Abstract: 1296408 Selective signalling INSTRUMENT SYSTEMS CORP 17 Feb 1970 [20 Feb 1969] 9354/72 Heading G4H [Also in Division H4] The description is of part of the entertainment service system of the parent Specification 1,296,405. The claims relate to the supervisory control system in which a number of utilization circuits are controlled by respective control circuits with groups of control circuits connected to respective coders 28A arranged serially in a loop 34 connected to a central column timer 26. The utilization circuits, e.g. call lights, bells, and reading lights &c. are connected in groups to decoders, also arranged serially in a loop 36 connected to the column timer 26. Timing signals from the timer 26 activate the controls and corresponding utilization circuits simultaneously in sequence with all the controls or utilization circuits connected to one coder or decoder being activated before timing signals are fed through that coder or decoder to the following coder or decoder in the sequence. The data signals indicating the conditions of the control circuits are fed to the decoders over a common data line 32. The data line is tapped at a supervisory control position 38, 40, and energizes a lamp and a chime while any of the service call light controls is in a calling position. The coder is described with respect to Fig. 7 (not shown) and the decoder with respect to Fig. 8 (not shown). A testing device which transmits a signal over the audio distribution system and causes setting of the local controls to a condition to transmit a characteristic signal to the utilization circuits is described and is the subject of Specification 1,296,406.

Abstract: 1302895 Liquid fuel supplies for burners ESSO RESEARCH & ENG CO 9 Feb 1970 [7 Feb 1969 23 Oct 1969] 6653/69 and 51902/69 Heading F4T In a fuel supply arrangement to a burner 10 having a reservoir 11, fuel is supplied by an electrically operated bellows 13 from a storage tank 12 to the burner reservoir, the fuel level in the reservoir being controlled by a float operated control valve 31. As shown in Fig. 3, the valve 31 comprises a flexible strip 32 anchored at one end 33 and covering the valve seat or fuel outlet 34, the fuel outlet being positioned above the fuel level in the reservoir. A pivoted bell crank lever has a float 37 attached to one arm 35a, and a valve actuating pin 38 fixed to the other arm 35b. Fuel is pumped through a fuel supply pipe 30 past the strip 32 to the reservoir, the strip 32 returning to its seat 34 after each pumping stroke assisted by a U- shaped member 38a attached to the pin 38. As the fuel reaches the required level, the float 37  moves upwards, causing the pin 38 to move the strip 32 away from its seat, so that on the next suction stroke the pump merely draws in air through the open valve 31, preventing further supply of fuel. An alternative valve (Fig. 4, not shown) is described in which the valve closing member is in the form of a disc (40) which is actuated by a spindle (42) fixed to a float 43. Also described is an arrangement for fuel supply to several burners (Figs. 2 and 5, not shown) in which the float operated fuel level control valve (50) is closed by the action of the float (55), a pressure relief valve (56) being provided in the system. In all cases, a non-return valve (25, Fig. 6, not shown) is used as an outlet from the storage tank. In installations where the maximum fuel level in the storage tank is above the fuel level outlet of the control valve, an anti-siphon device is included in the fuel supply line between the storage tank and the pump.

In other embodiments, the voltage multiplier may be replaced by fixed and variable power supplies, the latter being controlled directly from the differential amplifier, Fig.1, (not shown), and the control signal, derived from the product of the phosphor current and the voltage between the channel plate and the phosphor, may be used to control the power dissipated in the phosphor, Fig. 2.
