Title: Improvements in or Relating to Machines driven by Reciprocating Electric Motors
Inventor: BARTHALON MAURICE
IPC: H02K33/02
Filed: 1966-09-08
Abstract: 1,152,209. Reciprocating electric motors. M. BARTHALON. 8 Sept., 1966 [24 Sept., 1965], No. 40181/66. Heading H2A. A reciprocating electric motor fed with D.C. impulses has an unwound armature moving transversely to the working flux and resiliently biased out of the working gap. The motor is especially suitable for a pump but has numerous other applications. As shown in Fig. 1, a singleacting pump piston 21 is operated by an armature 18 made up of plates of iron 22 spaced by insulation 22a to ensure saturation of the armature and linearity of performance. The armature slides between facings 61, 62 of P.T.F.E. In the form shown, the flux is generated by a single coil 6 fed from an interrupter 7 and rectifier 9 (see also Fig. 5, not shown). The device is regulated by a variable resistance. The armature is biased by spring 31 and returned by a vacuum space 16 and compression volume 16a. By using two air-gaps and one or two armatures, the motor may be made doubleacting. Various arrangements of thyratrons are described for generating the energizing impulses (Figs. 6, 7, 8, not shown). In the modification shown in Fig. 10, two coils 35 are employed and the armature laminations 53 are of graded thickness and aligned with the direction of motion. Cooling air is circulated through grooves 91 and a slot in the piston-rod 54. In a further modification (Figs. 12-15, not shown), the piston-rod acts through a hole in the stator yoke and the armature slides on guides. In yet another modification (Figs. 19, 20, not shown), the piston itself is long enough to act as support and guide for the armature which is secured to it and is also cylindrical.

Abstract: 998,022. Evaporators of the film-type. LUWA A.G. Nov. 13, 1961 [Nov. 14, 1960], No. 40525/61. Heading B1B. In the evaporator shown the liquid to be evaporated, supplied through pipe 7, is distributed as a film over the hot inner surface of tubular wall 5 by radial blades mounted on a rotary shaft 3, and the blade assembly comprises two sections, the upper section consisting of rigid blades 13b extending almost to wall 5 and the lower section consisting of blades 16 connected by rings 15 to supports 13a so that they move towards or away from the wall 5 when the speed of rotation is increased or decreased, respectively. The rotating blades 13b in the upper section continuously agitate and respread the film on the inner surface of wall 5 and promote evaporation. In the lower section of the evaporator the blades 16 are flung outwards by the rotation of the shaft so that they bear against wall-surface 5, spreading the liquid in a thinner film on the surface. In a modified construction, there is slight clearance between wall-surface 5 and the outer edges of blades 16 in their most radiallyextended position. The concentrated liquid is withdrawn from the evaporator via pipe 6, and the vapours pass out of the top of the evaporator via a separator 2. The evaporator casing is provided with two jackets 8 and 9, through which heating fluid or cooling fluid may be passed, thus producing a temperature gradient down the evaporator if desired. The fastening arrangement between the supports 13a and the blades 16 is such that the blades may be easily removed for cleaning.

Title: Process for the concentration of heavy water
IPC: C01B5/02
Filed: 1959-12-03
Abstract: <PICT:0867736/III/1> A process for the concentration of heavy water comprises extracting D from H2 from a water decomposer by catalytic exchange with NH3, bringing the thus D-enriched NH3 into isotopic exchange with H2O, decomposing the separated NH3 to N2 and H2, returning this gas mixture to the NH3-H2 exchange and returning the D-enriched water from the NH3-H2O exchange to the water decomposition. H2 from decomposition of H2O in electrolysis cascade 2 passes in countercurrent in 4 to NH3 withdrawn from the product of synthesis plant 6 to which the H2 is fed.  The NH3 is fed to exchanger 16, after removal of catalyst, e.g. potassamide, at 10 for return to the feed in 8, where it passes in countercurrent to H2O entering at 19.  The NH3 then passes to decomposer 18 whence N2 and H2 is returned through 22 to exchanger 4.  The enriched H2O from 16 is returned to cascade 2, where heavy water is also concentrated in the later stages.  Alternatively, a portion of the NH3 from 4 may be withdrawn, after catalyst removal, to separate decomposer 12 whence N2 and H2 is returned direct to exchanger 4.
