Inventor: KUMAR DEVENDRA
IPC: A62D3/00
Filed: 2003-05-07
Abstract: Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for various plasma processes and treatments. In one embodiment, a plasma is ignited by subjecting a gas in a multi-mode processing cavity to electromagnetic radiation having a frequency between about 1 MHz and about 333 GHz in the presence of a plasma catalyst, which may be passive or active. A passive plasma catalyst may include, for example, any object capable of inducing a plasma by deforming a local electric field. An active plasma catalyst can include any particle or high energy wave packet capable of transferring a sufficient amount of energy to a gaseous atom or molecule to remove at least one electron from the gaseous atom or molecule, in the presence of electromagnetic radiation.

Abstract: A wireless communication network (100) includes roving subscriber-stations (114) and base stations (110) receiving a broadcast programs from a content server. A subscriber-station evaluates (618, 620) whether a desired program is available from a subject base station. According to this evaluation, the subscriber-station takes steps to (1) receive the desired program on a shared channel for reception by multiple subscriber-stations (816), or (2) initiate (804, 720) base station delivery (724) of the desired program to the subscriber-station on an individual channel. Responsive to a message from a subject subscriber-station identifying a desired program, a base station either (1) continues (819) transmitting the desired program upon a shared channel, (2) starts (816) transmitting the desired program on a shared channel, or (3) sends the subject subscriber-station a channel assignment message and commences transmission (722) of the desired program on the assigned individual channel.

Abstract: A one-piece, integrally formed tie apparatus is provided in which a line engaging portion releasably engages line (14) and a vine holding portion releasably loosely holds vines (19). The vine holding portion includes an elongate flexible arm (18) integrally depending from the line engaging portion and elastically deformable to define a loop. A spherical locking head is formed at a remote end of the flexible arm (18) and a complementary locking part (40) engages the spherical head to close the loop completely to surround the vines (19). The complementary locking part (40) is also responsive to application of predetermined amount of force to the flexible arm substantially in at least one direction, within the range of directions (75), to permit pulling of the spherical head out of its engagement with locking recesses (such as 56), in the pair of sidewall extensions (50, 52) and pulling of the spherical head between the sidewalls (46, 48). This opens the closed till loop and permits removal of the vines (19) whilst leaving the tie apparatus on the line (14).

Abstract: Monovalent ions, especially chloride, fluoride and thallium, are efficiently removed from ZnSO4 electrolyte by electrodialysis using alternating monovalent anion permselective membranes and cation exchange membranes or monovalent cation permselective membranes. Electrodialysis is carried out under turbulent flow conditions, at up to 60 DEG C, a differential membrane pressure of less than 150 kPa, a current density of 10 to 500 A/m<2>, and a pH of less than 5.5. Where both chloride and fluoride are removed a pH of 3.5 to 5.5 is maintained. Deposition of manganese and zinc on the electrodes is minimized by at least one of a number of means including arranging the membranes such that the end membranes are monovalent anion permselective; selecting a large electrode rinse flow; adding a small amount of soluble antimony and/or cobalt to the rinse flow; and using a cathode made of a material that promotes hydrogen evolution over zinc deposition. The electrode compartments are preferably rinsed with a 0.1 to 1.0 M Na2SO4 solution at pH 0 to 4.

Abstract: The invention relates to a rotary drum of relatively large dimensions, the casing of which is mounted rotatably by ball races (3, 4) on in each case a roller pair (7) of a roller station (5, 6). To this end, the rotary drum casing (2) bears only two ball races (3, 4) which are mounted in a rotationally fixed manner and are mounted on two roller stations (5, 6), at least one of which simultaneously forms the rotary drive device for the rotary drum in the form of a friction-wheel drive. The result is thus a combination of features, by means of which the rotary drum is mounted in a statically determined manner and at the same time can be reliably driven in an extremely simple manner.

Abstract: Pulse frequency modulation is used to control brakes and clutches 10 which are operated by fluid pressure actuators 22 controlled by electrically actuated solenoid valves 28. Short pulse periods for all duty cycles are generated by feedback from the solenoid valve 28 or from the actuator 22. In one circuit an electrical control 30 triggers a flip-flop 38 which starts solenoid current. Solenoid movement results in back-emf and its effects on the solenoid flux field or current is detected and used as a feedback signal to reset the flip-flop 38 to thereby turn off the current as soon as the valve 28 is operated. In another circuit, a computer control 30' emits a command for a certain pulse period. Actuator pressure or position is monitored to produce a feedback signal to the computer. If the signal is not received, the pulse period is increased for the next pulse command so that a sufficient pulse period will be found. If the magnitude of the actuator response exceeds a threshold, the pulse period is decreased for the next pulse command. Pulse width modulation may also be improved by the same technique for minimizing the pulse period at the lowest duty cycles and yet assuring actuation. <IMAGE>
