Title: Candle reshaper
Inventor: FALLE DAVID E
IPC: C11C5/00
Filed: 2003-03-07
Abstract: A candle top and reshaper fit snuggly over a candle. The reshaper includes interior and straight tapered, curved or otherwise angled sidewalls that when fitted over a burning candle, the softened candle rim and sides are forced back into the center of the candle, causing the softened rim to reshape and prolong the candle bum time. Alternatively the walls of the reshaper are vertical and force the softened sides and rim down and into the center. The reshaper also protects the softened and liquefied wax of the candle from dirt and insects during the re-cooling process and the top provides a decorative cover when candles are stored.

Title: Dispenser for the discharge of flowable media
Inventor: GREINER-PERTH JUERGEN
IPC: B05B11/00
Filed: 2003-04-15
Abstract: A dispenser for flowable media is provided, which operates in user-independent manner with respect to the pressure buildup and dosage quantity. On pressing on an operating head (35) a piston rod (29) is forced into a pump cylinder. As the pump chamber (52) is sealed by means of a delivery valve (51), which operates in path-dependent man-ner as a slide valve, under the action of a spring (42) pressing on the piston collar (43), a pressure builds up in the pump chamber (52), which is released following a predetermined length of travel on opening the de-livery valve. A relatively constant pressure can be obtained over the en-tire discharge phase through the pretension of spring (42).

Abstract: Hand interfaces (11), (111), (188), (201a), (201b), (202a), (202b), (204), (211), (311), (411), (511), (611), (711), (811), and (911), which improve the performance of many items including: racquets for tennis and other sports; rotary hand tools such as screwdrivers; hockey sticks; and kayak oars. Relative rotation between one of the hand interfaces and a corresponding implement is selectively stopped, and torque is selectively transmitted between the hand interface and the implement, when a user squeezes the implement's handle. The hand interface can be rotated in either direction on the implement, and relative movement stopped at an infinite number of positions.  The hand interface amplifies the opposing effects of either a firm grasp or a relaxed grasp. Tactile indicator systems (36) with (38), and (236a,b) with (238a,b), glove (204), as well as handle grips (611), (711), (811), and (911) which rotate on noncircular shafts, enable users to accurately determine rotational positions of the implement to the hand interface. For additional ease of use, adjustable end-stop systems (273a,b) with (275a,b), or (73f,b) with (86f,b) limit the range of rotation between the hand interface and the implement

Abstract: Plan de cuisson en céramique à plaque en vitrocéramique qui porte sur sa face inférieure des éléments de chauffe placés au-dessus d'une couche d'isolation pour la chauffe directe. Le plan de cuisson est divisé au moins en une partie interne de plan et une partie externe de plan qui portent des éléments de chauffe individuels pour chaque partie de plan. Ces éléments de chauffe peuvent être commutés et réglés pour ce qui est de leur puissance à l'aide d'une commande, en fonction des valeurs de température détectées par les capteurs de température associées aux parties de plan. L'utilisation de pistes conductrices concentriques ou plus précisément d'éléments de chauffe annulaires plats permet la fabrication d'un plan de cuisson de structure simple dont la surface est utilisée de manière optimale et qui permet donc d'obtenir une bonne efficacité de chauffe pour une chauffe homogène des parties de plan.

Abstract: L'invention concerne un procédé et un système visant à déterminer la cavitation d'une pompe. Selon le principe de l'invention, les changements de pression fluidique dynamique d'une pompe sont surveillés puis comparés à une pression d'avertissement de cavitation déterminée. La pression de cavitation déterminée est définie comme un pourcentage connu d'une pression de non cavitation connue. La cavitation fluidique est déterminée lorsque le changement de pression dynamique fluidique descend en dessous de la pression d'avertissement de cavitation déterminée. Dans un autre aspect de l'invention, la durée de vie opérationnelle restante d'un joint d'étanchéité mécanique peut être déterminée par maintien de la durée totale de cavitation fluidique et par réduction de la durée de vie prévue par la durée opérationnelle de la pompe et la durée de cavitation de la pompe.

Title: A process for preparing a fuel additive and the additive
Inventor: AHONEN HEIKKI
IPC: C10L1/08
Filed: 2002-06-10
Abstract: The invention relates to a method for manufacturing a fuel additive and to the additive. It relates particularly to a lubricant additive that is highly suitable for use as an additive in connection with diesel engines. According to the method, saturated fatty acids with a high melting point are separated by cooling from a fatty-acid mixture, the said fraction of fatty acids with a high melting point being esterified and/or animated to form a mixture of more than three esters and/or amines and the mixture thus obtained being re-mixed with that part of the original fatty-acid mixture from which the fatty acids with a high melting point were separated and the necessary amount of this last-mentioned mixture being mixed with fuel to form a lubricant. The separation of the saturated fatty acids with a high melting point takes place by passing the mixture through a cooling heat-transfer surface, to which the fatty acids adhere, and by removing the fatty acids from the surface by raising its temperature.

Le précurseur de second noyau est poussé contre la grenaille de manière à déformer la grenaille pour qu'elle remplisse un volume avant du précurseur de blindage et fasse office de premier noyau présentant une déformation moindre (si toutefois il existe une déformation) que celle du précurseur de second noyau. Une partie arrière du précurseur de blindage est déformée pour contenir le précurseur de second noyau qui devient le second noyau. Les formes de réalisation préférées sont configurées sensiblement sous forme de recharges instantanées pour des balles existantes. Une forme de réalisation d'une balle de précision comprend un noyau arrière en plomb et un noyau avant très léger (en poudre de carbonate par exemple). Une forme de réalisation non toxique comprend un noyau avant en étain et un noyau arrière plus dur.
