Patent CA-2185962-A1 (CA)
Inventor: CARBERRY JOEL P
IPC: G02B6/28
Filed: 1996-09-19
Abstract: To make an overclad fiber optic coupler, the bare regions of a plurality of optical fibers are positioned within a glass capillary tube.  The midregion of the tube is then collapsed and stretched to cause coupling characteristics, the fibers. To obtain desirable coupling characteristics, the fibers must be situated in the glass tube bore in side-by-side fashion such that the cross-sectional configuration of the fibers constitutes a given geometrical array.  So ensure that the fibers are properly positioned within the glass tube, they are fed to that tube from a plurality of guide tubes, the ends of which are retained adjacent to the end of the glass tube in side-by-side fashion in the given geometrical array.

Title: Cleaning tool head with overlapping and offset fluid spray patterns
Inventor: GRAVE DALE L
IPC: A47L11/34
Filed: 1996-04-04
Abstract: A cleaning device (16) includes a head (30) to enhance surface cleaning and drying. The head (30) includes a shell (32) to form an enclosed chamber (53) with the surface (18). A partition (80) divides the chamber (53) into an intake compartment (82) and an evacuation compartment (84). A row of nozzles is mounted to the shell to spray liquid cleaning solution into the intake compartment. Air enters the receiving sector through slots near the nozzles and between a forward portion of the shell and the floor, and is drawn beyond the partition into the evacuation compartment by a vacuum source. Each of the nozzles generates a sheet-like, fan-shaped spray patterns. The nozzles are arranged to form adjacent spray patterns that overlap one another longitudinally (lengthwise of the elongate shell) but are separated from one another to avoid interference between adjacent spray patterns. In one particularly advantageous arrangement, the nozzles are angularly offset from the lengthwise direction to from parallel spray patterns that define air passages between them. The shell, particularly along and adjacent the surface being cleaned, is configured to promote air flow into the intake compartment while resisting air passage into the evacuation compartment.

Patent CA-2231801-A1 (CA)
Inventor: SANDBERG HELENA
IPC: A61K47/48
Filed: 1996-09-27
Abstract: The present invention relates to a process for improving the in vivo function of a polypeptide by shielding exposed targets of said polypeptide, by immobilizing the polypeptide by interaction with a group-specific adsorbent carrying ligands manufactured by organic-chemical synthesis, activating the biocompatible polymer, conjugating the thus activated biocompatible polymer to the immobilized polypeptide, and thereafter eluting the conjugate from the adsorbent. The present invention further relates to conjugates of a polypeptide and a biocompatible polymer obtainable by the present process, and use of said conjugates as medicaments. Specifically, the polypeptide is factor VIII, the von Willebrand factor or factor IX. The invention is particularly advantageous for conjugates where the polypeptide is factor VIII with a high specific activity using monomethoxy polyalkyleneoxide (mPEG) as the biocompatible polymer.

Title: Simplifying decoding of codewords in a wireless communication system
Inventor: RAITH ALEX KRISTER
IPC: H04W74/02
Filed: 1996-10-18
Abstract: A method and apparatus determine whether reserved bits of a field are assigned a function; if not, the bits may be used for enhanced functions such as equalization and synchronization. An indication whether reserved bits have been assigned a function may be sent on a broadcast channel by a usage-information element. Decoding of the coded superframe phase/packet channel feedback (CSFP/PCF) field also is improved by reducing the number of possible codewords in the CSFP/PCF field, based on the superframe phase (SFP) information. The length of a codeword to be decoded may be reduced based on an indication in the usage-information element whether a CSFP/PCF field bit is reserved. Generally, the block code of any channel coded word, not necessarily packet data, may be effectively reduced based on knowledge of some information in the coded word.
