摘要:
A bottle cap remover can include structure for facilitating the assembly of the bottle cap remover. The structure can include a slot established within the top portion of an interior surface of the body of the bottle cap remover. The cover of the bottle cap remover, by comparison, can include an indexing guide formed within the interior surface of the cover which can cooperatively mate with a companion guide in the body of the bottle cap remover to ensure the proper alignment of the cover with the body. Moreover, a circular trench about the interior perimeter of the cover can facilitate the mating and securing of the cover to the body of the bottle cap remover.
摘要:
Polypropylene heterophasic copolymers are produced having increased impact strength through the use of controlled rheology techniques by the addition of a peroxide at conditions which increase the deactivation or half life of the peroxide. The increased half life slows down the vis-breaking process and allows better dispersion of rubber particles within the polymer. In this way, copolymers having a high melt flow can be prepared while obtaining high impact strength and lower stiffness values, without the need for additional elastomeric modifiers.

Apparatus, methods, and articles of manufacture for encoding a compressed media stream are disclosed. Example method of watermarking a digital media signal disclosed herein include copying compressed audio packets associated with an audio stream included in a transport stream of the digital media signal into respective frames of compressed audio data to be watermarked to include media identification information. Such example methods can also include determining whether a composition of the transport stream has changed during copying of the compressed audio packets into the respective frames of the compressed audio data. Such example methods can further include, if the composition of the transport stream has changed, writing the frames of the compressed audio data to an output stream corresponding to the digital media signal without applying a watermark to the frames of the compressed audio data.

An RFID reader controller and methods of controlling an RFID reader by an RFID reader controller are provided to limit or prevent the issuing of confidential information such as encryption keys, passwords, shared secrets, and the like to RFID tags if a reader is not authorized. A controller may determine the authorization status of a reader and limit its communication with the reader or instruct the reader to limit an operational aspect of the reader.
摘要:
A process for producing high impact polystyrene including feeding at least one vinyl aromatic monomer, an elastomer, and a free radical initiator to a first linear flow reactor to form a reaction mixture. Polymerizing the reaction mixture in the first linear flow reactor to a point below the point at which phase inversion occurs to produce a first polymerization mixture and feeding the first polymerization mixture from the first linear flow reactor to a second linear flow reactor. Polymerizing the reaction mixture in the second linear flow reactor to at least a phase inversion point of the mixture to produce a second polymerization mixture and feeding the second polymerization mixture from the second linear flow reactor to at least a third linear flow reactor for post-inversion polymerization of the second polymerization mixture. The product stream can have an ESCR value of at least 10% toughness retained with less than 10 wt % rubber content.

摘要:
A method for the in-situ preparation of an ionic comonomer from its chemical precursors, prepared in a solution of styrene monomer is disclosed. In one embodiment, the ionic comonomer is zirconium methacrylate, Zr(MA)4 or zirconyl methacrylate, ZrO(MA)2, or a combination thereof, and zirconium carbonate hydroxide oxide, ZrCO3(OH)2.ZrO2, and methacrylic acid, CH2═C(CH3)—COOH, are used as precursors used for its in-situ preparation.
摘要:
A transmitter upconverts a SSB data signal during a first operational mode using a RF upconverting signal having a frequency that is offset from a center frequency of a channel (ωC) by an amount that depends on the data signal's SSB bandwidth (ωM). In a second operational mode, the transmitter upconverts a tone signal having a frequency ωM using the same RF upconverting signal. The upconverted tone signal can be used as a continuous wave (CW) carrier signal having a frequency ωC. The transmitter has a single RF oscillator to output both a SSB signal centered at frequency ωC during the first mode and a carrier signal of frequency ωC during the second mode.
