Patent DE-3805328-A1 (DE)
Title: Method for transmitting measurement values in a transmission of the measurement values by optical fibre
Inventor: KOENIGSDORFER WALTER
IPC: G01D3/02
Filed: 1988-02-20
Abstract: To detect more accurately the measurement value or actual value of electrical measurement value signals (UM) which are transmitted by means of a signal transmitter (29) having a transmitting diode (8) via an optical fibre (9) to a signal receiver (19) which exhibits a photodiode (20) at the receiving end, a calibration device (10) which generates at least two different calibration signals of predeterminable calibration time (T1-T3) is provided at the transmitter end. During the calibration cycle, the signal transmitter is unilaterally isolated from a sensing resistor (RM) by means of a change-over switch (2). A series circuit of resistors (R14-R17), some of which can be bypassed by switches (11, 12), can be used for applying different potentials to an input of the signal transmitter (29). These potentials are evaluated in a computer or microprocessor (24) connected to the signal receiver (19) and used for calibrating subsequent useful or measurement signals. A zero level which is evaluated at the receiving end for setting a zero point is preferably transmitted within a calibration cycle. Additional minimum and maximum value levels can be used for calculating measuring range factors for the negative and positive part of a transmitting-diode 1/current characteristic. A calibration cycle can take place after the switch-on of the signal receiver (29) and thereafter in dependence on the process (28) and/or cyclically (T4). A return line from the signal receiver (19) to the signal transmitter (29) is not required. <IMAGE>

Patent DE-3811071-A1 (DE)
Title: Solenoid injection valve for internal combustion engines
Inventor: SCHAUER WALTER
IPC: H01F7/16
Filed: 1988-03-31
Abstract: Injection valves of the said type are known, but despite scavenging with excess fuel exhibit injection failures in extreme engine operating conditions. By contrast, the injection valve according to the invention has the following measures that the bobbin enclosing the round rod has a receiver opening for the round rod, which opening is approximately equal to twice the diameter of the round rod in the area of the stop surface for the valve closing body. The injection valve according to the invention prevents failures of the fuel injection in extreme engine operating conditions, any loss of magnetic force occurring due to the new characteristic features being partially compensated for by easier adjustment of the moving parts, caused by compensating volumes.

IPC: H04H20/76
Filed: 1989-01-21
Abstract: In a method for the remote controlled substitution, in particular of a defined advertising spot by a test advertising spot for selected receivers, it has been provided that bi-phase modulated start codes are transmitted in the picture lines outside of the TV picture visible on the video screen for the control of the address-distributed TV signals for the program part to be substituted.

Abstract: In a gaming machine with win output, one of a plurality of visible symbol representations can be triggered according to a random function by means of a game-initiating unit (5) actuable as a function of the insertion of money or the like. Predetermined symbol representations, namely the win-symbol representations, are each assigned a predetermined win. When a win-symbol representation detector (11) detects a win-symbol representation, a digital win representation assigned to it by a win allocator (15) and, as a function of this, the output of the win assigned to it can be triggered in a win output unit (19). To persuade a player to play more often, the gaming machine contains a device (17, 20-39) which selectably blocks the win output and which increases the win possibility with an increasing number of wins stored intermediately during a blockage of the win output. <IMAGE>

Patent DE-4012677-A1 (DE)
Inventor: NAGASAWA MASAHIRO
IPC: H04N11/20
Filed: 1990-04-20
Abstract: To convert an NTSC video signal a into one b with a PAL type sub-carrier, the output r1 of a clock 44 at four times the PAL sub-carrier frequency fsc is passed to a divide by four frequency divider 45 and logic 46 - 48 to provide three signals A1 - C1 each at fsc and with relative phases of -45 DEG , 0 DEG , and +45 DEG . The latter or a zero signal D1 are selected at SW1 for mixing at 42 with the NTSC sub-carrier r2, according to PAL phase (B1 or D1) in the active line period, or colour burst phase (A1 or C1), and the resulting signal c is mixed at 4 with the separated chrominance component of the NTSC signal a. In a modification (Fig 13) both sum and difference signals from the mixer 42 are used. The arrangement is such that only colour signals on alternate lines are converted, when signal B1 is provided, and the missing lines are produced from the converted lines. A variable gain circuit 50 enables the reduced chrominance resulting from such a process to be corrected automatically; the burst amplitude is reduced so that a subsequent variable gain circuit in an ACC detector (22, Fig 3) increases the level of the whole signal to that of a normal (unconverted) signal. <IMAGE>
