Abstract: A method and system applies MAC transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC mechanisms are defined to support multiple mode CTS frames, and multiple mode CF-End frames sent by the AP, each in a format appropriate for the corresponding mode which also applies to a single mode as a trivial case. MAC mechanisms permit truncation of TXOP duration for releasing the unused portion of the TXOP when no further data for transmission is available. Release of unused protected TXOP is possible for both protected AP transmissions and STA transmissions.

Abstract: A cooking station for gas ranges whose burner works with super-stoichiometric combustion air premixing. The burner head arranged in a burner tray is connected with a mixing pipe via a ceramic insulating ring. Between the burner head bottom and the burner head lid with the flat topside, we have two perforated flame opening rings which are arranged concentrically with respect to the burner axis, which are resistant to heat and which are resistant to oxidizing and reducing atmospheres. The perforation of the inner flame-opening ring is so dimensioned that the flames cannot backfire. Below the burner tray there is arranged a reflector. The cooking station can be covered with a glass ceramics plate. The invention achieves stable flame performance, perfect combustion, and waste gas poor in harmful substances at nominal load and at small adjustment heat load within a vast utilization field of gases with differing Wobbe indexes as well as a start-up cooking efficiency improvement compared to known burners.

Abstract: The invention relates to apparatus for screening paper making stock, i.e. a suspension of liquid, paper making fibers and undesirable rejects, to remove a substantial portion of the rejects therefrom. In one embodiment, the apparatus comprises a cylindrical screening member (20) provided with circumferentially extending screening slots (54) in the range of from greater than approximately 0.20 mm (0.008 inch) to approximately 0.76 mm (0.030 inch) in width. Bars (56) project from the inlet face of the screen and cooperate with rotating foils (46) for creating a field of high intensity, fine scale turbulence adjacent the inlet face of the screen (20). The paper making fibers and other particles of elongated thin shapes can pass through the screening slots (54), but relatively chunky reject particles, which would pass through the larger openings of conventional paper making screens, are relected without fractionation of the paper making stock or appreciable variation in the consistencies of the feed, accepts and reject flows. The apparatus has special utility in a two-stage screening system when installed immediately ahead of the headbox of a paper machine, and also as the primary screen in a waste paper stock preparation system.

Abstract: The heretofore known transmission control system s providing automatic sequential engagement of the fluid clutches have valves directly controlled by the operator and are not readily convertible to be pilot operated. The present invention has a selector valve (31) movable between first and second positions for communicating a supply line (19) with first and second fluid clutches (11, 12) respectively. A fluid actuated valve (44) is moved to a first position communicating a third fluid clutch (13) with a drain line (18) when the fluid pressure in a fluid chamber (61) thereof drops below a preselected value and to a second position communicating the supply line (19) with the third fluid clutch (13) when the fluid pressure in the fluid chamber (61) exceeds the preselected value. A dump valve (76) drops the fluid pressure in the chamber (61) below the preselected value in response to a momentary pressure drop in the supply line (19) upon moving the selector valve (31) between the first and second positions. An orifice (81) delays filling of the fluid chamber (61) until the selected one of the first and second clutches (11, 12) is engaged. The elements of the control system are fluid actuated and are, in effect, pilot operated.

Abstract: A multiple converter system is provided for a remote user in a cable communications system. The converters at the user location are linked together by a common bus. One converter operates as a master converter transmitting a master control signal to the other converters, designated as slave converters. The slave converters are actuated only upon reception of the master control signal. The master control signal is interrupted by the master converter only when it transmits data upstream to the central office or when one of the slave converters is required to transmit data. A slave converter notifies the master converter of the need to transmit data by a slave signal on the common bus. A transmitter unit is automatically activated for transmitting data upstream upon the absence of the master signal on the bus.
