Abstract
Abstract There is disclosed a wedge set comprising a wedge block containing a slot with a movable wedge slidable within the slot leaving a space between the movable wedge and the juxtaposed wall of the wedge block. A screw shaft is threaded to the wedge block and to the movable wedge so that rotation of the screw slides the wedge relative to the block causing the said space to enlarge or decrease. A module plate or the like fitted in the space can thus be clamped by tightening the screw. The clamping is with very great pressure so that when the module plate becomes heated the heat is readily and efficiently conducted to and through the wedge block from where it can be dissipated in a heat sink, or transferred into a heat exchanger for disposition by other means such as waste water and the like.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
184 words
Mounting means for clamping, and conducting heat from, a panel adapted to be mounted therein comprising: a wedge block having a slot with a base and first and second converging sides, within the block, a movable wedge having first and second converging sides, placed within the slot, the first side of the wedge being in contact with the first side of the slot and the second side of said wedge being juxtaposed and parallel to, and leaving a space from, the second side of said slot, whereby an edge of said panel may be plugged into said space, a shaft, means rotatably attaching a first end of said shaft to one end of said wedge and means rotatably attaching the second end of said shaft to the opposite end of said block, thereby permitting sliding of said wedge along said slot while said first sides remain in contact with each other and corresponding change of the dimension across said space and clamping of the plugged-in part of the panel between the second surface of the wedge and the second surface of the wedge block.
Claim 2
Dependent Claim
184 words

Claim 3
Dependent Claim
52 words
Mounting means according to claim 1 in which the second side of said wedge contains a first registration means and the adjacent side surface of said panel within said space contains a second registration means which registers with the first registration means and prevents relative sliding between the wedge and the panel.
Claim 4
Dependent Claim
26 words
Mounting means according to claim 1 in which said shaft is flexible so that it bends resiliently when the wedge slides relative to the wedge block.
Claim 5
Dependent Claim
43 words
Mounting means according to claim 1 in which the means rotatably attaching the first end of said shaft to one end of said wedge comprises threads at said first end of said shaft and corresponding threads on said one end of said wedge.
Claim 6
Dependent Claim
43 words
Mounting means according to claim 4 in which the means attaching the second end of said shaft to said opposite end of said block comprises threads at said second end of said shaft and corresponding threads on said opposite end of said block.
Claim 7
Dependent Claim
39 words
Mounting means according to claim 1 in which each of said sides is straight and said one end of said wedge has a greater transverse dimension than its other end, and said shaft extends substantially parallel to said slot.
Claim 8
Dependent Claim
41 words
Mounting means according to claim 6 in which each of said first sides contains a longitudinal groove for a distance along its length, said grooves being juxtaposed and in communication with each other thereby providing a cavity which accommodates said shaft.
Claim 9
Dependent Claim
99 words
Mounting means according to claim 1 in which the means rotatably attaching a first end of said shaft to one end of said wedge comprises a pin rotatably mounted to said wedge and provided with threads, the first end of said shaft being provided with threads engaging those of said pin, and the means rotatably attaching the second end of said shaft to the opposite end of said block comprises a second pin rotatably mounted in the block and provided with threads, said second end of said shaft being provided with threads corresponding to those of the second pin.
Claim 10
Dependent Claim
23 words
Mounting means according to claim 5 in which the threads at said first and second ends have the same direction but different pitches.
Claim 11
Dependent Claim
29 words
Mounting means according to claim 9 in which the pitches of the threads at the two ends are such that the movable wedge moves relative to the wedge block.
Claim 12
Dependent Claim
28 words
Mounting means according to claim 3 in which the flexible shaft has a resilient bias tending to hold the movable wedge against the base of the wedge block.
Claim 13
Dependent Claim
34 words
Mounting means according to claim 1 in which a heat sink is connected to the wedge block so that heat is readily conducted from the panel through the wedge block to the heat sink.
