A known device for increasing the functional reliability for a hydraulic circuit of a hydraulic clutch having a pressure reservoir (25) and a release cylinder (5) which comprises a primary piston (14) and a secondary piston (16). A compensation volume is developed in the sense that when the vehicle is at a standstill and the parking brake released, an unintentional release of the clutch is prevented. A pressure-monitoring / pressure-supply device (28) is used for determining a reference operating pressure and establishes a static pressure which, in case of any system error, only allows displacement of the secondary piston (16) such that the contact pressure of the clutch discs, against one another, is still sufficient to maintain the vehicle at a standstill.

The invention relates to a hedge trimmer 1, having a blade arrangement 9 with at least one cutter bar (11, 12). The utter bar (11, 12) is driven in a reciprocating manner by the drive motor via the gear mechanism 30 in a longitudinal direction. The blade arrangement includes a guide mechanism (10, 10') that extends over at least a part of the length of the cutter bar (11, 12). The cutter bar (11, 12) is longitudinally movably held on the guide mechanism (10, 10'). The guide mechanism (10, 10') is embodied as a molded part that includes a generally flat fastening portion 76 and a profiled guide portion 77. The cutter bar (11, 12) is supported on the guide portion 77, to achieve a high intensity when the weight is lighter.

Provided is a friction-type damper device. The friction-type damper device mainly comprises a cover plate, an outer shell, a transfer element, a friction head, a friction disc, two bearings, a spring, a telescopic shaft and a rotating shaft. The rotating shaft and the cover plate are fixed onto connecting rods on the two sides of a joint capable of providing resisting moment correspondingly, the rotating shaft is fixedly connected with one connecting rod, and the cover plate is fixedly connected with the other connecting rod; the cover plate and the friction disc are oppositely arranged and fixedly connected together through the outer shell; the rotating shaft penetrates through a circular hole in the center of the transfer element and is fixedly connected with the transfer element, and the rotating shaft and the transfer element are together arranged between the cover plate and the friction disc; the telescopic shaft penetrates through the portion, around the rotating shaft, of the transfer element, the friction head is arranged at the top of the telescopic shaft, and the friction head abuts against the friction disc; and the rotating shaft is connected with the cover plate through one bearing, and the other end of the rotating shaft is connected with the outer shell through the other bearing located at the center of the friction disc. According to the friction-type damper device, the resisting moment of the damper has nothing to do with the rotating speed or the external force and is only related to the absolute rotation angle where the device is located, and the blank of the friction-type damper is filled in.

A bellows having a substructure including a first end and a second end, the ends being movable relative to one another, circumferential bulges, which are spaced apart by first constricted regions, being formed in the substructure between the ends, and a second constricted region being formed in at least one bulge. The width of the second constricted region corresponds at least to its height in order to reduce the axial stiffness and increase the radial stiffness.

The invention relates to a method for regulating a drag torque of a motor vehicle driven by an electric motor, wherein a regulating device influences the drag torque with a corresponding change in the position of the accelerator pedal, wherein a sensor device senses a tire on a roadway surface on which the motor vehicle is present and provides the information to a computer, wherein the computer prompts the regulating device to adjust the drag torque as a function of the friction coefficient. The invention further relates to a device having means suitable for carrying out such a method.

A method for producing a printed product in which a complete content of the printed product is printed sequentially in series on one or both sides along a paper web having a width based on a multiple of a width of a finished printed product, including cutting the paper web in a direction crosswise to a longitudinal direction of the paper web to produce a cut-off section having a length based on a multiple of a length of the finished printed product, folding the cut-off section at least once in the crosswise direction in a location based on the length of the finished product, and cutting one of the folded cut-off section subsequent to the folding or the paper web prior to the crosswise cutting, to form a plurality of partial webs each having a width based on the width of the finished printed product.

An adjustment system for a motor vehicle seat connected with two rails and shiftable with the two rails is provided. The adjustment system comprises a holding element made of plastics, which is arranged between the two rails, and a reinforcement element which is connected with the holding element.

A hydraulic system for a clutch has a pump conveying a hydraulic fluid stream via a heat exchanger to a controllable hydraulic valve which divides the hydraulic fluid stream into a first part stream and a second part stream. The first part stream flows to a reservoir via friction linings of the clutch and the second part stream flows to the reservoir via a hydraulic path bypassing the friction linings. The hydraulic system is set up for upgrading a cooling of the clutch by increasing the first part stream at the expense of the second part stream and for reducing the cooling of the clutch by increasing the second part stream. The system is set up for temporarily upgrading the cooling of the clutch in the event of a changeover of torque transfer from transfer via a first part transmission to transfer via a second part transmission of the transmission.
