Abstract: 568,658. Fire-extinguishing. PYRENE CO., Ltd., and BEDFORD, H. E. June 7, 1941, No. 7218. [Class 47 (ii)] In a method of producing foam for fireextinguishing in which water and a foamforming compound are intimately mixed with air entrained by a jet or series of jets, a solution capable of yielding foam having at least six times the volume of the solution is used, and the volume of air is restricted by making the ratio of the smallest total area through which all the air must pass to the total jet area lie between 5 : 1 and 12 : 1. Preferably, the solution is one giving eight times its volume of foam, and the ratio above referred to lies between 8: 1 and 10: 1. Fig. 1 shows an apparatus for the protection of an oil tank 1, foam being introduced in the bottom of the tank through a horizontal pipe 3 connected to a vertical pipe 2, a frangible seal 15 being placed across the connection. Foamforming solution from a pipe 7 enters the pipe 2 through a nozzle head having five bores each ¢ inch in diameter, the jets intersecting at the entrance of a throat 9, and air is entrained through a conical shield 10 which is 3¢ inches in diameter, giving a ratio of about 10 : 1. The.mixture of air and solution travels through an expanding cone 11 into the pipe 2, which is fitted with a triangular shaped baffle 12. Modifications are described in which two jets are arranged in series, or in which a number of jets are arranged in parallel. Specifications 272,993, [Class 47 (ii)], and 403,291 are referred to.

Title: Improvements in or relating to relay control circuits

IPC: H03K3/2893
Filed: 1963-03-01
Abstract: 1,012,127. Transistor circuits. S. SMITH & SONS (ENGLAND) Ltd. April 3, 1964 [March 1, 1963], No. 8231/63, Heading H3T. In a circuit responsive to a predetermined change in an input voltage relative to a reference voltage, the input and reference voltages are compared in a differential amplifier the output of which is used to change the state of a trigger circuit following a change in input voltage by at least a predetermined amount, the trigger circuit then altering the reference voltage so as to make the circuit less sensitive to changes in input voltage. As shown, the input voltage is fed via a variable attenuator 1 and an emitter follower (Fig. 2, not shown) to the base of a differential amplifier 2 comprising an emitter-coupled pair of transistors. A reference voltage is derived at 14 from a bi-stable circuit 5 and is fed to the base of the other transistor of amplifier 2. Normally, the output of amplifier 2 is passed via a switch 32, short circuiting rectifier 29, to a Schmitt trigger circuit which maintains a relay 4 energized. If the attenuated input voltage 15 rises above the reference voltage at 16, the Schmitt circuit 3 changes state, releasing relay 4 and reversing' the state of the bi-stable circuit 5 which reduces the reference voltage 16 so that the relay 4 will not be energized again until the voltage at 15 falls below the new reference level at 16. The extent of the change in reference voltage is adjustable by resistors 7, 8. The supply on lines 12, 13 may be stabilized by a Zener diode and is further stabilized by a transistor circuit 11 before being fed to the amplifier 2 in the bi-stable circuit 5. Switch 32 may be set to the right hand position so that alternating current signals can be rectified at 29 and smoothed at 30. In the preferred embodiment (Fig. 2, not shown) the amplifier 2 comprises PNP transistors and is coupled to the Schmitt circuit 3 via an NPN transistor. The bi-stable circuit 5 may be replaced by auxiliary contacts on relay 4.
