Title: Self extinguishing thermoplastic moulding material - using dehydropolymers of mono, di or tri substd. benzene
Inventor: GRUNDMANN RABEN DR
IPC: C08L65/00
Filed: 1975-06-10
Abstract: Self-extinguishing thermoplastics moulding material contain an organic bromine and 0.05-2 pref. 0.2-1 wt. % of a synergistic cpd. (synergist). The synergists are dehydropolymers of cpds. of mono, di or tri substd. benzene. The substits. are cycloaliphatic hydrocarbon residues with 5 and/or 6C. Pref. synergists are 1,1'-diphenylbicyclohexy or 1,1'-diphenylbicyclopenthyl. The dehydropolymers are prepd. by adding, in small amts. one part of a substd. benzene, mixed with an organic peroxide, to an equal amt. held at 120/200 degrees C. Decomposition prods. of the peroxide are simultaneously removed. After sepn. of unreacted substd. benzene, the dehydropolymer is obtd. The cpds. specified may be used to produce self-extinguishing moulded objects from thermoplastic moulding powders. They give comparable synergistic effects with known peroxides without the disadvantage of toxicity, explosiveness and limited life. e.g. 1,1'-diphenylbicyclohexyl used at 0.2-1 wt. % in polystyrene beads (plus 1% hexabromo cyclododecane). Foamed compsn. is self-extinguishing and results are comparable with those using known peroxides. In a pref. reaction cyclohexylbenzene is reacted with di-tertbutylperoxide. The crude dimers produced may be used after sepn. of unreacted monomer.

Title: Blood vessel prostheses of synthetic velours - by impregnation with a colloid and subsequent crosslinking
Inventor: BRAUN BERND DIPL CHEM DR MED
IPC: A61L27/14
Filed: 1976-01-15
Abstract: Blood vessel prostheses are made of synthetic fibre velours impervious to liqs. The prostheses are constructed in a double sided fine velours weave and their surface is treated by impregnation with an emulsion or soln. This emulsion/soln. contains weakly acid or neutral, colloidal organic cpds. The velours prosthesis treated in this way is evacuated in a desiccator and the emulsion/soln. is evaporated by means of a stream of hot air. Damaged blood vessels can be replaced, partic. after repeated insertion of cannulae in haemodialysis of patients with kidney failure. Bovine arteries have been used for this purpose, but are very expensive and tend to cause thrombosis. Synthetic fibre prostheses, even when woven with a double velours structure, are not free from objections. Attempts to render them impermeable by treatment with soluble proteins has resulted in the formation of fine flakes which act as seeding crystals and again result in thrombosis. These problems are overcome by use of the invention.

Title: Electrophotographic copying - using single component, electrically conducting toner particles with magnetisable core and resin carbon outer coating
Inventor: NAGAI KOJI
IPC: G03G15/16
Filed: 1976-02-26
Abstract: In the transfer of a toner powder image consisting of electrically conducting particles from a photo-receptor surface to a transfer material, in an electro photographic copier, the photoconducting layer of the photoreceptor surface is made electrically conducting by image-wise exposure to an adjacent light source. A potential is applied across the photoconducting layer in such a way that a charge is formed on the transfer material while a charge of opposite sign is induced on the layer. The charge on the photoconducting layer migrates onto the conducting toner particles. Coulomb forces are exerted on the charges on the toner particles by the charge on the transfer material and that in the photoconducting layer so that the toner particles are transferred electrostically to the transfer material. The electrically conducting toner powder pref. consists of fine particles of magnetisable material coated with a resin and carbon. The method enables a single component electrically conducting toner to be used in a practicable photocopier.
