Granted: 1999-04-10
Abstract: FIELD: power and nuclear machine engineering, particularly production of tubular heat exchangers. SUBSTANCE: method for connecting tubes with tube plates comprises steps of expanding tubes and inserting unclamped annular welding electrodes to expansion zone for applying to them (at end period of expansion process) welding current for annular contact welding of tubes with tube plate. Novelty is tube expansion along limited-width annular portions in predetermined zones along thickness of tube plate. At first such expansion of all tubes is realized in zone of rear end of tube plate and tubes are tack welded by annular seam. Then strength of all joints is checked, detected defects are eliminated by repeating expansion process and tack welding of all defective joints. The same expansion and tack welding by annular seam is realized in zone of front end wall of tube plate. Apparatus for performing the method includes power cylinder with stop for limiting depth of rod insertion into tube, removable head on end of rod, two changeable cylindrical spacing sleeves freely mounted on rod, turned one to another and having ends with cone surface. Unclamped annular welding electrode in the form of slit collar made of set of sectorized slide blocks movably joined one with another in radial direction is arranged between changeable sleeves. End portions of slit collar have cone surface and they engage with ends of spacing sleeves. Novelty is welding electrode with function of expanding member.

Abstract: FIELD: methods of selection of radial hole coordinates for cylinder mechanism of lock combination. SUBSTANCE: lock consists of body, turning bushing with which central core is rigidly connected and tubular key is inserted into round slot located between turning bushing and central core. The method allows increase of lock combinations, and consists in selection of coordinates and filling with two groups of spring-loaded members of holes with code by selected coordinates. The first group pf spring-loaded members ensures locking of turning bushing with any inserted key made with some other code. The second group ensures locking of turning bushing with key withdrawn. In each group, one member is supporting and contacts with central core. With key inserted, coming in contact with central core are supporting members of the first group only. Located coaxially on drawings of body, turning bushing and tubular key are coordinates of possible holes which cannot be all together made without crossing of their surfaces in key. Holes are made with coordinates selected from coordinates of possible holes with consideration of limitation excluding possibility of crossing of surfaces of selected holes. In this case, minimal distance between coordinates of possible holes is determined proceeding from the condition which ensures impossible touching of central core by supporting members from the first group of sets with any inserted key in which holes are made by some other code. Gaps between these supporting members and central core in this event shall be such that turning bushing remains locked. EFFECT: higher efficiency. 3 dwg

Title: System and methods of acquisition, analysis and authentication of the handwritten signature
Inventor: MOISE GABRIEL ALEXANDRU
IPC: G06V40/30
Filed: 2006-02-01
Granted: 2009-07-09
Abstract: A person making a handwritten signature performs a series of three-dimensional movements with a plane graphical finality. The movements generate kinetic information perceived by a special pen that the signature is performed with (the writing and digital acquisition device for the primary bio-kinetic information). The information, concordant to the afferent bio-kinetic pattern, is collected by included MEMS type acceleration sensors in the pen. The system analyzes the generated information (the signals) and determines the dynamic-biometrical characteristics based upon the biometrical dimension of the information. The characteristics are transformed into data vectors and invariants that are stored in a database. Based on algorithms, the system performs the required comparisons between the spatial kinetics of the specimens and the kinetics of the entrances and obtains distance-type answers. In statistical terms, the results are related to the entire subject database, by interpreting and sampling methods.
