Abstract: A device (2) for determining an intraocular pressure of an eye comprises a measurement arrangement with a measurement body (44), attached to a measurement arm (40), for applanation of the eye and a rotary knob (10) which is attached to a shaft (6). The measurement arm (40) is attached radially to a pivot axis (32) and the measurement arrangement comprises a mechanical coupling between the rotary knob (10) and the pivot axis (32), with a rotation of the rotary knob (10) being able to generate an applanation force required for applanation of the eye. The mechanical coupling comprises tension transmission means (12) attached to the pivot axis (32) via a first lever arm (34), and to the rotational axis (8) of the shaft (6) via a second lever arm (6).

Abstract: A device (2) for determining an intraocular pressure of an eye comprises a measurement arrangement with a measurement body (44), attached to a measurement arm (40), for applanation of the eye and a rotary knob (10) which is attached to a shaft (6) and can rotate about a rotational axis (8) of the shaft (6). The measurement arm (40) is attached radially to a pivot axis (32) and the measurement arrangement comprises a mechanical coupling between the rotary knob (10) and the pivot axis (32), with a rotation of the rotary knob (10) around the rotational axis (8) being able to generate an applanation force required for applanation of the eye.

Abstract: A storage apparatus has a card-accommodating, vertically upright stack-storage cassette (1) and a card-input, -reading and control unit (3) arranged adjacent to the top cassette-border region (4). The stack-storage cassette (1) has a vertically running storage opening (5) arranged in a cassette side. The storage apparatus also has a lift unit (7) which can be displaced vertically in said opening (5) and has a lift housing (19a, 19b). The lift unit (7), for its part, has a depositing plate (9) for the cards, which comes to rest in the store interior (10). The lift unit can be removed in the lowermost region of the cassette (1), to be inserted into the cassette (1) at the top and, acting on the opening borders, to be displaced vertically, i.e. lowered, in each case preferably by the distance of a height over which a group of cards is deposited, in order for the cards to be deposited satisfactorily.

Abstract: The device has a base element (1) and a wing (5) arranged so as to be pivotable on the latter with a swivel joint (3). The swivel joint (3) has two fastening flanges (9, 10) which are pivotable about the swiveling axis (7) for fastening on the base element (1) or on the wing (5). At least one of the fastening flanges (9) has a snap on first holding element (21b, 23a) and second holding elements interacting with the first at least on one of the free rim sides of the base element (1) and/or of the wing provided for fastening the swivel joint. With these holding elements, the fastening flange is permanently connectable with the long side of the base element (1) and/or wing following the following fastening by pressing together.

Abstract: In order to accommodate a relatively large number of paper storage reels (11-17) with diameters of relatively large size in correspondence with a relatively large paper reservoir in a space of relatively small dimensions, storage reels (12-15) are also arranged in side-by-side relationship, i.e. laterally offset with respect to the paper feed slots (21-27) of the printer (20). The path segments of the paper webs (2-5) extending in this case in part skewed with respect to the paper feeding direction of the printer are made possible by rerouting members (52/62, 53/63, 54/64, 55/65, 42-45) at which the paper webs are guided on a rerouting path extending along part of a helical winding.

Abstract: A coin feed opening (16) formed in the lid (1) of the coin collection box is associated with a closure with a closing slide (17) displaceble by means of a moving mechanism (49, 45, 46) operable on the outside of the coin collection box. An escapement (29-32) designed as a jump mechanism makes possible, after every closing of a lock (6) securing the lid (1) against unauthorized opening, only a one-time opening and subsequent closing of the closure. Once the coin collection box is in the automat in its predetermined position, a catch (57, 59) blocking the closure in the opening direction (28) is released by a bolt (53) fixedly connected to the automat. At the same time, the bolt (53) is locked by means of a latch (58) in the coin collection box when the closing slide (17) is in the open position.

Abstract: The compartments (3) of a compartment ring (1) rotatable stepwise about its horizontal axis (2) are bounded at the ring end faces by circular-ring walls (6, 7), at the outer ring circumference by a cylindrical annular wall (19) exhibiting at the top an inlet opening (23) leading into respectively one compartment (3a), and at the inner ring circumference by a conical annular wall (20) exhibiting at the top an outlet opening (24) offset with respect to the inlet opening (23) in a direction of rotation (17) of the ring, this outlet opening leading into a coin return channel (26) and into a coin overflow channel (27). Upon rotation of the ring in this direction (17), the last-received coins drop into the coin return channel (26). Upon rotation in the opposite direction (18), respectively one coin is received while another coin, exceeding the capacity of the compartment ring (1), drops into the coin overflow channel (27).

Abstract: Several guide channels (6, 7) for respectively one paper web are arranged in a fan shape, these channels being oriented toward the nip (5) of a pair of feed rolls (1) of a printing device (2, 3) and each being equipped with a gripper (8, 9). In the rest position, each gripper (8, 9) is in contact with a web of paper, and the free ends of the paper webs have a spacing from the nip (5). The gripper (9) for the paper web to be printed advances the latter until it has entered the nip (5) of the rotating pair of rolls (1), then releases the web, and initially remains in its position (8). The pair of rolls (1) further conveys the paper web first into its printing position, after the printing step into its cutting position, and after cutting again in the reverse direction.

Abstract: The matrix head (1) of a matrix printer is guided close to the printing site (2) on a round bar (7) by means of profiled rollers (8) absorbing the reactive force during printing and being fixedly mounted at the matrix head (1) and by means of guide rollers (9) absorbing the force of gravity of the matrix head (1) and being resiliently mounted at this head, and is slidingly guided, at the head end facing away from the printing site (2), on a rail (15). A cord drive serves for displacing the matrix head (1), this cord drive comprising a cord (31, 32, 33, 34, 35) guided over a cord pulley (17) at the matrix head (1) and over further cord pulleys (19, 23, 24) and over a driving pulley (26), the ends (29, 30) of this cord being fixedly attached beside the ends of the round bar (7). Thereby the matrix printer can be constructed in a compact and lightweight fashion and can be operated with accuracy even in case of strong vibrations.

Abstract: In a matrix printer, the knife blade (27) of the cutting device for the imprinted paper is integral with a cam carrier of a planar sliding cam drive roller (3) supported on the matrix printing head (1). Three cam sections (41, 42, 43) on the cam carrier are contacted by the drive roller (3) as it moves back and forth with the matrix printing head (1) during printing, and the drive roller contacting one of the cam sections (42) to move the knife blade laterally of the imprinted paper to cut it as it leaves the printing site, and contacting another of the cam sections (43) to return the knife blade to its retracted position.
