Abstract: A method for recognizing the layout pattern of radiation images comprises the steps of preparing two-­valued masks, each composed of a two-valued signal representing a layout pattern for radiation images which are to be stored on a stimulable phosphor sheet, and obtaining a preliminary read-out image signal by carrying out preliminary read out on a stimulable phosphor sheet on which radiation images have been stored. The layout pattern of the radiation images is recognized by converting the preliminary read-out image signal into a two-valued image signal, calculating rating values, which represent the degree of pattern matching between the two-­valued image signal and the two-valued masks, finding the highest rating value that represents the highest degree of pattern matching among the rating values, and comparing the highest rating value with a predetermined value representing a predetermined degree of pattern matching.

Abstract: A method for fine decomposition in finite element mesh generation, in which a polygonal boundary of a domain is input into the system by an analyst and the domain is automatically divided into rough elements generally corresponding to Voronoi regions, that is, regions which are closer to respective ones of the polygonal line segments or reflex vertices therebetween. Any arc portion of these regions is converted to a straight line. Additional lines are formed between interior vertices of the rough regions so that all rough regions are either triangles or trapezoids. Adjacent rough regions are then paired across internal boundaries and are classified into four types. The rough regions are then subdivided into fine regions of triangular shape according to rules associated with each of the four types. The degree of fine subdivision can be controlled according to known equations providing the total number of fine elements. Finite difference equations are solved on the so generated fine regions and a physical variable is displayed in pictorial form. The analyst then readjusts the domain boundary and repeats the process.

Abstract: An optical fiber sensing system for detecting intrusion of optical fiber or optical fiber cables includes an interferometric arrangement. Two ports (28, 30) of a four port splitter (25) are connected to a source (26) of optical power such as a laser, for example, and to a detector (32). The other two ports (46,48) are connected to ends of a length (50) of monitoring optical fiber. An input signal to the splitter is split with one subsignal being directed in one direction around the length of optical fiber which serves as a common path between the two ports. The other signal is caused to travel around the common path in an opposite direction. The split signals are recombined in the splitter and their phase difference measured as a detectable pattern by the detector. Should there be intrusion of the optical fiber or a cable containing the monitoring optical fiber, the pattern which is detected will change a significant amount.

Abstract: A line noise signal measurement system (10) is provided with detecting circuitry (16) for providing a sensed analog signal. Compression circuitry (18) is cou­pled to the detecting circuitry (16) for providing an am­plitude compressed signal responsive to the applied sensed signal. The compression circuitry (18) has a stepwise sub­stantially linear transfer function responsive to a vari­able magnitude of the applied sensed signal. Signal pro­cessing circuitry (20, 22, 24) is coupled to the compres­sion circuitry for sequentially generating a digital signal representative of the sensed analog signal. Digital pro­cessing circuitry (14, 26) sequentially identifies a maxi­mum peak signal for a predetermined time interval and pro­vides linearity correction for the identified maximum peak signals and generates a display (FIG. 4) of the corrected peak signals.

Title: Device for processing photosensitive material
Inventor: GOERTZ VIKTOR DIPL-ING
IPC: G03D3/10
Filed: 1990-12-12
Abstract: Arranged sequentially in a development device are troughs having processing fluids required in accordance with the development process. The photosensitive material to be developed is sequentially guided by a transport device in a manner capable of being dipped into the individual troughs. In order to relieve the operator, and yet to develop a cost-effective device, it is proposed to build up the transport device from two assemblies. The first assembly consists of a lifter for each trough having openings, pointing in the sequence of the troughs, for inserting and removing the photosensitive material. In the manner of a lift, these lifters can be moved up and down between an immersion position and an extended position with respect to the trough assigned to them. The second assembly consists of limits before each receiving opening when the lifter is in its extended position. The limits are arranged above the troughs and belong to a slide. The slide can be displaced backwards and forwards in the sequence of the troughs between two end positions, the limits shifting in this process from one trough to the next. The lifting cycle of the slide and the reciprocating cycle of the slide are tuned to one another in a phase-shifted fashion. <IMAGE>

Abstract: The drive mechanism of a vacuum interrupter (1) has a two-armed lever (7), supported such that it can pivot, and a spring (11) which engages on the lever and provides the contact force. The two-armed lever (7) is guided in its bearing (oblong hole 9, pivot pin 8) such that it can move in a limited manner in a direction running approximately parallel to the direction of operation of the interrupter (1). On switching on, the two-armed lever (7), with its pivot pin (8), pivots about the end of the pin guide until the switching pieces (3, 5) make contact. Further pivoting of the lever (7) takes place about a hinge arrangement (6) between the two-armed lever (7) and the drive ram (4). The two-armed lever (7) can be formed from two parallel partial levers (20) at such a spacing that the spring (11) can engage between the partial levers. The drive mechanism is suitable for single or multipin vacuum power circuit breakers, for example for use in gas-insulated switching installations.

Abstract: A method of manufacturing a vehicle seat cover and bonding the vehicle seat cover to a foam bun utilizing a style insert. The style insert is formed by taking a breathable cloth fabric and laminating it to a sheet of foam material. The composite so formed is then cut to a desired styled insert shape and sewn to the vehicle seat cover skirt to form a seat cover assembly. 
     The composite, which may include an air impermeable barrier sheet or the barrier sheet may be included in the composite between the foam and fabric sheets, is positioned on a forming tool having removable style inserts, with the cloth side of the composite against the insert. An impermeable film is then positioned over the foam side of the insert composite and a vacuum drawn between the forming tool and the impermeable film to draw the composite down into conformity with the style lines of the tool insert. An adhesively coated foam bun is then positioned and pressed against the composite on the forming tool. Heat is applied to the forming tool to evaporate the film, allowing the adhesive to bond the cover assembly to the foam bun and release the composite from the forming tool allowing removal of the seat assembly from the forming tool. The edges of the skirt are then fastened together or to the underside of the foam bun so as to at least partially enclose the bun.

Abstract: A multinodal system is one-way interconnected, two-way interconnected or, more generally, ( n )-way interconnected, where ( n ) is an integer. In a one-way interconnected system, only one connection element couples any two nodes. Or, put another way, only one communication path exists between every node and every other node. A two-way interconnected system, on the other hand, has two connection elements coupling each pair of nodes. Likewise, an ( n )-way interconnected system provides ( n ) independent connection paths between each pair. Such systems are characteristic in that the relationship between the number of independent buses ( b ), the number of nodes ( v ), the number of ports ( r ), and the degree of interconnectedness ( n ) can be expressed by the equation
       
 Two-way and ( n )-way interconnect arrays may be adapted for use in fault-tolerant communications.
