  • Patent number: 8912290
    Abstract: Disclosed herein is a process for preparing a linear hydroxyaryloxy-functional polydiorganosiloxanes having controlled structures. The process includes the step of reacting a linear ?,?-bisacyloxypolydiorganosiloxane with at least one bisphenolic compound, or hydroxy-functional oligomer thereof, in such a molar ratio that the phenolic groups in the bisphenolic compound or the hydroxy-functional oligomer thereof to the acyloxy groups in the ?,?-bisacyloxypolydiorganosiloxane is less than 2.0. Also disclosed are hydroxyaryloxy-functional polydiorganosiloxanes produced from the process and the polysiloxane/polyorgano block copolymers made using the hydroxyaryloxy-functional siloxanes.

  • Patent number: 8829140
    Abstract: Disclosed herein is a process for the production of a polysiloxane-polyorgano block copolymer. The process includes reacting a reaction mixture containing (a) an ester-functional polydiorganosiloxane and (b) a bisphenolic compound or a bisphenolic compound oligomer. This process has the advantage of yielding block copolymers with controlled block structures and avoiding the impurities that may be carried over from the conventional hydroxyaryloxy-terminated-polydiorganosiloxanes.

  • Patent number: 6545863
    Abstract: A compact configurable computer and mixed media workstation and enclosure designed for housing a plurality of integrated and user-provided electronic and mixed-media devices, an internal power supply, and connection cables. Said workstation and enclosure being essentially a six-sided hollow structure defined with various chambers and levels, a slide out shelf which extends from bottom of enclosure, a wing shelf which extends from opposing sides of said enclosure and provides a user work surface and a note tray and with electronics assemblies and a note taking element incorporated into said wing shelf. The top of the enclosure is characterized with a split top, where a front section is hingedly attached to the enclosure and folds forward to reveal an interior user work surface and a lower, forward work surface, and where a rear section may be configured to fold back to reveal an access door to a power and cable containment chamber. All chambers are latchable with single-throw mechanism.

  • Patent number: 6374942
    Abstract: A system and method for providing concurrent mechanical and electrical connections to a speaker system allows full rotational motion of a speaker with respect to an enclosure. The system comprises a mechanical mounting mechanism having an integrated electrical coupling mechanism configured to establish a concurrent mechanical and electrical connection between the speaker and the enclosure. The mounting system comprises cylindrical intermating members that are configured to axially and concentrically couple with one another, which allows the speaker to have a full range of rotational motion with respect to the enclosure. Thus, the system is designed so that the cylindrical intermating members of the speaker portion of the system concentrically and axially couple with the cylindrical intermating members of the enclosure portion of the system, thereby allowing concurrent electrical and mechanical coupling between the speaker and the enclosure.

  • Patent number: 5258435
    Abstract: The present invention relates to new palladium-containing polymer compositions which are characterized by a very finely disperse distribution of metallic palladium, and to the process for their preparation. Palladium-containing polymer compositions containing polymers with unsaturated groups are used inter alia as hydrogen absorbent compositions in the production of fibre optic cables for the purpose of protecting the optical fibres against hydrogen. As is well known, the diffusion of hydrogen into optical fibres has an adverse effect on the damping properties of the optical fibres.

  • Patent number: 4398207
    Abstract: An MOS integrated circuit digital-to-analog converter employing a plurality of generally parallel resistance strings. Decoding means and switching means provide an analog output from the resistance strings, this output passes through only two switches. The resistance strings may be closely fabricated on a substrate, thereby reducing the effects of processing variations. A unique layout for the converter array minimizes the effects of masking misalignments.

  • Patent number: 4092619
    Abstract: An MOS field-effect device which may be fabricated as part of an integrated circuit having the general characteristics of a lowpass filter. A source and drain region define a long channel (e.g. 500 microns or longer). The cutoff frequency of this lowpass filter which is in the audio range, is controllable by the potential applied to a gate member insulated from the channel.
