Abstract: In spiral scanning apparatus for bubble chamber photographs, comprising an elongated plane mirror which is lengthwise inclined upwardly and outwardly to an axis about which it rotates, to reflect toward the axis light shone downwardly onto it, and a periscope which rotates to have its eye face the mirror and simultaneously moves axially to scan along it, superimposed slotted fixed and movable mask means in front of the periscope eye enable sensitivity and selectivity to be adjusted for different photographs.

Abstract: A scanner for bubble chamber photographs comprises a rotatable mirror-carrying outer member and an inner periscope member that rotates with and moves lengthwise relative to the outer member. The periscope member has accurately straight track surfaces along its length that parallel the rotational axis and lie in substantially perpendicular planes which respectively extend to opposite sides of said axis. Each of said tracks is engaged by rollers carried by the outer member at fixed axially spaced locations. Other rollers on the outer member engage the periscope member under radially inward bias to maintain the track surfaces guidingly engaged with the first mentioned rollers.

Abstract: 1286481 Bearings SAAB-SCANIA AB 25 Aug 1969 [28 Aug 1968] 42246/69 Heading F2A [Also in Divisions G1-G2] A spiral reader has a rotatable mirror 30 arranged to describe a cone and a periscope 22 mounted within the mirror support 21 for rotation therewith and movable relative to the support along the support axis, the periscope mounting comprising pairs of first 44 II and second 44 I guide members. The first guide members are yieldably mounted with respect to the support 21 whereas the second guide members are rigidly mounted. The guide member 44 II , 44 I of a respective pair bear in opposed directions on respective axially extending guide surfaces 43 II , 43 I on the periscope, the line of action of each guide member being offset from the axis. The guide members of a respective pair oppositely face one another, and their respective guide surfaces are parallel. The guide members 44 II , 44 I comprise rollers 45 mounted on shafts lying in a plane perpendicular to the rotation axis. The members 44 II have an upwardly extending tongue 47 II attached to support 21 by bolts 51 and tightened to the periscope by screws 52. This allows for adjustment of the bearing load of the member on its respective guide surface. The members 44 I have adjusting screws 49 which have a conical guide surface 53 engaging along a portion of the cylindrical surface of an aperture 54 to adjust the position of the member toward or away from its respective surface.
