Title: Conductive coatings and foams for anti-static protection, energy absorption, and electromagnetic compatability
Inventor: WILEY ROBERT E
IPC: H05K9/00
Filed: 1986-04-24
Granted: 1991-01-22
Abstract: ABSTRACT         Improved compositions are disclosed which are useful in providing a conductive layer of coating on a surface to provide protection against harmful electrostatic discharges.  Also disclosed are compositions useful in absorbing and dissipating mechanical and electromagnetic energy and preventing electrostatic build-up; these compositions also provide electromagnetic compatability.  The compositions contain elemental carbon and a polymeric matrix or binder.  The improvement comprises employing a unique ground calcined, coal-based coke which approaches graphite in terms of its performance as a conductive additive or pigment but which does not possess the disadvantages associated with the use of graphite.  The unique coke employed in the compositions and methods of the present invention has a level of graphitic structure which approaches that of a true graphite.          This level of graphitization can be most easily recognized by utilizing x-ray powder diffraction.  More specifically, when the value of Ec or the inverse carbon peak width (the 002 peak) is measured for this material using Mo K.alpha. radiation .lambda. = 0.71.ANG. , the value is in the range of about 27 to about 80, and preferably about 28 to about 75.  The final compositions employ a polymer resin or matrix system as a binder.  The invention also relates to the method of applying the compositions to protect the article and reinforce the substrate, and the resulting coated articles, particularly containers for shipping and storage of electronic components and magnetic information-storage materials.  The conductive coating may also add strength to the containers.  The compositions may also be used to absorb both mechanical and electromag-netic energy thus providing EMC, and dissipate static electricity, thus preventing electrical static build-up.

Abstract: ABSTRACT OF THE DISCLOSURE The plastic molded article is produced by heating a mold by contact with a preheated salt bath.  The salt bath is readily  maintained  at  a  uniform  temperature  and   is self-insulating for energy efficiency.  A noncontact infrared sensor monitors the mold cavity temperature while in the salt bath, and the mold is removed from the bath when the proper mold temperature is reached.  A charge of plastic powder is introduced into the mold by clamping the mold to a powder slush box with the mold cavity confronting the opening of the box.  The mold and box are then simultaneously rotated to pour the plastic charge into the mold.  The plastic charge forms a skin on the cavity surface and additional plastic material may be built up to provide additional thickness.  The mold and box are then separated; the mold is then postcured and cooled, whereupon the finished article may be removed from the mold.

Title: Electromagnetic device for reducing vibration in a rotary machine fitted with fluid bearings
Inventor: HABERMANN HELMUT
IPC: H02K7/08
Filed: 1987-12-30
Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE The electromagnetic device comprises at least one compen-sation ring placed in the vicinity of the fluid bearing and mounted relative to the rotor by means of an active radial magnetic bearing whose electromagnet windings are powered as a function firstly of the signals delivered by a position detector for detecting the position of the compensation ring relative to the rotor, and secondly of the signals delivered by at least two vibration detectors disposed on the casing of the machine and having nonparallel sensitivity axes which are perpendicular to the axis of the rotor. The signals delivered by the vibration detectors are applied to a high-gain narrow-band selective feedback circuit whose central frequency is synchronized with a reference frequency fo. The compensation ring is of relatively small mass and serves to exert a rotary compensation force on the rotor via the radial magnetic bearing, which force is equal to the centrifugal force due to the cut-of-balance mass of the rotor but which is 180° out of phpase relative thereto, thereby reducing casing vibration while expending little energy.
