Title: Known digital word bits finding device - bits inserted at equal spacings individually and periodically between other bits
Inventor: HAERLE HANS GEORG DIPL ING
IPC: H04J3/14
Filed: 1974-02-13
Abstract: A backward counting binary counter can carry out a number of counting steps equal to that of bits in the equal bit spacings. A clock pulse generator has two outputs with the second output connected to the counter clock pulse input. Clock pulse phases at the generator outputs differ by 90 deg. AND gate inputs are connected to the outputs of the counter stages, and its output delivers a signal at the counter initial position. A second AND gate first input is connected to a first signal input, its second input to the clock pulse generator output; its third input to a terminal for counter resetting interruption, and the fourth input to the first AND gate output.

Title: Gas permeability control for sinter agglomerates - uses hot gas dosing to optimise mixture grading and travelling grate speed
Inventor: KILIAN ALOIS DIPL ING
IPC: C22B1/20
Filed: 1974-03-09
Abstract: The hot gas quantity supplied to the travelling grate is measured to be directly proportional to the grading characteristic of the mixture and the signal received is used for the gradual variation of the other parameters influencing the permeability. For measuring the gas permeability the pressure within the combustion chamber the variation of the air quantity by varying the fuel/air ratio can be achieved. Alternatively the control can be achieved by varying the fuel quantity at constant air quantity. The same aim can be achieved to monitor and control one or several of the following parameters; height of agglomerate layer, coke and return products quantity of the agglomerate, humidity and ignition intensity.
Patent DE-2416831-A1 (DE)
Title: Industrial electrical connector - has narrow elastic slot in insulating sleeving around socket to grip clamping screws
IPC: H01R4/36
Filed: 1974-04-06
Abstract: The industrial connector has a slot in the insulating sleeving that encloses the socket. The slot is elastic and accepts the clamping screws. The slot's width is less than the diameter of the screw's shaft and therefore clamps the screw. The slot runs longitudinally with respect to the socket and is closed by a web at the end facing the cover plate. The insulating sleeving is thickened in the region of the slot. The advantages of the connector lie in the simple manner in which it can be mass produced and in the slot's ability to clamp the screw.

Title: Dual brake controls for railway engine - with safety venting controls operated by master key in cab being used
Inventor: FALKE ERICH
IPC: B60T15/16
Filed: 1974-08-09
Abstract: The train brakes are controlled from either cab of the engine by identical switches. Each switch is in line with a control switch operated by the safety key. This is inserted by the driver into the driving position and turned. The key operates a slider control to open that brake control to the supply line. In the non-operative position the control is vented. The slider control operates a change over valve which coupled the respective control to the relay pneumatic brake valve which controls the train brakes. Even if the change over valve operates inadvertently through pressure changes, then the key operated slider still isolates the respective control with the removed.

Title: Speed fluctuation measuring circuit for TV disc recorders - measures buckle eccentricity and ellipticity using adder and two subtractors
Inventor: JAHNEL BENNO DIPL PHYS
IPC: G01B11/02
Filed: 1974-11-14
Abstract: The speed-fluctuation measuring circuit, for television disc recorders, also measures the buckle, ellipticity and eccentricity of the recording disc and has an adder (12) and a subtractor (13). A setting signal (Us) derived from the frequency of the line sync. pulses (Z) is applied directly to and delayed by a half-image (20ms) to the inputs of the adder and subtractor. The outputs of the adder and subtractor are proportional to the parameters being measured. Eccentricity is measured at the subtractors output, and ellipticity at the adder output. The disc buckling is measured by subtracting (16) the outputs of the adder and subtractor.

Filed: 1975-04-15
Abstract: Pyrolysis of H2O comprises reacting H2O with I2 and SO2 to form HI and H2SO4, followed by pyrolysis of the HI to H2 and I2 and of the H2SO4 to O2 and SO2. The H2O pref. is used in excess w.r.t. I2 and SO2, esp. in a 2-molar excess w.r.t. the I2. The pyrolysis temp. pref. is 500-700 degrees C for the HI and 600-1000 degrees C for the H2SO4. Alternatively, the reaction of H2O with I2 and SO2 can take place in the presence of a metal cpd. forming a sulphate, which is pyrolysed at a temp. up to 1000 degrees C to O2, SO2 and the metal cpd. Suitable metal cpds. are (hydr)oxides and (bi)sulphites of gp. III-VIII metals, esp. Ti, Zr, Al, Zn, Fe, Co, Ni, Cr, and V. Pyrolysis is pref. carried out in a closed system, the regenerated I2, SO2 and opt metal cpd. being recycled. The H2 may be used as a fuel. The process operates in a closed system and utilises the reagents economically, without marked heat loss. The H2 produced is free from harmful impurities.

Title: Video disc stabilisation system which removes distortion - has disc held in contact with supporting table by external force to assure flatness
Inventor: SOEDING HORST DIPL PHYS
IPC: G11B17/32
Filed: 1975-05-07
Abstract: A table for the support of gramophone discs, especially thin non-rigid discs for video recordings, which ensures that the record remains flat against the supporting table and removes distortion due to unevenness of the disc itself, which may be particularly disturbing in optical scanning for reproduction. External force is applied to keep the disc in contact with the table. This may be effected by forming the table as a very funnel, so that the disc is forced in contact with it by centrifugal force as it revolves, or the materials of the table surface and the disc may be so chosen that the suffer a mutual electrostatic attraction. A further alternative is to use induced currents to provide attraction to a metallic surface.
Patent DE-2527635-A1 (DE)
Title: Secondary pressure circuit for hydraulic power systems - uses pressure compensated flow valve and pressure reducing valve local to clamping cylinders
Inventor: MURATA HIKARU
IPC: G05D16/16
Filed: 1975-06-20
Abstract: A pressure reducing circuit for hydraulic power systems enables the applied force generated by an actuator to be maintained at a constant value independent of the main supply. The area of application relates to situations where the actuator pressure is less than that of the mains supply. The output of a power pack provides a primary pressure for a directional valve over two lines as well as supplying any other system component lines. When the forward stroke of a cylinder is used to apply a clamping force to an object that calls for a lower pressure than the supply, a secondary pressure level is generated. The main valve output if coupled over a flow regulator to a pressure reducing valve. This latter valve unloads when clamping is effected.
