Title: Connecting element for optical waveguides
Inventor: FITZGERALD ROBERT ALLEN WILLIA
IPC: G02B6/28
Filed: 1988-09-30
Abstract: Optical wave guides are interconnected with the use of two interfitting shell parts which when fitted together form a continuous tubular channel for receiving the wave guides between there. For this purpose a carrier shell part is provided with a continuous longitudinal groove of a size to accommodate a cover shell part and each part has a longitudinally extending receiving channel portion of complementary form which fit together and form a continuous receiving channel for the optical wave guides which are to be interconnected. After the wave guides are placed end to end in the longitudinally extending wave guide receiving channels defined in the carrier shell, a cover shell is engaged over the carrier shell in a manner which positions it complementary optical wave guide channel with the wave guide channel defined on the carrier shell portion. Wave guide channels are advantageously made with curved up portions at respective ends of the interfitting carrier shell and cover shell. Advantageously, the cover shell has terminal rib portions which engage over weak edges of the outer surface of the wave guide carrier shell.

Title: Filtering image data to obtain samples mapped to pixel sub-components of a display device
Inventor: PLATT JOHN C
IPC: G06K9/00
Filed: 2000-01-12
Abstract: Image data processing and image rendering methods and systems whereby images are displayed on display devices having pixels with separately controllable pixel sub-components. Image data, such as data encoded in a three-channel signal, is passed through a low-pass filter to remove frequencies higher than a selected cutoff frequency, which obtain samples from the color components of the signal that map spatially different image regions to individual pixel sub-components. It has been found that color aliasing effects can be significantly reduces at a cutoff frequency somewhat higher than the Nyquist frequency, while enhancing the spatial resolution of the image. The image data is then passed through sampling filters. A generalized set of filters includes nine filters, one for each combination of one color and one pixel sub-component. The filtering coefficients of the filters can be selected to optimize of approximate an optimization of an error metric, which represents the color and luminance errors perceived on the display device. In this manner, a desired balance between color accuracy and luminance accuracy can be obtained. The samples mapped to individual pixel sub-components are used to generate luminous intensity values for the displayed image.

Title: Process and apparatus for the production of butylacetate and isobutylacetate
Inventor: LEDERER JAROMIR
IPC: C07C67/54
Filed: 1999-03-11
Abstract: The invention relates to an apparatus for the production of butylacetate by esterification of acetic acid with butanol in the presence of a solid acidic catalyst in which distillatory separation of components runs simultaneously with esterification. Thus, acetic acid and butanol are introduced in defined amounts and in the molar ratio 1:1 to 1:10 into a system, in which the reaction and the distillatory separation proceeds in three zones. The reaction together with distillatory separation of the components with different boiling points run in the reaction zone, while only distillation takes place in lower and upper separation zones. A volatile mixture is separated in the upper separation zone, from which, after being cooled at 5 to 80° C., water and organic phases are separated, the latest being refluxed into the system. The ratio of the feed amount to the organic phase reflux amount is 1:1 to 1:20, the reflux amount representing 60 to 100% of the whole amount of the organic phase. Butylacetate is separated as a high boiling bottoms product. The invention relates also to the production of isobutylacetate by esterification of acetic acid with isobutyl alcohol in the presence of a solid acidic catalyst in which separation of components by distillation runs simultaneously with esterification.

Inventor: HYOTY HEIKKI
IPC: A61P31/12
Filed: 2000-03-17
Abstract: Live virus vaccines comprise attenuated viruses, while other vaccines comprise killed viruses or parts thereof. It has now been found that the immune response induced by oral poliovirus vaccine (OPV), which is a live vaccine, is cross-reactive with non-polio enteroviruses. OPV is therefore useful in the prevention of non-polio enterovirus diseases, especially Type 1 diabetes mellitus (IDDM). OPV is also useful in combination with killed/subunit non-polio enterovirus vaccines, whereby it prevents harmful side-effects of the killed/subunit vaccine by shifting the immune response from a harmful Th2- type response to a Th1 type response.

Title: Watertight battery compartment cover with latch actuated o-ring seal
Inventor: HERMANN ROBERT A
IPC: H01M50/213
Filed: 1999-06-04
Abstract: A cover for a battery compartment in a medical device such as an ambulatory pump that is used for infusing a medicinal fluid. The battery compartment cover includes a lever that is pivotal between an open and a closed position. The lever is connected to a plunger that applies a compressive force against an O-ring, which is trapped between a shoulder on a washer through which the plunger extends and an end of the plunger. When the lever is pivoted to its open position, the compressive force on the O-ring is released, enabling the battery compartment cover to be removed from the opening into the battery compartment. However, when the lever is pivoted to its closed position, it draws the plunger outwardly, applying a compressive force to the O-ring that causes the O-ring to expand radially outward, sealing the opening into the battery compartment against the intrusion of water or other liquids and securing the battery compartment cover in engagement with the opening.
