Abstract: METHOD AND APPARATUS FOR SECURE MESSAGE TRANSMISSION FOR USE IN ELECTRONIC FUNDS             TRANSFER SYSTEMS     Abstract An electronic funds transfer system wherein it is required that a bank be reasonably guaranteed that the two parties to a retail transaction (i.e., a person and a retailer), agree on the transaction before the funds transfer takes place. The message including the transaction information is encryp-ted by the person using a unique encryption key (Kp) stored in a highly secure storage location in his own personal portable transaction device (XATR) and his data storage and transfer card (DSTC) and this first encrypted message is sent to the retailer who doubly encrypts the initially received encrypted message from P under his own unique encryption key (KR) and this doubly encrypted message is sent to the bank.  The person also sends the transaction message to the retailer in clear, and the retailer first verifies the message and then, utilizing his own encryption key (KR), encrypts same and similarly sends it to the bank. The bank utilizing unique retailer and customer identifica-tion data sent with the message, accesses a "key" file and first extracts the retailer's key (KR) and decrypts a first portion of the message, extracts the person's key (Kp) and decrypts a second portion of the received message.  The bank then compares a predetermined portion of the transaction message originating with the person with a similar portion received from the retailer and if identical, it is presumed that both the person and the retailer agreed to the trans-action and the appropriate funds transfer is made.  If the messages do not agree, some sort of default procedure occurs.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided herein for producing bilayer vesicles from a colloidal solution comprising mixed micelles of a bilayer-forming sub-stance and a detergent.  The process comprises removing the detergent from the micelle-containing colloidal solution by means of flow-through dialysis so that the colloidal solution is dialyzed against a dialysis liquid in a chamber whose walls are at least partially formed by a semi-permeable membrane.  In such dialysis, the dialysis liquid is moved along the outer side of the semi-permeable membrane at a velocity such that the detergent concentration in the dialysis liquid, on at least 90% of the active sur-face of the membrane, is at most 10% of the detergent concentration in the micelle solution in contact with the other side of the membrane.  In addition, a homogeneous detergent concentration is maintained in the micelle solution by the movement of the micelle solution.  The bilayer vesicles produced thereby do not suffer from the undesired properties of inclusion of organic solvents, degradation of the bilayer forming substance, the formation of multi-lamellar structures and the formation of nonhomogeneous sized vesicles.

Abstract: STEEL WIRE FOUNDATION               Abstract of the Disclosure A foundation unit which, when assembled, can be col-lapsed for compact storage and shipping and later can be elevated to a fully expanded state.  The foundation unit includes a rectangular, grid wire top bearing structure, a rigid bottom substructure such as a wooden frame, and a series of spaced, parallel rows of substantially flat support members extending between the top bearing struc-ture and the bottom substructure.  The support members are hingedly secured to the top bearing structure and bottom substructure to permit reduction of the foundation unit to the collapsed state with the rows of support members lying essentially prone.  In the elevated state, the foundation unit includes stabilizers which are oppositely reactive and which prevent relative longitu-dinal translation between the top and bottom of the foundation unit.  Depending on the firmness character-istics required of the foundation unit, the flat support members can assume one of a number of different config-urations, offering total stiffness or varying degrees of recoilable compression of the foundation unit.

Abstract: ABSTRACT         A flat, elongated cover for a pool having a bottom and side walls, the pool containing a liquid, is substantially rigid and has a side  facing the liquid and an opposite side facing away from the liquid when the cover is in a floating position on the liquid.  The cover defines at least one elongated cavity extending in the direction of elongation of the cover, each cavity having a single flooding opening facing, and in free communication with, the liquid, the flooding opening being arranged in the region of one end of the cavity for flooding the cavity, a venting port arranged in the region of an end of the cavity opposite to the one end, a vent valve for closing and opening the venting port, and a connection to a source of a gas under pressure leading to the cavity for selectively supplying the gas under pressure to the cavity.  The mass of the cover in addition to that of the liquid flooding the cavity exceeds the mass of the liquid to be displaced.  The cover will gradually sink to the bottom when the liquid floods the cavity through the single flooding opening at the one end after the vent valve has been opened to permit the gas under pressure to escape through the venting port at the opposite end, the cover assuming an oblique position while it sinks as the liquid gradually floods the cavity from the one to the opposite end, and the cover will gradually rise in a like manner when the gas under pressure is supplied to the cavity and gradually displaces the liquid in the cavity through the opening at the one end.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is an apparatus,  and a related method, for the automatic detection of defects in manufactured parts, such as turbine blades and the like.   The apparatus includes a video camera, a thresholding module to provide a binary image of a frame of video data, a region growing module to define anomalous regions by associating contiguous picture elements indicative of surface anomalies on the part, and defect analysis modules for determining if a rejectable defect exists, based in a comparison between statistics with respect to the anomalous regions and predetermined rejection criteria.          Rejection may be based on region size, region shape, or region position and orientation with respect to neighboring regions.  Thus, a region may be rejected if  it  is nearly collinear with another region, even through neither region may itself be characterized as a rejectable region.

Abstract: SPECIFICATION     Title of the Invention:          UPGRADING METHOD OF HEAVY PETROLEUM OIL     Abstract of the Disclosure:           Disclosed herein is an improved upgrading method of heavy petroleum oil, which method combines thermal cracking and extraction steps systematically to obtain light oil, gas and residue.  According to the above method, the byproduct, residue, is drawn out in a liquid form and extracted with a part of the thus-produced light oil or a fresh supply of heavy petroleum oil, which light oil or petroleum oil serves as a solvent, so as to extract soluble components in the residue and to obtain the extraction residue as solid particles.  Since mild thermal cracking conditions are employed in the above method, it is possible to avoid unnecessary gasification of oil and concurrence of dehydrogenation.  It has thus become feasible to obtain intermediate fractions of good quality with high yields and to achieve effective utilization of tar components, which have been deemed as residue, while saving energy.
