Abstract: A self service printer is improved by providing for temporary storage of several printed documents to be issued as a bundle.

Abstract: A valve assembly controlled by a float permits pressure-free feed of a fluid into a pipeline system, the valve being assigned in operative relationship with a channel which is arranged in the base of the tank containing the float, the channel extending laterally to the normal axis of the tank. The valve is designed as a dual valve with two valve members arranged on a valve rod guided in the direction of the axis of the tank and the channel is defined through a pair of apertures lying opposite each other in the direction of the axis of the tank with valve seats being located about the apertures, the valve members arranged on the valve rod operating to engage and disengage the valve seats to open and close the apertures.

Abstract: An apparatus for separating documents from one another includes two spaced-apart rollers which define a gap therebetween. The rollers rotate so that the surfaces which face one another move in opposite directions. One of the rollers serves to transport a document in the conveying direction, while the second countermoving roller serves to hold back any additional document which has been fed on top of the first document. The second roller is mounted so as to be pivotable, so that the gap between the rollers can be adjusted in accordance with the document conveyed through the gap. A guide roller serves to maintain the gap between the rollers. A storage container for the documents has movable rearward and bottom walls, wherein the rearward wall is biased by a tension spring so as to exert an essentially constant pressure on the stack of documents.

Abstract: A document encoder is described, which is conceived as a compact desk set. In order to serve as a multi purpose unit and in spite of that exhibit a compact type of construction, the various printing devices (2, 4, 6, 7, 8) and print backings (41, 42; 47; 55; 64, 71) impacting the document from its front- and back side are arranged stationary in a chassis (1), while the printing process in direction of the lines is accomplished solely through conveying the document by means of a conveyor device. The print devices and the print backings are arranged so that they apply print to the front- and back sides of the document in a partially overlapping way. The document conveyor path (10) is U-shaped, whereby the input station (11) is located at one leg of the conveyor path (10), the printing devices (2, 4, 6, 7, 8) at the other leg (15). The printing mechanisms themselves are either type wheel printing mechanisms (3), stamping print mechanisms (4, 6) or needle print mechanisms (7, 8), according to the desired needs.

Abstract: A hose connection, particularly for use in motor vehicles, is proposed which ensures a gastight connection already with a low starting torque, is usable repeatedly and whose structural component parts are non-detachably held together in an assembly unit. Supported on the shoulder (7) of a stepped hose sleeve (1), which shoulder (7) is smaller in diameter, is a hollow screw (2) which, when the hose connection is assembled at a rigid duct body (15), presses together a sealing ring (3), which is arranged on the shoulder (8) and has a larger diameter, only until the sealing ring (3) abuts at the end face (22) between the shoulders (7) and (8) of the hose sleeve (1).

Abstract: A method for positioning a switch in a speed limiting device, wherein, for a limit switch, which interrupts the controlling process of the speed limiting device consisting of an electronic control unit, an electromechanical servo unit and a mechanical clutch arrangement, a positioning method is utilized and in order to carry out this method, an arrangement is provided in which the limit switch is fastened on a slide which is displaceably supported with the servo component of the speed limiting device. Arranged in the slide, which, in addition, carries a switchover contact bank serving to actuate the switch, there are provided locking bars with which, together with catch paths constructed at a housing of the servo unit, an exact fixing of the slide can be achieved at the end of the positioning process by means of reversing the rotational direction of the servo motor.
