Title: System and method for administering two liquids
Inventor: BARAK SWI
IPC: A61M5/168
Filed: 1998-02-24
Abstract: A flow set (10) which enables the sequential administration of two liquids from a pair of containers (12, 14) to a patient. The flow set has a pair of valve assemblies (16, 18) each in communication with a container. Each valve assembly has three ports communicating through a communication chamber; an inlet port being sealed with a first one-way valve allowing flow of liquid through it only into the chamber, an outlet port being sealed with a second one-way valve allowing flow of liquid through it only out of the chamber, and a pump communication port. A pair of inlet tubing segments (20, 22) each connect a container to the inlet port of a valve assembly. A connecting tubing segment (30) connects the pump communicating ports of the two valve assemblies. An outlet tubing segment (24, 26) connects to the outlet port of each valve assembly for delivery of the liquid to the patient. A pump (60) is connected to the connecting tubing segment. By reversing the pumping direction of the pump, liquid may be sequentially drawn from one container or the other.

Title: Method of adaptive control of the presence of a copy protection signal
Inventor: RYAN JOHN O
IPC: H04N5/913
Filed: 1997-07-16
Abstract: A method and apparatus for adaptively controlling the presence of copy protection signals in a video signal depends upon the scene content of the video signal during an upper portion of a display of the video signal. Thus, in the upper portion of the scenes, wherein picture information would be noticeably altered by a hooking process the copy protection process is deactivated or effectively reduced to eliminate or reduce the hooking or tearing effects. The adaptive control of the copy protection improves the playability performance of copy protected video signals on a very small minority of television receivers which display a small hooking or tearing characteristic in the upper portion of the display of the copy protected video signal.

The process comprises the steps of preparing a powder essentially consisting of iron and optionally at least one alloying element selected from the group consisting of chromium, manganese, copper, nickel, vanadium, niobium, boron, silicon, molybdenum, tungsten, decarburizing the powder in an atmosphere containing at least H2 and H2O gases, measuring the concentration of at least one of the carbon oxides (alternatively gases) formed during the decarburisation process, or measuring the oxygen potential in at least 2 points located at a predetermined distance from each other in the longitudinal direction of the furnace, adjusting the content of the H2O-gas in the decarburising atmosphere with the aid of the measurement. Another alternative concerns measuring the carbon oxides in combination with measuring the oxygen potential.
Patent CA-2265134-A1 (CA)
Inventor: KATO OSAMU
IPC: H04J13/18
Filed: 1999-03-10
Abstract: During asymmetric communications using only the uplink, frame configuration section 109 transmits a signal made up of only pilot signals and transmission power control bits assembled into frames. The transmission power control method is the same as that for normal communications. In this case, since signals transmitted on the downlink are only pilot signals and transmission power control bits, it is possible to reduce the transmission rate considerably and transmit signals with its transmission power reduced by transmission signal amplitude control section 111. In this case, a long hierarchic orthogonal type spreading code is set as the spreading code used by spreader 110.

IPC: B05B3/10
Filed: 1998-12-28
Abstract: By provision of paint cartridges (35) of different colors which are detachably mounted on a coating system (21), the paint can be changed from one color to another in a multi-color coating operation without necessitating to discharge residues of a previous color. The paint cartridge (35) of each color is replaceably mounted on a housing (22). Each cartridge (35) is provided with a paint valve (46) which functions to communicate and shut off a paint supply passage (39A) in a feed tube (39). In addition, a thinner valve (54) which serves to communicate and shut off a thinner passage (48) on the housing is provided either on the side of the housing (22) or on the side of the cartridge (35). These arrangements make it possible to cope with multiple color changes on one coating system (21). Since both of the paint valve (46) and thinner valve (54) are opened and closed by spray-on and spray-off command signals, respectively, the paint spray can be turned on and off immediately in response to these command signals.
Patent CA-2282610-A1 (CA)
Inventor: BULTHUIS HINDRIK FREERK
IPC: G02B6/12
Filed: 1999-09-16
Abstract: The invention pertains to an optical waveguide structure comprising at least one optical main waveguide and at least one power tap for tapping of signal power carried in the guided mode of the optical main waveguide, wherein for tapping the optical main waveguide gradually widens over a length LtaPer to a width WtaPer and then gradually narrows to a finite width, thereby forming a tapered waveguide, and the power tap branches from the tapered waveguide. The tapered form of the waveguide allows only a fraction of the guided mode to be coupled into the power tap; hence the loss resulting from the power tap is kept to a minimum. Further, tapping is virtually wavelength-independent and the manufacturing tolerance is good.

Title: Preparation of high activity catalysts; the catalysts and their use
Inventor: MAULDIN CHARLES H
IPC: C10G2/00
Filed: 1998-04-17
Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide conversion reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a polyol is employed to impregnate and disperse a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel, or in a preferred embodiment both a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support, e.g., titania. The rhenium, when present only in small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the polyol. Higher catalyst activities with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required to both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly, as little as about 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the polyol.
