摘要： An optical matrix switch station (1) is shown mounting a plurality of optical switch units (15, 17), each of which includes a mirror (29), moveable in two axes, for purpose of switching light beams from one optical fiber to another. A mirror assembly (41) is formed from a single body of silicon and comprises a frame portion (43), gimbals (45), mirror portion (47), and related hinges (55). Magnets (53, 54) and air coils (89) are utilized to position the central mirror surface (29) to a selected orientation. The moveable mirror and associated magnets along with control LED's (71) are hermetically packaged in a header (81) and mounted with the air coils on mounting bracket (85) to form a micromirror assembly package (99) mounted in each optical switch unit.

摘要： An optical switch device includes a first array (20) of reflectors (22), each associated with a separate optical fiber input (12), and a second array (30) of reflectors (32), each associated with a separate fiber output (14). The reflectors (22 and 32) are positionable to direct an optical signal from any one of the fiber inputs (12) to any one of the fiber outputs (14). The optical signal is directed along an optical pathway between the desired fiber output (14) and its associated reflector that is substantially aligned with an axis extending centrally from the fiber output. Preferably, symmetrical fiber beam forming units for forming the optical signal into a focused beam are included between the fiber inputs (12) and the first array as well as between the second array (20) and the fiber outputs (14). A method for switching optical signals between an input and an output optical fiber end involves forming the optical signal emitted from the input fiber end into a focused beam wherein rays from a point on the input fiber end are convergent. The focused beam is directed towards the output fiber end using at least two positionable reflectors oriented to direct the signal so that, prior to reaching the fiber output, it propagates along an optical pathway that is substantially aligned with an axis extending centrally from the output fiber end.

摘要： A three phase hermetic protector for electrical apparatus has a pair of terminals extending through a header with first and second elongated heaters mounted on the terminals and extending away from the header. A rigid support is attached to the header between the terminals and extends away from the header and mounts a third elongated heater extending back toward the header. A snap acting disc is cantilever mounted on the free end of the third heater and mounts thereon a pair of movable contacts adapted to move into and out of the engagement with stationary contacts mounted at the free ends of the first and second heaters. The rigid support mounts a calibration screw beneath the free end of each of the first and second heaters to independently adjust the vertical position of the stationary contacts.

摘要： A protection system for a dynamoelectric machine providing a plurality of protective functions comprises a module having as a first function over temperature protection including thermal sensors adapted to be placed in heat transfer relation with the windings of the machine. The sensors which may be connected in series or in parallel are connected to a sensing circuit provided with shorted sensor protection. When connected in parallel a channel is provided for each sensor and is isolated from one another. Other functions include a minimum off delay timer which prevents rapid cycling of the machine. An oil pressure timer particularly useful with a compressor motor to sense oil pressure between the output of the oil pump and the crankcase in order to deenergize the motor should there be inadequate oil pressure for a selected period of time, a low voltage cut out network in the event of the occurrence of low voltage conditions, and a circuit to facilitate use of controls in the output side of the system if desired while permitting operation of the system only on the condition of output current flow.The minimum off delay timer can be modified to provide a manual reset circuit which will lock out or prevent energization of the machine each time the protection circuit is tripped. Reset can be accomplished only by removing power to the module and reapplying said power.
