Title: Integrated process using non-stoichiometric sulfides or oxides of potassium for making less active metals and hydrocarbons
Inventor: SWANSON ROLLAN
IPC: C01B15/043
Filed: 1984-01-09
Abstract: Potassium is produced from its non-stoichiometric oxide or sulfide and subsequently used to obtain less active metals and hydrocarbons. Potassium oxide or potassium sulphide is thermally decomposed substantially in the absence of water to produce potassium metal, and, respectively, potassium peroxide or potassium superoxide, and potassium disulphide, potassium metal being recovered from the other potassium products. A portion of the obtained potassium metal is reacted in the molten or vapor state with at least one oxide or sulphide of magnesium, copper, calcium, silver, lead, zinc, antimony, cadmium, iron, arsenic or mixtures thereof to displace the metal from the oxide or sulphide, the displaced less active metal being recovered from residual potassium or potassium compounds. A portion of the previously obtained potassium metal is reacted with water to form hydrogen, potassium oxide and potassium hydroxide, and some of the hydrogen obtained is used to prepare a hydrocarbon. The hydrocarbon can be prepared by reducing the hydrogen with the obtained potassium metal at a temperature between 250 DEG C and 300 DEG C to form potassium hydride which is reacted with carbon to form potassium acetylide which is contacted with water to synthesize acetylene and potassium hydroxide, the acetylene then being hydrogenated to ethene and ethane with hydrogen. Alternatively, the hydrocarbon can be prepared by using the hydrogen to hydrogenate carbon in the presence of a hydrogenation catalyst to form methane.

Title: The lamb handing device
Inventor: FROUDE ALEX
IPC: A01K15/00
Filed: 1987-02-27
Abstract: The lamb handling device is one which holds lambs absolutely stable for drenching, injecting, castrating and tailing. The device stands at an angle so the lambs slide down the roller base 1 of the chute very easily on their backs or on their sides, and as they slide, they slide down for the next operation to be carried out. They are loaded manually at the top end, and then the spring loaded control 14 holds them down very securely with holding bars 3. When the lambs are on their backs, their legs are free of any objects so they cannot lever themselves free. At the bottom of the device, the lamb is castrated and tailed, then pulled out easily and free to go. The device is fully adjustable and has telescopic legs 10 at each end, so it can be free standing or dropped onto existing sheep pens. <IMAGE>

Title: Resonant cavity devices
Inventor: WALKER CHRISTOPHER MARTIN
IPC: H01J23/20
Filed: 1987-05-13
Abstract: A magnetron of the co-axial type includes gas filled volumes 10 and 11 which are partly defined by glass walls 12, 13, 14 and 15. When the gas within the volumes 10 and 11 is in an electrically non-conductive state, the output frequency of the magnetron is determined by a cavity 5 having a geometry defined by the outer cylinder 4, anode cylinder 2 and end plates 6 and 7. When the gas within the outer part 10 is made electrically conductive by establishing a discharge within it, the geometry of the cavity 5 is effectively altered such that its bounding surfaces include walls 12 and 13. Thus tuning of the output radiation frequency may be effected.
