Title: Apparatus for cooling heat generating electrical components
Inventor: SIMONS ROBERT EDWARD
IPC: H01L23/373
Filed: 1978-06-06
Abstract: The apparatus comprises integrated circuit chips (10) which are to be cooled. 
     Heat is conducted from the chips (10) to a cold plate (36) by a heat transfer path including spring biased heat conducting members (26) and housing (16). 
     A thermal adapter (42) is sandwiched between the housing (16) and the cold plate (36) and introduces predetermined heat transfer characteristics between the housing and the plate. 
     The adapter can be a good or poor conductor. The adapter can comprise cut-out regions aligned with low powered chips to increase the thermal resistance to heat flow from those chips while the remaining regions, aligned with high powered chips, have a lower thermal resistance. This permits both the low and high powered chips to attain their optimum operating temperature.

Abstract: An electrochromic display device consists of orthogonal electrodes 26,30 on the flat inner faces of a panel. The electrochromic composition in the panel, preferably a pyrazoline, has a threshold potential above which a display effect is achieved at a crossover point of the electrodes. The drive means 58 is of such low impedance and the electrodes are of such low resistance that the voltage levels at display sites (crossovers) are independent of whether or not a display is being effected at a display site. The display effect is temporary and is cyclically regenerated. The time average of voltage signals across unselected display sites is zero. Electrodes 28 consist of tin oxide and a central gold conductor 34 to decrease resistance. Electrodes 30 are of gold.

IPC: B22D11/047
Filed: 1979-11-22
Abstract: A method of cooling a flow of a molten material involves simultaneously subjecting the flow to a stirring action which is such that the temperature of the material is substantially the same at any point in any one plane perpendicular to the direction of flow. The cooling may be applied to a molten material to bring it either closer to its melting point or liquidus temperature or to bring it within its freezing range where this is desired as in, for example, the production of metallic slurries.In apparatus for cooling a flow of a molten material having means for cooling and means for simultaneously stirring the flow, both means preferably comprise at least one element extending transversely within a duct through which the flow is directed. The element, which may be a hollow rod arranged to carry a flow of a coolant, is preferably made of a highly conducting material e.g. graphite or a metal whereas the walls of the duct are preferably of a insulating material. By this means nearly all of the cooling effect can be concentrated In the elements which permits close control over the cooling action. The number, arrangement and size of the elements will depend on the degree of cooling required and on the amount of stirring which is necessary to achieve even cooling along the duct.The cooled flow, after passing through the duct, is conveniently led into a mould or series of moulds or into a casting machine in which solidification to give a shaped article takes place.
