Patent DE-3832469-A1 (DE)
Title: Crimping press
Inventor: GERST MICHAEL
IPC: H01R43/048
Filed: 1988-09-23
Abstract: A press ram (10) can be moved in drive terms by a motor (12) via a drive rod (16) and a hinged rod (14), one end of the drive rod (16) being connected to the central pivoting point (24) (fulcrum) of the hinged rod. The other end of the drive rod (16) is eccentrically connected to a wheel (68) which can be rotated by the spindle (62) of the motor (12). The motor (12) can be pushed away from the rod (14) against the influence of a flexible buffer (84), it being possible to set the flexibility of the buffer (84) by means of a sliding piece (100). When the ram (10) exerts a compression force via a crimping stamp (20) on a crimping ferrule (F), an axial force component is exerted on the rod (16), as a result of which the motor (12) is forced back against the buffer (84) in order to damp the compression force exerted on the ferrule (F) to an extent which is defined by the setting of the sliding piece (100). The closing level of the press can likewise be constructed to be adjustable, to be precise by means of an arrangement composed of a wedge (52) and a sliding piece (32). <IMAGE>

Patent DE-3835406-A1 (DE)
Inventor: RISSKOV CAI
IPC: G01F23/296
Filed: 1988-10-18
Abstract: A state of fill-determining apparatus comprising a transmitter and receiver arrangement (3) for sound pulses, which sound pulses are, in use, reflected at the surface (4) of the filling medium (1) and at a reference reflector (14) and from the there-and-back transit time of which the state of fill is determined. The transmitter and receiving arrangement (3) comprises a bi-directional electro-acoustic transducer (9) of which, in use, the oscillations die away within a predetermined time period after excitation by a reflected sound pulse or an electrical transmit signal. To prevent the state of fill from exceeding an upper limiting value an additional state of fill sensor (23) is arranged to respond to the attainment of a predetermined state of fill at which the spacing of the surface of the filling medium (1) from the bi-directional electro-acoustic transducer (3) has approximated to a distance which would be traversed twice by a sound pulse during the predetermined time period. The sensor (23) may include electrodes (22) which sense electrical conductivity changes or other types of switching devices. <IMAGE>

IPC: G01M99/00
Filed: 1989-06-14
Abstract: The method and device for multivalent signal capture, processing and evaluation can be used for automated machine and system monitoring. The aim of the invention, while observing a minimum expenditure on devices, is to implement a maximum range of specific diagnostic tasks on machines and systems, to make expenditure on maintenance finally more effective. The object of the invention is to integrate various diagnostic methods in only one single method, without having to increase the expenditure on devices greatly, but to make many fields of use possible, and thus to implement technical diagnostic methods so that they can be called, on the basis of available basic circuit components. Two computers are linked to each other. According to the method, the way the object is achieved is that all the diagnostic algorithms and output data which are necessary for a diagnostic task are stored in the main computer A. By the transfer of the diagnostic algorithm which is relevant to the chosen diagnostic task, at least the signal capture part and the associated output data, to computer B, computer B's circuits are structured so that the corresponding signal paths are activated, i.e. modules of computer B are reversibly linked in a significant way by circuits, so that finally the specific program of the transferred diagnostic algorithm is completed.
