Abstract: OPTICAL FIBER POSITION SENSOR                 ABSTRACT OF THE DISCLOSURE           An optical fiber position sensor includes an optical fiber cable wound in the shape of a single layer, tightly wound coil, the coil being secured to a first member.  A second member, which is linearly movable with respect to the first member, has fixed thereto an LED which is aimed at the coil such that radiation being emitted from the LED is injected approximately tangentially into the coil. Radiation being transmitted through the coil is attenuated as a function of the distance that it travels therethrough and as a result, radiation exiting the coil through the terminations is representative of the location of  the movable member with respect to the fixed member.

Abstract: STOVE CONSTRUCTION FOR ACHIEVING COMPLETE FUEL COMBUSTION     PETER KILHAM     Abstract of the Disclosure A stove apparatus which is designed to achieve relatively complete combustion of solid fuel such as wood or coal.  A combustion chamber is defined by a connected wall housing and includes a primary flue opening at an upper rear portion thereof.  Primary combustion air enters into the forward portion of the combustion chamber and the resultant combustion gases are deflected from normally passing to the chimney via the primary exit flue by means of a downwardly extending baffle which creates an increased temperature exit zone adjacent thereto.  A device for introducing secondary combustion directly into said exit zone is provided so as to insure more complete combustion and reduce the amount of tars, i.e., creosote, produced in the combustion process.  In addition, an unique device for regulating the amount and direction of primary combustion air enterinq the combustion chamber is provided.

Abstract: Abstract of Disclosure This Invention relates to the composite fiber incorporating the neutron-shielding properties consisting of a fiber-forming polymer as the core-component essentially containing certain compounds capable of shielding the neutrons and the other fiber-forming polymer as the sheath-component capable of bonding said core-component, while this Invention also relates to the method of manufacturing said composite fiber embodied by this Invention.     The composite fibers embodied by this Invention are not only capable of containing a large amount of the neutron-shielding compounds in the fiber themselves, but also capable of being made into knits and sewn fabrics by means of conventional spinning, knitting and sewing machines, and yet, these fabrics made from said composite fibers can be completely free from drop-out of even the slightest amount of the neutron-shielding compounds during either fabrication procedures or use and also free from any problem that may potentially be caused by atmospheric diffusion of the secondary radioactive material generated by the nuclear reaction.     The neutron-shielding fabrics thus embodied will protect the surgical operators as well as the patients from any of the irradiat-ed neutrons during surgical operations such as in removing cerebral tumor and also protect the operators of the nuclear-reactor from potential hazard of exposure to the neutron rays.

Abstract: Abstract of the Disclosure In a process of fragmenting and segregating metallic components fabricated from different aluminum alloys, a method of removing tramp impurities therefrom is provided.  The method comprises the steps of providing a feedstock comprised of the metallic components having mixed therewith tramp impurities, the alloys having different incipient melting temperatures.  The feedstock is heated to effect incipient melting of the component having the lowest incipient melting temperature and is then agitated sufficiently to cause the component having the lowest incipient melting temperature to fragment.  The agitation also causes the fragmented component to scour tramp impurities from the unfragmented feedstock.  The fragmented components and tramp impurities are segregated from the unfragmented feedstock and fragmented components are separated from the tramp impurities.

Abstract: MOTEUR ENERGETIQUE II Précis On sait que l'on peut habituellement classer les moteurs en deux catégories selon qu'ils utilisent des pistons à course rotative ou encore des pistons à course rectiligne. Alors que les premiers possèdent un torque supérieur,leur force explosive est considérablement limitée puisque les gaz n'y sont pas compressés. D'un autre côté,les moteurs à piston dont la course est rectiligne,bien que comportant une compression supérieure,ne comportent en revanche que peu de torque. La présente solution technique visera donc à produire un type de moteur qui pourra s'avérer une synthèse équilibrée entre un torque et une compression intéressantes.
