Abstract: 1,270,217. Crankcase ventilating; treating charge. DAIMLER-BENZ A.G. April 23, 1970 [April 25, 1969], No.19601/70. Heading F1B. I.C. engine crankcase ventilating apparatus comprises an extraction duct 14, Fig.2 normally communicating with the crankcase and means for cutting off a connection with the atmosphere when a valve 19 in the exhaust passage 12 is closed. When the latter is closed, e.g. during engine overrun, a linkage 18 also closes a valve 17 to cut off the connection to atmosphere. Gases forced out of the crankcase due to pressure build-up in passage 12 accumulate in reservoir 16. An additional normally-closed valve 22 is opened to admit atmospheric air if the crankcase suction is excessive. In another embodiment crankcase gases are passed to induction passage 113, Fig.3 by a pump 123. When valve 119 is closed, duct 114 is cut off from atmosphere and connected to reservoir 116. An excess pressure in reservoir 116 opens valve 124 to open a connection to the induction passage 113.
Patent GB-596709-A (GB)
Title: Improvements in and relating to automatic control systems
IPC: G05B11/01
Filed: 1945-07-31
Abstract: 596,709. Automatic control systems for furnaces. REID, R. July 31, 1945, No. 19647. [Class 38 (iv)] In an automatic temperature pressure or other control system, deviations of the variable from the desired datum converted by an appropriate sensitive element, e.g. a thermocouple into a corresponding D.C. potential and together with or potential corresponding to the datum value selectively applied after amplification to the grids of thyratrons to energize relays which control the supply to a motor correctively operating the furnace full supply valve. The thermocouple a is heated in the furnace and is connected between earth and the control grid of the pentode V2 coupled to valve V1 in push-pull. Potentiometer R1 is connected between earth and the control grid of pentode V 1 and the voltage tapped off is adjusted until millivoltmeter b indicates that it is equal to that of the thermocouple a at the derived furnace temperature. The anodes of V1, V2, are connected to the control grids of valves V3, V4, the anodes of which are similarly connected, through resistors R11, R12 to the grids of thyratrons V5, V6, respectively in series with the operating coils of relay operated mercury switches M1, M2. The latter have each three contacts which are connected respectively to lamps G and R, contacts c and d and to the supply mains. The contacts c and d are associated with separate fields of reversible motor e actuating the fuel valve of the furnace. With the temperature of the furnace at the desired value the voltages at the grids of V1 and V2 and therefore the anode currents are equal. Consequently the anode currents of V3 and V4 are equal, the thyratrons V5 and V6 remain extinguished and lamps G, R, are lit. With a fall of furnace temperature the thermocouple voltage and hence the voltage applied to the grid of V2 is reduced. The consequent change in anode currents of V3 and V4 produces bias voltages which cause thyratron V5 to fire. Relay M1 is actuated, lamp G extinguished and the circuit to contact C is completed causing the motor e to run in a direction to open the fuel valve. Similarly, a rise of furnace temperature causes the thyratron V6 to fire, the relay M2 to operate, the lamp R to be extinguished and the contact d to be connected to the supply. The motor e then runs in the reverse direction, to close the fuel valve. Limit switches f, operate at the fully open and closed positions and the speed of motor e is regulated by resistor R13. The double throw switch S3, S4, S5, S6 in its upper position permits the automatic operation of the device. In the lower position S3 connects the meter b across the thermocouple and reads the furnace temperature directly and the pushbuttons P1, P2 are connected to permit of manual operation of the control. In the open position the apparatus is inoperative. Pressure control may be effected by the substitution of a pressure-sensitive device, e.g. a quartz plate, in place of the thermocouple and of an air pump for the fuel valve.

Abstract: 147,738. Coppee et Cie, E. Jan. 20, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Coke ovens.-In a Coppee-type coke-oven which may be worked regeneratively or not, and in which the directions of flow of air and gas for combustion are not reversed, two central passages A and B, for the supply of air and for the removal of combustion products respectively, are placed alternately in communication with parallel passages C and D, each connected with a series of regenerator chambers on the corresponding side of the oven. The Figures show the oven arranged for regenerative working, air entering at H and being directed by the reversing valve V to a flue I, from which it passes up through the regenerators to the passage C. From thence it enters a cross flue E past a raised valve R<1>, and is led to the passage A, from which it is distributed to flues M, Fig. 2, and thence, by way of channels L, to the combustion flues K. Gas is supplied through passages N, and the combustion products pass down the flues P to the passage B, and thence to the passage D by way of the cross flue F and the open valve R<4>. They then pass through the regenerators to the flue J by which they ara led to the chimney. On reversal, the valves R<1> and R<4> are closed, R<2> and R<3> are opened and the valve V is reversed. For non-regenerative working, the valves R<1>, R<2> are closed, R<3> and R<4> are opened, and partitions P separating the passage B from the passages C and D are raised. Air is then drawn direct into the passage A through a channel (not shown), whilst the combustion products are led by a flue U to a boiler battery. Another form of oven is described in which the passages C and D are dispensed with, and the combustion products and air pass through the whole length of the regenerators from one end of the battery to the other.
