Title: Device for automatic control of electronic spark ignition advance for internal combustion engines
IPC: F02P5/15
Filed: 1976-05-28
Abstract: 1520943 Timing spark ignition FIAT SpA 28 May 1976 [10 June 1975] 22350/76 Heading F1B Ignition timing for an I.C. engine is effected by a circuit including 1st and 2nd pick-ups 8, 10, respectively co-operating with a protuberance (4), Fig. 2 (not shown) on a part rotating with the engine, e.g. on the side of flywheel 2, and with teeth 3 on the part, the output pulses from the 2nd pick-up 10 being counted in a counter 24 for a predetermined time commencing with the passage of protuberance (4) past the 1st pick-up 8; a memory means 40 including latch memory 34 and read only memory 42 stores the count after this time and provides a signal representing a reference value of the desired spark advance which is stored in a parking memory 48, the subsequent passage of (4) past the pick-up 8 acting to reset the pulse counter 24 and to clear the reference value from the memory means 40; a pulse selection network 36 then compares the reference value stored in parking memory 48 with the instantaneous count in counter 24 after the resetting thereof to initiate operation of the spark discharge circuit when the two are equal. The predetermined time is determined by a monostable 14 which produces an output pulse of the predetermined duration in response to the pulse from 1st pick-up 8. At the end of the predetermined time, pulse counter 24 continues to count until it reaches its maximum count when it provides an enabling signal to NAND gate 28 to close AND gate 20 to stop the count.
Patent GB-591795-A (GB)
Title: Improved form of flushing apparatus
IPC: E03D3/04
Filed: 1944-11-13
Abstract: 591,795. Pilot valve apparatus. BAILEY, S. R., and WILD & CO., Ltd., A. G. Nov. 13, 1944, No. 22352. [Class 135] A flushing apparatus comprises a main valve 12 between the inlet 3 and outlet 5 and provided with a differential hollow piston 6, which normally keeps the valve, in the closed position due to higher liquid pressure in the chamber 7. Pressure in the chamber 7 is maintained by water from the inlet leaking past the piston. A passage 20 through the valve and piston is normally closed by a mushroom valve 22 which, when tilted. by means of a handle 32, allows the liquid in chamber. 7 to escape to the outlet and the greater pressure then acting on the under surface of the piston will raise the latter and open the main valve to allow the main flush to start. A sleeve 15 carried by the main valve, guides the latter and allows the flushing water passing through an aperture 16 in the sleeve to exert an extractor action on water flowing down through passage 20. The main valve will close as soon as sufficient water has leaked past the piston to build up pressure again in chamber 7: Tilting of the stem of valve 22 is effected by a spring-loaded rod 30 which receives an axial movement on tilting of handle 32. Valve 22 is maintained in the closed position by flat spring 24. A baffle sleeve 34 on the main valve prevents the delivery water from obstructing flow of water through passage 20.

Title: Improvements in the manufacture and production of aromatic hydrocarbons
IPC: C07C2/76
Filed: 1926-09-17
Abstract: 258,608. I. G. Farbenindustrie Akt.- Ges. Oct. 12,1925, [Convention date]. Aromatic hydrocarbons, mainly of the benzene series, are produced by passing a methane-containing gas at an elevated temperature and pressure over a catalyst comprising a carbonate or other salt of the alkaline earth metals including magnesium and beryllium, or an oxide or hydroxide of magnesium and beryllium, or a compound of selenium, tellurium and thallium, or consisting of active silica or active charcoal or mixtures of these substances with each other or with other materials. Temperatures of 450‹- 800‹ C. are generally employed in conjunction with pressures ranging from 50 to 1000 atmospheres. According to the example, a liquid rich in benzene hydrocarbons is obtained by passing natural gas, which consists chiefly of methane together with ethane, propane and ethylene, at a pressure of 150 atmospheres through a vessel filled with active silica and maintained at a temperature of 600‹ C. The Specification as open to inspection under Sect. 91 (3) (a) also described the use of gas mixtures containing methane homologues or unsaturated hydrocarbons, particularly olefines, in addition to the methane as being especially useful and states that it is therefore advantageous to employ gases resulting from the distillation or decomposition of coal, tars and mineral oils; it further states that temperatures of 600-900‹ C. are employed in the process; this subject-matter does not appear in the Specification as accepted.

Abstract: 1419413 Distance measurement DIGITECH INSTRUMENTS Ltd 15 May 1973 23086/73 Headings G1A and G1M The movement of a device along a reference bar 11 is measured by photo-electrically sensing the rotation of a roller 31 which engages the bar. The roller can be moved in a direction arrows A, Fig. 3 transverse to the direction of movement of the device, to enable calibration of the device, but cannot be moved within the housing of the device in said direction of movement. As shown, the roller is tapered, so that for a given translational movement, a different angular movement of the roller is obtained for each position of engagement of the roller with the bar. The rotation of the roller is sensed at both ends of the roller, by lamp and photocell combinations which view markings on transparent glass or plastics discs 52. Also adjustable for focussing light on the marks are the positions of the lens 57 and lamp 58; which are carried in a housing slidably adjustable along pillar 67. The photo-cells 63 are aligned with the marks on the disc during setting up of the device and then fixed by cementing, glueing etc. The scales on the digitizer discs may provide coarse and fine measurements. The processing circuit may include conventional squaring (Schmitt trigger) circuits and digital display or control output.
