Abstract
Abstract The apparatus for treating small items is provided with a workbench surface which is supplied with air from above from a flow space and which is sealingly surrounded by a double-wall housing. The housing forms continuously extending flow cross-sections at edges of the surface. Disposed in front of the housing wall is a partition which defines therewith the flow cross-sections and forms in the interior of the housing a deflection edge at a spacing from the workbench surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
An apparatus for treating items in a controlled environment comprising: a housing having longitudinal sidewalls defining a flow space means, said longitudinal sidewall means having vertically disposed air passage means; a horizontal bench plate surface for supporting said items disposed in said housing, said horizontal bench plate surface having edges which contact said longitudinal sidewall means and said vertically disposed air passage means; means for feeding air from above said horizontal bench plate surface such that said air impinges on said horizontal bench plate surface is deflected by said horizontal bench plate surface toward said longitudinal sidewall means and carried away by said air passage means.
Claim 2
Independent Claim
106 words
An apparatus for treating items in a controlled environment comprising: a housing having longitudinal sidewalls defining a flow space means, said longitudinal sidewall means having vertically disposed air passage means; a horizontal bench plate surface for supporting said items disposed in said housing, said horizontal bench plate surface having edges which contact said longitudinal sidewall means and said vertically disposed air passage means; means for feeding air from above said horizontal bench plate surface such that said air impinges on said horizontal bench plate surface is deflected by said horizontal bench plate surface toward said longitudinal sidewall means and carried away by said air passage means.
Claim 3
Dependent Claim
27 words
An apparatus according to claim 1 including a partition disposed in front of the longitudinal sidewall means of the housing which defines therewith the air passage means.
Claim 4
Dependent Claim
42 words
An apparatus according to claim 2 wherein the partition extends from the longitudinal sidewall means into the interior of the housing and includes a deflection edge at the horizontal bench plate surface which forms therewith a gap for receiving the deflected air.
Claim 5
Dependent Claim
23 words
An apparatus according to claim 3 including means for adjusting the deflection edge vertically so as to control the size of the gap.
Claim 6
Dependent Claim
19 words
An apparatus according to claim 1 wherein the horizontal bench plate surface is surrounded by the air passage means.
Claim 7
Dependent Claim
34 words
An apparatus according to claim 1 wherein said means for feeding air includes a fan arranged upstream of the flow space, the fan being disposed in a fan housing mounted above the flow space.
Claim 8
Dependent Claim
22 words
An apparatus according to claim 6 wherein the fan is connected to a head space provided with air accesses for conditioning inserts.
Claim 9
Dependent Claim
16 words
An apparatus according to claim 6 wherein a fan device is disposed between adjacent fan housings.
Claim 10
Dependent Claim
30 words
An apparatus according to claim 2 wherein the housing is provided at its longitudinal sidewall means with at least one viewing window and manipulation means pass through the viewing window.
Claim 11
Dependent Claim
17 words
An apparatus according to claim 1 wherein the horizontal bench plate surface is provided with conveyor elements.
