Patent EP-0167323-A3 (EP)
IPC: H01L31/065
Filed: 1985-06-18
Abstract: An amorphous semiconductor photovoltaic device hav­
ing improved long term efficiency stability. The improved 
stability is achieved by grading the band gap energy of a 
portion of the photo-responsive layer of the device. The 
widest band gap energy portion of the photo-responsive 
layer is disposed nearest the light-incident surface of the 
device. The band gap gradation may be smooth or stepped, 
and may be accomplished by varying the composition of the 
source materials during deposition of the photo-responsive 
layer.

Title: Vibratory grinding of silicon carbide
IPC: B02C17/20
Filed: 1986-03-19
Abstract: A method for reducing the particle size of an initial silicon carbinde powder to a milled powder having an average particle size of below 1 micron but greaterthan an average of about 0.2 2 micron, without grinding media contamination. The method comprises milling the larger particles in a vibratory mill in the presence of sintered silicon carbide media comprising silicon carbide pellets having both curved and flat surfaces and a maximum dimension of from about 0.5 to 5 centimetres. The grinding occurs in the presence of a fluid, preferably a liquid, for a sufficient time and at a sufficient vibrational energy to obtain said milled powder having such smaller average particle size. At least 90% of the pellets in the silicon carbide media have a specific gravity (density) greater than 3.05 g/cm<sup>3</sup>.The invention includes the unique media, which may be used for various grinding operations, and includes unique milled powders. One of the unique powders has particles which have an average length to width ratio of greater than 2.5. Another of the unique powders is black silicon carbide containing from 200 to 2,000 parts per million of aluminium in solid solution.

Abstract: Recombinant transforming growth factor-β1 (TGF-β1) is 
expressed to high levels in Chinese hamster ovary (CHO) cells 
using dihydrofolate reductase (dhfr) gene amplification. The 
expression plasmid was derived from the pSV2 vectors and 
contained, in tandem, the simian TGF-β1 and mouse dhfr cDNAs. 
Transcription of both cDNAs was controlled by the SV40 early 
promoter. Stepwise selection of transfected CHO cells in 
increasing concentrations of methotrexate yielded cell lines 
expressing amplified TGF-β1 nucleic acid sequences. The 
expression plasmid DNA was amplified greater than 35-fold in 
one of the methotrexate selected transfectants. The major 
proteins secreted by these cells consisted of latent TGF-β1 
and TGF-β1 precursor polypeptides as judged by immunoblots 
using site-specific anti-peptide antibodies derived from 
various regions of the TGF-β1 precursor. Levels of 
recombinant TGF-β1 protein secreted by these cells approached 
30 ug/24 hour/10⁷ cells.

Patent EP-0282140-A3 (EP)
IPC: H05K13/04
Filed: 1988-03-08
Abstract: A gripping device for an apparatus for placing electronic 
and/or electrical components with terminal pins on a substrate 
comprises a pair of grippers (9 and 10) which are movable 
relative to one another by fluid-pressure operated means to close 
and open the jaws (12 and 13) of the grippers. The force for 
driving the pins of a component into the respective holes in the 
substrate is applied to the component through abutment means 
which are self-adjustable to accommodate differences in the 
heights of the components so that the gripper jaws can be brought 
to a constant level at the pick-up position each time and can be 
arranged to grip the component over areas which extend to the 
bottom of the body of the component to facilitate accurate 
positioning of the terminal pins in relation to the respective 
holes in the substrate when mounting the component. The abutment 
means comprise a spring-loaded, vertically disposed rod (18) 
which is movable vertically relative to the gripper jaws 
(12 and 13) and which abuts the upper side of the body of the 
component (16) as the gripping device is lowered to the pick-up 
position. As the gripper jaws close on the component a friction 
element (26) is moved to engage the side of the rod (18) to lock 
the rod in abutment with the component so that the rod can 
subsequently transmit the necessary force to the component to 
insert the terminal pins into the holes in the substrate. The 
friction element (26) is actuated by a piston (32) through a 
bell-crank lever (28), the piston being controlled by the valve 
means (not shown) which control the actuation of the grippers.

Title: Yarn feeder device for feeding yarns having elastic characteristics for a knitting machine, in particular for a hosiery knitting machines
IPC: D04B15/58
Filed: 1988-10-04
Abstract: In order to feed two or more yarns having elastic 
properties in a hosiery knitting machine, so as to 
constantly secure the same feeding conditions for all 
yarns, and precisely the same speed and tension, a common 
feeder roll (10) is provided, with which the yarns are in 
tangential contact on different peripheral positions, 
pressed against the roll by an equal number of pressure 
rolls (11) rolling around the periphery of the feeder roll (10). 
The revolution speed of the roll, and therefore the yarn 
feed speed, can be varied by driving the feeder roll (10) by 
means of a rotary disk (24), the flat surface of which is in 
revolutionary engagement with a drive wheel (35) which is 
axially-shiftable, but integral in rotation with the 
feeder roll (10), in such a way that, by varying the position 
of the drivewheel (35) in the radial direction of the disk (24), a 
different revolution speed of the drive wheel (35), and 
consequently of the feeder roll (10), is obtained.
