Patent EP-0247554-A3 (EP)
IPC: H04B15/00
Filed: 1987-05-23
Abstract: Zur Ausschaltung von Potentialdifferenzen zwischen 
dem speisenden Netz-Primärstromkreis bzw. dem gekop­
pelten Sekundärstromkreis und den zu linearisierenden 
weiteren Stromkreisen, sowie innerhalb dieser Stromkreise 
von elektronischen Geräten, bei denen die Linearität von 
Signalen technisch von Bedeutung ist bzw. Potentialdiffe­
renzen störend wirksam werden.  
     Hierzu werden die Massepunkte der zu linearisieren­
den Stromkreise mit der sogenannten Potentialausgleichs­
schiene oder dem Haupterder bzw. einem äquivalenten Er­
der des speisenden Netz-Primärstromkreises der elektri­
schen Netzstrom-Abnehmeranlage leitend verbunden.  
     Zu dieser Verbindung, die einen möglichst geringen 
elektrischen Widerstand aufweisen sollte und die insbeson­
dere einen sehr viel geringeren Widerstand hat als der so­
genannte Erdschutzleiter, der üblich installierten Licht-­
Steckdosenleitungen mit 1,5 mm² Querschnitt, können auch 
metallene Rohre von Wasser und Heizung, des Gebäudes 
innerhalb dessen die Erfindung angewandt wird, als leiten­
de Verbindung mit eingeschlossen werden.  
     Die Erfindungsbeschreibung erläutert das Anwen­
dungsbeispiel Verstärker und Lautsprecher.

IPC: G11B27/029
Filed: 1987-04-09
Abstract: An electronic editing system utilizes time 
code signals (TTC1, TTC2) for detecting color frame phase of video 
signals reproduced by a playback-side video tape 
recorder (40) and by a recording-side video tape recorder (42). 
In order to enable this operation, color subcarrier 
phases are identified by a frame data of the time code 
signal during test mode operation. In the editing 
operation, the color subcarrier phases of the video 
signals of the playback-side video tape recorder and the 
recording-side video tape recorders are derived on the 
basis of the time code signals at editing points. The 
utilizing the color subcarrier phases identified by 
locking a color framing pulses (CFP1, CFP2) of the video signal with 
a reference synchronizing signal (REF), based on which a 
reference color frame phase can be derived, detecting 
difference of phase between the time code signal and the 
color framing pulse, and detecting difference of phase 
between the color framing pulse and a color frame phase 
of the video signal on the video tape.

Abstract: An electrical to fiber optic conversion unit 
for use in a fiber optic transmission link includes a 
ferrous metal chassis with an open front end for 
receiving a plurality of conversion modules and power 
supply or test modules. The conversion module includes 
circuitry for converting electrical signals to fiber 
optic signals and is constructed of a multi-layer 
printed circuit board having top and bottom layers 
substantially covered with a non-current conducting 
chassis ground. The several internal layers of the 
conversion PC board include two signal layers for 
interconnecting components on the board, with the 
signal layers being separated by a power distribution 
layer and a interconnect layer for connecting com­
ponents on opposite ends of the board. The multi-layer 
PC construction suppresses RF noise from the conversion 
module providing that the front panel of the module may 
be left uncovered while still achieving very low levels 
of RF emission.

Title: Safety apparatus for electrical power supply cables
IPC: H02H3/17
Filed: 1988-10-19
Abstract: The present invention relates to apparatus 
which acts to prevent flow of electrical current in an 
electrical power supply cable when the cable is dam­
aged, or disconnected, at a part of the cable remote 
from the power source.  
     A transmitter is provided for connection to the 
cable at the end remote from the power source, and a 
control means is provided for connection between the 
power source and the cable. The transmitter transmits 
a signal down a cable conductor to the control means, 
which maintains the power supply connected to the 
cable as long as the signal is being received. If no 
signal is received by the control means, perhaps 
because of cable damage or disconnection, the control 
means causes the power source to be disconnected from 
the cable.  
     In a further embodiment, for further safety, a 
second transmitter is also provided with the control 
means for transmitting a further signal down the cable 
to the first transmitter. The first signal will not 
be transmitted unless the transmitter is itself re­
ceiving the further signal.

Title: Software configurable memory architecture for data processing system having graphics capability
IPC: G09G5/36
Filed: 1988-11-23
Abstract: A graphics data processing system memory is 
allocatable by software between system memory and 
graphics framebuffer storage. The memory comprises 
two-port elements connected in parallel from the RAM 
port to a controller connected to a bus, and having 
serial output ports connected to output circuitry to 
map the storage to a display. Corresponding 
locations, relative to element origin, in all 
elements are addressed in parallel as an array. 
Three modes of memory transactions are all 
accomplished as array accesses. First, a processor 
reads/writes the system memory portion by a 
combination of parallel array access and transfers 
between controller and bus in successive bus cycles. 
Second, the controller executes atomic graphics 
operations on the framebuffer storage using 
successive array accesses; third, the processor can 
read/write a framebuffer pixel, by an array access of 
framebuffer storage with masking of unaddressed 
pixels. An interface arbitrates among requests for 
memory access.

Patent EP-0326804-A3 (EP)
IPC: B41J2/045
Filed: 1989-01-07
Abstract: Sowohl für das Schriftbild als auch für die Zuverlässigkeit im 
Schreibbetrieb bei Tintenmosaikschreibeinrichtungen ist es von 
Bedeutung, daß der Ausstoß von Tintentröpfchen aus den einzelnen 
Austrittsdüsen mit gleicher konstanter Geschwindigkeit erfolgt. 
Da hierfür neben den Ansteuerkriterien aber auch Materialeigen­
schaften und Fertigungseinflüsse eine nicht unerhebliche Rolle 
spielen, wird bei den bekannten Einrichtungen für den Tröpfchen­
ausstoß ein Abgleich vorgenommen. Dieser Abgleich wird z. B. 
durch die Einstellung der Impulsspannung mit der die einzelnen 
Antriebselemente eines Tintenmosaikkopfes betrieben werden, 
gelöst. Hierbei ist keine einfache Einstellung vorgesehen, durch 
die ein phasengleiches Austreten der Tintentröpfchen aus den 
Austrittsöffnungen 2 gewährleistet wird. Dieses wird erfindungs­
gemäß dadurch gelöst, daß die als Druckkanäle dienenden Abschnit­
te (17, 18) der Tintenkanäle (3) von den Druckkammern (4) bis zu 
den Austrittsöffnungen (2) und die in die Druckkammern (4) mün­
denden Saugkanäle (21, 22) alle gleich lang ausgebildet sind. 
Durch das phasengleiche Austreten der Tintentröpfchen aus den 
Austrittsöffnungen (2) sind Grafikaufzeichnungen mit einem Fein­
raster bei kompakter Bauweise des Schreibkopfes möglich.

Abstract: A dispensing device of the hand-help pump type has an 
internal piston (21) which is pulled up by a rod (20) passing through 
the piston, which rod is moved by an actuator (19). When the 
contents of the piston are emptied, in order to attach a 
refill, a dog release mechanism operates to release the dogs 
which, in normal use when the device is full, function to 
prevent the piston from being drawn downwardly so that the 
piston can be removed to allow attachment of the refill which 
has a new piston. This Abstract shall not be construed to 
limit the scope of the specification, drawings or claims.

Abstract: A spray calcination process is provided for decomposing a metal 
nitrate solution to form fine grain multicomponent metal oxide powders of 
selected composition of particular utility as superconductor precursor 
powders. Such precursor powders are produced in bulk quantities as high 
purity, reproducible, intimately mixed powders for conversion to high 
temperature superconductors.  
     A metal nitrate solution containing two or more metal constituents in 
a preselected ratio is sprayed as a finely atomized spray into a spray 
calcination zone where it is contacted with a hot gas stream for a 
residence time of less than 15 seconds at a high temperature between 200°C 
and 1100°C sufficient to vaporize the water of the nitrate solution and 
convert the metal nitrates to their corresponding oxides. The formed 
metal oxides are recovered from the gas stream as the desired metal oxides 
powders of selected composition which, where required, may be further 
sintered to form the desired superconducting metal oxide ceramics such as 
the Y-Ba-Cu-O and Tl-Ba-Ca-Cu-O superconductors.
