Title: Passivated and stabilized porous supports and methods for the preparation and use of same
Inventor: GIROT PIERRE
IPC: G01N30/88
Filed: 1993-06-18
Granted: 2001-02-06
Abstract: This invention relates generally to modified porous solid supports and processes for the preparation and use of same. In particular, passivated porous mineral oxide, polymeric, or polymer-coated mineral oxide supports are disclosed which are characterized by a reversible high sorptive capacity substantially unaccompanied by non-specific adsorption of or interaction with biomolecules. Passivation is achieved by use of a passivation mixture comprising a main monomer, a passivating monomer and a crosslinking agent, which mixture upon polymerization results in the substantial elimination of the undesirable non-specific interaction with biomolecules.

Abstract: A thermal nose protector for use in subfreezing climates, e.g. by an alpine skier with ski goggles. The thermal nose protector consists of a flexible shield sheet material sized to conformingly fit over the skier's nose and having at least a first and a second layer. The first layer is made from a soft, thermally insulating material for direct engagement with the skin of the skier's nose. The second layer is of the multiple-hook type for separable gripping engagement with a corresponding portion of the foam-like, peripheral, interior strip of the ski goggles. The flexible shield sheet extends beyond the tip of the skier's nose whereby a substantially open air pocket is defined by the nose-covering the shield sheet beneath the skier's nose and ahead of the skier's mouth, wherein an air breathing channel is formed coextensively of the open air pocket for promoting air breathing from the nose of the skier. The air breathing channel extends generally transversely of the direction of displacement of the skier whereby the nose of the skier is thermally protected from incoming wind.

Abstract: A control mechanism is provided for operating a control valve in a water conditioning system. The control mechanism includes a timing mechanism for regulating the regeneration cycle and service cycle of the water conditioning system and a control valve positioning mechanism for operating the control valve of the water conditioning system. The control valve positioning mechanism and the timing mechanism are driven by a drive mechanism. The drive mechanism includes a timing drive gear which is in driving engagement with the timing mechanism and a control valve drive gear which is in driving engagement with the control valve positioning mechanism. A clutch selectively couples the control valve drive gear to the timing drive gear to provide selective conjoint rotation of the control valve drive gear with the timing drive gear. The clutch includes a coupling member having a first end wrapped around a stem of the timing drive gear and a second end wrapped around the stem of the control valve drive gear. When the timing drive gear is rotated the coupling member couples the control valve drive gear to the timing drive gear for conjoint rotation. However, when the clutch is selectively gripped by a pivotable cam arm, the control valve drive gear is uncoupled from the timing drive gear such that the timing drive gear rotates without any corresponding rotation of the control valve drive gear.

Abstract: An apparatus and method for correcting printing characteristics of a full-line printhead, and producing a high-printing quality printhead at high manufacturing yield, a corrected printhead by this apparatus, and a printer employing this printhead. According to this method, an image is printed on a printing medium by using double pulses obtained based on fluctuation of resistance of each printing unit of a printhead, and a reference OD value is determined from an OD value histogram of the printed image. A preheating pulse width is selected, based on OD values of n printed images obtained by changing the preheating pulse width n times and the reference OD value, such that an OD value on each printing element is equal or close to the reference OD value. For example, assuming that the reference value is 0.43, a preheating pulse width on printing element No. 3 is 0.875 µ sec.

Abstract: A fire extinguisher for closed spaces comprises a pressure container provided with a release valve. The pressure container contains an extinguishant liquid in connection with the release valve. The pressure container contains at the side opposite from the extinguishant liquid in relation to the release valve a pressurized driving gas which at activation of the release valve discharges the extinguishant liquid from the pressure container at a high pressure. At least one nozzle is connected with the release valve for atomizing the extinguishant liquid supplied to the nozzle from the release valve. Thereby the nozzle creates a liquid fog filling the closed space and extinguishing a fire therein substantially by displacing the oxygen in the space.
