Patent DE-3935809-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: B61L3/22
Filed: 1989-10-27
Abstract: For cab signalling and also for automatic vehicle control, signal positions and temporary travel restrictions must be transmitted to the vehicles reliably in terms of signalling technology. For this purpose, a device is disclosed which has a line conductor loop (LL) which is laid on the track section, for example in the track at the signalling location, and a track section device (SG) which feeds said loop and contains for all the possible signal positions in each case two data sets which are identical with one another stored in various memories (SP1, ..., SP4). The current signal position is tapped off at the signal (S) and transferred in coded form to the track section device or it is transmitted from a central track control unit via a data connection to the track section device. The latter transmits the two associated data sets together alternately and continuously onto the line conductor loop with a memory code in each case. The on-board control units of the vehicles which are inductively coupled to the line conductor loop compare the data sets which are equipped with different memory codes and only process further the data contained therein if the data sets are identical with one another with the exception of the memory code. <IMAGE>

Filed: 1989-11-06
Abstract: A circuit is disclosed for providing a digital trigger generator for oscilloscopes and similar triggered instruments such as logic analyzers. The digital trigger circuit includes an analog-to-digital converter 104 and a digital comparator 106 to compare two digital values to determine triggering conditions. The desired triggering level is set in a digital register 108, connected to an input of the comparator, by use of a microprocessor 110. The microprocessor is programmed to instruct the trigger signal generator as to which two of the three output signal states (A>B,A=B,A<B) signalled by the comparator are to be used to initiate the triggering signal. The use of two digital comparators (206, 207) and two registers (208, 209) Figure 2 allows for the trigger level and the noise sensitivity to be independently set digitally. <IMAGE>

IPC: H03L7/197
Filed: 1990-03-01
Abstract: In a frequency synthesiser including a controlled oscillator 10, variable divider 20 and a phase comparator 26 arranged in a phase locked loop, frequency modulation is achieved by applying the modulation signal at 61 directly to the oscillator 10 and a phase signal Pm corresponding to the frequency modulation signal is added at 38 with the phase comparator 26 output to cancel variations in the comparator 26 output due to the applied modulation signal and arising in the case of the frequency modulation lying within the loop bandwidth. A calibration circuit 114 under the control of a microprocessor 110 and a coherent detector 94 permits initial adjustment. Fractional division ratios may be obtained by varying the division ratio of 20 in a periodic manner under the control of accumulators 44, 52 and a delay circuit 56. Phase jitter due to this variation is eliminated by supplying a corresponding error signal to adder 59 or by phase shifting one of the two inputs to comparator 26.   <IMAGE>

IPC: F23D14/64
Filed: 1990-05-19
Abstract: The invention relates to a method for the combustion of fuel gas with free oxygen-containing gas, in particular with low-pressure fuel gas supply (< 100 mbar) and using the Coanda effect. i.e. that low- pressure fuel gas is supplied to a suction/mixing pipe over the entire cross-section except for an annular gap adjacent to the wall of the suction/mixing pipe, while at the same time free oxygen-containing gas at higher pressure is fed in via the annular gap and thus an additional suction of fuel gas arises. In order to improve such a low-pressure combustion method, to design it efficiently, reliably and easily regulably, it is proposed that only a primary part of the free oxygen-containing gas necessary for the combustion is supplied via the Coanda annular gap (5[216C]) inside the suction/mixing pipe (2), while a secondary part is only supplied to the gas mixture leaving the suction/mixing pipe, the values for     - pressure and quantity of the primary free oxygen-containing gas - pressure and quantity of the secondary free oxygen-containing gas   being adjusted as a function of the available fuel gas pressure, the desired adjustment of the combustion and the combustion efficiency and the purpose of application and characteristic data relating to safety regulations.

Title: Closing crude oil blowouts - using ground based remotely controlled clamps, and trolley running on rails to carry tooling as requested
Inventor: TIEMER PEER
IPC: E21B35/00
Filed: 1991-04-30
Abstract: A means of shutting off flow in crude oil or natural gas well heads, which have blown out. The invention claims to bring under control blow outs, giving greater protection to machinery and personnel. The novelty is due to the use of remotely controlled equipment running on rails. Rails with a U section between 10 and 30 m are laid onto large supporting plates, with turned up edges, resting on the ground. The foremost plate has a V cut out to centralise it around the feed pipe. Flexible couplings of the rails to the support plates allow for the unevenness of the ground. A second guide fastened to the foremost rail ensures that the pipe is vertical to the rails, and hydraulic jacks ensure that the rails return to the horizontal. A hydraulic fork attached to the rails, grips the projecting pipe and clamps the pipe shut.

IPC: G05B23/02
Filed: 1991-07-09
Abstract: In order to detect defects in a sensor 10 which produces an output signal 13 forming the actual value feedback signal 13 for a controller 14 and which is preferably a differential inductive displacement sensor, a comparison is made in unit 16 of the actual value 13 with the output of the controller 14, a fault being detected if the actual value of the sensor lies within a predetermined range (around the normal mid-range value) and the controller is at the same time at one of its stops during a predeterminably longer time. As shown the sensor comprises inductors L1, L2 and a movable element 11. The inductors are fed with phase- opposed square waves +U, -U and their mid-point is connected to evaluation circuit 12. The output 13 of the circuit 12 is thus dependent on the position of the element 11 and forms the feedback signal for the controller 14 coupled to the element 11 via drive 15. Comparison logic 16 receives the actual value 13 and the controller output signal. A fault signal is produced by the logic circuit as described above, and also if the value 13 lies outside an allowed range. <IMAGE>
