Title: Improvements in gating the input to an integrator
IPC: H03M1/00
Filed: 1966-04-15
Abstract: 1,128,408. Integrators. SOC. NATIONALE DES PETROLES-D'AQUITAINE. 15 April, 1966 [15 April, 1965], No. 16728/66. Heading G4G; In apparatusfor initiating and terminating the operation-of an integrator in response to an electric analog input signal, the latter is applied to a voltage/frequency converter- 2 exciting a gate 9 connected to the-integrator (not shown), and a pulse counter periodically zeroized by clock 8. For zero or preset input level a referencefrequency is delivered to substantially fill the counter, and any increase overflows to trigger circuit 4, closing gate. 6 and opening gate 5 whereby clock pulses trigger circuit 7 toopen integrator gate 9, and after each counting period counter 3. returns to zero, trigger 4 is restored, gate 5 closes and gate 6 opens so that trigger 7 is pulsed to close gate 9. Thus on cessation of the input-signal, integration ceases at the end of a counting period. In a modification (F g. 2, not shown) the input converted to frequency signals operates a pulse triggered . vibrator from whose input a RC integrator circuit reconverts a voltag? at predetermined level for zero input, and increases for rising input to operate a threshold trigger to open a gate-admitting clock pulses to a trigger changing over to-open a gate connecting the frequency converter output to an integrator (not shown). On cessation of signal, the threshold trigger restores to open a further gate allowing clock pulses to close the integrator gate.

Title: Improvements in or relating to copy-milling machines
Inventor: GAVED CLEMENT
IPC: B23Q35/00
Filed: 1949-06-30
Abstract: 673,976. Copy-milling. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. June 21, 1950 [June 30, 1949], No. 17371/49. Class 83 (iii). A copy-milling machine having a tracer 6 and cutter 7 movable in a complete circuit round a model 1 and work-piece 2 respectively is provided with means, operative at will, for automatically reversing the sense of movement round the circuit when the tracer reaches one or other extreme of a part only of the circuit, the machine functioning in its normal manner between such automatic reversals. When the reversing means is in operation, one side of the work can be supported to prevent deflection under tool pressure and the tool movement is confined almost solely to that necessary for shaping the other side of the work. The model 1 and work, such as a turbine blade 2, are mounted on a table 5, or on separatelymovable tables, and the tracer 6 and tool or tools 7 are mounted in a head 8 having automatic mechanism capable of copying by contours. For copying one side of a model, however, reciprocating traverses of the table 5 are controlled by trips 12, 13 which, through a switch 15, solenoid 16 and pawl and ratchet mechanism, operate a rotary reversing switch 11. Vertical displacement of the head 10 is effected by a solenoid 18 acting through a pawl and ratchet on a feed screw 17, the solenoid being returned by a weight 42 and the ratchet having an adjustable mask for adjusting the feed. The solenoid 18 may be operated from the circuit of the switch 15 so that vertical feed is given after each reversal of the table but, preferably, is operated by a separate circuit arranged, if desired, to operate the solenoid at every second reversal and controlled by trips 20, 21 and a switch 19. To allow extended traverses, in order, for example to remove finished work, the trips 12 and 21 have elongated slots so that they may be shifted by turning a crank 22 through half a revolution.
