Abstract
Abstract Integrated circuits (IC's) are stored for a time interval in a set of elongated guideways to bring them to a preselected temperature prior to testing. The guideways each hold a line of IC's in a loose end-to-end array. A frame carries the guideways. The frame and guideways rotate about a central shaft that is generally aligned with the guideways. The guideways are rotatably mounted in the frame and a gear system, preferably one carried on the frame and the guideways, ensures that as the frame rotates the guideways maintain the same angular orientation with respect to the horizontal. In the preferred form the guideways are generally tubular members with an upwardly facing open channel and an opposed, spaced apart rail that retain and guide the IC's. The entire frame and the guideways carried in the frame are inclined from the horizontal to provide a gravity feed of the IC's from one of the guideways located at an "unloading" position.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
174 words
Storage means for a tester of integrated circuits comprising, a set of elongated guideways that can each hold a plurality of integrated circuits in a relatively loose, end-to-end abutting alignment, a frame that carries said guideways, said frame having a central axis of rotation and said guideways being arrayed about said axis of rotation, wherein said guideways are each rotatable with respect to said frame about their own longitudinal axis, means rotating said frame in a step-wise manner about said axis of rotation through a preselected number of angular positions that include a load position where integrate circuits can be loaded into one of said guideways and a feed position where integrated circuits are discharged from of said guideways, and means maintaining said guideways at a substantially constant angular orientation with respect to the horizontal as said frame rotates through said angular positions, wherein said central axis and said guideways are inclined with respect to the horizontal so that integrated circuits are loaded into and fed from said guideways using the force of gravity
Claim 2
Dependent Claim
174 words
Storage means for a tester of integrated circuits comprising, a set of elongated guideways that can each hold a plurality of integrated circuits in a relatively loose, end-to-end abutting alignment, a frame that carries said guideways, said frame having a central axis of rotation and said guideways being arrayed about said axis of rotation, wherein said guideways are each rotatable with respect to said frame about their own longitudinal axis, means rotating said frame in a step-wise manner about said axis of rotation through a preselected number of angular positions that include a load position where integrate circuits can be loaded into one of said guideways and a feed position where integrated circuits are discharged from of said guideways, and means maintaining said guideways at a substantially constant angular orientation with respect to the horizontal as said frame rotates through said angular positions, wherein said central axis and said guideways are inclined with respect to the horizontal so that integrated circuits are loaded into and fed from said guideways using the force of gravity
Claim 3
Dependent Claim
47 words
The storage means according to claim 1 wherein said guideways are each rotatable with respect to said frame about their own longitudinal axis and wherein said orientation maintaining means comprises gear means that engages each of said guideways and controls its angular orientation about its longitudinal axis.
Claim 4
Dependent Claim
33 words
The storage means according to claims 1, or 2 wherein said frame includes a central shaft about which said frame rotates and a pair of end plates mounted transversely on said central shaft.
Claim 5
Dependent Claim
49 words
The storage means according to claim 2 wherein said gear means includes at least one gear secured on said shaft near one of said end plates and a set of planetary idler gears mounted for free rotation on said end plates and each engaged to said shaft mounted gear.
Claim 6
Dependent Claim
55 words
The storage means according to claim 4 wherein said gear means further includes a guideway gears secured to the ends of said guideways and engaged with an associated one of said idler gears whereby said rotation of said frame causes a rotation of said idler and guideway gears to provide said substantially constant angular orientation.
Claim 7
Dependent Claim
44 words
The storage means according to claim 3 further comprising a housing that encloses said frame and said guideways, said housing including a pair of spaced apart mounting brackets, and wherein said central shaft has end portions that are replaceably received in said mounting brackets.

Dependent Claim
26 words
The storage means according to claims 1, or 2 wherein each of said guideways include an upwardly facing open channel that stores and guides integrated circuits.
Claim 10
Dependent Claim
44 words
The storage means according to claim 8 wherein each of said guideways further include a rail member that opposes and is spaced apart from said channel to provide further control and guidance over the orientation and movement of said integrated circuits in said guideways.
Claim 11
Dependent Claim
25 words
The storage means according to claim 9 wherein each of said guideways further comprises an elongated member that supports said rail member and said channel.
Claim 12
Dependent Claim
17 words
