Title: Dust and fume extn for cupolas - where air is sucked down open throat and carries fumes into side duct
IPC: C21B13/02
Filed: 1975-11-12
Abstract: In the elimination of dust and fumes from cupolas, the temp. of the combustion gases is lowered as they rise up the cupola by a current of air drawn through the open throat; the air flow is strong enough to stop the ascent of the gases and the resulting mixt. passes through a duct in the cupola wall below the throat to a filtration unit, and the purified gas-air mixt. is then discharged to atmos. The flow of air down the cupola throat is pref. greater than the flow of the combustion gases, and the pref. plant includes a suction fan drawing air through the duct. There is no need to use any device to close the throat and only a small amt. of water is required in the scrubber as the gases are primarily cooled by the flow of air.

Title: Nuclear reactor with molten salt combustible - has pressure chamber allowing safe rapid reactor emptying by pressure redn.
Inventor: VENTRE EDMOND
IPC: G21C1/22
Filed: 1976-03-18
Abstract: In the reactor, the combustible, generally plutonium fluoride or uranium fluoride, or a mixt. of fluorides of uranium or thorium, dissolved in fluorides of lithium 7 and of beryllium, is used as the heat transfer fluid in a prim. circuit. The circuit includes the reactor core, a pump and an exchanger in which heat is transferred to another molten salt which exchanges its heat in turn, in a sec. circuit incorporating a steam generator. Such a reactor can easily be shut down by emptying the prim. circuit into a chamber where the neutronic conditions necessary for the chain reaction, do not exist. The prim. circuit incorporates a vessel, a means of establishing and maintaining a press. of inert gas in the chamber, and a means of escape of the compressed gas. The chamber is arranged so that, when all the salt in the circuit is in it, the salt level is below that of the base of the core. The pipes connecting the vessel to the prim. circuit pass into the vessel to a level lower than the level of the molten salt. They allow molten salt to enter or leave the vessel according to the pressure of the inert gas which may be helium. The reaction to be stopped in complete safety, whereas in existing reactors, which are connected to a discharge receiver by a pipe in which there is a valve, need a positive action, including e.g. the opening of a valve maintained at a high temp. to prevent the salt solidifying.

Title: Multiple internal mandrels to chill extruded pipe - for cooling thick walled (polyolefin) pipes to a low stress state
IPC: B29C48/90
Filed: 1976-08-23
Abstract: The parent patent described a pipe extrusion die fitted with an extended mandrel for recirculating cooled air within the profile leaving the die. The downstream end of the mandrel was fitted with spring loaded wheels bearing against the inside of the pipe to keep the mandrel centralised. This addn. describes use of one or more additional internal mandrels linked by cables successively along the inside of the pipe. The additional mandrels have centering rollers at both ends. Used esp. for calibrating pipes made of semicrystalline materials, viz polypropylene or high density polyethylene, to produce pipes with relatively stress free walls by providing similar cooling rates inside and outside the mandrel. Use of multiple mandrels produces sufficient cooling for relatively thick walled pipes without the reduction in extrusion rate which would otherwise by necessary.

Title: Charging petroleum from offshore well to ship - using a flexible pipe extended by a caisson lifted at optimum rate by ship's hoist, avoiding damage
Inventor: HULSTIJN HENDRICK VAN
IPC: E21B17/01
Filed: 1977-02-18
Abstract: An appts. for collecting petroleum prods. from sub-marine wells incorporates a submerged structure, a caisson and a flexible pipe. The submerged structure is fixed and in communication with a well-head. The caisson is mobile and can be moved between a rest position on the submerged structure and a petroleum charging position at the surface of the water. The flexible pipe connects the submerged structure and the movable caisson. The caisson has a housing at its upper part in which are a float and a chain. The chain is coiled within the housing. Its ends are fixed to the housing and to the float respectively. The float is retained in the housing by a mechanism which allows the float to be liberated when it is actuated remotely. The length of the chain is about equal to the depth of immersion of the structure. When the float is liberated it rises to the surface taking the chain with it. The float has a hitch by which it can be picked up by a hoist on the ship. The hoist can then lift the mobile caisson carrying the end of the flexible pipe. Problems associated with existing equipments are avoided; these include rapid rising of the mobile caisson causing damage, and the fact that the flexible pipe hangs relatively slack and is subjected to the swell or to currents.
