Title: Device for producing a pair of signals with phase displacement
IPC: H03B19/00
Filed: 1968-01-11
Abstract: 1,215,376. Pulse shaping and phase changing Circuits. MOBIL OIL CORP. 11 Jan., 1968 [12 Jan., 1967], No. 1626/68. Heading H3T. [Also in Division H2] In a system for producing a pulse train displaced in phase from an input train, e.g. for driving a synchronous motor, the input train is converted to a train of double the frequency and half the width and edges of one polarity in the train are used to define the leading and trailing edges of the output train. As shown, pulses XI from block 34 are differentiated at 36 and the negative output removed at 38. They are also inverted at 42, differentiated at 44 and the negative pulses removed at 46 so that the output of the OR gate 40 is a double-frequency positive pulse train. These pulses each cause a storage element 48 to quickly charge and this is dissipated in a contsant current discharge circuit in 50 so that sawtooth waves are produced. These are applied to a Schmitt trigger 54 to convert the waves to a square wave train each pulse of which reverses the state of a divide-bytwo bi-stable circuit which therefore provides a square wave output displaced in phase by 90 degrees from the input from 34. The two trains are applied through 62 and 60 to a synchronous motor. As described the circuit is used to control the motor in dependence upon pulses received in a sensor 10 in the fuel injection line of a diesel engine. The output of the sensor is applied via a source follower 12 and an inverter 14 to a Schmitt trigger 18 via a threshold level setter 18. The output of the Schmitt circuit operates a mono-stable circuit 20 to ensure that closely spaced pulses appear as a single rectangular pulse. The resulting output is amplified and inverted at 22, differentiated at 24 and the negative pulses removed at 26. The remaining positive pulses cause a storage circuit 28 to rapidly charge and this charge is dissipated in a constant current circuit 28 to produce sawtooth waves. These waves are centered about a zero level in 32 and applied to a Schmitt trigger to provide the square wave XI referred to above. Conventional transistor circuits for use in the blocks are described with reference to Figs. 2, 3 and 4 (not shown) which respectively include the combinations of blocks as indicated in Fig. 1.

Abstract: 113,443. Fulpius, E. Feb. 13, 1917, [Convention date]. Fluid relays.-Apparatus for moving a piston in a cylinder 2, Fig. 1, in order to control turbines &c. comprises a small pump 1 and a larger pump 3, which may be mounted on the same driving shaft, the small pump constantly supplying liquid to make good the leakage of the cylinder 2 and its slide valve 7, the surplus supply escaping through a valve 13, while the liquid from the pump 3 escapes through passages formed by grooves 6. The slide valve 7 is moved from the position shown by a rod 12 operated by a regulator, causing disks 5 on the valve spindle 8 to close the grooves 6, so that the liquid from the pump 3 is forced to raise a non-return valve 10 and pass to the cylinder 2, the motion of the piston in this cylinder acting through a lever 11 to return the valve 7 and disks 5. In a modification liquid supplied by the pump 1 acts on a piston 8, Fig. 2, in a cylinder 16 to keep a disk 5 in the position shown against the action of a spring 13, a weight or hydraulic pressure. When the slide valve 7 is moved, a slide 14 is operated to shut off the supply to the cylinder 16 and open an exhaust 17, the disk 5 being thereby allowed to close the escape 6' for the liquid from the pump 3. When tl e diameter of the piston 8' is less than that of the disk 5, the latter can act as a safety valve. An alternative method for controlling the disk is by means of an electro-magnet controlled by a contact worked by the slide valve 7.
