Abstract: Abstract of the Disclosure A rolled core is formed by winding a thin body of an amorphous magnetic alloy having positive magnetostriction characteristics so that, of the two surfaces the surface of smaller surface coarseness faces inward.  This rolled core is improved in iron loss over a rolled core obtained by winding the thin body so that the surface of greater surface coarseness faces inward.  Breakage of the thin body tends to occur less frequently when it is wound so that the surface faces inward.

Abstract: ABSTRACT OF THE DISCLOSURE       A dot matrix printer has arranged in the bottom of a cup-shaped cylindrical casing thereof a solid disc form of axially uniformly magnetized permanent magnet having a single pair of poles each formed on one or the other of its opposite end faces over the whole region thereof.  A circular plate of magnetically permeable material is fixedly mounted on the magnet and a set of coiled posts are fixedly fitted  to the plate.   The casing is formed on its outer periphery with cooling fins for dissipation of heat generated therein during printing operation.  The magnet and the plate thereon, identical in outer diameter, are radially spaced an appropriate slight distance from the inner wall surface of the casing to form a bypass circuit for the flux of the magnet.  Arranged in the open top of the casing is a spring-charge type print hammer assembly which includes a radial array of resilient tongues (hammers) and print wires secured thereto by flat armature plates fixed to the respective tongues.  The print head is particularly suited for high-speed printing operation with low power requirements and, owing primarily to the extremely simplified form of magnet used, is of reduced fabrication cost.  The armature plates, in cooperation with a yoke plate slotted to receive the plates serve to compensate for any possible increase in reluctance of the main magnetic circuit and increase the kinetic energy of the tongues or print hammers when released.

Abstract: INFRARED SENSITIVE PHOTOCONDUCTORS           Morris Feinleib Mary Jane Wegener ABSTRACT       A photoconductor material having high sensitivity to infrared light is provided therefore making it suitable for use in laser printers.  The photoconductor of this invention has a dark decay of approximately 40 volts/second, thereby enhancing the use of this invention with infrared laser printers as compared to prior art infrared sensitive photoconductors.   The photoconductor of this invention comprises cadmium sulfide (CdS), cadmium selenide (CdSe), cadmium carbonate (CdCO3) and cadmium oxide (CdO) in a binder,  and preferably also includes a small amount of copper dopant.  The photoconductor of this invention is prepared by adding ammonia to a suspension of cadmium sulfide/cadmium carbonate in water and then adding hydrogen selenide to this suspended solution.  The ammonia provides a means for retaining the selenide in the solution for an increased period, thus allowing the selenide to remain in the solution for a time sufficient to allow the selenide to react with the small amount of cadmium ion in solution at any time, thereby providing a suspension of intimately mixed CdSCdSeCdCO3 crystallites.

Abstract: Retaining Pin Assembly for Earthworking Tool Abstract A retaining pin assembly for securing a replaceable earthworking tool to a support member includes a spring type pin and a coacting sleeve.  The pin assembly is insertable through generally aligned openings in the tool and support member and functions to lock the tool to the support member and to force an end portion of the tool into contacting relationship with shoulders of the support member.   Earth-working apparatus, such as impact rockbreakers and rippers, generally include a replaceable tool mounted on a shank or support member.  Unless the tool is forceably held in contact-ing relationship with the support member, the retaining pin, tool, and support member are subject to damage. The retaining pin assembly of the present invention secures the tool and support member in contacting relationship and maintains a continuous locking force between the tool and the supporting member.
