Patent DE-4313941-A1 (DE)
Title: Ground-working appliance
Inventor: GUETTLER FRITZ
IPC: A01B49/02
Filed: 1993-04-28
Abstract: Ground-working appliances, which are equipped with implements rolling on the ground and which are designed to be mounted onto a rear or a front lifting device of a tractor, do not, in many instances of use, satisfy the requirements demanded of them. In particular, they are inclined to become clogged when a working of ground covered with mulching plants is carried out. It is proposed to arrange the ground-working tines at an axial distance from one another and to arrange, in each case, one of the rolling implements, with its circumference facing forwards, so as to engage from the rear into the interspace between two adjacent tines. This design makes it possible to grasp plant parts or soil build-up caught between the tines and clear them out to the rear. The invention is used for appliances to be mounted on tractors. <IMAGE>

Title: A bottle packaging method and a bottle package
Inventor: LASKOWSKI SIGISMUND
IPC: B65D71/00
Filed: 1993-05-12
Abstract: The invention relates to a bottle packaging method and a bottle package, in which the package consists of a card or a comparable material in which the bottles to be packaged are held together securely for transportation by means of a package in which the anchoring tabs are located. The anchoring tabs are designed in such a way that, when the bottle neck with the projection has been introduced into the package, a permanent connection is provided between the bottle and the package, which is secured during transportation. The package is designed in such a way that each bottle is anchored individually in the upper region of the package by means of the anchoring tabs so as to be secure against dropping out, and that the stabilising of the package was carried out by means of the stabilising strips in the lower region of the package. The advantages of this invention are:     - up to 40 % less packaging material is used in this invention; - when some of the bottles are removed from the package, the remaining bottles remain packaged securely during transportation; - multiple use of the attachment piece is possible, e.g. when returning the empty products.   <IMAGE>

Patent DE-4344610-A1 (DE)
Title: Hydraulic control system
Inventor: LONNEMO KURT ROLAND
IPC: F15B13/02
Filed: 1993-12-27
Abstract: The system comprises a hydraulic actuator having opposed openings adapted to alternately function as inlets and outlets for moving the element of the actuator in opposite directions. There is a pump for supplying fluid to the actuator. There is also a directional valve comprising pilot operated meter-in valves to which the fluid from the pump is supplied through first lines for controlling the direction of movement of the actuator and a pilot operated meter-out valve associated with each opening of the actuator for controlling the flow out of the actuator. The pressure of fluid supplied to the actuator by the meter-in valve is sensed and supplied to a line extending from the output of the meter-in valve. A valve is provided in this line to provide a force selectively on the meter-in valve opposing the movement of the meter-in valve by the pilot pressure. The valve may comprise either a modulating valve or a shut-off valve.

Title: Device for controlling a window wiping system
Inventor: REIME GERD
IPC: G01N21/55
Filed: 1994-04-06
Abstract: In a device for controlling a window wiping system a sensor device (12) is provided which produces signals which are influenced by the window (10) being misted up or wet. A signal processing device (13) which is coupled to a drive motor (M) and sensor device (12) converts the signals (Es) produced by the sensor device (12) into control signals (S) for the drive motor (M). A specific position of the wiper during the wiping process is detected by a switch contact device (14). By virtue of the fact that when it is activated the switching contact device activates means for unloading a memory unit to which the signals produced by the sensor device (12) are fed, the control signals (S) being produced as a function of the value of the memory unit, and by virtue of the fact that as soon as the value exceeds a further prescribed value and/or after a predetermined number of successive wiping processes signal transmission means transmit further signals (Sw) to a background memory (25) whose contents also influence the production of control signals possibly even after the memory unit is unloaded, it is possible for a simple and cost-effective arrangement to be provided for using the detected signals to control a window wiping system which allows for peripheral conditions of use (Fig. 1). <IMAGE>

Filed: 1994-09-03
Abstract: The workpiece (50) is produced in a single mounting of a preformed blank by means of a tool (4) comprising at least one first and one second part (40,40',41). Its surfaces pointing radially outwards are produced by concentric rotation of all tool parts and the blank, while its surfaces pointing radially inwards are produced by rotation with gradually increasing eccentricity achieved by radial displacement of the first tool part (40,40') together with the blank relative to the tool part (41). By this displacement which is made possible by slidable mounting of the tool part (40,40') the blank is brought into engagement with the tool part (41). PREFERRED METHOD - Radial displacement of the tool part (40,40') together with the blank into an eccentric position takes place by means of a force acting against hydraulic or spring forces which preload the tool part and serve for restoring it into its original position. PREFERRED APPARATUS - At least one of the two tool spindles (2,3) is provided with an axially displaceable concentric adjustment cone (23,33) with surfaces (23', 33) which mate with the conical surfaces (42', 43') of the tool part (40,40).
