Title: Vertically adjustable trailer coupling for agricultural vehicles
Inventor: TEIBTNER ROLF
IPC: B60D1/46
Filed: 1988-05-13
Abstract: Trailer couplings, which can be vertically adjusted by means of a power-operated mechanism, on agricultural vehicles have hitherto required relatively complex guides with which it is however still not possible to adjust the coupling jaw to a desired degree. The new vertically adjustable trailer coupling is to be accordingly of simple design and provide a larger adjustment range for the coupling jaw. In order to achieve this object, in a vertically adjustable trailer coupling the parts of the power-operated mechanism (piston/cylinder arrangements (3)) supported on the vehicle side are fixed in relation to the vehicle and form the guide rails for the securing means (6) of the coupling jaw. In addition, the side parts (6a) of the securing means (6) of the coupling jaw are provided with vertical slots (6c) which face one another and along which a supporting plate (9) of the coupling jaw (10) is guided in a lockable fashion in a plurality of steps which are predetermined by catches. <IMAGE>

Title: Projection screen device for optical indoor firing ranges
Inventor: STECHEMESSER ERNST DIPL PHYS
IPC: F41J7/00
Filed: 1988-07-15
Abstract: The subject matter of the invention is a simple projection screen installation, of compact construction, having a paper web which is guided in duplicated or quadruplicated manner, or in more than a quadruplicated manner, as is illustrated in the figure, using an example. The paper web 1 is transported by the drive shaft 2, which is provided with a rough surface. The paper webs 1 are pressed closely together by the contact-pressure roller 3. The paper webs are deflected through the guide roller 9 by the contact-pressure rollers 8 on the floor of the room, and are passed back to the upper roller set 10. The drive support frame 13, which is fastened to the ceiling mounting frame 14 and, for its part, carries the telescopic frame 4, is pulled upwards by springs 16 and in consequence exerts a constant tensile stress on the paper webs 1. The telescopic frame 4 can be raised and lowered by means of the lifting and lowering device 12, in order to move the upper roller set into a favourable operating position close to the floor in order to carry out surfacing work. The projection screen installation can be varied in a versatile manner with respect to the arrangement of the drive roller 2, the number and guidance of the paper webs 1, and with respect to the design of the raising and lowering device 12. <IMAGE>

Patent DE-3827579-A1 (DE)
Title: Transmitter arrangement
Inventor: ESPRESTER RALF DR
IPC: H03F3/24
Filed: 1988-08-13
Abstract: In a transmitter arrangement with a transistorised transmitter amplifier, cooling problems occur especially when a particular rated power is always to be output with a load impedance fluctuating within a permissible VSWR range, for example due to frequency change or changed environmental conditions. The power dissipation can be kept uniformly low over the entire permissible impedance range by continuously measuring the instantaneous load impedance and controlling the supply voltage as a function of the measured impedance.

Patent DE-3831951-A1 (DE)
Title: Method of working mortar or concrete
IPC: C04B40/00
Filed: 1988-09-21
Abstract: When using the dry spray method for working mortar or concrete from a mixture of a hydraulic binder, primarily cement, with aggregate and water, adding a reactive synthetic resin miscible with water, the synthetic resin, possibly with water, emulsifies, is added to the premixed solid constituents of the mixture before feeding into the dry spraying machine and, for intimate distribution into the dry mix, is dry-mixed with the latter, then conveyed by the thin-stream method to a spray nozzle and mixed there with water. Since the moisture contained in the reactive resin is very small and the surface area of the constituents of the dry mixture is very large, the latter does not lose its characteristic nature to be conveyed like a dry mixture during the thin-stream conveyance, whereas during spraying at the nozzle as much water can be added as is necessary in order to make the mixture suitable for spraying with as little splashback as possible. <IMAGE>

Patent DE-3928724-A1 (DE)
Inventor: SOWIG HELMUT DIPL ING
IPC: H04N5/93
Filed: 1989-08-30
Abstract: The frame amplitude of the 16:9 frame size provided for high-definition television (HDTV) must be reduced for display on a 4:3 picture tube. This means that the upper and lower edges of the frame appear black and the contents of the frame previously suppressed by overwriting become visible. Future 4:3 TV sets will automatically switch to the reduced frame amplitude by means of identification data. Future video recorders will supply these data to the TV set during playback of a recording of a 16:9 format. As the frame contents are not overwritten, the switching of the video heads can be seen on the lower edge of the frame. The invention overcomes this drawback, because the emitted signal is scanned black in the signal path of the video recorder during change-over of the heads. Video recorders for reproducing a frame with a picture ratio of 16:9.

Filed: 1989-09-29
Abstract: The proposal is for a process for detecting irregular running in an internal combustion engine (10) in which a signal processing arrangement (13 - 19, 30, 50, 51) detects the running of the engine from a signal (Ub) arising at a generator (11) driven by the engine (10) or at a load (12) connected to said generator (11). The signal (Ub) contains components of longer (Tm) and shorter (Tmn) duration which are assessed both separately and together in an evaluation unit (15). The short-duration (Tmn) signal component can be derived from commutation oscillations (40) occurring in the signal Ub if the generator (11) is designed as an a.c./three-phase generator with rectifiers and phase junction.
