A control system for a continuously variable transmission for a motor vehicle has a transmission ratio control valve (TR) for controlling the transmission ratio. The transmission ratio is controlled in accordance with a desired transmission ratio. On using an air conditioner of the vehicle, the desired transmission ratio increases, so that necessary engine power can be obtained. The desired transm...

Der Schusspulenwechsler (1) besteht aus einem Spulenmagazin (14, 15), das die Lieferspule (11) und wenigstens eine Reservespule (12, 13) enthält. Mit einem Fühler (6) wird die auf der Lieferspule (11) vorhandene Fadenmenge dauernd überwacht. Erst im Zeitpunkt, wo die einstellbare Mindest-Fadenmenge der Lieferspule (11) erreicht ist, wird von einer Verbindungsvorrichtung (5) der Faden der Lieferspu...

A method and an assembly for decontaminating a material. The material is charged into a container (2), where at first steam (4) is introduced and fluids including some contaminants are removed. Then extractant (6) is introduced into the container (2), and fluids (8) comprising condensation water, extractant and contaminants are removed. Then the material is stripped with vapour. The dry or slightl...

In a process of the preparation of flexible polyester urethane foams by reacting polyester polyols having at least two hydroxyl groups in the molecule with at least difunctional polyisocyanates in the presence of water, optionally of physical blowing agents, catalysts, stabilizers and optionally of other conventional additives, the following two components are added for catalysis in the form of a ...

A device for detecting differences in color of a material to be inspected, which device comprises a first light source emitting light of a first color and a second light source emitting light of a second color, an optical system adapted to project portions of the light emitted both by the first and the second light source onto first and second spaced apart measuring regions respectively, each meas...

The cyclopropanecarboxamides and enantiomer pairs of the formula (I) consisting of these active compounds and the enantiomers corresponding to them and the use of the novel compounds as agricultural fungicides are disclosed.

A self-running robot placed on a cart (6) is moved from one cell to another (1-9) to perform various predetermined machining proceses, guided by a signal current through a guide wire (c) installed on the floor. A node map showing the distance between any two of the cells (a) is stored in the memory of a CPU (e) and the robot (b) is guided so that it takes the shortest route between the successive ...

The present invention is a manufacturing method of a rigid or semi-rigid foamed material which comprises a foaming process to make a practically thermoplastic foamed material wherein isocyanate component is reacted with polyol component in the presence of organic foaming agent and/or water in a condition that a quantity of the isocyanate component is present in excess of the stoichiometric equival...

An improved process is provided for the preparation of siloxane-oxyalkylene block copolymer surfactant compositions which utilized a hydrosilation reaction with high boiling point polar polyols as the reaction solvent. The reaction solvent need not be removed from the block copolymer, particularly when the block copolymer is used as a surfactant for polyurethane foam formulations. Dipropylene glyc...

This invention relates to a system for controlling the motion of a self-contained unmanned vehicle (robot car) capable of independently travelling, on the basis of previously specified data, to convey parts, finished products, etc. in a factory or similar location. The invention has at least one memory device (10) for storing the coordinate data of the nodal reference points (Ni) on the travel pat...

A method of grinding a workpiece (24) which is susceptible to deflection and/or deformation when grinding is carried out by relatively infeeding a grinding wheel (20) to keep the wheel face and work surface in relative rubbing contact at an interface region, the method comprising continuously determining the force exerted by the wheel (20) on the workpiece (24) at the interface region as grinding ...
