Abstract: A guideway for a magnetically levitated railway is described, having a longitudinal stator linear drive comprising at least two parallel stators. The guideway includes a plurality of supports (1) arranged along a given line and adapted to form straight and curved guideway sections and stator sections mounted on the supports (1), these sections being composed of straight stator end packs (6a, f; 7a, f) and likewise straight middle stator packs (6b-3; 7b-e) arranged therebetween, the packs in the region of the curved guideway sections being laid in the manner of polygonal trains to form outer and inner stator sections (6, 7) and being separated from one another by gaps (23, 24). The stator end packs (6a,f; 7a,f) and the middle stator packs (6b-3; 7b-e) have a predetermined tooth/groove pitch (16) with reference to a conceptual space curve (2) and different "ideal" lengths which differ from one another by fractions of a tooth/groove pitch (16). The middle stator packs (6b-3; 7b-e) are so combined with one another in at least one outer or inner stator section (6, 7), taking into account their different "ideal" lengths, that a "material" total gap between the stator end packs (6a,f; 7a,f) and the middle stator packs (6b-3; 7b-e) of this stator section (6, 7) has the smallest possible width. A  parts set and a method of making a double track guideway are also described (Fig. 2).

Abstract: A method and apparatus for generating a TCP packet connection (160) between a remote host (40) on a first network (Internet/Intranet) and a mobile station (30) on a mobile network is disclosed. The process initially involves performing a three-way handshake routine (100, 105, 110) between the remote host (40) and a gateway packet mobile switching center (55) of the mobile network to establish the validity of a TCP packet connection request. During the handshake routine transmissions (100, 105, 110) from the remote host (40) are buffered by the gateway packet mobile switching center (55). A second three-way handshake routine (145, 150, 155) is then carried out between the gateway packet mobile switching center (55) and the mobile station (30) using the buffered transmissions to complete a TCP connection (160) between the mobile station (30) and the remote host (40).

Title: Automatic control for weather radio receiver
Inventor: CHUNG KIM POR
IPC: H04B1/16
Filed: 2000-07-28
Abstract: This system is for automatically controlling a radio receiver to provide an audible broadcast of the weather alert from weather stations. It may also be incorporated in a multi-band radio for automatically switching between AM/FM broadcast and weather alert broadcast. A scanning means operates continuously to tune the weather band portion of the receiver automatically in a stepping manner to receive signals from the weather stations regardless of whether the receiver is operating in any selected AM or FM broadcasting in the multi-band radio. A combination switching comparator and switching means automatically switch the system over to the weather broadcast when a weather alert signal is detected. The switching means also automatically switches the system back to the original selected broadcast after the termination of the weather alert broadcast.

Filed: 2000-08-14
Abstract: A holder for holding a tool, having an elongated housing, including a longitudinal hole having a cross-section corresponding to the cross-section of a mounting portion of the tool bit. The housing further has at least one radial hole running from an outside surface of the connector to the longitudinal hole. The radial hole contains a substantially spherical locking means movably arranged in the radial hole. The means cooperates with a circumferential groove in the tool bit to lock the tool bit in place when the tool bit is fully inserted into the holder. A sleeve is arranged to reciprocally slide over the first connector between two end positions. The sleeve is biased towards the tool by a first biasing means, and the sleeve has a step arranged on the inside of the sleeve, which step blocks the locking means when a tool is fully inserted into the longitudinal hole. A plunger is arranged to reciprocally slide inside the longitudinal hole, being pressed by a second biasing means towards the tool. An anchoring means holds the second biasing means securely fastened to the bottom of the longitudinal hole. The holder automatically locks the tool bit in the holder after insertion and automatically ejects the tool bit after the sleeve has been released.

Title: Improved high performance muffler
Inventor: GRAVES MATTHEW
IPC: F01N1/10
Filed: 1999-01-15
Abstract: The improved high performance muffler (12) is used to attenuate the sound waves in exhaust gases from internal combustion engines and the like and has a casing (14), which includes a closed volume defined by side walls, a top wall (16), a bottom wall (18) and inlet and outlet end caps (26, 28). The casing (14) also has a defined exhaust gas-flow passageway, which extends between the end caps (26, 28), which is bounded by upper and lower walls within the casing and the side walls, and which includes inlet and outlet chambers adjacent to the inlet and outlet end caps, respectively. Two spaced apart, gas-flow channels. A gas-flow director assembly (56), disposed between the side walls and the upper and lower walls, defines two spaced apart gas-flow channels. The gas-flow channels have a uniform, smooth cross section, and their lengths are substantially equal. The gas-flow director assembly (56) divides the exhaust gases flowing into the gas inlet chamber into two substantially unrestricted and equivolume gas streams, and also defines an intermediate chamber, which communicates with the gas-flow channels, intermediate their ends, so as to permit the exhaust gases flowing in the channels to expand and mix for sound attenuation. Perforations in the upper and lower walls permit sound waves in the exhaust gases to be attenuated in sound absorption materials (91, 102) disposed in the closed volume of the casing about the gas-flow passageway.

Title: Process for production of organic disulfides
Inventor: SULZER GERALD M
IPC: C07C319/00
Filed: 1999-02-12
Abstract: An aqueous solution of basic mercaptide salt and water-soluble peroxide are mixed together in a reaction zone and maintained under reaction conditions effective to produce a vapor phase comprising organic disulfide, and concurrently vapor phase is recovered from the reaction zone. The process is highly efficient and enables production of organic disulfides in high yield and purity. Not only is the process very easy and simple to carry out, but in addition the process (i) eliminates the need for forming an organic phase of liquid organic disulfide product and conducting a separation between such product and the total aqueous phase used in the reaction, (ii) enables efficient control of a highly exothermic reaction, and (iii) minimizes alkanesulfonic acid salt formation during the reaction.

Abstract: A method of transmitting time division multiplexed data from a satellite terminal to a satellite wherein the satellite terminal receives a command indicating to transmit data during a frame comprising a plurality of timeslots in accordance with a timeslot reordering scheme. The timeslot reordering scheme is selected to spread data from respective satellite terminals to different timeslots throughout the frames. A processor monitors the use of channels by the satellite terminals, stores bandwidth requests using queues, allocates channels in accordance with bandwidth requests and a bandwidth allocation algorithm, and transmits the channel allocations in a frame. Timeslots not allocated to any of the satellite terminals are contention channels. The number of contention channels changes dynamically, depending on demand for the plurality of channels by the satellite terminals. Queues are provided for each channel for storing high and low priority rate requests and high and low priority volume requests. The bandwidth allocation algorithm determines the preemption of the queues, and allocation priorities.
