Patent EP-0321791-A3 (EP)
Title: Magnetic domain strain gage
IPC: G01L1/12
Filed: 1988-12-08
Abstract: A magnetic domain strain gage (20) and method 
of digitally measuring strain or fatigue within a 
ferromagnetic material (22) by measuring the time required 
for an increasing magnetizing force to cause magnetic 
domains to flip orientation in a ferromagnetic material 
(22) as a function of strain or stress within the 
material. The magnetic domain's maximum rate of flip is 
measured as a time differential by a high frequency 
digital oscillator (18) which provides a digital signal 
indicative of the strain thereby providing increased 
compatibility with digital data acquisition systems and 
having a superior signal to noise ratio in comparison with 
present low signal level analog resistance strain gages.

Title: Method of and apparatus for eliminating interblock distortion due to compressed image data
IPC: G06T9/00
Filed: 1989-04-04
Abstract: Interblock distortion often appears on a boundary of 
pixel blocks in a reproduced image produced from compressed 
image data. The interblock distortion is eliminated by 
correcting a density distribution in the reproduced image. 
First, an average density (A ij  of a selected pixel block 
(B ij ) is computed. Second, a standard deviation (σ ij ) of a 
density distribution in the selected deviation is computed. 
If the standard deviation is equal to zero, correction value 
distributions Δf m , Δf n ) along a main scanning direction and 
a subscanning direction are obtained. Finally, corrected 
density distribution (f mn ) is obtained as a sum of the 
average density and the correction value distributions.

mit einer Filterdrossel (FL) eines 
Tiefpaßfilters und über eine zwischen Hauptschalter (SCH1,2) und 
Filterdrossel (FL) angeschlossene Freilaufdiode (FD) mit dem mittleren 
Ausgang (P8) verbunden sind, während der mittlere Ausgang einer­
seits direkt mit dem sekundärseitigen Sternpunkt (P1) des Trans­

integralen Bestandteilen der Tiefpaßfilter, so daß an dem 
Transformator nicht mehr die hohen Schaltfrequenzen anliegen, 
sondern nur noch das niederfrequentere Eingangssignal, was 
eine erhebliche Reduzierung der Verlustleistung in den 
Aufbaukapazitäten des Transformators zu Folge hat. Zur 
Reduzierung sogenannter Unterstrichverzerrungen ist jeder 
Freilaufdiode (FD1, FD2) jeweils ein 
Hilfsschalter (SCH3,4) parallel geschaltet, 
der im Gegentakt zu dem zugehörigen Hauptschalter (SCH1,2) betrieben 
wird.

Title: Commercial message timer
IPC: H04N5/45
Filed: 1989-10-19
Abstract: A commercial message timer (114), when enabled by a user, stores data indicative of a first tuned station and begins timing a predetermined time period. Upon expiration of the time period, the first tuned station is automatically reselected if it had been deselected after the timer was enabled. In this way a user can avoid a commercial message on a first channel by setting the timer and scanning through other channels, and yet have the receiver return automatically to the first channel at the end of a time period substantially equal to that of a typical commercial message. In another embodiment employing PIX-IN-PIX circuity, the subject apparatus is responsive to an occurrence of (1) enabling the timer and (2) changing channels, in that order, for automatically moving the desired channel to the inset position. In response to the expiration of the timer period, the program displayed in the inset position is automatically returned to the main display position.

Patent EP-0342805-A3 (EP)
Title: Data-processing sub-system operating method
IPC: G06F3/06
Filed: 1989-04-26
Abstract: A state of operation is established in accordance with 
rules for a peripheral sub-system which enables reduced channel time 
for executing ensuing related channel commands of the same channel 
program. In a peripheral data-storage sub-system, a set of rules of 
operation are established. Each rule sets forth a predetermined set of 
sequences of channel commands during any chain of channel commands 
(channel program) which predict ensuing channel operations in channel 
program currently being executed. Once any rule is satisfied, a state 
of operation is established in the sub-system for responding to 
ensuing channel commands in the same channel program and which relate 
to the channel commands set forth in the rules. So long as such 
related ensuing channel commands continue or until the end of the 
channel program the state of operation is maintained in the 
sub-system. During the state of operation, responding to the ensuing 
commands is speeded by performing preparatory sub-system operations 
before executing the ensuing channel commands. In a search for a 
desired record function, the state of operation causes data to be next 
searched to be staged to an electronic buffer such that the ensuing 
channel commands are executed at electronic speeds rather than related 
to the latency time of disk recorders.

Title: Edible spread
IPC: A01J15/12
Filed: 1990-09-28
Abstract: Edible spreads are prone to microbiological spoilage by a number of organisms, including molds and bacteria as well as by physical changes occurring on storage. While the growth of these organisms and consequently the onset of spoilage can be inhibited by the use of preservatives, some consumers find preservatives unacceptable. We have determined that in edible fat products wherein the fat phase comprise a homogeneous dispersion of fine crystals and in which the fat phase is essentially free of crystalline aggregates spoilage is greatly reduced. Anhydrous products can be produced by melting the fat, substantially in the absence of an aqueous medium, cooling the melted fat to a temperature at which partial crystallization occurs, homogenising the partially crystallised fat, and, cooling the homogenised fat to further crystallise the fat. By means of a modified process it is possible to produce comprising 50-60% fat phase, 40-50% water phase, 0.1-1% lecithin, 0.01-1% salt, being essentially free of monoglycerides, proteins and sorbate salts, which are stable on storage.
