Title: Interference fringe counting system and method
IPC: G01D5/38
Filed: 1970-01-22
Abstract: 1292902 Fringe counting THOMSON-CSF 22 Jan 1970 [23 Jan 1969] 3257/70 Heading G4H In a fringe counting system for a Michelson interferometer, the fringe system is detected by photo-electric detectors, so spaced that there is a phase shift between the signals from the detectors. The output from the detectors pass through Schmitt triggers 11, 12, differentiating circuits 21, 22 and polarity detectors 36, 32. The outputs on P 1  and P 3  are caused by the input signal at A exceeding a positive threshold value or negative threshold value respectively. Outputs P 2  and P 4  function similarly for the input signal 3. Outputs P 1 -P 4  are fed into a logic circuit 4 containing AND, and OR gates and bi-stables. The output signal from the logic circuit 4 appears on C 1  or C 2  according to the direction of movement of the fringes. This output passes via isolators 61, 62 (to prevent pulse feedback), delay circuit 7 to counter 8. The outputs C 1  and C 2  are also fed to a flip-flop 5, which controls the direction of count in counter 8.

Title: Torque convertor assembly
IPC: F16H45/02
Filed: 1960-01-29
Abstract: 932,698. Clutch combinations. BORG. WARNER CORPORATION. Jan. 29, 1960 [Feb. 5, 1959; March 13, 1959], No. 3318/60. Class 80 (2). [Also in Group XXIX] A torque converter assembly comprises a housing 2, 3 an axially movable pressure plate 27 dividing the interior of the housing into a chamber 41 for a clutch 23 and a chamber 42 for a converter 7, a selector valve DV for directing fluid pressure from a source P into the clutch chamber to disengage the clutch or into the converter chamber to engage the clutch, restricted orifice means 32 in the pressure plate affording communication between the chambers and unidirectional valve means 29 controlling the restricted orifice means to permit fluid communication between the chambers when the selector valve directs the fluid to the clutch chamber whereby the clutch is disengaged and the converter charged simultaneously. The pressure plate is constrained to rotate with the housing by lugs 38 engaging the heads of studs 5 and is axially movable on a hub 12 which carries the turbine blades 8 of the converter and is splined to an output sleeve 13 connected to the gearing of the transmission. The sleeve 13 is disposed within a stationary sleeve 16 supporting a one-way clutch 15, such as described in Specification 763,353, carrying the reactor blades 9, and the sleeve 16 is disposed within a driving sleeve 11 connected to the housing 2, 3 and impeller blades 6. A central shaft 13, connected to the output of the transmission, is supported in a bearing 21 and carries the hub 22 of a clutch and vibration damper assembly 23, such as described in Specification 872,676. A passage 43 between the shaft 19 and sleeve 13 and a passage 44 between the sleeves 13, 16 are joined by passages 24, 18 to the clutch and converter chambers 41, 42 and to the selector valve DV which is connected to a pump P and reservoir, which may be those of the engine driving the assembly. When the selector valve is positioned, as shown, to connect the pump to the passage 43 and chamber 41, the pressure plate is moved to disengage the clutch and fluid can pass through the restricted orifices to the chamber 42 to fill the converter by lifting the unidirectional valve means, which consists of a resilient plate 29 in a groove in a bearing 25 for the pressure plate, away from the orifices, the pressure drop across the orifices ensuring that the plate moves. Fluid can at the same time leave the converter chamber through the passages 18, 14 and the valve DV, but the resistance to flow effected by the passage 44 maintains the pressure in the converter chamber at the required operative level. When the selector valve is positioned to connect the pump to the passage 44 and chamber 42, the fluid moves the plate 27 to engage the clutch and the resilient plate 29 prevents flow of fluid from the converter chamber to the clutch chamber. A relief valve RV controls the pressure of fluid supplied to the pump.

Title: Improvements in or relating to frequency shift telegraph receivers
IPC: H04L27/16
Filed: 1959-02-02
Abstract: 855,634. Automatic frequency control systems; frequency detectors. TELEFUNKEN G.m.b.H. Feb. 2, 1959 [Feb. 8, 1958], No. 3659/59. Class 40(5). In a Twinplex frequency shift telegraphy receiver the output. I varying linearly with frequency of a frequency control discriminator D is combined with a staircase voltage II of opposite slope to produce a sawtooth characteristic I + II whose longer sides cross the zero voltage line at points corresponding to the signal frequencies f1 - f4 so that the control voltage corresponding to any frequency drift is the same irrespective of the nominal frequency being received. As shown the discriminator output may be applied through a cathode follower to a parallel series of normally blocked and differently biased transistors T 1  - T 3  which open in succession to increase the total current through one winding of a polarized relay Re, having another control winding receiving directly the discriminator output, the two control windings being in opposition, so that the armature A is responsive to the sawtooth characteristic I + II. This operates one way or the other a motor controlling the receiver local oscillator frequency. An oscilloscope AR with vertical plates connected to the IF and horizontal plates either connected by a switch Sch to the discriminator output or to the sawtooth output through a third winding on the relay Rc may be used for monitoring the receiver, in the latter case incorrect adjustment of the discriminator output control potentiometer producing horizontal deflection of the beam for different frequencies. In a modification for a discriminator output decreasing with frequency, PNP transistors are used and the sawtooth has opposite slopes. In a further modification the discriminator D and transistors are not connected to a relay but to a combining resistance network, the transistor on successively becoming blocked allowing negative current from the supply source to pass through diode gates connected to their collectors to common output resistor. In a final modification the armature A connects a positive or a negative voltage source in series with the output of the discriminator D. so that the D.C. output follows a sawtooth waveform.

Title: Improvements in or relating to the production of cast-iron
IPC: C21B11/02
Filed: 1935-02-05
Abstract: 453,423. Extracting iron. TENNANT, W. J., 111, Hatton Garden, London- (Fondrilux Soc. Anon.; 5, Rue Philippe, Luxembourg) Feb. 5, 1935, No. 3742. [Class 72] [See also Group XII] In the production of cast-iron from ores in which sponge iron is produced in a shaft furnace and then melted in another furnace working independently of the first furnace, the ore is so treated with heating gases in the first furnace as to pass first through a zone at a temperature of about 700‹ C. where it is reduced and then through a zone at a temperature close to the sintering point e.g. at about 1000‹ C. to produce a vitreous coating on the reduced ore which prevents reoxidation when it is being transferred to the second furnace where it is melted. Carbon in any desired form such as coke, ashes, or charcoal is supplied to the melting furnace in such quantities as are necessary for the residual reduction of the iron sponge and for the carbonization of the cast-iron produced. If the silicon content of the cast-iron is not high enough silicon or ferro-silicon may be added. The heating value of the gases in the furnace may be increased by the addition of other gases e.g. exhaust gases. The shaft furnace 1, is provided with a conical or tapered bottom, the heating gas being supplied from a generator 3 and may be heated in a heat-exchanger 4 before it pssses into the gas supply pipe d. Air which is also heated in the exchange 4 is fed to the furnace 1 by a pipe e and the mixture of air and gas ignited by an igniting device f. The furnace 1 is provided with a discharge device c for the reduced ore which is then transferred to the melting furnace 2 which is an ordinary cupola furnace in which the blast nozzles are substituted by gas burners g fed with preheated gas from the generator 3 and air preheated in the exchanger 4. The exchanger 4 is heated by gases passing from the furnace 1 through a pipe b.
