Abstract: An operator for a barrier, such as an upward acting door, includes a control unit having two optical limit switches providing output signals to a controller to effect shut-off of the operator motor when the door reaches open and closed limit positions. The limit switches preferably include LED emitter and phototransistor sensor elements and are preferably mounted on a circuit board in close proximity to a screw member which rotates in timed relation to the position of the door. Linearly movable nut members are mounted on the screw member and include or engage optical shield members which move into positions to provide respective output signals from the optical switches. The door closed optical limit switch may incorporate a pre-limit switch function to override a signal from a door bottom edge obstruction sensor.

Abstract: A new and improved thermal type bulkhead assembly comprises a pair of new and improved thermal type bulkhead members which are adapted to be adjustably positioned with respect to each other in an overlapped mode in the widthwise direction whereby oppositely disposed side edge portions of the pair of bulkhead members can effectively engage the oppositely disposed interior side walls of the refrigerated cargo container, while upper sections of the bulkhead members can flexibly engage the ceiling portion of the refrigerated cargo container. In this manner, the lateral extent or width dimension x of the thermal type bulkhead assembly, as well as the vertical extent or height dimension y of the thermal type bulkhead assembly, can be adjustably varied whereby the thermal type bulkhead assembly of the present invention is effectively universal in structure so as to be capable of being utilized within different refrigerated cargo containers characterized by means of different internal width and height dimensions.

Abstract: A bulk material cargo container liner system comprises an inflatable bulk material cargo container liner which has at least one vacuum discharge tube member disposed internally within the bulk material cargo container liner and extending throughout the longitudinal extent thereof for discharging bulk cargo material outwardly from the bulk material cargo container liner, and at least one inflatable air bag component which also extends throughout the longitudinal extent of the bulk material cargo container liner and is initially disposed in a deflated state but which is adapted to be disposed in an inflated state when the bulk cargo material can no longer be evacuated under natural gravitational forces.

Abstract: An apparatus (10) for feeding sliders (31) from a source of sliders to the slider insertion area (27) of at least two slider insertion devices (18, 19). A sensor (30, 52) on a sender track (20, 21) detects a lack of sliders (31) in the sender track. A signal is sent from the sensor (30, 52) to actuate a vibratory bowl (14) of sliders (31) and a plunger (35) to open a passage, thereby releasing the sliders (31) to a sender track (20, 21). When a sensor (46, 56) detects a lack of sliders (31) in a loading rack (25, 26) or a slider insertion area (27), the sensor (46, 56) signals a plunger (44, 58) and a pneumatic valve (48, 60) to open a passage to provide an air blast, thereby launching the sliders (31) onto the slider insertion area (27) of each slider insertion device (18, 19).

The catheter tip proximal end and/or the stabilizer distal end comprises a docking section adapted to releasably engage a portion of the implant. Each docking section has an engagement geometry comprising a flared engagement surface that extends inside a short axial length of the implant or a pocket having a bottleneck geometry.

Abstract: An apparatus (10) for and a method of transporting sliders to the slider insertion area (27) of a slider insertion device (18). A first sensor (30) on a sender track (20) detects a lack of sliders (21) in the sender track. A signal is sent from the first sensor (30) to a controller (24) to actuate a vibratory bowl (14) of sliders (21), and a first solenoid operated plunger (34) thereby releasing the sliders (21) to the sender track (20). Air connections (38) pneumatically push the sliders (21) along the sender track (20) to a second solenoid-operated plunger (44). When a second sensor (46) detects a lack of sliders in the loading rack (26), the second sensor (46) signals the controller (24) to actuate a second solenoid-operated plunger (44) and a solenoid-operated pneumatic valve (48). The second solenoid-operated plunger (44) opens a passage and the pneumatic valve (48) opens to provide an air blast, thereby launching the sliders (21) into the feed tube (22) and onto the slider insertion area (27).
