Title: Hand-tied hair weft
Inventor: SMITH DAFINA
IPC: A41G5/00
Filed: 2020-09-04
Abstract: Apparatus and associated methods relate to a hand-tied hair weft having at least two hair bundles fixed to three or more thread-like filaments that provide a cortex, where each two adjacent hair bundles are separated by one or more knots formed by the three or more thread-like filaments. In an illustrative example, the two adjacent hair bundles may be separated by, for example, at least two knots. The knots may include overhand knots. By introducing one or one or more knots, the width of the hand-tied hair weft may be customized without the weft shedding or unraveling.

Abstract: Systems, methods and instrumentalities are disclosed to transmission scheduling. A station (STA) in its own basic service set (BSS) receiving a transmission frame from an overlapping BSS (OBSS). The STA may decode preamble of the received transmission frame. The STA may determine, for example, using the decoded preamble that OBSS information and transmit scheme associated with the OBSS. On a condition that the transmit scheme associated with the OBSS is orthogonal frequency divisional multiple access (OFDMA), the STA in its own BSS may indicate to its access point (AP) that one or more channels or sub-channels that are available or not available for transmission. On a condition that the transmit scheme determined from the preamble of the transmission frame is orthogonal frequency divisional multiplexing (OFDM), the STA may determine that a channel is not available for transmission. The STA may set the channel to busy or idle.

Abstract: Die Erfindung geht aus von einem Verfahren zur optischen Darstellung von Informationen, bei dem in einem Fluoreszenzkörper Umgebungslicht eingefangen und an ausgewählten Stellen wieder ausgekoppelt wird, und zwar dadurch, daß durch Anlegen einer elektrischen Spannung reflektierende Schichten in optischen Kontakt mit dem Fluoreszenzkörper gebracht werden. Erfindungsgemäß wird vorgeschlagen, diese Reflexionsschichten dadurch zu erzeugen, daß man aus einer Flüssigkeit einen Niederschlag abscheidet. Dieser Neiderschlag wird vorzugsweise durch eine elektrochemische Reaktion aus einem Elektrolyten gewonnen und ist normalerweise entweder ein Metall wie Silber oder eine (organische) elektrochrome Schicht. Das vorgeschlagene Verfahren ermöglicht eine Lichtausbeute von über 90°0, gestattet eine zeitlich unbegrenzte, sofort löschbare Speicherung der eingegebenen Information und gibt keine konstruktiven Probleme auf.

Abstract: An improved multi-station machine 10 is disclosed for assembling ring-type closures from generally cylindrical paperboard cylinders and generally circular paperboard discs. The machine employs a rotatable dial plate 50, carrying eight mandrels 54 and an improved ring clamping system (102,104), which dial plate is incrementally rotated by an automatic indexer assembly 24 relative to the various operating stations which consist of a ring feed station 200, a discfeed station 300, and adhesive dispensing station 500, a curling station 650, a grooving station 700 and a closure ejecting station 800. Means are provided for controlling the operation of the various stations so that they operate in substantial synchronism with one another and with the rotatable dial plate 50. The improved disc feed station 300 automatically feeds the lowermost disc from a stack of discs to a position lover a ring on the dial plate and simultaneously forms a i peripheral skirt on the disc and positions it in an open end of the ring. The adhesive dispensing station 500 employs a pair of tube pumps 562 to dispense adhesive and lubricant on partially assembled ring-type closures. The grooving station 700 automatically forms a peripheral groove and a corresponding radially inwardly extending rib in the cylindrical wall of an assembled ring-type closure. The closure ejecting station 800 provides vacuum means 814 for withdrawing a completed closure 896 from a mandrel 54 on the dial plate 50 and pressurized air means 888 for assisting in the automatic removal ofthe closure from the mandrel and for automatically propelling the'thus removed closure from the machine. The ring feed station 200 provides means for preventing the introduction of rings onto the dial plate 50 in response to an indication of insufficient discs at the disc feed station 300. Control means are provided for manually indexing the dial plate 50 as well as prevention of disc feed, and adhesive and lubricant dispensing if an appropriate ring is not present on the dial plate 50, as well as control means for preventing ring feed if sufficient discs are not available at the disc feed station 300. Various other control features are disclosed for the prevention of operator injury, material waste and machine jamming.

Abstract: A power source arrangement for electric discharge machining in which a power source and a switching element are connected in parallel to an electrode and a work and the switching element is driven by a pulse signal of a predetermined period from an oscillator OSC1 to perform electric discharge machining of the work. There is provided a pulse signal generator OSC2 to OSC4 and OR for generating such a pulse signal that the ratio of its OFF period to its ON period gradually increases with the lapse of time and a detector SD for detecting the occurrence of an arc or short in the spark gap between the electrode and the work. Upon detection of arcing or shorting in the spark gap by the detector SD, the pulse signal generator OSC2 to OSC4 and OR is activated so that the pulse signal of the predetermined period from the oscillator OSC1 to be applied to the switching element is gated at gate AND by the output pulse signal from the pulse signal generator OSC2 to OSC4 and OR until the arc or short is removed.

Abstract: Bei der üblichen Transformationskodierung von Bildern entsteht eine Vergrösserung der Wertebereiche der dabei erzeugten Koeffizienten bei der Durchführung der einzelnen Rechenschritte. Dadurch enthalten diese Koeffizienten eine erhebliche Redundanz, so dass die Wirksamkeit der Datenreduktion bei der anschliessenden Quantisierung vermindert wird. Erfindungsgemäss werden die auf der Grundtransformation von jeweils zwei Werten aufbauenden Rechenschritte so durchgeführt, dass sich als Ergebnis jedes Rechenschritts nur die ursprüngliche Wortlänge ergißt, indem bei jedem Rechenschritt ein Teil des Wertebereichs der Ergebnisse in einem anderen Bereich abgebildet wird. Es wiid ein Beispiel für die technische Durchführung einer solchen Abbildung auf modifizierte Koeffizienten und die Rücktransformation dieser modifizierten Koeffizienten beschrieben. Dabei müssen zweckmässig spezielle Quantisierungskennlinien angewendet werden, die noch zusätzliche Vorteile bringen.

Abstract: Vorliegende Erfindung behandelt ein Verfahren zur Herstellung von 2-Phenylethylchlorsilanen. Als Ausgangsprodukte werden Hydrogenchlorsilane und Styrol eingesetzt, die im Rahmen der an sich bekannten Additionsreaktion miteinander umgesetzt werden. Erfindungsgemäß findet diese Umsetzung in Gegenwart von Benzothiazol statt. Das Benzothiazol wird mindestens in der Menge eingesetzt, in der der Platinkatalysator ebenfalls eingesetzt wird. Das bevorzugte Molverhältnis von Platinkatalysator zu Benzothiazol liegt zwischen 1:2 und 1:50. Die Umsetzung läßt sich mit hohen Ausbeuten an dem 2-Isomeren, das praktisch frei von dem 1-Isomeren ist, bei Temperaturen bis zu etwa 90°C durchführen. Dabei kann ein Überdruck bis zu 6 bar durchaus toleriert werden, ohne daß die Ausbeuten an dem gewünschten Endprodukt merklich abfallen.
