Patent DE-3015981-A1 (DE)
Title: Sintered electrodes mfr. - by high-speed inductive heating of powder layer on carrier band
Inventor: ALF FRITZ DIPL ING
IPC: H01M4/04
Filed: 1980-04-25
Abstract: High-porosity sintered electrodes for electrical accumulators consist of metal particles which have been sintered together to a porous framework on a carrier band at a high temp. The band which carries a powder layer is briefly heated inductively in a magnetic field to the sintering temp. The temp. in the band carrier is kept at a higher level than in the powder layer. A preheating stage in a continuous radiator-equipped furnace preheats the band to not more than 300 deg.K below sintering temp. In the second stage, inductive heating raises the temp. in 2-5 seconds to the sintering temp. If a hairpin inductor is used, the high-frequency generator feeds it at 300-600 kHz. A surface-type of inductor would require 1-10 kHz. The result is a uniform porosity of the layer throughout the entire cross-section and a good adhesion of the powder particles on the carrier surface.

Title: Diesel engine with two sets of cylinders - has resonant air intakes arranged for different characteristics to reduce low load losses
Inventor: STOCK DIETER DR ING
IPC: F02B27/00
Filed: 1980-05-10
Abstract: The six cylinder engine has the cylinders arranged in two sets (I,II). One set (I) operates continuously while the other (II) operates only at high loads. Each set has its own air inlet (8,13) with a header (10,15) and resonant tubes (11,16) to the individual cylinders. The headers and tubes are so proportioned that the set of cylinders operating continuously produces a high torque at low speeds in the low load range while the other set of cylinders has its inlet (15,16) arranged for high loads at high speeds. This reduces the friction losses in the shut off set (II) which the continuously running set (I) has to overcome at low loads.

Title: Reinforcing fibres for mineral building material - comprising flax stems opened and impregnated with lime water
IPC: C04B16/02
Filed: 1980-03-04
Abstract: Reinforcing fibres for a mineral construction material contg. a hydraulic binder are prepd. by cutting to length vegetable fibres esp. stem fibres such as flax as first opened along the capillaries, then dried, impregnated with a suspension, pref. of lime in water, a milk of lime, dried again then satd. with a soln. of soluble glass contg. formaldehyde. Used for reinforcement of pipes, boards or profiles, etc. esp. finials and angle mouldings. The fibres are used as a replacement for toxic asbestos. The lime mineralises the fibres so that they have the physical properties of asbestos without the toxicity, and they are equally resistant to industrial gases, to formation of fungi, attack by insects and putrefaction, and have the high resistance to fire possessed by asbestos. The fibre board made from the fibres does not efflurescesce, nor does it contain 'packets' of unmixed fibres as occurs with asbestos. Improved mechanical properties of asbestos board and lack of problems exhibited by glass fibre reinforcement are further advantages together with the fact that it can be locally grown, reducing transport costs.

Title: Drive for a scattered ray grid
Inventor: ARAUNER ALFRED ING GRAD
IPC: A61B6/06
Filed: 1981-06-12
Abstract: The invention relates to a drive for a scattered ray grid (8) in which the scattered ray grid is moved starting with a high, progressively decreasing speed. When producing X-ray photographs, the scattered ray grid preferably attenuates the scattered rays by virtue of its shaft-like structure. In order to blur the structure of the scattered ray grid on the film, the scattered ray grid is moved at a variable speed during the taking of the photograph. For this purpose the invention provides for the free end of a lever (4) which can be rotated about a fulcrum (5) to be displaceable along a guide track (3) which can be rotated about a second centre of rotation (2) at an approximately constant speed and is coupled to the scattered ray grid. In addition, the distance between the fulcrum (5) and the centre of rotation (2) of the guide tack (3) can be smaller than the length of the lever (4) between its fulcrum (5) and its engagement point on the guide track. A drive according to the invention for a scattered ray grid is suitable in particular for medical and technical X-ray examination equipment. <IMAGE>
