Patent EP-0221249-A2 (EP)
Inventor: TSAI MEI-YUAN
IPC: C10M111/04
Filed: 1986-07-28
Abstract: A parting composition contains alpha-olefin oligomer having a viscosity in the range of about 1-3 cs at 450°F. The parting composition in one aspect can be blended with a fatty ester or fatty alcohol. The parting composition is useful for the continuous casting of molten metal such as aluminum or aluminum alloy, which may contain lithium. A casting process for continuously casting molten metal, particularly containing lithium, through a mold or header includes applying a parting lubricant containing alpha-olefin oligomer. The lithium-­containing alloy may be continuously cast by direct chill with a direct chill coolant which is a moisture barrier liquid employing the disclosed parting compositions.

Abstract: An inductive magnetic field article surveillance system includes a generator for a first magnetic field. Articles to be monitored include a structure responsive to the first magnetic field for deriving a second inductive magnetic field having a predetermined frequency. An inductive magnetic field receiver responsive to the second magnetic field includes a receiver coil arrangement for deriving a signal that is a replica of variations of the second magnetic field. Processing circuitry responds to the receiver coil arrangement to derive an indication of the presence of the structure. The receiver coil arrangement includes first and second coils likely to have different responses to the second magnetic field. Only one of the first and second coils is connected to the processing circuitry at a time, as a function of which coil is supplying a signal at the predetermined frequency of the second field to the processing circuitry for at least a predetermined time interval.

Abstract: This invention provides a process for producing an acetyl-substituted aromatic compound by making an aromatic compound react with acetyl fluoride in the presence of substantially anhydrous hydrogen fluoride as a catalyst. 
     It has been already known to acylate an aromatic compound with an acid fluoride in the presence of boron fluoride or hydrogen fluoride and boron fluoride as a catalyst. It has been found that, in a reaction of an aromatic compound with acetyl fluoride, even when hydrogen fluoride alone is used as a catalyst, the intended acetyl-substituted aromatic compound can be obtained in excellent yield and further the complex compound formed can be decomposed without difficulty and the hydrogen fluoride catalyst can be easily recovered.

Abstract: A process for the manufacture of void-free prepreg sheets formed by  the impregnation of a reinforcing cloth (e.g. glass fibre cloth) with a  solution of a thermosetting resin (e.g. epoxy resin). In the process,  the reinforcing cloth is first prewetted with a liqid medium containing  a solvent for the resin which has a viscosity less than that of the  solution of thermosetting resin. The prewetted cloth is impregnated  with a solution of the resin and then heated to remove the solvent and  cure the resin. The prepreg sheets are used in the manufacture of  printed circuit boards.

Abstract: For the reproducible formation of layers of material by evaporation or sputtering or chemical deposition, etc. and/or for the treatment of material layers, in particular semiconductor layers by diffusion or ion implantation with at least one parameter of the layer of material being measured during the layer formation and employed as a measurement signal in a digital evaluation circuit for the on-line control of the layer formation process, a test signal having a predetermined variation or frequency spectrum or a predetermined frequency series is applied to the layer of material for a short time at specified time intervals. From the respective test signal (current signal) and the associated measurement signal (voltage signal), a process computer in the digital evaluation circuit determines impedance components which can be separated from one another in time, which have mutually differing values or ranges of values of time constants and possibly also of conductivities and which are in total characteristic of the current flowing through the layer being formed, namely the current through the homogeneous material regions of the layer (intrinsic current i2), the current flowing via the particle interfaces (grain-boundary current i3) and the current flowing via the layer surface (surface current i1).

Abstract: A temperature compensated carburetor having a fuel metering system including a variable restriction needle gate valve (42) for varying the effective flow cross-sectional area of the main and/or idle fuel supply duct to modulate the flow rate of fuel to the carburetor venturi mixing passage (16). The needle gate valve (42) is made of plastic material having a much greater coefficient of expansion than the aluminum carburetor body (12) in which it is adjustably mounted such that differential linear expansion and contraction of the needle valve (42) relative to the carburetor body (12) in response to ambient temperature changes varies the flow-controlling cross-sectional area of the fuel duct inversely relative to ambient temperature changes. The needle valve (42) is a rod-like body with a threaded cylindrical mounting portion (60) at one end threadably secured in a threaded bore in the carburetor body (12). A reduced diameter extension of the needle body extends axially away from the mounting end of the needle body and has cylindrical stem portion (70) slidable in another bore (52) of the carburetor body (12). The needle body is unrestrained linearly from the free end of the stem portion (70) to the needle body mounting portion. The free end of the stem is movable in a jet fuel feeding passageway (28, 30) of the fuel duct to thus vary the flow controlling cross-section thereof.

Abstract: When forging toothed wheels from solid metal, there is the difficulty that, due to the friction of the blank material on the die, the axial end regions of the toothed wheel will not be fully formed, with the result that the load-bearing capacity of the teeth in the end regions is limited. It is the object of the invention to specify a forging method by which toothed wheels with teeth of a high load-bearing capacity can be manufactured in a single-stage production process. In the method according to the invention, rams (20, 23) enter the die (12) from both sides, the blank (27) thus being deformed from opposite sides. This leads to material flow even into the end regions of the toothing impression (13). In a single-acting press, the die (12) is arranged in a manner which allows vertical displacement and one ram (20) is stationary during the pressing operation. It is possible to produce toothed wheels with or without a central hole in a single work step.
