Abstract: A bridge containment system (10) comprises at least two vertically positioned cables (12) which comprise at least a first cable (12A) and a second cable (12B). The bridge containment system (10) farther comprises least two chains (16) interwoven and slidably mounted onto the plurality of vertically positioned cables (12), a first chain (16A) is interwoven and slidably mounted onto the first cable (12A) and a second chain (16B) is interwoven and slidably mounted onto the second cable (12B). The bridge containment system (10) further comprises at least one fence (18) is securely attached along a first distal edge to the first chain (16A) and securely attached along an opposite distal edge to the second chain (16B), when the first cable (12A) and the second cable (12B) are raised and lowered, the at least one fence (18) is concurrently raised and lowered functioning to contain falling debris.

Abstract: A window support system for a bay or bow window to be installed on a home or other building wherein the system is secured to the head board and seat board of the unit and wherein the system comprises a vertically extending hollow pipe or solid rod disposed between inner and outer panes of glass which is secured in place by means of standard fastening devices both to the head board and seat board and wherein a turnbuckle is disposed between two threaded rods and at an angle of preferably 221/2 or 45 degrees from the head board. A standard pipe elbow is employed between the vertically extending rod or tool and the threaded rod to maintain the angle to the head board. An eye bolt is affixed to the existing house header and a second threaded rod having a hook on one end, distant from the turnbuckle, for cooperation with the eye bolt. Upon installation of the window the turnbuckle can therefore be rotated in either direction to properly level and secure the window to the house.

Abstract: A pulsed brake drive for an electro-magnetic brake incorporating a permanent magnet which can be pulsed into either an on or off stable state wherein the brake is driven by a very short pulse depending on brake voltage. In the event of a failure of any one phase of the line the drive shuts off the motor and applies the brake. Further, if the power supply to the motor is off, the brake, which is normally on, can be released and then re-applied by a pushbutton. Power to drive the brake is battery supplied which in turn is kept fully charged at all times from main AC power. It is this unique circuitry and combination which introduces an energy efficient motor brake driven by a short pulse-not dependent on continuous voltage.
