Title: Mixing head for mixing at least two components which form a plastic
IPC: B29B7/76
Filed: 1986-06-07
Abstract: The invention relates to a mixing head for the mixing of at least two components forming a synthetic material, the mixing head comprising a mixing chamber and a discharging channel which is guided in a guide channel having a symmetrical cross-section. The mixing head is operable to provide mechanical self-cleaning of the discharging channel and mixing chamber by a discharging piston. An intensive mixing of the reaction components is achieved along with stabilization of the liquid mixture of the components after the mixture has left the mixing chamber in that a throttle member provided at the downstream end of the mixing chamber, is movable in and out of the cross-section of the channel and forms in its throttling position, a throttle slit which is flared towards the outlet opening of the discharging channel like a diffusor.

Title: Compositions for the administration of hyaluronic acid to mammals
IPC: A61P25/04
Filed: 1987-04-22
Abstract: The present disclosure is concerned with the discovery that hyaluronic acid, an agent well known to reduce the sequelae of trauma in mammalian joint tissue when applied directly to the traumatized tissue, will be carried to such traumatized tissue by the mammal's natural processes if applied at a site remote from the traumatized tissue. Thus, hyaluronic acid, in any therapeutically acceptable form, can be administered by the typical remote routes including intravenous, intramuscular, subcutaneous and topical. This makes the utilization of hyaluronic acid much more convenient and attractive. For instance the treatment of arthritis in horse or human joints with hyaluronic acid no longer requires more difficult intra articular injections.
Patent EP-0261378-A3 (EP)
Title: Heat resistant binders
IPC: D06N5/00
Filed: 1987-08-13
Abstract: Heat resistant binders for flexible nonwoven mats may be prepared using an emulsion polymer comprising 100 parts by weight of acrylate or styrene/acrylate monomers, 3 to 6 parts of a blocked, N-methylol containing comonomer, 0 to 3 parts of water soluble non-blocked N-methylol containing comonomer and 0 to 5 parts of a multifunctional comonomer. The use of the blocked N-methylol containing comonomer permits the incorporation into the latex binders of higher levels of N-methylol functionality with consequent increase in heat resistance. As such, the binders are useful in the formation of heat resistant flexible mats for use in roofing, flooring and filtering materials.

Patent EP-0315999-A3 (EP)
Title: Method for reproducible mould filling with moulding materials
IPC: B29C45/77
Filed: 1988-11-11
Abstract: In the production of mouldings from crosslinking moulding materials, in particular by the injection-moulding process, reproducible filling of the mould is problematical. Overfilling, with the consequence of flash formation, or underfilling, with the consequence that rejects are produced, frequently take place. In the case of the method proposed, the degree of mould filling is controlled with the aid of the pressures measured in the mould. The method makes use of the fact that crosslinking moulding materials are generally introduced into a mould which is of a higher temperature than the moulding material. After filling the mould, the moulding material is heated up in order to start the crosslinking reactions. The heating up causes a volume expansion. If the mould is completely filled, the expansion is prevented and a pressure increase occurs. If the mould is underfilled, expansion completely or partially takes place. The pressure increase is then less or there is no pressure increase. With suitable boundary conditions, these pressure signals characterise the mould filling level. The method provides mould filling control which acts from shot to shot. The reference variable for the control loop is the mould cavity pressure. The correcting variable for the control is, in the case of injection moulding, the metering stroke. In the case of other processes, the metering weight or the metering volume may be used. <IMAGE>
