Patent DE-2326307-A1 (DE)
Title: Inwards curved surface roughening - by grinding powder made to slide over surface
Inventor: ROEHRICH HEINZ
IPC: B24B31/00
Filed: 1973-05-23
Abstract: The roughening for keying material surface layers is effected by filling the bowl like components with a grinding material, tilting to uniformly distribute the material and the imparting motions causing the material to slide over the surface. Pref. 70 um Al2O3 powder with 10 mm Al2O3 balls are employed for grinding of the surfaces which are rocked by being held against a socket attached to the end of a vertical shaft. The method is used for the surface of X-ray image amplifier blanks prior to the application of luminescent surface coating. It yields very evenly prepd. surfaces.

Title: Four-terminal network with high value terminal resistor - compensates output capacitance of wideband amplifying stage and load input capacitance
Inventor: KANBERG HORST DIPL-ING
IPC: H03K5/02
Filed: 1973-08-10
Abstract: The network is bilaterally insertable and also compensates about the same input capacitance of a following load. A bridged T circuit is provided on both sides of the network, whose series arm consists of two coil halves coupled together and connected in series. The T-circuit shunt arm consists of one of the capacitances to be balanced, and the bridging component is a capacitor. The series arm inductance is about equal to the product of the square of a terminating impedance and the capacitance to be balanced. The two bridged T circuits are connected in series by series-connecting the two coils and their parallel capacitances. The terminating impedance is connected as a shunt arm to the junction point between the two coils.

Title: Electrolytic generation of hydrogen and oxygen - using reversing polarity to prevent polarisation
Inventor: HARTKORN KARL HEINZ
IPC: C02F1/72
Filed: 1974-04-08
Abstract: Hydrogen and oxygen are produced by the passage of an electrical current through electrodes immersed in an electrolyte and through electrodes located in the gas space above the electrolyte under low press. giving a corona discharge. A direct current is applied to the electrolyte but with a superimposed and variable directional change to prevent polarisation. The electrodes in the gas spaces are fed with a high frequency voltage in excess of 300 V. Useful (1) as a means of storing energy, whereby power stations running at a constant output generate H2 and O2 at night, which stored and used as fuel for peak-shaving during the day; (2) in electrolytic waste water treatment processes. Up to ten times as much H2 and O2 can be generated as in conventional cells using the same power consumption.

Abstract: The attenuating circuit, for HF signals, has a circulator (Zi1) coupled between an input matching circuit (V1) and an output matching circuit (V3). In the frequency band of interest all the input signal passes through to the output port. A variable matching circuit (V2) connects the circulator's third port to an absorber (A). The absorber attenuates signals outside the band of interest. All the matching circuits adapt the circulator's impedances to those of the lines at the required frequencies. A second circulator (Zil) may be coupled via a fourth matching circuit to the absorber's input and to the input and output lines.

Title: Transposition independent frequency spectrum - for harmonics of speech fundamental frequencies in devices for sub-band transposition
Inventor: BUCHMANN KURT DR PHIL
IPC: H04K1/04
Filed: 1974-05-31
Abstract: Speech signal band is divided in sub-bands of equal width at the sender and are transposed and possibly inverted, then they are restored to their normal positions in the receiver. The frequencies at the speech band lower end, and half the sub-band width are in a ratio of two whole numbers. This ratio is also a whole number. This numerical arrangement simplifies, the collection of information from the system. By obtaining a carrier frequency by combining the lower frequencies and the sub band in this ratio, inversion information is eliminated from the sub bands.

Title: Damping circuit for stepping motor - has signal generators used for deforming edges of motor drive pulses into stepped slopes to reduce oscillations
Inventor: ANDREW FRANKLIN
IPC: H02P8/32
Filed: 1974-06-24
Abstract: The damping circuit, for a stepping motor, has signal generators (11,12) whose output signals are superimposed on the stepping pulses that drive the motor such that these pulses are effectively shifted in phase. The output signals of the generators deform the edges of the stepping pulses into stepped slopes that suppress the tendency of the motor to oscillate. The advantage of the damping circuit lies in its obviating cumbersome mechanical damping systems and thereby opening up new areas of application for stepping motors. The step voltage generators are coupled to the output stage via differential amplifiers.

Title: Complementary MIS ccts. - impurity atoms in transistors with channels of same type as control layer ensure charge compensation
Inventor: SCHLOETTERER HEINRICH DR
IPC: H01L21/86
Filed: 1974-09-30
Abstract: The p- and n-channel field effect transistors are of the enrichment type base on a semiconductor layer coated over an insulator and provided with conducting zones to form the drain and source and also featuring the gate layer with its electrode. The conducting zone near the boundary layer facing the insulator is of the opposite type to that of the transistor channel, and the main characteristic of the process is the epitaxial growth of the semiconductor on the insulator, thus decreasing the failure rate when compared to the conventional methods of manufacture. The implantation dose is not critical, the only criterion being the avoidance of overcompensation of the boundary charge.

Title: Tension control for unrolling paper sheet - using electrically driven variable delivery hydraulic pump as energy absorber or source
Inventor: MAEKELAE AARNE OLAVI DIPL ING
IPC: B65H23/182
Filed: 1974-10-01
Abstract: A roller measures the tension by strain gauges associated with its end bearings whose separate signals are transmitted through amplifiers to an integrator which transmits a signal into the controller. The instrument also feeds in a signal representing the desired tension. An output signal represents the difference and this is used to affect the delivery control mechanism of the hydraulic pump driven by an electric motor. A hydraulic pump is mechanically driven by the stock roll and the two pumps are in series. If now the roll needs braking, the variable pump will be set to deliver less. The pump will now be attempting to drive it as a motor, will increase its speed and so the speed of the electric motor which will temporarily act as a generator brake.
