Abstract
Abstract Stop-control apparatus for an organ includes a latching circuit for each stop and an etongate support panel (12) on which modular groups of touch-sensitive switches (50, 52, etc.) are disposed in pairs (50,52) with an indicating lamp (34) disposed between the switches of each pair, wherein the switches of the pair cause the latching circuit to actuate and de-actuate a given stop while the lamp indicates whether the stop is actuated. The touch-sensitive switches are usually overlaid with a flexible front surface layer (16) through which the switches are operable by touch of the layer and through which the indicating lamps are visible only when energised. The lamps extend through holes (18) in the support panel and corresponding holes (58 or 53) in the switch membranes (14), the arrangement being such that either two stops or one stop are controlled in a given column, and the control panel is universal for organs with different stop combinations. The surface layer has printed thereon a plurality of colour- contrasting outlines (60), each positioned to circumscribe a different pair of switches and associated indicating lamp to facilitate stop selection, the surface layer otherwise having a "dead front" appearance.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
277 words
Stop-control apparatus (10, figure 2) for an organ comprising: a plurality of latching circuits (35) associated respectively with individual organ stops (62) and which energise circuitry for affecting the tonal quality of the organ; an elongate panel (12,14) having a multiplicity of apertures (18,58 etc.) theve- through arranged in at least first (20) and second (24) vertically spaced horizontal rows and a plurality of horizontally spaced vertical columns (26,28), the apparatus comprising a plurality of touch-sensitive switches (50,52,50a, etc.) of which at least some are arranged in pairs (50,52; 50a,52a) connected for setting and re-setting a corresponding latching circuit, the switches of each pair being disposed proximate an aperture in the panel and respectively below and above the aperture in the direction of the panel surface; and indicating lamps (34,36) responsive to respective conditions of each of the organ-stop latching circuits for indicating the state of each latching circuit, each lamp (34) being aligned with the aperture (18, 58) in the panel disposed between the pair of touch-sensitive switches (50,52) employed for operating its respective latching circuit; characterised in that the apparatus further includes a common surface layer (16) overlying the elongate panel and providing a substantially flat overall front surface for the panel, the surface layer being so constructed that the switches are operable to set and reset the latching circuits by touching the said surface layer or directly touching switch contacts lying in the surface layer, and'that the indicating lamps are visible through the panel surface layer only when energised, the surface layer having displayed thereon a plurality of outlines (60) each positioned to circumscribe a different pair of switches and their associated indicating lamp.

Stop-control apparatus (10, figure 2) for an organ comprising: a plurality of latching circuits (35) associated respectively with individual organ stops (62) and which energise circuitry for affecting the tonal quality of the organ; an elongate panel (12,14) having a multiplicity of apertures (18,58 etc.) theve- through arranged in at least first (20) and second (24) vertically spaced horizontal rows and a plurality of horizontally spaced vertical columns (26,28), the apparatus comprising a plurality of touch-sensitive switches (50,52,50a, etc.) of which at least some are arranged in pairs (50,52; 50a,52a) connected for setting and re-setting a corresponding latching circuit, the switches of each pair being disposed proximate an aperture in the panel and respectively below and above the aperture in the direction of the panel surface; and indicating lamps (34,36) responsive to respective conditions of each of the organ-stop latching circuits for indicating the state of each latching circuit, each lamp (34) being aligned with the aperture (18, 58) in the panel disposed between the pair of touch-sensitive switches (50,52) employed for operating its respective latching circuit; characterised in that the apparatus further includes a common surface layer (16) overlying the elongate panel and providing a substantially flat overall front surface for the panel, the surface layer being so constructed that the switches are operable to set and reset the latching circuits by touching the said surface layer or directly touching switch contacts lying in the surface layer, and'that the indicating lamps are visible through the panel surface layer only when energised, the surface layer having displayed thereon a plurality of outlines (60) each positioned to circumscribe a different pair of switches and their associated indicating lamp.
Claim 3
Dependent Claim
48 words
Stop-control apparatus according to claim 1, wherein the elongate panel comprises a flat, elongate support panel (12) with a first set of apertures (18), and a flat switch panel (14) containing the plurality of switches and with a secondaset of apertures (58,53) aligned with the first set (18).
Claim 4
Dependent Claim
48 words
Stop-control apparatus according to claim 1 or claim 2, wherein the touch-sensitive switches and corresponding outlines are disposed in groups (70, figure 1) associated with given organ manuals or functions, and the outlines of a group are distinguished by colour from outlines of other groups and the surface.
Claim 5
Dependent Claim

Claim 6
Dependent Claim

Stop-control according to claim 4, wherein the name of the organ function is displayed on the surface layer in a colour contrasting with the outline colour.
Claim 7
Dependent Claim
52 words
Stop-control apparatus according to any of claims 1 to 5, wherein each of the outlines has an outer perimeter defined by a first elongate rectangle disposed on the panel with its length dimension orientedverti- cally and an inner perimeter defined by a second, proportionally smaller rectangle disposed centrally of the first rectangle.
