Abstract
Abstract A control panel for use with a pneumatic control system has a plurality of openings on one face of the panel positioned relative to guide means on the panel so that an operator can temporarily cover up the openings by sliding a closure member, guided by the guide means, over the face of the panel to cover up in turn the openings beneath the path of travel of the closure member. The member is conveniently the operator''s finger. By closing the openings, pneumatically operable switching components forming part of the control system are actuated. The components are pneumatically connected to the openings on the panel at a postiion away from the face of the panel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A control panel for use with a pneumatic control system, the panel having a plurality of openings provided on one face and positioned relative to guide means on the panel such that an operator, by sliding a closure member over the face of the panel, with the member guided and restrained by the guide means but free to slide over the face of the panel along a path which passes over said openings in turn, temporarily covers up the openings positioned beneath the path of travel of the closure member to thereby actuate pneumatically operable switching components forming part of the control system and pneumatically connectable to the openings at a position away from the face.
Claim 2
Dependent Claim
116 words
A control panel for use with a pneumatic control system, the panel having a plurality of openings provided on one face and positioned relative to guide means on the panel such that an operator, by sliding a closure member over the face of the panel, with the member guided and restrained by the guide means but free to slide over the face of the panel along a path which passes over said openings in turn, temporarily covers up the openings positioned beneath the path of travel of the closure member to thereby actuate pneumatically operable switching components forming part of the control system and pneumatically connectable to the openings at a position away from the face.
Claim 3
Dependent Claim
39 words
A control panel as claimed in claim 1 in which the openings are arranged in a horizontal row or vertical column and a plurality of such rows or columns of openings, each with its own guide means, are provided.
Claim 4
Dependent Claim
17 words
A control panel as claimed in claim 1 in which said closure member is the operator''s finger.
Claim 5
Dependent Claim
38 words
A control panel as claimed in claim 3 in which the guide means for the operator''s finger is in the form of a shallow groove in the face of the panel with the openings leading into the groove.
Claim 6
Dependent Claim
94 words
A control panel as claimed in claim 3 in which the guide means for the operator''s finger comprises a rib projecting from the face of the panel and positioned a short distance away from the openings. 6 A control panel as claimed in claim 3 in which the guide means for the operator''s finger comprises a pair of parallel ribs projecting from the face of the panel with the ribs spaced apart by a distance slightly greater than the thickness of a finger and with the openings extending to the panel between the ribs.
Claim 7
Dependent Claim
63 words
A control panel as claimed in claim 3 in which each opening has a pad associated therewith, the pad being biassed to a position in which the openings are not covered by the pads and arranged such that the operator''s finger by sliding over the pads displaces them into a position in which they temporarily close the opening with which they are associated.
Claim 8
Dependent Claim
40 words
A control panel as claimed in claim 1 in combination with a control system having a plurality of pneumatically operable switching components, the components being pneumatically connected to the openings at a position away from the face of the panel.
