Title: Method and device for the electrical stunning of animals for slaughter
IPC: H05C1/00
Filed: 1981-03-13
Abstract: A new method for the electrical stunning of animals for slaughter is described, in which the stunning voltage is not applied as a step function of full magnitude but as a gradually increasing voltage to the stunning electrodes. During the voltage rise and at the end of the voltage rise, a constant intermediate or maximum voltage can be maintained for a short period. The stunning voltage can then once again be reduced gradually from the maximum value to a final value. The voltage values of the stunning voltage profile obtained by such measures can be adjusted individually for each animal to be stunned as a function of the electrical resistance of this animal, i.e. the stunning voltage can be metered individually depending on the vitality of the individual animal. <IMAGE>

Patent DE-3204072-A1 (DE)
Title: Radiation receptor for thermal radiation
Inventor: BRUEGGEMANN REINHOLD DIPL-ING
IPC: G01J5/12
Filed: 1982-02-06
Abstract: The invention relates to a radiation receptor for thermal radiation. Such radiation receptors are generally of only very low mass in order for them to be able to react sensitively to thermal radiation sources. As a result of the low mass, the radiation receptors are often, however, too sensitive, so that control systems in which such radiation receptors are arranged are too frequently engaged. In order to avoid this disadvantage, the invention makes provision for the connection, upstream of the receptor plate of the radiation receptor and at a distance in the radiation direction, of an additional, external receptor plate which is held at a thermally insulated distance from the internal receptor plate. This produces, without an appreciable rise in thermal capacity, a delay in the reaction of the radiation receptor, which permits operation with substantially longer times for the various reaction states.

Title: Method for the immobilisation of microbial cells with glucose isomerase activity
Inventor: POPOV MITKO STOJTSCHEV DR MED
IPC: C12P19/24
Filed: 1982-03-26
Abstract: The invention relates to a method for the immobilisation (biological fixing) of microbial cells which have glucose isomerase activity, in which the polymerisation induced by glutaraldehyde takes place in the presence of a protein carrier. The object of the invention is to provide a method for the immobilisation of microbial cells with glucose isomerase activity using an easily obtainable protein carrier, with the aim of obtaining a highly active and stable product which ensures the production of high-fructose syrups in a continuous technological process. In working out the method, the polymerisation induced by glutaraldehyde was applied to the cells with glucose isomerase activity. It was found that the glucose isomerase activity is retained when the polymerisation with glutaraldehyde takes place in the presence of blood serum or blood plasma as protein carrier.

Title: Settling device for septic sludge
Inventor: KREYENBERG HEINER DIPL ING
IPC: B01D21/08
Filed: 1982-09-11
Abstract: To remove septic sludge in the case of silted-up waters, flushing dredgers are conventionally used. Hitherto the resulting septic sludge transport water has been pumped into so-called flushing fields, to carry out a separation between septic sludge and excess water. Said flushing fields must each be newly constructed specially for each new use. To avoid this uneconomic process, the invention proposes a mobile, reusable, container-like vessel (1) as a settling chamber (2) equipped with a filling station (3) for feeding the septic sludge and a transfer station (4) for carrying away and further processing of the settled septic sludge.
