A pair of actuator units each has one end pivotally attached to the elongated beam and the other end pivotally attached respectively to the pair of guide arm units.  The pair of actuator units respectively move the pair of guide arm units toward and away from each other about their corresponding ends.  A controller is connected to the pair of actuator units for operating the same to move the pair of guide arm units toward and away from each other.
Patent CA-2012055-C (CA)
Inventor: DETWEILER CHARLES ABRAHAM
IPC: E05B65/12
Filed: 1990-03-13
Granted: 1996-02-27
Abstract: An improved deck lid lock with remote release for motor vehicles.  The deck  lid  lock  employs  a  solenoid  operated axially  movable  armature  which  is  directly  coupled  to  a rotatable lever.  The lever is normally biased to a latched position.  The lever is lockingly engageable with a rotatable pawl which is normally biased to a latched position.  The pawl engages a pair of rotatable, asymmetrically oriented striker cams which are normally biased to an unlatched position.  The striker cams define a cavity for engaging a striker.  Upon energization of the solenoid, the armature is attracted to the solenoid causing it to rotate the lever so as to disengage the pawl.   The normal biasing of the striker cams overcome the biasing  of  the  pawl  to  rotate  the  striker cams  to  the unlatched position thereby opening the deck lid.   When the deck lid is closed, contact with the striker over-rotates the striker  cams  permitting  the  pawl  to  rotate  to  a  latched position thereby lockingly engaging the lever.  The deck lid lock further incluees a rotatable key cam which acts on the lever to enable release of the deck lid through conventional manual key actuations.  Improved electrical switch means are provided for signaling when the deck lid is open.

Title: Radio telecommunication apparatus
Inventor: HATTORI KIYOSHI
IPC: H04M1/724
Filed: 1991-01-14
Granted: 1995-08-29
Abstract: The cellular mobile telephone apparatus comprises a radio unit having an antenna, and a telephone unit which is connected to the radio unit via a line and is formed of a main unit and handset.  To originate a call, a user dials the telephone number of an other party to be called.  When the dialing is detected, a calling tone indicating to the user that the call being originated is gen-erated from a speaker of the telephone unit.  To start speech communication, it is necessary to designate and capture a speech channel in the radio channel.  When the capture of the designated speech channel is detected, the calling tone is stopped.  After the communication, there are three types of terminating the call.  At the end of communication, the type of the termination is detected and the corresponding synthesized voice message is generated.

Title: Optical branching waveguide
Inventor: KOREN UZIEL
IPC: G02B6/122
Filed: 1991-04-29
Granted: 1998-12-08
Abstract: An optical branching waveguide having low radiative loss and low back-reflectivity is described.  By employing between the branches a region having a gradual decrease in effective refractive index along the direction of optical propagation, the deleterious effect of wedge tip truncation can be reduced. According to the teachings of the invention, this may be accomplished by gradually decreasing the thickness of the optical material along the axis of optical propagation and planarizing the region with an optical material having an lower refractive index than the underlying optical material.

Granted: 2003-07-01
Abstract: The present invention is directed to a method of achiev-ing RecA protein facilitated amplification of a double-stranded DNA target sequence having first and second complementary strands, each strand with 5' and 3' ends. The method involves complexing a primer complementary to a 5' end region of the first strand and a primer complementa-ry to a 5' end region of the second strand with RecA pro-tein in the presence of ATP-y-S. The complexed primers are then reacted in a mixture also containing the target se-quence, all four dNTPs, RecA protein and DNA polymerase.      The reaction is conducted below the temperature required for thermal dissociation of the two target strands and continued until a desired degree of amplification of the target sequence is achieved.      The present invention further includes the cloning and identification of the coding sequences for the RecA protein of Thermus aquaticus.

Title: Soft, high oxygen permeability ophthalmic lens
Inventor: NUNEZ IVAN M
IPC: C08G18/65
Filed: 1992-06-11
Granted: 2003-04-29
Abstract: A low water contact lens material having high 0 2 permeability, a lower water content and reduced polymer matrix size provides adequate O2 to the cornea, but does not wick water away from the eye nor allow protein or other tear components to penetrate and deposit in the lens. Such a lens is made by polymerizing and crosslinking a prepolymer which contains a cyclic polyol with polyalkylether segments containing curable segments.      The cyclic polyols consist of alkoxylated glucose or sucrose which are then reacted with an isocyanate to produce an ultraviolet curable prepolymer. The prepolymer is then placed in a mold and polymerized by exposure to ultraviolet light. The free hydroxyl groups of the material react with a highly hydrophilic reagent to form covalent bonds thus making the surface of the material more wettable.

Title: Ratchet operated continuous chain conveyor and storage and retrieval system utilizing a plurality thereof
Inventor: BENSON R BRIAN
IPC: B65G47/26
Filed: 1993-04-08
Granted: 1997-07-22
Abstract: A ratchet driven continuous chain accumulator conveyor and a accumulating and retrieval system utilizing such conveyor is shown. The accumulator conveyor includes a frame having a pair of continuous chains. The chains are mounted on sprockets on either end of the accumulating conveyors and run in upper and lower chain channels. A hydraulic drive cylinder is supported by the frame of each accumulating conveyor and includes gravity dogs on an operable piston end thereof. The gravity dogs provide for imparting a ratcheting motion to each pair of chains through extension and retraction of the drive cylinder. Each accumulating conveyor includes a plurality of lift means along the length thereof for lifting cases from contact with the driving chains for relieving weight pressure thereon. The accumulating and retrieval includes a computer control and loading mechanisms for automatically loading the accumulator conveyors with product. Some of the accumulating conveyors include automatic discharge means at their discharge ends and the remainder of the accumulating conveyors do not have such automatic mechanisms and are unloaded manually. The conveyors having automatic discharge ends include a further cylinder for pushing individual stacks of product onto an out-feed conveyor running directly adjacent and perpendicular to the out-feed ends of theaccumulating conveyors. A second out-feed conveyor is spaced from the first out-feed conveyor and runs parallel thereto. The second out-feed conveyor is used for conveying individual cases that have been manually transferred from the manual accumulating conveyors thereto. In this manner, specialty orders of lower volume product can be specifically selected and placed on the second out-feed conveyor. The first out-feed conveyor transports the stacks of cases to an appropriate loading dock area having means for assembling the stacks of cases onto a dolly for facilitating loading onto a truck. The second out-feed conveyor first passes through a stacking machine for stacking the individual cases to a desired height. From the stacking machine, the stacked cases then are directed by conveyor means to a loading dock area for assembly onto a dolly.
