Title: Oxidative secondary rhodium recovery process
Inventor: CUSHMAN MICHAEL R
IPC: C07C53/12
Filed: 1990-11-26
Granted: 1994-01-11
Abstract: Disclosed is a process for recovering rhodium catalyst values from ''tars'' formed during the preparation of acetic anhydride by the rhodium catalyzed carbonylation of a mixture of methyl iodide and methyl acetate and/or dimethyl ether. The disclosed process provides a means for the recovery of rhodium values which normally are not extracted from the tars by treating a methyl iodide solution of such tars with certain oxidants.
Patent CA-2058891-C (CA)
Inventor: PETRUCCELLI DOM

Granted: 1996-06-04
Abstract: A golf club includes a straight shaft and a metallic member having a first end connected to the lower end of the shaft.  The other end of the metallic member is bent to define an obtuse angle with the first end.  In a preferred form, a flat metallic stiffener plate is welded or otherwise affixed to one side of the metallic member.  These portions are placed in a suitable mold into which polyurethane is admitted, and heat is differentially applied to or removed from the various surfaces of the mold in order that the polyurethane solidifies to form a substantially flat striking layer of dense integral-skin polyurethane juxtaposed against the stiffener plate remote from the metallic member, and a back cushion enclosing the stiffener plate and all of the metallic member.  The back cushion is thicker than the striking layer, and is of polyurethane less dense than that of the striking layer.  Preferably, the stiffener plate has marginal portions extending beyond the metallic member, and these marginal portions have apertures through which the polyurethane of the striking layer can integrally bond with the polyurethane of the back cushion.

Title: Improved process for the long term reduction of body fat stores, insulin resistance, hyperinsulinemia and hyperglycemia in vertebrates
Inventor: CINCOTTA ANTHONY H
IPC: A61K31/137
Filed: 1992-06-24
Granted: 1997-05-20
Abstract: A process for the long term modification and regulation of lipid and glucose metabolism generally to reduce obesity, in-sulin resistance, and hyperinsulinemia or hyperglycemia, or both (these being the hallmarks of noninsulin dependent, or Type II diabetes) - by administration to a vertebrate, animal or human, of a dopamine agonist and a prolactin stimulator. The dopamine agonist and prolactin stimulator are administered in daily dosages, respectively, at a time of day dependent on the normal circa-dian rhythm of fat and lean members of a similar species. Decreases in body fat deposits result by  treatment of a obese species on a daily timed sequence based on circadian rhythms of the peak prolactin, or peak prolactin and peak glucocorticosteroid, blood level established for lean insulin sensitive members of a similar species. The dopamine agonist is administered at the time of, or just after the time of peak plasma prolactin concentration found in lean animals of the same species and the prolactin stimulator is administered at a time just before the plasma prolactin ?hythm reaches its peak in lean animals. Insulin resistance, and hyper-insulinemia or hyperglycemia, or both, can also be contracted in humans on a long term basis by treatment or corresponding to that of the treatment for obesity. The short term daily injections reset hormonal timing in the neural centers of the brain to produce long term effects.

Ce corps (12) comporte également une série d'éléments de blocage (22) situés sous les clavettes (21) et allongés en position amorcée pour qu'ils puissent arrêter le corps s'engageant avec un anneau de blocage (R2) dans un train de tiges de fond.  La surface extérieure du mandrin interne (13, 14) présente le profil approprié et une disposition telle que, avec les éléments de blocage (22) qui s'engagent avec l'anneau de blocage, ce mandrin interne (13, 14) est en mesure de se déplacer par rapport au corps (12), de préférence après qu'un élément travaillant en cisaillement (15) situé entre ce corps et le mandrin s'est fissuré, pour déplacer les clavettes (21) radialement vers la position de mise en place où les clavettes (21) s'enclenchent avec une unité de réception (R1) du train de tiges, et après que cette mise en place a provoqué le déplacement radial vers l'intérieur de l'élément de blocage (22) sans qu'il subisse l'action de l'anneau de blocage (R2).  Toute charge axiale prend alors à peu près entièrement appui sur les clavettes (21).

Abstract: A method and apparatus for receiving discrete parts travelling at a first speed and applying the parts to a substrate web travelling at a second speed includes at least one rotatable transferring mechanism, a driving mechanism and at least one driven mechanism. The rotatable transferring mechanism is connected to an output shaft and moves along an orbital path through a receiving zone where the parts are received and an application zone where the parts are applied to the substrate web. The driving mechanism utilizes at least one rotatable noncircular drive gear connected to an input shaft to transmit rotational energy to the driven mechanism. The driven mechanism utilizes at least one rotatable noncircular driven gear connected to the output shaft or to a jackshaft to accept the rotational energy from the driving mechanism and transmit the energy to the transferring mechanism. The input shaft and output shaft or, in the alternative, jackshaft are offset such that the noncircular drive gear is configured to engage and rotate the noncircular driven gear which, in turn, rotates the rotatable transferring mechanism.
