  • Patent number: 6162478
    Abstract: The invention relates to a process for preparation of hen's eggs during which the eggs are put into a cooking chamber of an egg-cooking container (2) closeable by a cover (8), which chamber contains a liquid heat-supplying medium, preferably water. The preparation temperature during a first preparation stage is below the boiling temperature of the water, and during a following second preparation stage is held below the temperature of the first preparation stage but above 55.degree. C. During the first preparation stage, the water starts at a temperature of approx. 55.degree. C. and is heated at a high heating rate to a temperature of at least 90.degree. C. during a first period with the result that the eggs rapidly reach a core temperature of approx. 58.degree. to 75.degree. C. At the start of the second preparation stage, the water temperature is reduced at a high cooling rate to a final temperature of between 80.degree. C. and 55.degree. C.

  • Patent number: 5519948
    Abstract: A process for the production of pourable, free-flowing granules which are suitable for use as wetting agents, detergents or cleaning products from aqueous solutions or suspensions of such materials in a fluidized-bed spray granulation apparatus employing a hot fluidizing gas. The aqueous selections or suspensions are dried with superheated steam as the fluidizing and drying gas wherein the drying step is carried out in a closed-loop system comprising a steam circuit from which the water evaporated from the aqueous solutions or suspensions of starting materials is removed as a partial stream and the thermal energy released is returned to the steam circuit. The granules are discharged from the granulation apparatus before they can be damaged by heat.

  • Patent number: 4969671
    Abstract: A gas-tight joint for pipe linings and risers inside a bore, consisting of a neck with an outside thread and of a matching collar with an inside thread, with a groove in the vicinity of the thread on the collar and/or of the thread on the neck to accommodate a deformable gasket that, when the joint is screwed tight, is demarcated and deformed by the base of the groove in the neck and/or in the collar and by the contour of the thread on the other component.

  • Patent number: 4823847
    Abstract: A method for production of a multi-layer gap-less steel pipe. An inner pipe and an outer pipe are formed from thermomechanically rolled steel strip with high notched bar impact strength by welding. The individual helical welding seam steel pipes of about the same lengths are matched with a difference of less than about one percent between the outer diameter of the inner pipe and the inner diameter of the outer pipe. The matched inner pipe is inserted into the outer pipe and the pipes are mechanically expanded with diameter control to a preset outer diameter of the multi-layer steel pipe. The resulting multi-layer steel pipe has the inner pipe disposed under compression and the outer pipe layer disposed under stress. The presence of a compression stress in the inner pipe provides a means opposed to hydrogen sulfide stress corrosion.
