Abstract: COMMUNICATION CHANNEL OWNERSHIP ARRANGEMENT Abstract A communication channel ownership arrangement where two call units (switching modules) each own certain ones of the bidirectional channels between the units. By virtue of ownership, a call unit can immediately assign owned channels to calls without consulting the other call unit. While the ownership of channels to calls may be arbitrary at system initialization, ownership is modifiable on a per-call basis to dynamically adapt to the actual directionaltraffic patterns that are present at a given time to minimize the coordination and communication required between the call units.

Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a process for preparing 2,2-bis(4-hydroxyphenyl)propane (bisphenol A) by reacting acetone with phenol and decomposing the resultant adduct of bisphenol A and phenol. The quality of bisphenol A thus obtained is not always satisfactory.  The adduct is washed with phenol recovered by decomposing the adduct of bisphenol A and phenol, and then bisphenol A is prepared by decomposing the washed adduct.  The bisphenol A prepared by this process has an extremely high quality and is suitable for the preparation of polycarbonate used for optical parts.

Title: Valuator menu for use as a graphical user interface tool
Inventor: GEST STEPHEN B
IPC: G06F3/033
Filed: 1989-02-03
Granted: 1993-02-02
Abstract: Abstract of the Disclosure The system and method of this invention provides a user interface tool for simultaneously selecting a menu item and a value, from a range of values, for the menu item.  The user interface tool of this invention is referred to as a valuator menu, since it allows both the selection of a value from a range of values, and the selection of a menu item from a menu list.    As a user moves a cursor over a menu of select-able items on a screen display, the item underneath the cursor is highlighted. In addition, as the user moves the cursor within the highlighted menu item, a value relative to the position of the cursor within that menu item is displayed.  This valuator value is dynamically updated as the cursor position changes within the menu item.  When the user performs an input selection, i.e. through a mouse button or a keyboard interaction, both the selected menu item and the value, relative to the cursor position, are simultane-ously returned to the application program running on the data processing system.

The detonator (70) is adapted to be driven by a pulse of electric power from an external source (80).  A conductor (20) is disposed along the top (14), side (18), and bottom (16) surfaces of a sheetlike insulator (12).  Part of the conductor (20) comprises a bridge (28), and an aperture (30) is positioned within the conductor (20), with the bridge (28) and the aperture (30) located on opposite sides of the insulator (12).  A barrel (40) and related explosive charge (50) are positioned adjacent to and in alignment with the aperture (30), and the bridge (28) is buttressed with a backing layer (60).  When the electric power pulse vaporizes the bridge (28), a portion of the insulator (12) is propelled through the aperture (30) and barrel (40), and against the explosive charge (50), thereby detonating it.

Title: Error location system
Inventor: WENG LIH-JYH
IPC: G06F11/10
Filed: 1989-05-11
Granted: 1993-03-30
Abstract: ABSTRACT    The invention is an error correcting system which calculates the error locations, that is, finds the roots of the error locator equation: 1 + ?1*x + ?2*x2 + ?1x3 + ... + ?v-i*xv-i + ?v*xv = 0   (1) where "+" and "*" represent Galois Field addition and Galois Field multiplication, respectively, and "v" is the number of errors in the data by substituting the error location equation coefficients into a succession of v error location formulas along with successive values of x to determine if the various x's are roots of equation (1). When the first root is found, extraction of the root corresponds to reducing the degree of equation (1) by one, to (v-1), and also to reducing the number of error location formulas by one to (v-1).  Thus substitution in the error location formulas of further values of x to find the next root requires one fewer addition operation and one fewer multiplication operation.  When another root is found, the error location formulas are further reduced by one.  This procedure is repeated until, depending on the system utilized, all v roots are found or v is reduced to a value of 2, 3 or 4, and a fast-decoding method is utilized to find the remaining roots.

Abstract: A method of forming an extrusion die comprises forming an extrusion aperture 11 in a die piece 10, forcing a flowable materiat 14 partly through the extrusion aperture so that the leading surface of the material becomes deformed in the extrusion direction, and then removing the exposed surface of the extrusion aperture 11. by chemical or electro-etching, so that the effective axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location. The axial bearing depth of the completed die at any location is thus inversely proportional to the resistance to flow at that location, resulting in substantially uniform flow over the whole of the die aperture.

The planar portions extend between the flat edge and the convex edges, with the convex edges being joined by a concave edge located opposite the flat edge and between the convex edges which defines a narrowed webbed portion extending integrally between the planar portions. An elongated deformable flexible sealing member extends along the flat edge between the distal ends of the flexible member and a second elongated deformable flexible sealing member extends continuously along the convex edges and the concave edge between the distal ends of the flexible member. An elongated band connected between the distal ends of the flexible member attaches the flexible member in an arcuate shape around the head with the spaced planar surfaces located above and covering the eyes and the web portion extending transversely across the nose.

Abstract: 1486519 Identifying and counting coins NGZ GELDZAHLMASCHINEN GmbH & CO FERTIGUNGS-KG 9 April 1975 [19 April 1974] 14551/75 Headings G4V G4X and G4D Apparatus for identifying and counting coins comprises an optical signal transmitter controlling a counter in which the signal transmitter is formed by an optico-electronic image converter past which the coins are adapted to be guided and which supplies signals representative of the respective coin surfaces, the said signals being fed to a comparator which in its turn feeds the counter with signals associated with the coins. Coins are fed from a trough 13 to a rail 15 by conveyer 14. A rocker member 16 permits coins to pass to rail 18 when in a closed position but when open coins fall on to conveyer 17 and are passed back to the trough. Coins passing along the rail pass image converter 19 consisting of four solar cells 20. A light source 21 projects rays through a condenser 22 to the solar cells. From the rail coins pass through shoot 23 into distributor shoot 24 and thence into through one of passages 27 into a container 29. Shoot 24 is positioned by a step-by-step mechanism 26. Fig. 2 shows how rocker member 16 is rotated to an open position by magnet 38 when it receives a signal from photo-electric cell unit 36 via store 37, that a coin has passed. The member 16 is closed when the counting operation in respect of a coin is completed. When a coin passes image converter 19 there is a decrease in the output voltage of a summation or adding unit 39. If the value is below an adjustable reference level comparator 41 prepares for an evaluation instruction. This occurs when the solar cells 20c and 20d are covered by equally large amounts which causes zero-pasage discriminator 42 to pass from a low level to a high level position. After delivery of the evaluation instruction store 37 is returned to its initial position. Also by means of an eight-channel analogue comparator 43 and a coder 44, a channel number is fed into an intermediate store 45 when there is voltage parity between the output voltage of summation unit 39 and a reference level adjusted by reference level adjusting unit 31. The reference levels correspond to the normal dimensions of the coins of a coinage system. The channel numbers are supplied to a counter 46 which has a valuation stage, an adding mechanism 48, a store 49 and an indicating means 50. A metal senser 51 prevents the use of counterfeit coins. For coin sorting, the difference between a channel number which is stored in an intermediate store 45 and the counter content of a forward and backward counter 54 is determined in a comparator stage 53. Depending on the difference an instruction is given to control means 55 of mechanism 26.
