  • Patent number: 4008928
    Abstract: A self-aligning pod bearing assembly includes a cylindrical casing forming a socket for a bead-shaped porous bearing which is urged against the socket by means of a resilient bearing retainer which fits between a shoulder portion of the casing and the spherical bearing. The inside of the casing is filled with wicking material exposed through the bearing retainer to an oil slinger mounted for rotation with the shaft adjacent the end of the bearing contacted by the retainer and another oil slinger rotationally mounted on the shaft adjacent the other end of the bearing. In the preferred embodiments the outer diameter of the casing is formed by the same casing member which forms the interior bearing socket thus insuring coaxiality of the nominal bearing axis and the outer diameter of the casing.

  • Patent number: 4009232
    Abstract: Discrete carbon microspheres having a particle diameter on the order of 1-20 .mu. are obtained by a process involving the steps of homogeneously mixing a pitch having a softening point of 70.degree. - 250.degree. C, a nitrobenzene-insoluble content of not more than 25% and an H/C ratio of 0.2- 1.0 with an aromatic solvent compatible with said pitch and dispersing the resultant mixture in an aqueous solution of a surface active agent with agitation and at a temperature to maintain the viscosity at 200-5000 cps to form microspheres of the pitch/solvent mixture. The dispersion is then cooled to solidify the microspheres. The microspheres 1-20 .mu. in diameter are then separated from the solution and from the finer particles and contacted an organic solvent which is incompatible with the pitch to extract the first-mentioned aromatic solvent from the microspheres.

  • Patent number: 4008965
    Abstract: A method and device for use in detecting a precise focussing point, which comprises the steps of: placing a photoelectric element on an optical path or optical axis of a lens of a camera; converting the information of the precise focussing point for a photographic object into a frequency variation of an A. C. signal; feeding said signal having varying frequency to a highly sensitive frequency detector such as a resonance circuit, a tuned amplifier, or frequency-amplitude convertor having acute frequency characteristics; and detecting the precise focussing point with high sensitivity by means of the output thus obtained; whereby the aforesaid functions may be satisfactorily performed, irrespective of the variation in the luminance of the object and whereby the focus of the lens may be brought into precise conformity to the predetermined plane (i.e., the position corresponding to a film).

  • Patent number: 4004950
    Abstract: In a first step, the semiconductor material is doped in a known manner with impurities having a given conductivity type and a given concentration profile. In a second step, the material is maintained at a high temperature, bombarded with a beam of particles which are accelerated with a given energy so as to penetrate into the crystal during a predetermined time interval. The resultant migration of impurities produces an increase in the impurity concentration irrespective of the sign of the initial concentration gradient within a zone adjacent to the zone of stopping of the particles.

  • Patent number: 4002276
    Abstract: The donning of surgical gloves is facilitated by inflating the surgical glove with the cuff open so that the surgeon may insert his hand into the glove while inflated and then deflating the glove around the surgeon's hand. The glove is mounted in a glove package with the cuff of the elastomeric surgeon's glove stretched around a ring. The ring with the glove so mounted is mounted at the mouth of a tube which telescopes into a larger tube making a sliding air seal with the larger tube. When the smaller tube is withdrawn from the larger tube, the reduced air pressure that results within the chamber defined by the tubes sucks the glove into the chamber and inflates it in the chamber. After the surgeon has inserted his hand into the inflated glove, the inner tube is then reinserted into the outer tube to increase the pressure within the chamber above atmospheric causing the cuff of the glove to explode off the ring on which it is mounted and snap around the surgeon's wrist.
