EP 0 395 066 A2, 26.04.1990. "Apparatus for cold nuclear fusion". Prepared by a German representative (patent lawyer?), this incredibly badly written patent application claims a number of "preferred embodiments" for cold fusion. One is electrolysis at a cathode of an alloy capable of occluding hydrogen isotopes, such as Ti, Zr, and the like, in an electrolyte containing a compound of hydrogen isotope and oxygen such as heavy water including alkali metal ions such as Li+, K+ and the like. "Tritiums", "noutrons" may be produced by making use of "lithiums" and by the "tonnel" effect. There is a list of example alloys for use as cathode, all having larger hydrogen occlusion ability than "Pb" and the like. An example shows that at the end of an electrolysis, 5 times the starting concentration of T is found, proving that cold fusion had taken place. Also, 500 neutrons of 2.45 MeV were detected or 10 times the background. In the second preferred embodiment, some amorphous alloys are used, not having "a crystal lattice rule of a long period", meaning (presumably) no long-range order. Some of these appear to have a rather high hydrogen uptake. Crumbling was never observed and again, excess tritiums are seen. The third embodiment uses a large (7 mm diameter) spherical cathode. In this way, the collision probability for deuterons is enhanced in the centre of the electrode and in this way, the nuclear fusion reaction was caused easily and an enormous energy was obtained (I am quoting). Two to ten times the background neutron count was detected in an example. In another example, two spherical alloy samples were charged with D2 gas, and then a high-frequency discharge passed between them. Neutrons at 1000 times the background was observed; using pure H2, the neutron flux was the same as the background. Temperature cycling was also tried, and neutrons detected.
Hagelstein PL; Int. Pat. Appl. WO 90/13129, 1-Nov-90. "Fusion apparatus". "Fusion apparatuses for coupling fusible material to a quantized mode in coherent fusion are provided. Method for optimization of reactor operation, control of the coherent fusion reaction and extraction of usable energy generated are provided". Some of the means of doing this are: containing the fusible material (deuterium) in an electrically conductive radially symmetric vessel and initiating fusion through coupling to plasmon modes or by radially polarizing insulating crystals, or by lining the vessel with radially disposed rod-like projections electrically connected in series with an oscillator and in series with a computer controlled variable load for extracting the energy; acoustic excitation or excitement by alpha particles or cosmic rays. The inventor's theory is given (twice), p.48 shows a letter to Florence and Sam and there are 138 claims. —————————————————————– Hasegawa M, Hosono N; Eur. Pat. Appl. EP 414,399, 27-Feb-91. Cited in Chem. Abstr. 114:255493 (1991). "Process for storing hydrogen, and apparatus for cold nuclear fusion and method for generating heat energy, using the process". "A process for storing H comprises placing a H storing member in a H gas atm. and generating a discharge in the H gas atm., thereby occluding the H in the H storing member.

Hora H, Miley GH; Ger. Offenl. DE 3810806 A1, 11.10.1990 (in German). "Verfahren und Anordnung zu Kernverschmelzungsreaktionen bei tiefen Temperaturen" (Method and apparatus for nuclear fusion reactions at low temperatures). Professors Hora and Miley (editor of Fusion Technology) write that the electrolytic charging of Pd or Ti with deuterium leads to surface contamination. This is avoided by charging with deuterium gas under pressure, which is one of their inventions here laid bare. The 9 claims widen this concept to include any metallic element in "the eighth group of the periodic table" being exposed to H2, D2 or T2 gas, temperature control during such a process, absorption of neutrons, alpha or beta emission, the admixture of such isotopes as (11)B, (6)Li and (7)Li to the metals, attainment of high hydrogen isotope concentration in the metal, the use of electric discharge towards this end, the use of high-surface forms of the metals or mixtures thereof, control of the metal hydrides' compressibility and finally, the use of these processes for initiating an explosive nuclear fission [sic] reaction. Since this is an Offenlegungsschrift and not (yet) a full patent, no details are given of how all this is implemented. —————————————————————– Hosono N; Jpn.

This patent sets out to solve several problems with "conventional" cold fusion apparati and thereby give us reliable cold fusion. These problems are: a) the use of "solusion", allowing little chance for cold fusion; b) creation of deuterons in the same place as that in which they are to fuse; c) poisoning of the Pd, leading to no more deuteride; d) much deuterium is wasted as D2 gas and not used for fusion. The invention produces a dense plasma (10-1000 times as dense as plasma formed by high frequency fields) from gaseous D2, and then accelerates the deuterons towards the Pd target by means of a voltage field. The plasma is generated by resonance of microwave and magnetism. The gas is >= 98% pure D2 plus a little H2 and He. There are further details of heat exchange for the heat produced, prevention of overheating of the magnets etc.

EP 0 392 324, 3-Apr-1990. "Electrochemical nuclear fusion method". Yamazaki (working for the Semiconductor Energy Laboratory Co., Japan) starts by summarising what is wrong with the way Jones+(89) carry out electrolytic cold fusion. The use of atmospheric pressure reduces the probability of cold fusion; the reaction tends to occur at a localised section of the electrode from the rise in temperature at that point; poisoning of the cathode leads to side reactions and product decomposition, and the deuterium ends up in the atmosphere, so the amount used for fusion is small; says Y. The invention describes a pressurised cell, with the evolved gases (which are kept separate) providing the pressure. A heat exchanger removes the excess heat, thus keeping the cell temperature down. The cathode is either Pd or Ti, the electrolyte being a mixture not unlike that of Jones+(89). Neutrons are measured by a detector; nuclear fusion "is obviously accelerated when the reaction at the cathode is implemented under high pressure". Up to 200 atm can be used. The neutrons released can cause subsequent nuclear fusion by breeding, so there is some danger of an atomic explosion, which can be prevented by controlling the extent of electrolysis. This is done by pulsing the current, to a level not exceeding the critical nuclear fusion value. Two example experiments showed that the neutron flux is proportional to the pressure, and can be controlled by the duty ratio of the pulsed current. Excess heat was also observed.
