Abstract: ABSTRACT        HOMOGENEOUS, DUCTILE BRAZING FOILS       Brazing of metal parts employing a thin, homo-geneous, ductile, filler metal foil is disclosed.  The brazing foil, useful for brazing stainless steels, is not in excess of .0025 inch (3.81 x 10   cm) thick and has a composition consisting essentially of 0 to about 4 atom percent iron, 0 to about 21 atom percent chromium, 0 to about 19 atom percent boron, 0 to about 12 atom percent silicon, 0 to about 22 atom percent phosphorus and the balance nickel and incidental impurities.  In addition to containing the foregoing elements within the above-noted composition ranges, the composition must be such that the total of iron, chromium and nickel ranges from about 76 to 84 atom percent and the total of boron, silicon and phosphorus ranges from about 16 to 24 atom percent.  The ductile foil permits fabrication of preforms of complex shapes which do not require binders and/or fluxes necessary for brazing powders presently used to braze stainless steels and nickel base alloys.

Abstract: ABSTRACT OF THE DISCLOSURE         A clip driver for driving such a type of clip as having opposing holding webs the front edges of which are resiliently pressed to each other to form lips for clipping sheets of paper or the like.  The clip driver has a casing in which formed is a longitudinal guide way for guiding the clip, a clip driving member for driving the clip along the guide way and clip opening member with bifurcated inclined leg portions diverging toward the front end of the casing.  In use, the clip is driven forwardly by the driving member so that lugs extending laterally from the holding webs slide along the diverging surfaces to forcibly open the clip overcoming the resilient pressing force to permit the sheets of paper or the like to be placed between two holding webs of the clip.  As the clip is further driven forwardly, the lugs clear the guide surfaces of the clip opening member to allow the holding webs of the clip to be closed, thereby to clip the sheets of paper or the like.

Title: Apparatus for improving fibrous matter recovered from  refuse
Inventor: RAIMUND JETZER
IPC: B02C23/10
Filed: 1980-08-12
Granted: 1981-08-11
Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for recovering fibrous matter from refuse.  The refuse is comminuted prior to drying.          Major portion of heavy particle components is removed from the refuse after the comminution step, whereupon excessive size particles of the accepted stock are further comminuted by shear cutting so that the maximum size of any particle still contained in the stock is equal to or smaller than the greatest size of the particles containing fibrous matter.          The step of drying is either simultaneous with or follows the step of decomposing the substances that are readily biologically decomposable such as albumen, sugar, fat and starch.  The recovered fibrous matter is in the form of flakes, as opposed to the wool- or felt like appearance obtained in prior art, to facilitate subsequent porcessing of the recovered stock, e.g. gluing, and to improve properties such as mechanical strength of the products made from the recovered fibre stock.

Abstract: ABSTRACT OF THE DISCLOSURE     A road surface in which each road surface element has a cut-out portion which is delimited by means of section of a plate.  The cut-out portion is traversed by a bolt.  A locking piece which has two catches on its lower side is inserted into the chamber that is formed by the cut-out portions of two adja-cent elements and is then rotated so that the catches come to rest beneath the bolts.  The two elements are then locked together and forces are transmitted through the two locking portions and the catches to the bolt and thus from one element to the other.          The upper surface of the locking piece is level with the surface of the two elements.  This invention is applicable to the produc-tion of temporary road surfaces, for example, during road detours or for use in construction excavations.
