Title: Spherical luminescence diode prodn. using selective epitaxy - uses mask exposing locations for producing notches in substrate
Inventor: GRAMANN WOLFGANG ING GRAD
IPC: H01L21/20
Filed: 1974-09-26
Abstract: The production process of hemispherical luminescence diodes starts with an even number of discs of a semi-conductive, intermetallic compound substrate, heavily doped by a material forming in the substrate a first conductivity. The polished surfaces of the discs are provided with a passivating coating, having mask apertures for selective epitaxy. Thus first flat depressions are formed under the mask apertures on the main surfaces, into which is epitaxially grown substrate material with amphoterically doped pn-junction at temperatures of approximately 800 deg.C. This substrate material is then contacted and the mask apertures are also surrounded by annular contacts, provided with soldering layers. Finally cubes are cut out from the substrate, each containing a pair of diodes and ground into spherical shape.

Title: Safety interlock for remote controlled vehicle - with emergency braking if new command not sent within set time
Inventor: ESCHER ROLAND DIPL ING
IPC: B61L3/12
Filed: 1974-10-22
Abstract: The vehicle is fitted with a safety interlock which requires the driver to operate a switch repeatedly, within set time intervals. Failure to do this results in an optic/acoustic warning, and subsequent failure to operate the switch brings in the emergency braking. If the vehicle is being controlled from a remote command post, e.g. by radio control then a new type of safety interlock is fitted, as part of the command transmitter. This has a counter to monitor the time interval between different commands. If no command change is monitored within the set time interval when a warning is sounded on the controls, followed by an emergency braking signal after a second time interval.
Patent DE-2451071-A1 (DE)
Title: Fasteners for expanded thermoplastic mouldings - for automobile trimmings having latches moved from neutral into active position on fixing
Inventor: KUEPPER MANFRED
IPC: B29C65/56
Filed: 1974-10-26
Abstract: Mouldings of integral expanded thermoplastics, i.e. those in which the foam structure increases in density from the core outwards to a closed skin, and having fastening devices such as hooks or bolts incorporated in them, are arranged so that the fastener is moved when the moulding is put into position from a neutral and inactive into an active stance. In the inactive position, the fastener is completely enclosed by the moulding. Packing is thus facilitated and damage by possibly sharp projections is avoided. There may be an opening in the fastener with a passage in the moulding leading to it, through which a wedge is inserted to lift a latch into the locking position, or a plunger may be present in the moulding which deflects a leaf spring on assembly. Makes unnecessary the expensive task of trimming away spew, and gives clean and neat contact surfaces between the moulding and the structure to which it is attached.
Patent DE-2456038-A1 (DE)
Title: Twin compressor control method - switches from continuous to intermittent running, or individual cut-out, dependent upon air requirement
Inventor: LUDIN KARLFRIEDER
IPC: F04B41/06
Filed: 1974-11-22
Abstract: A method for controlling a rotary compressor set, in which, dependent on the momentary pressure requirements related to the rated delivery power of the compressor, the unit is automatically switched over from continuous operation with suction throttle control to intermittent running, or, alternatively, from intermittent running to continuous operation. The switch over process depends upon a comparison of the time lapse of an intermittent operating condition with a time value determined by the permitted switching frequency of the drive motor. The set comprises twin compressors, separately driven, delivering into a common air receiver. Where the compressed air requirement falls below 50% of the nominal rated delivery, the first compressor, after the second unit has been switched off, is either throttled or placed into intermittent operation, dependent upon the air requirement.

Title: Anthraquinone prodn - by dehydrogenation of naphthoquinone-butadiene adduct with oxygen in organic base
Inventor: SAKUMA KIYOSHI
IPC: C07C46/02
Filed: 1974-12-21
Abstract: Anthraquinone prodn. by dehydrogenation of a Diels-Alder adduct of napthoquinone and butadiene is improved by dissolving the adduct in an organic base and carrying out oxidising dehydrogenation with molecular oxygen or an O2-contg. gas mixt. Anthraquinone crystallizing from an organic medium forms larger and better developed crystals than in the known process carried out in an alkaline aq. medium (moreover, the disposal of the latter is troublesome). Thus, the sepn. of the product by filtration is facilitated, and improved purity is attained. When phthalate anhydride is present in a significant amt. (it is formed as a by-product during the oxidation of napthalene to naphthoquinone), the process can still be carried out under the condition that an organic base is selected which does not react with phthalic anhydride.

Title: Flexible underground irrigation pipe - has continuous underneath surface and top surface with slits in which are inserted sealing rings
Inventor: HOELTER HEINZ
IPC: A01G25/06
Filed: 1975-10-03
Abstract: The flexible irrigation-pipe can be laid underground at a depth of, for example, one metre, and can be covered in straw, coconut matting and/or plastic fabric. The underneath side of the pipe is preferably continuous, without holes, but the top side of the pipe has slits or holes in. The openings in the top side of the pipe have sealing-rings in, with the result that the water-flow inside the pipe produces a static, pre-set pressure. When this pre-set pressure is exceeded, the water is released up to the soul surface and thereby to the plants, through teh sealing-strips which can also be made of porous material. The water is thereby uniformly distributed along the entire irrigation system, and released in equal quantities from the pipe. The static water pressure guaranteed can be 0.1 atmospheres.
