Patent CA-2137851-A1 (CA)
Title: Continuous Board-Making Press
Inventor: GERHARDT KLAUS
IPC: B27N3/20
Filed: 1994-12-12
Abstract: A press for making pressed board has a plurality of longitudinally spaced rigid frames, a lower press plate extending longitudinally through and secured to the frames, and a normally planar upper press plate extending longitudinally above the lower plate through the frames and defining with the lower press plate a longitudinally throughgoing press gap.  A plurality of vertically effective double-acting hydraulic cylinders carried on the frames above the upper plate each have a back compartment and a front compartment, are connected to the upper plate, and support the upper plate on the frames.  Respective upper and lower endless belts have respective lower and upper stretches extending through the gap immediately below and above the respective upper and lower plates and respective upper and lower rollers advance the stretches longitudinally through the frames.  Sensors connected to the lower plate produce an output corresponding to the size of the gap.  A safety unit connected to the upper plate produces an output when the upper plate is deformed to a predetermined extent from a planar shape.  A hydraulic valve system connected to the compartments of the double-acting cylinders pressurizes and depressurizes same.  A controller connected to the safety unit and valve system pressurizes the front compartments of the cylinders when the safety unit generates its output and thereby hydraulically blocks downward movement of the upper plate.  This arrangement obviates the use of mechanical stops for preventing contact of the press plates with each other. When the upper plate is deformed excessively, movement thereof is blocked hydraulically. The system is more flexible and adaptable to various working conditions.

Patent CA-2139905-A1 (CA)
Inventor: LEU WILLY
IPC: B42C9/00
Filed: 1995-01-10
Abstract: The multi-sheet, folded printed product arranged on the supporting member is penetrated by a penetration tool, from the direction of a supporting member. A pressure-exerting element acts on the printed product with a lateral compressive force. This results in a widening of the through-passage produced through the printed product. Upon withdrawal into the rest position of the penetration tool, adhesive present on the surface of the penetration tool is transferred onto the sheets in the through-passage. Once the lateral compressive force has been eliminated, the through-passage closes, which results in good distribution of the adhesive and reliable adhesive bonding.

Patent CA-2142393-A1 (CA)
Inventor: CHEN JUIN-HWEY
IPC: G10L19/00
Filed: 1995-02-13
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech. During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only. This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Abstract: An improved active power line conditioner is disclosed. The active power line conditioner includes a series inverter (52) coupled to an energy input source, and a parallel inverter (54) coupled to a non-linear load (56). The non-linear load (56) is pow-ered by a three phase load current which includes fundamental components and harmonic components.

The series inverter (52) is con-trolled by a series filter controller (68) which performs synchronous transformations on the load current to generate a series filter feedforward signal corresponding to the fundamental components of the load current. The series filter feedforward signal is ap-plied to the series inverter (52) to generate sinusoidal input currents for the non-linear load (56). The parallel inverter (54) is con-trolled by a parallel filter controller (64) which performs synchronous transformations on the load current or series inverter input voltages to generage a parallel filter signal corresponding to the harmonic ripple components of the load current. The parallel fil-ter signal is applied to the parallel inverter (54) to generate sinusoidal voltages for the non-linear load (56).

Title: Photodetector circuit with actively damped tuned input
Inventor: MILLER GABRIEL L
IPC: H04B10/43
Filed: 1995-08-17
Abstract: A photodetector circuit is disclosed which can extract a carrier frequency signal from an optical beam.   A photodiode is back-biased by a voltage supply, and the capacitance of the photodiode is dependent on the value of its back-bias potential.  The photodiode is connected in parallel resonance with an inductor, and the parallel resonant combination is connected to the input of an inverting amplifier having a feedback capacitor.   This feedback capacitor causes a capacitive component to appear in the input impedance of the amplifier which combines with the photodiode capacitance and the inductor to provide a parallel resonant tank circuit.  The amplifier has a change in gain versus change in power supply characteristic.  By selecting the value of the feedback capacitor, changes in the capacitive component of the input impedance are equal and opposite to changes in the capacitance of the photodiode, and the resonant frequency of the tank circuit is thereby essentially unaffected by changes in the supply voltage.  A resistive element is added to the feedback impedance in order to lower the Q of the tank circuit to accommodate input signals having broader bandwidth.  A frequency selective amplifying stage is added after the amplifier to help remove much lower frequency optical interference that is passed by the amplifier due to the broader bandwidth.

Title: Method and Apparatus for the Automatic Analysis of Computer Software
Inventor: SHAPIRO BENJAMIN V
IPC: G06F11/28
Filed: 1994-05-10
Abstract: A method and apparatus for the analysis of a computer process is disclosed. The method consists of the steps of analyzing a target process and constructing a model and repository which are representative of the control and non-control components contained within the original target process respectively. The resultant model and repository are executed, and their execution is representative of the original target process. Structures created during the execution of the model and repository assist a user to identify failures which occur during the execution, and then locate the fault(s) responsible for the failures as well as places within the target process where modifications due to new requirements are needed. An alternative form of object code is proposed which consists of two components, control and non-control components. Previously described model representing the control component constantly increases the intelligence of the resulting object code in respect to the target process being executed through the processes of propagation of elementary knowledge about the correctness or uncertainty of the target process elements execution.
