Title: Gas Fired Water Heater
IPC: F23J13/04
Filed: 1979-04-25
Abstract: A balanced flue water heater to be mounted on a wall, comprises a front chamber 10 housing the gas burner etc., and a rear mounting compartment MC into which is led a fresh-air pipe 39 and from which is led an exhaust pipe 44. To enable these pipes 39, 44 to pass out of the mounting compartments rearwardly or laterally of the heater, the mounting compartment houses a junction box 32 mountable by a flange plate 33 on the rear wall 17 in various angular positions and provided with a rear opening 37 and side opening 38, and the flange plate has an aperture support for the pipe 44. The exhaust pipe is fastened to the flange plate at the aperture thereof and is led out of the junction box via an opening 37 or 38 to which the fresh-air pipe is connected concentrically of the exhaust pipe. By the use of the flange plate and the alternative openings 37, 38, the junction box permits the pipe connection to be made from above, below, either side or from the rear of the mounting compartment. <IMAGE>

Patent GB-2098709-A (GB)
Title: Air flow control device
IPC: F23L3/00
Filed: 1981-05-16
Abstract: An air flow control device arranged to deliver air to a combustion appliance has a first mode wherein air delivery is restricted to a level sufficient to maintain minimum combustion, notwithstanding variations in air demand or supply; and a second mode wherein such restriction is removed. An appliance air delivery opening 1 is substantially obstructed by a hinged flap 3. A gap 5, defined between the flap and a lower plate member 6, permits air delivery to the appliance sufficient to maintain minimum combustion therein. Increased combustion or draughts through the appliance cause the flap to swing towards a position 7. The member 6 has a curvature arranged to reduce the gap 5 in dependence on the pressure causing the flap to swing, such that volume air flow through the gap is substantially constant. The restriction to minimum combustion can be removed by activation of solenoid 9 to raise stop 8, which activation can be linked to sensors, operator controls or a booster fan.

Title: Radiopaging arrangements
Inventor: LAX ALEXANDER PETER
IPC: H04L1/00
Filed: 1981-11-30
Abstract: A radiopaging arrangement comprises a plurality of adjacent radiopaging systems each comprising a transmitter and a plurality of receivers. The transmitters are operated at the same frequency and each transmitter is arranged to commence each transmission with a digitally coded preamble recognisable by the receivers of the associated system. The receivers are responsive to recognition of the preamble signal to switch from an idle mode to an operational mode. To ensure that a transmission in any one system will not cause switching of the receivers of the other system or systems into the operational mode, the coding of the preamble is different for each said system. Typical different preambles for different systems are shown at (a) to (d) in Figure 3. <IMAGE>
