Patent DE-3338881-A1 (DE)
Title: Mast rail (tracker)
Inventor: FLEMMING JOERG
IPC: B63B35/79
Filed: 1983-10-24
Abstract: The construction enables the position of the mast foot to be changed in the longitudinal direction during sailing and enables a defined safety release feature to be obtained. Particular achievements are that there is the least possible risk of silting-up, fixed-point operation at the rail end, and release not only under tensile loading but even during moment stressing. These objects are constructively achieved by clamping the mast-foot slide by means of movable guide surfaces of the mast slide. The adjusting mechanism is accommodated in the sealed-off inner space of the rail. Depending on the selected design of the operating lever (rotary or axial movement), the compression force of a spring is converted into the clamping action by wedge or eccentric systems. Operation is effected in two stages. In the first stage, the guide surfaces are drawn together precisely to such an extent that axial displacement is possible but vertical release still does not take place. In the second stage, the guide surfaces are fully drawn together so that the slide can be removed.

Patent DE-3345026-A1 (DE)
Title: Circuit for outputting pulse powers
Inventor: RAUSCHER GUENTER DIPL ING
IPC: H03K3/57
Filed: 1983-12-13
Abstract: The invention relates to a circuit for outputting pulse powers having a determinable pulse frequency to electric or electronic loads (2) with a permanent load-carrying capability which is low compared with the pulse power. To ensure reliable operation and at the same time to protect the load against overloading, it is proposed to supply the load via a constant current source (1) which charges a capacitor (3), the charge of which is discharged in the form of pulses via the load with the aid of a control circuit (5). During this process, the constant current source (1) outputs at the most a current which is within the range of the permanent load current which can be tolerated by the load. The capacitance of the capacitor (3) is dimensioned in such a manner that the load is not destroyed if the total charge of the capacitor is discharged at once across the load. <IMAGE>

Title: Delivery mechanism for product in block form
Inventor: TISCHER SIEGMAR
IPC: B42C19/08
Filed: 1984-01-23
Abstract: The invention relates to a delivery mechanism for product in block form, and is preferably used to produce a shingle of book blocks in book production machines, especially at high cycle speeds. The object of the invention is, by avoiding abrupt forces acting on the book block by contrast with conventional delivery mechanisms, to reduce the wear occurring at high working speeds and the noise caused thereby. In order to form shingles at high cycle speeds, the object is to achieve a superimposition of movement which is necessary in both vertical and horizontal directions for the block pusher with a low impact speed on the book block and a drive mechanism which produces little wear. This object is achieved, according to the invention, in that the block pusher is fixed to a coupled drive to be capable of rotary movement and is connected to a cam gear, preferably consisting of a cam disc, a cam roller and a plurality of rocking levers which, via connecting rods, effect a vertical displacement of the block pusher.

Title: Abrasive-belt grinding machine, in particular wide-abrasive-belt grinding machine, for the wood-working industry
IPC: B24B21/18
Filed: 1984-03-09
Abstract: During grinding with an abrasive-belt grinding machine, in particular a wide-abrasive-belt grinding machine, endless abrasive belts of different grain sizes, and therefore of different thicknesses, are used. When changing from a thicker abrasive belt to a thinner one, that is when fine grinding after the preceding rough grinding, the lower deflection roll (1) is moved, by means of a simple device, towards the bearing surface (8) for the workpiece (7) by the amount constituted by the difference in thickness of the abrasive belt. Irrespective of the thickness of the endless abrasive belt (3), the grinding surface of each abrasive belt thus runs essentially tangentially to a grinding plane (19) which is, as it were, the zero position for determining the grinding depth of each abrasive belt. The lower deflection roll (1) is eccentrically (23) mounted, with the result that a rotation of this roll effects a lifting or lowering action with respect to the grinding plane (19). In the case of an adjusting device (30) comprising a toothed gear rim (24) and a toothed rack (26), if appropriate with the interposition of a pinion, the angle of rotation is determined by an adjustable stop which is designed according to the invention as a multiple stop (3). The latter possesses a plurality of stop elements (32) which may be brought into the operating position, the stop faces (35) of said elements in the operating position being in each case a different distance from the slide (29), located in its initial position, or from the stop counter-face (41) of said slide ...

Title: Self-locking automatic coupling device
Inventor: KLEBER MAX
IPC: A01B71/06
Filed: 1984-08-22
Abstract: Self-locking automatic coupling device. The invention serves for the automatic coupling of cardan shafts which are arranged for power transmission on working appliances attached to the rear and/or front of the tractor. Since the cardan-joint head is always parallel both to the ground and to the drive shaft of the working appliance in any high, low and at the same time lateral position, the coupling device can also be used in conjunction with tractors, of which the power take-off shaft output is not axial, thus, for example, also lateral. Since the driver need not leave the tractor, he is exposed to less risk of accidents.

IPC: F01D21/16
Filed: 1985-01-03
Abstract: A closing device for switching off the supply of flow medium to a turbine is actuated by means of a servomotor (M) constructed as an asynchronous motor. In the case of safety shut-offs of the current generation system, for example in the event of mains failure, the servomotor (M) is fed with rotary current which is output by the asynchronous generator (G) as the rotating masses run down. A compensation capacitor (C1) is continuously connected to the asynchronous generator (G). A special energy accumulator for the actuation of the servomotor (M) is not necessary since the kinetic energy of the rotating masses is utilised for the actuation of the servomotor (M). <IMAGE>

Patent DE-3508447-A1 (DE)
Inventor: HILDENBRAND PETER
IPC: B60L3/10
Filed: 1985-03-09
Abstract: The invention proposes to superimpose on the reference setpoint for an electric vehicle drive an identification signal (I), an alternating torque (Mw) being superimposed on the running torque (MB) produced by a motor (9). The reaction of the mechanical system (10) to this excitation is detected, e.g. using a tachogenerator (11), at a suitable point in the mechanical driving system (10), e.g. at the motor shaft (W) or at the driving wheel (R). The tachogenerator (11) emits an alternating voltage (20), from which a measurement signal (S) is obtained by filtering. This signal is compared to the identification signal (I) fed into the driving system, e.g. with the aid of a correlation calculation. By evaluating the result of the correlation calculation, it is possible to establish whether a swerving or sliding condition is present. <IMAGE>

Title: Device for the infinitely variable adjustment of the valve timings of exhaust and refill valves
Inventor: SCHREIBER KLAUS-HAGEN
IPC: F01L1/348
Filed: 1985-03-14
Abstract: The device for the infinitely variable adjustment of the valve timings of exhaust and refill valves of reciprocating piston internal combustion engines has at least one camshaft, driven by the crankshaft by way of a toothed belt drive, for operating the exhaust and refill valves and tensioning elements (6 to 8), acting on the toothed belt (5) and essentially adjustable perpendicular to this, for producing a phase displacement between the crankshaft and the camshaft. In order to achieve adjustment of the valve timings of the inlet and exhaust valves variable within wide limits and independently of one another, it is proposed that two camshafts be provided for separate operation of the inlet and exhaust valves in a known manner and that the tensioning elements (6 to 8), for acting on the toothed belt (5) be arranged both between the crankshaft and the two camshafts and between the two camshafts themselves. At the same time it is advisable for the tensioning elements to be adjustable separately from one another by means of an auxiliary force, for example hydraulically. <IMAGE>
