Patent DE-4324956-A1 (DE)
Title: Drilling grab
Inventor: HARTFUSS WOLFGANG DIPL ING
IPC: E21B27/00
Filed: 1993-07-24
Abstract: The invention relates to a drilling grab with at least two grab shells which are each linked via a connecting element to a tension element, which can be acted upon by the rope tackle line of a winch rope, for closing the grab shells, at least one spring unit being provided which counteracts the force of the rope tackle line. The invention consists in the fact that the tension element is a guide element which, via force-transmission elements acted upon by the force of the spring unit, runs on guide rails which, in the direction of the lifting movement for closing the drilling grab, have one or more different inclines in accordance with the action of the spring force required. The essential advantages of the invention consist in the fact that, in the drilling grab, the locking force to prevent unintentional, automatic closing can be arranged to be considerably greater and the action of force during the closing operation can be arranged to be considerably smaller.

Patent DE-4328862-A1 (DE)
Inventor: WILLMANN GERT DIPL ING
IPC: H04L12/70
Filed: 1993-08-27
Abstract: During overload conditions, the probability of loss of data packets (D4-D8) is approximately of equal magnitude in all queues (QU1, QU2). The loss probability cannot be graded. Data packets (D4-D8) are temporarily stored in a number of logical queues (QU1, QU2) which are dynamically allocated the storage locations of a common buffer memory (MEM). The unavoidable loss of data packets is systematised by selective discarding of data packets. A data packet (D6-D8) stored in a low-priority queue (QU2) is deleted when an incoming data packet (D1) is allocated to a higher-priority queue (QU1) and the total length of queues has exceeded a certain length.   - A buffer with various adjustable access control or operating procedures can be implemented in a simple manner.   - Fast solution, suitable for ATM.   <IMAGE>

Title: Water desalination assembly fluid tank
Inventor: BERNHARD JUERGEN
IPC: C02F1/14
Filed: 1993-12-03
Abstract: In a water desalination process a medium is heated in solar energy collectors, after which part of the solar energy so gained is recovered from condensation as latent heat and then surrendered to the salt water. The novelty is that: - the salt water is delivered to a storage vessel above the evaporator and condenser, from which it flows under gravity first through the condenser and then through the solar collector and to the evaporator. - the heated liquid medium e.g. salt water flows from the top into the evaporator which incorporates a non-woven fleece mattress - an exchange of circulating air takes place between the evaporator chamber and the condenser chamber by means of natural convection - the air bearing an enriched load of evaporated moisture, condenses in the condenser outer walls which incorporate a number of channels, through which flows the salt water - some of the latent heat of condensation is then surrendered to the salt water - the condensed water flows down the channel outer walls and is returned to a storage tank. Further that the assembly is fabricated from polypropylene.
