Title: Manufacture of polymers.
IPC: C08G63/80
Filed: 1967-09-08
Abstract: A polymer is prepared by conducting a polymerization reaction in a liquid melt phase, uniformly dispersing throughout the molten polymer an inert gas or vapour, and maintaining the dispersion through the polymer while cooling it to form a friable solid polymer, comminuting the friable solid polymer and continuing the polymerization in the solid phase. The inert gas is any gas which is not ordinarily reactive with the polymer under conventional polymer melt process conditions. This includes non-reactive materials that are gaseous under ambient conditions (1 atmosphere and 25 C.), e.g. nitrogen, carbon dioxide, helium, argon, some hydrocarbons, and some halogenated hydrocarbons (having boiling points below the solidification temperature or melting point of the polymeric melts) as well as the non-reactive vapour of materials (such as certain of the halogenated hydrocarbons and hydrocarbons) that are not necessarily gaseous under ambient conditions but which become gaseous at elevated temperatures and/or reduced pressures. Mixtures of gases may be used. In the examples polyethylene terephthalate is made using dimethyl terephthalate, ethylene glycol, zinc acetate dihydrate and antimony trioxide.

Patent ES-401271-A1 (ES)
Title: Thermal expansion valve with rapid pressure equalizer
IPC: F16K17/19
Filed: 1972-03-28
Abstract: The thermostatic expansion valve is provided with an internal by-pass capable of providing rapid equalization of the pressure between the condenser and evaporator when the compressor shuts down. The valve controlling the refrigerant flow has an internal cavity in communication with the condenser pressure and a by-pass port in communication with the evaporator. The valve, urged towards the closed position by a spring, is actuated by the diaphragm through push pins. The push pins normally close the by-pass port, either by the lower end of one or more of the push pins cooperating with a seat located at the by-pass port outlet or a valve means (e.g. a flanged collar which guides the valve) interposed the push pins and the by-pass port. With the valve in the closed position, the push pin(s) or valve means can be lifted off the by-pass port by condenser pressure in the cavity, as forces across the diaphragm equalize after shutdown of the compressor. The system pressure is then rapidly equalized through the by-pass port.
