Abstract: A mortise latch and exit device includes active and passive mortise latch mechanisms with corresponding concealed vertical rods operated by links mounted within the mortise latch mechanisms. The mortise latch mechanisms latch double doors at a center point between the doors and at top points between each door and the door frame. Lower vertical rods may also be used to latch at bottom points between the doors and the floor. The active and passive mortise latch mechanisms are operated by corresponding push handle mechanisms and rotary handles. The mortise latch mechanisms cooperatively interact so that either door may be opened first, and either door may be closed first, without regard to the position of the other door. The active mortise latch mechanism includes a latch bolt and an activation bolt arranged so that one bolt is retracted when the other is extended, except when the doors are being opened or closed, when both bolts are retracted. The active mortise latch mechanism automatically retracts the latch bolt when the doors are not aligned and automatically extends the latch bolt when the doors are aligned.   The passive mortise latch mechanism ejects the latch bolt as needed to allow the passive door to be opened first.

Abstract: In a method for generating electrical conducting or semiconducting structures in three dimensions in a matrix which comprises two or more materials in spatially separated material structures, an electric field is applied to the separate material structure or the field-modulated spatially according to a protocol which represents a predetermined pattern of electrical conducting or semiconducting structures which are generated in the material structure in response to the field. The matrix composed by the material structures will hence comprise structures of this kind in three dimensions. In a method for global erasing an electric field is applied to the matrix until the materials in the matrix in response to the field in their entirety arrive in a non-conducting state. In an electric field generator/modulator (EFGM) which can be used for patterning and generating electrical conducting or semiconducting structures, two electrode means (E1;E2) comprise parallel strip electrodes (21;22) provided mutually spaced apart in parallel planes such that the electrodes (21, 22) form a matrix-like arrangement. The electrode means (E1;E2) are over cross-connection devices (24, 25) connected with a power supply (23). EFGM (20) is adapted for receiving a thin-film material between the electrode devices (E1, E2) in order to generate said structures.

Title: Method and apparatus for determining the provenance of a data carrying disc
Inventor: HEYLEN RICHARD A A
IPC: G11B23/30
Filed: 1999-09-29
Granted: 2009-03-17
Abstract: The manufacturing process for a data carrying disc, such as a CD, begins with the production of a master, and in the physical manufacturing process of the master, variations are introduced which give the master distinctive physical characteristics and cause errors in the data. The master is used to form generations of discs, and the physical characteristics of the master are passed on down the generations.  A group of discs manufactured from the same source consistently exhibit the physical characteristics of the master, and those physical characteristics are used as a "fingerprint" for identifying that source. To determine the provenance of a data carrying disc, uncorrected data is read from the disc. Information about errors is extracted from the data read. The error information is then compared with characteristic error information which characterises data carrying discs produced from a well known source to determine whether the data carrying disc has been produced from the known source. The error information extracted is representative of errors arising from the physical manufacturing process.
