Title: Method for fixing components
Inventor: GFELLER MARTIN
IPC: H05K13/04
Filed: 1993-05-13
Abstract: In the case of a method for temporary mutual fixing of components (1, 2, 4, 5) until a permanent connection process, provision is made to introduce a liquid (9, 10, 11) and produce a liquid film (9A, 10A, 11A) between the plane surfaces of the components (1, 2, 4, 5). Adhesion between the components (1, 2, 4, 5) is enhanced by such a liquid film (9A, 10A, 11A). In the actual connection process, for example soldering, the components (1, 2, 3, 4, 5) are heated so that the liquid films (9A, 10A, 11A) evaporate. In order to make it possible to sustain higher forces, the liquid films (9A, 10A, 11A) may additionally be cooled until their aggregation state changes and they become solid. This produces a simple, cost-effective method by means of which components (1, 2, 4, 5) can be mutually fixed securely, without stress and therefore without risk of damage. <IMAGE>

Title: Continuous process for the deep-penetration improvement of soils by means of a bucket wheel
Inventor: DREBENSTEDT CARSTEN DR ING
IPC: A01B79/00
Filed: 1993-05-12
Abstract: The invention relates to a continuous process for the improvement of soils by means of an appliance having a bucket wheel, in particular a bucket-wheel excavator, which, with minimal soil movement, mixes a soil-improving substrate to the depth necessary for deep-rooting plants, simultaneously loosens and aerates the soil and thereby increases the soil fertility. This is achieved, according to the invention, in that the necessary substrate is applied to the soil to be improved, and the substrate and soil are picked up in the appropriate thickness by means of buckets, intermixed and thrown off in front of the cutting circle of the bucket wheel via a conveyor belt arranged laterally relative to the bucket wheel and running in the clockwise direction.

Title: Method and device for adjusting the angular position of a cam shaft
Inventor: MEYER KLAUS-GERD DIPL ING
IPC: F02D13/02
Filed: 1994-03-12
Abstract: A method is disclosed in which the following procedure is adopted to adjust the angular position of a cam shaft in relation to the rotational angle of a crank shaft to a desired angular position with the aid of an actuator element which is driven with a control signal by a control device operating by running through a control program:   - the actuator element can be driven with in each case one of three values of the control signal; - the adjustment speed (V_ESTIM) of the cam shaft which will be present at the start of the following program run is estimated; - a specific adjustment angle ( alpha _ESTIM+) is estimated from this adjustment speed and the known timing characteristic (c, v_END) for the cam shaft adjustment after the switching over to the control signal from the holding value; and - the system then switches over from the early value or late value of the control signal to its holding value even if the deviation between the adjustment angle ( alpha _ESTIM+) and the desired angular position lies within a tolerance margin.   With this method and a device which operates according to it it is possible to adjust the angular position of the cam shaft in a quick and stable way. <IMAGE>
