Title: Plastics component repair - uses prepd. plugs of fibre layers to fill shaped recess at faulty or damaged zone for resin bonding into place
Inventor: EYERER PETER PROF DR
IPC: B29C73/30
Filed: 1990-06-21
Abstract: To repair a component (10) of plastics, and esp. cpd. fibre materials, a recess (14) is formed in the component by removing material at the damaged area (11) or the fault. Fibre mattings (25), woven sections or the like which match the shape and size of the recess (14) are assembled in layers (24) to pack it. The packing layers are either impregnated with a resin directly before insertion or the recess is filled with a resin. The shape and size of the recess (14) to be formed are one of a few standard dimensions. The packing layers (24) are prepd. in advance according to standard sizes, and held in readiness so that they are available to fit into a recess formed to cut out a faulty or damaged area. ADVANTAGE - The repair is effected simply, rapidly and cheaply, with material that bonds in with the body of the component and has the same mechanical properties as the component material.

Abstract: The prepn. of non-infectious blood plasma comprises treating the plasma with nonionic surfactants, adding biologically compatible lipids prior to sepn. of the lipid phase, separating the lipid phase and removing the nonionic surfactant by solid phase extn. on hydrophobic materials. Deep frozen blood plasma is gently thawed in a water bath at 20-30 deg.C.. The pH of the plasma is set to 7.0-7.4. The nonionic surfactant is tri-N-butylphosphate (TNBP) and/or Triton X-100, esp. in aq. mixts. in ratio TNBP:Triton X-100:water 0.5-2:0.5-2:2-4. The lipid phase is sepd. by centrifuging and removed by filtration on hydrophobic filter material. The amt. of lipids added is 10% (v/v%). The solid phase extn. is carried out on materials suitable for reversed phase chromatography, esp. using octadecyl derivatised materials. After solid phase extn. the plasma is sterile filtered, opt. after adjusting the pH to 7.0-7.4. Alternatively the plasma is then freeze dried and lypholised opt. in the presence of conventional auxiliaries. The hydrophobic filter material is micronised.
