Abstract: SPEED NUT                        ABSTRACT A threaded nut assembly that can be positioned quickly on a threaded bolt and which selectively engages the threads thereof. The assembly includes both a nut casing and a jam nut means consisting of jam nut segments that include arcuate faces wherein thread sections are formed. The nut casing interior includes an inclined surface that supports, in sliding engagement, the threaded jam nut segments that move thereon to contact edges of arcuate faces thereof forming a hole or opening therethrough, the threaded sections forming a continuous thread. The inclined surface and the jam nut means face in contact therewith are angled at the same angle from the vertical, which angle is preferably the thread angle. The movement of the jam nut means therefor expands or contracts the distance between the thread sections to engage and disengage from the threads of the bolt over the entire thread length and a spring biasing is provided to urge the segments toward one another. In the engaged position, the nut may be tightened into locking position by a conventional rotational motion.

Abstract: Abstract Shaping glass sheets by lifting a heat-softened glass sheet on a lower mold having an upwardly facing surface defining a given sharpness of bend and transferring said glass sheet by suction to an upper vacuum mold having a downwardly facing shaping surface defining a lesser sharpness of bend.  Optionally, a ring-like member defining a sharpness of bend that may be equal to, less severe, or more severe than that defined by the upper vacuum mold moves between the molds when the latter are separated to impose a shape in the glass sheet that is correlated with the shape defined by the ring-like member.  The ring-like member is used to support the glass sheet for rapid cooling if the glass sheet is to be tempered.  Only the ring-like member need be changed when a change in production pattern is made.

Abstract: A B S T R A C T      Intra-aortic balloon apparatus is disclosed including a single chamber balloon sealably attached to the end of a catheter for non-surgical insertion into the aorta through the skin as by the standard Seldinger technique.  In the preferred embodiment, the extreme end of the balloon is fixedly attached to one end of a separate substantially circumferen-tially rigid but longitudinally flexible tube open at both ends and disposed within and extending the length of the catheter.  The opposite end of the tube remote from the balloon is fixedly attached to means for effecting rotation of the tube within the catheter and thereby result in con-trolled sequential wrapping and unwrapping of the balloon about the tube.  In use, the balloon is pumped in conventional manner via the catheter and access through the tube is provided to the interior of the aorta at the extreme end of the balloon.          When the end portion of the tube within the balloon is formed of a relatively flacid or flexible material, it is advantageous to use a stylet or wire member for insertion in and along the length of the tube to prevent bending of the flexible portion when the balloon is wrapped around the tube.  The tube also permits use of a guide wire to facilitate passing the balloon through the aorta to its desired location.

Abstract: Abstract of the Disclosure An improved method of making binderless zeolite sieve extrudates.  After extruding a mixture containing about 40-60% zeolites with the remainder being a metakaolin clay that has mixed with it about 90-120% of the stoichiometric amount of sodium hydroxide to convert the clay to a zeolite, the extruded particles are allowed to dry age under dry, bulk conditions in a container during which time autogeneous heat develops and most of the clay is converted to the zeolite.  A further heat treatment in a dilute caustic aqueous solution may be used to insure complete crystallization with subsequent washing and calcination to produce an adsorbent product.

Abstract: ABSTRACT OF THE DISCLOSURE:         The present invention is concerned with foils made of partially acetalised polyvinyl alcohol, especially foils formed of polyvinyl butyral.  These foils contain, as platicizers, esters of aroma-tic carboxylic acids whose ester components can possess up to 10 C-atoms, alone, or as mix-tures, or mixtures formed of these esters with esters formed of aliphatic carboxylic acids and glycols, chiefly di-, tri-or tetraethyleneglycol.  These esters may be worked into the partially acetalised polyvinyl alcohol foils in higher pro-portions than the hitherto known plasticizers, without being exuded or influencing disadvantageously other important properties of the foils.  They have the additional advantage that the laminated panes produceable therefrom possess a lower capacity for water uptake than hitherto known laminated glasses.

Abstract: Abstract of the Disclosure The invention relates to a process for the production of an aqueous bituminous preparation and the preparation itself.  The process is character-ized in that bitumen melt is dispersed in an aqueous medium containing aluminium hydroxide gel prepared from a water-soluble aluminium salt and an alkaline earth metal oxide or hydroxide or magnesium oxide and/or hydroxide or from mixtures thereof.   The preparation is useful in the construction industry e.g. for the production of asphalt with filler materials and roof plates or covering slabs with carrier materials.  Since the preparation is aqueous it is safer to use than bitumen itself or organic solvent based bitumen and further, the preparation can be used and stored in the cold state.
