Abstract
Abstract The invention provides apparatus to inspect the colored insulation on wires placed in equipment to add contacts or to mould a termination on the wires. The apparatus ensures that the correct color relationships are present before crimping or moulding and disarms the equipment until this correct relationship is established. The equipment can be operated only after the relationship has been established.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
Apparatus for use with a machine used to perform an operation on ends of cables, each of the cables having a plurality of wires coded individually in differently coloured insulation, and each of the wires being intended for location at discrete sites in the machine prior to the operation, the apparatus comprising; a colour responsive camera focused to create an electronic image of the coloured insulations when the wires are on the sites and in place for the operation; memory means containing first information corresponding to the colours and locations of the insulations when these insulations are positioned correctly in the machine; comparator means receiving the electronic image and converting the image into second information including means comparing the first and second informations to create a first signal indicating that the informations correspond; and means coupled to the machine to render the machine inoperable in the absence of said signal and to permit normal operator use of the moulding machine on receiving said signal.
Claim 2
Dependent Claim
164 words
Apparatus for use with a machine used to perform an operation on ends of cables, each of the cables having a plurality of wires coded individually in differently coloured insulation, and each of the wires being intended for location at discrete sites in the machine prior to the operation, the apparatus comprising; a colour responsive camera focused to create an electronic image of the coloured insulations when the wires are on the sites and in place for the operation; memory means containing first information corresponding to the colours and locations of the insulations when these insulations are positioned correctly in the machine; comparator means receiving the electronic image and converting the image into second information including means comparing the first and second informations to create a first signal indicating that the informations correspond; and means coupled to the machine to render the machine inoperable in the absence of said signal and to permit normal operator use of the moulding machine on receiving said signal.
Claim 3
Dependent Claim
52 words
Apparatus as claimed in claim 1 in which the comparator means creates a second signal when the informations do not correspond and in which the comparator means further includes identifying means which, upon receiving the second signal, compares the second information with further information to identify the colour of the wire insulation.
Claim 4
Dependent Claim
32 words
Apparatus as claimed in claim 2 and further including error indicating means receiving information from the identifying means to show the error in the colours of the wire insulations at the sites.
Claim 5
Independent Claim
140 words
A method of recognizing an error in an array of wires each of which has a differently coloured insulation, the method comprising the steps: placing wires on sites in the required placement and colour arrangement; recording the placing and colour arrangement using a colour video camera and digitizer in the form of a digital first information; replacing the wires with new wires to be tested at the sites; viewing the new wires with the video camera and digitizing the picture information with respect both to placement and colour of the insulation on the wires; and comparing said first information with the picture information and creating either a first signal indicating that the new wires are positioned and arranged correctly, or a second signal indicating an error in the colour of the insulation appearing at at least one of the sites.
Claim 6
Independent Claim
140 words
A method of recognizing an error in an array of wires each of which has a differently coloured insulation, the method comprising the steps: placing wires on sites in the required placement and colour arrangement; recording the placing and colour arrangement using a colour video camera and digitizer in the form of a digital first information; replacing the wires with new wires to be tested at the sites; viewing the new wires with the video camera and digitizing the picture information with respect both to placement and colour of the insulation on the wires; and comparing said first information with the picture information and creating either a first signal indicating that the new wires are positioned and arranged correctly, or a second signal indicating an error in the colour of the insulation appearing at at least one of the sites.
Claim 7
Dependent Claim
57 words
A method as claimed in claim 4 and further comprising the steps; receiving a second signal to trigger the following steps; comparing the picture information with respect to colour with stored information to identify the colour; and creating an error signal to show the colour appearing incorrectly at a site and the site where this colour appears.
