Patent EP-0283099-A3 (EP)
Title: A method of producing figured knitted fabric lengths on a flat knitting machine
IPC: D04B1/10
Filed: 1988-03-17
Abstract: With certain advanced knitting methods it is possible to 
produce arbitrarily figured knitted fabrics, but when using 
a flat knitting machine the figuring has so far been limited 
to the inclusion of transverse, throughgoing stripes made 
of one or more rows of stitches. With the invention advan­
tage is taken by the fact that the needles (4) of such a 
machine are switchable between an operative and a non-operative 
condition, as it is hereby possible to knit in one or more 
rows of stitches (20-24) of a figure producing yarn along 
only a partial width of the fabric, from one edge thereof, 
while thereafter, optionally after addition of an additional 
throughgoing stripe of one or more rows (28) of stitches, 
it is possible to effect a complementary knitting in of 
stitches and stitch rows (30) from the opposite edge of 
the fabric, whereby the earlier introduced wryness of the 
fabric will be relieved or compensated for. The result is 
a flat knitted fabric that may show stripe figures terminating 
at places on the very fabric surface spaced from one of the 
edges thereof, and/or stripes (28) stretching partially in 
a curved manner.

Patent EP-0275149-A3 (EP)
IPC: G02B6/122
Filed: 1988-01-07
Abstract: A method of improving device performance of optical devices formed 
in optical substrates is disclosed. The method requires that the optical substrate 
material be pre-annealed to form a surface layer with a known congruent 
composition before diffusing the waveguide material into the substrate. By pre-­
annealing all material, the diffusion rate of the waveguide material will remain 
relatively constant, regardless of the particular boule. The pre-annealing can be 
accomplished either by pre-equilibrating the lithium niobate in a vapor-phase 
equilibration crucible containing pre-reacted lithium niobate cullet with the desired 
composition, or pre-equilibrating the lithium niobate to the  Li ₂ O -rich phase 
boundary in a two-phase ( LiNbO ₃,  Li₃NbO ₄) powder bed.
Patent EP-0285403-A3 (EP)
IPC: A61M5/145
Filed: 1988-03-30
Abstract: A portable infusion pump assembly utilizing continuous drive 
propulsion means (8) to effect automatic and incremental displacement of a 
plunger (5) within a disposable syringe (3) so as to deliver accurately 
repeatable volumes of fluid from the syringe (3) over a predetermined 
period of time.  
     Intermittent drive of the continuous drive propulsion means (8) is 
effected. Comparison of desired delivery rate with actual delivery rate is 
made by use of angular displacement signals received from a shaft encoder 
(10) attached to the shaft of the continuous propulsion means (8).  
     This method of control also allows indirect measurement of fluid 
pressure in the syringe (3) without the need for a pressure sensor to be 
located in direct contact with the fluid being delivered.

Patent EP-0357051-A3 (EP)
IPC: H03K17/968
Filed: 1989-08-30
Abstract: A contactless switch comprising a moveable body 
assembly (18) including a plunger (5) and a lens carrier (16) 
received in a casing (1) in an axially slidable manner between a 
light emitting element (9) and a light receiving element (10) 
which are also disposed along and on the axial line of 
the casing (1). Thus, the radial dimension of the switch 
can be reduced, and a compact design is made possible. 
Additionally, the actuating stroke of the moveable body 
assembly (18) can be made large without increasing the 
dimensions of the switch. In particular, since a 
switch output can be produced from a signal processing 
circuit when the amount of the light received by the 
light receiving element (10) has reached a certain 
predetermined level, the point of activation of the 
switch can be accurately defined by adjusting a 
reference level for the level of the light received by 
the light receiving element (10), and this adjustment can be 
easily carried out.

Title: Extended drug delivery of small, water-soluble molecules
IPC: A61K9/28
Filed: 1990-08-31
Abstract: A polymeric device releasing biologically active, water-soluble materials having a molecular weight of less than 1000 in a controlled, continuous and linear manner over an extended period of time. Insoluble polymer matrixes can be defined in any shape, size and drug content. When applied to medical use, biocompatible polymers are used so that the device is implantable. The device is made by modifying prior art devices based on diffusion of fluid into a polymeric matrix containing dispersed biologically active molecules to yield a polymer device which can be placed in a fluid environment, so that fluid is absorbed by the device and the water soluble molecules diffuse into the fluid environment, leaving behind pores and channels, where the rate of diffusion is limited by an impermeable coating over a portion of the polymeric matrix and/or by adjusting the drug loading to produce the number and size of pores and channels to the surface of the polymeric matrix yielding the desired release rate of the biologically active molecules. The device is characterized by several distinguishing features: a mechanism usually associated with macromolecular release which is applicable to small, water soluble molecules and controlled, long term linear release of large drug quantities.

Title: Data redundancy and recovery protection
IPC: G06F11/14
Filed: 1990-11-02
Abstract: A method for detecting the presence of a replacement disk in a fault tolerant, intelligent mass storage disk array subsystem having a microprocessor based controller in a personal computer system and rebuilding the replacement disk independent of the computer system processor. The method calls for the microprocessor controller to run a disk array check at system powerup or at specified intervals at which will detect the existence of a replacement drive. The microprocessor then builds a series of disk drive commands which attempt to read every sector on the replacement disk. The read commands will return a null data read, indicating that the sector must be restored. The microprocessor controller converts the replacement read commands for all sectors on the replacement disk to write-restore commands. The microprocessor executes the write commands and restores the data to the replacement drive.
