Patent CA-2024303-A1 (CA)
Inventor: DE JONG HENDRIK J
IPC: A61M36/02
Filed: 1990-08-30
Abstract: Title: Implanter ABSTRACT     The invention relates to an implanter for implanting an implant in an animate being, comprising a housing mounting one end of a hollow injection needle and further a plunger adapted to extend into the hollow needle from the end of the hollow injection needle that is turned towards the housing. According to the invention it is characterized by locking means for retaining the plunger against the pressure of spring means in a position where the plunger extends into the hollow needle over a predetermined distance. The locking means comprise unlocking means which abut the body of the animate being when the injection needle has been introduced into the body to a predetermined depth and subsequently automatically unlock the locking means. This causes the plunger to be pressed by said spring means against an implant disposed in operation in the injection needle for retaining the implant when the injection needle is being retracted from the body.    The invention also relates to a loading device to be used with an implanter according to the invention.

Patent CA-2034487-A1 (CA)
Inventor: LAWLIS VIRGIL B
IPC: C07K19/00
Filed: 1990-06-14
Abstract: The invention includes novel fusion DNA sequences encoding fusion polypeptides which when expressed in a filamentous fungus result in the expression of fusion polypeptides which when secreted result in increased levels of secretion of the desired polypeptide as compared to the expression and secretion of such polypeptides from filamentous fungi transformed with previously used DNA sequences. The fusion DNA sequences comprise from the 5' terminus four DNA sequences which encode a fusion polypeptide comprising, from the amino to carbonyl-terminus, first, second, third and fourth amino acid sequences. The first DNA sequence encodes a signal peptide functional as a secretory sequence in a first filamentous fungus. The second DNA sequence encodes a secreted polypeptide or portion thereof which is normally secreted from the same filamentous fungus or a second filamentous fungus. The third DNA sequence encodes a cleavable linker polypeptide while the fourth DNA sequence encodes a desired polypeptide.      When the fusion DNA sequence is expressed either in the first or second filamentous fungus, increased secretion of the desired polypeptide is obtained as compared to that which is obtained when the desired polypeptide is expressed from DNA sequences encoding a fusion polypeptide which does not contain the second polypeptide normally secreted from either of the filamentous fungi.

Title: Push button switch with lens cap
Inventor: MARTIN ADOLF H
IPC: H01H13/02
Filed: 1991-01-31
Abstract: ABSTRACT OF THE DISCLOSURE    A push button switch has an electrical contact module, an enlarged halo for retaining a switch actuator and a legend plate, and a halo adapter for attaching the halo to the electrical contact module.  The halo and the halo adapter define a housing for the switch actuator which actuator has legs extending through the halo adapter for engaging a spring biased contact carrier in the electrical contact module.  The contact carrier pushes the switch actuator against a first protection formed on the halo.  An actuating force applied to a lens cap of the actuator overcomes the bias of the contact barrier causing the switch actuator to travel inside the housing and come to rest against a wall of the halo adapter to prevent excess pressure on the carrier.

Patent CA-2039797-A1 (CA)
Title: Fiber optic switch
Inventor: CHINN STEPHEN R
IPC: G02F1/313
Filed: 1991-04-04
Abstract: FIBER OPTIC SWITCH              ABSTRACT OF THE DISCLOSURE    The invention relates to an electrically operated fiber optical switch for circularly polarized light.          The switch comprises an input 3-dB fiber optic coupler, a Faraday effect fiber optic phase rotator and an output 3-dB fiber optic coupler, all three providing dual fiber optic paths.  The input 3-dB coupler divides the light waves between two oppositely wound optical fibers in the Faraday effect phase rotator.   The magnetic fields in the phase rotator are adjusted to produce the desired (e.g. ?.pi./2 radians) relative phase delays between the divided light waves, the sign of the relative phase being dependent on current direction.          When the light waves are recombined in the output 3-dB couplers, cancellation will occur in one or the other output fiber as a function of the direction of the magnetic field.  The arrangement provides rapid switch operation by reversing the current direction in a magnetic field producing winding.   The optical switching occurs in an all fiber system, avoiding the losses present in transitions to non-fiber wave tranmission paths.

Abstract: PEDESTRIAN TRAFFIC SIGNAL HEAD            Abstract of the Disclosure The housing of a pedestrian traffic signal head includes an open front and two opposite sides, a first pair of bosses with hinge-pin-receiving passages formed on one side of the housing, a second pair of bosses with hinge-pin-receiving passages formed on the top of the open front, and a third pair of bosses with hinge-pin-receiving passages formed on the bottom of the open front.  A lens door having a fourth pair of bosses with hinge-pin-receiving passages on its top covers the open front of the housing.  A pair of removable hinge pins connect the second or third pair of bosses, depending upon whether the housing is right-hand or left-hand mounted, to the fourth pair of bosses to permit the door to pivot downwardly to open, irrespective of the side of the pole on which the housing is mounted.   The housing and the  lens door cooperate to capture the removable hinge pins when the door is pivoted closed and to free the removably hinge pins when the door is pivoted open.  A single-piece, side-mounted bracket attaches directly to the housing.  A pair of hinge pins are formed on the bracket to removably and pivotally connect either side of the housing  to the bracket.  The bracket has a cavity in which a terminal block resides for making the electrical connection between wiring of the post and wiring of the pedestrian traffic signal head.  The bracket has hinge pins that are directly attached to side bosses. The side bosses are cast as part of the housing in a one-piece construction.  A sunscreen having a unique grate design is disposed over the front of the lens. The grate consists of a lattice formed from zigzagging rows of interconnected strips, with pointed corners along one side and truncated corners along the other side.  Adjacent rows of the strips are aligned so that the truncated corners of one row are interconnected to the pointed corners of the adjacent row.
