Patent EP-0254970-A3 (EP)
IPC: H02P7/28
Filed: 1987-07-16
Abstract: Der wichtigste Parameter eines Tachogenerators in einem schnellen 
Servosystem ist die Reaktionsgeschwindigkeit der Tachospannung 
bei Drehzahlveränderungen, denn sie hat zusammen mit dem Motor 
den größten Einfluß auf die Schnelligkeit des Systems. Erfin­
dungsgemäß werden für die Erzeugung einer Tachospannung für 
Antriebe mit einem Gleichstrommotor in Büromaschinen zuerst zwei 
phasenverschobene sinusförmige Codiersignale in einer Schal­
tungsanordnung verdoppelt, so daß hier Codiersignale entstehen. 
Danach werden die vier Codiersignale in einer Schaltungsanordnung 
zu einem Codiersignal mit einer dreieckförmigen Schwingung zusam­
mengefaßt, die dann einem Differenzierglied zur Erzeugung eines 
Signals zugeführt wird. Dieses Signal wird in einer Schaltungs­
anordnung wiederum verdoppelt, so daß zwei Signale entstehen. Aus 
den Signalverläufen dieser beiden Signale wird durch Umschalten 
mit einer Logik jeweils das richtige Teilstück zur Erzeugung der 
Geschwindigkeitsgröße (Ist-Wert) in einer Gleichspannung ausge­
wählt. Für das erfindungsgemäße Verfahren ist nur ein einfacher 
Sensor mit grober Teilung notwendig, was sich günstig auf die 
Sensorkosten auswirkt. Die Schaltungsanordnung hat weiterhin nur 
eine sehr geringe Restwelligkeit der Tachospannung im unteren 
Drehzahlbereich, wodurch sich eine zusätzliche Glättung der 
Tachospannung erübrigt.

Title: Osteogenic growth factors derived from regenerating bone marrow
IPC: A61K38/00
Filed: 1989-06-20
Abstract: To test growth factor production, healing 
bone marrow-conditioned medium was prepared with 
tissue separated from rat tibias during the 
osteogenic phase and assayed for enhancement of 
mitogenic activity in culture of osteogenic rat 
osteosarcoma cells (ROS 17/2). Partial purification 
of healing bone marrow-conditioned medium-derived 
growth factor(s) consisted of gel filtration on 
Sephadex G-25, boiling, chromatography on 
heparin-Sepharose, and gel filtration on Sephadex 
G-75. Mitogenic activity eluted in the void volume 
of the Sephadex G-25 column (mol wt > 5,000). Potent 
activity resolved from heparin-Sepharose with PBS, 
and on filtration by Sephadex G-75 this activity 
recovered in 3 peaks with mol wt estimates of 35,000, 
19,000 and less than 10,000. The partially purified 
factor also showed considerable stimulatory effect on 
DNA synthesis in osteoblastic fetal rat calvarial 
cells and on  in vitro  elongation of fetal long bone; 
it had only a small effect on nonosteoblastic ROS and 
fetal rat calvarial cells. These data indicate that 
healing bone marrow produces growth factor activity 
with a preferential effect on osteogenic cells.

Abstract: There is disclosed a high-speed decoding apparatus 
for use in a flash-type analog-to-digital converter. The 
apparatus disclosed employs an OR gate (70) which follows an AND 
gate (53), which AND gate is conventionally employed in a 
comparator associated with such a converter. The OR gate 
functions to block any dynamic movement of the unknown input 
voltage from being transferred to the decode lines of the 
analog-to-digital converter. To further gain speed, 
autozeroed inverters (74, 75; 77, 78) are coupled to the output of the OR gate 
to further assure that the decoder lines are rapidly driven 
to therefore gain an extra advantage in high-speed operation 
of the converter employing the apparatus as described.
