Abstract: 598,162. Cooling fans for aero-engines ; variable-pitch propellers. FAIREY AVIATION CO., Ltd., and FORSYTH, A. G. Dec. 10, 1945, No. 33377. Convention date, Feb. 2. [Classes 4 and 114] [Also in Group XXVII] An aircraft engine 10, Fig. 1, is cooled by a fan 18 rotatably mounted on a cylindrical bracket 11 attached to the front face of the engine, the fan 18 and a stator 17. being positioned with their planes rearwardly of the said engine front face. Sleeve 25 is secured to the propeller shaft 19 and carries a gear 34 which meshes with a pinion 46 attached to a spider member 51 which carries in slots 52 the centrifugal clutch weights 54 which when they have reached a predetermined speed, governed by a spring 61, contact and drive the gear 55 which meshes with teeth 63 on the fan hub 62 so driving the fan 18. A variable-pitch mechanism for the propeller 22 consists of two gears 35 and 41, of the same diameter, but having a different number of teeth, driven by gears 33 and 28 on the sleeves 25 and 27 respectively, the sleeve 29 carrying the teeth 30 for actuating the pitch-change worm gear 24. When it is required to change the pitch of the propeller, the gears 35 and 41 are clutched together so giving relative rotation between the sleeves 25 and 29. Four sets of gears are supplied, two having most teeth on the gear 35 and two having most teeth on the gear 41, so that pitch may be altered in either direction. An electric motor 42 is supplied for feathering the propeller. The modification shown in Fig. 6 has a fan drive similar to the abovedescribed embodiment, but the fan in this case is supported by two bearings 74 and 75 mounted on the sleeve 73 secured to the propeller shaft 72. The housing 87 held stationary by the arm 88, also holds the variable-pitch mechanism which consists of two equal diameter gears 85 and 101 with different numbers of teeth connected with a centrifugal clutch spider 92 and clutch outer member 99 and driven by gears on the sleeves 73 and 103 respectively. To alter the pitch, plate 90 is moved to the left, thus allowing the clutch to operate and run the gears 85 and 101 at the same speed to give relative rotation between the sleeves 72 and 103. To cease operating the pitch change, the plate 90 is moved to the right, thus by means of the levers 98 breaking connection between the gears 85 and 101. Specification 597,931 is referred to.

Title: Method and apparatus for feed rate control of spindle-related
IPC: G05B19/416
Filed: 1970-07-10
Abstract: 1317167 Programmed control of machine tools ALLEN-BRADLEY CO 10 July 1970 [10 July 1969] 33715/70 Heading G3N In a numerical control system the relative tool traverse velocity is controlled in dependence on a signal having a value proportional to spindle speed which is modified by or combined with, the ratio of desired vectorial velocity of the tool to the vectorial departure. As shown, a machine having a spindle 10 and tool 10a is controlled by incremental or absolute command information read into a distributor 12 by a tape reader 11. The incremental position signals X, Y and feedrate PR, expressed as inches per revolution of spindle 10, are fed to a contour generator 20 and a feedrate generator 18, respectively. An encoder 15 has a shaft position transducer 16 which provides trains of square pulses over lines A, B, at a frequency proportional to the rotational speed of the spindle 10, which are converted in a logic unit 17 to a single pulse train f 0 , which is fed to the feedrate generator 18. The pulse output of the generator 8 has a rate proportional to the multiple of the frequency f 0  and a value proportional to the reciprocal of a vectorial distance D. The value D is calculated in a circuit 19 responsive to the values X, Y. It is stated that alternatively, the value D can be pre-computed and stored, or the feedrate stored as a feed-rate number FRN and the output of circuit 18 is then a train of pulses at a frequency proportional to the product f 0 . FRN. The output from generator 18 is fed to a contour generator 20 providing metered pulses Px, Py to X and Y axes control 22 operating machine drives 23 having position feedback from transducers 24, 25. In an alternative embodiment the output of the shaft position encoder is multiplied by the programmed IPR. and subsequently by the reciprocant of D, from a computing element fed from the contour generator to effect the equivalent of the multiplication by the FRN.
