Title: Improvements in or relating to valve gear for percussive tools
IPC: B25D9/20
Filed: 1936-06-05
Abstract: 458,656. Valve gear for percussive tools. MOSS, E. W., 75, Victoria Street, Westminster.-(Ingersoll-Rand Co. ; 15, Exchange Place, Jersey City, New Jersey, U.S.A.) June 5, 1936, No. 15762. [Class 122 (ii)] A percussive tool is provided with a fluidactuated lift valve arranged at the rear coaxially with the piston. The valve is provided with holes through which pressure fluid is supplied to the inlet passages and which terminate at a face on which the valve seats. A series of plates 44 ... 47 are shaped to form a valve chamber in which the valve 49 reciprocates. The valve is guided by a bushing 30, and, in the construction shown, has an external flange 50 with actuating areas 51, 52 thereon to which pressure fluid from the cylinder passes to help actuate the valve. The kicker passages 53, 54 enter the cylinder on either side of the exhaust port 26. Fluid pressure is supplied to a central valve chamber 55, and passes through passages 57, 58 in the valve to either end of the cylinder. The front and rear ends 59, 60 of the valve 49 serve as holding-areas. The plates 44, 47 have surfaces 61, 62 upon which the valve seats. The weight of the valve is reduced by the passages 57, 58 and the chamber 55 therein. The valve is operated at low lift to reduce wear, the fluid being supplied by a group of inlet passages 65 and a central bore or passages 66. The valve shown is reversed by release and the pressure on surfaces 51, 52. In a modification, the pressure fluid passes to the valve chamber through a passage and grooves in the plates forming the casing to a pair of valve chambers on either side of the valve flanges. In a further modification, the valve has a central supply chamber fed through a central passage in the bore of the tool, or by parallel passages in the casing. The external flange is dispensed with and the valve is reversed by the fluid suction in the valve passages.

The control flow may be angled in the forward direction by 5 degrees. Control flow pressure may be increased when the device functions in the reverse flow state. The device may be used in combustion systems or flame stacks to impart swirl to forward flowing fuel but act as a flame trap if flash back occurs.

Locking means are added to the coil-handling device of the parent Specification to hold the arcuate rack member 12 in any position relative to the control head 11. As shown, the locking means 11<1> comprise a double-acting hydraulic ram pivoted at 154 to the control head and at 159 to one of the links 13 which support the rack member. The ends of the ram cylinder are interconnected in an hydraulic circuit which includes also a reservoir 167, and solenoidoperated valves 162, 163 controlling ports at either end of the cylinder are normally biased open and may be closed either manually from the crane cab or by a switch 173 actuated when a hook in the shackle 14 becomes slack. In the latter case means are provided to hold the valves closed when the hook is removed from the shackle. Alternatively the valves may be normally closed and connected in series with a switch 173 with a longer arm, so that such switch is always closed when a hook is in the shackle and the valves cannot be opened unless a hook is there. With this arrangement the valve solenoids may be connected in parallel with the circuits for moving the rack so that the rack is unlocked only during such movement.

Abstract: 687,459. Measuring radio-activity. BERTHOLD, R. July 9, 1951 [July 7, 1950; Oct. 20. 1950], No. 16228/51. Class 40 (iii). A scaling circuit for counting the output pulses of a Geiger tube comprises a condenser charged by successive output pulses until it reaches a potential high enough to fire a shunting gas-discharge tube. The circuit shown in Fig. 2 is such as to make all the pulses fed to the condenser 3 of the same height. The initial pulses are developed across the load resistor 6 of the Geiger tube 1 and trigger a gas-filled relay 7. A small condenser 11 discharges through the tube which then cuts off the condenser 3, which may be variable, then recharges condenser 11 lowering the potential of the plate connected to the glow tube 4. Successive pulses from the Geiger continue to lower this potential until the potential developed across the tube 4 is sufficient to fire it. Tube 4 thus fires once in say ten Geiger pulses discharging through a recording device 14. If the Geiger tube is fed with a constant voltage and is of the self-extinguishing type containing vapour the pulse levelling circuit is unnecessary, and an embodiment is described, (Fig. 1, not shown), in which the Geiger tube connected in series with the condenser 3 and the glow lamp discharges audibly through a telephone receiver. In the embodiment of Fig. 3 (not shown), shunting resistors are provided through which the condenser leaks, the arrangement being such that the glow lamp never discharges unless radiation intensity is above a certain value. Applications of this last embodiment are for indicating when the liquid in a tube interrupts a radiation beam and indicating when the radio-active contamination of a building exceeds a certain value.
