Title: Improvements in and relating to starter test stands
IPC: G01L3/18
Filed: 1945-06-20
Abstract: 596,250. Dynamometers. JACK & HEINTZ, Inc. June 20, 1945, No. 15767. Convention date, June 29, 1944. [Class 106 (ii)] A dynamometer test stand comprises a base, quick-release clamping means for clamping a starter thereon, a shaft on the base arranged for driving engagement by the starter, a brake drum on the shaft, a brake shoe plate revolvably associated with the brake drum, and a torque measuring device connected to the brake shoe plate and the base. The base 1 has a cylindrical head 2 carrying a reversible mounting plate 3 with dowels 6, 6<1> arranged to fit different sized starter flanges. The starter is clamped in position by arms 7 held in position by the action of a spring-operated ball detent 10, Fig. 4, and a cam 12. When a shaft 14 is rotated the cam surface 12 disengages itself from the heel 13 and a back cam portion 22 swings the arm 7 outwardly. A freely rotatable shaft 27 carries a brake drum 35 at its rear. A floating bearing 37 on the shaft 27 carries a brake assembly plate 38 with brake shoes 39, Fig. 2, in braking relation with the drum 35. The brake shoes 39 are brought into contact with the drum 35 by the action of a lever 44, Fig. 3, operated by a flexible cable 45 controlled by a handle 46. This handle is provided with a scale to facilitate the setting of pre-determined loadings. Fine brake adjustments may be made on an adjusting nut 51. A torque meter 57 is connected between the base and one of a pair of torque arms 40, 41 attached to the brake assembly plate. A tachometer 60 may be attached through gearing 62, 31 to the shaft 27.

Abstract: 650,189. Tipping-apparatus for unloading vehicles. BABCOCK & WILCOX, Ltd., and WRIGHT, R. B. June 14, 1948, No. 15922. [Class 78 (iv)] A side support for a wagon in a tippler comprises a hollow beam housing a rotary shaft extending longitudinally of the beam and provided at locations spaced longitudinally of the beam with pairs of threads of opposite hand, nuts in operated engagement with the threads and links adapted to form a connection to the frame of the tippler and pivotally connected with the nuts. A side support for a wagon 2, Fig. 1, in a tippler comprises a beam 20 arranged to be moved towards and away from the side of the wagon by manually operated means. The beam 20 comprises (Fig. 5) facing channel irons 22, 23 joined by a tront plate 24 and carrying bearing plates 29, 28 adapted to bear respectively against the flanges 36 of brackets 26 and on rollers 27 supported by brackets 25, the brackets 26, 25 being secured to the tippler rings 1. Extended portions of the plates 28, 29 are supported by brackets 52. A shaft 31, Fig. 3, mounted in the beam 20 carries two threaded portions 33 each comprising oppositely handed threads 35, 36 engaging nuts 40 guided by slides 41 in a slideway 42 (Fig. 5). A pair of vertically-spaced links 45 joins each nut 40 to a pivot 60 on one of the tippler rings 1 so that on rotation of the shaft 31 by a hand wheel 34 the beam 20 is moved inwardly or outwardly, being shown in two different positions at the left and right hand sides of Fig. 3. The beam 20 is faced with rubber blocks 21 mounted on plates 55 sliding in retaining guides 56, 57. The wagon 2 is held in the tippler by two transverse beams 4, Fig. 1, engaging the upper edges of the sides of the truck through wooden blocks 6 faced by rubber blocks 5. The beams are normally held down by springs 10 connected through turnbuckles 12 to the tippler rings at 13 and connected at 9 to hooks 8 on the beams 4. When the springs 10 have been slackened by the turnbuckle 12 and disengaged from the hooks 9, the beams 4 may be raised by cables 14 passing to drums operated by a single crank. The blocks 6 may be suspended from the beams 4 by a pair of pins on each block engaging in vertical slots in a pair of parallel links hanging from brackets on the beam, so that the blocks 6 may slide relatively to the beam. Balance weights 53 on a beam 54 serve to counterbalance the beam 20. The movable side support may be fitted to an existing tippler.

Filed: 1947-06-18
Abstract: 635,245. Automatic control systems for aircraft. ANDREWS, W. A. June 18, 1947, No. 16139. [Class 38 (iv)], The speed of an aircraft, measured by a pitot-tube, is prevented from exceeding a limiting value by control of the propulsive thrust of the power unit. As shown, Fig. 1, the pressures in tubes 10a, 10b are dependent on the aircraft speed and static atmospheric pressure respectively. The evacuated capsules 12, 17 are subjected to the pressures in 10a, 10b and the potentiometer arms 13, 18 are positioned accordingly to produce an input signal to the amplifier 26 the output of which is zero at indicated air speeds below the maximum value. In a modification (not shown) the control signal may correspond with the mach number above a limiting value. The output of 26 is applied to control the fuel supply to the injectors 41, Fig. 4 ; the solenoid controlled valve 50 positions the swash-plate 42 and reduces the stroke of the fuel pump 37 and the fuel delivery at the injectors in accordance with the output of 26. In addition, when the amplifier output rises above zero, the solenoid 55 closes the switch 54, and if the fuel pressure is low enough to permit switch 54 to close then the valve 53 is set to allow the pump 61 to supply the hydraulic ram and drag flaps 34 are moved increasing the aircraft air resistance. In a further modification (not shown) the engine thrust is lowered by a reduction of the area of the jet pipe nozzle.

[Class 82 (ii)] In a sink-and-float process of separating materials by the use of a heavy medium consisting of a substantially stable suspension, the circulation of medium to and from the body of medium in the separating vessel is controlled by admitting the medium at a determined rate and medium from the top of the body is removed at a determined rate by pushing or lifting accurately measured amounts of medium at determined intervals, outlet means for the medium being provided from the bottom of the body for the overflow or outflow therefrom at a rate equal to the admission rate less the sum of the top removal rate and the rate of removal of medium adhering to the separated particles, and the outflow or overflow rate being varied by varying the amounts pushed or lifted successively from the upper part of the medium in the separating vessel. The heavy medium is fed at 9a into a tank 9 and is fed therefrom at a determined rate at 10 into the separating vessel 1 below the surface 8 so that it divides into two streams, one flowing gently upward and then across and the other causing a gentle downward current and overflowing at the weirs 11. Sunk particles are removed by an elevator 4 and the float material is discharged over the boom 23 into a shoot 6. The medium is removed from the upper part of the surface 8 by a paddle wheel 22 rotatably mounted above the extension 24 constituting a trough the bottom 25 of which is concentric with the wheel 22 which has a large number of blades 27 attached to a hub 28, Fig. 2, the attachment being strengthened by one or more webs 29 to which the blades are also welded. Rubber blades 30, one for each blade 27, are secured to angle bars 31 mounted on the blades and provide sealing means for the paddle blades at both the side edges and tips of the blades and the speed of the paddle can be adjusted by the variable - speed drive 39. Additional paddle wheels 22a, 22b, 22c all driven from the same source as the wheel 22 may be provided, the wheel 22a, which has four blades 32 secured to a drum. 33, immersing the ore to be treated which is fed from a shoot 5, the wheels 22b, 22c having four long blades 36 secured to hollow bosses 37 and strengthened by webs 38 conveying the float material across to the trough 24. The webs 29 on the wheel 22 and the webs 38 on the wheels 22b, 22c are in line with each other and so divide the float material into lanes. The present invention is particularly adapted for use with the process and apparatus described in Specification 547,099.
