Title: Ion exchange 5-cycle water softener - with grouped manual control assembly
IPC: B01J49/00
Filed: 1973-09-25
Abstract: Water softener uses ion exchange resins, which can be regenerated with sodium chloride, and is of the 5-phase type. It consits of a bottle, usually of fibreglass, which can be left exposed or enclosed in a casing to harmonise with neighbouring household machines. The pipes and the various controls are grouped together in a compact assembly around the stopper which closes the neck of the bottle. The assembly can either be left exposed or enclosed in a block. The hard water is poured over the resins through a strainer, and the water passing through the resins reaches another strainer. When the resin is exhausted, after about 15 days service, the resin is de-compacted by passing water in the reverse direction. The bottle is then emptied by siphoning. Regeneration is effected by pouring salt through the bottle neck and introducing water to dissolve the salt. After 30-45 mins. the brine is drained off and the resin given a slow or a rapid rinse. The process then starts all over again. Manual control is easy; the tap assembly is provided with a chart showing which taps are to be opened and which closed for each of the five phases.

Title: Method of classifying objects - uses code word elements and weightings to select objects
IPC: G06K21/04
Filed: 1974-03-15
Abstract: Each object is assigned to at least one of m classes. In correspondence to each object m codes c are formed from a reference R identifiable by one of the elements of a code word at p positions permitting separate or additive combinations smaller than or equal to the sums of their respective weights. A multiplication coefficient k is assigned to each class, such that k, s is at least equal to the number of objects which are assigned to it.

Title: Heat exchanger connector for fast neutron reactor - gives better distribution of liq. and better thermal insulation
Inventor: BERNIOLLES JEAN-MARIE
IPC: G21C1/03
Filed: 1976-03-29
Abstract: After simple crushing, the rock sample is pyrolysed in an atmosphere of inert gas (pref. argon, helium or nitrogen) at 400-1000 degrees C; from the furnace, the pyrolysis prods. are carried on the same inert gas to a chromatographic appts., where their benzene content is measured.
