Patent DE-4027735-A1 (DE)
Inventor: SCHREIBER HANS DR DR
IPC: G07F7/08
Filed: 1990-09-01
Abstract: The invention relates to a process and device for secure remote data transmission, preferably for cashless payment transactions, in which an information substrate is provided via a read/write unit with recallable information in addition to fixed storage recognition authorising the user so that the information substrate is suitable for data transmission or payment transactions and is protected against misuse by bearing an individual code and in that the information substrate responds via remote data transmission systems to at least one other information substrate or at least one read/write unit or can be contacted and read out by a read/write unit via its interface, whereby for money transfer an additional code secures the process and the bank-to-bank booking process and in all makes bank errors virtually impossible in money transfers, while in pure on-line operation fully preventing fraudulent operations by "uncovered" information substrates, nowadays the equivalent of uncovered cheques. Furthermore, timers of preferably portable read/write units make possible the limited-time storage of programmed PINs for the authorisation of received information substrates.

Title: Lightweight gripper for robot -  has gripper fingers linked to centrall air cylinder by scissors linkages
Inventor: SAADAT MOHSEN M DR ING
IPC: B25J15/10
Filed: 1990-09-19
Abstract: The gripper has a rear plate (14) which is secured to the robot arm and a front plate (12) which can be moved to and fro relative to the rear plate by a central pneumatic cylinder unit (7). Gripper fingers (2), spaced for example at 120 deg., are connected to the rear and front plates by scissors linkages (27). The end brackets (30) of the scissors linkages are secured to inclined surfaces (16) of the rear and front plates, thus minimising shear forces across the joints and facilitating lightweight construction. The geometry of the scissors linkages ensures that as the jaws (19) are closed by operation of the cylinder unit no axial movement occurs. USE/ADVANTAGE - Lightweight construction permits high speed response with less wear on robot.

Title: Preventing penetration of harmful substances into ground water - by depositing horizontal layers of hygroscopic granulate into earth above water level
Inventor: FABRITZ GERHARD
IPC: C02F1/28
Filed: 1991-03-05
Abstract: Penetation of harmful substances into ground water zones is hindered or opt. avoided by depositing one or more horizontal layers of a very hygroscopic granulate into the earth zones lying above the ground water and contg., e.g, heavy metals, nitrates or oils, by means of air canon. The substance retards the rate of flow of water, mainly rain water and melted snow, into the earth, and each layer absorbs part of the harmful substances. Pref. granulate is of a copolymer. When several layers are introduced, the first is at a depth of about 30cm, and the amts. of granulate in the different layers may be the same or different. In an example, a ram (1) was rammed into the earth (2), and a coplymer granulate (4) was introduced into the earth through a pipe (3) and a nozzle (5), under a pressure of 10 bars, to form a layer (a) at a depth of 30cm. Further granulate (4',4'') was deposited in layers (b,c). The water table was at (6).

Title: Field strength dependent signal evaluating method for car radio - comparing obtained field strength profile with stored field strength profile held in memory to read out associated information
Inventor: BERNINGER HARALD DIPL ING
IPC: H04H20/57
Filed: 1991-11-11

Title: Clamping system for tools with hollow locating spigots - uses initial movement of drawbar to open claws so that clamping surfaces of tool and claws come into full contact before clamping force is exerted
Inventor: BRANGS ECKHARD DR ING
IPC: B23B31/26
Filed: 1991-11-27

Inventor: ROSCH RAINER DR
IPC: H05B39/08
Filed: 1992-09-17
Abstract: In the case of a process for electronically dimming loads, especially lighting devices, the switched-on duration per cycle of the AC voltage supplying the load (BL) is varied in accordance with a specification by means of a control element (PO;TA) via a variable current conducting period, with the aid of a switching element (SG) which is located in the load circuit and is controlled by a control circuit (SS) in accordance with the phase-gating principle or phase-chopping principle. Interference effects occurring in this case are intended to be eliminated. According to the invention, during the determination of the current conducting period, as well as taking into account the value which is predetermined by the control element (PO;TA), the control circuit (SS) also takes into account further automatically determined values, in such a manner that, at least during a transition period, it defines current conducting periods which deliberately deviate from the specification by the control element (PO;TA). <IMAGE>
