Title: Back tensioner for occupants of ejector seat - prevents injuries to spinal column by stretching back during seat operation
Inventor: BECK ARMIN DR
IPC: B64D25/02
Filed: 1973-08-02
Abstract: Experience has shown that the incidence of infractures to the spinal column of personnel ejected from aircraft wal lower when the occupant of the seat was in a stretched position. The stretched position was mainly obtained by bending backward. The seat described is therefore provided with a back-rest which when the ejector seat is operated is expanded either mechanically or by air pressure. The extension is local in the centre region of the back of the occupant. An elastic hollow body is incorporated in the back rest of the seat for this purpose.

In order to achieve the required insulation properties in each laminated sheet are included one or more intermediate sheets of net shaped material which in completed lamination are forming enclosed cells filled with air of equal or lower pressure than air pressure out side the lamination. The net layers are produced from adhesive material and in order to prevent formation of temperature bridge they are of different thickness and their cells are of different size and shape. The top or bottom layer of the lamination is from material penetrated by light or reflecting light.
Patent DE-2350466-A1 (DE)
Title: Metallising of ceramics which conduct oxygen ions - thorium oxide-yttrium oxide ceramic coated with tungsten, molybdenum or niobium
Inventor: ZIEGLER GEB HAAG RENATE
IPC: C04B41/51
Filed: 1973-10-08
Abstract: Metallising process comprises applying a powder contg. tungsten-, molybdenum-, or niobium- oxide to the surface of the ceramic followed by sintering in a reducing at atmos. in which the powder penetrates the ceramic and is simultaneously reduced to the metal on the surface. The substrate is pref. annealed in a reducing atmos. prior to the metallising treatment in which a powder with a particle size below 1 mu is used. The ceramic e.g. ThO2-Y2O3, is used as a solid electrolyte in appts. for determn. of the oxygen content of gases and liq. metals. Metallising facilitates soldering of the ceramic to metal parts of the appts. to form joints which can withstand the thermal stress arising when the appts. is used at 300-800 degrees C. Process allows a much lower temp. to be used during sintering, thus preventing the tungsten from attacking the ThO2 in a ThO2-Y2O3 ceramic.

Title: Photo-electric pulse pick-up - photo-element has signal evaluator to detect blood pulsations from modulation of received light
Inventor: KORN VOLKER DIPL ING
IPC: A61B5/024
Filed: 1973-12-28
Abstract: The irradiating light source emits light pulsewise in the cycle of a generator that also controls a changeover switch which connects the photoelement to the evaluator solely for the duration of reception time of the light from the source. The changeover switch connects the photoelement, during intervals between light emission, to a second signal evaluator which includes at least a first threshold discriminator to release an electrical alarm signal when the input signal voltage at the input of the second signal evaluator exceeds a preset threshold value. Interference by stray scattered light is detected and results in an alarm signal.

Title: Adjustable drive unit - has motor pivoting on two axes with rounded friction wheel bearing against bevel wheel
Inventor: GLUNZ WERNER
IPC: B65H54/74
Filed: 1974-09-24
Abstract: The unit is particularly for winding machines. The driving motor (9) pivots about two axes in the shape of supporting bolts (4, 11), so that to adjust the speed the rounded friction wheel (7) with its motor rolls over the bevel friction wheel (3) in the axial direction. The wheels face in opposite directions, so the larger diameter part of the rounded wheel is in contact with the smaller diameter part of the bevel wheel and vice-versa, dependent on the setting. Alternatively, the rounded wheel can be mounted on the output shaft and the bevel wheel on the motor shaft, and the spring (12) can both counterbalance motor weight and provide the necessary pressure between the wheels.
