Title: Double-pivoted re-ripping stage
IPC: E21D9/12
Filed: 1988-11-17
Abstract: For re-ripping work in roadways in underground mining, re-ripping stages are used which can be moved on the rail of the monorail conveyor via their heavy-duty beam and allocated transport trolleys. Via a parallelogram guide-bar linkage, a working platform is secured to the heavy-duty beam in a liftable and lowerable manner, optimum slewing and pivoting capacity for the working platform or the entire re-ripping stage being provided by the allocation of one ball-bearing slewing rim each in the connecting area between the parallelogram guide bar and the heavy-duty beam and between the parallelogram guide bar or the stop bracket and the working platform. In addition, the ball-bearing slewing rim allocated to the heavy-duty beam, with parallelogram guide bars and working platform, is allocated to a heavy-duty carriage which is displaceably arranged in the longitudinal direction of the heavy-duty beam. This provides on the whole for a re-ripping stage via which the brushing tunnel arranged in the roadway section not yet re-ripped can in each case also be put into the new working position or be appropriately directed. In addition, since the stop bracket acts on the working platform from below via the ball-bearing slewing rim, an optimum base is also provided for. <IMAGE>

Patent DE-3918254-A1 (DE)
Title: Method for preventing load cycle shocks
Inventor: HAACK REINHOLD DIPL ING
IPC: F16D48/02
Filed: 1989-06-05
Abstract: A method is described for preventing load cycle shocks due to abrupt changes of the accelerator pedal position in motor vehicles, especially passenger motor vehicles, which are equipped with an internal combustion engine (1), a transmission (5) and a clutch (3), arranged between the internal combustion engine and the transmission and controllable in respect of its transmittable torque. In order to prevent the load shocks when the accelerator pedal (12) is adjusted from an overrun position into a load position, it is proposed that the clutch (3) be automatically forced out of an engaged position assigned to the overrun position of the accelerator pedal, with a predefinable slip between the speed of the internal combustion engine (1, 2) and of the transmission input (4), in the engaging direction for the transmission of a continuously increasing torque. In the case of an adjustment of the accelerator pedal (12) from a load position into an overrun position on the other hand, it is proposed that the clutch (3) automatically be fully disengaged first before the internal combustion engine (1) changes from traction into overrun conditions and then actuated in the engaging direction again until a predefinable slip is attained between the speed of the internal combustion engine (1, 2) and that of the transmission input (4). <IMAGE>

Patent DE-3935738-A1 (DE)
Inventor: FORSSMANN WOLF-GEORG PROF DR M
IPC: A61K38/00
Filed: 1989-10-27
Abstract: A human blood peptide, hPTH (1-37), the structure of which has been elucidated, can be used as a drug for diagnostic, medical and industrial purposes. The isolation of an hPTH (38-84) fragment demonstrates the existence of the hPTH (1-37). Removal of amino-terminal amino acids on the hPTH  (1-37) reduces its biological activity. The hPTH (1-37) which circulates in the blood is identical to the synthetic reference substance hPTH (1-37), but not fragments such as hPTH (1-33), hPTH (1-34) or hPTH (1-38). The existence of the hPTH (1-37) molecular form was proved by mass spectroscopy (plasma desorption method). A different biological activity and differences in the three-dimensional peptide structure between the hPTH (1-37) fragment and other hPTH fragments prove that this hPTH fragment is the preferred natural peptide of the parathormone family, which should be used for treating diseases of the parathyroids, the circulatory and respiratory systems, the male genital organ and the kidneys.

IPC: G02B26/10
Filed: 1989-11-30
Abstract: An optical positioning system for at least two pixels (B1, B2) comprises a wavelength-dispersive, first light-deflecting element (2) which deflects light beams in a first deflection direction in function of their wavelength. For faster positioning, the optical system has a narrow-band light source (1, 1a) of controllable wavelength for each pixel. The first light-deflecting element (2) is arranged in the optical path of a second light-deflecting element (3) for effecting an additional deflection which is essentially independent of the wavelength. The range of deflection of the first light-deflecting element (2) is much smaller than that of the second light-deflecting element (3). The beams from the light sources (1, 1a) strike the wavelength-dispersive element (2) together. The wavelength of the light source (1 or 1a) can be adjusted so that all the pixels (Bi) obtain simultaneously a desired pixel position in the range of deflection of the second light-deflecting element (3) around the basic position determined by the latter.
