Title: Process for the manufacture of n,n,n',n'- tetraacetylethylenediamine

Abstract: PROCESS FOR THE MANUFACTURE OF N,N,N',N'-TETRA-ACETYLETHYLENEDIAMINE     Abstract of the disclosure:     The invention provides an improved process for the manufacture of N,N,N',N'-tetraacetylethylenediamine by acetylation of N,N'-diacetylethylenediamine with acetic anhydride, by using these two starting components in a weight ratio of from 1:1 to 1:10, stopping the acetylation before attaining the reaction equilibrium between N,N'-di-acetylethylenediamine and N,N,N',N'-tetraacetylethylene-diamine, preferably after having attained a conversion rate of from 20 to 70 mol % of tetraacetylethylenediamine, relative to diacetylethylenediamine, purifying the reaction mixture in order to remove the dyeing impurities, and recycling to the acetylation the purified, incompletely reacted components. Purification may be carried out by vacuum distillation or be means of an adsorbent, for example bleaching earth or active charcoal. Optionally, from 0.01 to 0.3 part by weight of ketene per part by weight of diacetyl-ethylenediamine are added to the starting components.  The process may be carried out batchwise or continuously, and it gives a practically colorless product with high yield (more than 97 %).

Abstract: IMPROVED BICYCLE FORK     ABSTRACT     This improved bicycle fork is configured to prevent inadvertent separation of the wheel from the fork in the event that the axle retaining nuts become loose.  To accomplish this, the fork legs each terminate in a slotted, qenerally planar axle receiving member.  The bottom end of each such member, on at least one and preferably both sides of the slot, is bent slightly outwardly sufficient to catch and retain a loosened axle retaining nut, and thereby keep the wheel from becoming detached from the fork.  The lateral extent of each such bend advantageously exceeds the axial displacement of an axle retaining nut resultant from loosening of the nut by one full turn on the axle threads.

Abstract: TITLE:  GAME HAVING PATHWAY TRAVERSING A PLURALITY OF INDEPENDENT         OBJECT TRANSFER MECHANISMS                             ABSTRACT     A game of skill has a support housing on which there are located a plurality of independent object transfer mechanisms preferably no two which are identical.  The transfer mechanisms are aligned in a sequence such that a pathway includes a plurality of discontinuities along its length which divides it into a plurality of segments.  Each of the transfer mechanisms includes one segment of the pathway and some of the transfer mechanisms can also include more than one segment.  This creates a discontin-uity in the pathway between each of the transfer mechanisms as well as between each segment when more than one segment is found on one transfer mechanism.  Each of the transfer mechanisms includes a movable portion which is moved by the operator of the game via a control mechanism attached thereto.  By manipulating the control mechanisms a spherical object can be caused to travel across the pathway.  The object traverses the discontinuity in the pathway by a realignment of the segments achieved by moving the movable portion of the object transfer mechanisms.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a method of rotary piercing in seamless tube manufacturing under a rotary piercing process, such as Mannesmann mandrel mill process. Rotary piercing operation is carried out by employing a rotary piercing mill having a pair of cone-shaped main rolls adapted to cooperate with a plug for rotary piercing and disc rolls disposed in opposed relation between the pair of main rolls and adapted to press hollow shell on the surface thereof.  In this method of rotary piercing, the main rolls have feed and cross angles designed to meet certain conditions individually and in combination.  The method makes it possible to carry out rotary piercing of less hot workable and/or extremely hard-to work materials, that is, high-alloy steel billets, without surface tor-sional deformation and circumferential shear deformation.          Thus, it is possible to manufacture high quality tubes of high-alloy, steels free from outside seams and inside bore defects.
