Title: Finger-protection device for a roller gap
Inventor: CASTNER HORST
IPC: B29C43/24
Filed: 1994-05-17
Abstract: A finger-protection device for a roller gap of a paper-calendar with heated rollers has a hollow body (4) extending along the roller gap, with a front wall (5) facing a roller (3), defining the roller gap, a dome shaped rear wall (6), and two end walls (8). The strips (9, 10) forming the longitudinal edges of the front and rear walls are at an angular position in relation to the front and rear walls (5, 6) and are directed to the rollers (2, 3) limiting the roller gap.  They provide a maximum distance d from the rollers (2, 3), which does not permit the passing through of one's fingers between a longitudinal edge and the adjacent roller (2, 3). The hollow body (4) is supported at its ends and can be adjusted relative to the rollers (2, 3). In order to simplify the manufacture and operational handling of the finger-protection  device (1, 2) and  also  maintain  a non-exceedable  maximum  distance  d  to  the  rollers  during  the operation,  the hollow body  (4)  consists of fiber-reinforced synthetic resin plastic.  The front and rear walls (5, 6) are made as separate units and connected to each other.  The strips are formed by front and rear walls (5, 6) as a one piece construction and as flanges (9a, 9b; 10a, 10b) connected to each other.  The end walls (8) are produced separately and connected to the front and rear walls (5, 6) or are produced as a one-piece unit with one of the front and rear walls.

Patent CA-2147671-A1 (CA)
Inventor: CHENG KWANG-TING
IPC: G06F17/50
Filed: 1995-04-24
Abstract: The present invention provides a method and apparatus for more efficiently validating high-level specifications of sequential digital systems, and in particular, those represented by hybrid models.  According to the present invention, the high-level representation of a system is converted into a direct sum EFSM.  An operator or a data file then provides an initial configuration or set of initial configurations of states and variable values.  The method of the present invention then determines the set of configuration reachable from the initial configuration through symbolic execution of the direct sum EFSM.  By representing the transitional relations of the machine as the and-product of Boolean expressions and arithmetic expressions, each class of expressions may be processed separately.  When complete, the symbolic execution produces a cover of the set of reachable states.  The results may then be reviewed to determine if the given specification produces unexpected or incompatible results. hcmze-15.app

Patent CA-2155347-A1 (CA)
Inventor: HAULIN TORD LENNART
IPC: H03K5/14
Filed: 1994-02-23
Abstract: The present invention provides a bit synchronizer for the interpretation of a bit data stream received in a receiver when strobed by an isochronous or plesiochronous clock signal which lies in the time domain of the receiver. This is achieved by alternate activation and deactivation of a first and a second phase aligner respectively, based on monitoring a delay controlled voltage of the active phase aligner. These phase aligners each utilizes differential delay lines which are comprised of differential delay elements, which in turn are comprised of pairs of inverting devices, where both devices of each pair have a controllable delay for positive edges and a pulse restoring function for negative edges, alternatively a controllable delay for negative edges and a pulse form restoring function for positive edges. Because each DDE is constructed symmetrically, feedback from the outputs Q and ? on INV2 can be easily effected to the inputs FB and ? on INV1, and from the outputs Q and ? on INV1 in a delay element can be readily fed back to the inputs FB and ? respectively on INV2 in the preceding delay element. Because the feedback route quickly changes the ramp edge to full logic level as soon as the treshold voltage has been reached in the inverting device, the preceding stage is prepared for the restoring function that it will have for the next data edge, thereby avoiding interference effects.
