Title: Burner for liquid or gaseous fuels
Inventor: HUBER PETER DIPL ING
IPC: F23D14/34
Filed: 1988-12-10
Abstract: The invention relates to a burner for liquid or gaseous fuels, in which, inside an outlet pipe which tapers conically at its front end, a burner lance is arranged, which is displaceable in the axial direction of the outlet pipe and which is at its front end provided with a baffle plate which, according to its position with regard to the conically tapering outlet pipe end, defines the passage cross-section for the outlet of the combustion air which is introduced into the outlet pipe by a blower, and means for adjusting the blower pressure depending upon the axial position of the baffle plate being provided in the supply path of the combustion air. The invention envisages that the means for adjusting the blower pressure consist of an additional outlet on the pressure space formed between the housing and the baffle plate, the cross-section of which can be varied by displacing the baffle plate in such a manner that a constant blower pressure is developed automatically in any position of the baffle plate.

Title: Hydrogen nuclear fusion in opt. ionised molecule - by electron introduction between hydrogen nuclei
Inventor: PHILBERTH BERNHARD
IPC: G21B1/00
Filed: 1991-04-06

Title: Method for continuous production of ice cubes - uses hygroscopic properties of zeolite contained in cartridges
IPC: F25B35/04
Filed: 1991-04-18
Abstract: The method for the continuous production of ice cubes is carried out by a pump (7) connected through a valve (9) and a zeolite cartridge (1) to a vertically arranged heat pipe (3). The pump produces a partial vacuum inside the heat pipe, which causes some of the water in the heat pipe to evaporate. The low pressure steam thus formed is drawn through the zeolite cartridge where it is absorbed and then heated by the heat exchanger (6). The cartridge is one of a group mounted in a rotating drum which brings a second cartridge (2) into use as required. The low pressure steam is used to regenerate the previously used second cartridge. The evaporation of some of the water in the heat pipe causes the remaining water to freeze and the ice cube thus formed is expelled by the sliding rod (4) through the valve (78). USE/ADVANTAGE - Continuous production of ice cubes by a low energy method.
