IPC: F02P15/12
Filed: 1918-03-12
Abstract: 120,229. M-L. Magneto Syndicate, and Hulse, C. E. March 12, 1918. Magnetos, driving. - Trip mechanism for ignition magnetos comprises a driven member B and a driving member C coupled together by springs O. The member B has an annular flange D which is cut away at two places to form recesses E into which enter radial arms F on the member C; the recesses E are wider than the arms F so that lost motion may take place. A pair of radial spindles G are carried by the member B and are pressed inwardly by a spring ring H. Stop rollers J are mounted freely on these spindles and at low speeds engage in turn against a fixed abutment L carried by the magneto. The springs are thereby stretched until a cam P on the member C raises the stop roller from the abutment L, producing rapid rotation of the magneto. At higher speeds, the stop rollers move out by centrifugal action and do not engage the abutment L.

Title: A new or improved automatic control valve for air and other fluids
IPC: F16K17/164
Filed: 1941-10-10
Abstract: 552,324. Fluid-actuated valves. ALLEY & MACLELLAN, Ltd., and DAVIES, W. D. Oct. 10, 1941, No. 13116. [Class 135] A valve device opened under hand control and adapted to close automatically if the pressure of the fluid drops below a predetermined value and then remaining closed until the hand control is operated has the main valve actuated by a piston exposed on both faces to inlet pressure when the valve is closed, one face being connected to atmosphere through an auxiliary valve to open the main valve. In the form shown in the Figure a lift valve member 16 with a fibre facing 15 to co-operate with a removable seating 14 is rotatably connected to a spindle 17 fixed to a piston 20. This piston which is loaded by a spring 43 works in a liner 21a and is formed with a sealing face 24 adapted, when the valve is open, to engage a fibre washer 23 beneath a cover 22 or a ground face on the cover. The auxiliary valve 30 actuated by a push 39 against the action of a spring is adapted, in the position shown, to connect the space above the piston to the inlet by way of passages 28, 42 in the casing and an axial passage 33, port 34 and annular groove 35 in the valve member. When the knob is pressed this connection is interrupted and the space above the piston connected to atmosphere by way of passages 28 and 33 port 36 and flats or grooves 38 in the spindle. As the piston moves to its upper position it obturates the passage 28 and an extension 27 on the spindle 17 lifts a spring- loaded vent valve 26 to prevent the accumulation of pressure above the piston due to leakage past the piston which accumulation would cause premature closing of the valve. A hinged cover 40 prevents accidental operation of the auxiliary valve. In a modification the lift valve is replaced by a sluice valve.

Title: Improvements relating to devices for indicating and measuring the level of liquids
Inventor: BONUDY JAMES REILLY
IPC: G01F23/24
Filed: 1950-05-25
Abstract: 678,863. Electric indicating systems. EVERSHED &; VIGNOLES, Ltd. May 25, 1951. [May 25, 1950] No. 13200/50. Class 40 (i). A liquid level measuring and indicating device comprises a plumb bob, partially immersed in the liquid and raised and lowered by an electric motor, which controls, in accordance with its position relative to the liquid surface, a current acting in opposition to a constant current, the combined effect of the currents exciting the field of the motor, which restores the plumb bob to its datum position and operates a liquid level indicator. In Fig. 1 a conductive plumb bob 3 is suspended in the surface of a liquid 1, within a metal tube 5 earthed through the liquid body by a connecting cable 4 wound on a drum 7 which is rotatable through gearing by a D.C. motor 10 also driving an indicator 15. The motor armature is energized by the bridge rectified output of the secondary 17 of a multiwound power transformer 18, and the motor field is energized by a constant current from the rectified output of winding 24 in opposition to a variable current from a rectifier energized from winding 26 through a circuit comprising the plumb bob, the resistance of the liquid between the bob and its surrounding tube, the cable, and a connecting slipring 9. When the bob is immersed to a datum level, the motor field energization is zero, and variations in liquid level unbalance the opposed field currents so that the motor is energized to raise or lower the bob until it is again immersed to the datum level, and reset the indicator. In a modification, Fig. 2 (not shown), a single transformer secondary supplies a first rectifier energizing the motor armature and a constant excitation field winding, and a second rectifier in series with the plumb bob and liquid circuit to excite a second field winding in opposition to the first. When the liquid is non-conducting, the plumb bob comprises a temperature variable resistor, or an inductance variable by a magnetic float, either of which is responsive to the degree of immersion, and is connected in series with the variable field excitation rectifler through a double suspension cable and sliprings. Specification 409,102 is referred to.

Patent GB-134738-A (GB)
IPC: G11B3/095
Abstract: 134,738. Wade, H., (ãolian Co.). March 11, 1919. Returning sound-box to starting-point; raising, lowering, and positioning sound-boxes.-In a repeating-device for gramophones &c., the tone-arm is lifted at the end of a reproduction by the engagement of a driving-roller beneath a curved platform secured to the tone-arm, and the frictional contact of the driving-roller returns the tone-arm to starting position. The driving-roller is mounted on a tilting shaft controlled by an electro-magnet, which is energized at the end of a reproduction, and is de-energized after the return of the tone-arm, by switches actuated by the tone-arm. Fig. 1 is a plan of the mechanism with the top-plate removed, Fig. 2 is an elevation, and Fig. 6 shows a detail of the switch-actuating device. A bent rod 12 secured to the tone-arm 4 projects through, a slot in the cover-plate 2 and carries at its lower end a curved platform 14. Beneath the platform lies a roller 21 mounted on a shaft 19 which has its bearings in a yoke 16 pivoted on pins 17 to fixed pillars 15. The other end of the shaft 19 carries a friction roller 20 lying over the upper face of a toothed wheel 8 which forms part of the driving-gear between the spring motor and the turntable spindle 9. An arm 22 on the yoke 16 is pivoted to the core 54 of a solenoid 23, a spring 24 normally holding the core in its outer position, and maintaining the roller 20 out of engagement with the wheel 8. At the end of a reproduction, the tone-arm engages a switch-actuating member 39 and closes a switch 27 in the circuit of the solenoid, which thereupon attracts its core 54 and tilts the yoke 16. The roller 21 engages and lifts the platform 14, thus raising the sound-box off the record. The roller 20 engages and is rotated by the wheel 8 and the platform 14 is thus moved in a horizontal direction, returning the sound-box and tone-arm to its starting-position. Meanwhile the solenoid circuit is maintained through a hold-on contact carried by an armature beneath the solenoid. The holdon contact is in series with a normally-closed switch 30, and when the tone-arm reaches the starting-position, the contacts 30 are opened, the solenoid de-energized, and the sound-box lowered on to the record. The core 54 moves in a cylinder with an air-escape hole in its base, thus cushioning the descent. The switch-actuating members for each switch comprise a horizontal slidable rod 38 with an upturned end 39 pressed towards the tone-arm by a spring 46. The movable switch spring 27 or 30 is carried by an arm 33 pivoted at 34. The rod 38 passes through an oval hole in a vertical pin 36 which slides in the vertical direction through the arm 33. A spring 40 presses the pin 36 downwards and gives a frictional grip between the arm 33 and the rod 38. This grip may be released by depressing a plunger 43 connected by a lever 41 to the lower end of the pin. The rods 38 can thus be adjusted to the points for starting and finishing a reproduction.
