Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 154 words
A washing machine for electronic components disposed in a package, comprising; a circular tray rotatable about an axis inclined at 45° to the horizontal, whereby said tray has a surface lying at an angle of 45° to the horizontal, said tray supporting on said surface at least one package to be washed, so that said package orbits said axis; and a plurality of nozzles having horizontal axes and disposed in an array around the center of said tray within the horizontally projected outline of said tray for training respective jets of liquid at different points at different quadrants around said tray, whereby upon rotation of said tray, said package passes through each of the respective jets to be washed, with the angle at which each jet is trained upon said package varying as the package passes therethrough, and the angle with which each jet is trained upon said package differing from jet to jet.
Claim 2
Dependent Claim 154 words
A washing machine for electronic components disposed in a package, comprising; a circular tray rotatable about an axis inclined at 45° to the horizontal, whereby said tray has a surface lying at an angle of 45° to the horizontal, said tray supporting on said surface at least one package to be washed, so that said package orbits said axis; and a plurality of nozzles having horizontal axes and disposed in an array around the center of said tray within the horizontally projected outline of said tray for training respective jets of liquid at different points at different quadrants around said tray, whereby upon rotation of said tray, said package passes through each of the respective jets to be washed, with the angle at which each jet is trained upon said package varying as the package passes therethrough, and the angle with which each jet is trained upon said package differing from jet to jet.
Claim 3
Dependent Claim 20 words
A washing machine according to claim 1, wherein the tray is provided with means for supporting a plurality of packages.
Claim 4
Dependent Claim 21 words
A washing machine according to claim 2, wherein the tray is provided with means for supporting between four and twelve packages.
Claim 5
Dependent Claim 19 words
A washing machine according to claim 2, wherein the number of packages is equal to the number of nozzles.
Claim 6
Dependent Claim 16 words
A washing machine according to claim 2, wherein the packages are identically disposed on the tray.
Claim 7
Dependent Claim 19 words
A washing machine according to claim 5, wherein the packages are disposed at equal angle spacing around the tray.
Claim 8
Dependent Claim 34 words
A washing machine according to claim 6 wherein the packages are of rectangular configuration, their side faces being inclined at 45° to the horizontal at a plurality of points upon rotation of the tray.
Claim 9
Dependent Claim 19 words
A washing machine according to claim 1, wherein the tray is above a tank for recovering the washing liquid.
Claim 10
Dependent Claim 21 words
A washing machine according to claim 1, which further comprises gas projection nozzles trained at said tray for drying said package.
Claim 11
Dependent Claim 20 words
A washing machine according to claim 9, wherein a respective gas projection nozzle is associated with each liquid projection nozzle.
