Patent DE-2346277-A1 (DE)
Title: Semiconductor laser pulse modulation - uses threshold exceeding current during pulsing periods
Inventor: RUSSER PETER DIPL ING DR
IPC: H01S5/062
Filed: 1973-09-14
Abstract: Pulse modulation process for semiconductor laser, in which the laser is so energised by the modulation pulses that the current flowing through the laser in the period between two pulses is substantially below the current threshold value. During the laser pulsing the current flowing through the laser has a value well above the threshold current. A storage diode is in parallel to the semiconductor laser and is charged during the intervals between the modulation pulses when the subsequent modulation pulse is expected to energised the semiconductor laser. The storage diode cathode is connected on one side to a laser diode cathode and on the other side to the negative pole of an operating voltage source, via an inductance and a transistor.

Title: High pressure crystal pulling furnace - with symmetrical arrangement of support, pulling chamber and seed crystal holder
Inventor: GEHRING JOHANN
IPC: C30B15/30
Filed: 1973-10-03
Abstract: In a crystal pulling furnace, the support is arranged in a vertical line with the high-pressure pulling chamber and the crystal holder, symmetrically to the pulling axis. The crystal holder forms, together with the high-pressure pulling chamber cover which is designed as a dome, a subassembly which is mounted on the support movably in the direction of the pulling axis.

Title: Continuous measurement of fuel consumption - is related to distance travelled with measurement of speed and consumption
Inventor: BERNER GIANNI DR
IPC: G01F9/02
Filed: 1974-04-04
Abstract: A data pick-up records the instantaneous speed of the vehicle and another data pick-up records the instantaneous fuel consumption.

Title: Counterflow heat exchanger for nuclear power plant - is divided into sections with secondary fluid traversing them successively
Inventor: ECKER HANS
IPC: F28F9/22
Filed: 1974-04-05
Abstract: The heat exchanger has an outer cylindrical casing which has internal cylindrical partitions along its entire length and also radial partitions so as to divide the entire space into a number of segmental longitudinal compartments. Each of these compartments contains a tube bundle carrying the fluid being heated and the primary fluid flows round all the tube bundles through all the compartments longitudinally. The tube bundles are connected to each other so that the fluid being heated flows through them all in series. A similar design can be constructed with a polygonal rather than circular cross section. The construction reduces the length required for a given cross section for a given heat transfer.

Title: Tensile testing superplastic materials - using computer to calculate stress/strain proportionality factor at various tearing speeds
Inventor: VOLL HUBERT PAUL
IPC: G01N3/08
Filed: 1974-05-20
Abstract: The deformation properties of superplastic matls. are determined in a tensile test rig by determining the deformation rate at various tearing speeds of the speciment. The logarithms of the stresses are then placed as a function of the logarithms of the strains, and the constant K which is the proportionality factor between stress and strain is found from the intersection of the straight line with the ordinate (stress axis). This system can be used for ferrous as well as for non-ferrous metals. Its results indicate the optimum deformation rate for a superplastic matl.

Title: Semiconductor capacitative microphone element - using poly-crystalline base material has flexible capacitor electrode
Inventor: KUSANO MASAAKI
IPC: H01L21/762
Filed: 1974-07-15
Abstract: The microphone element consists of two audio sensitive parts mounted on a single base of poly-crystalline material. The junction between the two parts, and the base of the crystalline material form the two electrical external contacts. Pressure waves hitting the surface of the device cause a noticeable difference in the electrostatic capacitance between the plates, and this property is used to convert the audio signal, into an electrical signal. Electrodes for electrical connections are mounted on the flexible diaphragm disc.

Title: Longitudinal bearer for motor vehicle chassis - has impact energy absorbing cross section producing corrugations starting at slits
Inventor: TORKE GERNOT DIPL PHYS
IPC: F16F7/12
Filed: 1974-12-05
Abstract: The bearer possesses a 'U' shaped cross section with outward facing flanges (2, 3) which are spot welded to a flat base (4) to form a box bearer. All four cross section corners on a common place are then provided with an incision with a width of 1mm. Alternatively the flanges only may be provided with a similar incision (W). In the event of a longitudinal overload, the bearer will develop corrugations in the region of the incisions to absorb the impact energy. This is due to buckling of the highly stressed region having the slits at the cornerS.
