Abstract: A method for the treatment of melt-grafted polypropylene to improve adhesive properties thereof is disclosed.  Molten grafted polypropylene, formed by melt grafting polypropylene with an alpha, beta unsaturated carboxylic acid or anhydride, is treated in melt processing apparatus with a minor amount of an aqueous solution of an alkaline material e.g. an aqueous solution of sodium hydroxide.  The thus treated grafted polypropylene is separated from the agueous solution and recovered e.g. in the form of pellets.  The melt-grafted polypropylene may be formed in the melt processing apparatus prior to treatment with the aqueous solution or polypropylene that has been grafted in a previous operation may be fed to the apparatus.  The treated polymer may be used in adhesive formulations.

Abstract: An IR suppressor produces a thin "ribbon" exhaust plume using a tapered exhaust manifold which has a plurality of discrete exhaust nozzles that are longitudinally aligned with the exhaust manifold.      Optionally, the nozzles extend within but are spaced apart from mixing ducts which are open to the ambient air at both ends. The mixing ducts mix ambient air with the exhaust plume. In another aspect of this invention, a single nozzle (which is longitudinally aligned with the manifold) is substituted for the plurality of discrete exhaust nozzles. In this aspect, the nozzle extends within but is spaced apart from a mixing duct which is open at both ends and has a curve sufficient to block a line of sight to the nozzle. A helicopter that has a rotatable IR suppressor so that the exhaust can be directed substantially parallel to the helicopter blades when the blades are not turning to protect them from exhaust heat is also disclosed.

Patent CA-2018893-A1 (CA)
IPC: B01F15/04
Filed: 1990-06-13
Abstract: A liquid chemical delivery system automatically delivers viscous chemicals to a number of destinations, such as a number of industrial clothes washers.   Several distinct chemicals are pumped, one at a time, into a manifold.  The chemical being pumped is mixed with water in the manifold and then transported through a distribution line to its specified destination.  By mixing the chemicals with water, viscous chemicals are diluted and delivered using a low pressure delivery system.  A single flow meter is used to calibrate  all  the  chemical  metering  pumps  and  to recalibrate  those  pumps  periodically,  thereby providing accurate chemical metering.  The manifold and distribution tube  are  automatically  flushed with water  after  every chemical  delivery  so  as  to  reduce  corrosion  and maintenance  costs.    In  addition,  potentially  reactive chemicals are kept separate from one another despite the use of only a single distribution line.  The system uses a proof-of-flow conductivity meter in the manifold to confirm the presence of each specified chemical in the manifold during  the  chemical  pumping  process.     Local proof-of-delivery  conductivity  meters  at  the  system's output ports are used to verify delivery of each chemical to the specified output port.

Title: Method of manufacturing oxide superconducting wire
IPC: H01L39/24
Filed: 1990-12-06
Abstract: In a method of manufacturing an oxide superconducting wire including steps of performing heat treatment and deformation processing in a state of filling up a metal sheath with powder of an oxide superconductor or raw material therefor, fine particles or gas adsorbed by the powder can be desorbed by heating the powder at least once preferably under decompression in a stage before final sintering of the powder.  It is possible to further withdraw the adsorbed fine particles or gas by heating the powder under decompression at least once before the same is covered with the sheath, covering the powder with the sheath, deforming the sheath and again heating the same under decompression, for example.  Thus, it is possible to prevent gas generation from the powder during heat treatment for further growing superconductive particles, thereby preventing the superconducting wire from inflation etc. caused by such gas generation.

Title: Method for determining oncogenic potential of a chemical compound
Inventor: BERNS ANTON J M
IPC: C12Q1/70
Filed: 1990-07-03
Abstract: ABSTRACT OF THE INVENTION Methods are provided for determining the oncogenic potential  of  chemical  compounds  which utilizes  a transgenic mouse  predisposed  to T-cell  lymphomas. The transgenic mouse expresses a pim- 1 oncogene and as a consequence is predisposed to the spontaneous onset of T-cell lymphomas.  The oncogenic potential of  a  chemical  compound  is  determined  by administering a known dose of the chemical compound of interest to a pim-1 transgenic  mouse.  Thereafter, the transgenic mouse is monitored to detect the onset of a T-cell lymphoma.   The time of onset of the T-cell  lymphoma  and  the  dosage  of  the  chemical compound  are  compared  to  either  the  onset  of spontaneous T-cell lymphomas in the pim-1 transgenic mouse or to the onset of a T-cell lymphoma in a pim-1 transgenic mouse which has been exposed to a known quantity of a carcinogenic agent.  This provides an indication of the oncogenic potential of the chemical compound.

Abstract: Abstract A single-piece, nonwelded multiple truss metal hanger connector is presented for connecting first and second supported wood members to a supporting wood member.  One of the supported members is oriented at 90° with respect to the supporting member and the other supported member is oriented at a skewed angle.  The connector has a flat seat for receiving the supported members and a pair of side flanges which extend perpendicularly upward from opposite side edges of the seat to form a U-shaped structure.  A pair of end flanges extend perpendicularly from the rear edges of the side flanges.  A pair of flange extensions extend outwardly from the forward edges of the side flanges at skewed angles. This construction permits either one of the supported members to be received by the hanger connector and oriented at 90° from the supporting member while the other one of the supported members is received by the connector and oriented at the skewed angle, thus eliminating the need for separate right hand and left hand devices.
