Patent EP-0348587-A3 (EP)
IPC: H02H3/24
Filed: 1989-01-13
Abstract: Die Erfindung betrifft eine Schaltungsanordnung zur Überwachung 
eines aus einem integrierten Schaltkreis aufgebauten elektro­
nischen Gerätes (3) gegen Betriebsstörungen, welches aus einem 
wiederaufladbaren Akkumulator (1) betrieben wird. Hierbei ist es 
erforderlich, daß bei einer Unterschreitung einer vorgegebenen 
Betriebsspannung für das zu versorgende elektronische Gerät, die­
ses vom Akkumulator (1) abgetrennt wird. Eine derartige Abtren­
nung soll nicht nur beim Vorliegen einer erreichten Tiefentlade­
spannung des Akkumulators (1), sondern auch im Hinblick auf 
Kurz- und/oder Kriechschlüsse und auf einen Mindestspannungs­
pegels der Betriebsspannung erfolgen.  
Die Erfindung löst diese Aufgabe dadurch, daß die Überwachungs­
einrichtung (2) einen als Komparator geschalteten Operations­
verstärker (4) aufweist, der mit seinem Ausgang an ein Halb­
leiterschaltelement (10) angeschlossen ist, welches wiederum 
zwischen dem Akkumulator (1) und dem elektronischen Gerät (3) 
in Reihe geschaltet ist, wobei zwischen dem Gerät (3) und dem 
Halbleiterschaltelement (10) in Sperrichtung zum Gerät (3) eine 
Diode (11) an den invertierenden Eingang des Operationsver­
stärkers (4) geschaltet ist.

Title: Device for reading positional information on photographic films
IPC: G03B21/11
Filed: 1989-04-12
Abstract: A device for reading positional information on 
photographic films used for reading, when a photographic film (18) 
is being fed, pieces of positional information (18A) provided on the 
film in a predetermined order and in correspondence with a 
plurality of image frames recorded on the film in the 
longitudinal direction thereof. The device is designed to 
determine whether or not any piece of positional information 
read has been erroneously read; when it is determined to have 
been erroneously read, the device selects the correct piece of 
positional information on the basis of those pieces of 
positional information which are adjacent to that piece of 
positional information determined to have been erroneously 
read. Thus, even if an error has occurred in the reading of 
positional information, the subsequent processes need not be 
interrupted.

Title: Molten metal pouring nozzle for continuous casting machine having endless-travelling type mold
IPC: B22D11/06
Filed: 1989-06-13
Abstract: A molten metal pouring nozzle for a continuous 
casting machine having an endless-travelling type mold, 
wherein the endless-travelling type mold is formed with 
two pairs of opposing wall members endlessly travelling 
in the same direction and at the same speed, and one end 
of the pouring nozzle is connected to a tundish for 
receiving molten metal, and the other end of the pouring 
nozzle is inserted into the mold. The molten metal pour­
ing nozzle of the present invention comprises a nozzle body 
made of a refractory and a flow regulator made of a 
refractory. The nozzle body (14, 20) has a bore (1a, 3a), 
through which molten metal flows, along the axial line 
thereof, and the sectional area of the downstream end 
portion of the bore (1a, 3a) becomes gradually larger 
toward the downstream end thereof. The flow regulator 
(15, 18) is arranged at the center of the downstream end 
portion of the bore (1a, 3a) of the nozzle body (14, 20). 
The flow regulator (15, 18) forms, in cooperation with 
the bore (1a, 3a), a path for molten metal, by which 
molten metal flowing through the bore (1a, 3a) impinges 
 
 
against the inner surface of the mold, near the downstream 
end of the nozzle body (14, 20).

Title: Accousto-optic tunable filter
IPC: H01S3/106
Filed: 1989-02-08
Abstract: An acousto-optic tunable filter, for laser tuning, 
comprises an acoustic transducer (13) connected to one 
face of an anisotropic crystal (9) or Bragg cell which is 
cut at such an angle relative to its optic axis that an 
acoustic wave projected into the crystal normal to the 
said face causes wavelength-specific diffraction of an 
incident optic wave (from laser amplifying element 2) 
which nearly, but not completely, satisfies the parallel-­
tangents phase matching condition, thus preserving a 
substantial angular field of view, the said angle also 
being such that the said diffraction is polarisation-­
insensitive.

Filed: 1989-09-20
Abstract: A command is decoded in a unit (31) to provide bus-­
output-control information concerning a common bus 
busy state, and the existence of the command or 
data. When the common bus (34) is not available to the 
unit, the decoded bus-out-control information, command

Abstract: An electrostatic latent image developing device 
(28) of the type having a regulating member (28c) urged 
resiliently towards a surface portion of a developing 
roller (28b) of the device (28) so that an edge (28c₃) 
of the regulating member (28c) nearest to the said 
surface portion and parallel thereto serves to regulate 
the thickness of layer of toner particles carried on 
the roller (28b) when the device (28) is in use is 
characterised in that the angle of the cross-section of 
the said regulating member (28c) at the said edge 
(28c₃) is in the range from 90° to 180°. Alternatively, 
the edge (28c₃) may have a rounded cross-section. In 
each case, the edge is less susceptible to damage and

Title: Method and apparatus for thermal conversion of organic matter
IPC: C10G1/10
Filed: 1990-04-24
Abstract: A method and apparatus for the thermal conversion of organic 
waste materials includes a tank having a molten metal bath, 
preferably lead, through which apertured containers are trans­
ported by primary conveyer members in a plane intermediate two 
arrays of heating devices. Buoyancy of the waste-filled contain­
ers is resisted by abutment members within the tank while align­
ment elements on the containers prevent the containers from 
becoming askew during their travel through the tank. The abut­
ment members may comprise fixed rails or secondary conveyor 
members spaced atop the primary conveyor members. Agitation 
devices within the tank assist in maintaining maximum heat dis­
tribution throughout the bath. Produced hydrocarbons are col­
lected by a main hood overlying the majority portion of the tank 
bath surface while separate shroud assemblies overlie other, 
individual isolated bath surfaces at the entrance and exit of the 
tank. Inorganic and/or products not converted by the elevated 
temperature of the bath (over 650 degrees F), accumulate on the 
surface and are periodically removed by a skimmer apparatus, 
communicating with the exterior of the hood. A continuous proc­
ess is achieved by utilizing conveyors to deliver and retrieve 
the containers to and from the tank, respectively.

Title: A machine for processing haulm-like crops
IPC: A01D43/10
Filed: 1992-06-05
Abstract: A machine for processing, more specifically mowing and 
crushing, haulm-like crops, is provided with crusher rollers 
(35, 36) having adjacently and oppositely arranged conical 
portions (46, 47) with oppositely directed conical 
variations. This achieves that the mown haulms are conveyed 
in different directions through the crusher rollers (35, 36), 
so that the haulms leaving the crusher rollers (35, 36) in a 
flow are interweaved. This provides a swath having a coherent 
crop structure, as a result of which the swath is easier to 
handle and less losses will occur during the picking-up.  
     In addition, the crusher means (29,64) are constructed in such a 
way that the crop will be put onto the ground in a number of 
tunnel-like configurations lying side by side on the ground and 
extending in the direction of operative travel.
