Abstract: A foam glass aggregate slicing and reduction machine and system which rapidly, effectively, and economically reduces large pieces of aggregate to required sizes with minimal powdery waste. The machine comprises a foam glass aggregate collection chute having a bottom outlet section for discharging foam glass aggregate onto a holdbar located adjacent to the outlet section. A rotating roller supports a plurality of rotating roller knives which slices large pieces of foam glass aggregate to reduce the aggregate to fragments, with minimal powdery waste. A foam glass aggregate guide member directs foam glass aggregate towards the rotating roller. A foam glass aggregate filtering bar having rows of intervening spaces is located below the guide member and adjacent to the rotating roller.

Abstract: A ladder mounting and retaining system for use on building parapets utilizes a parapet support member secured to the parapet of a building, a ladder support member for retaining the sides of the lengths of a ladder, and a connecting member in the form of a threaded rod, interconnecting the parapet support member and the ladder support member for maintaining these members at a given distance from each other. The parapet support member is secured in position by locking nuts threaded around the connecting member and the ladder support member is secured over the outboard edge of the parapet by retention members. Ladder supports are adjustable on the ladder support member to accommodate ladders of different widths.

Abstract: A query is executed on a multi-database system. The multi-database system includes a first system database and a second system database. The query is partially executed on a first system database by generating a spool. It is determined that it is more efficient to store the spool on the second system database than to store the spool on the first system database, and in response the spool is stored on the second system database. The query execution is continued by accessing the spool on the second system database, completing execution of the query to produce a result, and storing the result.

Abstract: A pick-up truck bed toolbox system utilizes a tool storage box which, in its stored, stationary position, rests on the floor of the bed of a pick-up truck such that it is parallel to the side wall of the truck. Electric motors, which can be remotely operated, are utilized to rotate dual, upstanding screw shafts which are connected via laterally extending cantilever arm members to the front and rear ends of the toolbox. The screw shafts raise the toolbox from its resting position on the floor of the bed of the pick-up truck, to an elevated position over the floor, and the shafts then operate to move the arm members laterally to extend the tool box to a position passed the side wall. The screw shafts can then be activated to lower the tool box to a lowered position outside the truck, adjacent to and alongside the sidewall, thus providing easy and ready access to the toolbox. The same system is utilized to return the toolbox from this lowered position outside the truck, to the floor of the truck bed.

Abstract: A first normally open solenoid valve “A” is connected to passageway (32). A second normally open solenoid valve “B” is connected to a passageway (36). A latching valve (24) includes a valve spool chamber (26) and a valve spool (50) within the chamber. An air-delivery conduit (20) delivers pressurized air to both a first passageway (32) and a second passageway (36). Passageway (32) is connected to one end of the valve spool chamber (26). Passageway (36) is connected to the opposite end of the valve spool chamber (26). The valve spool (50) has two positions. In the first position, passageway (32) is connected with a passageway (40) that extends to an air-operated device (44). Flow through the valve (24) to and from passageway (36) is blocked. In the second position, flow from passageway (32) to passageway (40) is blocked. Also, flow through the valve (24) to and from passageway (36) is blocked.

Abstract: A planning or event organizer comprises dual, rigid covers, onto which organizer components are detachably supported. Items such as a notebook and an expandible folder can be detachably contained within the covers of the organizer. A flexible binder, secured to one of the covers, is insertable into an opening in the other cover, to interconnect the covers and form the organizer. The binder is slidably adjustable within the opening in the cover to permit expansion of the organizer as additional material is received by and stored within the organizer. A strap is available to secure the organizer in a closed position or to assist in maintaining the organizer in a standing display position.

Abstract: A contactless control switch (20) for a vehicle for actuating a system between an open and a first closed circuit position is disclosed. The switch includes a housing (22) and a pivot assembly (24) disposed within the housing. The switch also includes a switch actuator (26) having first and second ends. The switch actuator is coupled to the pivot assembly for producing pivoting motion of the switch actuator in response to a force (84) applied to the switch actuator. The switch also includes first and second proximity sensors (80a and 80b) and a first magnet (70). The proximity sensors are disposed within the housing and the first magnet is fastened to the switch actuator second end. The first magnet is adapted to be selectively displaced into and out of close proximity with one of the proximity sensors when the force is applied to the switch actuator.

Abstract: A pneumatic valve (10) for use in a pneumatic seat (12) of a vehicle is disclosed. The pneumatic valve includes an upper housing (32) and a lower housing (38). The lower housing is slidably received within the upper housing. The lower housing has an upper surface (78) and a lower surface (79). The lower surface has an inlet stem (88), a seat air inlet/outlet stem (90), and at least a first exhaust port (94). The pneumatic valve also includes an elongate poppet (108) slidably mounted within the seat air inlet/outlet port on a first spring (106) to control air flow through the seat air inlet/outlet port. The poppet has an enlarged head portion (110) located at one end and a cam projection (113) located at the other end. A slide member (34) is supported on the upper surface of the lower housing for reciprocating movement relative to the housing to selectively control air flow therethrough. The slide member has an upper surface and a lower surface.

Abstract: A rollover vent valve for use in a pneumatic seat mounted in a vehicle. The rollover vent valve allows air to vent from the air bag(s) in the pneumatic seat in the event the vehicle in which the seat is mounted is severely tilted or overturned. The rollover vent valve includes a housing enclosing a pressure chamber and a valve member. The interior of the pressure chamber is in fluid connection with the air bag(s). The rollover vent valve also includes a vent port that connects the interior of the chamber to the ambient environment. The valve member is located within the pressure chamber above the vent port and forms a seal with the vent port when the pneumatic seat in which the valve is mounted is in an upright position. The valve member includes a weight cage in which a spherical weight is movably mounted. One end of the weight cage includes a valve seal that forms a seal on the valve seat of the vent port.

Abstract: The present invention provides an air valve (10) for inflating and deflating an inflatable. The air valve (10) includes a housing floor (16) with air ports (36, 38), and a slide bar (12) with an air passageway (54) formed therein. The slide bar (12) is supported on the floor (16) by seal rings (92) surrounding the ports (36, 38) and is biased into a center position by a spring (94) positioned in a spring well (28) in the slide bar (12) or the floor (16). Pins (50, 52) project into the spring well (28) and engage opposite ends of the spring (94). A stem extends from a tilt button (66) into a socket (48) on the slide bar (12). When the button (66) is tilted, it moves the slide bar (12), compressing the spring (94) and aligning the ports (36, 38) and the passageway (54) to allow air to pass through the valve (10). The slide bar (12) is prevented from tilting by a stabilizer frame (82) or housing shoulders (220).
