Abstract: 341,559. Heating liquids by direct contact of hot gases. BRUNLER, A. O., 31, Colville Terrace, Notting Hill, London. Oct. 22, 1929, No. 32087. [Class 64 (i).] Water or other liquid in a tank a is heated by direct contact with a flame in an internal chamber d connected with the lower and upper parts of the tank by pipes b, h. The combustion products from the upwardly directed burner e rise in the pipe h and draw in water from the chamber d. The heated liquid is led through a separator m, from which the separated combustion gases escape to the atmosphere through a pipe l. The mixture of fuel and air for the burner pass through a preignition chamber f. Ignition is carried forward from the chamber f to the burner mouth by increasing the supply of the combustible mixture. Specification 300,819, [Class 64 (i), Heating liquids &c.], is referred to.

Patent GB-328594-A (GB)
Abstract: 328,594. Tollemache. H. D. Jan. 26, 1929. Totalizators.-The display of totals, under the control of the various counters, occurs intermittently and simultaneously only so as to facilitate the reading and comparison of the numbers. The shaft B rotates in accordance with the number of bets received through the lines A<1> and carries a contact disc M serving as one member of a hunter gear controlling a shaft M<2> driven by a motor N'. While the conducting portion of the disc M is engaged by an arm M<1> extending from the shaft M<2> a magnet M<3> is energized and the motor circuit consequently closed. The shaft M<2> drives a contact arm 0' controlling the display apparatus R<6> which may be as described in Specification 328,613, but periodically the circuit through the arm is broken by a time switch U driven at constant speed by a motor V<1>. Moreover, while this circuit is complete, the circuit through the magnet M<3> and the hunter switch M is broken thus enabling the display to persist without change until by the continued rotation of the time switch the display circuit is broken and the hunter switch circuit re-established so that the shaft M<2> can resume its correct relation with shaft B. By manipulation of switches W, W<1>, the time switch can be cut out as regards its control of either or both circuits. The diagram shows a lay-out in respect of six denominations with connections for receiving bets of 2/-, ú1, ú10 and ú100 and with transfer switches B<1>, D<1> &c. between the denominations. The hunter-switch and display circuits are connected up in parallel respectively, with wires R<5> and S so that the interruptions of all the circuits through the display apparatus occur simultaneously. According to the Provisional Specification there may be two hunter-switch devices in series for each denomination, the second device serving to drive the display apparatus.
