Title: A process for preparing non-extruded stabilized olefin polymers
Inventor: CASELLI GIANCARLO
IPC: C08J3/12
Filed: 1990-08-01
Abstract: Disclosed is a process for preparing nonextruded stabilized olefin particles. The process includes the step of polymerizing an olefin monomer or olefin monomers in the presence of a Ziegler-Natta catalyst, thus obtaining olefin polymer particles having a spheroidal shape, and the step of depositing a stabilizer mixture on the polymer particles. The stabilizer mixture is a molten mixture or a mixture in which at least the stabilizer (A) is in the liquid state, without containing any solvent, and comprising the following stabilizers (percent by weight with respect to the weight of the polymer particles): (A) from 0.020 to 0.15% of one or more organic phosphates or phosphonites or mixtures thereof which are liquid at room temperature or have a melting point below 100° C;. (B) from 0.025% to 0.2% of one or more phenolic antioxidants with melting points from 45° to 130° C; and, optionally, one or more of the following additional components: (C) from 0.05% to 0.5% of one or more thioethers or organic polysulfides or mixtures thereof; (D) from 0.10 to 1.0% of one or more light stabilizers which are liquid at room temperature or have a melting point below 150° C, selected from the group consisting of hindered amine light stabilizers, benzophenone and benzotriazole derivatives; (E) one or more diluents selected from the group consisting of paraffins and cycloparaffins which are liquid at room temperature or have a melting point below 110° C, epoxidized soy bean or linseed oil, silicone oils and olefin oligomers, in an amount not greater than 0.3%.

Abstract: PRESPOT DETECTION METHOD         APPARATUS IN AN ANALYZER                      Abstract A method and apparatus are described for detecting an erroneous pre-spotting of a test element in an analyzer.  The invention utilizes a wetness detector and calculates the second derivative of the R-C time decay curve produced by such a detector, to determine if a sudden increase in a slope exceeds more than a threshold value for two consecutive points.  The threshold value is picked so as to exceed sudden increases that can be created by noise in the system.

Title: Measurement of optical attenuation along the length of bent optical fibers
Inventor: REDFORD GARY
IPC: G01M11/00
Filed: 1990-08-28
Abstract: MEASUREMENT OF OPTICAL ATTENUATION ALONG TEE LENGTH OF BENT OPTICAL FIBERS              ABSTRACT OF THE DISCLOSURE        Optical  signal attenuation due to bends in an optical  fiber  (12) is measured by bending a segment of   the   optical  fiber  (12)  into  the  shape  of interest,  measuring the attenuation in that segment, propagating  the  bent region along the length of the optical  fiber  (12),  and repeating the measurement. The  attenuation as a function of the position of the bent  segment  along  the length of the optical fiber (12)  is  thereby  measured.    The  approach  is  of particular   interest   in  determining  peel  point bending  loses  along the length of the optical fiber (12) to identify areas of signal transmission.

Title: Child resistant closure
Inventor: KUSZ MAXIMILLIAN
IPC: B65D50/04
Filed: 1991-01-23
Abstract: A child resistant closure comprising outer and inner nested closure members each of which has a base wall on a peripheral skirt with sets of lugs on the inner surface of the outer closure member and on the outer surface of the inner closure member which are adapted to be engaged when the members are moved axially toward one another. The outer surface of the base wall of the inner closure member is provided with a plurality of ramps and depressions and the inner surface of the base wall of the outer closure member is formed with a plurality of integral spring fingers. When the closure is applied, the springs fingers engage the depressions and orient the outer closure member and inner closure member preventing inadvertent engagement of the lugs by any top load. When the outer closure member is rotated relative to the inner closure member without bringing the lugs thereon into engagement, the spring fingers slip over the ramps allowing the outer closure member to rotate with respect to the inner closure member.

Title: Method of bending a laminate having a thermoplastic core layer and metal sheets on each side
IPC: B21D5/04
Filed: 1991-09-30
Abstract: Bending a laminate having a thermo-plastic core layer and metal sheets adjoining the core layer on both sides, is performed by heating the laminate and then bending it.  To allow bends of small radius to be made, heating causes softening of at least one of the boundary regions of the core layer adjoining the metal sheets, while a central region of the core layer remains unsoftened.  The heat may be by inductive heating of one or both metal sheets.

Title: Purification process for methyl acetate
Inventor: SCATES MARK O
IPC: C07C69/14
Filed: 1991-11-14
Abstract: ABSTRACT         Esters such as methyl acetate which contain carbonyl impurities including aldehydes are purified by adding to the esters an amino compound which reacts with the carbonyls to form water soluble nitrogenous derivatives, separating an organic ester phase from an aqueous derivative phase, and distilling the ester phase to further remove heavier impurities.  The formation of nitrile from the nitrogenous derivative is minimized by adding water to the distillation column or washing the aqueous bottoms from distillation with water to further remove the derivatives from any ester contained in the bottoms.  The organic phase recovered from the bottoms can be recycled to the distillation to recover ester.
