Title: Method of and device for winding the inductive coils equipping electrical apparatuses such as transformers
IPC: B65H54/80
Filed: 1982-11-19
Granted: 1986-06-11
Abstract: An insulated wire is wound into a cylindrical coil by being continuously introduced into an annular space between a cylindrical core and a cylindrical sleeve coaxially surrounding same above a supporting surface which is rotated about their axis at an angular velocity W, the wire being fed in at a linear speed V. A processor is programmed to vary the ratio V/W according to the relationship (V/W)i= pi [D+2d)(ai-1)] where D is the diameter of the core, d is the wire diameter and ai is an integer representing the order number of the ith turn of a spiral path, counted from the core surface, along which the wire is laid in a succession of flat layers piled one atop the other. Each layer consists of n contiguous turns following one another in a radially outward direction in odd-numbered layers and in a radially inward direction in even-numbered layers, with decrementation or incrementation of the ratio V/W at the end of each turn. The discharge end of a feed tube is raised above the supporting surface, upon the completion of each layer, by an incremental distance equal to the wire diameter d to accommodate the next layer.

Abstract: A machine for producing blocks or elements includes a base board 13 which defines a surface to close the lower end of a mould box 12. Extending into the upper end of the mould box is a frame 14 forming part of or secured to a throat portion 11 which depends from a hopper 10. Means not shown is provided to raise the mould box following compaction of the material in the throat portion and mould box, above the lower end of the frame 14, to eject the compacted material from the box. Further means is provided to raise the throat portion and frame by a limited amount to cause fracture of the compacted mass of material in a plane generally defined by the frame. The plug of compacted material in the frame and throat portion until vibrated, prevents material in the hopper from falling through the throat portion.

Granted: 1988-08-10
Abstract: A process for biochemical optical resolution of 4-hydroxy-3-methyl-2-(2'-propynyl)-2-cyclopentenone, which comprises allowing esterase produced by microorganism or esterase of animal pancreas to act on an organic saturated or unsaturated C1 - C18 carboxylic acid ester of ( 9E)-4-hydroxy-3-methyl-2-(2'-propynyl)-2-cyclopentenone to effect asymmetric hydrolisis for obtaining optically active 4-hydroxy-3-methyl-2(2'-propynyl)-2-cyclopentenone and its enantiomer. This process is simple in comparison with a conventional process of optical resolution according to an organic synthetic chemistry principle and does not require expensive optically active reagents, thus being industrially quite advantageous.

Filed: 1985-02-07
Granted: 1990-11-22
Abstract: A particle classifier includes a generally cylindrical, air and fine particles permeable cage having a closed top and open bottom mounted to a central drive shaft. A casing surrounds the cage and defines a volute air passage about the cage with an air separation zone between the volute and the cage. A generally tangential air inlet is provided in casing volute and a material inlet is provided in the the upper end of the casing. A stationary chamber is positioned below the cage for the air and fine material which enter the cage. From the chamber, the air and fine material is directed to cyclone separators in which the air is separated from the particles. A hopper is positioned below the chamber for collecting coarser material which fails to enter the cage. The size of the volute can be adjusted by a vertical partition within the casing. The partition allows flexibility in setting the air velocity. Means are provided for stream-ling the air flow from the air inlet to the cage and retaining particles in the separation zone. In one case. louvers are provided for these two purposes, and in another case a screen is provided between the volute and particle separation zone.

Abstract: A method of fabricating a resistor in polysilicon and a semiconductor element suitable for use as a load resistor in a static memory. In the method, after the polysilicon has been doped, the device is annealed by exposing it to a rapid increase of ambient temperature (up to between 900 and 1200 DEG C), maintaining the high ambient temperature for a controlled time (about 5 seconds) and then lowering the ambient temperature at a rapid rate. This decreases resistance by one order of magnitude and significantly decreases the temperature activation energy of the resistor. This permits static memory cells to retain data even through the cell has high leakage currents, thereby improving final test yields.

Abstract: Apparatus is disclosed for grinding the edges of a glass sheet which is positioned on a motor driven rotary table. The apparatus includes a grinding disc mounted to rotate in a toolholder which may be moved in relation to the axis of rotation of the rotary table by a constant torque motor so as to apply a constant grinding pressure between the grinding tool and the glass sheet. A plurality of manometer capsules or other pressure measuring devices whose voltage outputs depend on applied pressure, are used to produce signals to regulate the constant grinding force. The toolholder is movably mounted on a larger positioning carriage which can also be moved in relation to the axis of rotation of the rotating table in order to compensate for irregular glass sheet shapes. This positioning is effected by signals from a distance to voltage converter fed into an adjustment circuit which drives a positioning motor.

Abstract: The radius of curvature of a tooth surface is increased and decreased repeatedly from a point on the pitch circles toward the addendum and deddendum without being varied monotonously. The centre of the radius of curvature positioned on the pitch circles (2, 4) at a point at which the radius of curvature is minimal. The curvature of the tooth profile curves (1, 3) is represented by a nonmonotonously varying, continuous and differentiable function with the locus of the curvature centre forming a series of continuous curves which is usually located in the vicinity of the pitch circles. Due to the tooth profile the contact ratio of the gears is set to at least unity by gradually approximating the relative curvatures of the surfaces of the gear teeth from values of involute tooth profiles to that of Wildhaber-Novikov's tooth profiles. An increase in the surface pressure and bearing stress is reduced by reducing an operating pressure angle to a relatively low level.

Title: Polarized magnetic drive for electromagnetic switching device
Inventor: DIETRICH BERNHARD
IPC: H01F7/16
Filed: 1987-09-15
Granted: 1995-01-25
Abstract: The magnetic drive of an electromagnetic contactor comprises two spaced coils (10, 11) having a coaxial bore in which an armature (14) is mounted for reciprocal movement between two end positions. A control slider (21) is disposed between the coils (10, 11) with its two sides forming stops for the armature (14). When the armature (14) is changed over from one to the other end position, the slider is also changed over and limits in the mid-position the return movement of the armature (14) from the respective end position. In a contactor designed for tri-stable operation, undesired movement of the armature beyond the mid-position is avoided, which could otherwise lead to an inadvertent change-over of the armature (14) to the other end position. If the contactor is designed for monostable mid-position operation, oscillation of the armature (14) about the mid-position is prevented, so that this mid-position is stabilized.
