Title: Process for the preparation of phosphoric acid and calcium sulphate anhydrite as well as phosphoric acid and calcium sulphate anhydrite obtained by this process
IPC: C01B25/228
Filed: 1981-07-14
Abstract: Phosphate rock is digested with H<sub>2</sub>SO<sub>4</sub> into phosphoric acid and gypsum, the latter is separated off, washed and converted into anhydrite. After this first wash the gypsum is divided into a minor portion of fine crystals, which is discharded, and into a major portion of coarse crystals, which is subjected to a second wash, thereafter recrystallized into anhydrite by means of concentrated H<sub>Z</sub>SO<sub>4</sub>, the anhydrite being separated and washed and the recrystallization liquor returned to the digestion zone. The washing liquor obtained from the anhydrite wash is used for the second gypsum wash, the washing liquor obtained from this second wash is, together with water, used for the first gypsum wash, whereas the washing liquor obtained in this first wash is returned to the digestion zone. In this way practically all gypsum formed can be converted into anhydrite, while substantially all water can be functionally used without dilution of the H<sub>3</sub>PO<sub>4</sub>-product.

Title: The production of ion exchange resins, the resins so produced and ion exchange processes using them
IPC: B01J39/20
Filed: 1981-05-18
Abstract: In a process for producing ion exchange resin capable of hydraulic segregation into discrete zones of resin having different ion exchange functionalities, the resins are produced by differently functionalizing fractions of a single batch or lot of precursor copolymer which have been classified on the basis of differing hydraulic densities of the different sized particles. Ion exchange processes comprise contacting a fluid containing exchangeable ions with resin produced by this process and deionisation by this technique is of particular interest.

Abstract: The invention relates to a navigation radar system in 
which a secondary radar responder provides a reply in respon­
se to an interrogation radar signal received from a primary ra­
dar transmitter. The frequency of the received radar signal is 
monitored by the responder and the response is transmitted at 
a frequency which is off-set from that of the interrogation si­
gnal so that the response can be received by the primary radar 
and distinguished from primary radar echoes.

Title: Motor generator operating according to the reluctance principle
IPC: H02K29/06
Filed: 1983-09-08
Abstract: For an internal combustion engine, such as a motor vehicle engine, operating on the principle of "flywheel utilization" an electromagnetic unit can be used both as a starter motor and as a generator. In addition, this unit is easily adaptable to the given flywheel dimensions and it involves as low a cost as possible for the controlling semiconductor components and for the exciter power. The invention proposes, among other things: (a) a stator with several independent sector stators arranged at tangential distance from each other, with pairs of toothed sector stator elements arranged at an axial distance a one behind the other and each having a radially projecting pole shank connected together by a flux return yoke; (b) a rotor with two rows of teeth mutually offset "tooth on gap" on the circumference of the clutch flywheel; and (c) use of MOS transistors for the electrical commutating of motor operation, the inverse diodes of which are utilized as rectifier elements in generator operation.

IPC: C12P13/04
Filed: 1985-08-15
Abstract: Amino acids can be easily prepared by reducing unsatu­
rated hydantoins to the corresponding saturated hydantoins 
by hydrogenating the unsaturated hydantoin using either 
Raney Nickel catalyst in the presence of more than a 
stoichiometric amount of caustic or by using zinc and 
hydrochloric acid followed by hydrolyzing the resultant 
composition with at least 3 molar equivalents of an alkali 
metal hydroxide to produce a racemate of an alpha amino 
acid. The amino acid in suitable derivative form can then be 
resolved particularly using a two-phase solvent system. The 
residual isomer of the amino acid remaining after the 
resolution process can then be racemized using either 
pyridoxal-5-phosphate or an aliphatic acid in combination 
with an aldehyde or a ketone. By these procedures, it is 
possible to obtain high yields of amino acids.

Abstract: A process for distillation of two materials of differing 
boiling points particularly propane, ethane or carbon dioxide 
from natural gas is described in which the conventional dis­
tillation tower is divided into a first tower (102) at higher 
pressure than a conventional tower and a second tower (104) 
at lower pressure. Liquid drawn from the first is expanded 
to the lower pressure through two or more stages (111, 112) 
with cool extracted (65,62) at each stage and used to cool 
(65,62) gas (51) withdrawn from the top of the first tower to 
keep the top tray at a required temperature. Gas (19) with­
drawn from the second tower (104) is compressed and cooled 
for return to the first tower as a reflux. The use of the cool 
from the expanded liquid and the use of the two towers 
provides an improved thermo-dynamic efficiency and avoids 
the use of costly turbo-expanders.

outer end portion of the lever, and the first snap-fitting 
means may comprise detent projections on the body adja­
cent the valve lever when in its sealing position, the 
projections being resiliently deformed momentarily upon

portion of the spigot, the first snap-fitting means may be a 
radially inwardly extending portion of the opening wall, so 
that these annular portions interfere when a spigot is moved 
into the dispensing opening and are resiliently deformed, 
then engaged to retain the spigot in sealing position. The 
wall defining the dispensing opening and the spigot exterior 
configuration may be tapered radially inwardly in the 
direction of the insertion of the spigot for force-fitting sealing
