Title: Improvements in or relating to pumps
IPC: F04D13/04
Filed: 1939-01-16
Abstract: 523,836. Hydraulic couplings. MUIR, N. S., CLOTHIER, W. C., and WHITAKER, J. H. Jan. 16, 1939, No. 1389. [Class 69 (ii)] In pumping apparatus a delivery pump is operated by a supply pump which delivers part of the fluid supplied by the delivery pump to the driving turbine or the like of the delivery pump, the said turbine and pump being mounted on a common rotor. As applied to means for supplying fuel oil to the carburettor A', Fig. 1, of the engine A of an aeroplane, a centrifugal delivery pump D, which has pipe connections with the reservoir B and the rotor of which is formed with turbine vanes E, is driven by the turbine which is supplied with fluid under high pressure by a pump K driven by the engine A. The pump and turbine have a common outlet leading to a pipe G and thence to a small reservoir H which supplies the carburettor A<SP>1</SP> and also the pump K, and the relation of the tank B to the pump causes air entrained in the oil to be released. A priming pump M, a fuel flow meter N, and a pressure-reducing valve P are arranged in the fuel circuit. A non-return valve may be arranged in the pipe L. The pipes L, G and associated parts may be duplicated so that if one set is put out of action another set may be employed. In a lubricating system, Fig. 4, oil is supplied from a tank U by a rotary pump in a casing V to a pipe T<SP>2</SP> leading to a gear pump T, which delivers part of its output to drive a turbine in the casing V, this turbine and the pump being on a common rotor.

Filed: 1940-01-24
Abstract: 537,521. Testing balance of rotary bodies. KOLESNIK, N. V. Jan. 24, 1940, No. 1462. [Class 106 (ii)] [Also in Groups XX and XXXVII] Apparatus for use in balancing rotating parts of machines, without dismounting either the whole machine or the unbalanced part comprises a casing containing a pair of contacts 4, 5 in the circuit of gas-discharge or other inertialess lamp 6, one contact 4, being fixed and the other on an elastic strip 11, the free oscillation period of which can be adjusted. The apparatus is placed on a vibrating portion of the machine body 2 and the vibrating contact tuned to resonance with the vibrating machine, when the amplitude of its oscillation increases so that contact occurs at each oscillation and the flashes of the lamp illuminate a mark a placed on the out-of-balance rotating member 3, which mark, owing to the synchronism of the flashes with the rotation of the member 3, appears to be stationary. A mark b is made on a fixed part of the machine opposite the apparent position of the mark a, the machine is stopped, and the member 3 turned to bring the two marks into coincidence ; the mass 7 causing the lack of balance is then on the vertical radius of the rotating member, so that its radial position is determined. In the apparatus shown the vibration period of the strip 11 is adjusted by means of a slide 12 having a slot through which the strip passes and vertically adjustable by a screw 14. A vertical scale in conjunction with a fineadjustment scale on the knob 15 indicates the frequency to which the contact is tuned. The contact 4 is carried by a pivoted arm so that it may be adjusted until contact is only just obtained, a scale 18 indicating the relative amplitudes of oscillation of the machine.

Title: Improvements in or relating to foundry moulding machines
IPC: B22C15/10
Filed: 1929-01-16
Abstract: 328,012. Hines, L. H. Jan. 16, 1929. Moulding-machines, having an air or other fluid-operated jar-ram 7, a drawing-piston 22 operated by compressed air acting through a body of oil or other liquid an a vibrator, are arranged so that the force of the blows of the vibrator which is mounted directly below the pattern, is trans mitted in a straight line direct to the pattern-plate Air, supplied to a valve casing 43, is admitted, in all positions of the valve 42, to a valve 34 which can be opened by hand to start the vibrator 12 and is closed by a frame 28, carrying adjustable drawing-rods 31, when the pattern has been drawn free from the mould. When the handle 44 of the valve 42 is moved in a clockwise direction air is admitted to passages 51, 52, 55 and the ram 7, being in its lowest position, admits the air, via passages 56 and 57, to the rear end of the pilot valve 54 which is moved to the front, the trapped air exhausting through passages 58, 59, 60, oil trap 4, and vent 61. The valve 54 then admits air, via passages 52, 62, to the bottom of the cylinder 6, thus lifting the ram 7 and the mould &c. resting on the table 9. When the passage 58 is uncovered the air moves back the valve 54, the trapped air exhausting through passages 57 and 56, which in this position of the ram aligns with a port 57<a> leading to the exhaust passage 60. Then the air below the ram exhausts through passages 64, 64<a>. This action is repeated, until the valve 42 is returned to the middle position, the table 9 striking a rubber pad 10 on the cylinder 6. When the handle 44 is moved counterclockwise air is admitted by a passage 67 to an oil chamber 3 thus forcing oil through a feed passage, not shown, to the bottom of a cylinder 2 in which the drawing- piston 22 is arranged. This is connected by a yoke 25 and rods 26 to the frame 28 and, as it rises, uncovers additional ports in the feed passage so that the motion is accelerated. The air above the piston is exhausted through passage 73, valve 42, passage 77, and oil trap 4. When the draw is complete the mould is removed and the handle 44 returned to its middle position, thus admitting air by passage 73 to the top of the cylinder 2 to return the drawing-piston, the oil being returned to the chamber 3, which is connected to exhaust by passage 67, valve 42, passage 77, and oil trap 4. In this position oil in the trap can flow through the one-way valve 40 to the chamber 3. The vibrator 12 has the usual ports connected, through an adjustable needle valve 38 and the valve 34, to the constant air supply pipe 75 and, through passages 16, 14, 60, to exhaust. The upward movement of the frame 28 is limited by reversible stops having reduced ends, of different length, to engage holes in the frame and thus vary the length of draw.
