Granted: 1995-09-26
Abstract: The invention relates to a spread of the water-in-oil type comprising an intimate mixture of particles of vegetable fats and of milk fat, wherein the spread possesses a structure which is to be obtained by forming an emulsion of at least water, molten vegetable fats and/or oils, a milk cream phase with a milk fat content of 5-70% and 0.5-3% of a lactic acid bacterial culture, subjecting this emulsion to a mechanical treat-ment while cooling to below 20°C and finally separating off the product obtained and storing it at a conversion temperature at which the lactic acid bacteria form lactic acid and butter aroma substances from substances belonging to the milk cream phase.   The total fat mixture preferably contains at least 40% poly-unsaturated fatty acids. The milk fat content of the milk cream phase preferably being 20-40%. The cream particles present after the mechanical treatment will separate out butter particles on storage. The cooling may be interrupted during the mechanical treatment. The conversion temperature is lower than 20°C. The spread is advantageously continuously prepared by forming an emulsion of at least water, molten vegetable fats and/ or oils, a milk cream phase with a milk fat content of 5-70% and 0.5-3% of a lactic acid bacterial culture, subjecting this emulsion to a mechanical treatment while cooling to below 20°C and finally separating off the product thus obtained and storing it at a conversion temperature at which the lactic acid bacteria form lactic acid and butter aroma substances from substances belonging to the milk cream phase.

Title: Integrated two reaction zone process for c4, c5 and c6 isomerization
Inventor: JOHNSON BRIAN H
IPC: C07C9/16
Filed: 1991-06-25
Granted: 2001-08-21
Abstract: A C4 feedstock and a C5-C6 feedstock are isomerized in a process that reduces equipment and operating expenses by utilizing a process flow scheme that provides beneficial heat integration and facilitates the use of common recovery zone while permitting a wide variation in the relative ratio of a C4 to a C5-feedstock. The isomerization of the C4 feedstock first takes place in a separate reaction zone. The effluent from the C4 isomerization zone is heat exchanged against or mixed with the C5-C6 feedstock ahead of an additional isomerization zone that converts the C5-C6 hydrocarbons, and if present, normal C4 hydrocarbons, to more highly branched hydrocarbons. Effluents from both isomerization zones enter a common separation section that removes light gases from the isomerate product.

Inventor: HAN HAK-RHIM
IPC: B65D77/20
Filed: 1990-01-17
Granted: 2000-01-04
Abstract: A z-tab innerseal for a container and method of application involves an innerseal (18) having a first sealing portion (20) for sealing a first portion of an opening defined by an upper rim of a container, a second sealing portion (22) for sealing the remainder of the container opening and a flap portion (24) between the first and second sealing portions which is adapted to be grasped and pulled upwardly by a user to remove the innerseal from the container opening. An advantage of the flap portion is that it allows the innerseal to be removed without having to penetrate or scrape the innerseal with a sharp object such as a knife. A method of forming the improved innerseal includes providing a blank of stock material having a folded portion, cutting the blank to form an innerseal, mounting the innerseal onto the rim of a container and sealing the innerseal to the container by passing the assembly through a heating station.

Filed: 1993-03-04
Granted: 2003-09-23
Abstract: A continuous process for the non-destructive recov-ery of natural nitrogenous materials as highly available particulate agricultural nutrients is described. The pro-cess employs natural materials such as poultry waste, waste water treatment sludge, alfalfa meal, hatchery waste, fea-thermeal, corn gluten meal, and bloodmeal in a fluid bed reactor-granulator. The natural materials, which are basic in nature or have been made basic, are acidified to pHs of about 3.0 to 6.5 in the reactor-granulator and formed into hardened particulates during a retention time of between about 4 to 20 minutes at a temperature between about 70-120°C. The particulates are discharged free of carameliza-tion and before nitrogen loss from decomposition amounts to 0.5 percent of the natural nitrogenous materials. The con-tinuous process provides a new natural nitrogenous particu-late agricultural nutrient composition free of carameliza-tion.
