Title: Improvements in or relating to telegraph translating circuits
IPC: H03K3/13
Filed: 1946-09-19
Abstract: 652,154. Code telegraphy. RADIO CORPORATION OF AMERICA. Sept. 19, 1946, No. 28157. Convention date, Sept. 26, 1945. [Class 40 (iii)] [Also in Group XL (c)] Apparatus responsive to pulse energy which shifts from one value representing a mark to a second value representing a space and which terminates at one of said valves comprises a tripping circuit coupled to an output circuit and controlled by said pulses and having two positions of stability, one of which represents a mark and the other a space, so that the tripping circuit comes to rest in one position determined by the value at which the pulse energy terminates, also includes means for restoring the tripping circuit to said one position of rest in case it has been tripped therefrom by energy due to static or other disturbance. The arrangement is preferably used in a system in which marks and spaces are transmitted by different frequencies which are fed to a limiter, discriminator and detector to derive bidirectional current which reverses the output polarity as the transmitted current shifts from the mark frequency to the space frequency and vice versa. The positive and negative impulses applied at 102 to a valve 104 are taken from a cathode resistor 108 and fed to the first valve 110 of a triggering pair and to a valve 150 which is made normally conducting by means of slight positive grid bias derived from a resistance 154 connected to a potential divider 155, 156. The valve 110 conducts on a mark and the valve 114 on a space, the output being taken from the plate circuit of either of the valves 110, 114, and from 114 as shown. If, at the termination of signal keying, the valve 114 has been left conducting due to a disturbance, since valve 150 gradually returns to its conductive state, the flow of current in this valve and through the resistance 123 will reduce the potential on the grid of valve 114 which cuts off and makes the valve 110 conductive. During the initial spacing pulse, valve 150 is made non-conducting and this applies a slight positive potential to the grid of the valve 114 and aids the triggering to be effected by the application of the normal spacing (negative) voltage to the grid of the valve 110. During keying, the mark impulses apply a slight positive potential to the grid of the valve 150, which conducts to a small extent and by reducing to some extent the positive voltage on the grid of the valve 114 aids the triggering of the valve 110 by the mark impulse. The cathode resistance 111 is variable so that in the case of input waves with sloping leading and trailing edges, the triggering voltages can be adjusted to produce output marking and spacing pulses of equal width, or widths of predetermined ratio, as indicated in connection with Figs. 2, 3, 4 (not shown).

Title: Process for the conversion of heavy or complex hydrocarbon oils into lighter oils
Filed: 1925-11-10
Abstract: 243,339. Donnelly, J. F. Nov. 21, 1924, [Convention date]. Hydrocarbons, cracking.-Hydrocarbon oil is heated to a cracking temperature under pressure to prevent vaporization while passing through a heated coil 3 and on discharge into a region of lower pressure is mixed with cooler oil to prevent decomposition to form tar and carbon. The oil is forced by a pump 4 through the coil 3 and is discharged through a nozzle 9 into an expansion chamber 8 having depending outlets 11 discharging into an outer tank 10. Oil from the base of the tank 10 is drawn through a pipe 12 by the injector action of the nozzle 9 or is forced by a pump 14 so as to mix with the heated oil immediately on discharge into the chamber 8. Steam or water may also be injected into this chamber. The vapours from the tank 10 pass through dephlegmating condensers 19, 18 to a final condenser 25. Condensate from the condenser 18 collects on a plate 20 and passes by a pipe 21 to a chamber 22 formed by a partition 23 in the tank 10. The condensate, mixed with fresh oil admitted through a float valve 30 to maintain a definite level, is drawn by the pump 4 through a pipe 36 and is forced through the coil 3. Oil from the tank 10 may be passed to the pump 4 by a pipe 37. The condensers 25, 18, 19 may be cooled by water passed in succession through them from a pipe 26, and through pipes 28, 31, to an outlet pipe 32, and the temperature of the condensers 18, 19 may be regulated by admitting more or less of the water from the pipe 28 to these condensers through the valves 29, 30. In an example, gas oil is forced through the coil 3 under a pressure of 70 atmospheres, and the temperature at the outlet end is 890‹ F.

Title: Method of and apparatus for ignition timing in internal combustion engines
IPC: F02P5/155
Filed: 1971-06-17
Abstract: 1343448 Ignition systems; timing ignition PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd 17 June 1971 [20 June 1970] 28446/71 Heading F1B Apparatus for timing the ignition of an internalcombustion engine includes means for performing a first position determination during the compression stroke before the desired instant of ignition and means for performing a second pos-- ition determination near the top dead centre, the ignition instant being determined from the first position determination by a delay circuit. The period of time between the ignition instant and the second position determination is measured, a measuring quantity being derived which has a certain relationship to the period, and this quantity is compared with a reference quantity and in the case of deviation the delay circuit is controlled to provide compensation. In the figure a crank-shaft pick-up comprises parts 13, 14 and 15. The signal generated in 15 is applied to an amplifier or pulse shaper 16 and from this to a delay circuit 17 which transmits the first position determination with a certain time delay to an output 20. The ignition instant is given by the appearance at the output 20 of the signal derived from the first position determination. The switch 5 is operated and the high tension system produces a spark. The signal from the second position determination appears at the output 20 without any time delay. Since the output 20 is connected to a measuring and comparing circuit 18, the time between the ignition instant and the second position determination may be determined. This period of time is compared in 18 with a reference quantity from a reference source 19 and when the quantity representing the measured period deviates from the reference quantity the circuit 18 applies through a lead 21 a control signal to the delay circuit 17 in a sense such as to reduce the deviation to a minimum. A detailed circuit diagram of the system is described in the Specification. The switch may be a transistor or thyristor or a reed type switch. The crank-shaft pick-up may comprise a disc mounted on the crank-shaft and cooperating with a light source and photo-sensitive diode but other types of pick-up are referred to.

Filed: 1956-09-21
Abstract: 845,757. Sorting by gauging. UNITED ENGINEERING & FOUNDRY CO. Sept. 21, 1956, No. 28897/56. Class 106 (2). Apparatus for sorting according to thickness sheets of tin-plate and other ferrous materials comprises a conveyer 13, thickness detecting means 11 and electromagnetic means 14 or 15 energized by the response of the detecting means to attract sheets not lying within required limits and direct them away from the conveyer 13 and towards a piler 18 or 22. Sheets of the correct gauge pass on to a piler 24. Sheet to be classified passes through a flying micrometer 11, a flying shear 12 and on to a revolving electromagnetic deflector roll 14. If the thickness of the sheet is less than the required limit, then micrometer 11 operates contacts which energize the deflector roll 14 through a time delay circuit so that this occurs just as the leading edge of the under-gauge sheet reaches roll 14. This being magnetized holds the sheet until it reaches a stripper 16 and it then rims beneath roller 19 down an inclined plane 17 to an under-gauge piler 18. If the thickness of the sheet is greater than the required upper limit, a second deflector roll 15 is energized and the sheet passes down an inclined plane 21 to an over-gauge piler 22. If the thickness of the sheet is within the required limits, neither of the rolls 14, 15, is energized and the sheet passes along conveyer 13 to piler 24.
