Title: Process for producing pure and dense amorphous synthetic silica particles
IPC: C01B33/18
Filed: 1989-07-14
Abstract: A method of producing pure and dense amorphous fused 
synthetic silica. Silica of desired purity is wet pelletized or 
agglomerated to form particles having an average particle size 
of between about 5 to 2500 microns. These particles are 
calcined to volatilize impurities and increase density to at least 
about 0.9 g/cm³. Calcined particles are classified by size or 
reduced in size if desired or needed by grinding in such a way 
that the purity of the product is maintained.

Title: Particle measuring method and apparatus
IPC: G01N15/02
Filed: 1989-09-20
Abstract: Disclosed is a particle measurement method and 
apparatus for measuring particle properties in which a 
laser beam (5) is projected into a detection region (6) 
in a medium containing particles to be measured, and a 
photoelectric detector (11) having a predetermined 
dynamic range is used to detect the laser light scattered 
by the particles in the medium to produce signals which 
are evaluated to measure the particle properties. The 
polarization (S, P) of the laser beam and the intensity 
of the scattered light are regulated using filter means 
(10, 59) in accordance with the range of particle sizes 
measured so that the intensity of the scattered light is 
within the dynamic range of the photoelectric detector 
(11). This arrangement makes it possible to expand the 
range of particle sizes with an improved resolving power 
in particle measurement without multi-valued ranges.

Title: Vacuum deposition system
IPC: C23C14/56
Filed: 1989-10-11
Abstract: A system (10) for the vacuum processing of 
substrates such as semiconductor wafers which includes a 
central handling chamber (14), a number of separately 
pumped and randomly accessed process chambers (16-19), 
and dual load lock chambers (22) which communicate with 
the central handling chamber. This configuration 
permits one batch of substrates to be subjected to load 
lock evacuation while a second batch, having been 
previously evacuated, is transferred one at a time to 
selected process chambers. Substrate transfer from the 
load locks to the central handling chamber is by means 
of elevators (42) and by means of a handling assembly 
(24) which undergoes O and Z motion only, with final 
transfer from the central handling chamber to the 
process chambers being accomplished by pivoting platen 
assemblies (66).

Title: Paper roll towel dispenser
IPC: A47K10/34
Filed: 1989-04-20
Abstract: A web transfer mechanism in a paper roll towel dispenser of the type having a primary roll (12) and a reserve roll (14) of paper toweling comprises a cradle (16) for supporting the primary roll (12) that is counterbalanced by an element (32) for tucking the leading end of the reserve roll (14) into the nip between feed rollers (24,26). As the primary roll (12) becomes depleted, the counterbalancing force of the roll decreases, causing the tucking element (32) to gradually approach the leading end of the reserve roll (14) until the element (32) finally engages the end and introduces it into the nip. In a preferred embodiment, the device includes a damper mechanism (36,38) to prevent premature introduction of the leading end caused by the tendency of the primary roll (12) to rise above the cradle (16) by a sudden pull on the toweling.

Abstract: A new method is provided to impart a hydrophilic lubricious coating onto articles such as medical devices. A device, for example a catheter, is first contacted with a polyisocyanate solution, to provide coupling, then contacted with a poly(carboxylic acid) solution to give a coating, and is then finally oven dried. These coatings have lubricity that only becomes manifest upon exposure to water or body fluids, and moreover, are also long lasting and have good abrasion resistance. This combination of properties is not available from other currently used or proposed coatings such as Teflon.

Title: Percutaneous devices with flanges of variable stiffness
IPC: A61M39/02
Filed: 1990-02-07
Abstract: A percutaneous implant device (20) has a main 
body portion (30) and a flange (56) extending outwardly 
to a free edge (60) thereof from the main body portion. 
The flange (56) can have a thickness that decreases 
toward the free edge and the stiffness of the flange (56) 
decreases away from portions of the flange nearest the 
main body portion (30) to portions of the flange nearest 
the free edge (60). This stiffness characteristic can 
be accomplished by a flange density that decreases 
outwardly or by the flange having a porosity which 
increases toward the free edge. The thickness and 
density of the flange can decrease, while the porosity 
increases, toward the free edge. The thickness and 
thread count of a textile flange can decrease toward the 
free edge, or the thickness and packing density of a 
fibrous flange can decrease toward the free edge.

Patent EP-0396343-A3 (EP)
Title: Wire dot printer
IPC: B41J2/30
Filed: 1990-04-27
Abstract: A wire dot printer has a thermistor that detects the 
temperature of a print head (1) and a counter (5) that starts 
counting when the detection temperature exceeds an alarm 
temperature. The printer can be controlled by switching 
over between normal-printing and reduced-character-printing 
in which a reduced number of print wires is used.  
     When the detection temperature exceeds the alarm 
temperature, the printer will first stop and then control 
the print head (1) in such a way as to reduce the temperature. 
Once the temperature drops back down below the alarm 
temperature, the printer will perform reduced-character-printing 
for a definite period of time based on the length 
of time from when the temperature exceeded the alarm 
temperature to when the temperature dropped back down below 
the alarm temperature.  
     By increasing the length of time in which reduced-character-printing 
is carried out, the amount of heat given 
off by the print head (1) decreases. Furthermore, by basing the 
time over which reduced-character-printing is performed on 
the length of time that the alarm temperature was exceeded, 
it is possible to set the reduced-character-printing time to 
an appropriate length such that the print head (1) does not 
overheat and throughout is not excessively impaired.

Title: Measurement method to determine the rupture elongation of a sample under stress in computer controlled stress testing
IPC: G01N3/08
Filed: 1991-08-09
Abstract: The invention relates to a measuring method to determine elongation after fracture on a tensile testpiece in a computer controlled tensile test. To meet the requirements of the tensile test to DIN EN 10002/1, the measuring grid known from DIN EN 10002/1 is applied to the tensile testpiece. The measuring grid is scanned with a line sensing camera. In the tensile test the elongation of the testpiece is determined when the tensile force has exceeded its maximum and drops to zero. That place for which the computer with the CCD camera detects the greatest distance between adjacent grid lines is utilized to calculate the elongation after fracture to DIN EN 10002/1.

Patent EP-0573307-A3 (EP)
IPC: G06F11/00
Filed: 1993-06-04
Abstract: A host computer including a posted write cache for a disk drive system where the posted write cache includes battery backup to protect against potential loss of data in case of a power failure, and also including means for performing a method for determining if live data is present in the posted write cache upon power-up. The posted write cache is further mirrored and parity-checked to assure data validity. Performance increase is achieved since during normal operation data is written to the much faster cache and a completion indication is returned, and the data is flushed to the slower disk drive system at a more opportune time. Batteries provide power to the posted write cache in the event of a power failure. Upon subsequent power-up, a cache signature previously written in the posted write cache indicates that live data still resides in the posted write cache. If the cache signature is not present and the batteries are not fully discharged, a normal power up condition exists. If the cache signature is not present and the batteries are fully discharged, then the user is warned of possible data loss. A configuration identification code assures a proper correspondence between the posted write cache board and the disk drive system. A mirror test executed to verify data validity. Temporary and permanent error conditions are monitored so that posted write operations are only enabled when error-free operation is assured. <IMAGE>
