Abstract: A geographical chronological device which simultaneously indicates the time in multiple cities or countries, and displays fluctuations in day or night in a geographic location. The earth clock has a semi-transparent world map depicting a polar planetary projection of the world from the north or south pole. An adjustable shadow disk is disposed adjacent to and partly visible through the semi-transparent world map. The shadow disk has a periphery with time indicia disposed about the periphery. The adjustable shadow disk has an adjustable dark portion to indicate night and an adjustable light portion to indicate day. The dark and light portions adjust to indicate relatively greater or lesser night and day according to the change in seasons. A clock movement provides relative movement between the semi-transparent world map and the adjustable shadow disk.

Abstract: A secure stowage system having first and second support members. The second support member is releasably attached to a support system such that the second support member can only be removed from the support system by first moving the second support member according to a predetermined adjustment. The first and second support members have receiving means. A lockable item is configured to fit between the first and second support members. The lockable item has a lock and first and second mating means. The first mating means are adapted to engage the receiving means of one of the first and second support members. The second mating means are likewise adapted to engage the receiving means of the other of the first and second support members. The first mating means are selectively retractable toward the lockable item, but only when the lock is in an unlocked position. The first mating means are unretractable when the lock is in a locked position.
