Abstract: GLAZING STRIP                        ABSTRACT A glazing strip for windows, curtain walls or the like comprises a resilient reinforcing member having an elastomeric material extruded over and covering the reinforcing member.  The strip has a retainer portion with a substantially flat glass engaging surface of the elastomeric material and an anchorage base which is insertable into a channel in a frame for a piece of window glass and is removable therefrom only by the application of deliberate force.  The retainer portion is laterally spaced from the anchorage base and the reinforcing member extends from a position adjacent the glass engaging surface at a location remote from the anchorage base and then into and along the anchorage base.  As a result, when a length of the strip is secured in the channel and in use, the glass engaging surface of the retainer portion will engage on only one side of the piece of window glass located in the frame.          The reinforcing member causes this glass engaging surface of the retainer portion to engage the surface of the glass along an edge region with a force of approximately 4-6 pounds weight per linear inch.  The arrangement enables the system to accommodate glass or other panels of varying types and thicknesses.

Abstract: 1              CHIN, G.Y. 11-1-10-2 Fe-Cr-Co MAGNETIC ALLOY PROCESSING           Abstract of the Disclosure A method is disclosed for making a metallic body having desirable magnetic properties.  The metallic body is made from an alloy which contains Fe, Cr, and Co and which may also contain one or several additional ferrite forming elements such as, e.g., Zr, Mo, V, NB, Ta, Ti, Al, Si, or W.  According to the disclosed method the alloy is cooled at a rate of at least 60 degrees C per hour from an initial temperature at which the alloy is in an essentially single phase alpha state to a second temperature which is in a vicinity of 600 degrees C.  Subsequently, the alloy is cooled at a second, slower rate to a third temperature which is in the vicinity of 525 degrees C.    The disclosed method allows for a relatively broad range of initial temperatures, is relatively insensitive to compositional variations of the alloy, and permits simple reclamation of suboptimally treated parts. As a consequence, the method is particularly suited for large scale industrial production of permanent magnets as may be used, e.g., in relays, ringers, and electro-acoustic transducers.

Abstract: ABSTRACT        This invention provides a method for manufacturing shaft seals comprising a sealing member rotating with the shaft and a stationary sealing member, the opposing planar surfaces of which form the seal.  In order to obtain shaft seals which are able to withstand the stresses occuring in actual use without permanent deformation of the sealing surfaces being caused, such as are caused by rapid variations in temperature, the sealing members are subjected to a heat treatment in manufacture to cause per-manent deformations.  The stresses caused by the heat treatment are to be at least as high as those stresses which will occur in actual use.  The sealing surfaces are precision finished e.g. by lapping, after the heat treatment.
