Title: Disposal of used organic ion exchange compound - by embedding in mixture of cement and water absorbing compound
Inventor: CHRISTENSEN HANS
IPC: G21F9/30
Filed: 1975-11-03
Abstract: Used ord. ion exchange cpd. from the clearning cycle of a nuclear reactor installation is embedded in cement by (a) mixing the particles of the ion exchange cpd. with cement, (b) incorporating in the miext., before the cement solidifies a material (I) capable of blocking the penetration of water towards the particles of ion exchange cpd., and (c) allowing the cement in the mixt. to solidify in a container. Swelling of the particles of ion exchange cpd. is practically eliminated as a result of the presence of (I). This prevents weakening/disintegration of the concrete block. The block retains its initial structure for longer periods. (I) is dispersed or dissolved in water before adding to the mixt. (I) is pref. a linear polymer e.g. polyvinyl propionate a crosslinkable polymer, e.g. an epoxy resin, water-glass or another alkali metal silicate, a hydrolysable org. silicate or an org. ester of a higher fatty acid. 0.1-20 pts. wt.

Title: Inclined alignment of molecules in liquid crystals - by contact with surfaces of similar surface tension (NL 23.5.77)
Inventor: PORTE GREGOIRE
IPC: G02F1/1337
Filed: 1975-11-19
Abstract: The alignment may be extended to greater distances by use of a wall of special topography achieved by known methods e.g. rubbing, irradiation or inclined deposits. Surface tension of the wall is modified by coating with a suitable material, e.g. a satd. amino cpd. such as R-(CH2)n-R' where R is a hydrophic radical such as CH3, CH2Cl, CF3 or CCl3 and R' is a hydrophilic radical such as NH2, OH, or COOH. In liquid crystal indicator cells, esp. for alpha-numeric displays in clocks, calculators and measuring equipment, consisting of a liquid crystal film between two flat wall surfaces, esp. those of twisted nematic type. By slight inclination, e.g. 5-10 degrees, from the perpendicular, the tendency for molecules in some zones to tilt in the opposite direction to those in other zones when a field is applied, producing discontinuity lines between zones, is eliminated. Alignment over great distances from the wall, by using a cell in which at least one wall is treated to give the required surface tension, and the cell is filled from one end with the liquid crystal.

Title: Balanced pressure load hydraulic machine - has two sets of radial pistons with shoes slidable on casing having diametrally opposed eccentric portions
Inventor: MARTIN LOUIS EMILE
IPC: F04B49/12
Filed: 1975-12-31
Abstract: The cylindrical casing (1) houses a rotor (2) with a double row of pistons (15, 16). The eccentricity of the bore (13) is diametrically opposite to the eccentricity of the bore (14). This has the effect that each piston (15) is always in the same phase as a piston (16) which is diametrically opposite, and therefore the pressure loads are always balanced. The pressures in the inlet ports (32, 33) are always in balance as are the pressures in the outlet ports (34, 35). In addition, the distances (M) to the centre line of the ports are so chosen that the resultant of all the moments due to port pressures and piston pressures is equal to zero.
