Abstract: A stabilized binocular using a gimbaled and stabilized triple-reflecting compensator (such as in Humphrey U.S. Patent 3,475,073) having three reflecting surfaces for each binocular path is disclosed. Each of the binocular paths is in convergent light from an objective to and through gimbaled stabilizer assembly to a primary focus that is stabilized with respect to the case. The triple-reflecting surfaces disposed to reflect light in the manner corresponding to a single plane mirror at an effective mirroring plane with a displacement between the incident and reflected light beams. The compensator remains stabilized with respect to inertial space, while the instrument undergoes accidental angular motion. The reflecting property of the compensator brings the image back to the same place on the case despite the accidental angular motion. The displacing function of the compensator , enables the image to be displaced to a location where the image does not interfere with the incoming light path. This image is then processed by conventional field optics, including a zoom relay lens: Provision is made to adjustable compensate for displacement and resultant angular velocity, acceleration, and jerk. Resonance is naturally avoided as torquing forces are not applied where inertial centering of the compensator is sufficient.

Abstract: This invention provides novel compositions curable to resins and particularly provides oxygen permeable, inherently wettable optical devices useful as eye contact or intraocular lenses. The lenses are composed of a cured polysiloxane resin having an advancing water-in-air contact angle of no greater than 80° C. The polysiloxane resin is prepared from a catalyzed mixture of an acrylate-functional polysiloxane composition and an organosilicon cross-linking agent containing silicon hydride radicals. The acrylate-functional polysiloxane composition contains a sufficient amount of aliphatically unsaturated hydrocarbon radicals (e.g., vinyl radicals) other than acrylate-functional radicals to enable that composition to react on a mole to mole basis with the cross-linking agent to produce a cured polysiloxane resin. To provide the desired level of surface wettability, the acrylate-functional polysiloxane composition also contains an effective amount, typically from 7 to 30 mole percent of the total moles of siloxane units present in the cured polysiloxane resin, of H<sub>2</sub>C=CRCOOR'SiO<sub>l</sub>.<sub>5</sub> units to provide the aforementioned advancing water-in-air contact angles. The catalyzed mixture only contains a sufficient amount of cross-linking agent to react with the aliphatically unsaturated hydrocarbon radicals other than the acrylate-functional radicals and thus enables the unreacted acrylate-functional siloxane units to provide the desired wettability characteristics to the cured polysiloxane resin.

Abstract: The invention relates to a coin sorter apparatus for sorting a group of mixed coins (11) by denomination and automatically terminating the sorting process in response to a sensed operating parameter. Sorting is provided by a stationary disc (21) and a rotating disc (19) positioned sufficiently proximate to one another so that when the group of mixed coins (11) are dropped into the centre opening of the stationary disc (21), they are rotated by the rotating disc (19) and guided by the stationary disc (21) on a radially outward spiral sorting path which exits each denomination of the coins at discrete locations (49) along the periphery of the stationary means. As the coins (11) are sorted, a sensing means (69) provides signals indicating the presence of a predetermined condition. A bridge guide (71) and a diverter guide (72), which are part of the stationary disc (21), are responsive to the signals from the sensing means (69) to redirect the radially outward sorting path of the coins (11) to a radially inward path so as to terminate the sorting process. Optionally, a circuit responsive to the sensing means (69) controls the application of power to the motor (37) powering the rotating disc (19) of the sorter apparatus and cuts off that power, when the sorting process is terminated in order to prevent abrasion of the re-circulating coins or damage to the sorter apparatus.

Abstract: An improved method of making reconstituted tobacco using a dry-forming process. Fiberized tobacco stems and scrap are combined with tobacco material of a fine particle size. The resulting tobacco mixture is conveyed in an airstream and deposited on a moving foraminous surface. An adhesive is incorporated into or applied to the web bonding the tobacco particles into a coherent sheet, and the sheet is dried if necessary. The dried sheet may be divided into leaflets or shredded for further processing as reconstituted tobacco. In preferred embodiments, cellulose fibers are mixed with the tobacco particles prior to web formation to impart increased sheet strength. In a further embodiment tobacco fines are mixed with the adhesive and applied to the web in the adhesive composition. Results obtained by means of the present invention include cost savings particularly in terms , of reduced capital costs. Because the tobacco is used substantially in its natural state, the aroma and other desirable tobacco attributes are retained.

Abstract: The invention relates to a blank for a tool die, made of compound steel with a core of high speed steel and a surrounding ring of a different steel, said ring bringing about a prestress in the core. According to the invention, the prestress is due to the fact that the core consists of a high speed steel powder which has been compacted to full density, that the ring consists of a steel alloy, the residual austenite transformation to martensite and consequent volume increase of which is zero or considerably less than the residual austenite transformation to martensite of the high speed steel after the same heat treatment, and that the blank has been hardened and annealed to create in the core a compression stress as a result of the obstruction by the surrounding ring of the volume increase of the core. 
     The invention relates also to a method for manufacturing such blanks. A high speed steel powder is filled into a thick-walled pipe, said pipe consisting of a steel different from high speed steel. The pipe is closed and subjected to hot isostatic compaction causing the high speed steel powder to become compacted to full density, forming a compact core in the pipe, so that a compound material is obtained. The pipe is cut into several discs or pieces of suitable lengths. The material is hardened and annealed, the high speed steel core during heat treatment undergoing a greater residual austenite transformation into martensite than the surrounding ring, a compression stress thus being created in the core.
