Patent CA-2075124-C (CA)
Title: Circuit board shipping carton
Inventor: SEEFELDT ROGER LEE
IPC: H05K13/00
Filed: 1992-07-31
Granted: 1995-12-26
Abstract: A carton for use in shipping circuit boards. The carton has a pair of side members separated by top and bottom members configured to surround a circuit board with a closed end opposite an open end for receiving the circuit board. The closed end consists of three panels with one panel positioned perpendicular to the side members and a middle panel inserted into the carton cavity parallel to one side member with the remaining panel formed at an acute angle with respect to the middle panel inside the carton cavity to engage and position a circuit board within the carton to prevent longitudinal thereof. A segment formed at the open end across the top member to extend partially down each side member is formed such that oneside section rotates with respect to a side member so that a top section may be positioned parallel to the side member with the other side section positioned across the open end to retain the circuit board within the carton.
Patent CA-2082086-C (CA)
Title: Correlated active attenuation system with error and correction signal input
Inventor: ERIKSSON LARRY J
IPC: G10K11/178
Filed: 1992-11-04
Granted: 1996-09-03
Abstract: An active acoustic attenuation system atten-uates a correlated input acoustic wave and eliminates the need for an input transducer sensing such wave.  An output transducer introduces a canceling acoustic wave to attenuate the input acoustic wave and yield an attenuated output acoustic wave.  An error transducer senses the output acoustic wave and provides an error signal.  An adaptive filter model has a model input, a model output outputting a correction signal to the output transducer to introduce the canceling acoustic wave, and an error input from the error transducer.  A summer has a first input from the model output, a second input from the error transducer, and an output outputting a resultant sum to the model input, such that the model input is provided by the sum of the correction signal and the error signal.

Granted: 1996-11-26
Abstract: A dielectric filter having at least two adjacently-positioned resonators extended therethrough. The two adjacently-positioned resonators are of trapezoidal cross-sections to form thereby trapezoidal resonators. By suitable selection of the configurations of such resonators, the amount of coupling between such adjacent resonators may be controlled. For instance a minor base side of the first trapezoidal resonator may be positioned adjacent to a corresponding minor base side of the adjacent trapezoidal resonator, or a major base side of the first trapezoidal resonator may be positioned adjacent to a major base side of the adjacent trapezoidal resonator, or a minor base side of the first trapezoidal resonator may be positioned adjacent to a major base side of the second trapezoidal resonator. Such electromagnetic coupling between the adjacent resonators is controlled by the relative configurations of such resonators rather than by increasing the spacings between such adjacent resonators.

Abstract: A  process  for  controlling  a  variable  in respect  of  material  in  a  series  of  interconnected vessels of a plant includes monitoring a variable in respect of each vessel.   The monitored value of the variable is compared with a set point value of the variable.  The differences between said monitored values and set point values of the variable resulting from at least  one  disturbance  are  summed.    When  such  a disturbance  in any one  vessel  results  in  a  signal representative of said summed value being generated, each of a plurality of  actuators of  the plant are manipulated in a predetermined direction from said one vessel to cause rapid reduction of the disturbance.  The invention extends to a control system for controlling a variable  in  respect  of material  in  a  series  of interconnected vessels of a plant;

Title: Die-casting of metals with dispersion of solid particles in resulting castings
Inventor: DUSABLON ANDRE
IPC: B22D17/02
Filed: 1995-07-10
Granted: 1999-05-25
Abstract: The invention provides a method of die-casting of metals,  with dispersion of predetermined quantities of solid  particles  in  resulting  metal  castings.  This  is achieved by inserting a cartridge into the runner system, which cartridge is normally sealed at both ends with foil and  contains  the  predetermined  quantity  of  the  solid particles. When molten metal is injected through the runner system and thus through the cartridge,  it entrains the solid particles therewith which are thereby intermixed with the molten metal and form the composite material of which the die-cast part is thus made. The cartridge is preferably formed of the same metal as the one used for the die-casting, so that it may then be recycled.

Granted: 1998-11-17
Abstract: The machine of the invention comprises downstream a squeezing device defining portions (P), successive pairs of first and second plates (1), 1') disposed parallel inside which the portions (P) are engaged. The first and second plates (1, 1') of each pair move forward in the machine by keeping their spacing and remaining longitudinally in coincidence, whilst moving transversally at the same speed but in opposite directions so as to make the portion (P) they enclose rotate. Secondly, the transversal movement directions are alternate between the first successive plates (1) and between the successive second plates (1'). Consequently, the continuous filled-up casing (B) driven by the pairs (1, 1') advances inside the machine in the form of successive portions (P) between which a twist is formed.
