a horizontally disposed delivery track (66,68) provided with controllable delivery diverters (72) and traveling below the feed-in conveyor track (20), the stacking receptacles (70) being disposed vertically one after another below the delivery track. The induction channel leading from the feed-in conveyor track (20) to the printing cylinder (12) crosses the ejection channel leading from the printing cylinder (12) to the delivery track (66,68).

Abstract: An apparatus for supplying sheets of paper to the printing platen of an office machine, for example a typewriter or bookkeeping machine. The paper is held in a stack within a removable cassette which can be placed in substantially vertical position into a cassette holder. The cassette is locked in the cassette holder by a slight rearward rotation which causes the engagement of a locking bar with suitable recesses in the cassette. When rotated into the operative position, a spring-loaded pressure plate urges the paper stack against a rotating separating roller which transports the top sheet from the stack in the direction of the printing platen of the office machine. The cassette also includes top sheet separating tabs which hold the corners of the top sheet for a limited time after the separating roller has begun the transport of the sheet, whereafter the top sheet snaps out of position.

Abstract: An apparatus for feeding single sheets of paper to a printing office machine, for example a typewriter, bookkeeping machine, etc. The paper is held in a stack within one or more magazines and the top sheet of the stack is engaged by a separating roller which is driven by a gear belt from the printing platen or another rotating part of the associated office machine. In order to insure the exact positioning at the entrance of the printing platen slot of the sheets of paper delivered by the separating roller, the apparatus provides that when the separating roller transports a sheet of paper forward to the printing platen, the printing platen is rotating backward at that time, preventing entry of the new sheet but insuring its position while the continued motion of the separating roller causes the new sheet to bulge. Thereafter, the direction of motion of the printing platen is reversed, causing the reliable advance of the paper into the office machine.
