Abstract: A twist-lock connector assembly for securing an engaged electrical plug to an electrical socket (or outlet) that includes a rotatable cylindrical sleeve disposed enclosing an electrical plug. In use, the electrical plug is inserted into the socket and the cylindrical sleeve is rotated about a 1/4 turn. This causes the inner disposed nubs of the sleeve to lockingly engage the outer disposed threads of the upstanding cylindrical wall of the cover plate. This prevents the electrical plug from being accidentally pulled loose from the socket. One aspect of the twist-lock connector assembly provides securing engagement of an electrical plug to a female socket portion of an extension cord. The female socket is enclosed by a retractable sleeve provided with engaging nubs adapted to lockingly engage the external threads of the rotatable sleeve of the electrical plug. Another aspect of the twist-lock connector assembly provides rapid twist-locking connection between a female connector of an extension cord and the male connector end of a whip end of handle portion of an outdoor power tool.

Abstract: L'invention concerne un pignon (112) présentant une diminution du pas à la corde à l'état neuf ou sorti d'usine. Ce pas Ps'à la corde du pignon a été intentionnellement diminué par rapport au pas de chaîne normal Pc (ou pas à la corde maximum théorique) selon un niveau sélectionné désigné "diminution ajoutée du pas à la chaîne". Cette diminution ajoutée vient en complément à la diminution existante due aux tolérances de fabrication. L'incorporation de cette diminution ajoutée du pas à la corde facilite la prolongation de l'intervalle temporel d'engrènement pour un rouleau de chaîne associé. Ce pignon (112) est conçu pour présenter un pas à la corde diminué par rapport à un pas à la corde théorique maximum (ou pas du maillon de chaîne) de 0,2 % à 1 % du pas à la corde théorique maximum du pignon.

Abstract: A anti-copy programme signal is provided. Copies of the anti-copy video pulses made on a video recorder experience reduced quality and interference in playback making them unpleasant to watch. The uncopied signal can be viewed without any material effect on picture quality. The signal comprises a pulse (28) added to each line (6) of the signal throughout both the visible picture region and throughout the vertical blanking region (12), as well as a first modulated wave-form (34) added to the vertical synchronisation pulses (16) of the signal and a second modulated wave-form (36) added to several lines (6) of the picture signal before the vertical blanking section (12). The presence of all three of these features together has been found to be provide a surprising accumulative effectiveness in causing interference in the reproduction of the modified video signal during playback of the copied video signal, that is greater than the effectiveness provided by the different features taken separately.

Title: System and method for communicating digital information using time-and-frequency-bounded base functions
Inventor: BOASSON ERIK
IPC: H04J4/00
Filed: 2003-12-19
Granted: 2012-10-30
Abstract: Systems and methods for efficiently conveying one or more broadband communication channels over a transmission medium. Communication is effected by transforming an incoming digital bit stream into a Time-and-Frequency-Bounded (TFB) information stream that includes a plurality of TFB packets. This transformation is accomplished through the use of a plurality of TFB basis functions. The TFB information stream is then transmitted over the transmission medium. More particularly, digital bit streams carried on one or more incoming channels are in the form of binary "on" and "off" bits. These digital bits are converted into a plurality of TFB waveform components which together comprise a TFB packet. The conversion process maps each of respective incoming digital bits to a corresponding one of a group of TFB functions, such that a first group of n bits is mapped to a first TFB function, a second group is mapped to a second TFB function, and so on, until the Nth TFB function is reached, whereupon the process cycles back to the first TFB function. In any case, the value or status of a group of bits is represented by a corresponding weighing factor for the corresponding TFB function. When weighed, each respective TFB function specifies the transmission of a corresponding TFB waveform component. Each waveform component is substantially confined within a range of values in both the frequency and time domains.

Granted: 2012-01-17
Abstract: Tissue products are described that have been topically treated with a chemical additive, such as a softener. The softener may be, for instance, a polysiloxane. The polysiloxane is topically applied to a tissue sheet, such as a single ply sheet, so as to form a Z-directional gradient in the sheet.  Particular, most of the polysiloxane remains on the surface of the tissue product as opposed to migrating to the center of the sheet. In this manner, tissue sheets are formed with improved softness at lower levels of polysiloxane and without the need for applying any surfactants to the sheet. A  system for applying chemical additives to tissue sheets is also described. The system includes a chemical additive applicator, such as a meltblown die that emits the chemical additive through a plurality of orifices. In one embodiment, the system includes a device for periodically cleaning the orifices during application of the chemical additive. The cleaning device may be, for instance, a brush that traverses across the die head when desired.
