Title: Afterburning of exhaust gases in internal combustion engines
IPC: F01N3/22
Filed: 1975-01-23
Abstract: 1481250 Treating exhaust gas DEUTSCHE VERGASER GmbH & CO KG 23 Jan 1975 [23 Jan 1974] 3018/75 Addition to 1421821 Heading B1W The method of metering extra air to an afterburner as defined in Claim 1 of Specification No is modified in that means are provided for generating a danger signal when there occurs one or more of the following:- a) ignition failure; b) a predetermined excessive concentration of hydrocarbon in the exhaust gases; c) the quality of combustion mixture differs from that required at a given engine speed and load; d) excessive temperature in the exhaust manifold; e) excessive temperature in the afterburner; and wherein said danger signal when generated is applied to a cut-off device which is effective immediately to discontinue the supply of extra air to the afterburner. Air from engine driven pump 17 passes through delivery line 20 to chamber 31 and then at a rate controlled by the position of valve 35 to lower chamber 32 and hence by pipe 39 to exhaust pipe 15 and catalytic reactor 16. The position of valve 35 is controlled as desired in the Parent Specification (Serial No 1421821), valve 35 being mechanically connected to valve 34 which allows air to return to the pump inlet through pipe 22. A safety device 101 is provided which cuts off the supply of air to the reactor if the amount of unburned hydrocarbons reaching the reactor is excessive or the exhaust gas temperature or the reactor temperature is too high. The device consists of two valves on a common spindle, one of which shuts off the air flow to the reactor and the other opens to allow air to return to the pump inlet through pipe 22. The valve spindle is connected to the armature of an electromagnet and is raised when the existence of an unsafe condition causes an electrical signal to be applied to contacts 102, 103. In a first modification, Fig. 2 (not shown) the valve spindle is connected to a diaphragm which is acted on by intake passage vacuum when an electromagnetically operated valve in the vacuum line receives an electrical signal. In a second modification, Fig. 3, the valve unit 101 is not provided and the pipe 37 is connected to a two-way valve 110, which connects the pipe 109 to either the pipe 37 or to the pipe 36. Under normal running conditions, the pressure in chamber 27 is the exhaust pipe pressure, but if an unsafe condition arises, solenoid 114 is energised and connects pipe 109 to pipe 36 so that intake passage vacuum acts on diaphragm 25 and raises valves 34 and 35.

Title: High speed centrifuge and speed control circuit therefor
IPC: H02P25/14
Filed: 1964-01-28
Abstract: 1,018,200. Automatic speed control. BECKMAN INSTRUMENTS Inc. Jan. 28, 1964 [Jan.30, 1963], No. 3523/64. Heading G3R. [Also in Division H2] The speed at which centrifuge rotor 17 is to be driven by series motor 11 is set by multi-position switch 29. As shown, the full output of tachometer generator 19 is placed in opposition to the potential across resistors 59, 60, the error voltage being applied along line 77. When the tachometer is at rest, the error voltage is such that transistors 111, 121, are conductive and transistors 113, 123, are non-conductive, so that, when the charge upon capacitor 137 reaches a peak voltage, uni-junction transistor 139 conducts. Conduction of transistor 139 continues until the potential on line 87 reaches zero, the average energization of transformer 143 being dependent upon the rate of conduction of the transistor 111. The cathode and gate of each of silicon controlled rectifiers 163, 165, in the motor circuit are connected to secondary windings of the transformer 143, whereby they are controlled in accordance with the output of transistor 139. Switch 155 is closed initially, the voltage on line 157 being gradually increased by manual operation of autotransformer 153. As the motor speed increases, the potential across resistors 59, 60 is offset by the tachometer voltage and less power is applied to the motor. If the motor overspeeds, a negative potential on line 77 causes transistors 111, 121, to become non- conductive, and transistors 113, 123, are rendered conductive. Relays 147, 151, are operated to introduce reverse-current braking, the field winding 15 being reversed and full power being applied to the motor from the autotransformer 153. Reversecurrent braking is also afforded when timing switch 79 opens, a centrifugal governor 161 opening switch 159 to prevent actual reversal of the motor. The collector of transistor 113 is connected to the base of transistor 121 through resistor 135 to provide stabilizing feed-back.

Abstract: 806,948. Change-pole motors. BRITISH THOMSON-HOUSTON CO. Ltd. Jan. 15, 1957 [Feb. 10, 1956], No. 4255/56. Class 35. [Also in Groups XXXVII and XXVI] A change-pole induction motor for starting gas turbines is provided with automatic control means to halve the number of effective polepairs of the motor in response to a predetermined change in turbine temperature, or motor current or voltage, which indicates igniting of the fuel. As shown, the motor is of the threephase 4/8 pole type, and the 8-pole stator connection is shown with full lines 1, 2, 3, and the 4-pole connection with interrupted lines 4, 5, 6. The 4-pole and 8-pole equivalent rotor circuits are shown in Figs. 2 and 3 respectively. In another arrangement, the motor is of the kind described in Specification 806,947 where the rotor has a low-resistance high-inductance winding for running, and a low-resistance lowinductance winding for starting, the latter winding being connected through slip-rings to external resistance. The pole-change may be effected by means of a current or voltagesensitive relay in the stator or rotor circuit, and the setting of this relay may be varied to compensate for changes in power demand for turbine starting due to changes of the ambient temperature. In another embodiment the polechange is initiated in dependence upon a temperature-sensitive element arranged in a part of the engine where a temperature rise occurs when the turbine starts. The rotor resistance may be changed automatically and at the same time as the pole member. The desired effect of high rotor resistance during 8-pole operation and lower rotor resistance during 4-pole operation is provided by connecting external resistors r, R to terminals a . . . e corresponding to those of Figs. 2 and 3, the value of resistors R being high compared with that of resistances r.
