Microwave animal stunning equipment for slaughter - has electromagnetic radiation units in semicircle around head of animal

Animals for slaughter are stunned using micro-waves. A number of electromagnetic radiation units are mounted in a semicircle round the head of the animal. These can be arranged to travel with the animal at the same speed over a set distance, and to act on the animal's brain. After travelling over the set distance, they can be arranged to return at high speed for the next operation. The stunning station can also protect against radiation and dampen noise, and there can be metal curtains at the ends. ADVANTAGE - Does not depend on operator's skill for full effect.

CONTINUOUS PROCESS OF SMELTING METALLIC LEAD DIRECTLY FROM LEAD- AND SULFUR-CONTAINING MATERIALS

ABSTRACT OF THE DISCLOSURE : The present invention relates to a continuous Process of Smelting Metallic Lead Directly From Lead- and Sulfur-containing Materials. A slag phase and lead phase are conducted in a countercurrent to each other in an elongated horizontal reactor, in which a gas atmosphere is conducted in a countercurrent to the slag phase. To maintain the molten bath at a constant temperature and to permit an operation at the lowest possible temperatures whereas an undercooling of the melt is prevented, the temperature of the molten bath in the reducing zone is maintained constant by a controlled supply of additional heat, the temperature of the molten bath in the oxidizing zone is maintained constant by a control of the ratio of oxidizable sulfur to oxygen in such a manner that in case of a temperature rise the ratio of sulfur to oxygen is increased in order to decrease the lead oxide content of the slag and in case of a temperature drop of the ratio of sulfur to oxygen is decreased in order to increase the lead oxide content of the slag and the increase and decrease of the ratio of sulfur to oxygen are controlled with an allowance in advance for the fact that the heat content of the gases entering the oxidizing zone from the reducing zone is changed with the lead oxide content of the slag.

BLOWING HIGH-OXYGEN GASES INTO A MOLTEN BATH

PROCESS OF BLOWING HIGH-OXYGEN GASES INTO A MOLTEN BATH WHICH CONTAINS NON-FERROUS METALS

ABSTRACT OF THE DISCLOSURE: The gases are injected through double-tube nozzles which extend through the wall of the reactor into the molten bath. A cooling protective fluid is injected through one tube of each double-tube nozzle. To reduce or avoid a wear of the double-tube nozzles and the surrounding brickwork, the flow rate of the protective fluid is so selected in dependence on the composition of the slag and on the difference between the temperature of the slag and its solidification point that crusts will be formed on the nozzles but will not exceed a desired thickness.

CONTINUOUS PROCESS OF SMELTING METALLIC LEAD DIRECTLY FROM LEAD- AND SULFUR-CONTAINING MATERIALS

ABSTRACT OF THE DISCLOSURE A molten bath consisting of a slag phase and a lead phase is maintained in an elongated horizontal reactor. The charge is fed into the reactor on one side thereof onto the molten bath in a melting zone so as to maintain an oxidation potential which causes metallic lead and slag to be formed. Reducing agents are introduced into the slag phase on the other side of the reactor in a reducing zone. To ensure that the bismuth contained in the charge will be collected in the smallest possible quantity of crude lead, such an potential is maintained in the molten bath in the melting zone that the lead phase contains 0.05 to 2 % by weight sulfur, the high-Bi primary lead which becomes available in that zone is separately tapped, and the low-Bi secondary lead which becomes available in the reducing zone is also separately tapped.

Pig stunning system - for abattoirs using microwave beam directed at temple

Animals (pigs) in abattoirs are stunned by directing a beam of microwaves through the temples into the brain so that this is heated to 41-50 degrees C. This causes unconsciousness within 1-10 sec. The frequency range is 100 to 10 000 MHz.

Apparatus for generating oxygen

The purpose of the invention is to maintain human life for as long and healthily as possible. This is to be achieved by enriching the inhalation air with oxygen. Thus, general well-being and a more active metabolism are to be promoted. By means of UV lamps, the apparatus generates ozone (O3) which is broken down by a catalyst into oxygen (O2). This pure, sterile oxygen is then supplied to the inhalation air within enclosed spaces in a dosage of approximately 15-20%.
