Title: Endothelial cell growth factor
IPC: C07K16/00
Filed: 1989-12-15
Abstract: A process for the purification of homogeneous plate-derived endothelial cell growth factor (PD-ECGF) from a platelet lysate comprises subjecting the lysate to cation exchange chromatography on CM-Sephadex, pooling and subjecting the resulting active fractions to anion exchange chromatography on QAE-Sephadex, pooling and subjecting the resulting active fractions to ammonium sulfate precipitation, pooling and subjecting the resulting active fractions to anion exchange chromatography on DEAE-Sepharose, pooling and subjecting the resulting active fractions to high-performance hydroxylapatite column chromatography, pooling and subjecting the resulting active fractions to high performance hydrophobic column chromatography on an alkyl-Superose resin, and recovering said homogeneous platelet-derived endothelial cell growth factor. The process, which can be carried out in five steps, allows for purification of PD-ECGF that results in about 1,250,000-fold purification at a yield of about 14%.

Title: Soldering device with at least one bow-shaped electrode
IPC: B23K3/04
Filed: 1990-01-04
Abstract: In a soldering device with at least one bow-shaped electrode (B1), which can be heated by means of electrical resistance heating, its rectangular working surface (A1) is intended to be capable of being positioned exactly parallel on the solder point which is located, for example, on a printed-circuit board. This is made possible by means of a pivotable suspension of the bow-shaped electrode (B1), the dislocated rotation axis (Da1) of this pivotable suspension having to run in the plane of the working surface (A1), centrally and at right angles to the longer side of the working surface (A1). In consequence, a more secure contact of the parts to be soldered to one another and to the working surface of the soldering bracket (B1) is ensured. In the case of soldering devices having two or four soldering brackets, each individual one of these soldering brackets is pivotably suspended individually.

Title: Micro-displacement detector device, piezo-actuator provided with the micro-displacement detector device and scanning probe microscope provided with the piezo-actuator
IPC: G01B7/00
Filed: 1990-04-06
Abstract: A scanning tunnel microscope includes a piezo-actuator 
(16) movable in a direction Z perpendicular 
to the surface of a sample (12) and provided with a 
scanning probe (14) projected downward from the bottom 
thereof. The scanning probe (14) is moved in the 
direction Z by the piezo-actuator (16). The piezo-actuator 
(16) includes a position measuring probe (22) 
projected therefrom, parallel to the surface of the 
sample (12), from the lower end of one side thereof. 
A reference sample (26) having concaves formed on a 
surface thereof at predetermined intervals is fixed to 
the piezo-actuator (16). When the scanning probe (14) 
is moved in the direction Z, the position measuring 
probe (22) is moved along the reference sample (26), 
so that tunnel current having a waveform which reproduces 
the shape of the concaved surface of the reference 
sample (26) is detected. Thus, the moving distance 
of the scanning probe (14) can be obtained from the 
waveform of tunnel current detected.

Title: Scannable interface to non-scannable microprocessor.
Inventor: RAHMAN MIZANUR MOHAMMED
IPC: G06F11/267
Filed: 1994-06-20
Abstract: A diagnostic system for diagnosing states of circuit elements is described, wherein scannable circuits can be scanned without disturbing the state of unscannable circuits of violating protocols of busses on which unscannable devices are attached. One unscannable device is a standardized microprocessor. A processor interface circuit is coupled between the microprocessor and scannable processor circuits, via a processor bus, to insulate the scannable processor circuits from the unscannable microprocessor. The processor interface circuit is also scannable, including memory elements which affect the bus, by preventing a scan when the bus is in use. A scan is prevented through the use of a maintenance request signal from a scan controller to the processor interface circuit, and one or more maintenance approval signals from the processor interface circuit to the scan controller. <IMAGE>

Patent EP-0797077-A3 (EP)
Inventor: TAZARTES DANIEL A
IPC: G01C21/16
Filed: 1997-03-10
Abstract: The invention is a method for compensating for coning in a strapdown inertial navigation system
which utilizes groups of five successive incremental angles of rotation of a body-fixed coordinate system
as measured by orthogonally-mounted gyros at regular measurement intervals, each group of five
measurements being obtained during a group interval equal to five measurement intervals. The coning-compensated
angular displacement of the body-fixed coordinate system about a fixed axis in space
during a p'th group interval is obtained by summing the five measured incremental angles and a coning
compensation term. The coning compensation term consists of the sum of: (1) one-half the cross-product
of a first and a second vector sum, the second vector sum being the sum of the five incremental
angles of rotation in a group and the first vector sum being the sum of the second vector sum over p
groups; and (2) the weighted sum of three vector cross-products, the multiplier and the multiplicand of
each vector cross-product being a weighted sum of five measured incremental angles. The coning-compensated
angular displacement can be summed over p to obtain an accurate estimate of the vector
angle of rotation over a plurality of group intervals.
