Appl. No.:

09/760353

Inventors:

Yatao Hu - Wayne PA

Assignee:

PQ Corporation - Berwyn PA

International Classification:

C12H 102

US Classification:

426422, 426423

Abstract:

An adsorbent removes certain undesirable components from beverages, such as beer, and has a low beverage soluble iron (BSI) content. These undesirable components include contaminants which cause chill haze. The adsorbent includes two components, a silica component and a polyphosphate sequestering agent component, such as sodium tripolyphosphate (STPP). The process for using the adsorbent involves first contacting a beverage with an adsorbent to adsorb at least a portion of the undesirable components then separating the adsorbent from the beverage. The adsorbent may be formed by one of two methods or a combination of both. The first method involves adding the polyphosphate sequestering agent to a reactant, such as a sodium or potassium silicate solution, prior to or during the gelation stage. A second method involves adding the polyphosphate sequestering agent to the water wash after a hydrogel is formed. The BSI of the adsorbent is substantially reduced using the first method, but the total iron content of the adsorbent appears to increase.

Abstract:

The present invention relates to an antenna array for supporting multiple beam architectures. For example, a transceiver may include an antenna array. The antenna array includes a plurality of antenna elements, where the plurality of antenna elements is configured to support at least two beam architectures in a cell site. Each beam architecture is associated with a different configuration of sectors and beamforming signals. According to one embodiment, each beam architecture is associated with a different wireless standard. According to another embodiment, each beam architecture is associated with a different carrier within one wireless standard. The antenna elements may be arranged as a circular array.

A second method involves adding the polyphosphate sequestering agent to the water wash after a hydrogel is formed. The BSI of the adsorbent is substantially reduced using the first method, but the total iron content of the adsorbent appears to increase. The second method decreases both the BSI and the total iron content of the silica gel.

International Classification:

B60P 1/00

US Classification:

414467

Abstract:

An apparatus and method for deploying a payload at a location are provided. The apparatus includes a mount adapted to be attached to a mobile unit while allowing normal operation of the mobile unit, and a deployment mechanism. The deployment mechanism supports a payload securing mode in which the deployment mechanism secures the payload to the mount and a payload deployment mode in which the deployment mechanism causes the payload to be ejected from the mount. The deployment mechanism is adapted to transition from the payload securing mode to the payload deployment mode in response to a control signal. The deployment mechanism includes a securing means adapted for securing the payload to the mount, an ejecting means adapted for ejecting the payload from the mount, and a breaking means adapted for breaking the securing means in response to a control signal, thereby causing the ejecting means to eject the payload from the mount.

Assignee:

NCR Corporation - Dayton OH

International Classification:

H01Q 124

US Classification:

343702

Abstract:

A wireless electronic module includes a folded monopole antenna having an antenna port impedance which is reactive at the RF frequency of operation and which conjugately matches the reactive impedance of the electronic circuit which connects to the antenna port. A grounded shield is interposed between the antenna and the electronic circuit to reduce RF losses at the antenna.

Abstract:

A diode detector is integrated into a microstrip patch antenna. Tuning and matching of the detector are accomplished by adjusting the geometry of the patch. Cost, power consumption, losses, and spurious responses are reduced. The antenna may be adapted to a mixer, video detector, i. f. detector, or audio detector.

International Classification:

H01Q 124

US Classification:

343702

Abstract:

An electronic price label which is suitable for use in both small EPLs having lengths of about 1. 5 to 2 inches and large size EPLs having lengths of about 3 to 4 inches. The antenna includes a folded planar conductor including a generally planar radiator portion coupled to a antenna port on a printed circuit board, a generally planar ground plane portion coupled to a ground on the printed circuit board having a width and oriented generally parallel to the radiator portion, and a dielectric layer between the radiator portion and the ground plane portion. The width of the ground plane portion is larger than the width of the radiator portion by a distance sufficient to produce an electric field which is linearly polarized in the width direction, thereby eliminating a need for shielding.
