Patent CA-2066565-A1 (CA)
Title: Apparatus for compacting scrap metal
Inventor: CACACE ANTONINO G
IPC: B30B15/02
Filed: 1990-09-19
Abstract: Apparatus for compacting swarf to form a billet for subsequent hot working is disclosed. The apparatus includes a die (70) comprising a number of portions (80) defining a cavity (78) for holding a tube in which the swarf is compacted by one or more rams (20). The die portions are surrounded by one or more sleeves (72) which hold them together. The sleeves can be moved in the axial direction to allow the die portions to be separated in the radial direction to release the billet. The sleeves are slidably mount-ed in a housing (74) and are moved apart axially by jacks (108). The outer face of the die and the sleeves are complementally tap-ered to assist release of the sleeves. Charge boxes (16) are provided at each end of the die and swarf is fed from the charge boxes by the rams (20) into both ends of the cavity (78). The die and housing are mounted on a pedestal (116) so as to pivot into axial alignment with mechanisms (118, 120) which grip the ends of the die portions and separate them radially to release the billet. An empty tube can be fed into the die cavity through the mechanism (120) and the billet can be fed through the mechanism (118) af-ter it has been ejected from the die cavity.

Title: Regulateur d'intensite a double shunt
Inventor: HAUN ANDY A
IPC: H02H1/06
Filed: 1991-07-22
Abstract: Un circuit régulateur de courant destiné à dériver un surplus de courant d'une alimentation de courant (14) utilise deux voies de dérivation séparées (52, 68) selon le niveau de surplus de courant sur la ligne d'alimentation. Le premier circuit de dérivation est activé lorsque le courant dépasse un niveau minimum établi par une diode Zener (50). Le second circuit de dérivation de courant est activé de manière sélective par un circuit de commutation (60) qui compare le courant dans le premier circuit à une tension de référence (58) proportionnelle au courant de ligne. Cet agencement offre un avantage en ce qu'il permet de dériver le surplus de courant sans produire des niveaux importants de chaleur ni affecter les dispositifs de détection de courant.

Patent CA-2087626-A1 (CA)
Inventor: SHEA DONALD F
IPC: G01R29/08
Filed: 1993-01-20
Abstract: The wave type, orientation and rotation of an incident electromagnetic signal  having an unknown polarization is identified through single channel frequency domain signal analysis  of  the  incident  electromagnetic  wave  power  as measured by an orthogonally polarized electromagnetic sensor.          A controlled switch samples the power measurements at each orthogonal output of the sensor to generate a signal comprised of a carrier frequency component and two sideband frequency components  in the  frequency domain.   The  sampled  radio frequency  signal  is  down converted by a  single  channel receiver to an intermediate frequency where the carrier and one sideband frequency component are separated and coherently shifted  to  the  same  frequency.    A  phase  detector and ratiometer  measure  the  relative  phase  and  amplitude differences  between  the  separated  carrier  and  sideband frequency components to identify the wave type, orientation and rotation of the incident electromagnetic signal.

Patent CA-2096296-A1 (CA)
Inventor: NONIS ALBINO D
IPC: E04B2/00
Filed: 1993-05-14
Abstract: An insulating cladding panel for an exterior wall of a building is a sheet of insulating material having a plurality of intersecting channels on its interior surface.  The channels are sized and spaced to provide a rapid equalization of pressure across the panel when installed on the wall.  This pressure equalization essentially eliminates the forces promoting water penetration through the panel joints to the wall.  The channels also facilitate the escape of any water which may penetrate the panel system.  The neutralization of the live wind load by the channel system of the panels eliminates the need for supporting members when installing the panels on a wall.
