Abstract: ABSTRACT OF THE DISCLOSURE      A folding chair having a pair of spaced parallel arms with a U-shaped frame secured therebetween, multiple seat cushion assemblies are pivotally secured to one another and the U-shaped frame.  A movable support member is positioned within the area defined by the arms and can be moved relative thereto.  The cushion assemblies are secured to the movable support member extending the cushion assemblies into horizontal end to end alignment as the support member is moved from between the arms.  This invention is distinguishable from others by reason of the arrangement of the U-shaped frame between the arms and the form and attachment of the cushion assemblies thereto.

Abstract: LOCK OPEN MECHANISM FOR SUBSURFACE SAFETY VALVE            Abstract of the Disclosure A subsurface safety valve for use in wells, preferably adapted for placement in a tubing string, having a lock open mechanism for temporarily maintaining the safety valve in the open to flow position.  The safety valve includes a closure device, such as a rotatable ball, located in the flow passage of the valve and is opened and closed by a biased operator tube.  The operator tube is movable in response to hydraulic fluid conducted to the safety valve operating on a piston carried on the operator tube.  A shiftable sleeve and collet is positioned above the operator tube and has a profile for re-ceiving a shifting tool.  When shifted, the collet and sleeve act on the operator tube to hold the valve in the open to flow position.  The collet engages a recess on the bore wall of the safety valve upon shifting, and the sleeve moves behind the engaged collet head to prevent unlocking.  The safety valve can be returned to operation by shifting the sleeve and collet to their original, normal position.

Abstract: L'invention concerne un procédé de fabrication de laminés en acier présentant une bonne soudabilité, une haute limite d'élasticité, ainsi qu'une résilience à très basses températures. Le procédé selon l'invention est caractérisé en ce que l'on soumet un acier titrant au maximum 0,16% C, 2,0% Mn et 0,03% Al au minimum à un laminage, puis soumet les laminés obtenus à un traitement thermique pour obtenir un grain très fin; ce traitement thermique consiste à réchauffer les laminés en 2ème chaude jusqu'à température d'austénitisation, à les maintenir à cette température pendant un temps suffisamment court pour empêcher le grossissement du grain et à procéder à un refroidissement énergique en surface. L'invention s'applique notamment à la fabrication de ronds à béton.

Abstract: GAl-3P-6517 WORKPIECE EJECTOR SYSTEM        FOR PRESSES Abstract of the Disclosure An improved workpiece ejecting system for presses in-cludes an ejector piston hydraulically driven in response to reciprocation of the press slide in a manner whereby the motion of displacement of the ejector piston corresponds to the motion of displacement of the press slide during the stroke thereof, and the extent of displacement and velocity of the ejector piston are proportional to the corresponding charac-teristics of the slide.  Ejector piston displacement is achieved by the flow of hydraulic fluid to and from the ejector piston chamber during reciprocation of the press slide through its total stroke.  Ejector pins of various lengths are selectively associated with the press tooling and ejector piston to pro-vide for varying the length of the workpiece ejecting stroke. Displacement of the ejector piston in the ejecting direction can be stopped prior to the slide reaching the end of its return stroke to provide a dwell in elector pin displacement to facilitate workpiece feeding and removal with respect to the press tooling.

Abstract: ABSTRACT OF THE DISCLOSURE   A process is disclosed by which thermoplastic elastomers may be utilized to prepare melt-formable composite rocket propellants.  The thermoplastic elastomer is dissolved in a volatile organic solvent, the other propellant ingredients are mixed in, and the volatile organic solvent is eva-porated.  The dried propellant is melt-formed to final shape by molding or extruding above the melting point of the elastomer.  An example of a usable thermoplastic elastomer is a block copolymer comprised of about 5 to about 20 weight percent styrene and of about 80 to 95 weight percent diene.          The formed grain can be reclaimed by melting or dissolution in an organic solvent for reuse of the propellant ingre-dients.

Abstract: ABSTRACT OF THE DISCLOSURE      In connection with an arrangement in an ice machine which comprises a series of substantially parallel vertically arranged ice freezing elements which during the ice freezing phase are supplied with water, and which are provided with conduits for transport of freezing medium or thawing medium, as well as vessels arranged below the ice freezing elements and adapted for collecting surplus water, and an ice crusher box for crushing and delivery of finished produced ice, there is between the bottom of the ice freezing elements and the collecting vessels for water and the ice crusher box provided a pivotable baffle means which effectively serves to separate ice and water during the various steps of the ice producing process. During the ice freezing phase the baffle means adopts an inclined position which covers the ice collecting vessel, so as to pass the surplus water to the water collecting vessels via a stationary inclined guiding plate having a water pervious field. During the ice harvesting phase when the water supply is shut off, the pivotable baffle means will under the weight of the ice crop be allowed to swing from its inclined basic position to an approximately vertical position and permit the ice flakes to be passed to the ice crusher box, whereafter the pivotable baffle means subsequent to the finished harvesting phase will retain its original inclined position covering the ice crusher box.

Abstract: ABSTRACT     A joint for connecting together two or three framework members is disclosed.  In one form there are two framework members which intersect.  Inside one of the members there are two arms which protrude from one end of that member.  The pro-truding portion of each arm has a groove therein and a tooth beyond the groove.  The grooves and teeth face away from one another. The other member has an internal cavity with a slot-like entrance to the cavity bounded by lips.  When the protruding ends of the arms are close to one another, the arms can be inserted through the slot-like entrance so that the lips enter the grooves and the teeth hook behind the lips.   A screw passes through one of the arms and this can be tightened to that it bears on the other of the arms to force them apart and into engagement with the lips.  A resilient clip holds the other ends of the arms together and simultaneously urges said one ends apart whereby, before the screw is tightened, there is sufficient friction to hold the arms in position with respect to the lips.          The arms can be substantially symmetrical in form with a tooth and groove at each end so that when the resilient clip is removed, the arms can be used for connecting two parallel members.
