Title: Improvements in or relating to servo-motor control mechanism
IPC: F16D48/04
Filed: 1941-08-25
Abstract: 551,532. Servomotor control mechanism. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, W. H. J. Aug. 25, 1941, No. 10835. [Class 80 (ii)] Relates to servomotor control mechanism of the kind wherein a manual force-transmitting connection embodies lost motion, the taking up of which brings into action a servomotor to assist the movement of the device operated. According to the invention the servomotor acts to stress a resilient element the force of which is sufficient to balance a substantial proportion of the resistance of the device operated. As shown, appied to friction clutch control mechanism, a lever 22 is linked to the clutch pressure plate 11 and is normally held by a spring 24 against a stop 23 when the clutch 10 is engaged. A pedal pad 42 is carried by the lever 22 with slight lost motion and is connected-by a Bowden cable 45 to a valve plunger 34 controlling the supply of pressure or vacuum to a servomotor 25. The piston 26 of the servomotor is connected to the clutch 22 through a spring 28 which is unstressed when the clutch 10 is engaged. To declutch, pressure is applied to the pad 42 and the lost motion is taken up. This causes movement of the valve plunger 34 so that the servomotor 25 is energized and the piston 26 makes a stroke thus stressing the spring 28. Further depression of the pedal 42 will then cause movement of the lever 22 to declutch. An electric solenoid device may replace the fluid pressure servomotor.

Class 123 (iii) [Also in Groups XII and XXIX] A steam &c. boiler comprising a furnace 10 lined with steam-generating tubes such as 15 and provided with a gas outlet 12, the latter locating a first superheater 18 and leading to parallel passes 24, 28 locating a second super-heater 20 and an economiser 21 as shown, is fired by three rows of pulverised coal burners, 30A, 30B, 30C mounted in the air chambers 36A, 36B, 36C to which secondary air is supplied by a forced draught fan 32 through ducts 33, 34. The fan 32 also supplies primary air through a chamber 37 and duct, such as 40C, to the fan inlet connection of each of the pulverisers 31C, there being a pulveriser associated with each row of burners and the coal output of said pulveriser being controlled in known manner by regulation of the primary air flow thereto. Each duct 40C is fitted with a damper 42C and is provided with a dampered tempering air inlet connection 41C; dampers are also fitted in ducts leading from the secondary air duct 34 to the chambers 36A, B, C. The superheat temperature is regulated by selective firing of the burners with, if necessary, attemperation of the superheated steam or, preferably, control of the respective gas flows through the passes 24, 28 by means of dampers 26. At full load all three rows of burners, each supplying approximately one-third of the total fuel requirement are in operation at full capacity, but as the load is reduced the fuel supply to the lower rows 30B, 30C is reduced until, at about 55 per cent load, the row 30C is cut out. The upper row 30A continues at full capacity down to about 45 per cent load, but below this load the two rows 30A, 30B provide an equal share of the fuel until at 20 per cent load the row 30B is cut out. The fan 32 is provided both with speed control and damper regulators, which may be actuated manually or, alternatively, automatically in known manner in response to a steam flow - air flow ratio controller, to supply the required total air and fuel to the furnace. The firing rate of the furnace may also be controlled by hand or by means including control apparatus responsive to steam pressure and further apparatus responsive to steam flow which, by exerting an overriding action rendering the first control ineffective as regards the burner 30A from 45 per cent load to full load, maintains a uniform delivery of fuel and air to said burners 30A. The invention is applicable to boilers fired with liquid or gaseous fuels. in which case the supplies to the several rows of burners are controlled in synchronism with the primary air dampers 42C.
