Patent CA-2158562-A1 (CA)
Inventor: LUCKHARDT WOLFGANG
IPC: B23Q1/00
Filed: 1994-04-05
Abstract: An arrangement for pressing-in joining parts such as nuts into plate-shaped components has a top (16) and a bottom (18) housing part movable with respect to each other within limits and prestressed away from each other by the force of a spring. The bottom housing part (18) has a joining part channel (22) to which joining parts may be supplied one by one through a lateral supply opening. A die (20) fixed to the top housing part (16) extends into the joining part channel in order to move a joining part located inside the channel from an initial position adjacent to the supply opening to a working position adjacent to the open end of the channel and to press the joining part into the plate-shaped component when the top and bottom housing parts are moved relative to each other. The pressing-in arrangement is designed as an integral module that may be mounted on a machine part by means of a rapid action coupling (12). The pressing-in arrangement thus represents a mobile unit which has a plurality of possible different applications.

Filed: 1994-03-24
Abstract: The invention is a multi-phase, sheeted chewing gum product, a method and an apparatus for making such a product. The product includes a first mass of a chewing gum formed in a generally flat sheet and a second mass of a confectionery product having a different color than the first mass. The second mass is smaller than the first mass and is embedded in the first mass so as to be visible with the first mass from the top surface of the chewing gum. The method includes the steps of forming the first mass into a slab with a generally flat surface. The second mass is formed into at least one piece which is brought into contact with the flat surface. The slab and the piece are pressed to produce a generally flat sheet which is cut into segments of a desired width, length and shape.

Title: Lubricant oil composition
Inventor: MATSUSHITA SHOUZOU
IPC: C10N10/04
Filed: 1995-12-21
Abstract: A lubricant oil composition comprising a minor portion of calcium sulfonate(s), barium sulfonate(s), or mixture thereof being neutral or having the total base number of 100 mg KOG/g or less, and straight chain univalent fatty acid(s) having 8 to 18 carbon atoms and a major portion of a base oil of mineral oil series and/or synthetic oil series, said base oil having a kinematic viscosity of to 500 mm2/s at 40°C.      The lubricant oil composition of the present invention exerts excellent separation properties from a cutting fluid prepared by diluting a water-soluble cutting fluid. Therefore, the composition so readily separates and floats in a reservoir tank for the cutting fluid that the composition can be removed simply by means of an oil skimmer and the like. Thus, the properties of the water-soluble cutting fluid can be maintained for a long term, with no occurrence of poor work environment due to rot and so on.

Title: Preparation of high-impact and stable encapsulated flavors for frozen or refrigerated desserts and products resulting therefrom
Inventor: GRAF ERNST
IPC: A23L27/00
Filed: 1994-05-11
Abstract: This invention is directed to a method for preparing frozen flavor capsules as well as a method for incorporating these flavor capsules into low-fat frozen or refrigerated desserts. The invention also encompasses the capsules themselves, as well as dessert products incorporating these capsules. The capsules are prepared by first forming discrete composition capsules having a flavor encapsulated in an oil, and then freezing these capsules to solidify the oil and form discrete frozen solid flavor particles. Because the oil is essentially a liquid at ambient temperature, the oil liquifies in the mouth upon consumption, providing a balanced flavor release from the previously protected flavor capsule.

Abstract: Cette invention concerne un procédé de fabrication, d'assemblage et de production d'une bande en treillis métallique (90), laquelle possède des bords unitaires orientés verticalement et dotés sur leur longueur de surfaces en fil aplati et tissé hélicoïdalement. Ce système permet d'assurer l'entraînement dynamique et par friction de la bande à l'aide d'une surface d'entraînement rotative sensiblement cylindrique (95), laquelle se trouve dans une voie courbée hélicoïdale (92), la bande étant libre de tout dispositif d'entraînement mécanique lorsqu'elle se trouve dans la voie hélicoïdale. Un contrôle de la tension est exercé sur la bande et dans le sens de la longueur lorsqu'elle se trouve hors de la voie courbe hélicoïdale, de manière à obtenir le contact d'entraînement par friction souhaité avec la surface d'entraînement. Une voie de circulation externe (101) de la bande, située entre la sortie et l'entrée de la voie courbe hélicoïdale, permet d'obtenir un réseau de parcours de bande sans fin. L'accroissement du mouvement de la bande, à partir de la voie courbe hélicoïdale vers la voie de circulation externe (101), permet d'augmenter l'effort de traction dans le sens de la longueur sur le périmètre externe de la bande lorsqu'elle se trouve dans la voie courbe. L'accroissement de l'effort de traction sur le périmètre externe entraîne un accroissement de la force de constriction transférée au périmètre interne de la bande. Cela permet d'accroître la force d'entraînement dynamique et par friction le long du périmètre interne de la bande qui se trouve en contact avec la surface d'entraînement rotative sensiblement cylindrique.
