Title: Improving transmission opportunity truncation
Inventor: TIAN QINGJIANG
IPC: H04W74/08
Filed: 2017-08-24
Granted: 2021-12-23
Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for improving transmission opportunity (TxOP) truncation in wireless communication. In some implementations, a transmit opportunity (TxOP) period truncation or whether to update a network allocation vector (NAV) timing based on a message that includes transmitter and receiver information (such as a transmitter address (TA) and a receiver address (RA)) may be determined. For example, a station may receive a contention-free end (CF-End) frame and determine a TxOP period truncation based on comparing a TA and an RA included in the CF-End frame with a TA and an RA included in an earlier received message (e.g., an RTS). Such information may be compared to other TAs or RAs associated with NAV timing values and the NAV timing may be set, reset, updated, or canceled based on the comparison.

Title: Shaft with two bearings
Inventor: LENK ERICH DR-ING
IPC: B65H54/46
Filed: 1987-05-23
Granted: 1988-12-08
Abstract: Rotating shafts have critical speeds, and cannot therefore be operated within the range of these critical speeds. As a result of harmonic vibration occurrences, several critical speeds can follow one another in very close succession, thereby adversely affecting hypercritical operation. To make hypercritical operation possible within wide speed ranges, the shaft is weakened in the longitudinal area in which the reversal point of its second critical bending vibration lies. This weakening can be effected particularly by equipping the shaft with a flexible intermediate section (3). <IMAGE>

Patent DE-4109991-C1 (DE)
IPC: B01D53/70
Filed: 1991-03-27
Granted: 1992-06-25
Abstract: The invention relates to a process for reducing the polluting content of the flue gas from thermal processes, especially in the aluminium remelting process. To this end, finely divided metals and/or their oxides, hydroxides and/or oxihydroxides with an affinity for halogens are introduced into the heating flame but not in such quantities as would be necessary for the complete avoidance of the formation of dioxin and/or furane. To absorb the remaining pollutants, especially dioxins and furanes, the flue gas leaving the combustion chamber is sprayed with an incombustible oil-wateremulsion, preferably after the flue gas has passed through a preliminary washing process.

Abstract: A heat exchanger has two heating zones which are assigned to the driver's and passenger's sides, consist of finned-tube blocks and open at the end into an upper and lower collecting space. Two return lines lead away from the upper collecting space, and the feed line is connected to a duct which extends on the side with the collecting space and whose two outlets are arranged in the region of predetermined heating tubes. Even given periodically recurring slight flows of heat-carrying medium, a pleasant temperature stratification is achieved in the heat exchanger when the duct connected to the feed line is arranged in the lower collecting space and when the duct located in the upper, centrally split collecting space is subdivided centrally by a partition into two duct halves from which a return line leads away respectively. Inlet and outlet are respectively situated approximately at right angles to one another.

Title: Attachment for an electrically operated hand mixer
Inventor: REBORDOSA ANTONIO
IPC: A47J43/06
Filed: 1994-04-25
Granted: 1995-04-06
Abstract: Attachment (1) with a container (2) closeable by a cover (9) for an electrically operated hand mixer (10) has at least two drive shafts, a first (90) and a second (77) which are suitable for releasable connection to various working tools (76), such as whisks or dough hooks. One of the drive shafts (90) can, by placing the hand mixer (10) onto the cover (9) of the attachment (1), be connected in a rotationally fixed manner to an output shaft (16) passing upwardly through the cover (9). The output shaft (16) is connected to a knife (21, 22) capable of being driven inside the container (2) for the purpose of comminuting foodstuffs. The rotationally fixed connection is effected by engagement of a first toothing (71) formed in the first drive shaft (90) and a second toothing (70), corresponding thereto, formed on the output shaft (16). The output shaft (16) is displaceable, according to the invention, against the force of a spring (67) axially towards the cover (9) to such an extent that, during the placing-on process of the hand mixer (10), the latter comes to bear on the cover (9), even when there is still no engagement between first (71) and second (70) toothing. As a result, the hand mixer (10) can be simply placed on the attachment (1) without at the same time having to pay attention to whether the second toothing (70) formed on the output shaft (16) engages in the first toothing (71), formed on the hand mixer (10), of the drive shaft (90). <IMAGE>
