Inventor: READER PHILLIPS JOHN GERALD
IPC: B22F1/102
Filed: 1968-11-23
Abstract: Manufacturing of a powder from which a porous structure, e.g. an electrode, can be made, by mixing the electrode material in powder form with a dispersion of polymeric material in a suitable liquid opt. with a fixing agent, heating to drive off the liquid, and pressing and heating the resulting powder. The fixing agent, usually an inorganic salt, is used to control the pore size of the final product. Polymeric material is pref. acrylic and the liquid in which it is dispersed must be compatible with the electrode material, e.g. nickel chloride may be used with Ni electrode powder. The powder may also be polypropylene. Method avoids bubbling in porous product. Problems of hot- or cold-forming in previous methods are dispelled.

Title: Magnesium ammonium phosphate
Inventor: LOEBLICH DR KARL-RICHARD
IPC: C05B7/00
Filed: 1969-01-21
Abstract: Magnesium ammonium phosphate (MAP)is produced from hydrated magnesium sulphate, phosphoric acid or a conc. soln. of a very soluble salt of phosphoric acid and, if necessary, ammonia. The exit materials or their solns. are reacted at 0-60 degrees C pref. 25-30 degrees C with a satd. soln. of ammonium sulphate (AS). This soln. is heated enough, pref. 55-65 degrees C, for AS developing with the reaction, to be able to be removed from the heated soln, and for the exit material or solns. of them, to be inserted, only with such a water content that exceeds the bonding power of the MAP. The heat content of the warmed soln. increases with the heat of reaction of the final loss of evaporation sufficiently to allow the initial cold of the AS satd. mother liquor to be reachieved by water withdrawal. Either an excess of this mother liquor results which is useful for other purposes or AS results as a solid by cooling down as described, or both can occur. The MAP hydrate is led away from the AS soln. which is then cooled in a evaporation loss apparatus by water evaporation. The low water product is granulated by addition of water at a suitable temp.

Title: Skimmer rake for power-station ponds
Inventor: STEINER HANS
IPC: E02B8/02
Filed: 1969-02-07
Abstract: Skimmer rake for power station ponds, clarifying basins, etc employs a cable hoisted rake carriage on which the rake swings between stops limiting the raised work position and the lowered, open position, the pivot axis of the rake is outside its centre of gravity so that gravity drives the rake continuously from its open position right through an intermediate position towards the active position. The cable is hinged to the rake so that in this intermediate position the hinge point is below the horizontal plane drawn through the pivot axis and the pivot axis bisects the axis of the cable. A stop limits the bottom setting of the carriage.

Title: Ammonium phosphate from raw phosphate - by digesting with sulphuric acid and ammonium monosulphate and extracting with hot moth
IPC: C01B25/28
Filed: 1970-10-22
Abstract: Raw phosphate is digested in conventional appts. with sufficient H2SO4 and NH4HSO4 to give calcium sulphate and monoammonium phosphate, the latter being dissolved out with hot mother liquors originating from the process, crystallised out after evaporative cooling, and dried. In an alternative procedure, the hot monoammonium phosphate soln. is adjusted to 57-73% H2O, ammonized, and cooled to 15-20 degrees C., to precipitate mono-, di- or tri-ammonium phosphate, depending on the amount of NH3 used for the ammonization. The use of NH4HSO4 in the digestion reduces the amt. of H2SO4 required and enables the digestion and reaction of resulting H3PO4 to give monoammonium phosphate to be carried out simultaneously, resulting also in savings in NH3 requirements. The ammonium phosphate products are of use in fertilisers.

Title: Nuclear fuel rod spacer grating system - using rotation of asymmetrical rods for locking against fixed stud spacers
Inventor: LETTAU HANS
IPC: G21C3/334
Filed: 1972-06-08
Abstract: Vertical fueld rods of the elements used in the core are maintained at fixed alignment and spacing by horizontal gratings one above the other in the normal way, these having eg hexagonal or square meshes. Instead of sprung or resilient etc. Iodgements for the rods being placed within the meshes, the limbs at each side, or on sufficient sides for a minimum of three point support, carry rigid abutments with concave faces of the true circular curvature of the sheaths. In the simplest form however the sheath is distorted symmetrically eg by flattening so that the rod can be inserted with the flats aligned with the abutments and then locked in position radially by twisting through 60 or 45 degrees respectively. As a refinement, additional recess and protrusion patterns may be made in the sheath in planes above and below the level of the grating so that when inserted the recessed sections are aligned with the abutments and on turning as above the protrusions are aligned to give axial anchorage.

Title: Refuse compactor with moving refuse container - has flexible axle for reducing pressure on wheel bearing on compacting
Inventor: HERMEIER WERNER
IPC: B30B9/30
Filed: 1973-11-02
Abstract: The refuse press has a removable refuse container with rollers for pulling out from the press housing. Flexible axle of the rollers of the container deflects on compacting in order to relieve load on the rollers during the compacting process. This arrangement ensures that the refuse container carrying a heavy load is at all times resting on rollers and rails and it can be readily removed. The refuse compactor container rests on two rollers. The axle connecting the rear wheels acts as a spring. When vertical compacting load is applied then the axle is deflected and the base of the container comes into contact with the floor of the refuse compactor housing. This arrangement protects the rolls and their bearings.

Title: Electroforming thick components, esp. copper - while deposit is shot-blasted with a dispersion hardening material
Inventor: WITTICH WILLIBALD DIPL CHEM DR
IPC: C25D5/22
Filed: 1973-11-23
Abstract: In this electroforming process, the metal component is made by depositing a layer on a conducting substrate and, during deposition, the layer is continuously or periodically shot blasted with sufficient force to produce plastic deformation and residual compressive stresses in the component. The component may be periodically withdrawn from the bath and host blasted or partly immersed in the electroforming bath and rotated, the exposed portion being shot blasted. The bath may contain fine-grained particles in suspension, which exert a mild grinding action on the layer, and/or a dispersion-hardening material, 0.1-10 mu in size; whiskers can be used and the component can be heat-treated to form an alloy with the dispersion hardener. Used for mfr. of Cu parts. e.g. propellant nozzles for combustion chambers in rocket engines. Thick components of complex shape are obtained with a fine homogeneous structure, and good mechanical properties at high temp., without the use of addn. agents in the bath which decompose at high service temp. and impari the strength of the component.
