Abstract: A fastening arrangement for a movable part especially a folding top or a roof of a motor vehicle. The arrangement includes a rotary latch which serves for securing a fastening pin of the movable part and is rotatable by means of an actuating device for a blocking and release of the fastening pin which can be retained by means of a detent pawl. In the locked position of the fastening, the detent pawl rests in an undercut principal notch of the rotary latch. High frictional forces and disturbing noises therefore are avoided during the unlocking operation. The rotary latch is rotatable through a specific angle oppositely to the blocking direction of the detent pawl by means of a control device activatable by the actuating device.

Abstract: A method and device for the electrical control of a central locking system and of a mechanical securing device (that provides additional lock protection) for motor vehicles by a lock cylinder that interacts with at least two control switches. This method and device ensures a better utilization of the electrical control switches, in that, an unlocking control switch assigned to the unlocking of the central locking system and the deactivation of the mechanical securing device is switched in addition to a locking control switch assigned to the locking of the central locking system. If the lock cylinder is pivoted in the locking direction beyond its regular locking position, the resultant joint switching state of the two switching control devices is evaluated to activate the mechanical securing device.

Abstract: In an arrangement of a differential for driving two vehicle wheels, with an outer casing and a gearbox casing supported by a bearing. Provided on the gearbox casing is an annular face which is concentric in relation to the bearing axis and with which a solid of revolution made of an elastomer material and held on the outer casing is in continuous, concomitantly rotating contact with a small contact pressure.

Abstract: A transformer unit mountable above the cutting deck of a mid-size, walk behind rotary mower, converts the mower into a riding mower. The transformer unit allows an operator to sit above the cutting deck and use the original operator control handle, which is relocated to the front end of the mower. The transformer unit comprises a support frame affixed to a cutting deck support structure. The support frame includes a vertically tiltable floor unit that extends over the top of cutting deck. An auxiliary operator control handle attachment fixture is mounted to the forward end of the support frame adjacent to the front end of the mower. A set of auxiliary control links is retained by the support frame for reconnecting control elements of the repositioned operator control handle with mower drive and steering components. An operator seat fixture is mounted to a rear end of the tiltable floor unit of the support frame.

Abstract: A method and apparatus is provided for automatic shifting of a multi-path, toothed-wheel gear change box with at least two gearbox subunits in parallel to one another in the power transmission path between an input shaft and an output shaft and having loose wheels which can be coupled to their shaft in each case by a gearwheel clutch. A starting shift condition is selected if the vehicle is at a standstill, in which condition both the gearwheel clutch connected to the loose wheel of the gearwheel stage of the reverse gear and the gearwheel clutch of that gearwheel stage which forms the lowest of the gears, which are independent of the power-shift clutch of the gearbox subunit with the gearwheel stage of the reverse gear, are engaged.

Abstract: A method for detecting the motion and position state of a component of an inductive electric load. The component can be moved between two end positions by magnetic interaction, in which the total waveform of the drive current is divided into a plurality of states. By evaluating these individual states, comprehensive error diagnostics and a setting of operating parameters of the inductive electric load to operating conditions are possible.

Abstract: A paper tray arrangement is disclosed for receiving a stack of paper and which is insertable into a receiving device of a copying machine or the like and which includes a supporting plate for the stack of paper and springs applied to the supporting plate to lift the supporting plate off the bottom of the tray. Tensioning apparatus is provided for the springs and a stop of the receiving device is assigned to the tensioning device in such a manner that the spring is tensioned when the paper tray is inserted into the receiving device and is relaxed when the paper tray is taken out of the receiving device.

Abstract: A flame-type heater plug for an internal combustion engine includes a plug housing having a proportioning insert for the fuel supply, a heater bar secured at one end in the plug housing with a free end extending outwardly of the plug housing, and an evaporation tube extending along a substantial length of the plug housing from the proportioning insert and surrounding the heating bar to form an annular interspace therebetween. The free end of the heater bar extends from the evaporator tube and is surrounded by a flame tube including passage orifices for passage of intake air into the interior of the flame tube. A helical swirl channel on the outer surface of the heating bar in the plug housing forms a fuel connection between the proportioning insert and the evaporator tube opening into the annular interspace. The passage orifices may be provided with deflectors to prevent direct contact of the heating bar by the air flowing therethrough.

Abstract: The equipment system consists essentially of the undercarriage 101 having supporting wheels, the rotary device with dovetailing prongs 102, the sowing machine 103 and the land roller or clod breaker apparatus 104. The system components may be used in various combinations or individually.

Abstract: A process treats the waste water which accumulates as used activation solution in the one-step activation, on the basis of acidic palladium/tin solutions, of large-surface plastic substrates, in particular of non-woven fabric, needled felt or open-pored foam sheets, for the purpose of a subsequent chemical metallization. A concentrate composed of palladium chloride and sodium chloride and then a solid tin salt in a molar ratio of 1:1.5 to 1:4, based on the palladium, is added to the waste water. After a certain maturing time, a ready-to-use activation solution is again obtained for activating a plastic substrate and reduces the amount of the waste water hitherto accumulating after the activation has taken place.
