Abstract: The present invention discloses high viscosity sustained release dental compositions, such as tooth bleaching or fluoride compositions, for treating tooth surfaces. For maximum results, an improved dental tray having reservoirs for holding the dental composition adjacent the desired tooth surfaces is preferably used in combination with the sustained release dental composition. The sustained release dental compositions include a high carboxypolymethylene concentration which results in very high viscosity. The high level of carboxypolymethylene makes dilution of the dental compositions from saliva difficult and time consuming so that the compositions stay within the tray reservoirs, thereby providing sustained release. The concentrated carboxypolymethylene adds a unique tackiness to the dental composition which helps retain and seal the soft tray material against the patient's teeth.

Abstract: Procédé et éjecteur amélioré destinés à produire des particules explosives ultrafines. Lesdites particules explosives, lorsqu'elles sont incorporées à un agent liant, ont la capacité de se propager en feuilles minces et elles ont une sensibilité très faible aux impacts et une sensibilité très élevée à la propagation. Un courant d'une solution de l'explosif dissous dans un solvant est soigneusement mélangé à un courant d'un non-solvant inerte de manière à obtenir un flux non laminaire des courants en appliquant une pression contre le flux du courant de non-solvant afin, par là-même, de faire diverger le courant lorsqu'il entre en contact avec la solution explosive, et en agitant violemment le courant combiné pour précipiter rapidement les particules explosives de la solution sous forme de particules ultrafines, généralement sphériques. Les deux courants sont injectés coaxialement à travers les orifices continus concentriques d'une tuyère dans une chambre de mélange. De préférence, le courant de non-solvant est injecté centralement par rapport au courant de solution explosive. Ledit courant de solution explosive est injecté en aval du courant de solution non-solvante et entoure ce dernier sur une distance assez importante, avant d'être éjecté dans la chambre de mélange.

Abstract: On réduit l'espacement des lignes au minimum et on augmente l'uniformité de l'espacement des lignes dans des transistors à film mince en utilisant une métallisation source/drain ayant une première couche relativement mince d'un premier conducteur et une seconde couche relativement épaisse d'un second conducteur. Le second conducteur est choisi de sorte qu'on puisse l'attaquer de préférence en présence du premier conducteur pour que celui-ci agisse comme barrière à l'attaque de l'agent d'attaque utilisé pour configurer la portion du second conducteur de la métallisation source/drain. Cette attaque s'effectue de préférence à sec. L'attaque à sec permet généralement un contrôle sensiblement meilleur de la largeur des lignes que l'attaque par voie humide. L'attaque du second conducteur peut s'effectuer par un procédé d'attaque à sec qui attaque la photoréserve sensiblement à la même cadence que le second conducteur de sorte que l'on obtient une pente sensiblement de 45° de la paroi latérale du second conducteur, ce qui améliore la qualité de passivation effectuée par le dépôt ultérieur d'une couche de passivation de conformation.

Abstract: In order to reduce the switch-on surge in current in the operation of an inductive load provided with a magnetizable core at an alternating mains current, in particular in pulse group operation, a switch-off-reset impulse is applied to this load following switching-off of the inductive load from the alternating current mains. This impulse has a polarity phased opposite to the last pulse group halfwave. In this way the remanent induction of the transformer core is shifted in a defined manner to lower values so that a defined remanence state of the iron core can be assumed when starting the next pulse group. This permits peak-current-free switching-on under any load and pulse period conditions. The remanent induction of the transformer core can also be maintained in the sector occurring immediately following switching-off of the inductive load, thus at the end of a pulse group. For this purpose voltage of reduced effective value compared to the load, in particular small voltage phases which are in phase with the voltage application prior to the switching-off moment, is applied to the transformer in the pulse group pauses.

Abstract: In a new process for the preparation of a supported catalyst for the polymerisation of  alpha -olefins, first a support gel (1) is prepared by introducing a sodium water glass or potassium water glass solution into a swirling stream of an aqueous mineral acid optionally containing aluminium ions longitudinally and tangentially to the stream, spraying the resultant silicic acid hydrosol in drop form into a gaseous medium, and allowing it to solidify to form a hydrogel, and freeing the resultant hydrogel, without prior ageing, from salts by washing and optionally from some of the water by extraction with alcohols and/or ketones, and then drying the hydrogel. This gives the support gel (1), which is ground and fractionated according to particle size. In a second process step, the support gel (1) is charged with chromium trioxide or with a chromium compound which can be converted into chromium trioxide, after which the resultant chromium-containing support gel (2) is heated at from 400 to 1100 DEG C for from 10 to 1000 minutes in an anhydrous gas stream containing oxygen in a concentration greater than 10% by volume. It is essential for the process according to the invention that the drying of the hydrogel to form the support gel (1) takes place in a high-speed drier within a maximum time of 300 seconds at an inlet temperature of from 200 to 600 DEG C. The supported catalyst prepared in this way gives homopolymers and copolymers of ethylene having excellent low-temperature toughness.

Abstract: In accordance with the invention, the distorted DTMF signal is regenerated. For this purpose, a regenerator is used which can be connected to the speech decoding system or can be integrated in this system. The DTMF regenerator corrects the distorted DTMF signals to form a standard DTMF signal shape. So that the device which contains the speech decoding system can be connected to terminals capable of standard DTMF, such as, for example, answering machines and the like, the regenerator contains a detector which detects the DTMF signal. The detector comprises a high-pass and a low-pass filter in order to separate the DTMF frequency groups, and a processing unit in which characteristics of the decoded signal such as autocorrelation and high-and low-band energy are determined and in accordance with these values a DTMF signal occurring is verified and a column and row tone are calculated and verified and from these tones a numerical or character value is formed and verified and transferred to the generator. In this generator, the delay occurring during the detection is corrected and a standard DTMF signal is generated as output signal in accordance with the verified numerical or character value having the correct length. <IMAGE>

Abstract: Non-carcinogenic asphalts and asphalt blending stocks are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the asphalt or asphalt blending stock and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic asphalts and asphalt blending stocks are then processed utilizing the conditions so established.
