Title: Watering system for plants in area with impermeable sub-soil - has supply pipes in top soil with drainage pipes in upper regions of sub-soil
Inventor: RUEGGENMANN HEINZ PROF DR ING
IPC: A01G25/06
Filed: 1977-01-18
Abstract: The system is used for watering soils where, below the top soil, there is a solid relatively water-impermeable layer. Below the surface in the top soil layer, there are supply pipes at the plant root depth. The take-off pipes (6) of a drainage system are arranged at a distance below the supply pipes (7) but above the impermeable layer (1). The take-off pipes (6) lie on the surface of the impermeable layer, which has a shape forming flat channels. The take-off pipes (6) are arranged at the deepest point of the channels. The perforated layer (7) has a good capillary water conductivity and there is an intermediate water permeable layer (2) with good drainage properties.

Title: Valved sack extraction mechanism from magazine - has end portion sucked out before mechanically gripping for further extraction
Inventor: HERDA DIETER ING GRAD
IPC: B65B43/26
Filed: 1977-02-02
Abstract: The mechanism extracts a valved sack from a magazine and prepares it for fitting over a filling machine spout. The foremost sack is sucked out of the magazine and turned into the filling position. Only an end portion of the sack (2) is sucked out of the magazine (1), after which this portion is mechanically gripped and extracted in the lengthwise direction of the sack. It is then turned through roughly 180 deg., and supported on its rear side in the final position. Suction is then applied to its front for further preparation.

Title: Plastics tooth picks in upright row held together by strip - have constriction at base for easy severing and lengthwise ridge and groove for stacking
Inventor: HAMMESFAHR BERND
IPC: A61C15/02
Filed: 1977-08-19
Abstract: Plastics toothpicks are arranged upon a carrier strip with wich they form a unitary set. The point(s) where the toothpick(s) join(s) the carrier strip is intended to facilitate severing the former from the latter and is therefore suitably contoured during the injection-moulding of the set. The carrier strip has a recess(es) along its otherwise straight edges, or holes traversing its thickness. The side faces of the toothpick have ribs and/or grooves contoured and positioned so that they fit into one another when several toothpicks are stacked high.

Title: Solar cell prodn. - by depositing semiconductor pn junctions in anodised aluminium pores during electron beam irradiation
Inventor: HERTEL KARL
IPC: H01L31/043
Filed: 1977-09-17
Abstract: A solar cell is produced by coating an Al carrier plate in an anodizing process with a porous transparent aluminium oxide layer. Its through pores are then filled out by vapour deposition of a sequence of layers of a p-type semiconductor and a metal layer in a vacuum while irradiating the plate by an electron beam. A final transparent contacting layer forms the counter contact to the Al plate. The electron beam charges the anodized layer to prevent undesirable deposition. The new solar cell has a much better conversion efficiency because use is made of the pores throughout their depth.

Esp. the treated soln. is satd. with air under excess pressure, then the pressure released so that the flocs of Al(OH)3 are carried to the surface as a thin layer by air bubbles. Reduced requirement for chemicals is obtd. c.f. use of Al sulphate only. The flocs can be sepd. by flotation as well as sedimentation.

Title: Monitor for continuous fluid flow through transparent tube - uses light detectors and differential amplifier flow disturbance detector
Inventor: LATERNSER IVO
IPC: G01F23/292
Filed: 1978-04-26
Abstract: The device is for monitoring the continuous flow of a fluid through a transparent tube and produces a warning signal when the flow is disturbed.

Title: Removal of PVA from waste water - by irradiation with energy-rich radiation pref. combined with inorganic salt addn.
Inventor: FISCHER KLAUS DR
IPC: C02F1/30
Filed: 1978-07-29
Abstract: PVA is removed from waste waters by irradiation with energy-rich radiation, e.g. gamma- and electron radiation. Ratiation dosage may be 0.5-10 (0.75-2) x 104 J/kg. waste water to remove PVA in 0.005-20 (0.05-5) wt. % concn. Irradiation is continued until solid PVA is pptd. and can be filtered off. PVA pptn. by radiation is increased by adding an inorganic salt before or during irradiation, whereby radiation dosage can be decreased. The process is used for purifying waste water obtd. in desizing textiles sized with PVA. Elimination is >50% and can reach 100%. High elimination proportions can be achieved with the addn. of only 1 inorganic salt, e.g. Na2SO4.

Title: Dry electrolytic capacitor - produced by fluidised bed dip coating and partial water bath immersion
Inventor: BUB HUBERTUS
IPC: H01G9/00
Filed: 1978-08-05
Abstract: Solid-electrolyte capacitors are produced by suspending the sintered valve metal bodies in a line at equal distances from their anode wires. They are dipped in an organic powder as used for fluidised bed dip coating or a powder suspension to coat them all over. By dipping partly into a water bath, the coating is removed except a cap which forms a cone around the anode wire when heated. This applies a plastic cone to a large number of sintered valve metal bodies in one single operation. It saves much time compared with the application of a drop of epoxy resin from a cannula.

Title: Fireproof door closure for large building - comprises elastic and flexible fireproof fabric mounted within metal frame
Inventor: HOELTER HEINZ ING GRAD
IPC: E06B3/72
Filed: 1978-08-21
Abstract: The fireproof closure has an insulation layer consisting of a fabric of ceramic or glass fibre attached to a metal frame and covered by facings. The insulation layer may consists of sheets of fabric made of titanium-treated ceramic or glass fibre joined together by needlelike fibres of similar material extending through an intermediate layer of fireproof particulate material. The multi-layer fabric may also be used as a fire-fighting blanket. The fire-resistant properties of the door can be improved further, if the insulation layer comprises at least two fabric layers. Those fabric layers are specially linked or felted with each other through a granular heat-insulating material. The thus formed needle-like fibres hold the layers together and prevent eht granular material from shifting.

Title: Camera lens focussing device - uses strip raster movable transversely to optical axis and photodetector coupled to two LEDs
Inventor: STEMME OTTO DIPL PHYS DR
IPC: G02B7/36
Filed: 1978-09-07
Abstract: The focussing device directs an image of the object to be photographed onto a photodetector via a strip raster, which is movable in a direction perpendicular to the optical axis. The output signal from the photodetector is used for controlling two light elements, e.g. l.e.d.s. The strip raster has between 5 and 8 lines, while the photodetector, e.g. a silicon diode, is coupled via a control amplifier and two series difference circuits to the two light elements. A further amplifier may be coupled between the difference circuits, with a l.e.d. for displaying a preselected focus.

Inventor: VOSS GUNTHER M
IPC: B63B35/79
Filed: 1978-10-11
Abstract: The sailboard is conventionally shaped, but made up of an upper (2) and a lower (3) portion, formed to enclose a U-shaped chamber symmetrical about the centre line, ending in openings through the transom. The legs (4, 5) of the U provide stowage space for mast, sails, etc. The cross-tube (6) is foam-filled to increase buoyancy. Snap closures (7, 8) which may be lockable, seal the openings in the transom. The U-legs are spaced to leave room between for mast mountings, and slots for hinged dagger-board and skeg. The latter is linked in opposition to a retractable transport pulley (15).

Filed: 1978-10-14
Abstract: In the cycloid drive system for the weft insertion lances of a loom, there is a control gearing assembly. This has a drive crank in a dual-crank layout which gives a deviation from a pure rotation on each rotation of the drive unit. The design gives a variable speed action for the lance so that it moves relatively slowly on picking up a weft, and rapidly through the shed. It also allows different lance speeds on insertion and withdrawal.
