Abstract: A circuit breaker including a housing having a window, a line terminal and a load terminal, and a circuit trip assembly. The circuit trip assembly includes a rotatable cradle, a moveable armature latch and a pivotable trip support including a trip indicator. Upon the occurrence of a tripping condition in the circuit breaker, the trip indicator moves from a first position where it is not visible through the window to a second position where it is visible through the window.

Abstract: A wristwatch dial illumination system with a light guide beneath a light transmissive dial receiving light from an LED mounted on a PC board below the light guide. A pattern of white reflective dots on the bottom surface,of the light guide selectively ejects internally reflected light toward the dial and an absorption pattern of light absorbing material selectively absorbs ejected light, including the bright spot from the LED.

Abstract: A lock-down device for use in a circuit breaker assembly. The device comprises a base for releasably securing the device to the assembly's saddle, an arm portion connected to the base, and a hand portion, connected to the arm portion, for engaging the housing of a first circuit breaker such that when the first circuit breaker and a second circuit breaker is mounted on the saddle the hand portion is intermediate the first and second circuit breakers and the first circuit breaker cannot be inadvertently removed from the saddle. In an alternative embodiment, the hand portion of the device comprises flanges for engaging and permitting the lock-down of the second circuit breaker as well.

Abstract: A carrier for a wrist instrument when it is removed from the wrist band comprises a case made in two pieces of identical construction which slide together and house the wrist instrument and its attachments. The two carrier sections each have a tongue extending across a parting line which is received in a mating channel on the other carrier section. Additional guide pins and recesses hold the assembly in alignment. A holster for the assembled carrier sections cradles the assembly securely and includes a belt clip for attaching the holster to a belt.

Abstract: Recurring digital control signals are provided in a predeterminable time frame, with a high time-dependent resolution and flexibility. Data for the control signals are stored in a write/read memory addressed by an address counter. A comparator is clocked with a multiple of the digital signals bit clock, for comparison with the content of a time Table stored in the write/read memory. For convenience in synchronizing to the time frames of adjacent cells in a cellular network, an offset adder may add the complement of a measured offset (delay) to the comparator clock signal, so that it is not necessary to adjust the values stored in the time Table.
