Patent DE-3600208-C1 (DE)
Title: Method for desoldering electronic components, and a device for carrying out the method
Inventor: HADERLAPP ALFRED
IPC: B23K1/018
Filed: 1986-01-07
Granted: 1987-02-26
Abstract: A method for desoldering electronic components such as capacitors, resistors or the like is indicated, as well as a device for carrying out the method. In this case, a suction braided cable is placed over those solder points between the component and the board which prevent any relative movement between the component and the board, the suction braided cable additionally at least partially covering parts of the component, such as contact tabs or the like, which are remote from the solder points. The suction braided cable is then heated essentially in its entire region covering the solder points and the parts of the component remote from the solder points to the temperature at which the solder melts. After reaching the temperature at which the solder melts, the supply of heat is terminated, and the component is finally lifted off the board, together with the suction braided cable.

Granted: 1987-07-30
Abstract: A filter arrangement for supplying rooms with dust-free air in laminar flow is described. The filter arrangement consists of juxtaposed filter elements, each consisting of the filter element (1) and a frame (2) surrounding the latter. To illuminate the room, use is made of light sources (5), preferably located outside the region of the laminar air flow, and reflectors (7) on the underside of the frames, which are illuminated by the light sources and direct the light into the room in desired directions. The reflectors are designed such that they not only do not impair the laminar air flow, but even promote the laminarity. <IMAGE>

Title: Punching device for the production of ceramic tiles
Inventor: KECK DIETER
IPC: B28B11/16
Filed: 1987-02-18
Granted: 1988-03-10
Abstract: A punching device for the production of ceramic tiles from a clay profile consists of a punching die with punching knives, which is arranged on a punching base which moves back and forth and travels intermittently synchronously with the clay profile. The punching knives for punching the tiles are divided into 4 individual punching knives for punching out the individual lateral edges of the tiles, the punching knives being arranged separately from one another. 2 punching knives in each case are arranged in pairs and at the distance of the tile width from one another, 2 of the punching knives being arranged parallel to and the other 2 punching knives transversely to the travel direction of the clay profile, adjacent to one another as individual punching assemblies. During the synchronous travel of the punching base with the clay profile, a punching knife of one punching assembly with a punching knife of the other punching assembly punches 2 lateral edges of the tiles simultaneously, whereas the 2 other punching knives of the punching assembly then simultaneously punch the two other lateral edges of the tile.
Patent DE-3705170-C1 (DE)
Inventor: HEUSSER MARTIN DIPL-ING
IPC: F15B11/05
Filed: 1987-02-18
Granted: 1988-08-18
Abstract: In hydraulic control devices comprising a two-way flow regulator in a reservoir return passage, in which the flow regulator comprises a metering restriction and a pressure equalizer including a control piston with the piston ends disposed in control chambers and subjected to the action of control pressures, the actuation of a single-acting hydraulic motor under load often results in an unavoidable switching shock, because the displacement of the control piston involves the consumption of a certain volume of the pressure fluid. In order to eliminate the switching shock with a simple construction, the end of the control piston subjected to the action of the load pressure is formed as a closure element cooperating with a valve seat in the manner of a poppet valve for holding the load pressure.

Title: Method for detecting objects in a monitoring area
Inventor: RUCKH RAINER DR RER NAT
IPC: G01S17/04
Filed: 1994-02-19
Granted: 1995-02-16
Abstract: The invention relates to a process for detecting objects in or entering a region to be monitored in which a device with at least one transmitter, at least one receiver and an evaluation unit is used for monitoring. A beam emitted by the transmitter is guided within the region transversely to the direction of radiation of the transmitted beam. The distances between the objects and the device are found by means of the transmitted beam for various orientations of the transmitted beam and these position measurement values are stored in the evaluation unit. According to the invention, to detect objects (2) with a given outline, the position measurement values for the object (2) concerned are compared with references which are calculated in the evaluation unit (20) from the outline of the object (2) in a predetermined position in the region (10) to be monitored. An object (2) with the given outline is regarded as recognised if a minimum number N of the position measurement values lies within at least one tolerance band T around the reference values. The minimum number N of the position measurement values and the width of the tolerance band T are selected in the evaluation unit (20) dependently upon the dispersion of the position measurement values.
