Abstract: The invention relates to a heat exchanger 1 consisting of at least one heat exchanger module which is characterised by improved efficiency and a high permissible pressure difference between the two flowing media. Improvement in efficiency is achieved by means of profile elements 2 which are welted in a zig-zag fashion and have side walls 18 and intermediate elements 3 having cambers 4, 8 in each case. Furthermore, the heat exchanger 1 is characterised in that the profile elements 2 and intermediate elements 3 are welded to one another at their respective lines of contact 16, so that a high pressure difference is permitted. <IMAGE>

Abstract: A method of operating a vehicle engine equipped with a cruise control includes the step of operating the engine in accordance with fuel delivery limits within a first range of delivery limits when the speed of the vehicle is less than a first speed limit and the cruise control is engaged such that the engine is controlled to permit acceleration of the vehicle under substantially all operating conditions. The engine is operated in accordance with fuel delivery limits within a second range of delivery limits less than the first range of delivery limits when the speed of the vehicle is greater than the first speed limit but less than a second speed limit. The engine is operated in accordance with fuel delivery limits within a third range of delivery limits less than the second range of delivery limits when the speed of the vehicle is greater than the second speed limit whereby the engine is controlled to permit acceleration of the vehicle under less than substantially all operating conditions thereof. Such a method allows an operator of the vehicle to accelerate when traveling downhill beyond the second speed limit so that sufficient momentum can be gained to crest an upcoming hill.

Abstract: A method is disclosed for retaining access to deleted documents in a data processing system. In a data processing system multiple documents may be stored and accessed by a plurality of users. Each user may be authorized a particular access authority to a document which limits the activities that user may undertake with regard to that document. In accordance with the method of the present invention any user having access authority to a document may designate that document as a retained document. Thereafter, any attempted deletion of that document by the owner thereof will result in the retention of the document for those users who have designated it as a retained document. Further, any attempted alteration of the user's access authority for that document which results in a denial of future access will result in the automatic creation of a copy of that document with the user's original access authority. In this manner a user, having once been granted access authority to a document, may elect to designate that document as a retained document and thereby assure continued access to that document despite an attempted deletion of the document or an alteration of the user's access authority.

Abstract: The present invention presents a method of processing ferrous powder materials to produce small component parts exhibiting excellent soft magnetic properties, in particular, residual magnetic flux density. The processing steps involve, in part, mixing with a binder, dewaxing or presintering at a temperature higher than in the conventional dewaxing process, followed by final sintering and a further conversion sintering, at a temperature lower than in the conventional sintering process, to produce parts having density values of over 96 % theoretical density and excellent soft magnetic properties. The invented method is suitable for producing small component parts having sufficient strength and excellent soft magnetic properties to make them suitable for miniaturized electrical and electronic equipment.

Abstract: The present invention is a cylindrical container inner surface tester for detecting based on an image processing technology foreign substances, dust, scratches, etc. on the inner side surfaces of cylindrical containers such as aluminum cans. The present invention aims at solving the problem pertaining to the conventional technologies of differentiating the continuous tone of an image to detect white or black spots on the containers' inner surfaces. In the conventional technologies, a circular highlighted portion appears on an image and the intensity variations in the background are so complicated that defects cannot be easily detected. The cylindrical container inner surface tester of the present invention sets a threshold THD among the target picture element value PO (i,j) of a continuous tone image and the background picture element values PO (i+α,j) and PO (i-α,j) of the continuous tone image α picture elements forward and backward respectively along a scanning line of the continuous tone image of the inner surface of a test can viewed from its axis direction. The tester detects defects by determining that the target picture element indicates a defective valley when the following equations exist, and determining that the target picture element indicate a defective peak when the signs are inverted in the equations.       PO (i+α,j) - PO (i,j) > THD                 PO (i-α,j) - PO (i,j) > THD           
     Before detecting defects, the present invention extracts as a test area according to the continuous tone image signal 1a the diagonal-shaded area between the first rise point 61 and the last fall point 62 (or between 61 and 63, and 64 and 62 excluding a masked area 201) of a signal obtained by converting a multi-value continuous tone image signal 1a to a binary representation using the predetermined threshold THG. Furthermore, the continuous tone image of the test container's inner side surface is sequentially scanned along a ring or spiral circular scanning line Lk or Lk′, for example. An absolute value of the difference ΔP=∥P0 - P1∥ between the volue P0 of the target picture element on the circular scanning line and the value P1 of the background picture element separate from the target picture element by a predetermined interval of picture elements d is compared with a predetermined threshold THP corresponding to the position of the circular scanning line. If ΔP > THP, the target picture element indicates a defective inner surface such as a defective concave, etc. The cylindrical container inner surface tester is used for testing the inner surfaces of cylindrical containers such as beer cans while they are conveyed on a belt conveyor, etc.

Abstract: The supply device for finely granulated or powdery products, in particular for toner for toner cartridges of laser printers, photocopiers and the like, is characterised by a container (1) which receives the supply product and merges on the outlet side via a funnel-shaped wall part (2) into an inlet nozzle (3; 3') which is intended for insertion into a filling opening of a toner cartridge. The container comprises a closure pin or closure cone (5; 5') which can be displaced relative to the container (1) counter to the effect of a closing spring (4). It is thus possible to supply each toner cartridge, which is provided with a corresponding filling opening in a positive-locking manner with the inlet nozzle on the supply device, with toner quickly and completely cleanly as well as repeatedly, the pressure exerted for displacing the closure cone counter to the effect of the closing spring guaranteeing an effective seal between the inlet nozzle and the cartridge to be filled and thus preventing the toner being spilt into the surroundings. <IMAGE>
