Title: Improvements in or relating to pressure intensifying devices
IPC: B23Q3/08
Filed: 1962-07-25
Abstract: 955,889. Machine tool details &c. E. M. TOROSSIAN. July 25, 1962 [March 30, 1962], No. 28627/62. Heading B3B. [Also in Division F1] A pressure intensifying device for moving the jaw J, Fig. 2, of a vice comprises a pneumatically-operated piston H, Fig. 1, operating in a cylinder A which has a movable piston E in its head portion B, an hydraulic cylinder C which caps the cylinder head B and seats on the fixed jaw I, a plunger G connected with the piston H and extending slidably through the movable piston E for producing a high pressure in the cylinder C and thereby operating the jaw J, and an air supply connection 5 to the cylinder A for withdrawing the plunger and removing the clamping pressure. A rotary valve, which is mounted directly on the cylinder A, has ports 5 2 , 6 2 , Fig. 5, in its casing 11 which communicate with ports 5, 6, Fig. 1, in the cylinder, and by operation of a rotatable spring-urged plate 8, one of the ports 5 2 , 6 2  can be connected with an air supply at 17 and either one or both connected with atmosphere through a central bore 16 depending upon the position of the plate; a limit stop 19 and indicating means 15 are also provided. After the piston E has been moved by air supplied to the port 5 to displace hydraulic fluid from the space F in front of the piston E into the cylinder C to cause the initial clamping of the hydraulic cylinder C against the fixed jaw, the plunger G is advanced by air supplied to the port 6 so that it isolates the hydraulic cylinder C from the space F as it enters the bore 3 of the rod D connecting the head B with the movable jaw so that, by compression of the fluid, it moves the head B to the right to produce the final clamping movement. When the valve is operated to unclamp the vice by connecting the port 6 to atmosphere and the port 5 with the air supply, the sudden decompression which occurs results in the various sealing rings disposed between the moving parts being restored to their normal shape from their temporarily deformed state during the clamping stroke. The member E may be spring-returned. Specification 955,888 is referred to.

Filed: 1966-06-27
Abstract: 1,100,081. Digital phase measurement. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 27 June, 1966 [29 June, 1965], No. 28793/66. Heading G4H. The phase difference between two alternating voltages of the same frequency is digitized by means which determine a first interval extending equally on either side of a zero crossing of the first voltage, Fig. 3, and means determining a second interval extending equally on either side of a zero crossing of the second voltage, Fig. 4, and means for counting pulses between the beginnings of the two intervals and between the ends of the two intervals. The two voltages V 1 , V 2 , Fig. 2, are applied through switches 8, 9 to integrators 6, 7 the outputs of which pass to zero detectors 10, 20. The beginning of the interval for voltage V 1  is set by pulse A which closes switch 8. The integrator 6 integrates the negative shaded part of the waveform and this is then neutralized by the positive shaded part. When the output of the integrator 6 is zero, the detector 10 generates a pulse B to open switch 8. The pulses A and B are the beginning and end pulses of the interval of the voltage V 1 . Similar pulses C and D define the interval of voltage V 2 . Pulses are counted between the instants A and C and then between the instants B and D and the total count indicates the phase difference. A shaft encoder, Fig. 6 (not shown) using this principle comprises a resolver having quadrature windings the outputs of which are phase shifted and combined in such a way as to produce voltages V 1  and V 2  having a phase displacement proportional to twice the input angle. A clock pulse generator is used to derive the exciting voltage for the resolver and also supplies pulses for the interval counting. The inputs to the counter are gated in such a way that if the periods AC and BD overlap double frequency pulses are counted during the overlap.
