Title: Apparatus for filling sacks having one open side
Inventor: HUEWELMANN HELMUT
IPC: B65B7/08
Filed: 1993-03-22
Abstract: APPARATUS FOR FILLING SACKS HAVING ONE OPEN SIDE                 ABSTRACT           Sacks  which  are  open  on  one  side  and  are preferably provided with side folds are gripped at their side sections in the area of their open edges by pairs of grippers, which can be displaced towards and away from each other.   The lateral walls of the sacks are pulled apart adjacent the open edges between the grippers by suction elements arranged in a rack of the apparatus.  In the rack there are arranged filling necks which can be lowered and raised into and out of the open sacks.  A sealing device closes the open edges of the sacks which are closed by moving apart the grippers thus pulling the edges tightly against each other.   In order to be able to detect the desired net weight of the filling quantity with a high accuracy, the pair of grippers and the drive means for the opening and closing movements, and for the displacement of the grippers towards and away from each other, are arranged on carrying means which are connected with the rack by means of weighing devices.  This separate carrying means minimizes the amount of the apparatus which must be included in the gross weighing thereby minimizing the relative error.

Title: Optical communications system employing fiber-optic amplifiers and control of the transmitter wavelength
Inventor: HEIDEMANN ROLF
IPC: H04B10/50
Filed: 1993-03-17
Abstract: Fiber-optic amplifiers as they are employed in optical communications systems, for example those including light waveguides doped with Er3+,  have a gain that is highly dependent on the wavelength in the wavelength range of interest.   According to the invention,  the emission wavelength .lambda.o of the semiconductor laser of  an  optical transmission system is regulated by way of a control device provided within the optical transmitter to that wavelength at which the fiber-optic amplifiers have a maximum gain. The control device finds the optimum wavelength in that it evaluates  the  light  absorption  of  a  reference  light waveguide piece whose maximum lies at the same wavelength at which the fiber-optic amplifier has its maximum gain and regulates the emission wavelength of the laser to the wavelength of the maximum absorption in the reference light waveguide piece.

Abstract: Hitch structure for connecting first and second implements for operation side-by-side in the field, and one directly behind the other for transport.  A freely rockable swing hitch has a forward end connected to one side of the first implement frame for pivoting less than 180° about an upright axis located inwardly from the side.  A latch on the swing hitch mates with a frame-mounted rear bracket to secure the hitch in the transport position.  The same latch secures the swing hitch to a bracket on the forward towing hitch when the swing hitch and towing hitch are in the field-working position.  A sliding tubular member and two-position latch selectively secure the towing hitch in either a central transport position or an offset field-working position.  Both latches have release levers for changing from one position to the other, and the latches automatically lock in the new position when the desired positon is attained.  A steering mechanism located on the caster wheel assembly of the trailing implement and operable from the tractor cab guides the second implement as the swing hitch pivots during conversions.

Title: Optical communication system with a power limiter for high-energy pulses
Inventor: CHESNOY JOSE
IPC: H04B10/07
Filed: 1993-04-08
Abstract: Abstract Optical Communication System with a Power Limiter for High-Energy Pulses In optical communication systems with optical with optical amplifiers, there is the danger of system components being damaged in the event of a break in the fiber-optic link, e.g., due to fiber breakage.             This can be explained by the emission of high-energy pulses.             To prevent such pulses from propagating in the fiber-optic link, a power limiter which, by introducing attenuation, limits the optical power of the pulses to a value not dangerous to the system components is inserted in the fiber-optic link.  The attentuation is provided by two-photon absorption.             (Fig.1)
