Title: Method for improving the biocompatibility of solid surfaces
Inventor: VERHOEVEN MICHEL
IPC: A61L29/00
Filed: 1993-12-30
Abstract: ABSTRACT      A method for attaching a biomolecule having a plurality of carboxyl groups to an aminated solid surface by reacting the biomolecule with a carbodiimide to effect an activation of the carboxyl groups of the biomolecule, reacting the carbodiimide activated biomolecule with the solid surface to covalently bind the biomolecule to the aminated solid surface, and then selectively restoring carboxyl groups to the biomolecule.  The selective restoration of carboxyl groups can be carried out by mild hydrolysis and restores the functionality of the biomolecule.  The method is "selective" since the bonds between the biomolecule and the aminated solid surface remain intact.

IPC: D21C9/153
Filed: 1992-10-16
Abstract: The present invention relates to a mixing of gas into a medium.     The method and apparatus in accordance with the present invention are especially applicable in the bleaching plants of the wood process-ing industry for mixing gaseous bleaching chemicals into pulp and to bleaching process of pulp, in which the mixing method and apparatus in accordance with the present invention are applied. An excellent ap-plication is mixing ozone-containing gas into a fiber suspension flow-ing in a pipe line and an ozone bleaching process. The previously known methods and apparatuses have not been able to mix satisfactori-ly large volumes of gas, about 50 % of the total volume of the flow, into the medium flow. In the method in accordance with the present inven-tion the mixing is carried out in a strong shear force field efficiently and uniformly, whereafter the fiber network of the medium is allowed to form rapidly and in a controlled manner so that gas is not allowed to separate in the flow as bubbles, but remains in the plug flow in the fib-er network.

Next, the repeaters (100, 109, 111) establish which repeater will be the master repeater (201) based on a predetermined protocol. A  predetermined number of tasks is allocated among the repeaters (202) based on which repeater (100, 109, 111) is establish as the master repeater and each repeater configuration. Finally, message routing tables (400, 600, 700) are created based on the allocated trunking tasks, peripheral devices (106, 110, 112, 117), and communication system configuration. The message routing tables (400, 600, 700) are used in routing messages between tasks in the communication system (119).

Title: Battery feed for telephone line cards
Inventor: CONDON JOSEPH H
IPC: H04M19/00
Filed: 1994-11-21
Abstract: A battery feed circuit for supplying DC power to a telephone loop and for coupling signals to and from said loop is disclosed.  A differential amplifier having its inputs connected by way of a twisted resistive bridge to the telephone loop provides a voltage at its output which includes the signal from said telephone loop and has a DC component which is proportional to the DC current flowing in the loop.  Signals are coupled to the telephone loop by a low-inductance three-winding transformer which has two of its windings connected in series with an external power supply and the twisted bridge in order to supply current to the telephone loop.  A second differential amplifier is connected in different ways in several embodiments between the output of the first differential amplifier and the third winding of the transformer to provide an automatic flux-cancelling action in order to avoid saturation of the transformer core. Larger gain is achieved in the first differential amplifier by clamping its DC output to zero through use of an integrator circuit connected between the output and one of the inputs of the first differential amplifier.  In one of the embodiments, power is supplied to the telephone loop by a constant current source.

Abstract: A method and apparatus for a menu based system containing size and location information is disclosed. Each menu contains a list of menu items containing a command and variables that reflect the command's current appearance. This includes status information determinative of the menu item's state (enabled/disabled), its name, its associated graphic, and whether its appearance is currently valid. Each of these were initialized when the menu item was created. The invention creates a menu item from a command, where a menu item is another object data structure containing a command sequence. The menu item is added to a list of menu items, and initialized as an invalid appearance. Later when the menu its is selected from a pull down menu, the appearance state is recomputed based on the system state.
