Title: Grab removing fodder from silos - consists of frame built onto front loader frame of tractor and has tine fork and cutting tool
Inventor: DUECKER JOSEF
IPC: A01F25/20
Filed: 1976-11-19
Abstract: Removal of fodder from flat or mobile silos is by a grab formed by a frame with a ground-side, horizontal tine fork and a cutting tool. This is supported at the end of a beam pivotable by a drive about a vertical pivot shavt. It can be moved up and down by means of a separate drive. The pivot shaft of the beam is arranged in the tractor's travel direction at a distance behind the implements rear wall. A pivot device with a vertical pivot shaft is fitted to the cutting tool and this acts to swivel it out of a position parallel to the tractor's direction of travel into a position which is aligned transversely to the longitudinal centre axis of the beam.

Title: Hardenable, non-volatile, unsatd. polyester resin compsns. - contain liq. linear alkane to give good laminate adhesion in presence of added wax
Inventor: DEMMLER KURT DIPL CHEM DR
IPC: C08G63/54
Filed: 1977-02-12
Abstract: Low-volatile laminatable unsatd. polyester resins, hardenable by standard polymerisation initiators, consists of (a) >=1 ethylenically unsatd. copolymerisable polyester, (b) >=1 ethylenically unsaturated monomer, (c) a waxy material, opt. (d) standard fillers and auxiliaries, and also 0.1-3 (0.5-2) wt.%, w.r.t. total wt. of (a) + (b), of >=1 liq. 5-17 (8-12) C n-alkane, (I), esp. n-octane.

Title: Vacuum cleaner dust bag full indicator - uses temperature dependent resistance which heat up as dust bag becomes full
Inventor: PALMER GERHARD ING GRAD
IPC: A47L9/19
Filed: 1977-06-11
Abstract: The standard for the degree of dirt and dust in the dust bag filter of a vacuum cleaner is determined by the amount of air drawn in through the filter per unit time. An electric temperature dependent is fitted into the flow path of the suction air. This, together with an indicator and/or switch element is mounted in a first branch of an a.c. or d.c. parallel circuit whose second branch consists of at least one comparison resistance. This indicator system is based on the idea of the temperature-dependent electric resistance being cooled by the correct amount of suction air so that when the filter becomes clogged the resistance is cooled to a lesser degree and the ensuing alteration in current can be indicated by e.g. a lamp.

Title: Paint applicator for reproduction purposes - uses spray gun controlled by light beam, converter, and pattern for guiding spray gun control
Inventor: KRAUS ROLAND
IPC: B05D1/02
Filed: 1977-07-14
Abstract: The application process uses spray guns, which are guided automatically or manually at even distance across the work surface for the reproduction. The amount of paint sprayed is controlled by the intensity of the light beam, controlled by a pattern. The beam charges a light-electrical converter, which acts with a control element for the spray gun nozzle. The converter and/or pattern are synchronously moved with the gun movement. With manual control of the gun, the beam is used as a projection beam, which projects the pattern in scale onto the work piece. The stationary converter is electrically connected to the gun control.

Title: Data processor store with voltage failure protection - using voltage discriminator which produces one of two binary signals to show battery voltage relative to specified threshold
Inventor: KRETSCHMER GERHARD ING GRAD
IPC: G06F1/28
Filed: 1978-07-15
Abstract: The data processor store includes a stand-by battery which prevents data errors from being processed, when the voltage supply fails and the stand-by battery voltage is insufficient. The battery voltage is measured against a given threshold sufficient to maintain the stored data and an alarm operated and/or the read-out of data inhibited. A voltage discriminator provides one of two binary signals in dependdance on whether the battery voltage is above or below the given threshold. This signal is supplied to a store providing an output signal for blocking use of the stand-by battery if the voltage is insufficient. A second store receives a binary signal when the mains voltage is reinstated, both stores are coupled via gates controlled by an addressing signal, to a central control.

Title: Test circuit for unattended PBX - uses local programme to respond to test signal from telephone exchange
Inventor: MERZ LOTHAR
IPC: H04M3/32
Filed: 1978-10-11
Abstract: A testing procedure is initiated and carried out for an unattended p.b.x. without the necessity of selecting a local specific number. The p.b.x. has a control unit (ST) which regulates the operation of the selectors and routing circuits (KF) of which one is the incoming line detector (AS) from the telephone system (WA). The control unit also stores a test routine programme (SP). The arrival of a coded number from the system (WA) which has no allocated local connection, for example a zero, is recognised as a test instruction. The controller (ST) routes the instruction direct from the input unit (AS) to the test programme (SP). The programme is then run and information exchanged between local and central exchanges, and evaluated in the latter.
Patent DE-2847874-A1 (DE)
Title: Interferometric method for determination of wave direction - uses two channel method to derive elevation angle from lobe widths and amplitudes of electromagnetic waves
Inventor: UHLMANN MANFRED
IPC: G01S3/46
Filed: 1978-11-04
Abstract: The interferometric method is for determining the direction of incidence of electromagnetic waves and enables use of a considerably more economical system than hitherto. The azimuth angle information is derived from a phase comparison of two neighbouring channels and a defined elevation angle for the incident beam. A radiation characteristic is constructed from the levels in the individual channels and their lobe widths determined. These are used to determine the elevation angle by employing a known relationship between them and the elevation angle. The relationship is determined by measurement or calculation. The method permits the use of a two-channel interferometer without side lobes which would require additional channels. The lobe widths are determined using a Fourier polynomial approximation to a smoothing curve.

Abstract: Sheet metal deformation or plastics technology is applied in production of complete housing units or components with roofing and absorbing planes inclined for solar energy collection. Use is made of quick-laying techniques, without elaborate roof battening and framework, to effect sealed roof skin attachment. A wide range of variety in pitch, height and shape is practicable. Channels, seams, ribs, pleats and other configurations are made, for water drainage, without dirt being collected in the process, and for anchorage of energy-collecting elements on the substructure. This permits inexpensive mass production of prefabricated roofing and solar heat units.
