  • Patent number: 6786005
    Abstract: Emergency release burglar bars having electronic locks that are actuated remotely by a signal generated by a smoke detector alarm provide security and will automatically unlock upon detection of smoke in the premises without human intervention to allow safe exit from the premises, and easy access and entry to the premises by emergency personnel. When the smoke detector/alarm senses smoke in the premises, its alarm is “powered on” to sound the alarm. A relay connected with the alarm circuit is activated simultaneously with the sounding of the alarm, which activates an “unlock” switch of a transmitter connected with the relay to transmit an RF “unlock” signal. Receivers on each of the electronic locks receive the transmitted signal, and activate an actuator, which actuates a mechanism to retract the bolt of the lock, allowing the burglar bars to be swung open.

  • Patent number: 6602476
    Abstract: Apparatus and process for heat exchange with fluid beds comprises heat-exchange tubes located longitudinally with respect to the axis of a fluidization zone with a rectangular pitch, one side of which having a length at least one and a half times the length of the other side and/or with a triangular pitch, having two sides each at least one and a half times the length of the shortest side reduces the impact of the heat-exchange tubes on the fluidization characteristics of the fluid bed. The invention is particularly suitable for oxidation reactions using molecular oxygen-containing gas in the presence of a fluid bed of fluidizable catalyst, such as (a) the acetoxylation of olefins, (b) the oxidation of ethylene to acetic acid and/or the oxidation of ethane to ethylene and/or acetic acid, (c) the ammoxidation of propylene and/or propane to acrylonitrile and (d) the oxidation of C4's to maleic anhydride.
