Patent EP-0016806-A1 (EP)
Title: Oil reconditioning filter.
Inventor: THOMPSON BRUCE L
IPC: B01D24/00
Filed: 1980-02-25
Abstract: An industrial oil reconditioning system forces dirty oil through a three-stage filter which usually includes a first stage comprising a blend of relatively flexible fibers and rigid fibers, a second stage which is all flexible fiber material, and a third stage, preferably of animal fiber. As the oil is forced through the system, under pressure, the fibers of the first and second stages are compressed. The fibers of the first and second stages are cut to a length which causes a weaving or matting during compression to prevent channels from forming in the filter through which oil might pass without being cleaned. The heat of the oil may be precisely controlled at different points in the system to thin the oil, to break emulsions, and to vaporize contaminant fluids. The filtering materials and temperatures may be varied depending upon the type of oil and contaminants being processed. Most industrial oils can be satisfactorily cleaned with one pass through the system. A number of convenience features are built into the system.

Filed: 1980-04-25
Abstract: A field effect transistor of vertical structure includes source (2), channel (3) and drain (4) layers formed successively on an electrically-insulating substrate (1) and etched to form a mesa-like structure. A layer of dielectric material (7) covers at least part of the edge of the channel layer (3) around the periphery of the mesa. The drain electrode (16) is formed over the edge of the channel layer so that an electrically conducting channel can be induced between the source and drain layers at the edge of the channel layer. The transistor structure is particularly suitable for arrays of such transistors adapted for X-Y addressing.

Abstract: A modified polyurethane adhesive composition characterized by its improved viscosity and high initial bond strength contains an isocyanate-terminated prepolymer or a fully reacted polyurethane and a carbamate ester which is compatible and not reactive with the prepolymer or polyurethane. The resultant adhesive is suitable for laminating many types of substrates. In a preferred embodiment the prepolymer is employed with the carbamate ester in a reactive hot-melt adhesive for use in bonding flexible substrates.

Abstract: To simplify the yarn feed on knitting machines, one or more deflecting mechanisms (2) are proposed, which are guided over the widths of the needle beds (1) and have one or more yarn driver devices (21) arranged on them. The driver devices can be bores (21) arranged at regular intervals on the deflecting mechanisms in the form of a band, cable or the like. These yarn guides designed as deflecting mechanisms can be arranged in a space-saving way above and also below the needle bed or needle beds. However, they must be so guided in the region of the working needles that they feed the yarn as near as possible to and centrally above the needle beds. <IMAGE>

IPC: G05D23/02
Filed: 1980-10-22
Abstract: A thermally responsive valve (10) for valving adjacent first (20) and second (22) fluid ports is disclosed which prevents harmful fuel vapors from adversely affecting the valve power element (12). An elongated valve member (82) is movably contained within a housing fluid chamber (18) and spring-biased toward a closed position whereupon a first seal ring (96) located around the valve member engages with a valve seating surface (70) located intermediate the two fluid ports. When predetermined temperatures are encountered, a thermally responsive power element (12) connected to the lower end of the valve housing overcomes the biasing force of the spring (92) and moves the valve member to an open position in which the valve surface is spaced from the valve seat, thereby permitting fluid communication between the two ports. A lower portion (90) of the valve member extends beyond the fluid chamber and abuts with an output rod (60) of the power element. A stationary seal ring (72) is mounted in a housing counterbore (76) and engages the periphery of the valve member lower portion for sealing the fluid chamber from the thermal power element.

Abstract: A method is described for preparing a solid fuel, in either powder or briquette form, for use in small furnaces. 
     The fuel has a relatively uniform heating value of 12,000-14,000 Btu per pound and is prepared by crushing and grinding coal to less than 200 mesh and drying and oxidizing the coal with a hot gas containing a trace of oxygen to a dried moisture content of 1-15%. Selected quantities of additives having approximately the same fineness are combined with the coals to minimize the effects of sulfur, to improve combustion and ash properties, to maintain fluidity of the solid fuel in powder form, to inhibit moisture pick-up, and to prevent auto-ignition and spontaneous combustion during storage of the solid fuel.

IPC: H02K17/02
Filed: 1980-10-08
Abstract: The stator (21) of the motor is of annular form, with generally radial slots (22) which receive the energising windings. The squirrel cage of the rotor has a magnetic component (16) and a conductive component comprising inner ring (10) and outer ring (12) joined by bars (14). The bars (14) are curved so as to follow a path with a higher radial component at the inner end than at the outer end. This reduces perceived noise by avoiding sharp registering of the rotor bars with the stator slots, and also by providing a more uniform ratio of magnetic to conductive material in the rotor at different radii around the rotor axis.

Abstract: A scroll-type fluid displacement apparatus, in particular, a compressor unit, is disclosed. The apparatus includes a housing having a front end plate member (11) and fixed and orbiting scroll members. Each of the scroll members have an end plate (251,261) and a spiral element (252, 262). Both the spiral elements interfit at an angular offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets. A driving mechanism, including a drive shaft (13) and a rotation preventing mechanism (371, 372), are disposed within the housing and are connected to the orbiting scroll member to effect the orbital motion of the orbiting scroll member by the rotation of the drive shaft. The front end plate member is comprised of a front end plate portion (11a) in which is formed an opening (111) for passage of the drive shaft, and an annular sleeve portion (11b) extending from a front end surface of the front end plate portion for surrounding the drive shaft.

A separator is positioned between the first frame member and the second frame member. A first sealing means contacts a side of the first frame member and one side of the separator. Contacting the second frame member is a second sealing means having a raised portion which also contacts a side of the separator. Pressing means are provided which press the frames together against the sealing means and the separator to form a substantially fluid-tight seal. The novel electrolytic cells provide the advantages of simultaneously:
     a. controlling gasket compression pressures,   b. controlling gasket frame surface structural forces,   c. efficiently forming a seal, and   d. preventing gasket slippage.
