Abstract: A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. Each fleet vehicle has an assigned time slot to transmit its reporting information over a communications network without interfering with transmissions from other vehicles in their own respective time slots. A timing control phase lock loop (PLL) provides precise time synchronization for timing corrections from a global positioning system (GPS) based time reference. A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption.

Abstract: Containerized medical waste is treated by shredding, and then passing the shredded material, by means of a screw conveyor, through a direct steam impingement stage and a dehydration stage in which the material is brought into contact with a hot surface to vaporize moisture and thereafter passed through a low pressure chamber in which the vapor is drawn off.

Abstract: An object-oriented development system for developing control schemes for facilities includes a device diagramming component for describing a physical description of a facility and a logical definition of a control scheme for the facility. The device diagramming component includes a mode for selecting device symbols representative of equipment or control functions used in facilities. The device symbols are selected from an object-oriented repository containing a plurality of device symbols and device objects. Certain types of device symbols relate to device objects containing logical instructions and configuration information relating to the represented equipment or control functions. The device diagramming component also includes a mode for interrelating in a graphical manner the selected device symbols and their corresponding device objects into a device diagram representing the physical description of the facility and the logical definition of the control scheme for the facility.

Abstract: Containerized medical waste is treated by a process in which the materials are carried by a conveyor under a negative pressure to a multiple-stage shredder. Sodium hypochlorite is added at several points in the shredder section of the apparatus. The output of the shredder is compressed and the liquid component which is separated out is recirculated. The compressed solid is conveyed through a conveyor in which the temperature is maintained at a level just under 212.degree. F. by the introduction of steam. The pressure is maintained at or below atmospheric pressure at all points in the system to prevent release of contaminated materials into the atmosphere. By using the combination of sodium hypochlorite and steam, it is possible to eliminate live microorganisms entirely while still taking advantage of low pressure to avoid accidental release of contaminated materials.

Abstract: There is provided an apparatus which is used to temporarily support one end of a cross piece during construction of a deck or fence rail. The apparatus is in the form of a C-shaped frame having an elongated base plate and a pair of leg plates extending from each end of the base plate. An adjustable clamp member is attached to one of the legs for securing the apparatus to a first vertical beam. A platform is attached to the other leg and receives one end of the cross piece for holding that end of the cross piece in position on one beam while the other end is secured to a second adjacent spaced apart beam. Once a cross piece has been attached to the two adjacent beams, the clamp may be flipped over and the other side of the clamp may be attached to the second beam so that another cross piece may be abutted against the first cross piece and attached between the second beam and a third beam. The apparatus enables cross pieces to be attached to beams by one person.
