Title: A system for machine counting operations
IPC: G01L1/22
Filed: 1967-08-31
Abstract: 1,201,271. Forging. NATIONAL SCREW & MFG. CO. 31 Aug., 1967 [9 Sept., 1966], No. 39868/67. Heading B3H. [Also in Divisions G4 and H3] Apparatus for deriving electrical signals from mechanical stresses included within a predetermined range of magnitude and durations (e.g. from the main blows of a forging hammer) comprises a transducer 10 for developing voltages which vary in accordance with all said stresses and feeding an amplifier having a low-pass frequency characteristic, the output of said amplifier being inhibited for a predetermined time after the occurrence of each stress falling within said predetermined range of characteristics, so as to minimize the effect of unwanted stresses on the electrical output signal. As shown, a silicon strain gauge 10 is mounted on a forging hammer and is supplied with current from a power supply 22 after stabilization by Zener diode 21 and further stabilization by Zener diode 26 and emitter follower 18. The resulting voltages are amplified by transistors 40, 50, 60; unwanted high-frequency signals being attenuated by capacitors 71, 72, 73. The waveform from transistor 60 is limited by transistors 81, 82, rectified by diode 90 and used to charge a capacitor 93. The onset of the rectified voltage switches a monostable circuit comprising transistors 102, 103 into a condition whereby transistor 103 is non-conductive and transistor 102 conductive, this condition subsisting for a period (adjustable at 111) slightly less than the interval between regular main blows of the forging hammer. Switching transistor 116 is made conductive during this period, inhibiting further charge of capacitor 93 by unwanted signals. An output pulse is thus available from transistor 103 corresponding to each main blow of the forging hammer and is fed to an electromechanical counter after amplification by transistor 128.

[Also in Group XXXV] In an automatic, weight controlled, package filling machine having means for compensating for the weight of material suspended at cut-off, the compensating means is controlled by a separate control weigher 3 arranged after the main one 2. The compensation is provided by a chain 7, one end of which is attached to the beam 8 of the main weigher while the other is carried at an adjustable height by a motordriven belt 11. The motor is driven for a predetermined time in the appropriate direction upon the closure of a relay 32, which is energized when a summing device 31 registers a given accumulation of small errors in weight, detected by the weigher 3. Large errors cause the rejection of the package by a device 4, energized when relay 26 or 27 closes. As shown, the weigher operates on a variable, differential, voltage transformer 15; the phase sense of its output, indicating plus or minus error is detected by a phase bridge 21 while the magnitude of the voltage, a function of the error, is detected by voltage sensitive relay. unit 22... 25. These employ four-layer semiconductor diodes, and are described (Fig. 2, not shown). It is stated that the system may employ impulses derived from frequency modulation instead of variable voltages, and that one control weigher 3 may serve several main weighers by suitably switching its output.

In an axial-flow compressor, for example for a gas turbine vertical lift engine, comprising a casing 11 containing a rotor shaft 16 provided with a number of axially spaced rotor discs 17 each having a peripheral flange 20 extending axially upstream and downstream of the respective disc, a number of angularly spaced rotor blades 27 carried by the peripheral flange, and a number of rows of angularly spaced stator blades 30, each row of stator blades carries a sealing ring or sealing ring assembly which extends into both the adjacent annular spaces 25, 26 between two adjacent periperal flanges and the shaft, and is in sealing relationship with the radially inner surfaces of both adjacent peripheral flanges. The sealing ring assembly shown, which prevents reversal of flow across the stator blades, comprises a removable sealing ring 40 and two axially spaced removable sealing rings 31, 32, each constituted by two half rings dowelled together. The sealing rings 31, 32 are secured to the shroud 33 of the respective row of stator blades by means including dogs or cross-keys (not shown). The rings 31, 32, 40 carry sealing surfaces 34, 35, 36, 41 contacted by ribs 23, 24, 37 which cut into the softer material of the sealing surfaces. The sealing surfaces 36, 41 face in the opposite direction to the sealing surfaces 34, 35 to reduce or eliminate the effects of radial expansion and contraction on sealing. The pumping of large amounts of air into the spaces 25, 26 is avoided since these spaces are largely occupied by the sealing rings 31, 32. The compressor may be largely fabricated of synthetic resin material.
