Abstract
Abstract An apparatus comprising a housing having a cylindrical guide opening therefrom and a driven winding drum journaled therein. A pretensioned elastic tape, for example, stainless steel, is wrapped on the drum and extends through the cylindrical guide such that it forms a rigid air conducting tube. The air cooled device is fixed to the free end of the tube and cooled by air drawn through the tube.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
An apparatus for remotely positioning an air-cooled device such as studio flood lights, comprising a housing having a cylindrical guide opening therefrom, at least one winding drum journaled in said housing, a flexible pretensioned elastic tape wrapped on said drum and passing through said cylindrical guide such that the tape is transformed into a rigid air-conducting tube outside of said housing, said air-cooled device secured to the free end of the tube, means for driving said drum to wrap or unwrap said tape thereon for positioning the air-cooled device toward or away from said housing and a fan associated with said housing for passing air through the housing, tube and air cooled device.
Claim 2
Independent Claim
113 words
An apparatus for remotely positioning an air-cooled device such as studio flood lights, comprising a housing having a cylindrical guide opening therefrom, at least one winding drum journaled in said housing, a flexible pretensioned elastic tape wrapped on said drum and passing through said cylindrical guide such that the tape is transformed into a rigid air-conducting tube outside of said housing, said air-cooled device secured to the free end of the tube, means for driving said drum to wrap or unwrap said tape thereon for positioning the air-cooled device toward or away from said housing and a fan associated with said housing for passing air through the housing, tube and air cooled device.
Claim 3
Dependent Claim
37 words
An apparatus according to claim 1 wherein a plurality of winding tapes with associated winding drums pass through the cylindrical guide and overlap one another in offset manner to form a common tubular shape outside the housing.
Claim 4
Independent Claim
167 words
An apparatus for remotely positioning an air-cooled device such as studio flood lights, comprising a housing rotatably mounted on a base to turn on a vertical axis and having a cylindrical guide opening therefrom, means for turning said housing about said vertical axis, at least one winding drum journaled in said housing and associated therewith a pressure drum biased against said at least one winding drum, a flexible pretensioned elastic tape wrapped on said at least one winding drum and passing through said cylindrical guide such that the tape is transformed into a rigid air-conducting tube outside of said housing, said air-cooled device secured to the free end of the tube to swing about a horizontal axis, means for turning said device about the horizontal axis, means for driving said winding drum to wrap or unwrap said tape thereon for positioning the air-cooled device toward or away from said housing and a fan associated with said housing for passing air through the housing, tube and air-cooled device.
Claim 5
Independent Claim
167 words
An apparatus for remotely positioning an air-cooled device such as studio flood lights, comprising a housing rotatably mounted on a base to turn on a vertical axis and having a cylindrical guide opening therefrom, means for turning said housing about said vertical axis, at least one winding drum journaled in said housing and associated therewith a pressure drum biased against said at least one winding drum, a flexible pretensioned elastic tape wrapped on said at least one winding drum and passing through said cylindrical guide such that the tape is transformed into a rigid air-conducting tube outside of said housing, said air-cooled device secured to the free end of the tube to swing about a horizontal axis, means for turning said device about the horizontal axis, means for driving said winding drum to wrap or unwrap said tape thereon for positioning the air-cooled device toward or away from said housing and a fan associated with said housing for passing air through the housing, tube and air-cooled device.
Claim 6
Dependent Claim
46 words
An apparatus according to claim 3 wherein electrical lines for the means for turning the device about the horizontal axis and/or for the device are secured to or incorporated into the winding tape and are wound or unwound together with the tube by the winding drum.
Claim 7
Dependent Claim
43 words
An apparatus according to claim 3 in which means for driving the winding drum is a continuous electro-motor connected to a counting device, the counting impulses of the counting device being proportional to the length of tape being run out of the housing.
Claim 8
Dependent Claim
41 words
An apparatus according to claim 3 in which the means for driving the winding drum is designed as a stepping motor, the number of the prescribed stepping impulses being proportional to the length of tube being run out of the housing.
Claim 9
Independent Claim
171 words
An apparatus for remotely positioning an air-cooled device such as studio flood lights, comprising a housing rotatably mounted on a base to turn on a vertical axis and having a cylindrical guide opening therefrom, means for turning said housing about said vertical axis, at least two winding drums journaled in said housing, a flexible pretensioned elastic tape wrapped on each said drum and passing through said cylindrical guide such that the tape is transformed into a rigid air-conducting tube outside of said housing, said air-cooled device secured to the free end of one said tape, to swing about a horizontal axis and secured by means of a lever to said other tape, means for driving said drums together to wrap or unwrap said tape thereon for positioning the air-cooled device toward or away from said housing, means for driving said drums relative to each other to swing the air-cooled device about its horizontal axis, and a fan associated with said housing for passing air through the housing, tube and air-cooled device.
Claim 10
Independent Claim
171 words
An apparatus for remotely positioning an air-cooled device such as studio flood lights, comprising a housing rotatably mounted on a base to turn on a vertical axis and having a cylindrical guide opening therefrom, means for turning said housing about said vertical axis, at least two winding drums journaled in said housing, a flexible pretensioned elastic tape wrapped on each said drum and passing through said cylindrical guide such that the tape is transformed into a rigid air-conducting tube outside of said housing, said air-cooled device secured to the free end of one said tape, to swing about a horizontal axis and secured by means of a lever to said other tape, means for driving said drums together to wrap or unwrap said tape thereon for positioning the air-cooled device toward or away from said housing, means for driving said drums relative to each other to swing the air-cooled device about its horizontal axis, and a fan associated with said housing for passing air through the housing, tube and air-cooled device.
