Abstract: A petroleum wax-free chewing gum with enhanced flavor release, particularly chewing gums with increased perception of breath freshening, are disclosed. Enhanced flavor release is obtained with wax-free chewing gums where the Solubility Parameter, defined: as   of at least 5 % of the flavoring agent is at least 0.5 units greater than, or less than, the average weighted Solubility Parameter of the gum base used to formulate the wax-free chewing gums of our invention.

Title: Synthesis of 1,4,7-triazacyclononane derivatives
Inventor: MADISON STEPHEN ALAN
IPC: C07D255/02
Filed: 1993-06-16
Granted: 1998-09-22
Abstract: An improved process is described for obtaining triazacyclononanes (1), especially 1,4,7-trimethyl-1,4,7-triazacyclononane. The first step involves reacting diethylenetriamine (DET) with a sulfonylation agent to form a sulfonamidated DET, in an aqueous medium with an inorganic base. In a second step, but preferably within the same reactor vessel without isolating intermediates, the sulfonamidated DET aqueous mixture is contacted with an aprotic organic solvent in the presence of a cyclizing unit such as ethylene glycol ditosylate or ethylene dibromide, thereby resulting in a cyclized sulfonamidated triamine compound. Thereafter the protecting groups are removed and the amine is alkylated, preferably within a single reaction vessel without isolation of intermediates.

Granted: 2004-03-30
Abstract: A compact, high performance exhaust assembly (50) for an internal combustion engine (20) or the like having a balanced chamber (52). Two substantially parallel inlet exhaust pipes (38, 40) are mounted to a first wall (74) of the chamber (52) and are axially aligned with, but independent of, two output exhaust pipes (54, 56) similarly mounted to an opposing second wall (76) of the chamber (52). Exhaust gas is discharged through the inlet pipes (38, 40), preferably in an out-of-phase relationship or alternating from one inlet pipe to the other. The exhaust gas passes a short distance through the chamber (52) and out of aligned outlet pipes (54, 56). The majority of the exhaust gas flows directly through the chamber (52) without significant expansion. The exhaust assembly (50) increases the power output of the engine.

Abstract: A method of invoking and cancelling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.

Abstract: Le support d'enregistrement d'informations optiques possède une couche de réflexion de signaux d'information à lecture optique. Le support se compose d'un substrat en plastique. Le substrat reçoit une coloration en utilisant un colorant afin que les informations enregistrées sur le support soient confirmées visuellement d'un simple coup d'oeil, et ce quelque soit le type d'information, par exemple, un programme de jeu, des informations musicales ou autre genre d'information. En général, le système optique d'un lecteur est affecté et le lecteur ne peut lire les données facilement lorsqu'une impureté telle que le colorant ou autre se mélange dans le substrat. L'influence d'un tel phénomène sur le système optique est éliminée en réduisant la taille des particules du colorant jusqu'à 50  mu m.

Filed: 1996-10-24
Granted: 2001-01-02
Abstract: The present invention provides a spring steel with excellent performance, characterized in that the spring steel is produced by making a spring steel contain an appropriate amount of at least one or more of Ti, Nb, Zr, Ta, and Hf, thereby generating fine inclusions including carbide, nitride ,sulfides and/or their complex compounds, to make the inclusions exert the effect of trapping diffusive hydrogen whereby the resistance to hydrogen embrittlement is enhanced, wherein the size and number of the coarse inclusions are regulated, thereby suppressing the decrease of the fatigue life. The spring steel can provide a valve spring or a suspension spring or the like, with enhanced strength and higher stress resistance, together with improved resistance to hydrogen embrittlement and fatigue.

Abstract: An interactive distance learning system is disclosed which is characterized by individual attention to each student.  A live lecture, transmitted from a remote location (100), is accompanied by questions (480) to gage comprehension by students.  The question and possible answers for student choice are graphically displayed on a video screen (186).  Affirmative supportive commentary is prepared prior to the lecture and prerecorded for each of the possible correct and inccorect responses.  Each response teaches, confirms and encourages the learning experience.  A processor (178), branching codes and a memory device (282, 286) can be used to create a large variety of responses to provide individual responses for students.  The transmitted interactive signal can be recorded (294) and remain fully interactive.  An extremely flexible, relatively inexpensive system is thus created which uniquely teaches and uniquely addresses the needs of every student.

Abstract: A doctor (10) is disclosed for creping tissue (T) from a surface (S) of a Yankee dryer (12). The doctor (10) includes a frame (14) and a support (16) which extends from the frame (14). A swing arm (18) is pivotally secured to the support (16) about a pivotal bearing (20). The swing arm (8) defines a further bearing (22). A pivot (24) extends through the further bearing (22) for rotatable movement relative to the swing arm (18) such that the pivot (24) is rotatably supported by the swing arm (18). A doctor (26) is rigidly secured to the pivot (24) for doctoring the tissue (T) from the surface (S) of the dryer (12). A blade (28) is removably secured to the doctor (26), the blade (28) defining an operative edge (30) which cooperates with the surface (S) of the Yankee dryer (12) for creping the tissue (T) from the surface (S) of the dryer (12). A loader (32) is operatively connected to the pivot (24) for rotating the pivot (24) within the further bearing (22) for loading the operative edge (30) against the surface (S) of the dryer (12). A blade angle changer (34) is operatively connected to the swing arm (18) for pivoting the swing arm (18) relative to the support (16), the arrangement being such that movement of the angle changer (34) selectively changes an angle (.alpha.) defined between the blade (28) and the surface (S) of the dryer (12). The operative edge (30) is disposed substantially along an axis of rotation (36) of the pivotal bearing (20), the arrangement is such that when the blade (28) wears due to contact with the operative edge (30) with the surface (S) of the dryer (12), the angle (.alpha.) is changed to optimize the creping without significantly altering the disposition of the operative edge (30) relative to the surface (S) of the dryer (12).
