Abstract: Abstract of the Disclosure A method of making a unitary silicon nitride comprising object and tool is disclosed.  A uniform powder mixture of Si3N4 containing SiO2 as an oxide coating, 4-12% by weight Y2O3, and .50-2.5 Al2O3 is prepared.  The mixture is hot pressed at a temperature of 1,680-1,750°C under a pressure and for a period of time sufficient to produce at least 99.0% (preferably at least 99.5%) of full theoretical density in the mixture to form a pressed object.  The heating and pressure is then relieved and the object cooled.  The object is heat treated by holding at a temperature in the range of 1,000-1,400°C without mechanical pressure for at least 5 minutes but for a time sufficient to provide a nucleating reaction in secondary phases formed as a result of hot pressing.  The heat treatment can take place either as an interruption of the cooling cycle or as a subsequent reheat cycle after cooling to room temperature.

Abstract: ABSTRACT OF THE DISCLOSURE:     The invention relates to a process for continuously manufacturing a composite band comprising a plastic sheet bonded to an aluminized pellicle, these two components consisting in separate bands before carrying out the process. The composite band issued of the process can be used for instance for insula-ting or padding. This band can also be used after cutting and thermoforming as pan or container for perishable products such as meat. The perishable product is put in the pan and both are covered with a plastic film to give a stocking and hygienic presentation. To carry out the process and to bond the basic plastic band (expanded polystyrene) to aluminized pellicle, these two sheets are introduced between calendering cylinders with interposing between the two sheets an intermediate film of plastic material at softening temperature to provide the adhe-sion. Of course, it is the non aluminized side of the pellicle which is in contact with the polystyrene basic band.

Abstract: ABSTRACT       A floating-caliper disc brake includes a non-rotating torque member which carries the caliper in fixed radial position relative to the disc via a pair of pins.          The torque member and caliper each have matching grooves which, when placed in registry, define a pair of apertures between the caliper and the arms of the torque member.  The pins are complementary in cross-section to the shape of these apertures so as to space apart the caliper and the torque member when the pins are inserted into the apertures. Brake torque is transferred from the caliper to the torque member solely through the pins which may be made of a material resistant to corrosion.  Sliding of the caliper along the pins provides for axial movement of the caliper relative to the torque member and brake rotor, but the caliper is other-wise restrained from movement in the radial and circumferential directions.

Abstract: ABSTRACT OF THE DISCLOSURE     A  prism polarizer comprising a pair of anisotropic crystal prisms which are faced to each other.  Each of said crystal prisms is composed of an crystal which has an optical characteristic that the difference between the square of the refractive index for extraordinary rays and the square of the refractive index for ordinary rays is larger than 1.  The angle of incidence of a beam upon the facing plane of said pair of prisms is equal to the Brewster angle for the refractive index for P-polarization rays. P-polarization rays are transmitted through said facing plane.  S-polarization rays are totally reflected at said facing plane.  Thereby, said incident beam is separated into two polarized beams.  Each of said pair of prisms is formed so that each polarized beam is totally reflected within each prism and that the separated outlet beams from said pair of prisms are parallel with each otter.

Abstract: ABSTRACT     An indicator system and device for visually monitoring ethylene oxide sterilization by color changes of the indicating composition of the system upon sufficient and properly conditioned exposure of the composition to ethylene oxide provides a controlled method for indicating the effective sterilization of articles by ethylene oxide.  The indicating composition of this invention undergoes color changes that are progressive with the conditions and periods of sterilization, such that a final and complete color change indicates the completion of an effective ethylene oxide sterilization.  The indicating composition comprises a leuco precursor of an aryl methane dye selected from the groups herein defined; and an acidic constituent.  Acidic organic compounds such as diphenolic acid (4,4-bis [4-hydroxyphenyl] pentanoic acid) are effective acid constituents because they enhance hue, develop color and stabilize the final color change.  The indicating composition is integrated into an indicator system and device further comprising a substrate or carrier and polymeric binder, any one or more of which may also provide wholly or in part the acidic constituent of the indicating composition.  The indicator device in the form of a coated ticket or tape is disposed with the articles to be sterilized within an ethylene oxide sterilization chamber.  Contact with ethylene oxide is maintained until a final color change, usually from a definite color to substantially colorless, occurs in the indicator, signifying the completion of an effective ethylene oxide sterilization of the articles.   28.

A clear water discharge outlet allows the discharge of clarified effluent from the vessel.  An inlet header allows the addition of an influent to be clarified into the vessel.  A vertically extending inner separation wall generally concentric with the vessel sidewall defines a moving bed area and an annulus area.  The annulus area provides a lower scour zone, a middle return zone and an uppermost reject zone.  The floc carrier is placed within the moving bed area and an aeration means is placed within the vessel annulus with the air being bubbled upwardly in the annulus scour zone where it is lifted thereinto and cleansed.  In the scour zone the media is scoured and expanded to clean the moving bed and individual floc carrier particles.  As the floc carrier particles rise, individual particles enter a return zone and are directed back to the moving bed, while concentrated detatched floc particles enter the reject area for disposal.
