Patent CA-2160476-A1 (CA)
Inventor: VAN DEN BRINK HANS GERARD
IPC: H05K13/08
Filed: 1994-04-14
Abstract: The invention relates to a simple and economic optical system for mutually po-sitioning SMD components having con-necting leads and the corresponding pads on pad carrying members with the object of bringing the connecting leads and pads together in one plane through translation or rotation, of positioning them and fix-ing them. The optical system utilizes a beam splitter, so that it is possible to ob-serve simultaneously with the human eye the spaces in front of and behind the beam splitter. For considerations of robustness the semi transparent mirror used to this end is evaporated on a transparent substrate which has a finite thickness. A substrate having finite thickness leads to an appar-ent displacement of the space behind the substrate relative to the space in front of the substrate. The invention relates to the compensation of this displacement by the installation of a compensation plate hav-ing identical optical properties in the space over the semi transparent mirror on the sub-strate. The semi transparent mirror is in-serted between two optically identical flat substrates.

Patent CA-2182929-A1 (CA)
Inventor: CORVIN JOHN H
IPC: B60M1/14
Filed: 1996-08-08
Abstract: A power controlling unit for use with a radio board of a trolley pole switch controller is disclosed.  The trolley pole switch has at least one frog for switching the path of travel that  an  energy  collector  takes  through  a  junction  of catenaries.    The  power  controlling  unit  includes  three reduction stages,  a chopper control stage,  and two output stages.  A first reduction stage reduces power received from one catenary to an initial power level.  The chopper control stage outputs two pairs of alternating signals. Controlled by a first pair of alternating signals, a second reduction stage reduces the initial power level to a secondary power level to operate the radio board.  As long as it receives the initial power level, the third reduction stage reduces the secondary power level to a primary power level to operate the power controlling unit.  Controlled by a second pair of alternating signals and the initial power level, when a turn output stage receives a turn command from the radio board, it switches power from one catenary to a turn solenoid of such frog thereby switching the path of travel that the energy collector will take to a turn catenary.   Controlled by the second pair of signals and the initial power level, when a straight output stage receives a straight command from the radio board,  it switches power from one catenary to a straight solenoid of such frog thereby switching the path of travel that the energy collector will take to a straight catenary.
