Abstract: ABSTRACT OF THE DISCLOSURE         A process for producing an olefin polymer by polymerizing an olefin with a catalyst system compris-ing an organoaluminum compound and a supported catalyst component prepared by using as the carrier a solid product obtained by the reaction of an organomagnesium compound with an aluminum halide compound and/or a silicon halide compound, by heating a liquid ether complex of titanium trichloride in the presence of said carrier, and further reacting the resulting titanium trichloride-containing solid product with titanium tetrachloride.  By this process, the olefin polymer having a broad molecular weight distribution suitable for flow molding or extrusion molding is produced.

Abstract: TIRE RETREADING SYSTEM Abstract of the Disclosure Tire casings are retreaded with precured tread strips in a heated pressure vessel provided with pressure connections which effect simultaneous inflation of the tires and pressurization of the vessel while maintaining tire pressure above vessel pressure.  Subsequently a pressure relief system permits the tires to exhaust faster than the vessel.  Each tire is prepared for retreading by applying a bonding medium between the tire periphery and the retread strip and wrapping the resulting assembly with a fluid impervious flexible cover. Tread stabilization rings, wick material and non-stick polymer film may be inserted between the tread strip and the cover. The improvement according to the invention also comprises interposing between the tread strip and the cover, a thin, flexible perforated film of synthetic polymeric material which causes the flexible cover to slide against the surface of the tread strip and to thereby penetrate into the tread grooves so as to conform with the tread profile.  A further improvement comprises interposing between the tread strip and the cover, at a location of the connection between the exhaust conduit and the cover, a pad of porous fabric which is stretchable in two directions to thereby aid in releasing air from the space.

Abstract: FLUID MOTOR CONTROL SYSTEM                      ABSTRACT     A fluid motor control system is designed to ensure that automatic changes of motor displacement, which are initiated by occurrence of a predetermined operational condition in the system, result in a change of motor speed of the desired magnitude.  Flow adjust-ment elements respond to a displacement increase by reducing the flow of working fluid available to the motor or motors and respond to a motor displacement reduction by increasing the available flow.  In one specific form, the system controls a pair of right and left side vehicle drive motors and provides for auto-matic reduction of the fluid flow supplied to the motors on increase of the motor displacements to reduce travel speed during turning.

Abstract: ABSTRACT    A method and apparatus for resuscitating, administering anesthesia to, or administering respiratory care to a patient is shown which allows greater rebreathing of mixed expired gases thus improving humidification and heat retention in the inspired gases.  The inhalation breathing circuit may include two concentric, non-kinking, corrugated tubes, one visually apparent within the other, for handling both fresh gases and mixed expired gases of the patient or the inhalation breathing circuit may consist of a spiralled inflow tube contained within the wall of the larger exhalation corregated tube.  An adjustable exhaust pressure valve maintains a predetermined pressure range for the gas being delivered to-and-fro between a breathing bag and the patient.  Expired gases vent through an anesthesia bacterial filter or may be scavenged to prevent environmental pollution.  Suctioning of the patient may be performed without interrupting the fresh gas flow or ventilation to the patient.

Abstract: A SIMPLIFIED PROCEDURE FOR THE ISOLATION OF ANALYTICALLY PURE VICINE [2,6-diamino-4,5-dihydroxypyrimidine 5-(B-D glucopyranoside)] AND CONVICINE [2,4,5-trihydroxy-6-amino-pyrimidine 5-(B-D glycopyranoside)] ABSTRACT OF THE DISCLOSURE          Conventional methods of preparing vicine and convicine utilize relatively slow, expensive and ineffi-cient procedures and considerable difficulty is encounter-ed in obtaining pure concentrations of either chemical. The present method overcomes disadvantages inherent in con-ventional procedures and produces an exceptionally high quality product.  A crude extract of vincine and convicine is first prepared by using a protein-rich concentration of faba beans or the like which is extracted with a basic aqueous-organic solvent which is then concentrated by evaporation.  The pH is then adjusted so that crystalliza-tion of the vicine and convicine takes place and the crystals are harvested by centrifugation or the like thus producing a crude vicine-convicine isolate.  The vicine can then be extracted from the isolate by adjustment of pH due to the fact that the pH has a differential effect on the solubility of the vicine and convicine.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to a rubber skim stock and a product containing the skim stock having improved adhesion between a brassed or zinc coated metal member and contiguous rubber skim stock.  The invention lies in the discovery that improved rubber-to-metal adhesion, and adhesion retention, can be obtained by adding to an otherwise conventional rubber skim stock composition appropriate amounts of cobalt propionate.          In the practice of this invention, cobalt propionate is mixed into a rubber skim stock composition, which composition is brought into contiguous relationship with a brassed or zinc coated metal member in the unvulcanized composition followed by vulcanization to yield the end product.
