Abstract: The invention concerns an arrangement for the movement of a working unit of an agricultural working implement between a first position and a second position, with an actuator that is provided with a chamber to which a pressurized medium can be applied and that is coupled to the working unit in such a way that it brings the working unit into the second position when the medium is applied to the chamber and the working unit reaches the first position when the medium is not applied to the chamber. An accumulator control arrangement serves to connect the chamber of the actuator to the accumulator only when the working unit moves into the first position.

Abstract: A multiple-key unit is provided that includes a top portion, a base portion and a support mechanism. The support mechanism is provided with a body portion and a substantially U-shaped wire. The U-shaped wire includes a cross-part and two free ends that are inwardly bent and are parallel to the cross-part of the wire. The cross-part of the U-shaped wire is rotatably supported in a bearing in an eccentric manner at the key top and is parallel to the central, longitudinal axis of the key top. An assembly stop extends from the bearing and maintains the U-shaped wire, during assembly, in an oblique assembly position. Moreover, wire guides are provided in the cross-sides of the key base to vertically receive the free ends of the U-shaped wire during assembly, and in which wire guides the free ends are horizontally displaceable when the key is actuated.

Abstract: A lever projects into the space between two guide plates for a sheet data carrier and is journalled so as to upwardly pivotable in the transport direction of the carrier against the force of a spring. A Hall-element sensor is secured adjacent to a magnet secured to the journalled end of the lever so that the sensor is activated by translation or rotation of the lever effected by engagement of the lever with the feeding of the data carrier. The lever is arranged to initially translate to activate the sensor and rotated after the translation so that when the lever is returned to its position prior to translation, only rotation of the lever switches the state of the sensor to indicate the position of the trailing edge of the carrier.

Abstract: An inking system of postage and valuation stamping machines has an inking unit with an ink chamber and a portion covering the ink chamber. An inking unit cover has a stepped shape and a drip edge at a step thereof with a wedge-shaped cross section. The inking unit cover has a funnel disposed on the portion of the inking system covering the ink chamber for refilling the ink chamber with stamp ink. A stamp ink container is provided in the form of a cartridge. The funnel guides, retains and empties the cartridge.

Abstract: A copy holder apparatus for use in combination with a conventional typewriter is set forth. The apparatus includes a generally "S" shaped transparent bracket with a lower leg defining a slot to accept a typewriter table in a conventional typewriter. The upstanding leg of the apparatus includes a spring clip cooperative with an outer face of leg for securement of documents to be copied. A fiber optic cursor is vertically positionable along the upstanding leg to indicate and accent lines to be copied by an operator. The upstanding leg is angulated at approximately thirty degrees relative to the lower leg to orient the document to be copied relative to an operator.

Abstract: An article of manufacture is provided which includes a molded piece-part having a substantially rectangularly-shaped plate portion including opposed surfaces. The piece-part also includes a pair of elongate parallel-spaced rack gear portions depending from one of the surfaces of the plate portion. The article further includes a member made of a resilient material having an inner surface facing the other of the surfaces of the plate portion and fixedly attached thereto. Moreover, the member includes a plurality of intersecting channels extending into the member from the inner surface thereof.

Abstract: Printer for data processing system, the printer being for installation on a working desk, and comprising a multifunctional stand having a generic handle-form member hinged to the printer body near the edge defined by the base and the rear wall, the stand being pivotable to take a non operative position close to the base or the rear wall and at least one an operative position in which the stand is positioned below and apart from the base and supports the rear portion of the printer in a position spaced apart from the working desk.
