Patent EP-0313756-A3 (EP)
Title: Reactor for treating bulk material or the like
IPC: B01J8/10
Filed: 1988-08-25
Abstract: In reactors for treating bulk materials, with a vessel which can be sealed pressure-tight, and an agitator arranged therein, whose horizontally extending shaft protrudes through the end walls of the horizontally arranged product vessel, the shaft is mounted in bearings located outside the product vessel. The sealing of the shaft seals through the end walls of the product vessel is difficult because of the pressure differences between the external air and the interior space of the product vessel. In the novel reactor, this sealing problem is to be reduced by simple means. Although one of the two bearings of the shaft is also arranged outside the product vessel, it is hermetically encapsulated against the outside, a pressure equalisation being effected directly or indirectly between the housing forming the encapsulation and the interior space of the product vessel, so that the same pressure applies on both sides of the seal. In this reactor, in the region of the bearing hermetically encapsulated against the outside, there is no risk of product escapes at the seal due to pressure differences. Accordingly, the seal in this region can be of simpler design. <IMAGE>

Patent EP-0304115-A3 (EP)
Title: Marine/vegetable oil blend and products made therefrom
IPC: A23L27/60
Filed: 1988-08-03
Abstract: The specification discloses a method for the preparation of a bland, keepable marine oil/vegetable oil which does not contain hydrogenated marine oil. The blend will retain its blandless for at least three months without development of a "fishy" odour and can be used for frying, baking or the preparation of edible compositions such as margarine. The result is achieved by blending the oils during or shortly after a refining process and overcomes the long-standing requirement that marine oils should be hydrogenated before use in edible compositions.

Patent EP-0370341-A3 (EP)
IPC: A61B5/352
Filed: 1989-11-11
Abstract: A method of reducing image artifacts in tomographic, projection 
imaging systems due to periodic motion of the object being 
imaged includes the acquisition of a signal indicative of the 
periodic motion. This signal is used to identify a quiescent 
period in the periodic motion so that the acquisition of 
projection data may be coordinated to be centered within the 
quiescent period. The sequence of the angles at which 
projection data is acquired is controlled so that the primary 
axis of periodic motion is perpendicular to the axis of 
projection at the center of the quiescent period. Multiple 
periodic signals may be coordinated by awaiting their best 
alignment over a fixed number of cycles of one of the periodic 
motions.
