Title: Electric generator provided in ski binding - charges battery that powers electronically-controlled safety release including force sensors
Inventor: EIBL VOLKER DIPL ING
IPC: A63C9/08
Filed: 1979-10-08
Abstract: A safety ski binding includes force pick-ups for generating electrical signals in response to forces and torques acting on the skier's leg. An electronic integrated circuit initiates operation of a releasing mechanism by a tripping signal generated in response to the occurrence of dangerous forces or torques. A rechargeable battery (B) for feeding the circuit is supplied with charging current from a generator formed by relatively movable parts connected to a member of the ski binding and to a surface of the ski. Pref. the movable parts consist of one or more layers of piezoelectric zirconate-titanate ceramic material to which pressure is applied by a pin secured to the ski. Provision of the rechargeable battery ensures that virtually no maintenance is required.

Title: Contactless rotating shaft seal - has auxiliary fluid e.g. water fed by pump into gaps between labyrinth passages
Inventor: ULRICH HELMUT DIPL CHEM
IPC: F16J15/44
Filed: 1979-10-09
Abstract: The sealing system is for rotating shafts and comprises at least two labyrinth seals (6,8) arranged one behind the other in the direction of sealing. Between the seals, an auxiliary medium e.g. water is introduced under pressure at the same level as that applicable in the chamber to be sealed.

Inventor: GRAESSINGER HELMUT
IPC: A01K1/06
Filed: 1979-11-06
Abstract: For the standing surface of the shut-in grid there is provided in each case a fixed shut-in bar (2) which delimits the standing area and is in functional combination with a movable shut-in bar (3), said bars forming together the shut-in opening (4).

Title: Composting municipal clarifying sludge - after adding comminuted waste paper shreds as carbon-carrier, swelling and water-extn., facilitates printers ink and heavy metals removal
Inventor: KNEER FRANZ XAVER
IPC: C05F7/00
Filed: 1980-04-21
Abstract: In composting municipal clarifying sludge, waste paper is used as the exclusive C-carrier for setting a C/N ratio suitable for rotting. After comminuting to irregular coarse shreds, the waste paper is added to the non-dehydrated clarifying sludge until C/N ratio is 20:1 to 25:1. The sludge obtd is then swelled 2-10 hrs., dehydrated to 30% solids content and composted. Waste paper is cheaper and more easily available than the previously used sawdust. The paper shreds and liq. sludge form an easily dehydratable mixt., yielding a higher solids content. In water-extn., the paper shreds absorb suspended materials and act as flocking auxiliaries. The dehydrated mixt can be disposed of as pellets or composted. Printers' ink on waste paper can be removed by standard flotation e.g. with 3% resin soaps and 1.5-3% cerosine. Heavy metals in sludge can be pptd mechanically, electrolytically and/or chemically. Fresh compost is pref added to the sludge before mechanical water etxn.

Title: Deactivator for security strip on saleable goods - has deactivating coil pulsed from thyristor controlled capacitor discharge
Inventor: KLINKHARDT ERHARD
IPC: G08B13/24
Filed: 1980-04-24
Abstract: The deactivator circuit consists of a transformer (7) which, via a rectifier (8) and a resistor (9), feeds the oscillatory circuit made up of the deactivating coil (3) and a capacitor (10). The deactivating coil (3) is in series with a thyristor (11), the gate of which, is fed via two microswitches (12,13) from one side of the circuit rectifier (8). When the microswitches (12,13), which are in series, are closed, a magnetic field builds up in the deactivator coil (3) in less than a millisecond, due to the discharge pulse of the capacitor (10). Sharply defined magnetic zones arise, which cannot be changed by incorrect use of the deactivator. Other models of strip deactivator can be constructed for books, records, music cassettes. In the case of the latter, the form is such, that the recording on the tape itself is not damaged during deactivation of the strip.

Title: Integrated semiconductor circuit prodn. - by electron bombardment, UV irradiation and alkali treatment of a phenolic condensation resin having a photosensitive lacquer
Inventor: OLDHAM WILLIAM GEORGE PROF
IPC: G03F7/20
Filed: 1980-07-25
Abstract: Substrates are embossed with relief structures, as in the mfr. of semiconductor circuits, by employing radiation-sensitive lacquers based on phenolic condensation resins, wherein the photoactive components of the lacquer are chemically decomposed by light and subsequent treatment of the lacquer layer results in a differential capacity of the irradiated zones to dissolve in relation to the amt. of humidity in the radiation atmos. The light-sensitive layer on the substrate is acted upon in vacuum by beams of electrons which correspond to the relief structure that is to be obtd, and the photoactive in the respective zones. The whole is then subjected to UV radiation in a humid atmos. thus decomposing the photoactive components in those zones of the lacquer coating which not acted upon by the electron beams. Finally the whole is treated in a developer, dissolving the irradiated zones that were not bombarded with electrons, while those zones that were bombarded are not so dissolved in the lacquer layer. Pref. the photosensitive lacquer layer has substd. diazo-o-naphthaquinone as the photoactive component in a phenolic resin of the Novalak type. The developer is, more specifically, an aq. alkaline developer soln. with or without an organic ammonium base. Electron bombardment may be dosed at 20-30 micro C per square cm. and UV irradiation in a humid atmos. can be to the order of 100-1,000 mJ per sq.cm. The components may be employed in the manner of a negative resist for electron bombardment. Highly soluble negative electron lacquer that is very resistant to corrosion can be used for the mfr. of conductor paths in integrated semiconductor circuits of 1 micron magnitude.

Title: Conveyor moving spinning cops to bobbin winder - has cops grippers and cutters for trailing thread ends traversing spaces between grippers
Inventor: SCHREIBER MANFRED
IPC: B65H67/06

Title: Fuel container for IC engine - has fuel circulated back to tank by pump to prevent overheating
Inventor: SCHWANDER DIETER
IPC: F02D33/00
Filed: 1980-11-20
Abstract: The fuel container has a float operating a fuel inlet valve (6) and a fuel outlet valve (7). A pump (12) pumps fuel from the fuel tank (10) to the inlet valve. The outlet valve returns fuel to the tank. The returned fuel flows through a heat exchanger (9) in the main tank. The fuel container may be located in the vehicle's carburettor. Circulating the fuel through the container in this way prevents it from overheating-- i.e. prevents its temp. rising above boiling point.

Patent DE-3116927-A1 (DE)
Title: Slippering and brushless generator (dynamo)
Inventor: ROTH ERNST DIPL ING
IPC: H02K11/00
Filed: 1981-04-29
Abstract: The generator according to the abovementioned invention, predominantly provided for use in motor vehicles, is a three-phase or AC generator (alternator) having semiconductor rectification connected to it. The rotating magnetic field which is necessary for excitation (energising) is not produced by windings through which current flows and which are installed in the rotor but by permanent magnets which are likewise installed there, as a result of which the dynamo requires no slipperings or brushes for supplying the excitation current. The power generation is controlled (regulated) via a shunt winding which is wound in the same sense as the main winding and through which direct current flows, and whose magnetic field is combined with the magnetic field induced by the rotor. In the half cycle in which the magnetic fields are additive, magnetic saturation is reached in the iron of the generator, during which no power is generated since there is no change in the induction, to be precise in a portion of the half cycle which becomes larger as the current intensity in the shunt winding increases. As a result of the absence of slipperings and brushes, a generator of this type requires no maintenance. The attached outline diagram shows an exemplary embodiment of an AC generator. <IMAGE>
