Title: Pharmaceutical nanosuspensions for medicament administration as systems with increased saturation solubility and speed of dissolution
Inventor: MULLER RAINER H
IPC: C09K23/56
Filed: 1995-11-09
Granted: 2002-05-14
Abstract: Systems with a strongly increased saturation solubility (Cs) are obtained by preparing nanosuspensions of medicaments. The saturation solubility of medicaments with low bioavailability may thus be increased. This additional increase of the saturation solubility increases the speed of dissolution beyond what can be achieved by simply enlarging the surface of the medicament.  Extremely stable nanosuspensions are obtained by using very low surfactant and stabiliser concentrations. Surfactant-free nanosuspensions may be prepared.  Large-scale production of nanosuspensions with a very low content of micrometric particles is made possible by cavitation, with its accompanying advantages. The preparation of nanosuspensions by cavitation was thought to be impossible because the powdered medicament particles were expected to block the more or less 25 µm wide gap. Alternatively, the nanosuspensions may be prepared by shearing or impact in flow dispersion machines while respecting the above principles of optimum stabilisation or surfactant-free preparation.

Abstract: Methods and arrangements are described herein to improve the performance (measured e.g. in terms of throughput) of a RTS/CTS based distributed media access control protocol.  The medium reservation is done in a hierarchical fashion where first the shared medium is reserved for two stations called the participants. All other stations called observers stay quiet during the time reserved for the participants. In this fashion, a shared medium can be reserved for a subset of the plurality of devices. During this period called the reserved period, a master (or primary), and a slave (or secondary) station attribute can be given to the participating devices and the medium can be shared using another medium coordination algorithm which is not necessarily the same as the one used to reserve the medium for a reserved period in the first place.  After the medium is reserved, the participating devices can establish a conventional point-to-point connection within the reserved time period between participating devices for a predefined period of time. Specifically, the primary attribute can be exchanged with a secondary attribute which in effect gives the control of the shared medium during the reserved period to another station different from the one that originally was assigned the primary attribute. During the reserved time, the secondary can signal the primary station that it has data to send to the primary station and request that the primary and secondary roles or attributes to be exchanged. In the case that a role exchange takes place, the control of the medium is transferred from one station to another and data transfer in an opposite direction can take place without requiring another reservation attempt. In essence, this reduces the additional time in contention mode. Furthermore, in another aspect of the invention observing stations which are not participating in the reservation can be invited to join the initial reservation as secondary stations if this does not cause any interference to any other existing reservations. In other aspects of the invention, we define a number of additional extensions in the RTS/CTS exchange to improve the efficiency of the medium reservation by piggy-backing any reservation specific signals on data packets or defining new response frames such as Hold-to-Send (HTS) and Free-to-Send (FTS) which are used for flow control techniques in response to a congested receiving station.

Abstract: A system and method of protecting all the amplifiers in a link between wavelength routing network elements of an optical network. According to the invention, an optical control channel is added before a plurality of optical amplifier, preferably the first amplifier, in a link. To prevent improper loading of downstream links, the control channel is stripped off at the next wavelength routing network element. The power of the control channel is automatically adjusted using a fast feedback circuit to hold substantially constant the total power of the signal channels and the control channel at the input of the first amplifier following the feedback loop. In this manner, channel loading of all optical amplifiers in the link is maintained substantially constant, and the incidence of error bursts, as might otherwise result when one or more channels are added or dropped due to a network fault or reconfiguration, is substantially reduced.

Abstract: A recycled asphalt roofing material for use on sloped roofs, which provides the required elevated melt point without using prior art methods of oxidizing the asphalt prior to incorporation into the roofing material is provided. The recycled asphalt roofing material is made up of approximately 30% flux asphalt and approximately 70% reclaimed asphalt roofing material. The fibrous backing in the reclaimed material modifies the asphalt in such a way as to provide the required elevated melt point. The manufacturing process for recycled fiberglass mat-based roll and shingle roofing, in its preferred embodiment, consists of impregnating a roofing material backbone, such as a fiberglass or polyester mat with recycled asphalt material to form inner and outer layers of recycled material and then applying optional second inner and outer layers of standard asphalt coating to the inner and outer layers of the recycled material. The second coating encapsulates and seals the recycled material and thus ensures that the recycled roofing material will have the same longevity as prior art asphalt roofing materials.

Title: Method of operating the channel equalizer in a receiver for dtv signals subject to co-channel ntsc interference
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-09-18
Granted: 2002-06-04
Abstract: A DTV signal receiver includes an adaptive channel equalization filter, a comb filter (20) for suppressing artifacts of co-channel NTSC interference, and an intersymbol-interference suppression filter (26) compensating for the intersymbol interference introduced by the comb filter (20). The adaptation of the equalization filter coefficients is done so as to be insensitive to the presence or absence of the artifacts of co-channel NTSC interference. This avoids the channel equalization filter attempting to compensate for the intersymbol interference introduced by the comb filter (20), which compensation could not be fully accomplished and would make the intersymbol interference in the comb filter (20) unpredictable. The adaptation of the equalization filter coefficients is done so as not to affect the intersymbol interference introduced by the comb filter (20). Consequently, the intersymbol interference can be properly compensated for by the intersymbol-interference suppression filter (26).

Abstract: The present invention provides an IP telephony gateway. According to a first aspect of the invention, the gateway provides communications between a switched circuit network (SCN) and an IP network. The gateway can handle calls between clients on the switched circuit network and IP clients on the IP network. The gateway provides supplementary call services/features for calls to/from IP clients on the IP network, thus providing IP clients with similar features to those that are available to terminals on a PBX. The gateway is preferably a PBX which supports the supplementary services/features.      Advantageously, the gateway can also provide supplementary call services/features to calls between IP clients on the IP network. This can be achieved by routing call control signaling for IP client - IP client calls via the gateway where the services can be controlled. A further aspect of the invention provides an IP network in which IP clients have access to a range of supplementary call features/services. At least one of the supplementary features/services is provided by a gateway, such as a PBX, at an interface to the IP network. A call from an IP client is routed via the gateway to apply the supplementary feature/service.
