Abstract: A child resistant package having a panel that obstructs removal of the articles being held within the package. When the package is fully opened or fully closed, the panel offers resistance to the removal of the articles contained therein. Only when the panel is in an aligned position do holes in the panel properly align so that the articles within the package can be removed. Each article is sandwiched between a top base portion and a bottom base portion of the package such that the panel can slide in-between the base portions when the package is opened or closed.
Abstract: The oral antigens and adjuvants of the present invention are produced in transgenic plants and then administered through the consumption of the transgenic plant. DNA sequences both natural and synthetic encoding for the expression of immunogenic agents which are capable of causing an immune response in animals when fed in edible plants, plant tissues, or derived plant materials are constructed, and plants transformed for stable or transient expression in plant cells. The present invention provides the first known functional method for immunizing animals via transgenic plants, where the plants express bacterial antigens that act as both immunogen and adjuvants when the transgenic plant material expressing the antigens is fed to animals.

Abstract: A system for fitting pins into a connector, wherein the pins are formed by portions including an end portion of a continuous wire, which portions are arranged one after another and linked together by and separable at frangible regions. The continuous wire is fed to a first unit which advances the wire and guides the end portion of the wire in a rectilinear direction of advance toward a second unit. The second unit is mounted on a rotary shaft perpendicular to this rectilinear direction and rotated so that the end portion of the continuous wire is introduced into the second unit by the first unit and then the second unit is further rotated to cause separation of the end portion from the continuous wire by bending. The second unit then inserts the separated portion into the connector.
Abstract: A system, method and apparatus for establishing a secure wireless radio communications link between two devices that minimizes the exposure of sensitive information to third party interception is disclosed. The secure link is established by first establishing an infrared link between the two devices for the exchange of sensitive information, such as encryption information. Subsequent communications would then have the benefit of encryption protection, establishing the secure wireless radio communications link.
Abstract: The invention provides a method for recovering low-boiling acids from a concentrated solution of the calcium salt of the acid by treating the concentrated solution of calcium salts of the low-boiling acids with a high molecular weight tertiary amine and carbon dioxide.
Abstract: The invention concerns a method for producing a paper web. According to the method a stock is produced from the fibrous raw material and the stock is formed to a web which is dried on a paper machine. According to the invention the stock is formed from a mechanical pulp prepared from wood material of the Populus family and from bleached chemical spruce pulp, whereby the amount of the mechanical pulp is 20 to 70 weight-% and the amount of the bleached chemical softwood pulp is 80 to 30 weight-% of the dry matter of the stock. It is preferred to use an aspen pulp, over 70% of the fiber fractions of which comprise fiber fractions +100, +200 and −200, and the proportion of the −200 fraction is 45% or less. A coated fine paper can be produced from the paper web whose properties are better than those of a traditional fine paper having the corresponding bulk and grammage, on the same capacity level the paper produced by the invention will give a yield gain of up to more than 20%.

Abstract: A cyclodextrin composition of substantially pure, sulfated-cyclodextrin derivatives particularly suitable as chiral resolving agents for enantioseparation by electrophoresis. The cyclodextrin composition preferably have an isomeric purity of at least 80 mole %. Non-sulfato substituents for the substantially pure cyclodextrin derivatives are hydrogen, C1-C12 alkyl groups, C2-C8 hydroxyalkyl groups, C1-C12 alkylnitryl groups, C2-C12 acyl groups, aryl groups, carbamate groups, thiocarbamate groups or combinations thereof.
Abstract: An electrical connector for interconnecting a portable radio and accessory devices. The connector attached to the accessory device includes a slot for initially engaging a tab on the portable radio, which provides proper alignment between the portable radio and the connector, while the connector is rotated toward the portable radio. Maintaining alignment ensures proper mating between the electrical contacts of the portable radio and the electrical contacts of the connector, and further ensures that a quarter turn latching device of the connector is properly received by a receiving member on the portable radio. The user then rotates the quarter turn latching device to urge the contacts against each other and secure the connector in place. Because the electrical connector includes a two-point attachment mechanism to the portable radio, rotation of the connector relative to the portable radio is prevented.
Abstract: A pressurized-fluid-operated actuator has two piston surfaces for providing increased output force. The actuator includes a hollow piston that is divided into two inner chambers by a stationary inner dividing wall that is rigidly connected with a cylinder end wall. The piston has an outer diameter that is smaller than the inner diameter of the cylinder, and the piston carries three axially spaced sealing rings that define two axially-spaced annular chambers between the piston and the cylinder. Each of the annular chambers is in fluid communication with a respective port provided in the cylinder wall. Introduction of pressurized fluid into one port causes the fluid pressure to act on a single piston surface to retract the piston and rod, and introduction of pressurized fluid into the other port causes the fluid pressure to act on two axially-spaced piston surfaces to provide an increased output force without increasing the diameter of the cylinder and piston and without increasing the pressure of the fluid.

Abstract: A technique for enhancing the modifiability and reuse of telecommunications software systems is described. The problem domain is first partitioned into tasks that are assigned to distinct software program modules. In one embodiment, each of the software modules have multiple output ports. Each output port provides a mechanism to link the software module to a specific version of a different program module. The multiple output ports are used to selectively link the module to one of several versions of a different program module. The linking is performed as early as system design time or as late as run-time, or at any intermediate time between the two. The use of output ports makes software modules less dependent on each other and also simplifies the “hot-swapping” or dynamic replacement of one module by another at run-time. In an alternative embodiment, each of the software modules has a unitary output port where each output port comprises an array of linking records.
Abstract: An integrated radio telecommunications network which integrates an ANSI-41 circuit switched network and a General Packet Radio Service (GPRS) packet data network to support a mobile station which operates in both the ANSI-41 network and the GPRS network. An interworking function interfaces a mobile switching center (MSC) in the ANSI-41 network with a serving GPRS switching node (SGSN) in the GPRS network by mapping circuit switched signaling utilized by the MSC into GPRS packet switched signaling utilized by the SGSN, and mapping GPRS packet switched signaling into circuit switched signaling. An interworking GPRS base station controller interfaces the SGSN with a GPRS/ANSI-136 base station which supports both ANSI-136 operations and GPRS operations. The interworking GPRS base station controller adapts the traffic signaling format utilized by the SGSN into an air interface traffic signaling format utilized by the GPRS/ANSI-136 base station.
Abstract: A process for treating phenol with a strong acid ion exchange resin to reduce the level of methylbenzofuran is provided. The process is capable of being carried out at elevated temperatures for extended periods, such that cooling of the phenol from distillation temperatures prior to the resin treatment is not required. The process can reduce or eliminate the substantial costs associated with conventional processes that require cooling and re-heating the phenol.
Abstract: A system for detecting an underwater object includes an optical signal generator operable to generate and transmit an optical signal into the water. The system also includes an absorption cell operable to receive the optical signal reflected from the water and absorb an unshifted frequency component of the reflected optical signal. The system further includes a detector operable to receive a shifted frequency component of the optical signal from the absorption cell and detect the object using the shifted frequency component of the optical signal. Displacement of the water by the object causes an absence of a portion of the shifted frequency component of the optical signal.

Abstract: A process for preparing a protein-polysaccharide conjugate includes reacting a protein with a polysaccharide to produce a mixture including a protein-polysaccharide conjugate and free protein. At least one unreacted reagent or low molecular weight component is removed from this mixture, without removing all of the free protein, to provide a purified mixture that contains the protein-polysaccharide conjugate and free protein. This purified mixture can be used as a conjugate vaccine, immunogen, or immunological reagent. Keeping the free protein in the purified mixture with the conjugate saves time and money in the conjugate production process. In another aspect of the invention, the purified mixture of the protein-polysaccharide conjugate and free protein is reacted with a hapten to produce a conjugate mixture including a hapten-protein conjugate and a hapten-protein-polysaccharide conjugate.
