Filed: 1972-10-25
Abstract: 1404609 Measuring velocity INSTITUTE DE RECHERCHES DE LA SIDERURGIE FRANCAISE 25 Oct 1972 [29 Oct 1971] 49121/72 Heading G1A Apparatus for measuring the speed of a moving hot billet of the type comprising a pair of detectors spaced along the axis of motion and sensitive to the passing of the object utilises the properties of a correlation function whereby the fluctating random signal from the first sensor as the body of the hot object moves past is delayed in a shift register supplied with shifting pulses by a voltage controlled oscillator, and the signal delayed by e.g. 201 and 205 shifting pulses is multiplied by the signal direct from the second sensor, the respective results of this multiplication being passed through integrating circuits and the difference between the signals derived in a differential amplifier, whereby if the frequency of the shifting of the register exactly represents the speed of the object, 203 shifting pulses will occur between the outputs of the detectors and under these conditions, the two signals derived as described above will lie at equal distances to the sides of the peak of the symmetrical correlation function, i.e. will be equal in value, any difference in their values being utilized to amend the frequency of the oscillator, which frequency then represents the required speed. As described, a coarse and fine system is provided whereby the frequency of the oscillator is initially set to a value roughly corresponding to the speed prior to the fine operation referred to above. A hot moving billet 3 is passed by two photo-cells 1, 2 which give outputs when the leading edge of the object comes into their field of view, the outputs being taken via respective differentiators 14, 15 to respectively open and close a gate 13 to allow pulses to pass to a counter 17 from an oscillator 16 to a store 18 and a D/A converter 19 whereby a voltage is passed to control a voltage-controlled oscillator 8, the output of which provides the shifting pulses to the shift register 7 and the frequency of which thereby corresponds to the measurement of speed. The two outputs from the cells 1, 2 as the body of the billet moves past are shaped at 4, 5, 6 and the output from cell 1 is delayed in the register 7. The output from cell 2 is taken from the circuits 4-6 to two mulitplying circuits 9 where it is multiplied with the output present at cells of the register 7 corresponding to delays of 201, 205 shift pulses respectively and the outputs of circuits 9 are taken to integrators and thence to a differential amplifier 11, the output of which effects a fine adjustment of the V.C.O. 8. The speed is read out at 22 from the oscillator 8.

Title: Improvements in or relating to fuel injection pumps
IPC: F02M59/22
Filed: 1964-12-04
Abstract: 1,071,321. Fuel injection pumps. VYZKUMNY USTAV PRISLUSENSTVI MOTOR - OVYCH VOZIDEL. Dec. 4, 1964 [Dec. 5, 1963], No. 49378/64. Heading F1A. For controlling the delivery of a fuel injection pump having a rotary cylinder block 2, the pump working chamber communicates through a passage 9 with one side of a relief piston 13 which is loaded from the other side by a spring 19, the stroke of the piston 13 being limited during compression of the spring by a rigid stop 14 adjustable by means of interchangeable washers 15 of different thicknesses, and during expansion of the spring by a member 16 free to slide on the pump rotor, the position of the member 16 being determined by a governor. The pump has two plungers 3 which engage a cam ring 5 through tappets 6. Fuel enters the pump through a passage 7 and valve 8 when the plungers 3 assume their radially outermost position. At this time, the piston 13 moves to the left until a pin 17 abuts the member 16. Initially, during a discharge stroke of the plungers, the fuel to be discharged moves the piston 13 to the right until it abuts the stop 14. Subsequently, fuel is discharged through a rotating duct 10 and one of a number of passages 11. The governor comprises a member 21 which is secured to the pump rotor and carries in radial slots at least two balls 22. The centrifugal force of the balls tends to move a member 23 to the right against the action of a spring 24, the load of which is adjustable through a lever 26. When the speed of the pump rotor exceeds a certain value, determined by the load on spring 24, the centrifugal force of the balls 22 overcomes the force of this spring 24 and the member 23 moves to the right, the balls then moving radially outwardly since they bear against an inclined face of the member 23. An inclined face of the member 16 bears against the balls, and, therefore, upon outward movement of the latter, the member 16 moves to the left under the action of the spring 19. The stroke of the piston 13 is thus increased, with a consequent decrease in the fuel delivery.

Abstract: 1,073,960. Superconductor devices. AVCO CORPORATION. Dec. 24, 1964 [April 22, 1963], No. 50909/63. Heading H1K. [Also in Division H2] Current is induced in a superconductive circuit, which includes a plate member, by traversing a magnetic flux, which passes through a normal region in said plate, across said plate without breaking the circuit so that it effectively links with the closed circuit. In Fig. 2 (not shown), the superconductive circuit comprises a coil (46) and plate (21) situated in the air gap (22) of laminated core (23) which comprises pole member (24), yoke (25) and a second pole (26) which has depending legs (27-32) each carrying field coils (33-38) respectively. In operation, the field coils are sequentially energized through switch (54) so that the magnetic field produced, which is greater than the critical field of the superconductor, is traversed from edge (41) to edge (42) of the plate; coil (34) being energized before coil (33) is switched off and so on. All coils are then de-energized and the current may be increased by traversing the field from edge (41) again, or decreased by traversing the field from edge (42). In a modification the field of a continuously energized magnet is controlled by providing a matrix of continuously energized superconducting wires between the poles and the superconductive plate which are de-energized in sequence to cause the magnetic field to traverse the plate. In a further modification air-cored coils are used to provide the moving field, Fig. 8 (not shown). In another form of generator, Fig. 3 (not shown), the magnet core 62 or superconductor plate (64) is moved relative to one another; coil (61) being switched off during movement in one direction. It is also contemplated to use an A.C. energized field system in conjunction with a superconductive plate having copper plates on its surface so that localized eddy-current heating occurs thus causing the plate to become normal at this point.
