Title: Control devices and systems for the throttle valves of internal combustion engines
IPC: F02D9/00
Filed: 1945-02-07
Abstract: 603,157. Fluid-pressure servomotor-control systems. BENDIX AVIATION CORPORATION. Feb. 7, 1945, No. 3145. Convention date, Nov. 2, 1943. [Class 135] The throttle of an internal combustion engine is controlled by a fluid-pressure servomotor boost control in which the control valve is responsive to the setting of the manual control device and to a member responsive to induction pressure, and atmospheric pressure and temperature, and the movement of this member is limited in its opening effect on the throttle by an adjustable abutment, and a second abutment which limits the movement of the control valve is dependent in its position on the opening of the throttle valve. In an aeroplane engine, actuation of the pilot's control lever 1 towards the position shown in dotted lines causes a direct opening movement of the throttle valve 19 through a link 3, lever 5, shaft 6, ]ever 11, floating lever 12, link 13, bell crank 14, shaft 16, lever 17, floating lever 101, and link 18. At the same time, the datum of the control valve 40 of the fluid pressure boost control is reset through a lever 8 carried by the shaft 6, link 20, a lever 24 adjustably connected to link 20, shaft 25, cam 27, lever 30, floating lever 36, and link 39. A stop 9 is provided for lever 8. The induction pipe pressure is applied through a pipe 60 to the inside of a bellows 57 provided with a moving end wall 61 which is common to a second, partially-evacuated, spring-loaded bellows 58. Movement of the end wall 61 is communicated through a link 37 and floating lever 36 to the valve 40 which controls the flow and exhaust of pressure fluid to the two ends of a spring-loaded servo-piston 52. The piston is connected to the throttle through a link 63 and the floating lever 12. An adjustable stop 64 sets a limit to the collapsing of bellows 57 and so cuts out the automatic control of the throttle below a predetermined induction pipe pressure. A second stop 66 is provided in bellows 58 to engage the opposite side of wall 61. As the throttle opens, an arm 67 on bell crank 14 engages and pushes over a lever 68 carried on an adjustable eccentric pin 69, and lever 68 advances a stop 76 which prevents valve 40 from assuming the position in which pressure fluid is supplied to the servo-piston to open the throttle further. An over-riding manual control of the throttle is provided by a lever 100 which is connected to floating lever 101 through a link 105, and by adjustment of lever 100 the operation of the automatic control can be varied. Specifications 449,258, 572,647 and 573,691 are referred to.

Title: Improvements in or relating to combined harvesting and threshing machines
IPC: A01D41/00
Filed: 1929-01-30
Abstract: 324,809. Jackson, L. Mellersh-, (Caterpillar Tractor Co.). Jan. 30, 1929. Thrashing - machines.- The thrashing mechanism of a combined harvesting and thrashing machine is supported by and contained in a tubular metallic shell 21, preferably corrugated. A tubular axle 8 carried by main wheels 6, 7 supports the shell and also balance beams 9, 10 for the header 13 of the harvester. A conveyer 14 carries the cut heads from the knife bar to a spout 16 that discharges them through an opening 29 in the side of the shell 21 on to a conveyer 31. This conveyer carries the heads to a beater drum 37 and concave 46 supported by the shell 21 and working through a bulkhead 26 therein. Spiked drums 44, 47 assist in carrying the heads to the beater and delivering the thrashed material therefrom. This material is thrown past a baffle 49 on to a straw walker 51 comprising a series of parallel strips 52 having serrations on the upper edges and adapted to be oscillated by eccentrics 55. The grain falls through the shaker on to a screen 66 through which it passes to a conveyer 67 in a longitudinal trough 64. A transverse conveyer carries the separated grain to an elevator 71 which lifts it to a transverse conveyer 73 that distributes it across an agitated clearing screen 77 in the upper part of a grain bin 72. The good grain falls through the screen to a hopper 83 leading to a discharge spout 86 and sacking shoot 88. Seeds that fail to pass through the screen fall through shoots to the brake drum again. The separation of the grain is assisted by air blasts through the screens from a blower 101.

Title: Improvements in and relating to methods of preparing silicone resins
IPC: C08G77/06
Filed: 1945-02-08
Abstract: Heat hardenable silicone resins are prepared by dissolving a mixture of methyl chlorosilanes (which may include silicon tetrachloride), containing an average of more than 2 chlorine atoms per silicon atom, in an aromatic hydrocarbon and slowly adding the resultant solution to a hydrolysis medium comprising an aliphatic alcohol containing 4-8 carbon atoms, an aromatic hydrocarbon and an aqueous solution of hydrochloric acid containing at least 35 per cent by weight of hydrogen chloride. The concentrated acid phase which may be separated from the hydrolysis medium may be re-used if desired, with addition of water, for further hydrolyses.  The amount of concentrated acid in the hydrolysis mixture should be suffient to furnish more than enough water for the hydrolysis.  Gaseous hydrogen chloride given off in the process may be recovered in the practically anhydrous form.  In the examples: (1) a mixture of 59.4 molar per cent dimethyldichlorosilane, 22.8 molar per cent methyl trichlorosilane and 27.8 molar per cent silicon tetrachloride is dissolved in toluene and slowly added to a mixture of toluene, n-butanol and concentrated hydrochloric acid, the mixture stirred and allowed to separate into two layers.  The upper layer of resin dissolved as butanol and toluene was separated, washed with water and centrifuged to remove gel formed during the hydrolysis; (2) the lower aqueous acid layer from example (1) is used for a further hydrolysis; (3) a resin prepared according to the invention was washed, freed from gel and "precondensed" by the method described in Specification 585,628. Specification 585,627 also is referred to.

Title: Improvements in, or relating to apparatus for the treatment of water and other liquids
IPC: B01J49/00
Filed: 1946-02-04
Abstract: 607,433. Fluid-pressure servo motor-control systems. FROUDE, R. H. Feb. 4, 1946, No. 3466. [Class 135] [Also in Groups I and II] In liquid-treating apparatus the flow of liquid operates a pulsating member or a meter whereby electrical impulses in frequent succession are created to drive a stepby-step motor and thereby a drum, disc or series of discs constituting a switching mechanism to effect a cyclic function or cyclic functions at intervals governed by the quantity of liquid flowing through the apparatus. In watersoftening apparatus indicated by Figs. 1, 6 and 7, the pipe supplying the water is fitted with a venturi or similar differential pressure device 13 connected to a pulsator 14 through a solenoid-operated valve 16. Water entering the valve through an opening 17 is led by a connection 20 to one end of a diaphragm 15 and moves the diaphragm and a rod 29 whereby a stop 28 acts to tilt a mercury switch 25 causing the energization of a solenoid 23. The solenoid moves a piston 23, whereby the liquid is led to the other side of the diaphragm. Movement of the diaphragm, through stop 27 tilts the mercury switch so that a solenoid 24 is energized and the piston is moved back to its former position. The diaphragm continues to pulsate while the liquid is flowing, and the reciprocation of the piston acts through a pawl- and-ratchet 33 to rotate by steps a drum 34. The drum comprises coaxial discs each of which is partly formed of conducting material and is engaged by a spring finger connected to a source of electric current. The drum thus determines the energization of five solenoids which control five pilot valves, in turn controlling valves 1 to 9 and a byepass valve 78. The drum 34 instead of operating the valves through electric means may operate them by cams or like means. As an alternative to a differential pressure device to operate the pulsating diaphragm, a meter may be provided to operate a change-over or pilot valve to direct water pressure to alternate sides of the diaphragm, or the meter may make electrical contacts to give the impulses required to drive the step-by-step motor.
