Abstract: Methods and apparatus for processing Physical layer Protocol Data Unit (PPDU) based on Basic Service Set (BSS) identification information in a High Efficiency WLAN (HEW) are described. An embodiment is a method for processing a PPDU by a station (STA) in a wireless local area network. The method may include determining whether the PPDU is transmitted from a different Basic Service Set (BSS) from a BSS to which the STA belongs or a same BSS as the BSS to which the STA belongs; and processing the PPDU using a first type of Clear Channel Assessment (CCA) threshold when the PPDU is determined to be transmitted from the different BSS, wherein the first type of CCA threshold is greater than a second type of CCA threshold which is used when the PPDU is determined to be transmitted from the same BSS.

Abstract: A control apparatus, for starting and operating a high-temperature electric furnace (F) for melting refractory materials, includes a three-phase power supply (Phase A, Phase B and Phase C) for supplying energy to three electrodes (E1, E2 and E3) of the furnace. Included in the connections between the power supply and the furnace electrodes are three input transformers (T1, T2 and T3) one for each phase. The primary of each transformer includes a tap-changer section. Connected between the power supply and the tap-changer are two current paths connected in parallel. The first current path is non-inductive. It includes at least one silicon controlled rectifier (SCR-A, SCR-B and SCR-C). This path is used after steady state conditions have developed. The second current path is highly inductive. The inductance is controlled by a continuously variable transformer (BT-A, BT-B and BT-C) commonly known as a Variac. This path is used during start- up. The combination, in series, of the tap-changer and Variac controlled inductance in a second path which is used during start-up, provides a vernier control of the voltage, and, hence, the current, applied to the furnace electrodes (E1, E2 and E3) during start-up, with the inductance providing protection against sudden current surges which would otherwise tend to blow fuses and open circuit breakers (CB1, CB2 and CB3).

Abstract: An apparatus for freezing confection material includes a plurality of separate mold strips which are indexed in a closely spaced single file over several longitudinally spaced, transversely extending rows of nozzles. Coolant is forced upwardly from the nozzles in single vertical jets which impinge perpendicularly against the mold strips midway between adjacent mold cups. The mold cups are arranged with their wide side faces extending in their direction of travel, and the single jets of coolant impinge upon wall portions of the mold strips which extend transversely between such opposing wide side faces. The heat exchanger for refrigerating the coolant includes a vertically super-imposed array of heat exchanger tubes that is located directly under the mold cups so that the coolant will drip from the mold cups onto the heat exchanger tubes. The coolant then cascades from upper to lower heat exchanger tubes and is refrigerated by the time it trickles into a collection housing situated below the heat exchanger. Mechanical seals are formed between the adjacent mold strips by intermeshing end walls of the mold strips; the seals enable the coolant to be continuously sprayed without concern that the coolant may be injected upwardly between the strips to contaminate the confection material.

Abstract: In this method and means the reciprocating grinding shoe is briefly lifted at certain time intervals from the surface of the profiled piece to be ground in such a way that an air cushion is built up between the profiled surface and the abrasive paper of the grinding shoe during lifting of the latter from the profiled surface, which air cushion is subsequently displaced abruptly and energetically out of the space between the workpiece and the grinding shoe during the renewed return movement of the grinding shoe in the direction of the profiled piece. The apparatus according to the invention has a lifting device, which is operatively connected to the reciprocating grinding shoe, and also a compressed-air source which is provided with feed lines and/or discharge nozzles for feeding compressed air between the surface of the profiled piece to be ground and the bottom surface of the grinding shoe accommodating the abrasive paper. <IMAGE>

Abstract: The invention relates to inflatable gas bags for providing a protective cushioning effect for occupants of a vehicle in the event of an accident. More particularly, the invention is directed to an igniter for an inflator for pyrotechnically inflating such a protective gas bag. 
     In one embodiment, the igniter includes two igniter segments comprising tubes (10, 11) having outlet ports (14), and filled with ignition material. The tubes are connected in tandem by an interconnector (12). A fast burning fuse (16) passes through the interconnector (12) and directly contacts the ignition material in one tube (11), whilst contacting a delay disc (15) of propellant in the other tube (10). In operation, when the igniter is operatively assembled within an inflator containing propellant, and when the igniter is activated, the ignition material in tube (10) is initially ignited, igniting the adjacent inflator propellant, and after a delay determined by the burn rate of the delay disc (15), the ignition material in the tube (11) is also ignited, igniting the inflator propellant adjacent the latter tube. 
     Thus, the igniter causes the propellant in the inflator to ignite in a progressive manner so as to inflate the bag slowly atthe onset but more rapidly later as inflation progresses. The overall inflation time is very rapid, but the slow onset of bag deployment starts gentle movement against the vehicle's occupant, and thus reduces the possibility of injury as compared wth a more sudden movement by rapid inflation from the outset.

Abstract: A device for the angular adjustment of a camshaft of a combustion engine according to speed and load conditions and to the angular position of the camshaft with respect to a driving wheel being controlled by an adjustable mechanism. The technical problem is the angular adjustment of the single or multiple camshafts with respect to the crankshaft according to speed and load conditions. Tooth pulses, or counting pulses, corresponding to the angular position of the crankshaft (2) and reference pulses corresponding to a particular angular reference position (singular tooth) are generated by a transducer, or pulse generator, controlled by the toothed ring associated with the crankshaft and the ignition circuit (13). An address counter (10) is reset by the reference pulses and incremented by the tooth pulses so that the output of the counter provides digital address signals corresponding to the actual angular position of the crankshaft (2). The output signals of the address counter and digital signals corresponding to load conditions are input to a correction processor with memory, (20) the output of which provides a camshaft adjustment signal. During pre-set engine operational periods, a buffer memory ( 21), controlled by the tooth-pulse time base signal, stores an adjustment signal used as a camshaft correcting variable, which is then delayed under asynchronous clocking and fed into an electromechanical control device (FIG. 3) which effects a rotary-then-linear displacement of a control member (31) and subsequently an angular corresponding displacement of the camshaft(s) to the correcting variable.
