Title: Apparatuses for indicating relative compression differences in a multi-cylinder internal combustion engine
IPC: G01L23/08
Filed: 1975-02-27
Abstract: 1467551 Monitoring cylinder pressure in I C engines: monitoring voltage peaks SVENSK BILPROVNING AB 27 Feb 1975 [4 March 1974] 8325/75 Headings G1N and G1U Excessive variation between the cylinder pressures of an I.C. engine are detected by looking for excessive variation in the peaks of the starter motor current whilst the starter motor is turning the, non- firing, engine. As described in a first embodiment the starter motor current which is detected by a Hallplate pick-up 1, 2, Fig. 2, has an initial peak Ap, Fig. 1 which is detected 3, Fig. 2, to set on a monostable 4. The first peak, A1, Fig. 1, after the monostable 4 resets is sampled and held 7, and each subsequent peak, typically peak Ar, is compared with A1 by an arrangement 8, 9, which only produces an output to set a trigger 11 'on' whenever k|A1-Ar|#A1, k being a pre-set constant determined by a feedback resistor 14. The setting on of trigger 11 sets a trigger 12 to provide a visual indication 13 of the existence of excessive pressure differences. The above process continues until a counter 6, which was reset to zero by the output from the monostable 4 and which has subsequently been counting the peaks A1, A2, ... &c., becomes full, whereupon the next peak to occur is sampled and held 7 in place of the peak A1, and the trigger 11, if on, is reset off. The process then continues, as above, but with the peak A 1 replaced by a more recent peak. In a second embodiment Fig. 4 (not shown) each peak, after the initial period td, Fig. 1, to allow transients to die out, is compared with a pre-set fraction of the largest of the peaks that precedes it.

Abstract: 1,115,215. Hybrid transformer circuits. STANDARD TELEPHONES & CABLES Ltd. 24 Feb., 1967, No. 8976/67. Heading H4R. The balancing network 4 of a hybrid transformer circuit, Fig. 2, has variable components 6, and 7, which are adjusted by error signals derived from signals from the upper and the lower parts of the frequency spectrum extracted from both the receiving pair 2 and the sending pair 5 so as to eliminate echoes in the sending pair 5 of signals in the receiving pair 2. Signals in the receiving pair 2 are selected by filters 10 and 11 to extract frequencies of respectively 500 and 2000 c.p.s., which, via phase-shifters 14 and 15, operate gates 16 and 17. The gates inputs are derived from the same respective frequency components in the send line 5 selected by filters 12 and 13 which are alternately connected, by the switches 22a and 22b, to the respective gates 16 and 17, the outputs from which drive, via amplifiers 18 and 19, the motors 20 and 21 to control the values of resistors 6 and 7. Only echo signals in send pair 5 due to signals in line 2 will be effective to drive motors 20 and 21 since all other signals will be uncorrelated. Amplifier 23 prevents signals from the two wire line 3 reaching the inputs of filters 10 and 11 since signals from the two wire line in the send and receive pairs would be correlated. In an alternative embodiment the filters 10 and 11 are replaced by oscillators of the respective frequencies 500 and 2000 c.p.s. which alternately feed signals into the line 2 and also supply gating signals to the gates 16 and 17, Fig. 3 (not shown). The system would be energized for a short time at the commencement of each connection.

Abstract: 892,231. Control of D.C. motors. ENGLISH ELECTRIC CO. Ltd. March 23, 1959 [March 21, 1958], No. 9230/58. Class 38 (3). [Also in Group XXXV]  The speed of a D.C. motor, having its armature connected to a supply through a gridcontrolled current converter, is controlled by a device responsive to the deviation of the motor speed from a reference value advancing the grid phase of the converter continuously from a phase corresponding to a high inverter voltage to a phase corresponding to a high rectifier voltage as the said deviation in motor speed increases in magnitude with a decrease in the motor speed below the reference value, a further device reversing the motor back E.M.F. relative to the converter and the sense of the speed deviation relative to the grid control device, whenever said deviation reverses in sense. As shown, an armature 10a of a motor 10 is supplied from a transformer 12 through a grid-controlled current converter 11. The voltage of a tachogenerator 19, coupled to the motor, is compared with a reference voltage selected by a speed control lever 18 positioning a slider 17a. The resultant voltage is applied to reversing contacts 20a, 20b and to reversing contacts 25a, 26a. Movement of the speed control lever from the neutral position closes contact 25a or 26a to apply the resultant voltage to an errorsensing amplifier 28 that limits the amplitude of the signal fed to a relay 27 that changes over contacts 27a, 27b when the signal applied to it reverses and reaches a predetermined magnitude. Contacts 25 or 26 are closed by the movement of the control lever from the neutral position and a relay 23 or 24 is energized to close contacts 16a or 16b and energize a field winding 14a of an exciter 14 supplying a field winding 106 of the motor 10. Polarized relays 29a, 29b are energized by the voltage drop across a resistor 30 and the appropriate relay changes-over contacts 20a, 20b so that the resultant voltage is applied in the correct sense to a negative error suppressing device 21, the positive-going output signal from which is fed to a control winding 22a of a grid control device 22 to vary the grid phase of the current converter 11 so that with increase in positive signal amplitude the converter changes from operating as an inverter to operating as a rectifier. In a modification, the relays 23, 24 reverse the armature connections instead of the field winding of the motor 10.
