Patent CA-2007165-C (CA)
Inventor: SCHERER RICHARD J
IPC: H01R4/24
Filed: 1990-01-04
Granted: 2001-04-10
Abstract: In electrical terminals it is sometimes necessary to insert two wires into a contact adapted for insulation displacement connection and to do so successfully the wires must enter the wire receiving slot sequentially. A wire receiving opening aligned with the wire receiving slot should have a generally circular opening to readily receive the wires but when the wires are forced in the direction of the wire receiving slot a semi-circular concavity communicating with the opening and positioned on the side of the opening opposite the slot will receive one wire to feed the wires sequentially.

Granted: 1995-06-20
Abstract: A water filter cartridge has a cylindrical shell. A conduit runs between closing end walls and is disposed within a filtration material.  There are additional openings in the respective end walls for communicating the flow of water through the material. A water filtration element of a porous medium is shaped to nest within a portion of the shell encircling a corresponding portion of the filtration material and defining space between the medium and the inner side wall of the shell with that space being in the water flow path from one of the end walls and the material through the medium.  A reference color is exhibited over a portion of the exterior side wall of the shell adjacent to the location of the medium inside the shell, and the medium exhibits a given color upon beginning of usage but changes color with continued usage in response to its entrapment of matter in the water.  The shell is transparent over the medium to enable the user to compare the medium color to the reference color.  The filtration material is secured in place by a plug forming one of the end walls and which has an opening around its periphery with a water pervious ring being sandwiched between that peripheral opening and the space defined on the outside of the filtration medium.

Title: Wire harness protector and pivotable door assembly including same
Inventor: MARKS LARRY DEAN
IPC: H02G3/04
Filed: 1990-08-08
Granted: 1996-05-28
Abstract: A wire harness protector for use in an appliance.  The wire harness protector consists of two members.  A first member is secured to the door so as to pivot therewith.  A second member is also secured to the door but remains stationary when the door is pivoted.  Thus, when the door is pivoted, the second member is fixed relative to the door support structure and the first member pivots with the door.          Both the first member and the second member include conduits which are aligned with the hinge axis of the door.  Each of the first and second members forms an enclosure for enclosing and routing the wire harness.  The conduits are formed by U-shaped channels and covers therefor.  The covers are held in place by means of locking snaps.  The entire first and second members may each be formed in a single integral molding process from a thermoplastic material such as a fire retardant polypropylene.  In an alternative embodiment, the first member may be formed of a shallow U-shaped channel and the wire harness may be secured inside the channel by means of adhesive tape so that the wires are secured in predetermined positions within the U-shaped channel.

Title: Optical analytical instrument and method
Inventor: SAYEGH EMILE
IPC: G01N21/53
Filed: 1991-10-11
Granted: 1996-06-25
Abstract: Optical analytical instruments to determine a physical parameter of a fluid, and methods of operation of such instruments, are shown.  These employ a source of suitable optical radiation, a detector means, means defining a zone for the fluid, means defining an optical path from the radiation source through the fluid zone to the detector means, and reading and control circuitry.  At least two readings of optical energy that has been influenced by the fluid are taken without there having occurred substantial change to the fluid.  During one of the readings a filter of known absorbance is included in the optical path so that the respective reading represents a calibration reading.  A calibration-value-determining means is constructed first to compare, effectively, the two readings to remove the effect of the fluid from the value of the calibration reading, second, to compare, effectively the residual value of the calibration reading to a known value based on the known absorbance of the filter, and, third, on the basis of the second comparison, to make a calibration adjustment based on values derived while the fluid sample remained unchanged in the fluid zone.  Novel software implementations of the determinations are shown.  Specific examples of instruments and methods implementing these features shown are a dual lamp, no-moving part in-line spectrophotometer, a no-moving part reflection colorimeter capable of on-line or off-line operation, a scatter or fluorescence detecting implementation and a turbidimeter.

Title: Light-wave distance measuring apparatus for vehicle
Inventor: TANABE TORU
IPC: G01S17/931
Filed: 1992-03-11
Granted: 1997-09-23
Abstract: A  light-wave  distance  measuring  apparatus  has  an intermittent control continuously changing periods of time during which a light intensity modulator 1 transmits and interrupts transmitting a light intensity modulated signal so as to avoid a synchronization of the light intensity modulated signal  of  the  present  apparatus  and  a  light  intensity modulated signal from a second light-wave distance measuring apparatus. The operation of the intermittent control prevents a misfunction of the apparatus. Provisions of a self-speed detector,  a time marker and a light transmission interval measurer enable the apparatus to detect the speed of a target object. Thus, the apparatus is suitable as a vehicle mount type. The apparatus accurately operates even when both the apparatus and the target object are moving. The apparatus also accurately  operates  without  an  interference  even  when corresponding light-wave distance measuring apparatus  for vehicle are used in a small area.
